The male body was found in Qingpu pond in Shanghai. Why did the truth come out after 18?

There is no perfect crime. 18 years ago, a man's body was found in Qingpu pond in Shanghai. At that time, I only knew the general appearance of the two murderers. Now, 18 years later, through high-tech means, two criminals finally fell into the law. So why the 18-year interval?

The editor thinks so: First of all, the incident occurred in 2002, when all kinds of monitoring facilities were not perfect, the level of science and technology was not developed enough, and the pictures taken by monitoring facilities were not clear, so it was difficult to determine their appearance; Secondly, the communication facilities were underdeveloped at that time, and witnesses and related personnel were not necessarily connected; Thirdly, the network system was underdeveloped at that time, and it was difficult to determine their whereabouts through online and consumption records; Finally, at that time, the management in many places was not strict, which made it easy for criminals to live among ordinary people. As a result, two criminals hid for nearly 18 years.

Later, with the progress of science and technology, the application of the Eye of the Sky system and the popularity of big data, the police quickly locked in two suspects and tracked them. Everything pays off. 18 years later, the two murderers finally fell into the French Open and were very popular.

The two fugitives have been hiding for so many years, which proves that their hiding methods are clever, but even if they are clever, they can't escape from the public, and the law can't escape the fate of being caught. Similarly, the serial silver murderer who committed the heinous crime in 1988 was also arrested on 20 17. It can be seen that in recent years, China has not only actively explored and studied in science and technology, but also made great efforts in politics and the rule of law, making the method of judging cases keep pace with the times, and the most commendable thing is that the public security is willing to keep pursuing the case and really explore it.

Facts have proved that there is no perfect crime in the world. As long as a crime is committed, there will be clues left by criminal means. Especially in this era of advanced technology, as long as they have identity, they will leave traces in society, so those fugitives will fall into the law. It's only a matter of time.
