In view of the dead body in the room, Gu Chen did not dare to neglect, so he quickly contacted the Wangchao Town Police Station and asked Zhang Wenxia to transfer all the police officers who could be transferred to the scene of the accident.
On his side, after controlling Zhou Zheng, he continued to come to the door.
Seeing that the door lock was intact, but it was the simplest lock cylinder, Gu Chen immediately felt that anyone who was good at picking locks could basically pry it open.
Therefore, the door of Zhou Zheng's room is almost useless to this kind of people.
But after all, Zhou Zheng himself said that he just saw Yuan Jialiang passing by his residence early in the morning, and then walking towards the mountain.
Obviously, according to what Zhou Zheng said, the two hadn't met each other this morning.
But even so, Yuan Jialiang died in Zhou Zheng's room, which made Gu Chen feel that the murderer seemed extraordinarily arrogant.
He even knew that Zhou Zheng was not at home.
Turning his head to look at Zhou Zheng who was trembling behind him, Gu Chen asked again: "When you saw this man going up the mountain today, what time was it?"
"About...around 9 o'clock?" Zhou Zheng said.
"Then what time did you leave the room and go down the mountain?" Gu Chen asked again.
"It's...it's like 9:30." Zhou Zheng also said in retrospect.
"9:30?" Lu Weiwei was muttering, and she couldn't help but say: "That is to say, after 9:30, you went down the mountain, and you didn't meet anyone after that? Until you met us when you came back?"
"Yes." Zhou Zheng was also quite frightened at the moment, and he quickly nodded and admitted: "I went down the mountain around 9:30, and went to the vegetable field at the foot of the mountain."
"Anyway, I didn't meet anyone else along the way. I only met you when I came back."
"However, I really don't know why this person is in my residence? My room? I obviously have a locked door."
"Haven't the windows around you been opened?" Yuan Shasha also asked.
Zhou Zheng shook his head: "All are closed and locked from the inside."
"Although some ventilation windows are open, they are all fixed with steel bars to prevent theft, and people can't get in at all."
According to Zhou Zheng, Lu Weiwei also confirmed it again, and then returned to Gu Chen, confirming:
"He is right. The windows in the room do have steel anti-theft guardrails."
"I said, I really don't know why this person died in my room?" Zhou Zheng felt wronged, but after thinking about it, he said quickly:
"Maybe, maybe this person came here with the murderer after I left, but they saw that the door was locked, so they broke open the door by themselves, went into the room to rest, and then..."
Looking up at Gu Chen, Zhou Zheng also guessed and said: "Then, he had a conflict with the murderer, was killed by the murderer in the room, and then the murderer escaped."
"But this person was obviously poisoned to death." Lu Weiwei also reminded.
"However, none of the tableware here seems to have been touched." Zhou Zheng also reminded.
Yuan Shasha also nodded silently: "That's right, I have checked the kitchen, the tableware is neatly arranged, and there is no sign of being tampered with."
"Of course, it does not rule out that the murderer washed the tableware after poisoning the deceased, or took the tableware with the poison with him."
"Zhou Zheng." As soon as Yuan Shasha finished speaking, Gu Chen reminded, "Come with me to the kitchen."
"Okay." Zhou Zheng didn't dare to refute now, he could only stand up obediently, and hurriedly followed behind Gu Chen.
Everyone came to the kitchen together, Gu Chen stepped aside and continued to remind, "Check your kitchen and focus on what items are missing?"
"Wait a minute." Hearing Gu Chen's remarks, Zhou Zheng squinted his eyes and began to investigate.
However, after a while, Zhou Zheng shook his head: "Comrade policeman, all the tableware is here. I don't have a few tableware in the kitchen, anyway, that's all there is."
"Collect all these things." Gu Chen also reminded.
Fortunately, Yuan Shasha carried some transparent evidence collection bags in her carry-on bag.
So all the tableware and cups were wrapped in transparent evidence collection bags, numbered, and photographed for evidence collection.
Gu Chen reminded Zhou Zhengdao: "We will bring these things to the Technology Bureau of the Municipal Bureau later to test the residual substances."
"Yes." As soon as Gu Chen finished speaking, Zhou Zheng bowed his head and readily agreed.
Zhou Zheng spared no effort to cooperate with the police wherever he could.
I feel that as long as I can get rid of my suspicions, I must go all out.
Since it takes time to wait for support, Police Officer Wang and Yuan Shasha stayed here to protect the scene after sending Zhang Wenxia a specific location.
And sent Gu Chen and Lu Weiwei, together with Zhou Zheng, to the wild grave on the mountain to check the situation.
The three of them walked for about half an hour, when Zhou Zheng suddenly stopped, pointed to a square in front of him and said, "The wild grave is over there."
Gu Chen and Lu Weiwei took a step forward, and there was an open space between the mountains, where a raised hill appeared.
At first glance, it is just a raised hill, but the surrounding weeds seem to have been cleaned up.
From this point of view, it does look like the prototype of a tomb.
"How can you tell that this is a wild grave?" Gu Chen asked Zhou Zheng.
Zhou Zheng waved his hand: "I didn't know at first, but I also heard from that person later. He said that the purpose of his going up the mountain was also to come to worship."
"But I'm very puzzled. Since he came from such a long distance, and he came here to worship for several days in a row, it feels quite strange."
"Besides, he has so many days, why doesn't he erect a stone tablet for this wild grave?"
Also listening to Zhou Zheng's words, Gu Chen and Lu Weiwei walked slowly to the so-called wild grave.
At this time, the weeds around the "wild grave" were completely cleared, not only that, even the weeds on the top of the wild grave were also cleared, and some new soil was filled in.
Gu Chen was puzzled, but also shook his head: "It's too weird, what does this Yuan Jialiang mean? He has been to Jiangnan City before?"
"How did he know that there is a wild grave on this mountain? Who is buried in the wild grave?"
"I don't know." Zhou Zheng walked up to Gu Chen and also explained:
"I've lived on the mountain for so long, and I've never heard of it. That's this, this man named Yuan Jialiang. After he came, I realized that this is a wild grave. I didn't know it at all before. Notice."
"Wait for the colleagues from Wangchao Town Police Station to come to support and confirm the situation here." Gu Chen said.
"En." Lu Weiwei nodded silently, then looked around, also curiously said:
"You said, this Yuan Jialiang, who comes here every day, just walks around the wild grave on this mountain? It can't be that simple, can it?"
"And he leaves early and returns late every day, for 10 consecutive days. Is he crazy?"
"How do I know that?" Zhou Zheng shook his head.
But Lu Weiwei said unhappily: "You said that you are a hermit, and you have stayed on the mountain for so long. For this kind of sudden visit from the provinces, you don't want to know more about him?"
"Comrade policeman." Seeing that Lu Weiwei made her way to the end, Zhou Zheng was also speechless and said:
"I came here because I wanted to be quiet. I don't like places that are too lively, really."
"So what if there are people coming up the mountain? Anyway, there will be some people coming up the mountain one after another, but not many."
"I don't want to get involved in these people's affairs, but I don't like these people to disturb me very much. I just want to be quiet."
"Okay." Seeing that Zhou Zheng was also depressed at the moment, Gu Chen didn't make things difficult for him for the time being, and reminded him:
"We will send all the tableware in your kitchen to the technical department of the Municipal Bureau for inspection. I hope no residual toxic substances are detected, otherwise you'd better give me a reasonable explanation."
"Yes, yes, yes." It feels like this kind of thing is going to happen, and he can only accept his fate, so Zhou Zheng is also breaking his cans now.
After several people checked around the wild tomb, they returned to the ancient temple.
At this moment, Zhang Wenxia has brought two police officers and several enthusiastic people to the scene.
Just in time to meet Gu Chen who came down from the mountain.
Zhang Wenxia also hurried forward to say hello: "Gu Chen, I have already brought the person you want, and I am afraid that there will not be enough manpower, so I called some enthusiastic people over."
"Have you brought anything?" Gu Chen asked.
"Is this okay? I borrowed a stretcher from the health center." Zhang Wenxia gave up a seat, and an enthusiastic crowd immediately put the folding stretcher in front of her.
"Yes." Lu Weiwei nodded silently.
Zhang Wenxia said again: "I have already brought the cloth for wrapping the corpse. This place has inconvenient transportation, so we can only use a stretcher to transport the corpse out, and then take the railway."
Before Zhang Wenxia finished speaking, Police Officer Wang had already walked out of the house.
Seeing Zhang Wenxia too, Police Officer Wang quickly asked her, "Zhang Wenxia, what happened to the wild grave on the mountain? Was there a corpse buried here?"
"Uh……"
Hearing Officer Wang's words, Zhang Wenxia froze for a moment, then shook her head: "This... I don't know very well."
"Maybe." As soon as Zhang Wenxia finished speaking, an enthusiastic crowd behind him answered, "I heard from the older generation that an unknown corpse was once buried on the mountain here."
"Because it's been a long time, few people know about it, and it's not clear who the corpse is. So no one erected an inscription or anything like that."
"Then do you know anything else about this wild grave?" Seeing that the enthusiastic crowd seemed to understand something, Gu Chen quickly asked again.
The enthusiastic crowd shook their heads: "I don't know about the others. I also heard from my grandparents. As for where is the wild grave? Actually, I don't know. After all, the wild grave has been there for many years."
"It is estimated that the grass on the head of the grave has already covered the wild grave. My friends and I have come here to play a few times, and we have also been to the top of the mountain, but we have never found the location of the wild grave."
"That's right." Just as the man here finished speaking, another fat and enthusiastic crowd quickly echoed:
"I've been to this mountain several times, but I haven't seen any wild graves? I just heard about it."
"That's strange." Hearing what the two said, Gu Chen frowned slightly, and said in wonder:
"You local people don't know much about the situation of this wild grave, and you can't even find out the specific location of this wild grave."
"But Yuan Jialiang, an outsider, was able to find it accurately, and even helped clear the weeds in this wild grave. What is he doing?"
"Or, the people buried in this wild grave may be his relatives?"
"This...is very possible." Hearing what Gu Chen said, Police Officer Wang also felt that the grave was a bit strange.
Thinking of Gu Chen and Lu Weiwei, who had just come down from the mountain, Police Officer Wang hurriedly asked Gu Chen again:
"By the way, Gu Chen, you and Lu Weiwei came down from there just now, what's going on there?"
"All the weeds around the field grave were removed, maybe this Yuan Jialiang did it?" Gu Chen said.
Officer Wang flicked his right index finger: "That is to say, this Yuan Jialiang came to this mountain these days just to visit this wild grave?"
"However, how can he know the exact location of the wild grave?"
"Perhaps, someone told him." Gu Chen also speculated.
Everyone stood at the door and talked for a while, and then they took everyone to the room, wrapped Yuan Jialiang's body in cloth and tied it tightly, and then carried the body onto a stretcher.
Afterwards, two police officers saw the scene and sealed it off, and Gu Chen also completed all the photos and evidence collection.
Due to the need to find out the specific situation as soon as possible, especially the origin of the wild grave, Gu Chen walked up to Zhang Wenxia and whispered:
"Senior Sister Zhang, can this wild grave be excavated to see who you are?"
"this……"
Hearing what Gu Chen said, Zhang Wenxia suddenly trembled: "This...isn't that good? After all, it's disrespectful to the dead."
"Although I don't know the specific identity of this person, but I always feel..."
"However, if this wild tomb is not excavated, it will be impossible to confirm the specific identity of the people buried in the wild tomb."
"So it is impossible to confirm what kind of relationship this person has with Yuan Jialiang?"
Before Zhang Wenxia finished speaking, Gu Chen also expressed his thoughts.
