Tools for committing crimes were the most important material evidence in criminal cases, and it was also one of the means to identify suspects.
As soon as the jewelry theft case came out, the whole Zhongyun City was in a sensation, and all the police forces were mobilized.
The faster the case was solved, the more the administrative efficiency of Zhongyun City could be extracted, and the rest of the thieves could be severely deterred.
Look, even the Daimeng Jewelry theft case, an unheard of high-tech crime, has been solved. You idiots who only know how to wear helmets with hammers, still expect to challenge the ability of the Zhongyun police?
If the case dragged on for three or five months, not only the city's image would be damaged, but the entire Zhongyun City's shops that sell valuable goods would be frightened.
With Wanbo City as the center, all the surveillance videos within a few kilometers were retrieved.
All forces were mobilized to carefully examine the videos.
This group of daring thieves could accurately find out the warehouse and paralyze all the security devices. They must have explored the place in advance, or there was the possibility of an acquaintance committing the crime.
If they had explored the place in advance, the previous video would have captured clues.
The collapsed hole was one meter wide and one meter high. Zhang Zhitong bent down and got into the hole.
The scene inside was difficult to be compared with the previous crime scene where ten bulls had taken turns to charge.
Because except for the warehouse where the jewelry was stored, there was no sign of any other room being turned over.
The Daimeng Jewelry Factory was an independent two-story factory building. Before Daimeng Jewelry moved in, it had been carefully decorated.
The door was a Class A electronic anti-theft door. From the entrance to each storage room, it was all anti-theft doors. All the windows were inlaid with strong anti-theft nets. When the workers got off work in the evening, the vibration alarm would be turned on.
In order to prevent the security guards from stealing or being attacked by thieves. The boss of Daimeng Jewelry put the monitoring room in the company in the city, which meant that there was no one in the factory at night.
Before getting off work, the boss of Daimeng Jewelry would personally check the work of the jewelry warehouse. The picture of the remote monitoring room last night was also normal. There was not even a shadow of a mouse.
This defense had actually reached the extreme of a jewelry company of his size.
But he didn't expect that this group of thieves would do more extreme than him. After breaking through the gap from the outer wall closest to the warehouse. This group of thieves didn't do any unnecessary probing, and they didn't do any unprofessional searching.
They went straight to the jewelry storage room and used a method that the police officers could not understand for the time being. They opened a big hole in the side of the storage room and looted 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, open as a door to the safety net, it showed how ridiculous the safety precautions were.
On the front of each safe, there were two round holes the size of coins. Around the round holes, there were traces of melting.
It was these round holes that caused the five huge safes to be completely lost.
A policewoman stood up and whispered to Zhang Zhitong, "Zhang Ke, I have a bad feeling about this. No outsider's fingerprints were collected at the scene. All of them belonged to the boss of the jewelry company. "
"There are no footprints either. The suspect probably put something on his shoes beforehand."
"Since they were so well-prepared, they must have made careful arrangements on the route of retreat and disposal of the stolen goods. If we want to catch them, we can only rely on luck. "
Zhang Zhitong didn't speak. She squatted down with her trousers and carefully examined the two round holes in the safe.
About half a year ago, the warehouse door of the Silver Palace Club left a very deep impression on her. Whether it was flame cutting or plasma cutting, it couldn't destroy the anti-riot door at the entrance.
These safes in front of her were traditional safes with mechanical password discs and key locks. According to the information fed back by the manufacturer, their safes also had the ability to resist flame cutting.
Plasma cutting could break it, but a plasma cutting equipment, which was larger than a safe, could not be moved in from the hole.
Also, how did he open the safe with only two holes the size of coins?
In the afternoon, Zhang Zhitong returned to the bureau and other departments to check the clues she had at present.
The traffic department found nothing for the time being, and the surveillance video did not find any abnormal people. Wanbo City was mainly a construction material company. At three o 'clock in the morning, there was not even a ghost shadow. The police interviewed everyone inside, but did not obtain a valuable eyewitness report.
There was no gain in intelligence. The local jailers and informants shook their heads and said that this group of people was too professional. They were not in the same world as him and could not mix together.
The net police had the biggest gain. They found the reason why the alarm and internal monitoring failed.
The external connection was cut off, and the suspect also irradiated the camera with a laser to prevent video backups in the factory.
If cutting the wires was not considered a skill, then what happened in the remote monitoring room in the city gave all the police officers an ideological education lesson.
The remote monitoring room of the factory was invaded as early as a week ago.
The suspect could not only observe everything that happened in the factory at will, but also let the monitor play back yesterday's picture on the night of the theft.
There was no theft yesterday, and everything was as usual in the playback picture.
The suspect could watch the factory surveillance at will, and naturally mastered all the layout in the factory and the location of the surveillance. Then it may not be an acquaintance who committed the crime, which suddenly made the whole case complicated.
"It turned out to be watching those spy and thief movies. I also laughed at those directors for being too imaginative." A criminal police officer spat out a string of smoke rings: "Damn, the reality is more bizarre than the movie. Look at this, this case is not solved. It won't be long before they commit the crime again. "
"Now the news on the major Internet has come out. We are the headlines. Countless media outlets have called to interview us."
"Little Zhang, what do you think?" Director Zuo of the city bureau re-lit a cigarette and coughed: "The provincial department has replied that there is no similar case in the country at present. It is basically certain that this group of people is committing the crime for the first time."
"According to the information obtained at the scene, the professional means of this group of suspects are outrageous. They have brains, knowledge, and the ability to act. The tools used to commit the crime are also things we have never touched. "
Zhang Zhitong kept turning the pen in her hand: "I think we should change our thinking."
"This group of people is probably not in the traditional sense, those lawless and psychologically twisted gangsters."
"It's a group of people who have a strong ability to make a living in society, and certain economic conditions, and master skills related to industry."
In Zhang Zhitong's beautiful eyes, two firm rays of light shot out: "A layman absolutely can't break through two solid concrete walls in a short time, and it's even more impossible to break through a safe with an anti-cutting function."
"And the tools used in it are definitely not ordinary."
