Retracing the Police Path 1993

Liu Pengcheng looked at the policemen in the room as if they were facing a big enemy, and said with a smile: "I intervened late in this case, so I will treat it as a transfer student and understand the progress with you old students."

Everyone relaxed.

Liu Pengcheng looked at the content he recorded in the notebook, and the first question was: "Just now the trace inspection said that no traces were found indoors and outdoors, let's not talk about the indoors, what does the outdoors mean? Is there no traces found on the first floor to the 15th floor, or Is it just that there are no traces found on the first floor? Or are there no traces found outside the windows on the first floor and the 15th floor?"

The technical inspection immediately said: "This is because no traces were found outside the windows on the first floor and the 15th floor."

Liu Pengcheng nodded and wrote it down in his notebook.

Then I asked a second question: "How did you come to the conclusion that the suspect entered through the toilet window?"

The technical inspection immediately said: "Because the victim's home has air-conditioning, the windows are closed when sleeping, until we entered the scene, the windows were still closed, only the bathroom window was open, and the victim It is said that they usually open this window when they sleep at night, and only close the screen window. At the same time, they close the door of the bathroom. It means to let the smell out."

Liu Pengcheng asked again: "Is this the case in their family, or is it the same for all the families in this building? Why did the suspect choose Dr. Zhao's house to commit the crime? Or, do these victims' homes have anything in common? For example, All have a window that can be opened? For example, are they all on the side of the building? Is there any statistics on this?"

Everyone, you look at me, I look at you, no one speaks.

Team Zhao said, "Director Liu, what do you mean they are all beside the building?"

Liu Pengcheng said: "Officer Gu, please explain to everyone."

Xiaogu reacted for a while before realizing that he was calling him, and he didn't have stage fright, but was a little excited.He stood up directly, combined with his movements, and talked about the climbing of the building.

Not to mention, what he said with gestures and gestures has a very good effect, and everyone is stunned.

Team Zhao asked, "Officer Gu, are the other buildings like this too?"

Xiaogu said: "Today, my leader and I visited five sites. Some of them can be climbed directly, but there are decorative tiles on the lower floors, which can't work and are too slippery. There are also many balconies that have been sealed. It doesn’t work even if it’s broken, and the location where we see the victims on the five floors is also in the side unit.”

Another policeman asked, "Now those who live in high-rise viewing rooms are in relatively good conditions. Most homes have air-conditioning. How about climbing up the air-conditioning unit?"

Xiaogu said: "If they are Chunlan, Gree, Mitsubishi and other regular manufacturers, it should be no problem to install after sales, but the brackets of small factories are enough to hold an adult."

Who can guarantee that the air conditioners in the building are all big brands!It's a big brand, who can guarantee it's true!The policemen shook their heads.

Seeing that everyone was okay, Xiao Gu sat down.

Liu Pengcheng continued to ask at this time: "Now it is basically confirmed how the suspect climbed up the stairs, so how did he get off? Is it the elevator, the stairs, or the way he climbed back?"

Team Jiang said: "We can basically confirm that it is the elevator or the stairs. There is no need to climb down the same way. It also increases the risk of encountering night patrol security guards."

Liu Pengcheng said again: "Can the time of committing the crime be determined?"

Several people shook their heads.

This kind of case is not an injury case or a robbery case, the victim knows when the crime was committed.

It's not even as good as some homicide cases, at least the approximate time of the crime can be known through the autopsy results.

Liu Pengcheng already knew the routine of their detection.

The trace inspection is done, but it is not thorough.

Then there is the investigation and visit, whether there are any strangers haunting these days.How often do your security guards patrol?

And this suspect did not follow the routine at all, so the police basically found no clues.

Liu Pengcheng asked the last question: "Brigade Jiang, do you have any thoughts on the range of suspects?"

Team Jiang said: "There are still some of them. First of all, he should be a person released from the two labors. This person is too professional and has not left us any clues. Then this person should have experience in firefighting or exterior wall cleaning, or simply that person. He is a professional snitch. In the end, he should be a local, and he is very familiar with Yuhang, because the community where he committed the crime spans three districts. There are scenic residences in the suburbs and high-end residences in the city center. Outsiders can't find these places. arrive."

Liu Pengcheng wrote it down and didn't comment.

Team Zhao waited for Liu Pengcheng to finish his memorization, and asked, "Director Liu?"

Liu Pengcheng said: "I have nothing to say, as I said, I am a transfer student, and I haven't finished watching the scene yet, but in addition to the few questions I just mentioned, I would like to remind you a few points, first, today's case , The bracelet inside the stolen goods, everyone knows. The owner said that it was inlaid with gems. But the inlaid ones were turquoise, ruby ​​and Xiuyu. It was hundreds of years old, and basically the luster of the gems could not be seen.

There is a high probability that the suspect will sell the stolen goods as gold bracelets.This can be used as a weathervane.

Second, with regard to the suspect's previous occupation, special forces and special police can be taken into consideration. Officer Gu is a scout who changed his career.

Thirdly, I look at the time when the crime happened. There was a night when three houses in different neighborhoods were stolen.

Why do you say that, because the stolen homes all have the common feature of building side units, the homes are in good condition, and there are windows to get in.

These three characteristics must be met, so this stepping point is a big project.If the spotting is wrong and the suspect climbs to the fifteenth floor and finds the windows locked, it's a lot of fun.Or after going in with great difficulty, it was found that the house was renovated and not moved in, which is not acceptable.So can we infer that his stepping on the spot and committing the crime are separate.It may have taken him a month to scout the spot, and then he concentrated on committing crimes in a week or ten days. "

Team Zhao asked, "What's the benefit of this?"

Liu Pengcheng said: "Of course, he can step on the spot calmly and commit crimes quickly. Even if he is caught and suspected when he steps on the spot, there is no problem! Then the most dangerous crimes can be completed in the fastest time. Just go to A certain location will do.”

After discussing for a while, everyone nodded, this is really possible.

The snitch's theft mode really has risks in this regard. He risked his life to climb to the tenth floor and found that no one was staying.Where are you going to reason!
Liu Pengcheng continued: "There is also the problem of transportation. My personal preference is motorcycles. Bicycles are too slow. Do you want to die?"

Team Jiang asked, "Can't it be a car?"

Liu Pengcheng said: "It is unlikely, because there are no large items among the stolen items, so it is impossible to use a car. The target of the car is also too large."

After the meeting, they had a working meal of meat buns at the Municipal Bureau, and the two started to walk back.

Xiao Gu asked: "Brother Liu, what are you doing tomorrow?"

Liu Pengcheng said: "First go to work and go through the procedures, and then continue to watch the scene."
