The tool of crime is the most important physical evidence in a criminal case, and it is also one of the means to investigate suspects. Pen % fun % Pavilion www.biquge.info

As soon as this jewelry theft case came out, the entire Zhongyun City was in a sensation, and all the police forces were mobilized.

The sooner the case is solved, the more the administrative efficiency of Zhongyun City can be withdrawn, and the rest of the small criminals will be severely deterred.

Look~ Even the theft of Daimeng's jewelry, this unheard of high-tech crime has been solved. You fools who only know how to take a hammer and wear a helmet, and you still expect to challenge the ability of the Zhongyun police?

If the case drags on for three to five months, not only will the city's image be damaged, but I am afraid that the entire Zhongyun City stores dealing in valuable goods will be terrified.

With Wanbo City as the center, all the surveillance footage within a radius of several kilometers was retrieved.

Mobilize all forces to conduct a detailed investigation of the video.

This group of bold thieves can accurately find out the warehouse, paralyze all the safety devices, must have stepped on the point in advance, or there is a possibility that an acquaintance committed the crime.

If there is a pre-stepping point, then the previous video will definitely capture the clues.

The collapsed hole was one meter wide and one meter high, and Zhang Zhitong bent down to drill into the hole.

The scene inside is difficult to relate to the previous crime scene where ten brute bulls took turns to rush through.

For there is no sign of any room being turned upside down, except for the storeroom where the jewels are stored.

Daimeng Jewelry Processing Factory is an independent two-storey factory, which has been meticulously renovated before Daimeng Jewelry moved in.

The door is a Class A electronic security door, from the entrance to the various storage rooms, all this kind of security door. All windows are inlaid with sturdy anti-theft nets. In the evening, when the workers leave work, the vibration alarm device will be turned on.

In order to prevent the security guards from stealing or being attacked by thieves. The boss of Daimon Jewelry put the monitoring room in the company in the city, which means that there is no one in the factory at night.

Before getting off work, the boss of Daimeng Jewelry will personally check the jewelry warehousing work, and the picture of the remote monitoring room last night is also normal, and there is not even a shadow of a mouse.

This defense, in fact, has achieved the extreme of a jewelry company of his size.

But I didn't expect this gang of thieves to do even more extreme than him, from the outer wall closest to the warehouse, after breaking the gap. This gang of thieves doesn't have any extra probe, and there is no kind of unprofessional thief rummaging through boxes and cabinets.

They went straight to the jewelry storage warehouse, and with a method that the criminal police could not understand for the time being, they made a large hole in the side of the warehouse, and ransacked all the safes inside.

When Zhang Zhitong walked into the jewelry warehouse, several technical criminal investigation police officers were extracting fingerprints and footprints in the room. Empty, as open as a door, to the insurance, shows how ridiculous these safety precautions are.

On the front of each safe, there are two coin-sized holes around the holes with traces of melting.

It was these round holes that completely lost the five huge safes.

A female policeman stood up and said to Zhang Zhitong in a low voice: "Zhang Ke, I have a bad premonition. No fingerprints of outsiders were taken at the scene, they were all the owner's own. ”

"There were no footprints either, and it is likely that the suspect had put something on his shoes beforehand. ”

"They are so well prepared, then they will definitely make careful arrangements for the route of retreat and sale of stolen goods. If we want to catch them, we can only rely on luck. ”

Zhang Zhitong didn't speak, she squatted down with her pants and carefully examined the two round holes in the safe.

About half a year ago, the door of the treasury of the Silver Palace Club left a deep impression on her. Neither flame cutting nor plasma cutting could destroy the imported vandal door.

These safes are traditional safes with mechanical cipher discs and key locks. According to the feedback from the manufacturer, their safe also has the ability to prevent flame cutting.

Plasma cutting can be broken, but a plasma cutting device is bigger than a safe, and it is impossible to move in through the hole.

And with only two coins in the big round hole, how do you open the safe?

In the afternoon, Zhang Zhitong returned to the bureau and exchanged clues with other departments.

The traffic department has not found anything for the time being, and the surveillance video has not found any abnormal personnel. Wanbo City is mainly composed of building materials companies, and at three o'clock in the morning, there is not even a ghost. The police interviewed all the people inside and did not obtain a single valuable sighting report.

There was no gain in terms of intelligence, and the local prison oil reformers and informants all shook their heads and said that this group of people is too professional, and we are not from the same world as him, so we can't get together.

The net police gained the most, and they found the reason why the alarm and internal monitoring were not working.

The external connection was cut by someone, and the suspect also used a laser to irradiate the camera to prevent video backup in the factory for the sake of safety.

If thread cutting is not a technology, then what happened in the remote monitoring room in the city taught all the police officers an ideological education lesson.

The factory's remote monitoring room was hacked a week ago.

Not only did the suspect observe everything that happened in the factory at will, but on the night of the theft, he had the monitor play a replay of yesterday's footage.

There was no theft yesterday, and it was natural that everything was normal in the replay.

The suspect can watch the factory monitoring at will, and naturally he has all the layout and monitoring locations in the factory. Then it is possible that it was not an acquaintance who committed the crime, which suddenly complicated the whole case.

"I turned out to watch those spy and thief movies, and I laughed at those directors for opening their brains too much. A criminal policeman spat out a string of smoke rings hatefully: "reality is more bizarre than the movie, look at this, this case is not solved." Promise that it won't be long before they commit another crime. ”

"Now that the news from all the major Internet is coming out, we are the headlines, and countless Canadian media have called to interview us. ”

"Xiao Zhang, what do you think?" Director Zuo of the Municipal Bureau re-lit a cigarette and coughed: "The provincial department has replied that there is no similar case in this case in China, and it is basically certain that this group of people is committing a crime for the first time." ”

"According to the information obtained at the scene, the suspects' methods are heinous in their professional methods. Brains, knowledge, and action. The tools used to commit crimes are also things that we have never touched. ”

Zhang Zhitong kept turning the recording pen in his hand: "I think we should change our thinking." ”

"This group of people is probably not the lawless and psychologically distorted gangsters in the traditional sense. ”

"Rather, it is a group of people who have a strong ability to make a living in society, and certain economic conditions, and have skills related to industrial processing. ”

Zhang Zhitong's beautiful eyes shot out two determined rays of light: "A layman, it is absolutely impossible to break through two solid concrete walls in a short period of time, let alone break the safe with anti-cutting function. ”

"And the tools used in this are certainly not ordinary. ”

"I suggest that we focus on those machinery factories and investigate the machinery factories in the city. (To be continued.) )
