After the murder of To Kwa Wan that year, the police quickly targeted the suspect on her boyfriend Wu Zhijia by visiting the interpersonal relationship of the deceased Luo Jingjing, including the herbal tea shop where he worked was also included in the first scene of the crime. Not long after the court's decision was issued, the herbal tea shop went out of business. Situ Liang bought the herbal tea shop and re-simulated the layout. Without the help of new technology, the only way to preserve clues is to take this approach.
As for why the police identified Wu Zhijia as the murderer, it was mainly due to the testimony of Luo Jingjing's classmates and the conjecture of Wu Zhijia's motive for murder based on environmental evidence. According to the information provided by her classmates, Luo Jingjing went to Wu Zhijia's herbal tea shop on the day of the crime, and made an agreement with her friends to exchange cartoons at Matouwei Village at ten o'clock at night.
However, during this period, Wu Zhijia was unhappy the whole time, and it was suspected that he had encountered some difficult money problems. Luo Jingjing went home after leaving the herbal tea shop, and went out alone until 8 pm. Witnesses confirmed that she appeared on the stairs of the building near the herbal tea. On the other hand, the friend of the deceased described that he arrived at Ma Tauwei Village on time at ten o'clock, but he did not wait for Luo Jingjing to appear. He also knew that she had a habit of not being punctual and breaking appointments. A huge cardboard box was found nearby, and inside it was Luo Jingjing's body.
Although the cardboard box and the corpse have long been defined as contaminated, considering that the evidence collected was too small and based on the testimony of everyone, the deceased Luo Jingjing lost contact after 8 o'clock the night before, so the police immediately blocked the herbal tea shop, guessing Wu Zhijia There is a money dispute, and he accidentally kills his girlfriend Luo Jingjing.
In order to restore the scene even more, Situ Liang took out a cardboard box containing Wu Zhijia's fingerprints, herbal tea herbs and clothing fibers. However, these items are all environmental evidence and cannot be 100% sure of the identity of the murderer. In fact, the public was very concerned about this case back then. Due to the pressure to solve the case as soon as possible, the police directly accepted the evidence that had not been confirmed and was unfavorable to Wu Zhijia, thus ignoring that Wu Zhijia had received a hundred-yuan note with the number "A333888". How could they know the case? On the day of issuance, the banknotes disappeared out of thin air.
Yu Xingbai felt that banknotes were the key to attracting the murderer, but unfortunately the police did not believe it at all and did not actively search for the whereabouts of the banknotes. It has been forty-two years now, and Situ Liang is eager to find out the truth. Yu Xingbai found that he had found a third party's blood on the broom of the herbal tea shop. He immediately contacted the forensic department to conduct a blood test. The report concluded that this person was most likely from Southeast Asia. membership, and the habit of taking drugs.
Situ Liang took Yu Xingbai to find Wu Zhijia, and found that he was being entangled by media reporters. Thanks to his good brother Shen Dahui, who came forward to relieve the siege, not only did he not dislike his previous imprisonment, he even introduced him to work. Wu Zhijia thanked Shen Dahui for being a friend. While the two were talking, Situ Liang and Yu Xingbai came over and took out a virtual portrait of a third party to ask him about the situation. But when Wu Zhijia saw the portrait for the first time, his expression changed suddenly, saying that he no longer wanted to clear his grievances, but hoped to live a normal life.
After get off work that day, Wu Zhijia hid in a corner and silently watched a mother and daughter, until the girl found out that he was frightened and ran away. The girl Mo Jingen came over and found that Wu Zhijia's calf was injured. She kindly gave him a Band-Aid. Wu Zhijia was in a complicated mood and gave him a hand rope woven from cattails.
After Situ Liang visited and investigated, they finally found that the person on the portrait was a snakehead named Lin Fa, whose main job was to help people smuggle. Situ Liang and Yu Xingbai came to the abandoned winery that Lin Fa frequented, and sure enough, they detected something abnormal in the cement.
Fan Peiqing inspected the body. In addition to the fatal abdominal wound and tooth marks on the calf, he also found clocks, papyrus bracelets, and fragments of old newspapers. DNA confirmed that the deceased was Lin Fa. Jing Haoran felt that there must be an inseparable connection between Lin Fa and Wu Zhijia. Perhaps the two cases could be investigated together. He went to Wu Zhijia to understand the situation and saw Mo Jingen.Mom is warning Wu Zhijia to stay away from her daughter.
The two went to the police station for interrogation. Jing Haoran noticed the bracelet Wu Zhijia gave to Mo Jingen, but Wu Zhijia denied that he knew Lin Fa. Huo Baoying dug out Jinzao Daily on October 11, 1980 through fragments of old newspapers. There was also this newspaper in the cardboard box that hid Luo Jingjing's body, but the horse racing edition was missing, which meant that the newspapers on Lin Fa and Luo Jingjing belonged to the same.
Although the forensic doctor and the forensic department could not confirm Jing Haoran's guess, they were basically able to determine that Lin Fa died at 4 pm. Jing Haoran believed that even if Wu Zhijia was not the murderer, he would definitely participate in the cement burial. Fan Peiqing took out the dental test report again, emphasizing that the person who bit Lin Fa's calf was most likely an eight- to twelve-year-old child.
Huo Baoying came to the herbal tea shop alone to investigate the case. Seeing that she was so interested in Yu Xingbai, Situ Liang couldn't help but recall that he fell in love with his girlfriend Liu Qing at first. Yu Xingbai was waiting for Situ Liang and Huo Baoying outside the herbal tea shop. The three asked Shen Dahui of Xingqi Property Company about the situation and asked him if he had seen the handwriting on the newspaper.
Shen Dahui said that he couldn't remember it at all. Afterwards, he threw the copy left by Situ Liang and others into the trash can. It happened that Wu Zhijia saw this piece of paper in the trash can. Mo Jingen's mother was dismantled selling fake bird's nests, and she actually pushed her daughter out as a shield. Wu Zhijia appeared in time to drive away the women who abused Mo Jingen, and also offered to buy her ice cream to soothe her emotions.
Mo Jingen is very grateful to the uncle in front of him. I believe he will never be a murderer. In fact, Wu Zhijia already knows the identity of the murderer, but he is reluctant to confess because of his friend's love, not to mention that even if the case is overturned, time cannot be traced back. At this time, what Mo Jingen said inadvertently reminded Wu Zhijia, and took the initiative to provide Situ Liang and Yu Xingbai with photos from middle school, and determined that Shen Dahui was the murderer. That night, Situ Liang received a call from Huo Baoying and learned that she had contacted the insider who collected the missing banknotes.
