Sudden murder >>
24-year-old girl was raped and killed by provincial highway
December 25, 2000, was the unforgettable day of Zhu Yusong, the current head of the Criminal Police Division of the Suqian Public Security Bureau. That was the first serious case that Zhu Yusong, 33, took over as the deputy captain of the Criminal Police Brigade and took over the work for more than a month: at noon that day, the Tanghu Police Station of the Yu County Public Security Bureau in Harajuku received a report saying that it was in Yuantang, Su 304 Line. A body was found in a ditch in the Malou Village section of Huxiang.
At that time, there was no video surveillance in the entire crime scene, and the Su 304 line was the only way between Suqian and Shuyang. There was a large flow of vehicles and people, and it was difficult to detect the case. On the same day, the Suyu County Public Security Bureau immediately set up a task force to mobilize the overall and capable police to assist in case investigation. Based on on-site investigations, forensic identification, and transcripts of the victim’s relatives, the task force believes that the victim Ma Moumou (female, 24 years old, a native of Caoji Township, Suyu) was raped and killed by criminals, and the incident occurred the day before the police received the police. At night, the criminals are most likely locals.
After determining the direction of the investigation, the task force immediately radiated the scope of the investigation from the center site to the surrounding area, focusing on investigations and clues in Yuantanghu Township, Jingtou Township, and Caoji Township, conducting key inspections on former convicts, and posting a reward notice to expand Source of clues. “At that time, the Interpol team had only a few vehicles, and the visits and investigations relied on the feet of the police. It happened to be winter and the weather was extremely cold. Many policemen’s faces, hands, and feet were frozen and cracked, but none of them gave up.” Su Yu Said Wu Liangjing, deputy director of the Public Security Bureau and the investigator of the task force at the time.
"Through three consecutive months of work, the scope of investigation has been expanded to Xinzhuang, Lailong and other towns, and even to Shuyang Yuelai and other places. More than 10,000 people were visited, and more than 1,000 key personnel were investigated. "Wu Liangjing said. However, limited by the investigative conditions and technical means at the time, no valuable clues have been found and no breakthrough has been made in the case.
Perseverance >>
20 years later, the identity of the suspect was finally locked
Although nearly 20 years have passed since the case, the police officers who handled the case have changed batch after batch, some have retired, and some have passed away, but Suqian Public Security has never stopped the work of solving the case.
The police decided to reorganize the case, expand the scope of screening, and focus on all persons with no previous records in the 40-60 age group in the key area. Through the continuous struggle of the investigating police for days, and the screening, screening, and verification of hundreds of millions of data, an important clue gradually emerged.
In mid-July of this year, a piece of good news came: After in-depth application of criminal technology and big data analysis and judgment, combined with the results of preliminary investigation and information comparison, the police of the investigation office believed that Jin Mougang in Caoji Township, Suyu Department was "December 25, 2000." "The possibility of murdering the suspect is extremely high. Although the identity of the suspect is locked, the arrest is not easy. "In the past 20 years, the suspect has been working outside the country, engaged in woodwork, masonry, steel bar work, etc., and rarely has contact with his family. He only knows that he is working at a construction site in Jiangning Science Park, Jiangning District, Nanjing." Suqian City Public Security Bureau Criminal Police Detachment police officer Gao Xing introduced.
At 9:50 am on July 28, with the coordination and cooperation of the Criminal Police Headquarters of the Provincial Public Security Department and the Nanjing Police, the arrested police arrested the suspect Jin Mougang who was working on the construction site. At that time, Jin Mougang did not show the slightest shock. Such a performance made the arresting police conclude that the person must have been caught right.

The suspect knelt on his knees and cried with a headache
After being arrested, Jin did not actively cooperate at first, denying his crimes, and at one time wanted to fight the interrogation by pretending to be crazy. "I have been thinking about how to deal with this day for the past 20 years, but I have never been able to withstand the interrogation of the police handling the case." Jin Mougang said.
In the end, Jin Mougang confessed the fact that Ma was raped and killed 20 years ago in the section of Malou Village, Yuantanghu Township, Su304 Line. On the morning of August 1, Jin Mougang came to the crime scene again wearing handcuffs and shackles.
