On December 9, a naked female corpse was found on the streets of downtown Tancheng. The DNA detected in her body was a perfect match with the DNA of the murderer of the notorious Tancheng serial girl rape and murder case 23 years ago.
The Ministry of Public Security sent Professor Li Zhi, who had presided over the case three times, to Tancheng to guide the crime.
After Li Zhi came to Tancheng, he read the files and found that there were many differences between this case and the serial rape and murder of young girls.
He first put aside his doubts, tracked down the first scene of the crime, and deduced that the murderer used a tricycle to transport the body. There were no tricycles in the city's waste recycling stations. Unexpectedly, due to the regulation of the upstream reservoir, the water level of the Tanjiang River dropped, and the front of the tricycle was exposed in the water under the Tanjiang Bridge.
The police department organized a salvage operation and unexpectedly recovered eleven murder weapons from 23 years ago.
No biological information of the murderer was found on the murder weapon or the tricycle.
The case seems to be at a dead end when an insurance company investigator comes to the police station to learn about the murder.
It turned out that the deceased had purchased accident insurance worth RMB 2 million before his death.
Another witness confirmed that the deceased's husband used to ride a tricycle to collect scrap.
The salvaged tricycle was exactly the same as the photo in the car revelation posted by the deceased.
A serial killer returns to commit crimes or kills his wife and cheats on her bail?
After the husband of the deceased was called to the police station for interrogation, a fire broke out in his home that night and he was burned alive.
Firefighters discovered that the fire was arson and accidentally discovered a secret camera at the scene.
The secretly filmed video was partially recovered, revealing the truth behind the serial rape and murder of a young girl.
It turns out that the deceased and her husband conspired to commit a series of crimes more than 20 years ago, and the victim turned out to be the perpetrator...
Purpose: The pain of victims' families should not be ignored
