Before long, Zhao Ming and the technical team arrived at the scene.
"Team Zeng, sorry to be late." Zhao Ming scratched his head.
"What are you doing? It's been a long time. "
"I went to play CS with my friends. It's a little far away from the city."
"Yes, life is quite colorful." Zeng Ping said with a smile.
"I want to practice my experience in gunfight, so that I can use it to catch criminals in the future." Zhao Mingdao.
Zeng Ping also did not hold on to this stubble. He found Lu Wen of the technical team and asked him to go to the toilet to collect the fingerprints of the camera.
"Do you have anything from your boyfriend?"
"There's his water cup under the table." With that, Chen Luyan would reach for it.
"Don't move. Let me do it." Wearing gloves, Han Bin took out the water cup from under the table.
"There are fingerprints." Han Bin gives the water cup to the rest of the technical team to collect fingerprints.
"Team Zeng, are there fingerprints on the envelope and USB flash drive?"
"No obvious fingerprints."
After a while, Lu Wen and another colleague of the technical team collected their fingerprints and used the portable police fingerprint comparison machine to conduct fingerprint comparison on the spot.
In this way, the direction of investigation can be determined as soon as possible and the time of solving the case can be shortened.
"Team Zeng, the fingerprint on the camera and the fingerprint on the cup are not the same person."
Zeng Ping answered and handed the envelope and USB flash disk to Lu Wen. Some invisible fingerprints could not be seen by the naked eye, but they did not mean there was no fingerprints. They could be detected by chemicals and instruments.
Of course, if you wear gloves, or if you've been wiped, you don't leave fingerprints.
"Comrade police, can my boyfriend get rid of the suspicion?" Chen Luyan breathed a sigh of relief.
If it was really his boyfriend who did it, she would feel even more terrible.
Zeng Ping did not answer, although the fingerprints do not match, but can not rule out the suspect accomplice, his boyfriend has the key to the home, is still suspected.
"Team Zeng."
At this time, Li Hui, who was checking the monitoring, came back.
"Did you find anything?"
"I went to the monitoring room and asked, the front door, the first floor hall and the elevator are monitored, but the stairs, the back door and the corridor of the apartment building are not monitored." Li huidao.
"That is to say, as long as the suspect knows the situation of the apartment or steps on the spot in advance, he can completely avoid monitoring." Tian Li analysis.
"Apartment buildings are different from residential buildings. Generally, there are only one or two, and the security is worse." Han Bin said.
"From the existing monitoring, is there anyone who can be found?" Zeng Ping Road.
"No
"I think we should let Miss Chen see if there are any people she is familiar with." Han Bin suggested.
Zeng Ping nodded: "in this case, acquaintances are more likely to commit crimes."
"I copied all the videos." Li Hui took out a USB flash drive.
Later, Chen Luyan uses a computer to watch the monitoring.
Han Bin and others discussed the case in a low voice in a slightly distant position.
"Team Zeng, the loophole of monitoring is too big. Suspects with a little brain will climb the stairs, so it is unlikely to check the monitoring." Li Hui discussed.
"I think, but her boyfriend is still suspected. There is no sign that the door lock has been prized. There is no key to enter the door. There is no way to install the camera." Tian Li Road.
"Can't fingerprints be compared?" Zhao Mingdao.
"Before the installation of that camera, others may have touched it, or even the fingerprints of the person who sold it." Tian Li explained.
"In that case, the case is complicated." Li huidao.
"Han Bin, tell me what you think."
"I've just seen that camera, and I think we can take it as the direction of investigation."
"How to find out?"
"Since the camera has been put, we must watch it. The video in the camera is either copied or uploaded through the Internet, so that it can reach the suspect." Han Bin said.
"That's a good entry point." Zeng Ping nodded and analyzed: "if it's a copy, you need to replace the USB flash disk frequently, and the suspect may have been to the victim's home more than once; if it's a network upload, the camera must be connected to the wireless network."
"I have just seen that the camera should be a video uploaded through the network. The suspect can monitor it with his mobile phone or computer." Han Bin said.
"The camera is so secret, there are walls all around, and the network signal is too far away to come, that is to say, the suspect is using the surrounding network." Li huidao.
Han Bin took out his mobile phone. He just took a few pictures of the camera and observed them carefully: "342"
"what do you mean?"
"The network account used by the camera."
"You mean 342?" Chen Luyan on one side chimes in.
"Do you know whose wireless network is near here?"Chen Luyan opened her mouth and said, "this is my home. The network I linked to is 342."
"Who knows your network password?" Li Hui asked.
"Just me and my boyfriend."
"Network is also your boyfriend, help to install it?"
"This is not. When I came, the landlord had already installed it." When Chen Luyan said this, she seemed to think of something: "by the way, the password is set by the landlord, and he knows it."
"So, besides Miss Chen's boyfriend, the landlord is also suspected." Zeng Ping Road.
"But the landlord doesn't have a key either." Tian Li Road.
"It's a bit preconceived. The landlord doesn't have a key now, but he did. Before Miss Chen moved in, she might have installed a camera." Han Bin said.
"Yes." Tian Li suddenly realized: "that should use the fingerprint collected on the camera to compare with the landlord's fingerprint."
Zeng Ping went over and checked: "Miss Chen, have you wiped the router?"
"The router is on the desk. As soon as I open the window, it gets dusty. I often clean it."
"Routers are generally installed by people from network companies, and the fingerprints collected may not be my own." Han Bin said.
"Think about it. Do you have anything from the landlord at home, or have you left his fingerprints?" Tian Li Road.
Chen Luyan frowned and thought for a moment, then shook her head: "the house has been rented for two months. After renting it, I have cleaned it up. I can't remember it for a while."
"When you signed the house lease contract, did you press your fingerprints?" Han Bin said.
"I remember that when I signed the contract, I didn't want to press it. The landlord suggested that both parties press their fingerprints. He said it was more secure and reassuring."
"Take the contract."
A moment later, Chen Luyan brought the lease contract. Her fingerprints were stained with ink. She didn't need to collect them. She just compared them directly.
After some comparison, Lu Wen confirmed: "the fingerprints on the lease contract are completely consistent with half of the fingerprints collected on the camera. This person is highly suspicious."
Because on the camera, only half of the fingerprint was collected, and Lu Wen could not be 100% sure that it was the same person's fingerprint.
However, this is enough for Zeng Ping and Han Bin.
In a case, the possibility of two people having the same half fingerprint is almost negligible.
Please report us if you find any errors so we can fix it asap!
