Chapter 191: The scene of the theft
The house type of the owner's house is relatively square.
After entering the door, walk through a porch, which is the living room.
The area is about 40 square meters.
This is a large flat.
Floor-to-ceiling windows occupy one side, and the lighting is very good.
Opposite the TV background wall is the wall inlaid with a safe.
The outside of the safe was originally covered with an oil painting.
Zhang Chaoyang followed behind Chen Yan: There is no mechanism setting, just 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 a password.
And there is a mechanical key for backup.
This kind of safe is relatively common in the market, and it is a general private safe.
Of course, ordinary people can't open it, but if it is in the hands of someone with lockpicking skills, it is basically not difficult to open this kind of safe.
On the floor, there were scattered file bags, and there was a small box inside the cabinet.
The box is more delicate, with a combination lock on it.
There is also a diary, and nothing else.
Putting on his gloves, Chen Yan carefully observed the safe.
The vision gene lock is on.
The safe showed no signs of being pried open, and the surface was 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 key hole of this safe is inside the cabinet body, and the specific situation cannot be seen from the outside.
Through the flashlight, Chen Yan could clearly see the condition of the keyhole's expression.
There are slight metal scratches, which are hard to spot without looking carefully.
It can be preliminarily determined that the thieves should have opened the safe through a mechanical lock hole with a lockpicking tool.
Of course, this cannot be ruled out, the perpetrator may know the electronic password.
Then deliberately use the method of mechanical unlocking to lure the detectives.
How is the fingerprint information collection?
Zhang Chaoyang shook his head: The fingerprint collection has ended.
Except for the owner Hu Yuefei and his husband, no other fingerprints were found.
Chen Yan nodded, squatted down, and looked at the portfolio on the ground.
There are about a dozen file bags, and each file bag is sealed.
Chen Yan picked up the file bag and observed it carefully.
All the seals of the file bags are no problem.
No rough edges, fit snugly.
After observing carefully for a while, Chen Yan picked up the notebook and the 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 failed.
Obviously, the combination lock is locked.
Then, Chen Yan came to the entrance door.
If thieves want to enter the room and steal, the first thing they need to solve is the entrance door.
The entrance door of Hu Yuefei's house is obviously relatively high-end.
Captain Chen, Zhang Chaoyang put on his gloves and pointed to the door lock: The owner's home security door is a fully automatic electronic lock.
Verify unlocking by entering a password or fingerprint.
Of course, there are also mechanical locks for emergency opening.
Chen Yan nodded.
Nowadays, the anti-theft doors of 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 the scratches around the mechanical lock hole of the safe.
The position of the mechanical shrinkage hole 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 door by entering a password?
This is certainly a possibility.
Burglaries, though many are so-called habitual offenders.
But is there a case where a thief shouts, Stop a thief?
Of course there is.
Or the owner leaked the password through other means, it is also possible.
Taking a step back, Chen Yan closed the entrance door and observed again.
The facade is clean and there are no signs of damage.
In the center, there is a cat's eye.
Chen Yan turned his head and looked at the security door of the neighbor opposite.
The same is true.
Both entry doors are identical in style, color, and brand.
The entrance door is uniformly customized when the developer delivers the house.
The property manager introduced on the side: Every household is the same.
Chen Yan nodded and looked at the cat's eye.
Pass me a blade.
Zhang Chaoyang asked someone to find the blade and handed it to Chen Yan.
Snap the blade into the edge of the cat's eye cavity with light pressure.
click.
The cat's eye was shut down.
At the edges, traces of paint wear can be clearly seen.
The thieves opened the anti-theft door through the peephole?
Seeing Chen Yan's actions, Zhang Chaoyang guessed a thing 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 also operate in the same way when opening the electronic lock anti-theft door.
There are two ways to open the fully automatic electronic anti-theft lock inside.
One is to lift the door handle and the door opens.
There is also a button type, the button is pressed, and the door lock opens naturally.
When Zhang Chaoyang saw that there were obvious signs of wear and tear after Chen Yan closed the cat eye, he basically affirmed his previous guess.
Chen Yan nodded: It is basically certain that the other party opened the anti-theft door through the cat's eye and using a special hook.
After checking twice again, Chen Yan turned around and walked to the opposite side of the door.
The house type of Hu Yuefei's house and the neighbor's house are the same for the house type of two houses on one floor.
On both sides of the elevator, door to door.
Stepping forward, Chen Yan observed carefully.
The wall near the door handle has scuff marks.
On the cat's eyes, there seemed to be traces of chewing gum sticking.
Have someone collect the fingerprints on the anti-theft door and the remaining substances on the cat's eyes for technical analysis.
...
The living room of Hu Yuefei's house.
It is confirmed that the only thing missing is 30,000 yuan. Is there any gold jewelry?
Hu Yuefei nodded: We don't use this safe very often.
The things in it are some spare cash, and some jewelry that my husband bought for me before.
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 haven't these things been put in the safe?
These are the ones I use often, so they are naturally placed 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 a relatively large weight.
I don't usually wear it very much, and it is basically a financial product.
How much is it worth?
There are two gold bracelets weighing about 100 grams, and three necklaces weighing about 200 grams each, costing about two hundred thousand yuan.
Hundreds of thousands of gold ornaments, plus 30,000 yuan in cash.
The loss is not small.
By the way, Ms. Hu, is it 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 have designed.
Inside the box is a key.
Security information?
key?
Chen Yan frowned slightly: Where is the security information, and what is this key for?
The information is the security information I have designed for some units, such as schools, companies, etc.
It turned out that this Hu Yuefei was the security designer of Liancheng Taiping Security Company.
This is Hu Yuefei's habit. She will keep a backup of every security design she makes herself.
As for the key, it belongs to my husband.
Chen Yan looked at the man beside Hu Yuefei.
About 30 years old, well-dressed, good-looking.
Mr. Wu, it's convenient to say that this key is...
Wu Kaiyue, the male owner of this house, had been listening carefully when Hu Yuefei was answering Chen Yan's question, without interjecting: This is something from our company.
It was delivered to me just yesterday.
It's an unlock key. The specific situation involves commercial secrets...
It turned out that Wu Kaiyue was an executive of an exhibition company.
Next week, there will be a traditional Chinese painting exhibition in Liancheng, and Wu Kaiyue's company is in charge of the exhibition.
Leave the Emperor's Family Community.
Chen Yan and others returned to the second detective team.
This time, although the system did not provide any rewards for solving the case, Chen Yan still attached great importance to this case.
The value of the property lost by the owner's family is not low, and the method of the other party is very sophisticated.
There were basically no traces left at the scene.
Fingerprints, not found.
No footprints were collected either.
Moreover, the time for the other party to commit the crime was very short.
At most, only 45 minutes.
From opening the anti-theft door, then opening the safe, stealing things, leaving...
Moreover, the strangest thing is that there was no camera to capture the perpetrator.
You know, after Chen Yan's survey just now, the cameras in the community basically have no dead ends.
Especially for import and export, there is no suspicious person in the video.
other side……
How exactly?