Zhang Wenxia nodded silently: "I know, for your criminal investigation team, this is an important clue."
"Or, I'll contact the village cadres in the nearby villages first. If none of them claim it, then you can definitely lead someone to dig out the wild graves and bring the corpses back for testing."
"After all, it is unclaimed and complies with the regulations. What do you think?"
"Then I'll have to thank Senior Sister Zhang." Seeing that Zhang Wenxia also gave the best solution, Gu Chen was naturally relieved.
Subsequently, two police officers stayed at the scene of the accident to deal with follow-up matters.
Gu Chen, Lu Weiwei, Police Officer Wang and Yuan Shasha, together with Zhang Wenxia, carried Yuan Jialiang's body down the mountain with the help of several enthusiastic people.
And Zhou Zheng, who also followed Gu Chen and the others down the mountain, will also return to Wangchao Town Police Station with everyone for further investigation.
...
...
It was already 3 p.m. when we returned to the Wangchao Town Police Station.
So under Zhang Wenxia's arrangement, everyone ate some light meals.
Due to the small scale of the Wangchao Town Police Station, the number of police officers is also very small.
A few years ago, when the population was small, it was set up as a police office.
In recent years, due to the good agricultural development, green enterprises have begun to take root in Wangchao Town.
Wangchao Town has just changed from population outflow to population inflow.
But even so, there are only five police officers in the entire Wangchao Town Police Station.
In the future, according to the population size, the police force will be gradually increased according to the situation.
However, after Gu Chen called for support, at around 3:10 in the afternoon, Gao Chuanfeng's team from the Technical Section of the Municipal Bureau also drove to the gate of the Wangchao Town Police Station.
"Gu Chen." Gao Chuanfeng got out of the car and walked towards Gu Chen. The two forensic assistants beside him also brought related accessories.
Including body bags and other materials.
Gu Chen put down the empty lunch box he had just finished eating, pointed to the stretcher on the ground and said, "He is here, and it is preliminarily inferred that he died of poisoning. You should take it back for testing first."
"In addition, we still have some packaged tableware here. You can also take it back for testing. If you have any results, please notify us immediately."
"Eat so late?" Listening to Gu Chen's introduction, Gao Chuanfeng walked up to Yuan Jialiang's body, opened the shroud, and started on-site inspection.
Several forensic assistants also surrounded him.
On the other hand, Zhang Wenxia is still actively contacting the nearby village cadres, repeatedly confirming the identity of the wild graves on the mountain.
As for Zhou Zheng, because the place where Yuan Jialiang died was Zhou Zheng's bedroom, Zhou Zheng was temporarily detained here for further interrogation.
After completing the preliminary inspection, Gao Chuanfeng asked two assistants to put the body into a body bag, hand over the other items by the way, and take them into the car together.
When he came to Gu Chen, Gao Chuanfeng said again: "Gu Chen, I heard that Bureau Qin is still angry about the matter in Wangxian Valley. The whereabouts of He Xu and Zhang Fan's criminal gang are unknown, which makes Bureau Qin very confused. fire."
"After all, there were a lot of police officers sent to search the mountain, and one hostage was rescued in the end, and the others disappeared, just like disappearing from the world."
"So these days, Bureau Qin is also holding meetings every day, and has been urging to find the whereabouts of He Xu and Zhang Fan."
After a pause, Gao Chuanfeng said again: "So, you have to speed up the progress of the case. Bureau Qin still has great hopes for your side."
"If you have a breakthrough here, then our eucalyptus will be fully revitalized. Therefore, Bureau Qin has also issued an order to let all our departments actively cooperate with your criminal investigation team of Furong Branch."
"I know." Hearing Gao Chuanfeng's words, Gu Chen was not surprised at all.
After all, Zhao Guozhi had issued a military order in front of Qin Gang.
Now the pressure is naturally on my side.
Due to the particularity of He Xu and Zhang Fan's identities, as well as the dens destroyed in Shanlan Town last time and the important evidence collected, Qin Gang was greatly surprised.
"Apricot"
Therefore, Qin Gang's focus during this time will naturally be on this end.
But the strange thing is that according to Gao Chuanfeng, the matter that Qin Gang attaches great importance to is on Zhao Guozhi's side, and he didn't hear any urging.
Of course, Gu Chen also knew very well that Zhao Guozhi took all the firepower, so he didn't urge himself.
The purpose is to avoid too much pressure on yourself, which will affect the efficiency of handling cases.
Zhao Guozhi has always been like this, fully trusting himself, so Gu Chen feels that the investigation work on his side also needs to be further accelerated.
Patting Gao Chuanfeng on the shoulder, Gu Chen also understood: "I know, I have also issued a military order here, and I must break it as soon as possible, and I will do it myself."
"That's good." Seeing that Gu Chen is in good condition, Gao Chuanfeng also warned: "I'll help you test the things you want immediately when I go back. If there are results, I will notify you as soon as possible."
"Okay, then I will trouble you." Gu Chen said.
After the two briefly explained a few words, Gao Chuanfeng got into the car and drove away from the Wangchao Town Police Station.
At this very moment, Zhang Wenxia happened to be walking over from the office area. Seeing the city bureau's vehicles leaving, she asked Gu Chen curiously, "They left?"
"Yeah." Gu Chen nodded silently.
"Oh, I didn't even ask them to drink water, so I left?" Zhang Wenxia looked a little disappointed because she also didn't see her colleagues from the Municipal Bureau.
But police officer Wang hurriedly asked Zhang Wenxia: "By the way, Zhang Wenxia, how is your contact going?"
"Ham, I have contacted the village cadres in the surrounding villages and asked them to go to the village to ask about the situation."
"As far as the current feedback is concerned, it seems that they don't know the specific identity of the wild grave."
"But in one village, the village cadre told me that when he went down to inquire about the situation, an old lady said that she seemed to know about the wild grave."
"Really?" Hearing what Zhang Wenxia said, Lu Weiwei was also very curious, and hurriedly asked, "Then...then now..."
"Now the village cadre has already driven the old lady here, and he will probably be here soon."
Here too Zhang Wenxia had just finished speaking, when a car stopped at the gate of the police station.
Zhang Wenxia slapped her thigh, pointed at the door and said, "Hey, maybe it's them."
"Officer Zhang." A middle-aged man walked into the office area with a white-haired old lady familiarly.
Seeing that everyone was there, and there were still some unfamiliar faces, the middle-aged man walked up to Zhang Wenxia and said, "I have already brought the person, what is the specific situation, you can ask her?"
"Old lady?" Seeing the white-haired old lady walking behind the middle-aged man, it was the old lady who gave her cucumber to eat. Lu Weiwei couldn't help but be taken aback: "So it's you?"
"Eh? Little girl?" The old lady glanced at Gu Chen who was beside Lu Weiwei, and said, "Young man, are you there?"
"Yes old lady, we meet again." Seeing this energetic old lady, Gu Chen also smiled politely.
Police officer Wang was very curious, and quickly asked Gu Chen, "Do you know each other?"
"She's the old lady who gave us cucumbers. When you and Xiao Yuan were walking back, didn't you just pass her by?" Lu Weiwei hurriedly reminded her.
On the other side, Yuan Shasha also suddenly realized: "Yes, we have seen it too."
"Old lady, sit down." Seeing that the old lady is the important clue provider, Gu Chen quickly supported the old lady and sat on a seat, and then hurriedly asked her:
"Old lady, do you know that there is a wild grave on that mountain?"
"That's right." The old lady nodded silently, and said slowly, "That wild grave must have existed for about 15 years."
"It has existed for 15 years? Such a long time?" Yuan Shasha couldn't help being taken aback when she heard what the old lady said.
The old lady nodded silently: "Yes, that wild grave is also very strange, but few people should know about it now."
"If our village chief hadn't found me to inquire about it, I would have almost forgotten about it."
Seeing that the old lady really knew something, everyone immediately gathered around.
"Old lady, drink a glass of water." Zhang Wenxia politely handed a cup of freshly brewed tea to the rough hand of the old lady.
"Thank you." The old lady nodded silently, took a small sip, and then said:
"So, what do you want to know from my old woman?"
"We want to know who is buried in that wild grave?" Gu Chen said.
"An outsider?" The old lady raised her head to recall, and said involuntarily, "I remember that there should be an outsider buried in that wild grave."
"Also, that person seems to have died a terrible death. It's hard to confirm his identity. Some people say that he was a beggar. Anyway, there are different opinions, and we can't figure it out."
"A beggar?" Lu Weiwei was taken aback when she heard the old lady's words, and hurriedly asked, "Why is it a beggar?"
"Well, that's how it's called anyway?" The old lady drank her tea and said in retrospect: "It's the kind of person who asks for money on the street, with an erhu in his hand, walks to the door of your store, and randomly plays Next. Then I will ask you for money."
"If you don't give it, he will keep pulling and pulling. If there are some businessmen who are afraid of affecting the mood of customers in the store, they will give a little. This is probably the case."
"So that's the case?" Yuan Shasha also understood after hearing what the old lady said, so she asked the old lady again:
"So old lady, this person is a foreigner, right?"
"Yes, it should be a foreign accent, I have seen it before." The old lady said.
"Then what happened afterwards?" Gu Chen hurriedly asked again.
"Later? Later, I heard that this person huddled in a warehouse to sleep at night, but the warehouse suddenly caught fire. That poor man was engulfed by the fire and burned alive."
Speaking of this, the old lady also looked distressed, and couldn't help frowning.
At this time, Zhang Wenxia also nodded silently, and echoed: "15 years ago, there was indeed a fire in Wangchao Town, but I was not here at that time, and I don't know the specific situation here."
"I understand." As soon as Zhang Wenxia finished speaking, the old lady continued:
"I remember that it was a sponge factory that was burning. Oh, the sponges are flammable. Once they burn, there is no way to put them out."
"Anyway, it feels like there was thick smoke billowing around the sponge factory that night. Many people participated in fighting the fire, but they couldn't fight the fire."
"After counting all the personnel, the owner of the sponge factory was sure that everyone was safe and sound, so he was relieved."
"It feels like the sponge is burning, so let's burn it, at least people are fine."
With a faint sigh, the old lady continued to recall: "Later, the fire brigade also came, but the fire has been burning for a long time, and there are ruins everywhere."
"It was only when everyone cleaned up the scene that they discovered that there was still a body that had been burned beyond recognition, just like a coke."
Speaking of this, the old lady couldn't help shivering, as if thinking about this situation, she felt her hairs stand on end.
"Then what happened later? How to deal with this matter?" Officer Wang asked.
The old lady took a sip of tea, frowned and said, "Later? Later, I remembered that the police from Wangchao Town also came to dispose of the corpse and asked who knew them? They wanted to identify the deceased."
"But everyone said they didn't know each other. After all, it's a coke that's beyond recognition. It's scary to look at."
"And the owner of the sponge factory was also arrested because people were burned to death in the factory, but the owner of the sponge factory bluntly denied that this was an employee of his factory."
"Moreover, the owner of the sponge factory seriously suspected that this person sneaked into his factory at night and set fire to the sponge, which caused the fire."
"After all, it's so good, how can it catch fire?"
After a pause, the old lady looked up at the ceiling and continued to think:
"Anyway, that year, I remember that no one recognized the deceased, and the owner of the sponge factory also confirmed the number of his employees and fully explained his situation."
"So, the police here can only put this case on hold temporarily, and use it as a fire caused by an unknown fire source for the time being."
"Then... this round of corpses." Lu Weiwei also continued to remind.
The old lady nodded: "The corpse has to be dealt with, because this person was originally a loner, and he may have come from other places to make money in the form of playing erhu for money."
