Gu Chen put on a pair of new gloves again and pushed the tray beside instructor Zhang Hui to one side. Then he asked, "drillmaster Zhang, what do you mean by abnormality?"
"Look at this." Zhang Hui gives up a body position and gives the position of microscope to Gu Chen.
Gu Chen bows down directly and looks at the microscope for a while. Suddenly, he frowns: "yes Is it pollen? "
"Yes, it's pollen, and it's mixed with bits of clay." Zhang Hui said.
Lu Weiwei was stunned: "so So, this is not the dirt that Wang Jinshan scratched out at all? "
"It's true." Gu Chen took back his eyes and said in surprise: "if Wang Jinshan was swimming in the swimming pool, there would not be so much pollen and soil debris between the nail cracks."
After seeing Lu Weiwei and officer Wang, Gu Chen asked again, "elder martial sister Lu, senior brother Wang, do you remember having dinner with Wang Jinshan yesterday?"
"What do you want to say?" Lu Weiwei seems to have guessed Gu Chen's meaning.
Gu Chen went to Wang Jinshan's body, lifted Wang Jinshan's left hand and asked, "did you find so much dirt on his fingernails yesterday?"
"Absolutely not." Lu Weiwei affirmed: "yesterday at dinner, Wang Jinshan's hands are very clean, absolutely will not appear so much dirt."
"Indeed." Gu Chen put Wang Jinshan's left hand down gently: "I sat by his side yesterday, and his hands really didn't have so much dirt."
"But the problem is, after he and his assistant left yesterday, the assistant can't contact Wang Jinshan today. Until the police call, Wang Jinshan has been floating in the swimming pool."
"It is known that Wang Jinshan died in the early hours of yesterday morning, and he died of drowning. Then what happened during the period when he left the hotel and went home is the key to the investigation."
"Yes." He Wenjun very much agreed with Gu Chen's opinion, but also actively echoed: "if Wang Jinshan has never gone out since he entered his home, it is impossible that there is so much suspicious dirt in the gap between his fingers."
"What's more, we searched Wang Jinshan's house at that time. There were almost no flowers in his house, but some lawns in the yard."
On hearing the speech, officer Wang nodded slightly and said, "if so, where does the pollen come from? It can only explain one truth. This swimming pool may not be the first scene of the crime. "
"It was Wang Jinshan who was drowned in other places, and he didn't even know it Move to the pool at Wang Jinshan's home to create the illusion of accidental drowning. "
After all, it is learning for application
Today's training class, just talked about the relevant knowledge, officer Wang can immediately contact.
Liu Zhiqiang nodded slightly: "that's right. If there are no flowers at home, how can there be pollen debris in the nail seams? The pool at home is definitely not the first scene. "
The scene soon discussed
Gu Chen sat back to the test bench again, observed the pollen material through the microscope, and then turned to ask Zhang Hui: "instructor Zhang, it was a short time from Wang Jinshan to his accidental death."
"If that's the case, then the flower should be growing nearby. Does your lab have an archive of this kind of data?"
"This..." Zhang Hui was stunned and was suddenly asked by Gu Chen. He was embarrassed and said, "there were some pollen data before, but they are not comprehensive."
"If you want to talk about water quality data, we have a lot of data in our laboratory."
"This is no longer the key." Gu Chen stood up directly and said, "this kind of pollen should be the reproductive organ of gymnosperms and angiosperms. It is very small, and its structure can only be seen through a microscope."
"But different plants have different shapes of pollen. According to the shape and size of pollen, symmetry and polarity, the structure of pollen wall and the surface sculpture, it is possible to identify families, genera and species of plants."
Looking at Zhang Hui, Gu Chen added: "most plant pollen is easy to collect. It can be preserved for quite a long time without losing vitality. This plant should be nearby. I want to go over to investigate and collect the flowers nearby to see which ones are specific, so as to judge the location of the crime."
"But Looking for a needle in a haystack
Zhang Huigang wanted to pour cold water on it, but Gu Chen opened the mobile phone map directly. Liang said in front of Zhang Hui: "instructor Zhang, I have already checked. Wang Jinshan's home is backed by a small hillside. There is very little water there. There is only one park pool. I want to go there and have a look. Maybe this is the first scene of the crime."
