Thirteen Years of Dust 尘封十三载 Episode 7

Ma Chengqun has been detained seven times and has the habit of killing animals. Wei Zhengrong felt that Ma Chengqun was not a good person when he saw the photos of Ma Chengqun. Someone from Suzaku Lane called the police, saying that there was a disturbance at Ma Chengqun's house. Ma Chengqun bought a few bottles of gasoline and made a fuss on the roof to express his dissatisfaction. Wei Zhengrong learned that the house demolition did not meet Ma Chengqun's demands, so Ma Chengqun took extreme measures. Wei Zhengrong yelled with a loudspeaker, causing the crowd to disperse, and then let the others continue to follow the horses. It would be best to chat him out. Wei Zhengrong led Lu Xingzhi into Ma Chengqun's house through the broken window of the back door, and climbed up layer by layer. During the period, Ma Chengqun urinated for a while, which made the two nervous, thinking that he had put gasoline.

Wei Zhengrong went up to the top of the building, and Ma Chengqun noticed the sound of trampling under his feet. He turned around and saw Wei Zhengrong. He immediately picked up the gasoline bottle and threatened him. Stepped on the rope, slipped and fell on the wooden board. The plank was not strong enough to withstand the weight of a grown man, and soon crumbled. Ma Chengqun fell to the third floor, which made Lu Xingzhi stunned, and then he fell to the second floor. Wei Zhengrong and Lu Xingzhi hurried down to see if the man was still alive. Fortunately, Ma Chengqun was fine, and the red mark on his face was not blood. Wei Zhengrong couldn't help but suspect that it was paint. In 2010, An Ning came to the police station to look for Lu Xingzhi, and looked at the photos of the case.

Wei Zhengrong lied that he was going to the library to work overtime, Zhuang Zhuang guessed that he was going to investigate the case with Lu Xingzhi, and found a reason to follow him out. Later in the car, Zhuang Zhuang said that he wanted to be admitted to the police academy, and Wei Zhengrong was so angry that he sprayed him with water. Hu Haixia has always disapproved of Wei Zhengrong being a criminal police officer. If her son also goes to the police academy, she will probably be furious. Zhao Zhengming's investigation found that Ma Chengqun had six apartments under his name, all of which were in good locations and good neighborhoods. The neighborhood where he often lived happened to be the neighborhood where Wang Nannan lived. Lu Xingzhi divided people into six groups and went to investigate at the same time, but in that community, Ma Chengqun was not found. His wife was about to divorce him, and said that Ma Chengqun hadn't come back for a long time, but his son said that he just came back a few days ago.

Ma Chengqun's son also has a flat under the name of Jiangshan District on the North Bank. Lu Xingzhi immediately took people to Jiangshan on the North Bank. Ma Chengqun was also not found, but according to the clues provided by insiders, Ma Chengqun must have driven a long distance in a large car. Lu Xingzhi asked Zhao Zhengming to keep an eye on this man until he got through to Ma Chengqun. Wei Zhengrong stayed in the public bathing pool and finally found Ma Chengqun. He called Lu Xingzhi and told him about it. In 1997, Ma Chengqun was taken back to the police station for interrogation. The police also found a hammer from his home. Although it basically matched the scar on the victim’s skull, the hammer was very clean. At that time, almost every household had a hammer like this. It's hard to tell if it was the murder weapon.

Ma Chengqun said that he built a house overnight at home, and according to the two old people, Ma Chengqun did not lie. Ma Chengqun knew something about Du Mei, and he insisted on taking a bath before he would tell, but Lu Xingzhi finally took him there. Ma Chengqun said that Du Mei used to work in the Dafuhao Bathing Center and was said to be the number one there, but then she left without saying a word. Lu Xingzhi brought Ma Chengqun back to the bureau, and Wei Zhengrong called Guo Shengli after taking a bath, but he didn't get any useful information, so he concluded that Ma Chengqun was lying. Lu Xingzhi told Wei Zhengrong his analysis. He felt that Ma Chengqun was not lying, but Wei Zhengrong was used to it and thought that the things he read were all made up.