"So, no one knows his identity, especially his erhu, which was burned to charcoal along with the fire that night."
With a heavy sigh, the old lady said again: "So at that time, how to deal with the corpse became a problem."
"Because of the special status, the relatives of the deceased could not be found for the time being, so several old policemen who have not retired here made a plan and asked everyone to temporarily bury the body nearby."
"When the relatives of the deceased come to the door, we can give an explanation and take the body away."
"But this waiting has been going on year after year, for fifteen years, and no one has come to pick up the corpse for fifteen years."
"And because of the surrounding villages, the big guys don't agree to bury the corpse in their village cemetery."
"So we came and went again and again, and everyone compromised, and we discussed to bury the body on the mountain."
"Just like that, a few older enthusiastic villagers buried the corpse there together."
"Since no one came to sweep the grave, the grave is probably covered by weeds long ago, and few people know the exact location."
"Yes." Hearing what the old lady said, Lu Weiwei hurriedly replied: "We have been near the wild grave, and the surrounding weeds have been cleaned up, and it feels like all kinds of weeds are piled up high."
"It can be seen how many years it has been since no one came to sweep the tomb and fill the soil? Just recently, this deceased named Yuan Jialiang came to the mountain for 10 consecutive days to worship him."
"I guess, this Yuan Jialiang is a relative of the deceased."
"But how did he know the specific location of the wild grave?" Gu Chen raised his own doubts and said involuntarily:
"After all, he is a provincial, and it is very strange that he can accurately find the location of the tomb."
"He can do things that many local people can't do."
"Also, according to Zhou Zheng, who lives in seclusion on the mountain, he has lived on this mountain for so long, and he has visited almost every corner of the mountain, but he has not noticed this wild grave."
"If Yuan Jialiang hadn't gone up the mountain to offer sacrifices and met Zhou Zheng, Zhou Zheng probably didn't know that there was a wild grave on this mountain."
"Yes." As soon as Gu Chen's voice came here, Lu Weiwei also agreed:
"Junior Brother Gu is right. I don't believe that no one gave Yuan Jialiang directions."
"Or, this Yuan Jialiang may have known the exact location of the tomb back then, but he hadn't been here for many years, and now he suddenly remembered this and came to worship again."
"Or, this fire was set by Yuan Jialiang back then, and it happened to burn to death this unidentified deceased. Out of guilt, he chose to come here to worship?"
Lu Weiwei said a lot about herself in one breath.
Gu Chen also snapped his fingers and said, "What Senior Sister Lu said makes sense, it's entirely possible."
Taking a deep breath, Gu Chen continued to explain to everyone:
"Think about it, everyone. This Yuan Jialiang came to Wangchao Town from Hubei Province. After booking a hotel, he opened it for more than ten days."
"If you want to say that he and those two Guangdong provinces who do channel e-commerce are all here to participate in the Wangchao Town Blueberry Picking Festival, I don't think so."
"After all, Yuan Jialiang doesn't seem to care much about the blueberry picking festival. From the first day he came to Wangchao Town, he started to go out early and return late to sacrifice to the deceased on the mountain."
"It can be seen that Yuan Jialiang's purpose is very clear, and he also knows the specific location of the tomb."
With arms crossed, Gu Chen also leaned on the seat, and continued:
"It can be seen from this that if there is no one to guide Yuan Jialiang, Yuan Jialiang can accurately find the right position."
"This further shows that Yuan Jialiang may have known the specific location of the tomb back then, or it may be like what Senior Sister Lu analyzed just now, this Yuan Jialiang may be an arsonist."
"Because I felt guilty for burning the deceased, so I came here to sacrifice, so that I can feel better."
"Hmm." Listening to Gu Chen's analysis, Police Officer Wang also added with his right index finger:
"There is another possibility, that is, this Yuan Jialiang is related to the deceased. He learned about the specific location of the wild grave through others, so he made a special trip to find it."
"The purpose is clear. He just came to worship the deceased, which shows the importance of the deceased to Yuan Jialiang. After all, he has been offering sacrifices for 10 consecutive days."
"If this Yuan Jialiang hadn't been killed on the mountain because of being poisoned, I guess he would continue to sacrifice."
"What the hell is this person doing?" Also listening to Police Officer Wang's explanation, Lu Weiwei felt that the situation seemed to be getting more and more complicated.
Gu Chen patted his thighs with both hands, stood up, walked back and forth in front of the crowd, and said analytically:
"Now there are two conclusions. One is that Yuan Jialiang was the culprit in the fire at the sponge factory, but because he burned the unidentified deceased to death, he has always felt guilty."
"But when he was buried that year, he knew the specific location, but after leaving here, he never came back."
"And then, because of the condemnation of his conscience, he felt a little guilty, so he chose to come here to worship and sweep the graves of the dead every day."
"As for the other one, Yuan Jialiang is a relative of the deceased, but because the bones have already been charred, it is impossible to judge. Therefore, he can only sacrifice every day for peace of mind."
...
Everyone also expressed their opinions on the identity of Yuan Jialiang and the deceased.
Soon, everyone reached a unified opinion from their differences, and then from a unified opinion to a disagreement, and then unified, and then disagreed...
After a heated argument, Gu Chen also said loudly: "Everyone be quiet."
Seeing Gu Chen speak, everyone also looked at Gu Chen.
"Junior Brother Gu, do you have an idea?" Lu Weiwei asked.
Gu Chen nodded silently: "You can compare this charred corpse with the deceased Yuan Jialiang."
"But it will be more difficult to detect, after all, this is a charred body and the other is also a cold body."
"I think there may be some breakthroughs between the two, but... because of the long time, it is estimated that it will be difficult to come to a result."
In the end, even Gu Chen lost confidence, and his tone became hesitant.
But Zhang Wenxia said indifferently: "It doesn't matter, I believe that the detection technology of the Municipal Bureau should have its own magic weapon."
"If it can be detected successfully, it will also be a major breakthrough for our profession."
"Yes." Gu Chen completely agreed with Zhang Wenxia's statement, and also reminded:
"So, Senior Sister Zhang, can we dig up that wild grave? Then extract relevant substances and conduct identification with Yuan Jialiang's body? See if there is any connection between the two."
"Uh." Seeing Gu Chen's attention on the wild grave again, Zhang Wenxia said with some uncertainty:
"Gu Chen, this corpse is already charred, and it's been 15 years, so... can this still be identified?"
"Don't worry about this." Seeing that Zhang Wenxia had concerns, Gu Chen also reminded: "It is possible to do it with a high probability."
"Higher temperature, organic solvents, acid-base reagents, urea, amides, etc., can all cause denaturation of DNA molecules."
"That is, the hydrogen bonds between the DNA double-stranded bases are broken, and the double helix structure is untied, which is also called DNA unwinding.
After a pause, Gu Chen said again: "But the fracture doesn't mean disappearing. Only when concentrated sulfuric acid can dehydrate and carbonize organic matter can it be said that DNA can be destroyed."
"As far as the incinerated corpse is concerned, it depends on how high the high temperature is? If it is based on the high temperature in the general sense of the human body, the DNA at this temperature is indeed mainly unrotated and denatured."
"Afterwards, under certain conditions, it can be rotated again after cooling down. These are also two important steps in PCR technology."
"PCR technology?" Zhang Wenxia didn't know what these majors belonged to, so she asked Gu Chen weakly:
"Gu Chen, what is this PCR technology?"
"PCR, the full name is polymerase chain reaction." Seeing that Zhang Wenxia didn't understand it, neither did the others present.
Gu Chen simply explained: "It is a molecular biology technique that uses the principle of DNA double-strand replication to amplify a large number of specific DNA fragments outside the body."
"The characteristic is...it can use a small amount of DNA as a template to rapidly amplify and obtain a large number of copies."
"Like the current PCR technology, it has been used in many fields of modern biology and related sciences. It is also widely used in molecular biology and can be used in many fields including biomedical research, criminal forensics and molecular archaeology. "

Please report us if you find any errors so we can fix it asap!
In view of the dead body in the room, Gu Chen did not dare to neglect, so he quickly contacted the Wangchao Town Police Station and asked Zhang Wenxia to transfer all the police officers who could be transferred to the scene of the accident.
On his side, after controlling Zhou Zheng, he continued to come to the door.
Seeing that the door lock was intact, but it was the simplest lock cylinder, Gu Chen immediately felt that anyone who was good at picking locks could basically pry it open.
Therefore, the door of Zhou Zheng's room is almost useless to this kind of people.
But after all, Zhou Zheng himself said that he just saw Yuan Jialiang passing by his residence early in the morning, and then walking towards the mountain.
Obviously, according to what Zhou Zheng said, the two hadn't met each other this morning.
But even so, Yuan Jialiang died in Zhou Zheng's room, which made Gu Chen feel that the murderer seemed extraordinarily arrogant.
He even knew that Zhou Zheng was not at home.
Turning his head to look at Zhou Zheng who was trembling behind him, Gu Chen asked again: "When you saw this man going up the mountain today, what time was it?"
"About...around 9 o'clock?" Zhou Zheng said.
"Then what time did you leave the room and go down the mountain?" Gu Chen asked again.
"It's...it's like 9:30." Zhou Zheng also said in retrospect.
"9:30?" Lu Weiwei was muttering, and she couldn't help but say: "That is to say, after 9:30, you went down the mountain, and you didn't meet anyone after that? Until you met us when you came back?"
"Yes." Zhou Zheng was also quite frightened at the moment, and he quickly nodded and admitted: "I went down the mountain around 9:30, and went to the vegetable field at the foot of the mountain."
"Anyway, I didn't meet anyone else along the way. I only met you when I came back."
"However, I really don't know why this person is in my residence? My room? I obviously have a locked door."
"Haven't the windows around you been opened?" Yuan Shasha also asked.
Zhou Zheng shook his head: "All are closed and locked from the inside."
"Although some ventilation windows are open, they are all fixed with steel bars to prevent theft, and people can't get in at all."
According to Zhou Zheng, Lu Weiwei also confirmed it again, and then returned to Gu Chen, confirming:
"He is right. The windows in the room do have steel anti-theft guardrails."
"I said, I really don't know why this person died in my room?" Zhou Zheng felt wronged, but after thinking about it, he said quickly:
"Maybe, maybe this person came here with the murderer after I left, but they saw that the door was locked, so they broke open the door by themselves, went into the room to rest, and then..."
Looking up at Gu Chen, Zhou Zheng also guessed and said: "Then, he had a conflict with the murderer, was killed by the murderer in the room, and then the murderer escaped."
"But this person was obviously poisoned to death." Lu Weiwei also reminded.
"However, none of the tableware here seems to have been touched." Zhou Zheng also reminded.
Yuan Shasha also nodded silently: "That's right, I have checked the kitchen, the tableware is neatly arranged, and there is no sign of being tampered with."
"Of course, it does not rule out that the murderer washed the tableware after poisoning the deceased, or took the tableware with the poison with him."
"Zhou Zheng." As soon as Yuan Shasha finished speaking, Gu Chen reminded, "Come with me to the kitchen."
"Okay." Zhou Zheng didn't dare to refute now, he could only stand up obediently, and hurriedly followed behind Gu Chen.
Everyone came to the kitchen together, Gu Chen stepped aside and continued to remind, "Check your kitchen and focus on what items are missing?"
"Wait a minute." Hearing Gu Chen's remarks, Zhou Zheng squinted his eyes and began to investigate.
However, after a while, Zhou Zheng shook his head: "Comrade policeman, all the tableware is here. I don't have a few tableware in the kitchen, anyway, that's all there is."