"You seem to have a point." Hearing Gu Chen's analysis, Zhang Hui nodded silently, then looked at he Wenjun and said, "what do you mean?"
"I think it works." He Wenjun said.
"That's good." Seeing that they had reached a tacit understanding, Zhang Hui took a deep breath and said, "I'll try my best to study this pollen structure to determine which species as soon as possible."
"You go to the park pond first, and you may find some new discoveries. If there are flowers by the pond, collect the specimens."After thinking about it, Zhang Hui said again, "remember to number the flowers and places you picked."
"Yes." Gu Chen nodded slightly, but suddenly remembered that this was the boundary of the Yangcheng police force. He Wenjun was asked in a tone of inquiry: "officer he, I don't know if there is a chance to partner with your criminal investigation team two."
"Of course it can."
Gu Chen asked for a battle, and he Wenjun was certainly willing.
After all, it is the investigation work. The main task needs more people, so more people will have more strength.
What's more, Gu Chen's training class belongs to self-study time in the evening, which does not delay the class, so it is a natural course.
After reaching the cooperation intention, Gu Chen quickly went to the storage cabinet in the detection room and found more small evidence bags. Then he said, "it should not be too late. We will start right now."
……
……
He Wenjun and Liu Zhiqiang, driving with Gu Chen team and many police officers from the second criminal investigation team, rushed to Wang Jinshan's death site.
This area is a mature community, the development time is early, the housing structure is relatively old.
I heard that the police officer who knew the trade said that this place was a villa bought by Wang Jinshan when he just made a fortune.
Of course, later Wang Jinshan also bought more villas, which is also later.
However, since leaving Jiangguan fund and taking care of its own portal, Wang Jinshan has been at a disadvantageous start and the fund has been losing money year after year.
When Wang Jinshan can't hold on, he will choose to sell a suite to ease the huge financial pressure.
If it had not been for the scenery that many people had bought houses in those years, Wang Jinshan today would have fallen.
In addition, the housing price of Yangcheng is extremely high, which also gives Wang Jinshan a buffer opportunity.
It is said that a listed company invested by Wang Jinshan was difficult to operate and close to the verge of bankruptcy.
In order to save the listed company, Wang Jinshan sold a school district house in Yangcheng. Then the company, which was on the verge of bankruptcy, came back from the dead. The profit margin between the purchase and sale of house price exceeded the total profit of the listed company in three years.
On that day, the crisis never existed alone. The poor performance of the funds in his hands made Wang Jinshan's capital less and less.
With one after another selling houses to save the market, almost hollowed out Wang Jinshan's accumulated wealth in these years.
However, because this villa is the first villa that Wang Jinshan earned by working in Jiangguan fund, it is of great significance to Wang Jinshan, so it is well preserved.
Wang Jinshan has always liked to live here.
After learning about the villa from the police, Gu Chen crossed the cordon and entered the pool where Wang Jinshan drowned.
At this moment, the water in the swimming pool seems to be a little muddy. Gu Chen investigates the surrounding monitoring, but finds that there is no monitoring here, so he can't help frowning.
"What's the situation? There's no surveillance around this kind of mansion? " Gu Chen asked he Wenjun.
He Wenjun also hastily explained: "there used to be, but later when we were investigating here, we also asked Wang Jinshan's assistant."
"What he means is that Wang Jinshan doesn't like to set up monitoring in the courtyard, because there are swimming pools in the courtyard. If the monitoring goes wrong, it's easy to expose privacy."
"Therefore, only the road in front of Wang Jinshan's home is monitored at the intersection. Other places, for fear of privacy, have been removed by Wang Jinshan."
"Withdrawn?" After hearing what he Wenjun said, officer Wang did not dare to set up a channel: "although for a financial magnate like him, who will he meet? It's private to talk to someone about cooperation, or to work with someone at home. "
"Moreover, any gossip may affect the trend of his fund, so these people are usually very cautious, and it is not unreasonable to remove the surveillance cameras in the courtyard."
"Yes." A police officer with a Cantonese accent also said: "this is true, especially our Cantonese people are used to speculation in stocks and funds."
"Every big man and senior management of these listed companies must be strict with themselves. Otherwise, a little bit of frivolous news comes out, which will have a bad impact on the company, and the stock price fund will plummet all the way."
"So these big guys, usually pay attention to personal privacy, it is estimated that hackers may invade the monitoring system. This kind of thing has happened before."
