The police's internal network came with relevant information about Yu Dalong, that is, Gu Hai, this person committed the QJ homicide in other provinces, the victim's situation is the same as Chen Chen, he is also a minor, he also has a bruise on his neck, suffocated to death, YD rinsed it with a hose, but it was not flushed, leaving a residue of JY, so Gu Hai's criminal suspicion was determined.

This time, the means were upgraded and 84 disinfectant was used, most likely because when he was engaged in cleaning work, he learned that 84 disinfectant has strong oxidation and can completely destroy the DNA structure.

At the third case analysis meeting, Shui Guochang and Du Lin once again repeated the process of the case according to the evidence supplemented by various people.

At around four o'clock in the afternoon, Chen Chen returned home after finishing his homework at his classmates and was killed by Yu Dalong, who was living in the West Wing, that is, Gu Hai QJ, a fugitive from other provinces.

Later, Lu Chunyan went home and found that her daughter had been killed, Gu Hai was afraid that Lu Chunyan would call the police, so he took a kitchen knife in the kitchen and killed Lu Chunyan, and moved the body to bed and covered it with a quilt.

After that, Chen Zhiping came home from work, had a fight with Gu Hai, and was killed by the strong Gu Hai.

However, there are several important details that remain unclear.

First of all, it is not known in which gap Gu Hai disposed of Chen Chen's corpse; secondly, it is not clear whether the signs of rummaging in each room were caused by Gu Hai or Chen Mo; thirdly, it is not clear who dug the pit where the corpse was buried; finally, what kind of fight took place between Gu Hai and Chen Mo may only be known if Chen Mo is caught.

"Mr. Du found a ring ornament in the pit where the body was buried, and if you can figure out whose ornament it is, you can know who buried the corpse. Qu Mingming added.

Li Xian: "Give that ornament to Gu Amei to identify and see if it is Chen Mo's." ”

The next day, everyone was nervously carrying out the work in hand, and news came from Yongchuan Town, Gu Amei said that the ring was a finger ring, which was given to him by Chen Mo's mother on his eighteenth birthday, which can prove that the person who buried the body was Chen Mo, which also explains why only the bodies of Chen Zhiping and Lu Chunyan were buried in the ground, while the body of Gu Hai (Yu Dalong) was exposed in the bedroom.

A policeman came knocking on the door of the office of the criminal police team, "Team Li, there is a homeless man downstairs, saying that he is looking for you." ”

"Tramp, looking for me? Did he say who he was?" asked Li Xian.

"He said his name was Chen Mo!"

"Oh, Chen Mo......" Li Xiannian muttered, and then reacted, "Chen Mo!?"

Li Xian jumped three feet high from his chair, "Hold him down for me! Don't let him run away!"

The person who came said: "Don't worry, Team Li, he said that he turned himself in, and, depending on his state, he can't run far if he wants to." ”

In the interrogation room, Li Xian and Yu Baofu watched Chen Mo gobble up a boxed lunch.

Chen Mo in front of him was still wearing ill-fitting clothes, but he was so dirty that he couldn't see his original color, his unkempt half-long hair hadn't been washed for a long time, and his hands and face were covered with black oil mud, which was really the same image as a homeless man under the overpass.

Looking at his eating posture, I don't know when the last full meal was.

After three boxes of lunches, and a bottle of pure water, Chen Mo touched his bulging stomach and burped with satisfaction.

"Thank you, Uncle Police. ”

Li Xian looked at Yu Baofu, "Am I that old?"

Yu Baofu said: "He is only 19, and you are in your 30s, so it doesn't seem to be a disobedience to call you Uncle Sheng." ”

Li Xian no longer dwelled on this matter, "Tell me, young man, what's going on in your family?"

As soon as he mentioned the tragedy that happened in his family, Chen Mo's voice began to deepen.

"I heard that my sister's body is in the water tank in the East Warehouse Room, is it true?"

Li Xian: "Yes, buckle it in the water tank." ”

Chen Mo: "No wonder, I never found my sister's body. ”

Li Xian: "Tell me, what happened that day, right?"

"Okay," Chen Mo sorted out his thoughts, "Usually I do odd jobs outside, that day I followed a tour group to do chores for them, I came home at about ten o'clock in the evening, and after returning home, I went directly back to my house, stayed for a while, and was a little hungry at about eleven o'clock, so I went to my mother's to see what to eat." The lights in the house were on, and when I entered the house, I smelled a particularly strong smell of blood, and then I found that my dad was mixed with blood, lying on the floor of the east room, I followed the example on TV, and probed her snort, my dad was out of breath, I was scared stupid, and then I saw blood dripping down the bed, I lifted the quilt and saw my mom also lying on the bed, there was no blood on her face, and my mom was also dead. ”

"I was just about to cry, suddenly I heard a movement in the kitchen, I guess nine times out of ten it is the murderer, I want to avenge my parents, I see a kitchen knife on the ground, there is blood on it, sure the murderer is using this kitchen knife to kill my parents, I also want to use this kitchen knife to avenge them, I picked up the kitchen knife and planned to go to the kitchen and the murderer desperately, but when I went out of the bedroom door, the kitchen knife hit the door frame, 'bang', a person on the kitchen shouted 'who?' , I immediately heard that it was Yu Dalong's voice, he was taller than me and stronger than me, I was afraid that he was not his opponent, so I went back to the bedroom and hid behind the door, and when he came over, I stabbed the back of his head. ”

Li Xian: "Why do you want to use the back of the knife? Don't you want to kill him?"

Chen Mo: "How to say it, two years ago, I was detained in the detention center because of fights, and there was a senior in the detention center who was locked up with the same number who said, if you use a kitchen knife to cut people, 'use a blade to hurt people, and use a back to kill people', which means that the blade of the kitchen knife is too wide, and the center of gravity is on the back of the knife. ”

Li Xian: "Your senior is quite experienced, continue to speak." ”

"Maybe I'm not strong enough, he didn't fall down after hitting me, he fought with me, and he wanted to grab the kitchen knife in my hand, and I don't know how to do it, my arm was cut by a knife, and I couldn't use it anymore," he said and showed Li Xian the dirty bandage on his arm that couldn't see the color, "When he was about to beat him, he suddenly rolled his eyes and fell to the ground, I kicked him twice, he didn't move, he sniffed, and died." ”

"I don't care about him anymore, I started looking for my sister, there is no room in her room, there is a mess on the bed, there is blood, and my sister's clothes are torn, I immediately understood, it must be Yu Dalong's beast that harmed my sister, he is a bastard, it is not enough to harm my girlfriend, but also to my sister. ”

"I searched for my sister all over the house, but I couldn't find it. Later, it was the middle of the night, and I thought I should run away, because I had killed someone, so I wanted to flee to another place. When I was looking for my sister, I found that the kitchen sink was dug up by Yu Dalong, it is estimated that he was going to bury the bodies of my parents, I thought about it, I can't let my parents' bodies just leave them in the house, there is a pit, burying them is also my filial piety as a son, I will first carry my mother to the pit, and then my father. By the way, I also buried my mother's birthday present with my mother. ”
