Li Yi wiped the whiteboard on the wall clean. This was one of his habits. Every time he started to prepare to discuss the case, he would record the key points and key people on the whiteboard, and then repeatedly verify their mutual relationship and mutual involvement.

Until the equal sign is drawn.

Qin Gang is different from him. He likes to draw mind maps on the computer. The most important thing is that he doesn't like to wipe the whiteboard.

Qin Gang brought the file, and Li Yi stood in front of the whiteboard to read it.

"The shoe prints at the scene are the same person as the shoe prints at the previous burglary cases. The technical team analyzed that this guy is about 175-180cm tall. In the previous times, traces were only collected at the scene, and there was no relevant information in the surrounding surveillance.

I found out, but this time the security surveillance was very effective, the picture was very clear, and the face was straight, which shows that he is not a smart thief, so he showed his face." Qin Gang said.

Li Yi first briefly browsed through several recent related cases. The time period before and after the occurrence was no more than 3 months. The locations he chose to commit the crimes were all high-rise buildings in the community. He sneaked into the top-floor residents from the rooftop in the middle of the night, then stole, and then escaped through the door. The residents were all in

I woke up in the morning and found out that it had been stolen, but not much of my belongings were missing.

It's just that this method is quite difficult. Li Yi thought about the operation of descending from the ceiling of a building to the balcony. Even if he didn't do it himself, his feet would feel a little shaky. Moreover, he committed five crimes in three months. Such frequent crimes were...

I'm really not afraid of falling to death.

Li Yi wrote on the whiteboard: habitual offender.

"What kind of brain circuit does this guy have? Use this method."

"It's hard to say. The multi-molecule complex structure of humans is too complex. Some people use their brains, some people use their cerebellum, and some people may think with their toes. I don't rule out that there are also people who think with their butts. There is another possibility, maybe

It’s just that those who are good at art are bold and challenge the difficulty, unlike the two of us, who avoid the difficulty.” Qin Gang burst into laughter.

Li Yi continued to write at the bottom of the whiteboard: My head may have been caught by the door. After thinking about it, I thought it was inappropriate and erased it.

"Judging from the previous four cases, the financial losses were not large, and the lost cash was not much. It was just the loss of mobile phones and laptops. I guess there is really nothing to steal, and mobile phones and laptops were easily taken away. Mobile phones can be sold.

Two or three hundred dollars is not bad, but laptops are really hard to sell, so you have taken risks and gained little, and you are considered a stupid thief." Qin Gang said.

Li Yi wrote on the whiteboard: The reason for frequent crimes is that the profit from each theft is not high.

This method of committing a crime was similar to a similar case in a southern city many years ago. The thief also sneaked up to the rooftop and hid there until midnight, then sneaked into the household through the rooftop. He thought that the owner would be asleep at midnight, but

Unexpectedly, the owner of the house was not sleeping, so he happened to bump into the house. The thief drew a knife in desperation, and the theft turned into a murder.

When the murderer escaped, he actually took the elevator. It didn't take much to solve the case, but this kind of crime method was indeed rare. From Li Yi's point of view, even the adrenal glands and the brain would not choose this kind of movie plot.

method to commit theft.

"Why did he have to choose such a high-rise building without an elevator? An old-fashioned building with seven or eight floors would be fine. At least the height looks down-to-earth and won't feel so intimidating." Qin Gang asked.

Ask a question.

Li Yi looked at the whiteboard and thought for a moment, "People have a habitual understanding of the world. For example, if you see a big man with a beard and convex muscles, what will your subconscious think of this person? Generally

You will all feel that this person will be very fierce and a bit difficult to mess with. How would you feel if he had tattoos on his arms? He must be a social person, right?"

Qin Gang nodded.

"Similarly, which one looks more expensive: a house, an old-fashioned building with seven or eight floors without an elevator, or a building with twenty or thirty floors with an elevator?"

"Visually it is definitely the latter."

"So, if you want to steal something, in a forest full of steel bars and concrete, you have to choose a house that looks more expensive. The concept is very simple. If the house is expensive, the people who live in that house are theoretically well-off.

People, this is a kind of inertial perception. Of course, people who live in villas will be richer, but it is not very maneuverable. There are no villas in the city, and it is difficult for an ordinary thief to travel to areas with villas in traffic;

Besides, at night, it’s dark, and it may feel the same whether it’s 20 meters or 100 meters away from the surface, so if you don’t believe me, give it a try.”

"The inferences are all reasonable. I just think this method is a bit stupid. If you want to do this, you have to practice rock climbing first, otherwise you won't be able to do it," Qin Gang said.

"Not necessarily. I like to use a whiteboard to deduce the case. You like to use mind maps on the computer to deduce the case. The preference may be said to be just a habit. It is not because I am good at drawing or writing, nor is it because you are good at thinking.

How proficient are you in using mapping software?”

Li Yi went through the information on the East Lake case carefully.

The case does not seem to be complicated. East Lake Community, an early high-end real estate in this city, is next to East Lake Avenue, on the edge of Zhengdong Lake. There is a row of willow trees by the lake. You can see the lake through the window, and you can hear the willow waves and the orioles. It is a legendary ecological negative ion oxygen-enriched building.

community.

The victim, Ms. Lin, is a 31-year-old housewife who has lived in the community for 5 years. Her husband is engaged in selling medical equipment and travels away from home all year round. He was on a business trip on the night of the incident.

The murderer sneaked in to steal at night and woke up Ms. Lin, so he drew a knife and stabbed Ms. Lin, then opened the door and fled without a trace. The thief was quite smart and did not take the elevator and slipped away through the fire escape, but entered the underground parking lot.

Although the camera in the basement was blurry, the figure was still recorded. What is important is the evidence of the time.

Ms. Lin reluctantly called the property management company to call for help. She lost a lot of blood at that time. Fortunately, she was treated in time. She had stab wounds on her face, hands, shoulders, and body. She was not in danger of life. She was just overly frightened and her face was scratched.

I was hurt, my mood has been unstable, and I have never recorded it.

Is it really as Team Liu said: not difficult?

Li Yi didn't think so in his heart. Qin Gang said that there were doubts in this case.

"If we just look at the process before and after, it feels like we have nothing to do. We can just wait for the co-investigation report. Everyone's face has been exposed and there is no escape. But the evidence at the scene..." Li Yi said half of his words.

"You have ideas too, right? I think we both have the same idea." Qin Gang understood what Li Yi wanted to say.

"I still have to go and see the scene. I haven't walked through the scene, and I always feel like there is something missing." Li Yi said.

"It's necessary. If you finish sorting out the information, we will go to the hospital to make a record first, and then go to the scene when we come back. Don't worry, you can scan it carefully again to see if you can smell something else." Qin Gang picked up the whiteboard marker,

A big question mark was drawn on the whiteboard.

"By the way, yesterday I accompanied the victim's husband back to the scene and asked him to roughly check out various items in the house. There was nothing missing. It seems that this thief is not stupid. He has committed the crime five times, and his modus operandi is quite similar.

It's a difficult job that ordinary people can't do, but there is no reward. The only thing is that he has never found his wife, Ms. Lin's car key. I went to the basement to look at it, and the car was still there. I guess it was too confusing at the time and I didn't know where to find it.

I went there, and then I went home and looked for a spare key in the cabinet."