"So it is?" On hearing this, officer Wang no longer cares about these things.
It just feels like a double-edged sword
Gu Chen walked along the fence and found two obvious friction marks on a low wall.
After that, I found two marks on the floor.
Looking at Gu Chen's happy face, he Wenjun stepped forward and asked Gu Chen, "officer Gu, do you have any findings?"
"Take a look at this." Gu Chen did not give the answer directly, but gave up a body position, and only showed he Wenjun the four friction marks on the wall and floor tiles.He Wenjun frowned and quickly approached the trace. After repeatedly confirming, he looked at Gu Chen in surprise: "you mean This trace of the ladder
"Yes, and it's new." Gu Chen also responded directly.
Smell speech two people's speech, one side of Lu Weiwei, Wang police officer and Liu Zhiqiang three people, also hastened to come over.
"Is there something new? What ladder? " Lu Weiwei stepped forward to observe Gu Chen. She immediately understood Gu Chen's meaning and said with a smile:
"younger martial brother Gu, what do you mean It is very likely that the murderer used a ladder to climb over the wall and transport Wang Jinshan's body to the swimming pool through this site? "
Gu Chen didn't speak, just nodded slightly.
But standing on the side of Liu Zhiqiang said: "then why not go to the gate?"
He Wenjun knocked on Liu Zhiqiang's head and said, "stupid, go through the gate. Isn't it more troublesome to deal with traces?"
"On the floor, on the door handle, where there is a trace, do you think it is easy to deal with in a short time?"
"Well, that seems to be the case." After Liu Zhiqiang observed the traces near the wall, he suddenly realized: "if you transport the corpse in this place through the ladder, it will save a lot of trouble to clean up the traces."
"After all, the courtyard is not as exquisite as the home, leaving a little trace, it is difficult to be noticed."
Gu Chen smell speech, also slightly nod: "officer Liu said is very reasonable, the reason why the murderer does not go through the door, is also for unnecessary trouble."
"After all, there is a little trace left in the room. In the eyes of the police, it is also infinitely enlarged. The murderer is not so stupid."
Listening to Gu Chen's explanation, Lu Weiwei seemed to understand the truth. She stepped back a few steps. Suddenly, she pushed her right leg backward, her forefoot grasped the ground, and quickly rushed toward the wall.
With the help of this kick, Lu Weiwei easily climbed over the wall, which found that there was a small forest near the perimeter of the low wall.
"Brother Gu." Lu Weiwei turns her head and looks at Gu Chen.
She saw a grove with a smile
"Well." Well, the higher the ladder is, the better it is
Gu Chen said with a smile: "that's right. If the murderer went over the wall from this place, according to the map, through the grove in front of him, it would be the pond of the park."
"That is to say, the park pond is the first scene of the crime, and there is a high possibility of it?" Li Zhiqiang asked.
Gu Chen responded directly: "at present, in theory, it is, but we still need to collect the flowers by the lake as specimens and give them to instructor Zhang, who will select and compare them, so as to find out the real death site of Wang Jinshan."
"So what are you waiting for?" Police officer Wang can't wait. Scholar Lu Weiwei's run-up action just now jumped easily and directly over the wall.
Then came Gu Chen, he Wenjun, Liu Zhiqiang and more police officers.
We searched all the way along the path. On the road, we also found many new footprints, which were photographed and measured by Gu Chen, and recorded various data on the new footprints.
To Gu Chen's surprise, there are a lot of flowers by the lake, but they are also distributed in small areas, which brings convenience to everyone's job search.
Gu Chen pointed to the right direction and said: "officer he, we three along the right side of the pool to look for, you go to the left side."
"Yes." He Wenjun readily agreed.
Then, we separated at the entrance of the trail, looking for flowers by the lake.
Gu Chen first came to the first place full of flowers;
after searching around carefully, he found that there were two kinds of flowers.
Gu Chen took out the transparent evidence collection bag directly and put two kinds of flowers in two small transparent evidence collection bags.
And pick up the stones on the ground, mark the number of the search site at the lakeside, and then enter the next search site.
It was not until Gu Chen came to the third place full of flowers along the lakeside that Pang found that there was a deep water bank, and the river bank was perpendicular to the water.
Gu Chen frowned and began to focus on the lakeside bank with his professional observation.
