Du Mei was killed, and the murderer put her in a strange pose, and there was an HB pencil at the scene. Wei Zhengrong led Lu Xingzhi and others to the scene of the crime, and the crowd around the scene talked a lot, accusing the police of not doing their job well. Wang Zhengquan suspects that this was done by the same murderer as in the Liu Meng case, because so far, the modus operandi is highly consistent. Lu Xingzhi asked if he wanted to visit the masses, but Wei Zhengrong vetoed it. Now that the masses are all overwhelmed, I'm afraid they won't cooperate. However, Wei Zhengrong discovered that the deceased had paint on his hands, so he asked Lu Xingzhi to ask the machine of the painting machine of the electric machinery factory. After confirmation, the victim was Du Mei, a female employee in the painting workshop of the electric machinery factory. Thinking of being found murdered today.
Du Mei also has a daughter named Ning Ning, who is three years old this year. Lu Xingzhi went to knock on the door of Du Mei's house, but no one answered. Wei Zhengrong also came and kicked open the door. The master and apprentice searched around the room but found no sign of the child, and then searched everywhere. Later, Lu Xingzhi found the little girl unconscious in the wooden cabinet. Ningning's feet were covered in mud and she was not wearing shoes. Lu Xingzhi sent her to the hospital. Yao Le, who was not suspected, was released, and Wei Zhengrong asked people to vacate the large conference room for a meeting. In 2010, Yao Le changed his name to Yao Shuo and became the general manager of Chasing Dream Media Company. He said that he had several relationships with Wang Nannan. Wang Nannan probably misunderstood their relationship, so on the 29th she Will leave angrily.
As for Lu Xingzhi's other questions, Yao Shuo did not provide any effective information. Lu Xingzhi left him his phone number, hoping that Yao Shuo would call him when he remembered something. Not long after Lu Xingzhi returned to the bureau, Yao Shuo called him and said that Wang Nannan might know the murderer. Yao Shuo was unwilling to go to the Public Security Bureau, so Lu Xingzhi took the initiative to go to the company to find him. Yao Shuo said that Wang Nannan met a QQ netizen some time ago, and she seemed to have talked a lot with him. Lu Xingzhi took the QQ password and account number from Yao Shuo, and went back to the bureau to find out the Internet protocol address of the last login of this netizen named HB. After that, Lu Xingzhi and Zhao Zhengming went to No. 167 Jiefang South Road, Nandu City.
Wei Zhengrong also came, and it was inevitable that we would get to know each other in the future, so Lu Xingzhi introduced him to Zhao Zhengming. Zhao Zhengming went to check the spot first, and Lu Xingzhi and Wei Zhengrong asked the boss for registration records and surveillance records on June 29. Next to it is the old long-distance bus station. Wei Zhengrong said that the other party probably had already planned it. They checked the surveillance and found the face of an old acquaintance, as if they had returned to 1997. One morning in 1997, Lu Xingzhi woke up to find that Yang Man had already woken up early to make breakfast. He was very surprised. Although the breakfast made by Yang Man was not delicious, he still ate very cleanly. Yang Man suddenly felt guilty. She actually tasted the food she made, and it was not delicious at all, but she was angry that Lu Xingzhi was always so busy, so she deliberately didn't say it. She didn't expect Lu Xingzhi to eat all these things.
Lu Xingzhi and Wei Zhengrong visited the masses and learned that a man approached Du Mei ten days and a half months ago. This man is also from the electrical machinery factory, and he is wearing overalls. The two went to the factory to inquire again, and found that the man was called Ma Chengqun. Du Mei had been followed by him as soon as he arrived. Ma Chengqun has a bad reputation and is a recognized hooligan and black sheep. A female worker also said that Ma Chengqun once gave Du Mei a bra, and after being scolded by Du Mei, she became angry and said that she would kill her sooner or later. Ma Chengqun has been detained seven times, and he is not a good person at first glance.
