Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

After entering the unit door, Lu Chuan did not enter the elevator, but followed the stairs to the stairwell between the first and second floors.

According to the surveillance situation just viewed from outside the door, there is a rainproof barrier on the unit door, which is facing the window of the walking stairwell.

If the theft suspect did not come out of the unit door after completing the theft, is it possible to climb out from the ventilation window of the stairwell between the first and second floors? In this way, it is possible to escape the surveillance at the unit door.

"We have also checked here. The windows can be opened from the inside and people can pass through, but there are no traces of stepping on them. It is very clean."

When Yuan Shaokang saw Lu Chuan going upstairs, he knew what he wanted to see.

The people in the High-tech Zone Criminal Police Brigade are not idlers either. After receiving the report, they basically checked every aspect they could think of.

Lu Chuan put on his gloves and checked the window himself. There was indeed no trace of stepping on it. There was a layer of dust floating on it, and there was no trace of any human movement.

Yuan Shaokang continued: "The owner lives on the 8th floor. We checked all the windows going down from the 8th floor, but we didn't find any clues."

"There is also the roof. The height of this building is 11 floors. You can reach the roof directly from the 11th floor."

"But if you want to go upstairs, you have to pass by the homes on the top floor. There are always people in the two homes on the top floor. It is impossible for the suspect to cross from the top floor to other units silently and leave."

"We checked the entire building and just a few exits, but nothing was found."

This is interesting.

"Let's go and have a look at the scene first."

In fact, according to what has been discovered so far, since it is impossible for the other party to come out of the building without leaving a trace, does that mean that the suspect may live in this unit?

Putting this doubt aside, Lu Chuan, Zhang Hui, and Yuan Shaokang took the elevator to the eighth floor.

"The door lock showed no signs of violent prying."

Lu Chuan took out a magnifying glass and a strong flashlight from his field survey bag.

There was indeed no sign of violent opening on the surface of the lock, but under the illumination of a magnifying glass and a strong flashlight, Lu Chuan still discovered something interesting.

"High Strength Gel."

There was a layer of bright reflection on the keyhole, and Yuan Shaokang also saw it at this moment.

"What is high-strength gel?"

He had never heard of this stuff.

Lu Chuan didn't know it before, but the intermediate spot survey skill card contains the method of using and discovering this special material.

"Just think of it as another kind of glue that is particularly hard after it dries."

"The suspect did not use violence to open the lock. He should have injected high-strength gel into the keyhole through a needle, and then waited for the glue to dry and harden, and it became a key."

Lu Chuan did not explain the other things in detail. This gel is not sold in batches and is all prepared by oneself.

How did the other party master this recipe?
According to the information Lu Chuan learned, this kind of thing is generally only used by magicians when performing.

Because this gel is transparent, it cannot be seen clearly from a distance.

Entering the room, Lu Chuan knew why the owner immediately reported the crime.

Some burglary cases are actually not very difficult to detect. The main reason is that the time when the owner discovers the theft is very late in most cases.

If something is lost, you will only know it is missing when you find it is gone when you are using it.

Normal people would not check to see if the cash is still under the bedside as soon as they get home.

But this family was different. The whole room was turned into a mess.

Clothes were scattered everywhere, the books in the bookcase were basically upside down on the floor, and even the bed was turned over. "This is really a thief."

Since joining the police, Lu Chuan has seen many murder scenes, including disgusting and terrifying ones.

But this was the first time I had seen such a messy theft scene.

"The other party didn't leave any traces?"

Yuan Shaokang nodded: "Not at all, nothing was found."

"We only collected the footprints and fingerprints of the owner, his wife and their children in the room."

"And it also rules out the possibility of self-inflicted theft."

This kind of thing has not happened before.

Yuan Shaokang had received such a report before. The owner said that money was lost at home, but it turned out that he had stolen it.

The reason is also very simple. The wife manages the money too tightly, and the husband has no choice but to steal the family's money and then call the police.

"The man was on a business trip out of town and didn't come back for a week. We have verified that he has tickets and everything. The man's employer has verified that there is no problem."

"The woman has been living at her parents' house and has never come back."

"Captain Yuan, let me take a look first."

Since the possibility of the prison guard committing theft has been ruled out, it must have been an outsider who committed the crime.

Since the suspect has been in and out of this house, he will definitely leave traces, but the other party must have taken some measures to reduce these traces to a minimum.

The fact that the people from the High-tech Zone Criminal Police Brigade didn't notice it didn't mean that Lu Chuan wouldn't find it either.

The ground is Lu Chuan's focus.

Theft is the kind of case that is repeatedly banned. It seems that no matter what the social and economic development is, theft still exists.

Moreover, theft methods are becoming more and more advanced.

The obvious point is that there are basically no cases of fingerprints being left at the scene of theft.

Almost all the stupid thieves have been caught, and the rest are relatively smart.

Know that wearing gloves when committing a crime will not leave fingerprints, and the probability of being caught is always smaller.

But it is impossible for any crime scene not to leave footprints.

There's no way the suspect could have wandered in.

Some people are thoughtful and will clean up their footprints before leaving, but this house is different. The other party did not clean the ground at the scene, but the people from the High-tech Zone Criminal Police Brigade did not collect the suspect's footprints, which is strange.

Since it was not a self-inflicted theft, and the suspect had not left any footprints, how did the other party enter the scene?How did you leave the scene?
In the room, the High-tech Zone Criminal Police Brigade has laid out transparent footboards, and the scene is well protected.

Lu Chuan lay on the ground and observed carefully.

The floor of the crime scene is made of marble tiles. If you look directly at it, you can't see anything. But if you look slightly towards the light, you can find many footprints on the side.

The footprints are messy, but there are basically only three types, which should be those of the owner, his wife and children.

There are traces of overlay on the footprints, and the covered footprints can be clearly identified.

In many cases, suspects will deliberately wear large, flat shoes without patterns in order to cover their footprints. In this case, the footprints left at the scene will act as a large pressure plane, making it difficult to detect.
