Chapter 192 Theft scene

The house of the owner's house has a relatively square layout.

After entering the door, you walk through a hallway and you are in the living room.

The area is about 40 square meters.

This is a large flat floor.

Floor-to-ceiling windows occupy one side and provide good lighting.

Opposite the TV background wall is the wall with a safe built into it.

"The outside of the safe was originally covered with an oil painting."

Zhang Chaoyang followed Chen Yan: "There is no mechanism, just open the oil painting and it will be a safe."

Chen Yan nodded and began to inspect the scene.

The safe is a relatively common electronic lock safe.

Normally, the safe is opened by entering the password.

And there is a mechanical key as a backup.

This kind of safe is more common on the market and is a general personal safe.

Of course, ordinary people cannot open it, but if it is placed in the hands of someone with lockpicking skills, it is basically not difficult to open this kind of safe.

There are scattered file bags on the floor and a small box inside the cabinet.

The box is relatively delicate and has a combination lock on it.

There is also a diary, but not much else.

Putting on gloves, Chen Yan carefully observed the safe.

The visual gene lock is opened.

There are no signs of the safe being pried open, and there is no surface damage.

The thief should use a mechanical key or electronic password to directly open the safe and commit theft.

"Give me the flashlight."

Zhang Chaoyang handed the flashlight to Chen Yan.

The mechanical keyhole of this safe is inside the cabinet, and the details cannot be seen from the outside.

Through the flashlight, Chen Yan could clearly see the expression on the keyhole.

There are slight metal scratches, which are difficult to detect without looking carefully.

It can be preliminarily determined that the thief used a lockpick to open the safe through the mechanical keyhole.

Of course, this cannot be ruled out that the perpetrator may know the electronic password.

Then he deliberately used a mechanical lock to lure the detectives.

"How was the collection of fingerprint information?"

Zhang Chaoyang shook his head: "The fingerprint collection is over."

"Except for the owner Hu Yuefei and his husband, no other person's fingerprints were found."

Chen Yan nodded, squatted down, and looked at the portfolio on the ground.

There are about a dozen portfolio bags, each with a seal.

Chen Yan picked up the file bag and observed it carefully.

There is no problem with the seals of all portfolios.

There are no burrs and the fit is tight.

After observing carefully for a moment, Chen Yan picked up the notebook and small box in the safe.

A notebook is an account book with some numerical information recorded in it.

On the small box is a simple mechanical combination lock.

Chen Yan tried to open it, but failed.

Obviously, the combination lock is in a locked state.

Then, Chen Yan came to the entrance door.

If a thief wants to enter a room and steal, the first thing he needs to solve is the entrance door.

The entrance door of Hu Yuefei's house is obviously relatively high-end.

"Team Chen," Zhang Chaoyang put on his gloves and pointed at the door lock: "The home security door of the owner's home is a fully automatic electronic lock."

"Verify unlocking by entering password or fingerprint."

"Of course, there are also mechanical locks that can be opened for emergency use."

Chen Yan nodded.

Nowadays, the entry security doors in some high-end residential areas are basically this kind of relatively advanced electronic door locks.

Using the same method, Chen Yan himself observed the mechanical keyhole of the security door.

However, it is different from scratches around the mechanical keyhole of the safe.

The mechanical shrinkage of the entrance door is very smooth, with almost no traces of use or touch.

Could it be that the other party opened the door by entering a password?

This is certainly a possibility.

Burglary, although many are habitual offenders, is so called.

But is there ever a situation where a thief calls out to catch a thief?

Of course there is.

Or it is possible that the owner leaked the password through other means.

Stepping back, Chen Yan closed the entrance door and observed again.

The facade is clean and tidy, with no signs of damage.

In the center, there is a cat's eye.

Chen Yan turned around and looked at the neighbor's security door opposite.

Same thing.

The style, color, and brand of the two entrance doors are the same.

"The entrance door is custom-made by the developer when the house is handed over."

The property manager introduced on the side: "Every household is the same."

Chen Yan nodded and looked at the cat's eye.

"Hand me a blade."

Zhang Chaoyang asked someone to find a blade and give it to Chen Yan.

Insert the blade into the edge of the cat's eye cavity and apply gentle force.

Click.

The cat's eye was pulled down.

At the edges, traces of paint wear can be clearly seen.

"The thief opened the security door through the peephole?"

Zhang Chaoyang guessed a thing or two when he saw Chen Yan's movements.

Opening security doors through peepholes is a new unlocking method that has appeared in recent times.

Not only thieves, but also the staff of some locksmith companies do this when opening electronic lock security doors.

There are two ways to open the fully automatic electronic anti-theft lock internally.

One is to lift the door handle and open the door.

There is also a push-button type. When the button is pressed, the door lock will open naturally.

When Zhang Chaoyang saw that there were obvious signs of wear and tear after Chen Yan buttoned up the cat eye, he basically confirmed his previous guess.

Chen Yan nodded: "It's basically certain that the other party opened the security door through the peephole and using a special hook."

After checking twice, Chen Yan turned around and walked towards the opposite side of the door.

The layout of the two-family house on one staircase is the same as that of Hu Yuefei's house and her neighbor's house.

On both sides of the elevator, door to door.

Stepping forward, Chen Yan observed carefully.