But just as he was about to finish the flower growing place along the lake, Gu Chen unexpectedly found that there seemed to be some deep scratches in the soil on the Bank of the river.
Gu Chen quickly squatted down and photographed the scratch with his mobile phone.
Lu Weiwei, who was searching at another place on the Bank of the river, found Gu Chen's small movements, so she quickly approached her and asked, "younger martial brother Gu, have you found anything?"
"Come and see what this is?" Gu Chen also gave up a body position, pointing to the Bank of fat scratch road.
Lu Weiwei frowned and quickly squatted beside Gu Chen. Then she said in amazement: "this Isn't this a sign of finger scratching? "
"Scratch marks?" Smell speech Gu Chen this side has found, officer Wang also hastened to come over.Gu Chen nodded slightly and said seriously: "yes, it's really the scratch of human hands, and have you noticed that this scratch is in the opposite direction, it's from the lake up."
"Let me see." Reminded by Gu Chen, Lu Weiwei quickly stretched out her palm for comparison.
The hesitant mud mark is not particularly obvious, so after comparing, Lu Weiwei really found the merit, and immediately said with surprise:
"yes, it's from the lake to the outside. You see, the outside is a little high, the inside is very deep, this is obviously a mud pit in the dark of several fingers."
"Pulling out of the lake?" Officer Wang frowned slightly. Then he looked at the flowers around him and said, "the lake is full of wild flowers. Is this the place where Wang Jinshan died?"
"It's basically right." Gu Chen plucked several wild flowers next to the mud mark, as if in a small transparent forensics bag, and then on the periphery of the number, specially with a stroke.
"In order to check the integrity, we have to take the lake around to make sure that there is only one scratch around the lake."
"No problem." Although Lu Weiwei knows that, based on this, it can be clearly seen that everyone's previous inference is correct, and Wang Jinshan can be drowned here.
That is to say, when Wang Jinshan was about to drown, he tried his best to grasp everything on the bank and tried to climb up.
That's why there is dirt and pollen powder in Wang Jinshan's fingers.
"But what is it that prevents him from surviving? The murderer? " Lu Weiwei is thoughtful.

That is to say, when Wang Jinshan was about to drown, he tried his best to grasp everything on the bank and tried to climb up.
That's why there is dirt and pollen powder in Wang Jinshan's fingers.
"But what is it that prevents him from surviving? The murderer? " Lu Weiwei is thoughtful.

Gu Chen put on a pair of new gloves again and pushed the tray beside instructor Zhang Hui to one side. Then he asked, "drillmaster Zhang, what do you mean by abnormality?" "Look at this." Zhang Hui gives up a body position and gives the position of microscope to Gu Chen. Gu Chen bows down directly and looks at the microscope for a while. Suddenly, he frowns: "yes Is it pollen? " "Yes, it's pollen, and it's mixed with bits of clay." Zhang Hui said. Lu Weiwei was stunned: "so So, this is not the dirt that Wang Jinshan scratched out at all? " "It's true." Gu Chen took back his eyes and said in surprise: "if Wang Jinshan was swimming in the swimming pool, there would not be so much pollen and soil debris between the nail cracks." After seeing Lu Weiwei and officer Wang, Gu Chen asked again, "elder martial sister Lu, senior brother Wang, do you remember having dinner with Wang Jinshan yesterday?" "What do you want to say?" Lu Weiwei seems to have guessed Gu Chen's meaning. Gu Chen went to Wang Jinshan's body, lifted Wang Jinshan's left hand and asked, "did you find so much dirt on his fingernails yesterday?" "Absolutely not." Lu Weiwei affirmed: "yesterday at dinner, Wang Jinshan's hands are very clean, absolutely will not appear so much dirt." "Indeed." Gu Chen put Wang Jinshan's left hand down gently: "I sat by his side yesterday, and his hands really didn't have so much dirt." "But the problem is, after he and his assistant left yesterday, the assistant can't contact Wang Jinshan today. Until the police call, Wang Jinshan has been floating in the swimming pool." "It is known that Wang Jinshan died in the early hours of yesterday morning, and he died of drowning. Then what happened during the period when he left the hotel and went home is the key to the investigation." "Yes." He Wenjun very much agreed with Gu Chen's opinion, but also actively echoed: "if Wang Jinshan has never gone out since he entered his home, it is impossible that there is so much suspicious dirt in the gap between his fingers." "What's more, we searched Wang Jinshan's house at that time. There were almost no flowers in his house, but some lawns in the yard." On hearing the speech, officer Wang nodded slightly and said, "if so, where does the pollen come from? It can only explain one