"Collect all these things." Gu Chen also reminded.
Fortunately, Yuan Shasha carried some transparent evidence collection bags in her carry-on bag.
So all the tableware and cups were wrapped in transparent evidence collection bags, numbered, and photographed for evidence collection.
Gu Chen reminded Zhou Zhengdao: "We will bring these things to the Technology Bureau of the Municipal Bureau later to test the residual substances."
"Yes." As soon as Gu Chen finished speaking, Zhou Zheng bowed his head and readily agreed.
Zhou Zheng spared no effort to cooperate with the police wherever he could.
I feel that as long as I can get rid of my suspicions, I must go all out.
Since it takes time to wait for support, Police Officer Wang and Yuan Shasha stayed here to protect the scene after sending Zhang Wenxia a specific location.
And sent Gu Chen and Lu Weiwei, together with Zhou Zheng, to the wild grave on the mountain to check the situation.
The three of them walked for about half an hour, when Zhou Zheng suddenly stopped, pointed to a square in front of him and said, "The wild grave is over there."
Gu Chen and Lu Weiwei took a step forward, and there was an open space between the mountains, where a raised hill appeared.
At first glance, it is just a raised hill, but the surrounding weeds seem to have been cleaned up.
From this point of view, it does look like the prototype of a tomb.
"How can you tell that this is a wild grave?" Gu Chen asked Zhou Zheng.
Zhou Zheng waved his hand: "I didn't know at first, but I also heard from that person later. He said that the purpose of his going up the mountain was also to come to worship."
"But I'm very puzzled. Since he came from such a long distance, and he came here to worship for several days in a row, it feels quite strange."
"Besides, he has so many days, why doesn't he erect a stone tablet for this wild grave?"
Also listening to Zhou Zheng's words, Gu Chen and Lu Weiwei walked slowly to the so-called wild grave.
At this time, the weeds around the "wild grave" were completely cleared, not only that, even the weeds on the top of the wild grave were also cleared, and some new soil was filled in.
Gu Chen was puzzled, but also shook his head: "It's too weird, what does this Yuan Jialiang mean? He has been to Jiangnan City before?"
"How did he know that there is a wild grave on this mountain? Who is buried in the wild grave?"
"I don't know." Zhou Zheng walked up to Gu Chen and also explained:
"I've lived on the mountain for so long, and I've never heard of it. That's this, this man named Yuan Jialiang. After he came, I realized that this is a wild grave. I didn't know it at all before. Notice."
"Wait for the colleagues from Wangchao Town Police Station to come to support and confirm the situation here." Gu Chen said.
"En." Lu Weiwei nodded silently, then looked around, also curiously said:
"You said, this Yuan Jialiang, who comes here every day, just walks around the wild grave on this mountain? It can't be that simple, can it?"
"And he leaves early and returns late every day, for 10 consecutive days. Is he crazy?"
"How do I know that?" Zhou Zheng shook his head.
But Lu Weiwei said unhappily: "You said that you are a hermit, and you have stayed on the mountain for so long. For this kind of sudden visit from the provinces, you don't want to know more about him?"
"Comrade policeman." Seeing that Lu Weiwei made her way to the end, Zhou Zheng was also speechless and said:
"I came here because I wanted to be quiet. I don't like places that are too lively, really."
"So what if there are people coming up the mountain? Anyway, there will be some people coming up the mountain one after another, but not many."
"I don't want to get involved in these people's affairs, but I don't like these people to disturb me very much. I just want to be quiet."
"Okay." Seeing that Zhou Zheng was also depressed at the moment, Gu Chen didn't make things difficult for him for the time being, and reminded him:
"We will send all the tableware in your kitchen to the technical department of the Municipal Bureau for inspection. I hope no residual toxic substances are detected, otherwise you'd better give me a reasonable explanation."
"Yes, yes, yes." It feels like this kind of thing is going to happen, and he can only accept his fate, so Zhou Zheng is also breaking his cans now.
After several people checked around the wild tomb, they returned to the ancient temple.
At this moment, Zhang Wenxia has brought two police officers and several enthusiastic people to the scene.
Just in time to meet Gu Chen who came down from the mountain.
Zhang Wenxia also hurried forward to say hello: "Gu Chen, I have already brought the person you want, and I am afraid that there will not be enough manpower, so I called some enthusiastic people over."
"Have you brought anything?" Gu Chen asked.
"Is this okay? I borrowed a stretcher from the health center." Zhang Wenxia gave up a seat, and an enthusiastic crowd immediately put the folding stretcher in front of her.
"Yes." Lu Weiwei nodded silently.
Zhang Wenxia said again: "I have already brought the cloth for wrapping the corpse. This place has inconvenient transportation, so we can only use a stretcher to transport the corpse out, and then take the railway."
Before Zhang Wenxia finished speaking, Police Officer Wang had already walked out of the house.
Seeing Zhang Wenxia too, Police Officer Wang quickly asked her, "Zhang Wenxia, what happened to the wild grave on the mountain? Was there a corpse buried here?"
"Uh……"
Hearing Officer Wang's words, Zhang Wenxia froze for a moment, then shook her head: "This... I don't know very well."
"Maybe." As soon as Zhang Wenxia finished speaking, an enthusiastic crowd behind him answered, "I heard from the older generation that an unknown corpse was once buried on the mountain here."
"Because it's been a long time, few people know about it, and it's not clear who the corpse is. So no one erected an inscription or anything like that."
"Then do you know anything else about this wild grave?" Seeing that the enthusiastic crowd seemed to understand something, Gu Chen quickly asked again.
The enthusiastic crowd shook their heads: "I don't know about the others. I also heard from my grandparents. As for where is the wild grave? Actually, I don't know. After all, the wild grave has been there for many years."
"It is estimated that the grass on the head of the grave has already covered the wild grave. My friends and I have come here to play a few times, and we have also been to the top of the mountain, but we have never found the location of the wild grave."
"That's right." Just as the man here finished speaking, another fat and enthusiastic crowd quickly echoed:
"I've been to this mountain several times, but I haven't seen any wild graves? I just heard about it."
"That's strange." Hearing what the two said, Gu Chen frowned slightly, and said in wonder:
"You local people don't know much about the situation of this wild grave, and you can't even find out the specific location of this wild grave."
"But Yuan Jialiang, an outsider, was able to find it accurately, and even helped clear the weeds in this wild grave. What is he doing?"
"Or, the people buried in this wild grave may be his relatives?"
"This...is very possible." Hearing what Gu Chen said, Police Officer Wang also felt that the grave was a bit strange.
Thinking of Gu Chen and Lu Weiwei, who had just come down from the mountain, Police Officer Wang hurriedly asked Gu Chen again:
"By the way, Gu Chen, you and Lu Weiwei came down from there just now, what's going on there?"
"All the weeds around the field grave were removed, maybe this Yuan Jialiang did it?" Gu Chen said.
Officer Wang flicked his right index finger: "That is to say, this Yuan Jialiang came to this mountain these days just to visit this wild grave?"
"However, how can he know the exact location of the wild grave?"
"Perhaps, someone told him." Gu Chen also speculated.
Everyone stood at the door and talked for a while, and then they took everyone to the room, wrapped Yuan Jialiang's body in cloth and tied it tightly, and then carried the body onto a stretcher.
Afterwards, two police officers saw the scene and sealed it off, and Gu Chen also completed all the photos and evidence collection.
Due to the need to find out the specific situation as soon as possible, especially the origin of the wild grave, Gu Chen walked up to Zhang Wenxia and whispered:
"Senior Sister Zhang, can this wild grave be excavated to see who you are?"
"this……"
Hearing what Gu Chen said, Zhang Wenxia suddenly trembled: "This...isn't that good? After all, it's disrespectful to the dead."
"Although I don't know the specific identity of this person, but I always feel..."
"However, if this wild tomb is not excavated, it will be impossible to confirm the specific identity of the people buried in the wild tomb."
"So it is impossible to confirm what kind of relationship this person has with Yuan Jialiang?"
Before Zhang Wenxia finished speaking, Gu Chen also expressed his thoughts.
Zhang Wenxia nodded silently: "I know, for your criminal investigation team, this is an important clue."
"Or, I'll contact the village cadres in the nearby villages first. If none of them claim it, then you can definitely lead someone to dig out the wild graves and bring the corpses back for testing."
"After all, it is unclaimed and complies with the regulations. What do you think?"
"Then I'll have to thank Senior Sister Zhang." Seeing that Zhang Wenxia also gave the best solution, Gu Chen was naturally relieved.
Subsequently, two police officers stayed at the scene of the accident to deal with follow-up matters.
Gu Chen, Lu Weiwei, Police Officer Wang and Yuan Shasha, together with Zhang Wenxia, carried Yuan Jialiang's body down the mountain with the help of several enthusiastic people.
And Zhou Zheng, who also followed Gu Chen and the others down the mountain, will also return to Wangchao Town Police Station with everyone for further investigation.
...
...
It was already 3 p.m. when we returned to the Wangchao Town Police Station.
So under Zhang Wenxia's arrangement, everyone ate some light meals.
Due to the small scale of the Wangchao Town Police Station, the number of police officers is also very small.
A few years ago, when the population was small, it was set up as a police office.
In recent years, due to the good agricultural development, green enterprises have begun to take root in Wangchao Town.
Wangchao Town has just changed from population outflow to population inflow.
But even so, there are only five police officers in the entire Wangchao Town Police Station.
In the future, according to the population size, the police force will be gradually increased according to the situation.
However, after Gu Chen called for support, at around 3:10 in the afternoon, Gao Chuanfeng's team from the Technical Section of the Municipal Bureau also drove to the gate of the Wangchao Town Police Station.
"Gu Chen." Gao Chuanfeng got out of the car and walked towards Gu Chen. The two forensic assistants beside him also brought related accessories.
Including body bags and other materials.
Gu Chen put down the empty lunch box he had just finished eating, pointed to the stretcher on the ground and said, "He is here, and it is preliminarily inferred that he died of poisoning. You should take it back for testing first."
"In addition, we still have some packaged tableware here. You can also take it back for testing. If you have any results, please notify us immediately."
"Eat so late?" Listening to Gu Chen's introduction, Gao Chuanfeng walked up to Yuan Jialiang's body, opened the shroud, and started on-site inspection.
Several forensic assistants also surrounded him.
On the other hand, Zhang Wenxia is still actively contacting the nearby village cadres, repeatedly confirming the identity of the wild graves on the mountain.
As for Zhou Zheng, because the place where Yuan Jialiang died was Zhou Zheng's bedroom, Zhou Zheng was temporarily detained here for further interrogation.
After completing the preliminary inspection, Gao Chuanfeng asked two assistants to put the body into a body bag, hand over the other items by the way, and take them into the car together.
When he came to Gu Chen, Gao Chuanfeng said again: "Gu Chen, I heard that Bureau Qin is still angry about the matter in Wangxian Valley. The whereabouts of He Xu and Zhang Fan's criminal gang are unknown, which makes Bureau Qin very confused. fire."
"After all, there were a lot of police officers sent to search the mountain, and one hostage was rescued in the end, and the others disappeared, just like disappearing from the world."
"So these days, Bureau Qin is also holding meetings every day, and has been urging to find the whereabouts of He Xu and Zhang Fan."
After a pause, Gao Chuanfeng said again: "So, you have to speed up the progress of the case. Bureau Qin still has great hopes for your side."
"If you have a breakthrough here, then our eucalyptus will be fully revitalized. Therefore, Bureau Qin has also issued an order to let all our departments actively cooperate with your criminal investigation team of Furong Branch."
