Detective: I can see the criminal record

Chen Nan doesn't look like a very successful meteorite dealer.

This was Cen Lian's first reaction when he entered the community where Chen Nan's family lived.

Although the community is in a good location, the buildings are a bit old and the management inside the community is a bit chaotic. It is not a high-end community at first glance.

More importantly, the property management of this community can be seen at a glance that it is not very caring, and the greening is a mess.

"Is it so unprofitable to do meteorite business?" Tang Hua asked Cen Lian curiously when parking the car.

Cen Lian shook his head helplessly, "I am just an enthusiast. How do I know whether those collectors make money? You are talking as if I have money to collect."

Tang Hua thought about their monthly salary and felt that Cen Lian was right.

Wu Qiushan took out the survey box from the trunk and looked up at the high-rise where Chen Nan's family lived.

"I live on the twelfth floor. I don't know if the surveillance inside and outside the elevator has captured anything." He muttered and looked at Cen Lian.

"I brought my computer. Let's investigate separately." Cen Lian came with a notebook on his back. He had expected that he would start watching the surveillance soon. After all, he couldn't help Wu Qiushan much in the field of trace detection.

The group took the elevator to the 12th floor. Xiao Gao opened the door with a key. Cen Lian looked around and didn't see any family with surveillance installed at the door.

This is an ordinary elevator building with two elevators and four households. If the family opposite Chen Nan's house installed surveillance, there might be more clues.

However, there should be only a few people in this community who would install surveillance.

Wu Qiushan changed into shoe covers, dressed neatly, and entered Chen Nan's house first.

A round of sampling had been carried out here before, so there was no need to build a plank bridge to enter again. Cen Lian also put on shoe covers and followed in.

"Is this room like this when you came before?" Wu Qiushan asked Xiao Gao before opening the tool box.

"Yes, our trace investigators came and took simple samples and kept the scene as it was." Gao Haolin said with some trepidation, and finally breathed a sigh of relief when he saw Wu Qiushan silently opening the tool box for on-site investigation.

It seems that these colleagues from Yunling Province are relatively easy to talk to.

While Cen Lian was checking the traces in Wu Qiushan's room, he put on shoe covers and gloves and began to check all the photos in Chen Nan's house.

As a collector who can be called a collector and a middleman, Chen Nan, like most collectors, is very happy to participate in various gatherings in his circle. Of course, this kind of gathering is generally called a "seminar" in a nice way.

Seminars always require group photos, and Cen Lian's purpose this time is to find these group photos.

Since the two deceased, Zhu Yao and Qin Xingguo, are both in this circle, he is more inclined to believe that this case must be related to meteorite collection.

Tang Hua followed Wu Qiushan and helped take photos. He had a clear understanding of his miscellaneous nature, so Gao Haolin and his colleague Zhang He had no room to play.

Forensic doctor Lin stood in the room and looked casually. She was a professional forensic doctor and graduated from a medical university instead of a police school, so she could not provide much help in the on-site investigation.

Cen Lian quickly found a large group photo in Chen Nan's study.

The location of the group photo looked like it was in the lobby of a hotel. There was a big red banner behind it, which read: "Congratulations to the 37th National Meteorite Collectors Seminar for its complete success."

This seminar was held this year, about three months ago. At that time, someone in Cen Lian's circle of friends also posted this group photo.

But at that time, he didn't have such a thing as a plug-in, and he couldn't see the text bubble popping up on this photo.

[Name: Yang Guangming]

[Gender: Male]

[Age: 54 years old]

[Criminal record: Prostitution in Jiangyuan City 175 days ago]

[Prison record: None]

Yang Guangming is a man near the edge of the first row in the photo. Cen Lian has no impression of this man. His crime is not a big deal. If he goes to see him in a few days, he may disappear. After all, the prosecution period for this thing is only half a year. I just don’t know if his wife, who is probably over 50 years old, will be infected with any disease.

The text bubble below is a bit interesting.

[Name: Tian Xianzhong]

[Gender: Male]

[Age: 48 years old]

[Criminal record: Robbed and killed Qin Xingguo in Jiangyuan City 19 days ago]

[Prison record: None]

Tian Xianzhong is also a little famous in the meteorite collection circle. Cen Lian has also seen several popular science videos he shot and produced.

In his impression, this man always acts like an old scholar. Although he is still young, he has already played the three-piece set of middle-aged people such as drinking tea, skewers and fishing.

I don't know what conflict he had with Qin Xingguo, and what he snatched from Qin Xingguo.

"This person is not right," Cen Lian said slowly while holding the photo, "Check the relationship between Chen Nan and Tian Xianzhong."

Gao Haolin and Zhang He didn't know what happened, and they watched the remaining people in the room move except Wu Qiushan.

"Let me see." Forensic Doctor Lin took the photo and compared it with Cen Lian's police communication. "I'll check Tian Xianzhong, Tang Hua, you continue to help Wu Qiushan. If there is a problem with this Tian Xianzhong, then Chen Nan's family may have his DNA."

Lin Xiangqi said and went out.

Cen Lian was thinking about one thing. Judging from everything that happened now, he thought that the meteorite must be the one that caused these people to fight, and it was probably the meteorite that was finally placed next to Chen Nan's body.

I just don't know if fingerprints can be extracted from the meteorite.

"Brother Yue, let me ask you something," he interrupted Wu Qiushan who was working, "Can fingerprints be extracted from meteorites?"

Although he himself has a certain level of criminal investigation technology, it is better to consult professionals for such detailed questions.

Wu Qiushan didn't even raise his head, "It depends on the situation. Fingerprints can be extracted by normal grasping, but because of the density of meteorites, I estimate that the integrity is very poor."

Cen Lian nodded, it seems that the technicians at the district bureau can give it a try.

Tang Hua understood and went out to make a phone call.

The two young men from Jiangyuan City Bureau looked at each other. They really couldn't figure out what had just happened. Why did Cen Lian simply look at the photos for a while, and this case suddenly had an investigative direction?

Tang Hua patted Gao Haolin on the shoulder before leaving.

"Young man, you will understand after staying with us for a long time."

Gao Haolin was even more confused.

Cen Lian didn't have time to care about what they were thinking, because he had already turned on the surveillance video.

Now that they had a clear goal, the next step was to see if Tian Xianzhong had been to Chen Nan's house.

Although he had nothing to do with Zhu Yao's death, and Chen Nan had nothing to do with Qin Xingguo's death, Qin Xingguo's blood DNA was left in Chen Nan's trunk, which meant that there must be a connection between the two of them, at least Tian Xianzhong must have used Chen Nan's car to dump the body.

So, Chen Nan's house became strangely quiet.

Cen Lian took off his shoe covers and gloves and sat outside the door to watch the surveillance video. Wu Qiushan was very quiet in the house to extract various biological traces in detail. Gao Haolin and Zhang He looked at each other and finally found their own space to play, so one followed Wu Qiushan to help, and the other helped Cen Lian get the computer to connect to the hard drive.

Many of the surveillance cameras near Chen Nan's home are broken, but this cannot be said to be intentional. Based on Cen Lian's five years of community work experience and his understanding of this kind of community, if one-third of the surveillance cameras in the entire community are in normal use, it can be considered that the property management is fulfilling its duties.

After all, the property management fees of this kind of community are not enough to support their frequent replacement of cameras. Basically, they will only symbolically replace a batch of new ones after a large number of electric vehicles are lost and the owners complain once.

After that, these new cameras are gradually damaged, and then a large number of electric vehicles are lost again.

This is actually the norm in most communities. As for those who replace every camera when there is a problem, the housing price and property management fees are at least doubled than here.
