There is one word mentioned in both speculative fiction and TV series, and that is perfect crime. The so-called perfect crime is actually a crime that is not detected by everyone or cannot let the prisoner be arrested after being detected. In real life, such behavior basically does not exist, but there was once a case in Japan, which was called by many people as the closest case to the perfect crime, and it will also be a mysterious case recognized in Japan, and the criminal has not been arrested so far.

In fact, before the outbreak of the 300 million yen robbery, the Tama Farmers' Association had already received many threats and threats, and later, according to the tone and tone of the threatening letter left by the criminals, it was finally determined that this intimidation incident was the same as the 300 million yen robbery. In addition, as the manager of a Japanese bank at the time, he also received a threatening letter. When the police learned of this news, they placed 50 police officers at the designated location, but found nothing. Just when everyone thought it was a prank to let their guard down, the criminals easily snatched the three hundred million yen from the eyes of everyone a few days later, and then disappeared directly into the public eye.

The bank set off to a factory to deliver year-end bonuses to the workers, a total of about 300 million yen, which was packed in three different safes. When the 300 million yen cash truck was driving down a road behind Fuchu Prison, it was stopped by a "policeman" riding a motorcycle. When the driver of the cash truck opened the window to inquire, the "policeman" told them directly that a bomb had been planted in the home of the bank governor, and even the car had a very big problem and needed to be checked. Because of the uproar in the bank a few days ago about the president receiving a threatening letter, they directly believed the "policeman's" words.
Shortly after the man climbed into the cash truck, smoke rose from the car, and when the driver heard the policeman shouting that it was going to explode and let everyone flee, everyone ran up in a hurry and watched the "policeman" drive the money truck under everyone's eyes, and when everyone found out that something was wrong, they knew that they were deceived, and quickly chose to call the police.

When the police arrived, no clues were found other than these things left at the scene. Even as the police stepped up their inspections, no trace of the criminals was found. The only good news for the police is that the criminals left 120 crime tools at the scene, whether it is motorcycles, caps, cookie boxes, smoke, magnets, newspapers, in their eyes are strong evidence. But the ideal is beautiful, but the reality is very cruel. When the police spent a lot of manpower and time to investigate the evidence, they found nothing.
Although this was only a 300 million yen robbery, it was still the highest amount of money involved in robbery in Japan based on the price level at that time and the level of objects later. In the seven years after this incident, in order to track down the criminal, 170,000 police forces were dispatched, 110,000 criminal suspects were locked, and finally 900 million yen was spent on it, and the criminal was still not found, far more than the money that was robbed at that time. In 1988, the limitation period for civil litigation had exceeded, and now the criminal has not been caught, and it has directly become an unsolved case.
