Considering Mu Mu's personal safety, especially the extremely dangerous situation now, Ling Ran asked his ex-husband Song Yuan to pick up Mu Mu before making a decision after the storm subsided. Although Zuo Jiang had been released on bail by the lawyer, Chen Hu and Geng Ning always followed behind, witnessing him entering an adult goods store and carrying the supplies home in a magnificent manner.
For a while at the beginning, Zuo Jiang didn't have any suspicious things. When Chen Hu was squatting downstairs, he received a message from his daughter, so that he patronized the reply and didn't notice the abnormality. After he was reminded by Geng Ning, he picked up the binoculars and looked at the window, and found that Zuo Jiang was holding the inflatable doll and waving gestures in front of the window, casting provocative gazes.
Qin Xinyi re-verified Zuo Jiang's identity and confirmed that the other party had indeed moved to Bincheng from Lianyun City eight years ago, when he was only 19 years old and his parents had long since passed away. Later, Qin Xinyi investigated the household registration department of Lianyun City again, and unexpectedly discovered that there was no entry and exit record of Zuojiang at that time, which means that Zuojiang now forged household registration information.
Ling Ran asked Qin Xinyi to contact the Lianyun City Public Security Bureau, and at the same time submit Zuo Jiang's photo and fingerprints, aged between 25 and 35. Unexpectedly, Xue Tao killed two people one after another at Zuo Jiang's sign that night, and threw their bodies by the river in the suburbs. Judging from the scene and time of the forensic doctor, the modus operandi is similar to the previous several murder cases, and it can basically be concluded that the same person did it.
Excluding the possibility that the deceased was a vendetta or a love killing, Ling Ran correlated the clues he had at present and deduced that Zuo Jiang and the two killers belonged to a gang attack. The specific internal relationship is unknown. Ling Ran and Qin Xinyi investigated Zuo Jiang’s true identity and found that he used the name Zhao Donghui and was born into a wealthy business man’s family. After years of violent beatings, especially after witnessing the death of his mother tortured by his father, he was finally manslaughter and imprisoned. Sentenced for six years.
Because of this, Ling Ran took the initiative to explain the situation to Huo Bureau and applied to Qingyang Township Prison for investigation. Because in recent days, Ling Ran repeatedly recalled that diary, which was full of his father’s analysis and inferences about the case. Although many details were blurred, he vaguely remembered that the murderer should have been in prison before killing, and had a strong anti-reconnaissance. ability. Therefore, Ling Ran believed that after his father died, the murderer could suddenly disappear, and he could hide for twelve years without being discovered by the police. There was no other possibility other than the prison. Perhaps it was also the place where he and Zuo Jiang met.
Chen Hu and Geng Ning were responsible for monitoring Zuojiang as usual. Just as he was bored, they suddenly received a call from Lin Jing and learned that she was about to take her daughter abroad. At the critical moment, Chen Hu finally came to the airport to see him off. Chenchen had already sensed his identity, and was extremely reluctant to leave. Originally, Chen Hu, according to his daughter's request, specially went to buy a piece of fried chicken nuggets nearby, but when he turned around, Lin Jing and her current husband dragged Chenchen on the plane and left.
From that day on, Chen Hu was quite depressed. On the other hand, Ling Ran found a lot of information in Qingyang Township Prison, including the brawny Shen Peng, Zhao Donghui who changed his name to Zuojiang, and Xue Tao who was attempted to rape. Although the three have different experiences, they all have different degrees of psychological distortion. Ling Ran guessed that Zuo Jiang was able to pass the polygraph technical appraisal because he did not understand the homicide process in the previous cases, which is enough to prove that they have different division of labor. Zuo Jiang Jiang was responsible for planning, and Shen Peng arrested people and handed them over to Xue Tao.
At the same time, Chen Hu disappeared for no reason, and Ling Ran called for surveillance and saw that he was kidnapped by Xue Tao. Geng Ning and others immediately arrested Zuojiang and interrogated them overnight, but unfortunately there was no progress. It was a matter of life and safety, and everyone was extremely patient. Zuo Jiang was very satisfied when he saw it. He simply took out a video containing Chen Hu's coma. The murderer asked the police to find the location within the specified time, otherwise it would not be overdue.
