Who can help me find a case study of selling safes in America ~ ~ Thanks again ~ ~
Analysis:
Last February, a major breakthrough was made in the theft of extra-large diamonds in Antwerp.
According to *** (ABC), a serious diamond theft occurred in Antwerp, Belgium, the diamond cutting capital of the world, on the night of February 16, 2003: In this case, 123 in the diamond center 160 safes became empty overnight! The direct loss caused by this theft is estimated to exceed $654.38 billion (equivalent to more than 900 million yuan). What puzzles the police is that this diamond center has world-class security measures. How did criminals steal so many diamonds at once without knowing it? After nearly a year's investigation, a major breakthrough was finally made in the detection of this sensational case.
The process is comparable to Hollywood blockbusters.
This is definitely a seamless theft: On the night of February 16, 2003, Jiang Yang thieves broke through several layers of the highest safety net in the world and stole diamonds worth as much as 1 100 million dollars from the vault of the Belgian Diamond Center in Antwerp! After committing the crime, the Jiang Yang thieves drove away from the crime scene calmly, with security patrols, armed guards and police stations beside them. This is a serious crime committed under the nose of the police station, ignoring the battle-hardened detectives inside. This theft gives people the feeling that they are watching movies like Crossing the Sea and Stealing the Sky.
There is a jeweler of unknown origin.
A reinforced concrete building in the center of Antwerp diamond district is a world-famous diamond center. Hundreds of jewelers do business in it, and many of them put their precious jewels in the vaults on the first and second floors. The security measures in this three-block jewelry district are very strict: 24-hour patrol, and there are many cameras monitoring everything here.
As there was no sign of breaking into houses, the police soon thought that the theft was committed by insiders. But who can organize such a large-scale theft? The police quickly identified a tenant of the diamond center as a suspect. This man is also a jeweler named Leirad NotteBotule. He used to do jewelry business in Turin, Italy. But the police in Turin know his criminal history. More than 20 years ago, he had a long record of petty theft and several criminal records of burglary. The local police suspected that Nott Bertule was a member of the Turin Gang. The "Turin Gang" is composed of criminals with legitimate jobs as the cover. They cooperate with each other to carry out more professional criminal activities.
Before the theft, Nott Botule came from Italy to work in the diamond center in Antwerp, Belgium only one day a month. But investigators found that he stayed in the diamond center every day in the week before the theft.
The method of investigating the crime is surprising.
According to the analysis of the police, what happened should be like this: at 7 o'clock on Friday night, the door of the diamond center was locked, and Nott Butler was the last person to leave that night.
The next night, at about midnight on Saturday, at least three people took the elevator to the vault. These people or their associates destroyed the security monitors used to protect the area in advance. Spray silicone on the sensor and attach the light wave monitor with adhesive tape. Therefore, thieves can walk freely at the crime scene. They came to a door next to the vault, broke in and found a small metal box. They know that there is a key to the vault in this box.
The police don't know how these thieves know the password to enter the vault, but even if they enter the correct password and insert the stolen key, they still have to face a more insurmountable obstacle: the alarm on the vault door.
Usually, when this two-foot thick metal door is opened, two attractive magnets will be pulled apart, which will trigger an alarm to the police station. But the thief cut the bolt connecting the two magnets. Then they tied the two magnets together, moved them aside, and finally opened the door. The alarm didn't go off because the magnet was still touching.
The thief thus entered the vault, but the diamonds were still kept in the safe. They assembled a special tool with some common mechanical parts and used it to unlock each safe.
Clues, Woods, bags, pouches, holes
The thieves in Jiangyang threw away some garbage bags when they were distributing stolen goods in the Woods. But the owner of this grove accidentally picked up these garbage bags. Soon he found that these bags contained a pair of gloves, several file bags, some money and diamond bags. He was suspicious of this and reported it to the police. But the breakthrough in this case was found in one of the bags.
The police found the following things in this small bag: a receipt from a gourmet shop, a half-eaten salami sandwich, and a diamond center receiving place that was torn to pieces.
Invoice. The police recovered the invoice and found that it was a document involving Nott Bertoller. There is also a receipt from the toll station of the expressway, which runs through the Alps and leads from Italy to Antwerp. The receipt was issued shortly before the theft. The police also found several mobile phone numbers related to Nott Botule. There is also a receipt from the hardware store, which lists the items that the thieves threw into the vault.
In addition, the police found that the safe in Nott Bertule's vault was not stolen. This is one of the few safe boxes that has not been stolen.
The case of breaking through the "stealing the sky" is about to come out.
On the first Friday afternoon after the case, Nott Bottler casually came to the Diamond Center in Antwerp. The security guard in the building informed the police. The police couldn't find anything related to the case on Nott Botule. He told the police his home address in Antwerp. The police rushed there and found his wife and friends moving things to the car, ready to leave here. Police officer Rob Decatur said, "In a minute, they will leave! We are very lucky again! "
Although Nott Botule's apartment was almost empty, the police found a lot of evidence from it. They found a small diamond, an Italian sausage and a bottle of wine on the carpet, which is consistent with the receipt they found in the Woods.
Nott Bertule was arrested and detained in Antwerp prison, and is currently awaiting trial.
