Chapter 41 You are definitely a criminal (seeking support, first update)

"Hahahaha, Chen Fan, stop hiding it. Tell me, let's go in."

"Tell me, don't hide it, you know something."

"You can even open a bank, and you still say you are not a criminal?"

"Tell the truth and try to get leniency, really."

Chen Fan was speechless and said,"I really am not."

Old Li said,"If I didn't know about your past, I would even suspect that you were planning to do something bad. I was curious. Why are you studying these things when you are a good young man?"

"Please tell me what I am studying."

"Cut people, open a girl's clothes in three seconds, open the lock, tell me, which of these is normal"

"It's just a personal hobby, is that not okay?"

Go aside.

Old Li was too lazy to get involved.

Several people entered the vault, and there was money taken away from the vault.

Old Li said:"When these dead people died, someone threw the money in the car, and then fell down. After they fell down, the driver also left. We checked the surveillance, but it was useless." Is it useless to check the surveillance?

Chen Fan said:"There is a stupid way."

Stupid way?

Li Tian said:"Stupid way?"

Old Song said:"Don't think about it. I took everyone to run around and tried everything I could think of." Chen Fan shook his head and said:"It's a very stupid way. Isn't this a live broadcast? I'm embarrassed to say it. I'm afraid that if I say it, the other party will easily know it."

"It doesn't matter. Tell him, it's better for him to know, so that we can catch him."

Xiang Qinqin said:"I think I know what a stupid way is."

"Fingerprint identification, the simplest fingerprint identification, is to build a database, then bring in fingerprints for comparison. After the comparison, the person who does not appear often is the murderer."

Li Tian laughed and said,"That's really not elegant enough."

"Well, you can reason, so you can infer it."

Li Tian was speechless. Old Song had already investigated almost everything he could think of.

Several people looked at each other and finally decided to conduct a big data search.

However, the premise is that this case can be defined as a homicide, otherwise, it really can't be solved.

The big data method is actually very simple. In an area, there are actually only so many active people. The murderer must come to investigate the scene. The person who doesn't appear often is the murderer needed.

And how to find people who don't appear often in the crowd is very puzzling.

This requires the work of observation.

Video comparison, fingerprint comparison, street search and so on.

This method is laborious, but what if it is not a homicide? Just a coincidence?"

This statement, in fact, no one present believed it was a coincidence.

Soon, in the laboratory, Old Liu gave a data

"It is a poison that will accelerate the activity of the human heart, but there is no way to compare it. We don't know what it is yet. It is not in the category of drug detection. It is temporarily defined as unknown. It can be classified as a homicide."

Then a group of people began to act. There are a lot of video recordings, plus various visits, and basically the entire forensic department is in operation.

Chen Fan is a guest here and does not need to participate, but the boring task of comparing fingerprints is really a blow to the program.

Popularity will decline, this is inevitable. Forensic doctors cannot sit down. Every thing is so explosive and exciting.

When a problem arises, the most primitive and stupid way is often the best.

Li Tian provided help. That is, the profile of the identity

"The nameless poison, researched by himself, so this person is first of all a loner"

"Most of them are young and aloof, not too old, tentatively estimated to be between 20 and 30.|"

"If the social recognition is very low, then the appearance must be not high, look for ugly people"

"In addition, people who are good at mechanics but don't earn much are unsuccessful and have average clothing brands."

"People who work in hospitals or have contact with hospitals"

"Well, this person should be weak and thin."

"Besides, if you can drive, the car should not be expensive."

"Old Song, go to any place on the market where you can investigate any material, and then think about it, and find someone according to my profile."

Li Tian is indeed known as a reasoning expert. After all, the direction of the basic person has been narrowed down a lot.

At night, the database was established and basically took shape.

Old Zhou here was exhausted and fell down, a little confused, and said:"I really can't stand it. To be honest, this kind of thing should not happen again."

Old Liu said:"He is already at the doorstep, can we let this brat go?"

Bai Lu said:"Why did this person do this?"

Zhang Yishan said:"When I was in the police station, a policeman said that some people go to extremes, and in fact it may be a very small case."

"Or maybe it was a matter of grievance that made this person go to extremes. This matter may be so small that we cannot care about it, or it may be so big that we cannot handle it."

Suddenly, Li Tian reacted directly and said,"I know, why am I so stupid."

Everyone was puzzled.

"This person must be someone who knew one of the five people who died. The reason why these people were able to come into contact must have been because of this person's introduction."

"Well, you just need to start from your side."

""We have checked before, haven't we?"

Bai Lu asked.

Li Tian said,"The check is just about life and contact. I want to ask other questions."

On this side, Lao Song learned that the other side had received an order and called again. Soon, he locked on a person.

Age, height, appearance, income, all met the requirements.

"Let's arrest him, he didn't run away, it's this guy."

Here, several people are ready to lead the team.

To be precise, when they said to arrest him, he was actually at the door of that person's house.,

Variety show live broadcast, it is impossible to really tell everything, what if the person runs away?

Li Tian continued:"By the way, this person is a woman."

????

In an instant, the whole room, the live broadcast room, was quiet, only the breathing sound was back. ps: Please support, thank you all.