truth. This swimming pool may not be the first scene of the crime. " "It was Wang Jinshan who was drowned in other places, and he didn't even know it Move to the pool at Wang Jinshan's home to create the illusion of accidental drowning. " After all, it is learning for application Today's training class, just talked about the relevant knowledge, officer Wang can immediately contact. Liu Zhiqiang nodded slightly: "that's right. If there are no flowers at home, how can there be pollen debris in the nail seams? The pool at home is definitely not the first scene. " The scene soon discussed Gu Chen sat back to the test bench again, observed the pollen material through the microscope, and then turned to ask Zhang Hui: "instructor Zhang, it was a short time from Wang Jinshan to his accidental death." "If that's the case, then the flower should be growing nearby. Does your lab have an archive of this kind of data?" "This..." Zhang Hui was stunned and was suddenly asked by Gu Chen. He was embarrassed and said, "there were some pollen data before, but they are not comprehensive." "If you want to talk about water quality data, we have a lot of data in our laboratory." "This is no longer the key." Gu Chen stood up directly and said, "this kind of pollen should be the reproductive organ of gymnosperms and angiosperms. It is very small, and its structure can only be seen through a microscope." "But different plants have different shapes of pollen. According to the shape and size of pollen, symmetry and polarity, the structure of pollen wall and the surface sculpture, it is possible to identify families, genera and species of plants." Looking at Zhang Hui, Gu Chen added: "most plant pollen is easy to collect. It can be preserved for quite a long time without losing vitality. This plant should be nearby. I want to go over to investigate and collect the flowers nearby to see which ones are specific, so as to judge the location of the crime." "But Looking for a needle in a haystack Zhang Huigang wanted to pour cold water on it, but Gu Chen opened the mobile phone map directly. Liang said in front of Zhang Hui: "instructor Zhang, I have already checked. Wang Jinshan's home is backed by a small hillside. There is very little water there. There is only one park pool. I want to go there and have a look. Maybe this is the first scene of the crime." "You seem to have a point." Hearing Gu Chen's analysis, Zhang Hui nodded silently, then looked at he Wenjun and said, "what do you mean?" "I think it works." He Wenjun said. "That's good." Seeing that they had reached a tacit understanding, Zhang Hui took a deep breath and said, "I'll try my best to study this pollen structure to determine which species as soon as possible." "You go to the park pond first, and you may find some new discoveries. If there are flowers by the pond, collect the specimens."After thinking about it, Zhang Hui said again, "remember to number the flowers and places you picked." "Yes." Gu Chen nodded slightly, but suddenly remembered that this was the boundary of the Yangcheng police force. He Wenjun was asked in a tone of inquiry: "officer he, I don't know if there is a chance to partner with your criminal investigation team two." "Of course it can." Gu Chen asked for a battle, and he Wenjun was certainly willing. After all, it is the investigation work. The main task needs more people, so more people will have more strength. What's more, Gu Chen's training class belongs to self-study time in the evening, which does not delay the class, so it is a natural course. After reaching the cooperation intention, Gu Chen quickly went to the storage cabinet in the detection room and found more small evidence bags. Then he said, "it should not be too late. We will start right now." He Wenjun and Liu Zhiqiang, driving with Gu Chen team and many police officers from the second criminal investigation team, rushed to Wang Jinshan's death site. This area is a mature community, the development time is early, the housing structure is relatively old. I heard that the police officer who knew the trade said that this place was a villa bought by Wang Jinshan when he just made a fortune. Of course, later Wang Jinshan also bought more villas, which is also later. However, since leaving Jiangguan fund and taking care of its own portal, Wang Jinshan has been at a disadvantageous start and the fund has been losing money year after year. When Wang Jinshan can't hold on, he will choose to sell a suite to ease the huge financial pressure. If it had not been for the scenery that many people had bought houses in those years, Wang Jinshan today would have fallen. In addition, the housing price of Yangcheng is extremely high, which also gives Wang Jinshan a buffer opportunity. It is said that a listed company invested by Wang Jinshan was difficult to operate and close to the verge of bankruptcy. In order to save the listed company, Wang Jinshan