M F Chapter 449: Turn your eyes to the professional.

As soon as this jewelry theft case occurred, the entire Shanghai City was in a sensation, and all police forces were mobilized because the quicker the case would be solved, the better the administrative efficiency of Shanghai City could be realized, and the rest of the young criminals would be greatly deterred.

Look... If this theft, this unheard-of high-tech crime of the jewelry Daimeng Jewelry has been solved, those who only knew how to use a hammer and wear a mask, still expected to challenge the ability of the Shanghai police, because the tool of committing crimes is not only the most important physical evidence in criminal cases but also one of the means of investigating suspects.

If the case dragged on for three to five months, not only would the city's image be damaged, but the entire Shanghai City stores that operated valuable commodities would be frightened.

Expo City center retrieved all surveillance videos in a radius of several kilometers and mobilized all forces and conducted detailed investigations on the videos.

This group of brave thieves could accurately find out the warehouse, paralyze all safety devices, should have stepped on a bit beforehand, or maybe there was a possibility of acquaintances had committed the crime.

If they had schemed on it beforehand, the videos had been definitely captured clues previously.

The collapsed hole was one meter in width and height, and Zhang Zhitong bent over and got in through the hole.

The scene inside was difficult to relate to the previous crime scene where ten bulls rushed through it in turn, because there was no sign of being turned over in any other room except the warehouse where the jewelry was stored.

The Daimeng Jewelry Processing Factory was an independent two-story factory building. Before entering Daimeng Jewelry Factory, detailed decoration work was carried out here.

The doors were a Class A electronic security door, from the entrance to each storage room, all of this kind of security doors. All windows were inlaid with strong anti-theft nets. At night when workers left work, the vibration alarm device would be turned on.

To prevent the security guard from stealing or being attacked by thieves, the boss of Daimeng Jewelry put the monitoring room in the company in the city, which means that there was no one in the factory at night.

Before leaving, get off work, and the boss of Daimeng Jewelry personally would check the jewelry warehousing work. The picture of the remote monitoring room last night was normal, and there was no shadow of a mouse. This defense had actually achieved the ultimate in a jewelry company of his size.

But he didn't expect this group of thieves would be more extreme than him, after breaking the gap from the outer wall closest to the warehouse. This group of thieves didn't make any extra investigations; it was not the kind of non-professional thieves who ransacked the cabinet. They went straight to the jewelry storeroom, using methods that the criminals’ police had not understood, for the time being, opened a large hole in one side of the storeroom and ransacked all the safes inside.

When Zhang Zhitong walked into the jewelry storeroom, several technical criminal investigators were extracting fingerprints and footprints in the room. It is empty and open like a door to insurance, showing how ridiculous these safety precautions are.

On the front of each safe, there are two round holes the size of a coin, with traces of melting around the holes. It was these round holes the main reason for completely lost the contents of the huge safes.

A female policeman stood up, lowered her voice, and said to Zhang Zhitong: "Chief Zhang, I have a bad feeling. No outsider's fingerprints were extracted at the scene. They belonged to the owner of the jewelry company. There are no footprints either. The suspect probably put something on his shoes beforehand. They are so well prepared, so they had definitely made careful arrangements on the route of retreat and sale of stolen goods. We could catch them probably only by luck.”

Zhang Zhitong didn't speak; she crouched down with her trousers, and carefully checked the two round holes in the safe.

About half a year ago, the warehouse gate of the Silver Palace Club left a very deep impression on her. Neither flame cutting nor plasma cutting can destroy the imported riot door.

These safes in front of her were traditional safes with mechanical code disks and key locks. According to the information provided by the manufacturer, their safes also had the ability to prevent flame cutting and Plasma cutting could not break it, but plasma cutting equipment, it's bigger than a safe, and it's impossible to move it in through the hole, so how did they open the safe with just two big round holes of coins size?

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

The transportation department had found nothing for the time being, but surveillance video had not found any abnormal personnel. In Wanbo City, there were mainly building materials companies, and there was not even a ghost shadow at three in the morning. The police visited everyone inside but did not obtain a valuable sighting report.

There was no gain in intelligence. The local jailbreakers and informants all shook their heads and said this group is too professional. They were not from the same world and couldn't mix with them.

The net police had gained the most. They found the reason why the alarm and internal monitoring failed. The external connection line was cut, and the suspects also used a laser to irradiate the camera to prevent video backup in the factory.

If thread cutting was unconsidered a technique, then what happened in the remote monitoring room in the urban area given all the police officers an ideological education class. The remote monitoring room of the factory was hacked as early as a week ago.

The suspects could not only observe everything that happened in the factory at will but also let the monitor put yesterday's screen playback on the night of the theft. No theft occurred yesterday, and they replayed the picture as usual.

The suspects could watch the factory monitoring at will, and naturally, they had all the layouts in the factory and the location of the monitoring. It is possible it was not an acquaintance who committed the crime, which suddenly complicated the whole case.

"It turns out that watching those spy and thief movies, I also laughed at those directors who were too brainy." A detective spitted out a string of smoke rings bitterly: "The fucking reality is more bizarre than the movie. Look at this, this case is unbroken. . Promise that they will commit the crime again before long.”

"Now all the major Internet news is coming out, we are the headlines, and countless Canadian media are calling to interview us."

"Chief Zhang, what do you think?" Director Zuo of the city bureau reignited a cigarette and coughed: "The provincial government replied. There is no similar case like this case in China. It is basically certain this group is the first one, on this type of theft."

"According to the information obtained at the scene, this group of suspects is professional and heinous. They have brains, knowledge, and the ability to act. The tools used for committing crimes are also things that we have never encountered before."

Zhang Zhitong kept turning the pen in his hand: "I think we should change our thinking. This group is probably not in the traditional sense, those criminals who are lawless and psychologically distorted. It's a group of people who have a strong ability to earn a living in society and certain economic conditions and master the skills related to industrial processing."

In Zhang Zhitong's beautiful eyes, two firm rays of light came out: "A layman, absolutely cannot break through two solid concrete walls in a short time, let alone break a safe with anti-cutting function. And the tools used here are definitely not ordinary."

"I suggest focusing on those machinery factories and investigating the machinery factories in the city."