"I know." Hearing Gao Chuanfeng's words, Gu Chen was not surprised at all.
After all, Zhao Guozhi had issued a military order in front of Qin Gang.
Now the pressure is naturally on my side.
Due to the particularity of He Xu and Zhang Fan's identities, as well as the dens destroyed in Shanlan Town last time and the important evidence collected, Qin Gang was greatly surprised.
"Apricot"
Therefore, Qin Gang's focus during this time will naturally be on this end.
But the strange thing is that according to Gao Chuanfeng, the matter that Qin Gang attaches great importance to is on Zhao Guozhi's side, and he didn't hear any urging.
Of course, Gu Chen also knew very well that Zhao Guozhi took all the firepower, so he didn't urge himself.
The purpose is to avoid too much pressure on yourself, which will affect the efficiency of handling cases.
Zhao Guozhi has always been like this, fully trusting himself, so Gu Chen feels that the investigation work on his side also needs to be further accelerated.
Patting Gao Chuanfeng on the shoulder, Gu Chen also understood: "I know, I have also issued a military order here, and I must break it as soon as possible, and I will do it myself."
"That's good." Seeing that Gu Chen is in good condition, Gao Chuanfeng also warned: "I'll help you test the things you want immediately when I go back. If there are results, I will notify you as soon as possible."
"Okay, then I will trouble you." Gu Chen said.
After the two briefly explained a few words, Gao Chuanfeng got into the car and drove away from the Wangchao Town Police Station.
At this very moment, Zhang Wenxia happened to be walking over from the office area. Seeing the city bureau's vehicles leaving, she asked Gu Chen curiously, "They left?"
"Yeah." Gu Chen nodded silently.
"Oh, I didn't even ask them to drink water, so I left?" Zhang Wenxia looked a little disappointed because she also didn't see her colleagues from the Municipal Bureau.
But police officer Wang hurriedly asked Zhang Wenxia: "By the way, Zhang Wenxia, how is your contact going?"
"Ham, I have contacted the village cadres in the surrounding villages and asked them to go to the village to ask about the situation."
"As far as the current feedback is concerned, it seems that they don't know the specific identity of the wild grave."
"But in one village, the village cadre told me that when he went down to inquire about the situation, an old lady said that she seemed to know about the wild grave."
"Really?" Hearing what Zhang Wenxia said, Lu Weiwei was also very curious, and hurriedly asked, "Then...then now..."
"Now the village cadre has already driven the old lady here, and he will probably be here soon."
Here too Zhang Wenxia had just finished speaking, when a car stopped at the gate of the police station.
Zhang Wenxia slapped her thigh, pointed at the door and said, "Hey, maybe it's them."
"Officer Zhang." A middle-aged man walked into the office area with a white-haired old lady familiarly.
Seeing that everyone was there, and there were still some unfamiliar faces, the middle-aged man walked up to Zhang Wenxia and said, "I have already brought the person, what is the specific situation, you can ask her?"
"Old lady?" Seeing the white-haired old lady walking behind the middle-aged man, it was the old lady who gave her cucumber to eat. Lu Weiwei couldn't help but be taken aback: "So it's you?"
"Eh? Little girl?" The old lady glanced at Gu Chen who was beside Lu Weiwei, and said, "Young man, are you there?"
"Yes old lady, we meet again." Seeing this energetic old lady, Gu Chen also smiled politely.
Police officer Wang was very curious, and quickly asked Gu Chen, "Do you know each other?"
"She's the old lady who gave us cucumbers. When you and Xiao Yuan were walking back, didn't you just pass her by?" Lu Weiwei hurriedly reminded her.
On the other side, Yuan Shasha also suddenly realized: "Yes, we have seen it too."
"Old lady, sit down." Seeing that the old lady is the important clue provider, Gu Chen quickly supported the old lady and sat on a seat, and then hurriedly asked her:
"Old lady, do you know that there is a wild grave on that mountain?"
"That's right." The old lady nodded silently, and said slowly, "That wild grave must have existed for about 15 years."
"It has existed for 15 years? Such a long time?" Yuan Shasha couldn't help being taken aback when she heard what the old lady said.
The old lady nodded silently: "Yes, that wild grave is also very strange, but few people should know about it now."
"If our village chief hadn't found me to inquire about it, I would have almost forgotten about it."
Seeing that the old lady really knew something, everyone immediately gathered around.
"Old lady, drink a glass of water." Zhang Wenxia politely handed a cup of freshly brewed tea to the rough hand of the old lady.
"Thank you." The old lady nodded silently, took a small sip, and then said:
"So, what do you want to know from my old woman?"
"We want to know who is buried in that wild grave?" Gu Chen said.
"An outsider?" The old lady raised her head to recall, and said involuntarily, "I remember that there should be an outsider buried in that wild grave."
"Also, that person seems to have died a terrible death. It's hard to confirm his identity. Some people say that he was a beggar. Anyway, there are different opinions, and we can't figure it out."
"A beggar?" Lu Weiwei was taken aback when she heard the old lady's words, and hurriedly asked, "Why is it a beggar?"
"Well, that's how it's called anyway?" The old lady drank her tea and said in retrospect: "It's the kind of person who asks for money on the street, with an erhu in his hand, walks to the door of your store, and randomly plays Next. Then I will ask you for money."
"If you don't give it, he will keep pulling and pulling. If there are some businessmen who are afraid of affecting the mood of customers in the store, they will give a little. This is probably the case."
"So that's the case?" Yuan Shasha also understood after hearing what the old lady said, so she asked the old lady again:
"So old lady, this person is a foreigner, right?"
"Yes, it should be a foreign accent, I have seen it before." The old lady said.
"Then what happened afterwards?" Gu Chen hurriedly asked again.
"Later? Later, I heard that this person huddled in a warehouse to sleep at night, but the warehouse suddenly caught fire. That poor man was engulfed by the fire and burned alive."
Speaking of this, the old lady also looked distressed, and couldn't help frowning.
At this time, Zhang Wenxia also nodded silently, and echoed: "15 years ago, there was indeed a fire in Wangchao Town, but I was not here at that time, and I don't know the specific situation here."
"I understand." As soon as Zhang Wenxia finished speaking, the old lady continued:
"I remember that it was a sponge factory that was burning. Oh, the sponges are flammable. Once they burn, there is no way to put them out."
"Anyway, it feels like there was thick smoke billowing around the sponge factory that night. Many people participated in fighting the fire, but they couldn't fight the fire."
"After counting all the personnel, the owner of the sponge factory was sure that everyone was safe and sound, so he was relieved."
"It feels like the sponge is burning, so let's burn it, at least people are fine."
With a faint sigh, the old lady continued to recall: "Later, the fire brigade also came, but the fire has been burning for a long time, and there are ruins everywhere."
"It was only when everyone cleaned up the scene that they discovered that there was still a body that had been burned beyond recognition, just like a coke."
Speaking of this, the old lady couldn't help shivering, as if thinking about this situation, she felt her hairs stand on end.
"Then what happened later? How to deal with this matter?" Officer Wang asked.
The old lady took a sip of tea, frowned and said, "Later? Later, I remembered that the police from Wangchao Town also came to dispose of the corpse and asked who knew them? They wanted to identify the deceased."
"But everyone said they didn't know each other. After all, it's a coke that's beyond recognition. It's scary to look at."
"And the owner of the sponge factory was also arrested because people were burned to death in the factory, but the owner of the sponge factory bluntly denied that this was an employee of his factory."
"Moreover, the owner of the sponge factory seriously suspected that this person sneaked into his factory at night and set fire to the sponge, which caused the fire."
"After all, it's so good, how can it catch fire?"
After a pause, the old lady looked up at the ceiling and continued to think:
"Anyway, that year, I remember that no one recognized the deceased, and the owner of the sponge factory also confirmed the number of his employees and fully explained his situation."
"So, the police here can only put this case on hold temporarily, and use it as a fire caused by an unknown fire source for the time being."
"Then... this round of corpses." Lu Weiwei also continued to remind.
The old lady nodded: "The corpse has to be dealt with, because this person was originally a loner, and he may have come from other places to make money in the form of playing erhu for money."
"So, no one knows his identity, especially his erhu, which was burned to charcoal along with the fire that night."
With a heavy sigh, the old lady said again: "So at that time, how to deal with the corpse became a problem."
"Because of the special status, the relatives of the deceased could not be found for the time being, so several old policemen who have not retired here made a plan and asked everyone to temporarily bury the body nearby."
"When the relatives of the deceased come to the door, we can give an explanation and take the body away."
"But this waiting has been going on year after year, for fifteen years, and no one has come to pick up the corpse for fifteen years."
"And because of the surrounding villages, the big guys don't agree to bury the corpse in their village cemetery."
"So we came and went again and again, and everyone compromised, and we discussed to bury the body on the mountain."
"Just like that, a few older enthusiastic villagers buried the corpse there together."
"Since no one came to sweep the grave, the grave is probably covered by weeds long ago, and few people know the exact location."
"Yes." Hearing what the old lady said, Lu Weiwei hurriedly replied: "We have been near the wild grave, and the surrounding weeds have been cleaned up, and it feels like all kinds of weeds are piled up high."
"It can be seen how many years it has been since no one came to sweep the tomb and fill the soil? Just recently, this deceased named Yuan Jialiang came to the mountain for 10 consecutive days to worship him."
"I guess, this Yuan Jialiang is a relative of the deceased."
"But how did he know the specific location of the wild grave?" Gu Chen raised his own doubts and said involuntarily:
"After all, he is a provincial, and it is very strange that he can accurately find the location of the tomb."
"He can do things that many local people can't do."
"Also, according to Zhou Zheng, who lives in seclusion on the mountain, he has lived on this mountain for so long, and he has visited almost every corner of the mountain, but he has not noticed this wild grave."
"If Yuan Jialiang hadn't gone up the mountain to offer sacrifices and met Zhou Zheng, Zhou Zheng probably didn't know that there was a wild grave on this mountain."
"Yes." As soon as Gu Chen's voice came here, Lu Weiwei also agreed:
"Junior Brother Gu is right. I don't believe that no one gave Yuan Jialiang directions."
"Or, this Yuan Jialiang may have known the exact location of the tomb back then, but he hadn't been here for many years, and now he suddenly remembered this and came to worship again."
"Or, this fire was set by Yuan Jialiang back then, and it happened to burn to death this unidentified deceased. Out of guilt, he chose to come here to worship?"
Lu Weiwei said a lot about herself in one breath.
Gu Chen also snapped his fingers and said, "What Senior Sister Lu said makes sense, it's entirely possible."
Taking a deep breath, Gu Chen continued to explain to everyone:
"Think about it, everyone. This Yuan Jialiang came to Wangchao Town from Hubei Province. After booking a hotel, he opened it for more than ten days."
"If you want to say that he and those two Guangdong provinces who do channel e-commerce are all here to participate in the Wangchao Town Blueberry Picking Festival, I don't think so."
"After all, Yuan Jialiang doesn't seem to care much about the blueberry picking festival. From the first day he came to Wangchao Town, he started to go out early and return late to sacrifice to the deceased on the mountain."
"It can be seen that Yuan Jialiang's purpose is very clear, and he also knows the specific location of the tomb."
With arms crossed, Gu Chen also leaned on the seat, and continued:
"It can be seen from this that if there is no one to guide Yuan Jialiang, Yuan Jialiang can accurately find the right position."
"This further shows that Yuan Jialiang may have known the specific location of the tomb back then, or it may be like what Senior Sister Lu analyzed just now, this Yuan Jialiang may be an arsonist."
"Because I felt guilty for burning the deceased, so I came here to sacrifice, so that I can feel better."
