Thirteen Years of Dust 尘封十三载 Episode 12

The name of the deceased was Tao Yufen, who was the first relocated household in the east of the old city. Tao Yufen is not single, he has a spouse named Chi Yong, Wei Zhengrong took Lu Xingzhi to find Chi Yong to understand the situation. Chi Yong was working at the playground, so he was not surprised that Tao Yufen didn't come home last night, because Tao Yufen said that she was going to find her sisters, maybe she stayed at someone else's house last night. Wei Zhengrong told Chi Yong about Tao Yufen's death, and Chi Yong burst into tears immediately, and the two brought Chi Yong back to the bureau for investigation. Lu Xingzhi and Wei Zhengrong had a disagreement. Lu Xingzhi believed that Chi Yong might be the murderer of Tao Yufen, but not the murderer of Liu Meng and Du Mei at the same time. Wei Zhengrong only looked at the evidence. If it was a copycat killing, how did the murderer know the never-before-disclosed detail of the pencil.

Master Lu, the forensic doctor, told Dui Huo, Lu Xingzhi and Wei Zhengrong about the death of the deceased. Unlike the previous two deceased, Tao Yufen had a much deeper wound on her head. Lao Zhu asked Tao Yufen's sisters and came back to tell Wei Zhengrong the situation. Lu Xingzhi always believed that this did not meet the serial killer's motive for killing. Then the master and apprentice went to the playground to inquire about the management, and learned that Chi Yong had indeed asked for leave last night for half an hour. Lu Xingzhi practiced himself, riding a bicycle back and forth between the place where the body was dumped and the playground. Wei Zhengrong calculated the time, but the whole process took more than half an hour. Lu Xingzhi proposed a possibility. He killed Tao Yufen first, and then hid the body in a certain place, and then dealt with it after get off work.

Lu Xingzhi and Wei Zhengrong split up to find a possible hiding place. In the abandoned haunted house, both master and apprentice found a woman's coat with bloodstains at the same time. Back to the police station to interrogate Chi Yong, Chi Yong admitted that he killed Tao Yufen, but denied that Liu Meng and Du Mei were also murdered. Wei Zhengrong questioned him why he would put a pencil on the scene, Chi Yong insisted that he heard about it on the street. Before Lu Xingzhi finished speaking, Wei Zhengrong stepped on him, signaling him to stop. At Chi Yong's home, a pair of shoes in size 41 was found, and the shoes were compared to Master Lu, who said that the possibility of being a pair of shoes could not be ruled out. Wei Zhengrong continued to interrogate Chi Yong. This time Chi Yong was obviously flustered, but he said that everyone in the playground had such a pair of shoes.

Wang Li from the amusement park told Wei Zhengrong and Lu Xingzhi that Chi Yong had strangled her and said she was the third one. For fear of being discovered, Chi Yong still did not kill Wang Li, but took her underwear and hid it. According to Wang Li's identification, Lu Xingzhi found the underwear. Facing the interrogation again, Chi Yong admitted that both Liu Meng and Du Mei committed suicide, and he was right about the general details. The team thought that the case had been solved, so Team Huo proposed to have a good celebration. Lu Xingzhi stood up and said that there were still doubts about the case, but Wei Zhengrong refuted his views one by one. The large conference room was finally vacated, but Lu Xingzhi felt extremely disappointed, but he still did not give up looking for evidence to prove that Chi Yong was not a serial murderer.

Lu Xingzhi returned to the scene of the crime, and Wei Zhengrong also checked the files and photos again. When Lu Xingzhi came back, he looked at the photos with Wei Zhengrong and found an important breakthrough. Among the crowd at the scene of the crime, there was a woman in red with a very special hair color. They couldn't help thinking of Chi Yong's colleague Wang Li, who also had red hair.
