Chapter 41

"Hahahaha, Chen Fan, stop hiding, speak, go in."

"Confess, don't hide it. You know a thing or two."

"You can even open a bank, and you still say you aren't a criminal?"

"Confess honestly, strive for lenient treatment, really."

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

Here, Old Li said, "If I didn't know about your previous affairs, I would even suspect what bad things you, this kid, are planning. I'm just curious, you're a perfectly good young idol, why are you researching these things?"

"What did I research? You make it clear."

"Cutting people, opening a girl's clothes in three seconds, picking locks, tell me, which of these is normal?"

"Just a personal hobby, isn't that allowed?"

Go away.

Old Li was too lazy to get involved.

Several people entered the vault. There was money taken away by someone inside the vault.

Old Li said, "At that time, when these victims died, someone threw money into the car, and then they collapsed. After they collapsed, the driver also left. We checked the surveillance, but it was useless."

Checking surveillance was useless?

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

A stupid way?

Li Tian said, "A stupid way?"

Old Song said, "Don't think about it, I led everyone to run around, everything I could think of, I tried."

Chen Fan shook his head and said, "It's a very, very stupid way. This is a livestream, I'm embarrassed to say it, I'm afraid if I say it, the other party will easily know."

"It doesn't matter, say it. It's best if he knows, that way, it's easier for us to catch him."

Xiang Qinqin said, "I think I know what the stupid way is."

"Fingerprint identification method, the simplest fingerprint identification, build a database, then bring the fingerprints in for comparison. After the comparison is finished, the person who doesn't appear often is the murderer."

Li Tian chuckled and said, "That really isn't elegant enough."

"Then you know how to reason, you deduce it."

Li Tian had nothing to say. Basically, everything that could be thought of, Old Song had already investigated almost completely.

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

However, the premise is that this case can be defined as a murder case; otherwise, it really can't be done.

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

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

This requires a lot of work.

Video comparison, fingerprint comparison, street interviews, etc.

This method is laborious, but what if it's not a murder case? Just a coincidence?"

This statement, actually, everyone present didn't believe it was a coincidence.

Soon, in the laboratory, Old Liu gave some data.

"It's poison, it will accelerate the heart's activity, but it can't be compared. Temporarily don't know what it is, it's not in the poison test category, temporarily defined as 'unknown', it can be defined as a murder case."

Subsequently, a group of people started taking action.

A bunch of video recordings, plus various interviews, basically the entire forensic department was put into operation.

Chen Fan is a guest here and doesn't need to participate, but boring things like comparing fingerprints are really a blow to the show.

Popularity will decline, this is inevitable. Forensic science cannot achieve every single thing being so explosive and exciting.

When a difficult problem arises, the most primitive, most stupid method is often the best.

However, Li Tian provided help.

That is, identity profiling.

"Unknown poison, researching it yourself, then this person is first of all arrogant."

"Arrogant, mostly young people, not old, temporarily set between twenty and thirty."

"Social recognition is very low, then the appearance must not be high, look for ugly ones."

"In addition, knows mechanics, income will not be very high, this kind of person belongs to the frustrated, clothing brands are average, look for these."

"Working in a hospital, or people who come into contact with hospitals."

"Hmm, this person should be physically weak, relatively thin."

"In addition, knows how to drive, the car shouldn't be expensive."

"Old Song, calculate any place on the market where materials can be investigated, and look for people according to my profile."

Li Tian is indeed known as a reasoner. After this set of actions, the direction of the person was narrowed down a lot.

In the evening, the database was built and basically took shape.

Old Zhou here was exhausted and fell down, a bit confused, and said, "Really can't take it anymore. To be honest, this kind of thing, better to have less of it."

Old Liu said, "It's already at the doorstep, can we still let this brat go?"

Bai Lu said, "Why does this person want to do this?"

Zhang Yishan said, "When I was at the police station, some police said that some people go to extremes, actually it might just be a very small case."

"Or, a grievance that made this person go to the extreme. This matter might be so small that we can't even care about it, or it might be very big, so big that we can't handle it."

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

Everyone was puzzled.

"This person must be someone one of the five deceased people knew. The reason these people could come into contact is also definitely because this person introduced them."

"That, just need to start from the people around them."

"Didn't we screen them before?"

Bai Lu asked.

Li Tian said, "Screening was just life, contact, etc. What I want to ask is other questions."

Here, Old Song learned that he received an order, called again, and soon locked onto a person.

Age, height, appearance, etc., income, all were matched.

"Catch the person, no running away, it's this kid."

Here, several people prepared to lead the team.

To be precise, when they said catch the person, they were actually already at the door of that person's house.

Variety show livestream, it's impossible to say 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 livestream room, were quiet, only the sound of breathing echoed.

P.S.: Please support, thank you everyone.