"Hmm." Listening to Gu Chen's analysis, Police Officer Wang also added with his right index finger:
"There is another possibility, that is, this Yuan Jialiang is related to the deceased. He learned about the specific location of the wild grave through others, so he made a special trip to find it."
"The purpose is clear. He just came to worship the deceased, which shows the importance of the deceased to Yuan Jialiang. After all, he has been offering sacrifices for 10 consecutive days."
"If this Yuan Jialiang hadn't been killed on the mountain because of being poisoned, I guess he would continue to sacrifice."
"What the hell is this person doing?" Also listening to Police Officer Wang's explanation, Lu Weiwei felt that the situation seemed to be getting more and more complicated.
Gu Chen patted his thighs with both hands, stood up, walked back and forth in front of the crowd, and said analytically:
"Now there are two conclusions. One is that Yuan Jialiang was the culprit in the fire at the sponge factory, but because he burned the unidentified deceased to death, he has always felt guilty."
"But when he was buried that year, he knew the specific location, but after leaving here, he never came back."
"And then, because of the condemnation of his conscience, he felt a little guilty, so he chose to come here to worship and sweep the graves of the dead every day."
"As for the other one, Yuan Jialiang is a relative of the deceased, but because the bones have already been charred, it is impossible to judge. Therefore, he can only sacrifice every day for peace of mind."
...
Everyone also expressed their opinions on the identity of Yuan Jialiang and the deceased.
Soon, everyone reached a unified opinion from their differences, and then from a unified opinion to a disagreement, and then unified, and then disagreed...
After a heated argument, Gu Chen also said loudly: "Everyone be quiet."
Seeing Gu Chen speak, everyone also looked at Gu Chen.
"Junior Brother Gu, do you have an idea?" Lu Weiwei asked.
Gu Chen nodded silently: "You can compare this charred corpse with the deceased Yuan Jialiang."
"But it will be more difficult to detect, after all, this is a charred body and the other is also a cold body."
"I think there may be some breakthroughs between the two, but... because of the long time, it is estimated that it will be difficult to come to a result."
In the end, even Gu Chen lost confidence, and his tone became hesitant.
But Zhang Wenxia said indifferently: "It doesn't matter, I believe that the detection technology of the Municipal Bureau should have its own magic weapon."
"If it can be detected successfully, it will also be a major breakthrough for our profession."
"Yes." Gu Chen completely agreed with Zhang Wenxia's statement, and also reminded:
"So, Senior Sister Zhang, can we dig up that wild grave? Then extract relevant substances and conduct identification with Yuan Jialiang's body? See if there is any connection between the two."
"Uh." Seeing Gu Chen's attention on the wild grave again, Zhang Wenxia said with some uncertainty:
"Gu Chen, this corpse is already charred, and it's been 15 years, so... can this still be identified?"
"Don't worry about this." Seeing that Zhang Wenxia had concerns, Gu Chen also reminded: "It is possible to do it with a high probability."
"Higher temperature, organic solvents, acid-base reagents, urea, amides, etc., can all cause denaturation of DNA molecules."
"That is, the hydrogen bonds between the DNA double-stranded bases are broken, and the double helix structure is untied, which is also called DNA unwinding.
After a pause, Gu Chen said again: "But the fracture doesn't mean disappearing. Only when concentrated sulfuric acid can dehydrate and carbonize organic matter can it be said that DNA can be destroyed."
"As far as the incinerated corpse is concerned, it depends on how high the high temperature is? If it is based on the high temperature in the general sense of the human body, the DNA at this temperature is indeed mainly unrotated and denatured."
"Afterwards, under certain conditions, it can be rotated again after cooling down. These are also two important steps in PCR technology."
"PCR technology?" Zhang Wenxia didn't know what these majors belonged to, so she asked Gu Chen weakly:
"Gu Chen, what is this PCR technology?"
"PCR, the full name is polymerase chain reaction." Seeing that Zhang Wenxia didn't understand it, neither did the others present.
Gu Chen simply explained: "It is a molecular biology technique that uses the principle of DNA double-strand replication to amplify a large number of specific DNA fragments outside the body."
"The characteristic is...it can use a small amount of DNA as a template to rapidly amplify and obtain a large number of copies."
"Like the current PCR technology, it has been used in many fields of modern biology and related sciences. It is also widely used in molecular biology and can be used in many fields including biomedical research, criminal forensics and molecular archaeology. "
...
In view of the dead body in the room, Gu Chen did not dare to neglect, so he quickly contacted the Wangchao Town Police Station and asked Zhang Wenxia to transfer all the police officers who could be transferred to the scene of the accident. On his side, after controlling Zhou Zheng, he continued to come to the door. Seeing that the door lock was intact, but it was the simplest lock cylinder, Gu Chen immediately felt that anyone who was good at picking locks could basically pry it open. Therefore, the door of Zhou Zheng's room is almost useless to this kind of people. But after all, Zhou Zheng himself said that he just saw Yuan Jialiang passing by his residence early in the morning, and then walking towards the mountain. Obviously, according to what Zhou Zheng said, the two hadn't met each other this morning. But even so, Yuan Jialiang died in Zhou Zheng's room, which made Gu Chen feel that the murderer seemed extraordinarily arrogant. He even knew that Zhou Zheng was not at home. Turning his head to look at Zhou Zheng who was trembling behind him, Gu Chen asked again: "When you saw this man going up the mountain today, what time was it?" "About...around 9 o'clock?" Zhou Zheng said. "Then what time did you leave the room and go down the mountain?" Gu Chen asked again. "It's...it's like 9:30." Zhou Zheng also said in retrospect. "9:30?" Lu Weiwei was muttering, and she couldn't help but say: "That is to say, after 9:30, you went down the mountain, and you didn't meet anyone after that? Until you met us when you came back?" "Yes." Zhou Zheng was also quite frightened at the moment, and he quickly nodded and admitted: "I went down the mountain around 9:30, and went to the vegetable field at the foot of the mountain." "Anyway, I didn't meet anyone else along the way. I only met you when I came back." "However, I really don't know why this person is in my residence? My room? I obviously have a locked door." "Haven't the windows around you been opened?" Yuan Shasha also asked. Zhou Zheng shook his head: "All are closed and locked from the inside." "Although some ventilation windows are open, they are all fixed with steel bars to prevent theft, and people can't get in at all." According to Zhou Zheng, Lu Weiwei also confirmed it again, and then returned to Gu Chen, confirming: "He is right. The windows in the room do have steel anti-theft guardrails." "I said, I really don't know why this person died in my room?" Zhou Zheng felt wronged, but after thinking about it, he said quickly: "Maybe, maybe this person came here with the murderer after I left, but they saw that the door was locked, so they broke open the door by themselves, went into the room to rest, and then..." Looking up at Gu Chen, Zhou Zheng also guessed and said: "Then, he had a conflict with the murderer, was killed by the murderer in the room, and then the murderer escaped." "But this person was obviously poisoned to death." Lu Weiwei also reminded. "However, none of the tableware here seems to have been touched." Zhou Zheng also reminded. Yuan Shasha also nodded silently: "That's right, I have checked the kitchen, the tableware is neatly arranged, and there is no sign of being tampered with." "Of course, it does not rule out that the murderer washed the tableware after poisoning the deceased, or took the tableware with the poison with him." "Zhou Zheng." As soon as Yuan Shasha finished speaking, Gu Chen reminded, "Come with me to the kitchen." "Okay." Zhou Zheng didn't dare to refute now, he could only stand up obediently, and hurriedly followed behind Gu Chen. Everyone came to the kitchen together, Gu Chen stepped aside and continued to remind, "Check your kitchen and focus on what items are missing?" "Wait a minute." Hearing Gu Chen's remarks, Zhou Zheng squinted his eyes and began to investigate. However, after a while, Zhou Zheng shook his head: "Comrade policeman, all the tableware is here. I don't have a few tableware in the kitchen, anyway, that's all there is." "Collect all these things." Gu Chen also reminded. Fortunately, Yuan Shasha carried some transparent evidence collection bags in her carry-on bag. So all the tableware and cups were wrapped in transparent evidence collection bags, numbered, and photographed for evidence collection. Gu Chen reminded Zhou Zhengdao: "We will bring these things to the Technology Bureau of the Municipal Bureau later to test the residual substances." "Yes." As soon as Gu Chen finished speaking, Zhou Zheng bowed his head and readily agreed. Zhou Zheng spared no effort to cooperate with the police wherever he could. I feel that as long as I can get rid of my suspicions, I must go all out. Since it takes time to wait for support, Police Officer Wang and Yuan Shasha stayed here to protect the scene after sending Zhang Wenxia a specific location. And sent Gu Chen and Lu Weiwei, together with Zhou Zheng, to the wild grave on the mountain to check the situation. The three of them walked for about half an hour, when Zhou Zheng suddenly stopped, pointed to a square in front of him and said, "The wild grave is over there." Gu Chen and Lu Weiwei took a step forward, and there was an open space between the mountains, where a raised hill appeared. At first glance, it is just a raised hill, but the surrounding weeds seem to have been cleaned up. From this point of view, it does look like the prototype of a tomb. "How can you tell that this is a wild grave?" Gu Chen asked Zhou Zheng. Zhou Zheng waved his hand: "I didn't know at first, but I also heard from that person later. He said that the purpose of his going up the mountain was also to come to worship." "But I'm very puzzled. Since he came from such a long distance, and he came here to worship for several days in a row, it feels quite strange." "Besides, he has so many days, why doesn't he erect a stone tablet for this wild grave?" Also listening to Zhou Zheng's words, Gu Chen and Lu Weiwei walked slowly to the so-called wild grave. At this time, the weeds around the "wild grave" were completely cleared, not only that, even the weeds on the top of the wild grave were also cleared, and some new soil was filled in. Gu Chen was puzzled, but also shook his head: "It's too weird, what does this Yuan Jialiang mean? He has been to Jiangnan City before?" "How did he know that there is a wild grave on this mountain? Who is buried in the wild grave?" "I don't know." Zhou Zheng walked up to Gu Chen and also explained: "I've lived on the mountain for so long, and I've never heard of it. That's this, this man named Yuan Jialiang. After he came, I realized that this is a wild grave. I didn't know it at all before. Notice." "Wait for the colleagues from Wangchao Town Police Station to come to support and confirm the situation here." Gu Chen said. "En." Lu Weiwei nodded silently, then looked around, also curiously said: "You said, this Yuan Jialiang, who comes here every day, just walks around the wild grave on this mountain? It can't be that simple, can it?" "And he leaves early and returns late every day, for 10 consecutive days. Is he crazy?" "How do I know that?" Zhou Zheng shook his head. But Lu Weiwei said unhappily: "You said that you are a hermit, and you have stayed on the mountain for so long. For this kind of sudden visit from the provinces, you don't want to know more about him?" "Comrade policeman." Seeing that Lu Weiwei made her way to the end, Zhou Zheng was also speechless and said: "I came here because I wanted to be quiet. I don't like places that are too lively, really." "So what if there are people coming up the mountain? Anyway, there will be some people coming up the mountain one after another, but not many." "I don't want to get involved in these people's affairs, but I don't like these people to disturb me very much. I just want to be quiet." "Okay." Seeing that Zhou Zheng was also depressed at the moment, Gu Chen didn't make things difficult for him for the time being, and reminded him: "We will send all the tableware in your kitchen to the technical department of the Municipal Bureau for inspection. I hope no residual toxic substances are detected, otherwise you'd better give me a reasonable explanation." "Yes, yes, yes." It feels like this kind of thing is going to happen, and he can only accept his fate, so Zhou Zheng is also breaking his cans now. After several people checked around the wild tomb, they returned to the ancient temple. At this moment, Zhang Wenxia has brought two police officers and several enthusiastic people to the