When Guan Hongfeng went to the community to observe again, he noticed a notice posted in the community prohibiting the entry of takeaway delivery vehicles.The deceased female was identified as a cleaning lady named Xie Jing. When the police entered her rental house, they found that the footprints at the scene were the same as those at the place where the body was dumped.The place where the body was dismembered was in the bedroom. The murderer used the mattress as a sponge to dismember the body, so there was a lot of blood and some missing organs on the bed.Zhou Shutong couldn't stand the bloody scenes, so Guan Hongfeng considerately asked her to find her landlord.When she came back, she found a man wearing a red and white leather jacket and a red helmet across from him. She immediately thought of the characteristics that the security guard had told her.After seeing the police, the man suddenly turned the front of his motorcycle and drove away.

Zhou Shutong informed Zhou Xun, who drove out to chase people.Finally, Zhou Xun arrested the injured suspect at the street corner.The suspect’s name is Wu Hao, male, 25 years old, and Xie Jing’s boyfriend.During Zhou Shutong's interrogation, Wu Hao nervously said what did Xie Jing tell you.Everyone suddenly realized that the murderer was not Wu Hao, otherwise he would not have asked what Xie Jing said.It turned out that Wu Hao was a car thief, and Xie Jing threatened to call the police after discovering his identity, so Wu Hao ran away when he saw the police.Guan Hongfeng kept observing the murderer's psychological safety zone, and finally guessed that this person was a user who was online 24 hours a day but had not logged in recently. He raised cats and smoked. He was between 25 and 28 years old and 1.7 meters tall.7. A man who weighs 90 kilograms and lives alone with a manual transmission.

Zhou Xunyi stated the above conditions to his men and ordered them to search within an eight-kilometer radius of the body dump site in the community.When Guan Hongfeng and Zhou Shutong went to the construction site where the body was dumped for the first time, they suddenly thought: The murderer could see this construction site, so he chose the location here!Based on this condition, the scope was narrowed to five communities. When Guan Hongfeng came to a certain community, he found a white domestic cat under a manual BYD car. He quickly determined that this was the suspect's car.At this time, behind them, the criminal saw Guan Hongfeng and Zhou Shutong surrounding his car, and he slowly took out the ax in his bag.

Zhou Xun arrived suddenly. Seeing that there were many police officers, the criminals fled quietly.The BYD driver's name is Wang Chen, a resident of Community 206.Several people searched for the address and came to room 206, where they found the body parts of the head and right arm in the refrigerator.Xiao Wang asked the real estate agent and found out that this was a shared house. Wang Chen's roommate was named Gao Yuan, a 26-year-old fast food restaurant employee.Wang Chen is a game tester and usually works at home without leaving home.There was a homemade kidney dialysis machine in the room, and Guan Hongfeng immediately concluded that the murderer was Gao Yuan!He took advantage of his position as a food delivery boy to put the body parts in take-out boxes and move them. The reason why he did not go through the main entrance was because take-out was not allowed in that community.

Gao Yuan did not have the key, so it was Xie Jing's brother who opened the door. After Gao Yuan killed Xie Jing's brother, he then killed Xie Jing who returned home.While searching the room, the police found Gao Yuan's business license number, 17655.Guan Hongfeng suddenly remembered that the person's work license number for the takeaway call he received was 17655!So Gao Yuan must have discovered Guan Hongyu at home when he was delivering food, and Guan Hongfeng's back felt cold when he thought of this.At this time, at Guan Hongfeng's home, Gao Yuan knocked on the door and shouted Guan Hongyu's name. Guan Hongyu opened the door, and Gao Yuan put a gun against his head.Then, he called Guan Hongfeng and threatened that he had discovered the two brothers' secret, and he asked to have a good talk with Guan Hongfeng.After hanging up the phone, Guan Hongfeng was very nervous. Zhou Xun thought he was tired, so he asked him to go home and rest.When Guan Hongfeng returned home, he asked Gao Yuan why he killed Wang Chen and Xie Jing.

Gao Yuan scolded them as cockroaches who lived in a dark and humid environment all day long. They had a healthy body but didn't know how to live a good life, but they still worked hard despite having kidney disease, so those people didn't deserve to live.Gao Yuan was blinded by jealousy. He pointed his gun at Guan Hongyu, sarcastically saying that he was also a cockroach living in the dark and a wanted criminal. Killing him would be regarded as eliminating harm for the people.
