Detective from the Future

It didn’t take long for Zhao Ming and the technical team to arrive at the scene.

“Chief Zeng sorry, it’s late.” Zhao Ming scratched his head.

“Why did your kid go? It took so long to come over.”

“Going to play True Master CS with friends, a little far away,” Zhao Ming said.

“Okay, life is quite colorful,” Zeng Ping laughed.

“I want to practise the gunfight experience, and later I will need to arrest the prisoners,” Zhao Ming said.

Zeng Ping didn’t hesitate to find this, and found Lu Wen of the technical team and asked him to go to the toilet to collect the fingerprint of the camera.

“Are there any items for your boyfriend in your family?” Han Bin said.

“There is his water cup under the table.” Then, Chen Luyan was about to reach for it.

“Don’t move, let me do it.” Han Bin, wearing gloves, took the cup from under the table.

“I have a fingerprint.” Han Bin handed the cup to the other members of the technical team to collect the fingerprint.

“Chief Zeng, are there fingerprints on envelopes and USB drives?”

“No obvious fingerprints,” Zeng Ping said.

After a while, Lu Wen and another colleague of the technical team collected fingerprints and used a portable police fingerprint comparison machine to conduct fingerprint comparison on the spot.

In this way, the investigation direction can be determined as soon as possible, and the case resolution time can be shortened.

“Chief Zeng, the fingerprint on the camera and the fingerprint on the cup are not the same person,” Lu Wen said.

Zeng Ping complied, handed the envelope and USB flash drive to Lu Wen. Some inconspicuous fingerprints could not be seen with naked eye, but it did not mean that they could not be detected by chemicals and instruments.

Of course, if you wear gloves or have been wiped, you will not leave fingerprints.

“Comrade Police, can my boyfriend rule out the suspicion?” Chen Luyan was sighed in relief.

If it was really his boyfriend who did it, she would feel more terrifying.

Zeng Ping did not answer. Although his fingerprints did not match, he could not rule out the suspicion of his associates committing the crime. His boyfriend had the keys to the house and was still suspected.

“Chief Zeng.” Just then, Li Hui, who was watching the monitor, returned.

“Did you find it?”

“I went to the monitoring room and asked that the front door, first floor lobby and elevator are monitored, but the stairs, back door and corridor of the apartment building are not monitored,” Li Hui said.

“That is to say, as long as the suspect understands the condition of the apartment or stepped on it in advance, he can completely avoid surveillance.” Tian Li said.

“Apartment buildings are different from residential buildings. Generally there are only one or two buildings, and security is worse.” Han Bin said.

“Did you find anyone available from the existing surveillance?” Zeng Ping said.

“No.”

“I think it’s time to show Chen Young Lady to monitor if there are anyone she is familiar with,” Han Bin said.

Zeng Ping nodded “In this case, acquaintances are more likely to commit crimes.”

“I copied the video,” Li Hui said.

Later, Chen Luyan used her computer to watch the monitor.

Han Bin and the others distantly discussed the case.

“Chief Zeng, the loopholes in monitoring are too large. Suspects with a little brain will climb stairs to check the possibility of monitoring,” Li Hui said.

“I think, but her boyfriend is still suspicious, the door lock has not been traced, and the camera cannot be installed without the key.” Tian Li said.

“Isn’t the fingerprint inconsistent?” Zhao Ming said.

“Before the camera was installed, it may have been touched by others, or even the fingerprint of the person who sold the camera,” Tian Li said.

“If this is the case, the case will be complicated,” Li Hui said.

“Han Bin, tell me what you think.”

“I looked at that camera just now, and I think it can be used as a troubleshooting direction,” Han Bin said.

“What a troubleshooting method?” Li Hui said.

“Since the camera is placed,

It must be watched. The video in the camera must be copied or uploaded through the network so that the suspect can get it. “Han Bin said.

“This entry point is good.” Zeng Ping analyzed:

“If it is a copy and the U disk needs to be changed frequently, the suspect may have come to the victim’s home more than once; if it was uploaded online, the camera must be connected to a wireless network.

“I just saw that the camera should be a video uploaded through the network, and the suspect can use a mobile phone or computer to monitor it,” Han Bin said.

“That camera is so hidden, there are walls all around, and the network signal that is too far away can’t be reached at all, which means that the suspect is using the surrounding network.” Li Hui said.

Han Bin took out his mobile phone. He just took a few photos of the camera and took a closer look. He said, “342”

“What do you mean?”

“The web account used by the camera,” Han Bin said.

“Do you mean 342?” Chen Luyan interrupted.

“Do you know, which wireless network is nearby?”

“This is my home. The network I link to is 342.” Chen Luyan said.

“Who knows your network password?” Li Hui asked.

“Just me and my boyfriend.” Chen Luyan said.

“The network is also your boyfriend, did you help install it?” Han Bin said.

“This is not, when I came, the landlord had already installed it.” Chen Luyan said this, as if thinking of something: “Yes, the password is also set by the landlord, he also knows.”

“It seems that in addition to Chen Young Lady’s boyfriend, the landlord is also suspicious.” Zeng Ping said.

“But the landlord doesn’t have the keys either,” Tian Li said. UU Reading Books www.uukanshu.com

“This is a bit preconceived. The landlord doesn’t have a key right now, but he used to have it. Before Chen Young Lady moved in, he might have installed a camera,” Han Bin said.

“Yeah,” Tian Li suddenly realized: “The fingerprint collected on the camera should be used to compare with the landlord’s fingerprint.”

“Chen Young Lady, have you wiped the router?” Zeng Ping said.

“The router is on the desk, and the window gets dusty as soon as I open it. I often wipe it.” Chen Luyan said.

“The router is usually installed by a person from a network company. The fingerprint collected may not be my own,” said Han Bin.

“Think about whether you have something from the landlord at home or have left his fingerprints,” Tian Li said.

Chen Luyan frowned for a moment, then shook her head and said, “The house has been rented for 2 months. After renting it, I have been cleaned out, and I also want to do not raise.”

“When you signed the house lease contract, did you keep your fingerprints?” Han Bin said.

“I remember it. When I signed the contract, I didn’t want to press it. The landlord proposed to let the two parties press the fingerprints. He said it was more secure and reliable.”

“Get the contract.”

After a while, Chen Luyan took the lease contract, and her fingerprints were stained with ink pads, so she didn’t need to collect them.

After some comparison, Lu Wen confirmed: “The fingerprints on the lease contract completely match up with the half-fingerprint collected on the camera. This person has a lot of suspicions.”

Because only half of the fingerprint was collected on the camera, Lu Wen was not 100% sure that it was the fingerprint of the same person.

However, this is enough for Zeng Ping and Han Bin.

In one case, the possibility of two people’s half-fingerprints being the same was almost negligible.
