Shanxi Changzi police cracked the backlog of murder cases from 15 years ago. Why are there so many backlogged cases?

I personally think that the reason why there are so many backlogged cases is because of three reasons: First, the criminal investigation technology is backward and not as perfect as it is now; second, because the transportation is not as convenient as it is now; third, because of the lack of experience in handling cases, many cases Incomplete clue analysis.

Whether we listen to criminal investigation novels, watch criminal investigation TV series, or read real-life news reports, we can always learn about the detection of many backlogged cases that have not been solved for many years. Every time we hear such news, we see It's really satisfying to see criminals get the ending they deserve.

Recently, Jin, a criminal suspect in Changzi County, Changzhi, Shanxi, who murdered a female taxi driver surnamed Zhang and then absconded and changed his name and continued to live there for 15 years, was captured. After learning that the murderer had been caught, the family of the female taxi driver surnamed Zhang was filled with emotion and sent a banner with the words "Detect murder case, demonstrate police power, people's police, and a mountain of kindness" to the hands of the eldest son's police officer handling the case.

We are very pleased to see this situation, but at the same time we have various doubts. Why do many backlogged cases take many years to be solved? According to my analysis, this is mainly related to three reasons. Let’s explain them one by one below.

1. The backwardness of criminal investigation technology has led to the backlog of cases

Nowadays we often hear about high-tech information systems for solving crimes such as DNA gene banks and fingerprint systems, but in that era Even if it existed, it would not be as perfect as it is now. What's more, Internet technology was not so popular at that time, and many criminal cases could not provide comprehensive technical support to criminal police. Therefore, many cases were due to backward criminal investigation techniques, which led to backlogs that could not be solved.

2. The inconvenience of transportation leads to the backlog of cases

We all know that the traffic conditions are very convenient now, but many backlogged cases were caused by the inconvenience of transportation that delayed the handling of cases. The cases became backlogged. At that time, many localities handling cases might have only one police car per county. When searching for criminal evidence, police officers sometimes rode bicycles and went door to door to inquire. Since the residents of each household lived far apart, it took a long time to collect evidence. period of time, which also resulted in many key clues being destroyed by deliberate criminal suspects.

3. Insufficient experience in handling cases resulted in many cases becoming backlogged

You must know that at that time, there were no public security universities or forensic schools that specialized in training criminal investigation talents, and the investigators relied on their The older generation of criminal police passed on their knowledge and used their own analysis of the environmental evidence at the scene to solve the case, which resulted in incomplete clue analysis and affected the detection of the case.

IV. Conclusion

Based on the above three points, many cases have not been solved for many years and have become backlogs. However, with the advancement of criminal investigation technology, more and more backlogs have been solved, so It completely verifies the truth of the saying: "The legal network is wide open, but it is sparse and not omitted."
