After many years, the serial killer of the Haizhou case reappeared and brutally killed a young woman with the same method. As the poison report came out, it was confirmed that there were muscle relaxants and anesthetics in the victim's blood. Leng Xiaobing was worried that Xia Mu would act impulsively, and immediately called Xia Mu back. However, the other party did not answer the call for a long time, so he asked Chen Han and Liu Yu to find him at home.
As everyone knows, Xia Mu came downstairs at Shen's house at this time and happened to see Shen Yu driving away, so he chased after him. During this period, Xia Mu found a man in Shen Yu's car. Because only the back cannot see the front, he suspected Shen Haiyang for the time being.
On the other hand, Leng Xiaobing asked the forensic doctor Lao Gu about the situation of the deceased. He had doubts about the modus operandi. In the past, the murderer would take the alarm clock away, but this time he chose to stay. Old Gu found a memory card in the throat of the deceased, and identified it as if it was inserted after death, much like deliberately leading a clue.
Xia Mu was intercepted by Chen Han and Liu Yu while pursuing Shen Yu alone. When the police were dispatched to implement the containment, it was unexpected that Shen Yu was in a car accident and was unconscious on the spot. The so-called "Shen Haiyang" was actually He Weiguang pretending to be. Although Shen Yu was bandaged and his injuries were not serious, He Weiguang's situation was not optimistic. Even if he saved his life, he became a vegetable.
Shen Yu lay on the hospital bed and pretended to sleep, and didn't open his eyes until Leng Xiaobing left the ward. When Dr. Wu saw Leng Xiaobing, he suddenly thought of He Weiguang's previous suspicious behavior, and simply provided him with a video of the murder described by He Weiguang when he came to Shen Yu for treatment.
When Xia Mu learned that the man in the car was He Weiguang, she was surprised. Leng Xiaobing found some tin toys in Shen Yu's car. They were all lost in the homes of the victims of the Haizhou case. There were also He Weiguang's fingerprints on them. All sorts of clues pointed to him as the murderer. Xia Mu blamed Leng Xiaobing for letting Chen Han stop him, otherwise the car accident would not happen, but Leng Xiaobing reprimanded Xia Mu for acting without authorization and had already forgotten the three chapters of the contract because his impulse had been used by others and became a pawn on the chessboard. .
The criminal police team analyzed the case of Rongcheng Jiayuan, Leng Xiaobing pointed out that the suspicious point was the alarm clock. He had seen it at the scene 17 years ago. Every time the murderer would take it away, he stayed at the scene this time. The Ministry of Technology extracted six sets of DNA inside the alarm clock and found Ning Li, the victim of this case, and five victims of the Haizhou case.
Now all the evidence points to He Weiguang, and Leng Xiaobing suspects that someone framed him. Xia Mu confessed to Leng Xiaobing about surveillance, including fainting at home and being taken to the hospital before returning home to find the glue in the keyhole. Leng Xiaobing called on the surveillance of the hospital and found that on the day of the Rongcheng Homeland case, Shen Yu left work before 8 o'clock and had time to commit the crime. Even during another period of surveillance, he saw that Shen Yu had been to Ning Li's performance.
Leng Xiaobing and Xia Mu both believed that Shen Yu was extremely suspicious, and decided to investigate He Weiguang's house. Sure enough, they found many clues, speculating that He Weiguang had entered a nightmare alive under Shen Yu's deliberate arrangement. Before that, Shen Yu asked an intermediary to rent a house downstairs in He Weiguang, with the same layout and exactly the same layout. He disguised 803 as the scene of the crime in advance, making He Weiguang mistakenly believe that he was a murderer and was greatly stimulated and dizzy. It's actually 903 when I wake up again.
Given that Shen Yu's strength was not enough to move an adult man from the eighth floor to the ninth floor, Xia Mu decided that Shen Haiyang was nearby. As long as one of the clues was grasped, the truth could be found. After the incident, Gao Peng interrogated Shen Yu and confirmed that Shen Yu did go to Ning Li's performance, but she didn't mention a word about her father's disappearance.
Xia Mu learned through Chen Han that the evidence chain held by the police was complete, and he could be convicted even without He Weiguang’s confession. What Xia Mu felt even more uncomfortable was that she could not convict Shen Yu because of insufficient evidence. Leng Xiaobing clarified what happened back to Gao Peng and speculated that Shen Haiyang might be the murderer of the Haizhou case, because the time of Shen Haiyang’s disappearance coincided with the murder of Xia Jinlan. All traces of a missing person’s life were erased. This is very important. suspicious.
However, Gao Peng dismissed Leng Xiaobing's judgment on the grounds of insufficient evidence. Leng Xiaobing applied to go to the site of Rongcheng's homeland again, and by the way, he compared Shen Yu's DNA in the DNA database to find out if there was a match. It didn't take long for Shen Yu's NDA matching result to be released. What shocked everyone was that Shen Haiyang, who had been missing for many years, had long since died.
