Chapter 192 Theft Scene
The house type of the owner's house is relatively square.
After entering the door, you walk through a hallway, which is 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.
"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 were no signs of the safe being pried open, and there was 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 spot without looking carefully.
It can be initially determined that the thief used a lockpick to open the safe through the mechanical keyhole.
Of course, this cannot rule out the possibility that the perpetrator knows the electronic password.
Then he deliberately used mechanical lock-picking to induce 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.
No burrs and a tight fit.
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 locked.
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 called repeat offenders.
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 it hands over the house."
The property manager said 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 pressure.
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.
With two houses on one staircase, Hu Yuefei's house and her neighbor's house have the same house layout.
On both sides of the elevator, door to door.
Stepping forward, Chen Yan observed carefully.
There are signs of wear on the wall near the door handle.
There seemed to be traces of chewing gum sticking to the cat's eyes.
"Let people collect the fingerprints on the security door and the material left on the cat's eye for technical analysis."
…
The living room of Hu Yuefei's house.
"Are you sure that only 30,000 yuan was lost? Are there any gold jewelry?"
Hu Yuefei nodded: "We don't use this safe often."
"The things inside are some spare cash and some jewelry that my husband bought 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 aren't these things put in the safe?"
"These are things I use often, so naturally they are placed outside."
Hu Yuefei stretched out her hand and showed Chen Yan the ring on her hand: "The jewelry placed in the safe are all gold bracelets and necklaces with relatively large grams."
"I don't usually wear them. They are basically financial products."
"Approximately how much is it worth?"
"There are two gold bracelets weighing about 100 grams each, and three necklaces weighing about 200 grams each. They cost probably more than 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, could you please tell me the information in your safe file bag and what's in that small box?"
"Oh," Hu Yuefei nodded: "Of course it's convenient."
"In the file bag, there are security information that I once designed."
"Inside the box is a key."
Security information?
Key?
Chen Yan frowned slightly: "Where is the security information, and what is this key used for?"
"The data is the security information I have designed for some units, such as schools, companies, etc."
It turns out that this Hu Yuefei is 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.
"As for the key, it belongs to my husband."
Chen Yan looked at the man next to Hu Yuefei.
He is probably in his 30s, well-dressed, and has an extraordinary appearance.
"Mr. Wu, could you please tell me what this key is..."
Wu Kaiyue, the male owner of the house, had been listening carefully while Hu Yuefei was answering Chen Yan's questions and did not interrupt: "This is something from our company."
"It was just delivered to me yesterday."
"It's an opening key. The specific situation involves business 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 City, and Wu Kaiyue's company is responsible for the exhibition.
Leave the Imperial Family Community.
Chen Yan and others returned to the Second Detective Squadron.
This time, although the system did not provide any reward prompts for solving the case, Chen Yan still attached great importance to this case.
The value of the lost property of the owner's family is not low, and the other party's methods are very sophisticated.
There were basically no traces left at the scene.
Fingerprints, not found.
No footprints were collected.
Moreover, the time the other party committed the crime was very short.
At most, only 45 minutes.
From opening the security door, then opening the safe, stealing things, and leaving...
And, the weirdest thing is that no camera caught the perpetrator.
You know, after Chen Yan's survey just now, the community cameras basically have no blind spots.
Especially at the entrance and exit, there is no suspicious person in the video.
other side……
How on earth is it done?
