Chapter 191： Theft scene

The house type of the owner's house is relatively square.

After entering the door, walk through a hallway, which is the living room.

The area is about 40 square meters.

This is a large flat.

Floor-to-ceiling windows occupy one side, allowing for good lighting.

Opposite the TV background wall is the wall inlaid with the safe.

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

Zhang Chaoyang followed behind Chen Yan: "There is no mechanism set up, open the oil painting, it is a safe."

Chen Yan nodded and began to check the scene.

The safe is a relatively common electronic lock safe.

Usually, the safe is opened by entering the password.

And there is a spare mechanical key.

This kind of safe is more common in the market and is a general private safe.

Of course, ordinary people can't open it, but if you put it in the hands of someone with unlocking skills, it's basically no difficulty to open this kind of safe.

On the floor, there are scattered filing bags, and there is a small box inside the cabinet.

The box is more delicate, with a combination lock on it.

And a diary, nothing else.

Putting on gloves, Chen Yan carefully observed the safe.

The visual gene lock is on.

The safe has no signs of being pried open, and the surface is not damaged.

Thieves should use mechanical keys or electronic passwords to directly open the safe and carry out 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 specific situation cannot be seen outside.

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

There are slight metal scratches that are hard to spot without careful observation.

It can be preliminarily determined that the thief should have used a lock-picking tool to open the safe through a mechanical keyhole.

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

Then deliberately use the mechanical unlocking method to induce the detectives.

"How is the fingerprint information collected?"

Zhang Chaoyang shook his head: "Fingerprint collection has ended."

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

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

There are about a dozen portfolio belts, each with a seal attached.

Chen Yan picked up the portfolio and observed it carefully.

All portfolio seals are no problem.

No burrs and a tight fit.

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

A notebook is a ledger with some digital information recorded in it.

On the small box is a simple mechanical combination lock.

Chen Yan tried to open it, but it didn't work.

Obviously, the combination lock is in the locked state.

Then, Chen Yan came to the entrance door.

If a thief wants to enter a room and steal, the first thing that needs to be solved is the entrance door.

The entrance door of Hu Yuefei's house is obviously more upscale.

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

"Verify the unlock by entering a password or fingerprint."

"Of course, there are also mechanical locks that can be opened in an emergency."

Chen Yan nodded.

Now some high-end residential security doors are basically this kind of relatively advanced electronic door locks.

In the same way, Chen Yan himself observed the mechanical keyhole of the security door.

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

The mechanical shrinkage position of the entrance door is very smooth, and there are basically no traces of use or touch.

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

This is certainly a possibility.

Burglary, although many are called repeat offenders.

But the situation where the thief shouts to catch the thief, is there?

Of course there is.

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

Taking a step back, Chen Yan closed the entrance door and observed again.

The facade is neat and tidy with no signs of vandalism.

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

Chen Yan turned to look at the security door of the neighbor opposite.

The same is true.

Both entry doors are the same in style, color and branding.

"The entrance door is uniformly customized when the developer delivers the house."

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

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

"Hand me a blade."

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

Snap the blade into the edge of the cat's eye cavity, using gentle pressure.

click.

The cat's eye was snapped off.

At the edges, the paint wear marks can be clearly seen.

"A thief opened a security door through a cat's eye?"

Seeing Chen Yan's actions, Zhang Chaoyang guessed one or two.

Opening the anti-theft door through the cat's eye is a new type of unlocking method that has appeared recently.

Not only thieves, but also the staff of some unlocking companies do the same when opening the electronic lock anti-theft door.

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

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

There is also a button type, 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 buckled the cat's eye, he basically confirmed the previous guess.

Chen Yan nodded: "It's basically certain that the other party used a special hook to open the security door through the cat's eye."

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

With one ladder and two households, Hu Yuefei's house and the neighbor's house are the same.

On both sides of the elevator, door to door.

Stepping forward, Chen Yan carefully observed.

There are signs of wear and tear on the wall near the door handle.

On the cat's eyes, there seem to be traces of chewing gum sticking.

"Let people collect the fingerprints on this security door and the leftover material on the cat's eye for technical analysis."

...

Hu Yuefei's living room.

"Are you sure that only 30,000 yuan is lost, and is there any gold jewelry?"

Hu Yuefei nodded: "We don't often use this safe."

"The things in it are some spare cash, and some jewelry that my husband bought for me in the past."

"Ms. Hu, I just found a jewelry box on the table next to your safe. There are also some gold rings or necklaces and earrings in it."

"Why aren't these things in the safe?"

"These are the ones I use often and are naturally kept outside."

Hu Yuefei stretched out her hand and showed Chen Yan the ring on her hand: "The jewelry in the safe are all gold bracelets and necklaces with relatively large grams."

"I don't usually wear it, and it's basically a financial product."

"How much is it worth?"

"There are two gold bracelets of about 100 grams, and three necklaces of about 200 grams, about 200,000 yuan."

Hundreds of thousands of gold jewelry, plus 30,000 yuan in cash.

The loss is not small.

"By the way, Ms. Hu, it is convenient to talk about the information in your safe file bag, and what is in that small box?"

"Oh," Hu Yuefei nodded, "Of course it's convenient."

"In the file bag, there are security materials that I once designed."

"In the box is a key."

Security information?

key?

Chen Yan frowned slightly: "Where is the security information, and what does this key do?"

"The information is the security information I once designed for some units, such as schools, companies, etc."

It turned out that this Hu Yuefei was the safety designer of Liancheng Taiping Insurance Company.

This is Hu Yuefei's habit. She will keep a backup of every security design she makes.

"As for the key, that's my husband's."

Chen Yan looked at the man beside Hu Yuefei.

About 30 years old, well-dressed and extraordinary.

"Mr. Wu, it's convenient to say that this key is..."

Wu Kaiyue, the male owner of the house, had been listening carefully when Hu Yuefei answered Chen Yan's question, without interrupting: "This is something of our company."

"It was just delivered to me yesterday."

"It's an opening key, the specific situation involves trade secrets..."

It turned out that Wu Kaiyue was an executive of an exhibition company.

Next week, there will be a Chinese painting exhibition in Liancheng, and Wu Kaiyue's company will be in charge of the exhibition.

Leave the Imperial Family Community.

Chen Yan and others returned to the 2nd Detective Unit.

This time Although the system does not have any reward reminders for solving the case, Chen Yan still attaches great importance to this case.

The financial value lost by the owner's family is not low, and the other party's methods are very old-fashioned.

There were basically no traces left at the scene.

Fingerprints, not found.

Footprints were also not collected.

Moreover, the time for the other party to commit the crime is very short.

At most, only 45 minutes.

From opening the security door, then opening the safe, stealing things, leaving...

Moreover, the most bizarre thing is that there is no camera to capture the perpetrator.

You know, after Chen Yan's investigation just now, the community cameras basically have no dead ends.

Especially in the import and export, there is no suspicious person in the video.

other side……

How exactly?