sold a school district house in Yangcheng. Then the company, which was on the verge of bankruptcy, came back from the dead. The profit margin between the purchase and sale of house price exceeded the total profit of the listed company in three years. On that day, the crisis never existed alone. The poor performance of the funds in his hands made Wang Jinshan's capital less and less. With one after another selling houses to save the market, almost hollowed out Wang Jinshan's accumulated wealth in these years. However, because this villa is the first villa that Wang Jinshan earned by working in Jiangguan fund, it is of great significance to Wang Jinshan, so it is well preserved. Wang Jinshan has always liked to live here. After learning about the villa from the police, Gu Chen crossed the cordon and entered the pool where Wang Jinshan drowned. At this moment, the water in the swimming pool seems to be a little muddy. Gu Chen investigates the surrounding monitoring, but finds that there is no monitoring here, so he can't help frowning. "What's the situation? There's no surveillance around this kind of mansion? " Gu Chen asked he Wenjun. He Wenjun also hastily explained: "there used to be, but later when we were investigating here, we also asked Wang Jinshan's assistant." "What he means is that Wang Jinshan doesn't like to set up monitoring in the courtyard, because there are swimming pools in the courtyard. If the monitoring goes wrong, it's easy to expose privacy." "Therefore, only the road in front of Wang Jinshan's home is monitored at the intersection. Other places, for fear of privacy, have been removed by Wang Jinshan." "Withdrawn?" After hearing what he Wenjun said, officer Wang did not dare to set up a channel: "although for a financial magnate like him, who will he meet? It's private to talk to someone about cooperation, or to work with someone at home. " "Moreover, any gossip may affect the trend of his fund, so these people are usually very cautious, and it is not unreasonable to remove the surveillance cameras in the courtyard." "Yes." A police officer with a Cantonese accent also said: "this is true, especially our Cantonese people are used to speculation in stocks and funds." "Every big man and senior management of these listed companies must be strict with themselves. Otherwise, a little bit of frivolous news comes out, which will have a bad impact on the company, and the stock price fund will plummet all the way." "So these big guys, usually pay attention to personal privacy, it is estimated that hackers may invade the monitoring system. This kind of thing has happened before." "So it is?" On hearing this, officer Wang no longer cares about these things. It just feels like a double-edged sword Gu Chen walked along the fence and found two obvious friction marks on a low wall. After that, I found two marks on the floor. Looking at Gu Chen's happy face, he Wenjun stepped forward and asked Gu Chen, "officer Gu, do you have any findings?" "Take a look at this." Gu Chen did not give the answer directly, but gave up a body position, and only showed he Wenjun the four friction marks on the wall and floor tiles.He Wenjun frowned and quickly approached the trace. After repeatedly confirming, he looked at Gu Chen in surprise: "you mean This trace of the ladder "Yes, and it's new." Gu Chen also responded directly. Smell speech two people's speech, one side of Lu Weiwei, Wang police officer and Liu Zhiqiang three people, also hastened to come over. "Is there something new? What ladder? " Lu Weiwei stepped forward to observe Gu Chen. She immediately understood Gu Chen's meaning and said with a smile: "younger martial brother Gu, what do you mean It is very likely that the murderer used a ladder to climb over the wall and transport Wang Jinshan's body to the swimming pool through this site? " Gu Chen didn't speak, just nodded slightly. But standing on the side of Liu Zhiqiang said: "then why not go to the gate?" He Wenjun knocked on Liu Zhiqiang's head and said, "stupid, go through the gate. Isn't it more troublesome to deal with traces?" "On the floor, on the door handle, where there is a trace, do you think it is easy to deal with in a short time?" "Well, that seems to be the case." After Liu Zhiqiang observed the traces near the wall, he suddenly realized: "if you transport the corpse in this place through the ladder, it will save a lot of trouble to clean up the traces." "After all, the courtyard is not as exquisite as the home, leaving a little trace, it is difficult to be noticed." Gu Chen smell speech, also slightly nod: "officer Liu said is very reasonable, the reason why the murderer does not go through the door, is also for unnecessary trouble." "After all, there is a little trace left in the room. In the eyes of the police, it is also infinitely enlarged. The murderer is not so stupid." Listening to Gu Chen's explanation, Lu Weiwei seemed