From 1988 to 2002, ten brutal murders occurred in Baiyin City in succession. Women living alone were brutally murdered. The murderer was skillful and secretive, but he has never been caught. The case shocked the country and became a bloody mist shrouding the entire city.
Young detective Li Jianguo has been deeply involved in the case since the first case, growing from a young police officer to the core of the task force. In an era when criminal investigation technology was backward, he and his master, Lao Zhang, and others relied on visits and investigations, groping through massive clues, but repeatedly reaching deadlocks. The tears of the victim's family members, social doubts, and family alienation have never shaken his vow to "solve this case."
Over the past fourteen years, the murderer continued to commit crimes and suddenly went dormant. The police approached him several times but missed him. Li Jianguo spent countless late nights scrutinizing the files, catching subtle anomalies from the traces. With the addition of the new generation of forensic doctor Chen Xi and technician Zhao Lei, DNA technology has gradually become more popular, and the detection work has shifted from "human sea tactics" to "technology to chase the murderer."
In 2016, through genetic comparison and kinship investigation, the police finally identified the murderer Gao Chengyong who was hiding in the street. A back-and-forth pursuit of a murderer that spanned nearly thirty years condensed into the collective memory of a generation of criminal investigators at the moment the truth emerged.
This book is based on real cases and has 500 chapters. It not only restores a tortuous and difficult investigation process, but also profoundly depicts the persistence of criminal investigators, the imprint of the times behind technological progress, and the profound theme that justice will never be absent in the process of the rule of law. This is a criminal investigation epic about time, obsession and redemption.
