Police Detective

This method was used by Director Ma of the Ma detachment back then, but it has not been seen for ten years now.

When Team Zhao first started working, he had the honor to work with Director Ma. During that time, Ma Donglai was already a well-known young leader, nicknamed "Captain Team", who meant arresting people everywhere every day.

The prerequisite for arresting people everywhere is that you can find the bad guys.

It’s not that others can’t learn this method of organizing materials, but it’s just that it’s too troublesome. Each case requires a lot of records, and some things have to be kept in mind. Not everyone can master it.

Captain Zhao looked at the familiar format, looked up at Bai Song, thought for a while, and nodded lightly: "Okay, I'll leave these two cases with you."

Captain Zhao's words made several old policemen present a little stunned. These volumes were picked up by Captain Zhao and put into the archives by Captain Zhao. Bai Song took them out and said, "I think they are similar cases." , and then, Captain Zhao recognized it like this?

It's so evil

Involuntarily, the old criminals looked at Bai Song a little strangely. It's not that I admire them, these people have all met Bai Song. What everyone is thinking now is, what does Bai Song have to do with Director Ma? So much so that Captain Zhao is giving face like this?

These veteran criminal police officers knew the situation of the detachment very well. When they encountered Captain Zhao's situation, they began to think wildly.

Bai Song didn't know there was such a misunderstanding, so he directly put the four burglary cases together and prepared for a joint investigation.

Captain Zhao felt a little sad for some reason. He briefly talked about the case, assigned some work to everyone, and left the office.

The robbery case on Sun Dong's side is still a top priority. The bad nature is there. Several people are still investigating things there. There are really not many manpower left for Bai Song.

This was not the time to be polite. Bai Song looked at Sun Dong's staffing and called two young police officers to start handling the case.

These two young policemen were also transferred from the police station. One was named Zhou Run and the other was Liu Hua. They were older than Bai Song and were in the same class as Feng Bao. Bai Song had never seen these two before.

It doesn't matter if you don't know him, everyone knows Feng Bao, we chatted for a few words, and we quickly became familiar with him. From Team Zhao, Zhou Run and Liu Hua also knew that Bai Song had been to Team 3 last year and had served as deputy detective to solve cases, so there was nothing they could not understand about this arrangement. After all, they were new here. I am already very happy to be a detective, there is no need to force this matter.

Bai Song analyzed that these four cases were done by one person. What is the benefit of this? This can be said to have greatly reduced the difficulty of investigation. Each case has some evidence, but it is not enough. What about all the evidence?

In a case last year, there was video data, and the suspect's body shape was captured through the camera, but the following few did not.

Taken together, for the two new cases, surrounding surveillance should be extensively mobilized to obtain sufficient personnel information.

Many people watch sci-fi movies, in which people's anti-counterfeiting and authentication information is based on fingerprints, footprints, faces, irises, and gait.

Things like gait and criminal psychology are not things that ordinary people can study. Gait can be distinguished by two methods. One is by intelligent AI, which is like a sci-fi movie and fully automatic analysis. If nothing else, the third team definitely does not have this technology. The other is to rely on people to identify, which requires investigators to have good cognition.

The three of them stared at each other, would you? Ah, I thought you would? What, shouldn’t the detective come in person to do this?

Obtaining enough peripheral evidence is the job of technicians like Wang Liang, and how to obtain case-solving information from the evidence is a required course for investigators like Bai Song.

Zhou Run and Liu Hua didn't want to worry about this, so they talked to Bai Song, and then they went to adjust the surveillance with the relevant procedures. This work was worry-free and not tiring. Thinking about so many things every day, my hairline is worrying.

Thinking of this, Zhou Run couldn't help but complain to Liu Hua on the road. His colleagues who went to the legal department a few years ago are now almost wearing Mediterranean hair, hahaha.

After the two left, Bai Song thought about it and realized that there was nothing wrong. He told Captain Zhao and went to the archives room.

If someone told you that there is a martial arts secret book here, and you can become a master after learning it, would you be willing to learn it?

However, if there is a bookshelf here, there are mathematics and physics books starting from the four arithmetic operations, all the way to Fermat's last theorem, group theory, Bohr, Schrödinger, and Heisenberg. Then someone will tell you, they are all Once you learn it, you will become a scientist. Are you willing?

I think there are very few people willing to do it.

What Bai Song is doing is actually the latter.

The Ma detachment handles many cases. There are dozens of books here, and there are hundreds of books later that were actually investigated by him, but they should have been bound by others, and they don't look so neat.

There was an interesting case here that caught Bai Song's attention.

This was a burglary case with a loss of 20,000 yuan. When this case was reported, there was an interval of up to two years from the time of the incident, and it took several months to file the case.

To put it simply, the old lady had 50,000 yuan in cash and was worried about where to put it, so she hid it behind the heater at home and always felt at ease.

This lasted for two years, and the old lady told no one. Later, the old lady finally realized that it was not safe to put money in this way, and was going to go to the bank to make a deposit. She put all the money that fell to the bottom of the heater from behind the heater into a bag, and went to the bank to deposit money.

The bank got the money and told the old lady that after counting, it was 30,000 yuan. Do you want to deposit it all?

The old lady said it was 50,000 yuan. The two parties couldn't agree and called the police.

After the police arrived at the scene, they found that it was indeed 30,000 yuan. After watching the surveillance video, the money handed in by the old lady was indeed 30,000 yuan after sorting it out. There was no problem. The old lady called the police and said that someone had stolen from her home.

At first, the people at the police station felt that the old lady had a bad memory, but the old lady brought her old bankbook, which indeed contained 50,000 yuan, and she had withdrawn it as cash two years ago.

As a result, four teams investigated the scene.

Nothing could be found. Even if it was stolen, it may have been two years, so everyone was suspicious of this matter, so no case was ever filed.

The standard for filing a case is also quite easy. If a crime has occurred, the suspect should be held criminally responsible and has jurisdiction. However, in this case, the old lady's words alone cannot determine that a crime has occurred.
