Episode 36

In Dongjingxia Village, Tao Weizhi, Yang Wei and Cheng Shufeng were working intensively on the investigation.A simple shack at the entrance of the village caught their attention, with a large stone trough placed next to it.Tao Weizhi quickly recorded the scene on his mobile phone and immediately informed Qin Chuan, who sent Liu Lin, Su Chang and Cao Yang to support.They began to compare the males of the right age in the Upper Village and Higashino Village in Tokyo one by one.

At the same time, Yang Xiaojie, an auxiliary police officer at the Technical Center of the Nanwen Branch of the Zhucheng City Public Security Bureau, finally found key clues in the samples sent from Jiangtai Detention Center through unremitting efforts.The suspect turned out to be Du Kun, deputy director of the Qingjiang City Shantytown Renovation Office, who had just been detained on suspicion of job-related crimes.Guo Jiaqi quickly reported the news to Qin Chuan, who immediately informed Yuan Zhen.Qin Chuan knew that Du Kun would not give in easily and decided to go to Qingjiang in person.Yuan Zhen offered to go with Qin Chuan to cheer him up.

After Gu Wenlong learned the news, he immediately informed Yang Xiong.After hearing this, Yang Xiong was surprised and happy, and hugged Gu Wenlong and cried.The pressure of eighteen years was finally released at this moment.Qin Chuan paid a special visit to Yang Xiaojie, thanked her in person, offered her a bonus of 50,000 yuan, and invited her to dinner.But Yang Xiaojie firmly rejected the bonus, saying that it was the result of the joint efforts of her and her colleagues.She was in a hurry to pick up her daughter, and Qin Chuan no longer forced her.

Yang Xiaojie went to pick up her daughter with joy. This was the first time she arrived on time.Her daughter was smiling from ear to ear, and Yang Xiaojie was also very pleased because she had successfully targeted a criminal with a long history of crimes.On the other side, Yang Xiong, Gu Wenlong and Jin Minghai interrogated Du Kun, while Qin Chuan and Liu Lin watched the entire process via video.Du Kun had an arrogant attitude, refused to plead guilty, and even threatened to sue the interrogators.Qin Chuan had already predicted this and asked Yang Xiong to ignore Du Kun for a few days before looking for other evidence.

Liu Lin rushed to Donglin County urgently to assist in the investigation.Tao Weizhi and Fang Wen learned that the two cases in Qingjiang had been successfully compared, and their pressure doubled.The provincial department sent five experts and test kits, and they stood guard outside the laboratory door and never left.After unremitting efforts by technicians, it was finally discovered that the DNA of four people in Dongjingxia Village matched the samples, and these four people were Wang Hai's family.

Tao Weizhi and others quickly rushed to the Wang family and entered the house on the pretext of checking the electric meter. They confirmed that all four members of the Wang family were present.Later, they took Wang Hai's family to the technical center on the grounds of physical examination.Cao Yang and Su Chang compared the DNA of the four people and finally identified Wang Hai as the suspect.The investigators were so excited that they rushed to tell each other.

Tao Weizhi, Yang Wei and Cheng Shufeng were so excited that they could not speak. Tao Weizhi even broke down and burst into tears.Wang Hai confessed his crime and admitted to killing three girls who were catching tadpoles.He was idle when he accidentally saw the three girls, threatened them with a toy gun, and then raped and killed them one by one.After Wang Hai told his family about the incident, his brother-in-law advised him to go out and escape.He called his father for help, but his father scolded him and asked him to hide in Lingzhou.Wang Hai was arrested as soon as he returned home after hiding for a year.Wang Hai's father cried bitterly and admitted his mistake.The Donglin murder case was finally solved, and Tao Weizhi and others could finally rest in peace.However, Tao Weizhi was exhausted physically and mentally from being overly involved in the case. He felt that he was no longer suitable to be a criminal police officer, so he voluntarily resigned to find his own path.

On the other side, Ou Jiaming continued to interrogate Li Li.Li Li refused to plead guilty and spoke plausibly.The police showed the video evidence of his father and sister. Li Li lost control and shouted to stop playing.When he saw his sister's video, he was even more ashamed and shouted stop.Ou Jiaming took the opportunity to persuade Li Li, and Li Li's psychological defense finally collapsed.He knew he could not escape the punishment of the law, so he confessed his crime of killing three girls.