scene. Just in time to meet Gu Chen who came down from the mountain. Zhang Wenxia also hurried forward to say hello: "Gu Chen, I have already brought the person you want, and I am afraid that there will not be enough manpower, so I called some enthusiastic people over." "Have you brought anything?" Gu Chen asked. "Is this okay? I borrowed a stretcher from the health center." Zhang Wenxia gave up a seat, and an enthusiastic crowd immediately put the folding stretcher in front of her. "Yes." Lu Weiwei nodded silently. Zhang Wenxia said again: "I have already brought the cloth for wrapping the corpse. This place has inconvenient transportation, so we can only use a stretcher to transport the corpse out, and then take the railway." Before Zhang Wenxia finished speaking, Police Officer Wang had already walked out of the house. Seeing Zhang Wenxia too, Police Officer Wang quickly asked her, "Zhang Wenxia, what happened to the wild grave on the mountain? Was there a corpse buried here?" "Uh" Hearing Officer Wang's words, Zhang Wenxia froze for a moment, then shook her head: "This... I don't know very well." "Maybe." As soon as Zhang Wenxia finished speaking, an enthusiastic crowd behind him answered, "I heard from the older generation that an unknown corpse was once buried on the mountain here." "Because it's been a long time, few people know about it, and it's not clear who the corpse is. So no one erected an inscription or anything like that." "Then do you know anything else about this wild grave?" Seeing that the enthusiastic crowd seemed to understand something, Gu Chen quickly asked again. The enthusiastic crowd shook their heads: "I don't know about the others. I also heard from my grandparents. As for where is the wild grave? Actually, I don't know. After all, the wild grave has been there for many years." "It is estimated that the grass on the head of the grave has already covered the wild grave. My friends and I have come here to play a few times, and we have also been to the top of the mountain, but we have never found the location of the wild grave." "That's right." Just as the man here finished speaking, another fat and enthusiastic crowd quickly echoed: "I've been to this mountain several times, but I haven't seen any wild graves? I just heard about it." "That's strange." Hearing what the two said, Gu Chen frowned slightly, and said in wonder: "You local people don't know much about the situation of this wild grave, and you can't even find out the specific location of this wild grave." "But Yuan Jialiang, an outsider, was able to find it accurately, and even helped clear the weeds in this wild grave. What is he doing?" "Or, the people buried in this wild grave may be his relatives?" "This...is very possible." Hearing what Gu Chen said, Police Officer Wang also felt that the grave was a bit strange. Thinking of Gu Chen and Lu Weiwei, who had just come down from the mountain, Police Officer Wang hurriedly asked Gu Chen again: "By the way, Gu Chen, you and Lu Weiwei came down from there just now, what's going on there?" "All the weeds around the field grave were removed, maybe this Yuan Jialiang did it?" Gu Chen said. Officer Wang flicked his right index finger: "That is to say, this Yuan Jialiang came to this mountain these days just to visit this wild grave?" "However, how can he know the exact location of the wild grave?" "Perhaps, someone told him." Gu Chen also speculated. Everyone stood at the door and talked for a while, and then they took everyone to the room, wrapped Yuan Jialiang's body in cloth and tied it tightly, and then carried the body onto a stretcher. Afterwards, two police officers saw the scene and sealed it off, and Gu Chen also completed all the photos and evidence collection. Due to the need to find out the specific situation as soon as possible, especially the origin of the wild grave, Gu Chen walked up to Zhang Wenxia and whispered: "Senior Sister Zhang, can this wild grave be excavated to see who you are?" "this" Hearing what Gu Chen said, Zhang Wenxia suddenly trembled: "This...isn't that good? After all, it's disrespectful to the dead." "Although I don't know the specific identity of this person, but I always feel..." "However, if this wild tomb is not excavated, it will be impossible to confirm the specific identity of the people buried in the wild tomb." "So it is impossible to confirm what kind of relationship this person has with Yuan Jialiang?" Before Zhang Wenxia finished speaking, Gu Chen also expressed his thoughts. Zhang Wenxia nodded silently: "I know, for your criminal investigation team, this is an important clue." "Or, I'll contact the village cadres in the nearby villages first. If none of them claim it, then you can definitely lead someone to dig out the wild graves and bring the corpses back for testing." "After all, it is unclaimed and complies with the regulations. What do you think?" "Then I'll have to thank Senior Sister Zhang." Seeing that Zhang Wenxia also gave the best solution, Gu Chen was naturally relieved. Subsequently, two police officers stayed at the scene of the accident to deal with follow-up matters. Gu Chen, Lu Weiwei, Police Officer Wang and Yuan Shasha, together with Zhang Wenxia, carried Yuan Jialiang's body down the mountain with the help of several enthusiastic people. And Zhou Zheng, who also followed Gu Chen and the others down the mountain, will also return to Wangchao Town Police Station with everyone for further investigation. ... ... It was already 3 p.m. when we returned to the Wangchao Town Police Station. So under Zhang Wenxia's arrangement, everyone ate some light meals. Due to the small scale of the Wangchao Town Police Station, the number of police officers is also very small. A few years ago, when the population was small, it was set up as a police office. In recent years, due to the good agricultural development, green enterprises have begun to take root in Wangchao Town. Wangchao Town has just changed from population outflow to population inflow. But even so, there are only five police officers in the entire Wangchao Town Police Station. In the future, according to the population size, the police force will be gradually increased according to the situation. However, after Gu Chen called for support, at around 3:10 in the afternoon, Gao Chuanfeng's team from the Technical Section of the Municipal Bureau also drove to the gate of the Wangchao Town Police Station. "Gu Chen." Gao Chuanfeng got out of the car and walked towards Gu Chen. The two forensic assistants beside him also brought related accessories. Including body bags and other materials. Gu Chen put down the empty lunch box he had just finished eating, pointed to the stretcher on the ground and said, "He is here, and it is preliminarily inferred that he died of poisoning. You should take it back for testing first." "In addition, we still have some packaged tableware here. You can also take it back for testing. If you have any results, please notify us immediately." "Eat so late?" Listening to Gu Chen's introduction, Gao Chuanfeng walked up to Yuan Jialiang's body, opened the shroud, and started on-site inspection. Several forensic assistants also surrounded him. On the other hand, Zhang Wenxia is still actively contacting the nearby village cadres, repeatedly confirming the identity of the wild graves on the mountain. As for Zhou Zheng, because the place where Yuan Jialiang died was Zhou Zheng's bedroom, Zhou Zheng was temporarily detained here for further interrogation. After completing the preliminary inspection, Gao Chuanfeng asked two assistants to put the body into a body bag, hand over the other items by the way, and take them into the car together. When he came to Gu Chen, Gao Chuanfeng said again: "Gu Chen, I heard that Bureau Qin is still angry about the matter in Wangxian Valley. The whereabouts of He Xu and Zhang Fan's criminal gang are unknown, which makes Bureau Qin very confused. fire." "After all, there were a lot of police officers sent to search the mountain, and one hostage was rescued in the end, and the others disappeared, just like disappearing from the world." "So these days, Bureau Qin is also holding meetings every day, and has been urging to find the whereabouts of He Xu and Zhang Fan." After a pause, Gao Chuanfeng said again: "So, you have to speed up the progress of the case. Bureau Qin still has great hopes for your side." "If you have a breakthrough here, then our eucalyptus will be fully revitalized. Therefore, Bureau Qin has also issued an order to let all our departments actively cooperate with your criminal investigation team of Furong Branch." "I know." Hearing Gao Chuanfeng's words, Gu Chen was not surprised at all. After all, Zhao Guozhi had issued a military order in front of Qin Gang. Now the pressure is naturally on my side. Due to the particularity of He Xu and Zhang Fan's identities, as well as the dens destroyed in Shanlan Town last time and the important evidence collected, Qin Gang was greatly surprised. "Apricot" Therefore, Qin Gang's focus during this time will naturally be on this end. But the strange thing is that according to Gao Chuanfeng, the matter that Qin Gang attaches great importance to is on Zhao Guozhi's side, and he didn't hear any urging. Of course, Gu Chen also knew very well that Zhao Guozhi took all the firepower, so he didn't urge himself. The purpose is to avoid too much pressure on yourself, which will affect the efficiency of handling cases. Zhao Guozhi has always been like this, fully trusting himself, so Gu Chen feels that the investigation work on his side also needs to be further accelerated. Patting Gao Chuanfeng on the shoulder, Gu Chen also understood: "I know, I have also issued a military order here, and I must break it as soon as possible, and I will do it myself." "That's good." Seeing that Gu Chen is in good condition, Gao Chuanfeng also warned: "I'll help you test the things you want immediately when I go back. If there are results, I will notify you as soon as possible." "Okay, then I will trouble you." Gu Chen said. After the two briefly explained a few words, Gao Chuanfeng got into the car and drove away from the Wangchao Town Police Station. At this very moment, Zhang Wenxia happened to be walking over from the office area. Seeing the city bureau's vehicles leaving, she asked Gu Chen curiously, "They left?" "Yeah." Gu Chen nodded silently. "Oh, I didn't even ask them to drink water, so I left?" Zhang Wenxia looked a little disappointed because she also didn't see her colleagues from the Municipal Bureau. But police officer Wang hurriedly asked Zhang Wenxia: "By the way, Zhang Wenxia, how is your contact going?" "Ham, I have contacted the village cadres in the surrounding villages and asked them to go to the village to ask about the situation." "As far as the current feedback is concerned, it seems that they don't know the specific identity of the wild grave." "But in one village, the village cadre told me that when he went down to inquire about the situation, an old lady said that she seemed to know about the wild grave." "Really?" Hearing what Zhang Wenxia said, Lu Weiwei was also very curious, and hurriedly asked, "Then...then now..." "Now the village cadre has already driven the old lady here, and he will probably be here soon." Here too Zhang Wenxia had just finished speaking, when a car stopped at the gate of the police station. Zhang Wenxia slapped her thigh, pointed at the door and said, "Hey, maybe it's them." "Officer Zhang." A middle-aged man walked into the office area with a white-haired old lady familiarly. Seeing that everyone was there, and there were still some unfamiliar faces, the middle-aged man walked up to Zhang Wenxia and said, "I have already brought the person, what is the specific situation, you can ask her?" "Old lady?" Seeing the white-haired old lady walking behind the middle-aged man, it was the old lady who gave her cucumber to eat. Lu Weiwei couldn't help but be taken aback: "So it's you?" "Eh? Little girl?" The old lady glanced at Gu Chen who was beside Lu Weiwei, and said, "Young man, are you there?" "Yes old lady, we meet again." Seeing this energetic old lady, Gu Chen also smiled politely. Police officer Wang was very curious, and quickly asked Gu Chen, "Do you know each other?" "She's the old lady who gave us cucumbers. When you and Xiao Yuan were walking back, didn't you just pass her by?" Lu Weiwei hurriedly reminded her. On the other side, Yuan Shasha also suddenly realized: "Yes, we have seen it too." "Old lady, sit down." Seeing that the old lady is the important clue provider, Gu Chen quickly supported the old lady and sat on a seat, and then hurriedly asked her: "Old lady, do you know that there is a wild grave on that mountain?" "That's right." The old lady nodded silently, and said slowly, "That wild grave must have existed for about 15 years." "It has existed for 15 years? Such a long time?" Yuan Shasha couldn't help being taken aback when she heard what the old lady said. The old lady nodded silently: "Yes, that wild grave is also very strange, but few people should know about it now." "If our village chief hadn't found me to inquire about it, I would have almost forgotten about it." Seeing that the old lady really knew something, everyone immediately gathered around. "Old lady, drink a glass of water." Zhang Wenxia politely handed a cup of freshly brewed tea to the rough hand of the old lady. "Thank you." The old lady nodded silently, took a small sip, and then said: "So, what do you want to know from my old woman?" "We want to know who is buried in that wild grave?" Gu Chen said. "An outsider?" The old lady raised her head to recall, and said involuntarily, "I remember that there should be an outsider buried in that wild grave." "Also, that person seems to have died a terrible death. It's hard to confirm his identity. Some people say that he was a beggar. Anyway, there are different opinions, and we can't figure it out." "A beggar?" Lu Weiwei was taken aback when she heard the old lady's words, and hurriedly asked, "Why is it a beggar?" "Well, that's how it's called anyway?" The old lady drank her tea and said in retrospect: "It's the kind of person who asks for money on the street, with an erhu in his hand, walks to the door of your store, and randomly plays Next. Then I will ask you for money." "If you don't give it, he will keep pulling and pulling. If there are some businessmen who are afraid of affecting the mood of customers in the store, they will give a little. This is probably the case." "So that's the case?" Yuan Shasha also understood after hearing what the old lady said, so she asked the old lady again: "So old lady, this person is a foreigner, right?" "Yes, it should be a foreign accent, I have seen it before." The old lady said. "Then what happened afterwards?" Gu Chen hurriedly asked again. "Later? Later, I heard that this person huddled in a warehouse to sleep at night, but the warehouse suddenly caught fire. That poor man was engulfed by the fire and burned alive." Speaking of this, the old lady also looked distressed, and couldn't help frowning. At this time, Zhang Wenxia also nodded silently, and echoed: "15 years ago, there was indeed a fire in Wangchao Town, but I was not here at that time, and I don't know the specific situation here." "I understand." As soon as Zhang Wenxia finished speaking, the old lady continued: "I remember that it was a sponge factory that was burning. Oh, the sponges are flammable. Once they burn, there is no way to put them out." "Anyway, it feels like there was thick smoke billowing around the sponge factory that night. Many people participated in fighting the fire, but they couldn't fight the fire." "After counting all the personnel, the owner of the sponge factory was sure that everyone was safe and sound, so he was relieved." "It feels like the sponge is burning, so let's burn it, at least people are fine." With a faint sigh, the old lady continued to recall: "Later, the fire brigade also came, but the fire has been burning for a long time, and there are ruins everywhere." "It was only when everyone cleaned up the scene that they discovered that there was still a body that had been burned beyond recognition, just like a coke." Speaking of this, the old lady couldn't help shivering, as if thinking about this situation, she felt her hairs stand on end. "Then what happened later? How to deal with this matter?" Officer Wang asked. The old lady took a sip of tea, frowned and said, "Later? Later, I remembered that the police from Wangchao Town also came to dispose of the corpse and asked who knew them? They wanted to identify the deceased." "But everyone said they didn't know each other. After all, it's a coke that's beyond recognition. It's scary to look at." "And the owner of the sponge factory was also arrested because people were burned to death in the factory, but the owner of the sponge factory bluntly denied that this was an employee of his factory." "Moreover, the owner of the sponge factory seriously suspected that this person sneaked into his factory at night and set fire to the sponge, which caused the fire." "After all, it's so good, how can it catch fire?" After a pause, the old lady looked up at the ceiling and continued to think: "Anyway, that year, I remember that no one recognized the deceased, and the owner of the sponge factory also confirmed the number of his employees and fully explained his situation." "So, the police here can only put this case on hold temporarily, and use it as a fire caused by an unknown fire source for the time being." "Then... this round of corpses." Lu Weiwei also continued to remind. The old lady nodded: "The corpse has to be dealt with, because this person was originally a loner, and he may have come from other places to make money in the form of playing erhu for money." "So, no one knows his identity, especially his erhu, which was burned to charcoal along with the fire that night." With a heavy sigh, the old lady said again: "So at that time, how to deal with the corpse became a problem." "Because of the special status, the relatives of the deceased could not be found for the time being, so several old policemen who have not retired here made a plan and asked everyone to temporarily bury the body nearby." "When the relatives of the deceased come to the door, we can give an explanation and take the body away." "But this waiting has been going on year after year, for fifteen years, and no one has come to pick up the corpse for fifteen years." "And because of the surrounding villages, the big guys don't agree to bury the corpse in their village cemetery." "So we came and went again and again, and everyone compromised, and we discussed to bury the body on the mountain." "Just like that, a few older enthusiastic villagers buried the corpse there together." "Since no one came to sweep the grave, the grave is probably covered by weeds long ago, and few people know the exact location." "Yes." Hearing what the old lady said, Lu Weiwei hurriedly replied: "We have been near the wild grave, and the surrounding weeds have been cleaned up, and it feels like all kinds of weeds are piled up high." "It can be seen how many years it has been since no one came to sweep the tomb and fill the soil? Just recently, this deceased named Yuan Jialiang came to the mountain for 10 consecutive days to worship him." "I guess, this Yuan Jialiang is a relative of the deceased." "But how did he know the specific location of the wild grave?" Gu Chen raised his own doubts and said involuntarily: "After all, he is a provincial, and it is very strange that he can accurately find the location of the tomb." "He can do things that many local people can't do." "Also, according to Zhou Zheng, who lives in seclusion on the mountain, he has lived on this mountain for so long, and he has visited almost every corner of the mountain, but he has not noticed this wild grave." "If Yuan Jialiang hadn't gone up the mountain to offer sacrifices and met Zhou Zheng, Zhou Zheng probably didn't know that there was a wild grave on this mountain." "Yes." As soon as Gu Chen's voice came here, Lu Weiwei also agreed: "Junior Brother Gu is right. I don't believe that no one gave Yuan Jialiang directions." "Or, this Yuan Jialiang may have known the exact location of the tomb back then, but he hadn't been here for many years, and now he suddenly remembered this and came to worship again." "Or, this fire was set by Yuan Jialiang back then, and it happened to burn to death this unidentified deceased. Out of guilt, he chose to come here to worship?" Lu Weiwei said a lot about herself in one breath. Gu Chen also snapped his fingers and said, "What Senior Sister Lu said makes sense, it's entirely possible." Taking a deep breath, Gu Chen continued to explain to everyone: "Think about it, everyone. This Yuan Jialiang came to Wangchao Town from Hubei Province. After booking a hotel, he opened it for more than ten days." "If you want to say that he and those two Guangdong provinces who do channel e-commerce are all here to participate in the Wangchao Town Blueberry Picking Festival, I don't think so." "After all, Yuan Jialiang doesn't seem to care much about the blueberry picking festival. From the first day he came to Wangchao Town, he started to go out early and return late to sacrifice to the deceased on the mountain." "It can be seen that Yuan Jialiang's purpose is very clear, and he also knows the specific location of the tomb." With arms crossed, Gu Chen also leaned on the seat, and continued: "It can be seen from this that if there is no one to guide Yuan Jialiang, Yuan Jialiang can accurately find the right position." "This further shows that Yuan Jialiang may have known the specific location of the tomb back then, or it may be like what Senior Sister Lu analyzed just now, this Yuan Jialiang may be an arsonist." "Because I felt guilty for burning the deceased, so I came here to sacrifice, so that I can feel better." "Hmm." Listening to Gu Chen's analysis, Police Officer Wang also added with his right index finger: "There is another possibility, that is, this Yuan Jialiang is related to the deceased. He learned about the specific location of the wild grave through others, so he made a special trip to find it." "The purpose is clear. He just came to worship the deceased, which shows the importance of the deceased to Yuan Jialiang. After all, he has been offering sacrifices for 10 consecutive days." "If this Yuan Jialiang hadn't been killed on the mountain because of being poisoned, I guess he would continue to sacrifice." "What the hell is this person doing?" Also listening to Police Officer Wang's explanation, Lu Weiwei felt that the situation seemed to be getting more and more complicated. Gu Chen patted his thighs with both hands, stood up, walked back and forth in front of the crowd, and said analytically: "Now there are two conclusions. One is that Yuan Jialiang was the culprit in the fire at the sponge factory, but because he burned the unidentified deceased to death, he has always felt guilty." "But when he was buried that year, he knew the specific location, but after leaving here, he never came back." "And then, because of the condemnation of his conscience, he felt a little guilty, so he chose to come here to worship and sweep the graves of the dead every day." "As for the other one, Yuan Jialiang is a relative of the deceased, but because the bones have already been charred, it is impossible to judge. Therefore, he can only sacrifice every day for peace of mind." ... Everyone also expressed their opinions on the identity of Yuan Jialiang and the deceased. Soon, everyone reached a unified opinion from their differences, and then from a unified opinion to a disagreement, and then unified, and then disagreed... After a heated argument, Gu Chen also said loudly: "Everyone be quiet." Seeing Gu Chen speak, everyone also looked at Gu Chen. "Junior Brother Gu, do you have an idea?" Lu Weiwei asked. Gu Chen nodded silently: "You can compare this charred corpse with the deceased Yuan Jialiang." "But it will be more difficult to detect, after all, this is a charred body and the other is also a cold body." "I think there may be some breakthroughs between the two, but... because of the long time, it is estimated that it will be difficult to come to a result." In the end, even Gu Chen lost confidence, and his tone became hesitant. But Zhang Wenxia said indifferently: "It doesn't matter, I believe that the detection technology of the Municipal Bureau should have its own magic weapon." "If it can be detected successfully, it will also be a major breakthrough for our profession." "Yes." Gu Chen completely agreed with Zhang Wenxia's statement, and also reminded: "So, Senior Sister Zhang, can we dig up that wild grave? Then extract relevant substances and conduct identification with Yuan Jialiang's body? See if there is any connection between the two." "Uh." Seeing Gu Chen's attention on the wild grave again, Zhang Wenxia said with some uncertainty: "Gu Chen, this corpse is already charred, and it's been 15 years, so... can this still be identified?" "Don't worry about this." Seeing that Zhang Wenxia had concerns, Gu Chen also reminded: "It is possible to do it with a high probability." "Higher temperature, organic solvents, acid-base reagents, urea, amides, etc., can all cause denaturation of DNA molecules." "That is, the hydrogen bonds between the DNA double-stranded bases are broken, and the double helix structure is untied, which is also called DNA unwinding. After a pause, Gu Chen said again: "But the fracture doesn't mean disappearing. Only when concentrated sulfuric acid can dehydrate and carbonize organic matter can it be said that DNA can be destroyed." "As far as the incinerated corpse is concerned, it depends on how high the high temperature is? If it is based on the high temperature in the general sense of the human body, the DNA at this temperature is indeed mainly unrotated and denatured." "Afterwards, under certain conditions, it can be rotated again after cooling down. These are also two important steps in PCR technology." "PCR technology?" Zhang Wenxia didn't know what these majors belonged to, so she asked Gu Chen weakly: "Gu Chen, what is this PCR technology?" "PCR, the full name is polymerase chain reaction." Seeing that Zhang Wenxia didn't understand it, neither did the others present. Gu Chen simply explained: "It is a molecular biology technique that uses the principle of DNA double-strand replication to amplify a large number of specific DNA fragments outside the body." "The characteristic is...it can use a small amount of DNA as a template to rapidly amplify and obtain a large number of copies." "Like the current PCR technology, it has been used in many fields of modern biology and related sciences. It is also widely used in molecular biology and can be used in many fields including biomedical research, criminal forensics and molecular archaeology. " ...