to understand the truth. She stepped back a few steps. Suddenly, she pushed her right leg backward, her forefoot grasped the ground, and quickly rushed toward the wall. With the help of this kick, Lu Weiwei easily climbed over the wall, which found that there was a small forest near the perimeter of the low wall. "Brother Gu." Lu Weiwei turns her head and looks at Gu Chen. She saw a grove with a smile "Well." Well, the higher the ladder is, the better it is Gu Chen said with a smile: "that's right. If the murderer went over the wall from this place, according to the map, through the grove in front of him, it would be the pond of the park." "That is to say, the park pond is the first scene of the crime, and there is a high possibility of it?" Li Zhiqiang asked. Gu Chen responded directly: "at present, in theory, it is, but we still need to collect the flowers by the lake as specimens and give them to instructor Zhang, who will select and compare them, so as to find out the real death site of Wang Jinshan." "So what are you waiting for?" Police officer Wang can't wait. Scholar Lu Weiwei's run-up action just now jumped easily and directly over the wall. Then came Gu Chen, he Wenjun, Liu Zhiqiang and more police officers. We searched all the way along the path. On the road, we also found many new footprints, which were photographed and measured by Gu Chen, and recorded various data on the new footprints. To Gu Chen's surprise, there are a lot of flowers by the lake, but they are also distributed in small areas, which brings convenience to everyone's job search. Gu Chen pointed to the right direction and said: "officer he, we three along the right side of the pool to look for, you go to the left side." "Yes." He Wenjun readily agreed. Then, we separated at the entrance of the trail, looking for flowers by the lake. Gu Chen first came to the first place full of flowers; after searching around carefully, he found that there were two kinds of flowers. Gu Chen took out the transparent evidence collection bag directly and put two kinds of flowers in two small transparent evidence collection bags. And pick up the stones on the ground, mark the number of the search site at the lakeside, and then enter the next search site. It was not until Gu Chen came to the third place full of flowers along the lakeside that Pang found that there was a deep water bank, and the river bank was perpendicular to the water. Gu Chen frowned and began to focus on the lakeside bank with his professional observation. But just as he was about to finish the flower growing place along the lake, Gu Chen unexpectedly found that there seemed to be some deep scratches in the soil on the Bank of the river. Gu Chen quickly squatted down and photographed the scratch with his mobile phone. Lu Weiwei, who was searching at another place on the Bank of the river, found Gu Chen's small movements, so she quickly approached her and asked, "younger martial brother Gu, have you found anything?" "Come and see what this is?" Gu Chen also gave up a body position, pointing to the Bank of fat scratch road. Lu Weiwei frowned and quickly squatted beside Gu Chen. Then she said in amazement: "this Isn't this a sign of finger scratching? " "Scratch marks?" Smell speech Gu Chen this side has found, officer Wang also hastened to come over.Gu Chen nodded slightly and said seriously: "yes, it's really the scratch of human hands, and have you noticed that this scratch is in the opposite direction, it's from the lake up." "Let me see." Reminded by Gu Chen, Lu Weiwei quickly stretched out her palm for comparison. The hesitant mud mark is not particularly obvious, so after comparing, Lu Weiwei really found the merit, and immediately said with surprise: "yes, it's from the lake to the outside. You see, the outside is a little high, the inside is very deep, this is obviously a mud pit in the dark of several fingers." "Pulling out of the lake?" Officer Wang frowned slightly. Then he looked at the flowers around him and said, "the lake is full of wild flowers. Is this the place where Wang Jinshan died?" "It's basically right." Gu Chen plucked several wild flowers next to the mud mark, as if in a small transparent forensics bag, and then on the periphery of the number, specially with a stroke. "In order to check the integrity, we have to take the lake around to make sure that there is only one scratch around the lake." "No problem." Although Lu Weiwei knows that, based on this, it can be clearly seen that everyone's previous inference is correct, and Wang Jinshan can be drowned here. That is to say, when Wang Jinshan was about to drown, he tried his best to grasp everything on the bank and tried to climb up. That's why there is dirt and pollen powder in Wang Jinshan's fingers. "But what is it that prevents him from surviving? The murderer? " Lu Weiwei is thoughtful. www.mylovenovel.com , the fastest update of the webnovel!
