During the conversation, police officer Xiao Li rushed to report the trace analysis and autopsy report:

1. The old fracture of the cadaver leg, the wound on the body surface is obvious and densely distributed, the wound infection is accompanied by severe inflammatory reaction, and the lungs and respiratory tract are suspected of bacteria; The infection is a lesion, and the cause of death is presumed to be acute pneumonia caused by bacterial infection.

2. There were restraint injuries on both arms and neck, and there were life reflections, and trace amounts of propylene components and trace blood stains that did not belong to the deceased were found on the rope used to bind the corpse.

Analysis: It is speculated that the deceased was bound and imprisoned before his death, and his living conditions were poor.

Due to the rain after the incident, almost no valuable footprints were left at the scene, but three regular square depressions were found about 1.5 meters directly opposite the face of the corpse. Traces of acrylic paint were found all around. Based on the acrylic paint left at the scene and the state in which the body was found, I think the murderer is very likely to be engaged in art-related industries, and at the same time, the three regular depressions found at the scene are very likely to be caused by the placement of a drawing board, and Lu Zihan is very likely to be a work of art made by the murderer to satisfy his perverted psychology.

After determining the direction of the investigation, Jiang Chen immediately arranged for the police to investigate the relevant personnel engaged in or studying art around the village, Xiashi Village and the nearby connected villages are relatively poor and backward, and almost all the villagers are engaged in farming or sheep herding, etc., and studying art is an extremely money-consuming profession, considering the economic situation in the village, the murderer is very likely to be an outsider, after visiting, Xiashi Village has indeed come to a painter named Liu Yunyang recently, claiming to be here to collect style, and is currently renting a bungalow vacant from a local villager's house. After confirming the location, the police immediately dispatched, and when they arrived at the farmer's house where Liu Yunyang lived, he was not at home, there were many nude paintings of the deceased in the house, and a large number of dirt marks were found at the bottom of an easel, the shape of the bottom of the easel resembled the dent marks found at the scene of the crime, and the trace inspectors immediately conducted an all-round search of the room.

Jiang Chen: "Immediately contact the investigation team, conduct a search around the village, and arrest suspicious people immediately." ”

Officer: "Yes! ”

Soon, the investigation team found Liu Yunyang who was sketching by the small river not far from the village. According to the trace examination, the acrylic paint found at the scene was the same material as the acrylic paint used by Liu Yunyang, and through the collection of skin scrap on the personal belongings in Liu Yunyang's room, it was found that its DNA was consistent with the DNA found on the body that did not belong to the deceased. In addition, a small amount of hair and suspected herbivore were found on a coat thrown in the corner of Liu Yunyang's room, and the police used the Xiashi Village Committee as a temporary location to interrogate Liu Yunyang.

Jiang Chen: "Why did you kill Lu Zihan?" ”

Liu Yunyang: "I didn't kill anyone, and I don't know any Lu Zihan." ”

Jiang Chen: "The girl in your painting is Lu Zihan, and your painting accurately restores the scene of Lu Zihan's discovery, how can you explain this." ”

Liu Yunyang: "I found her in a no-man's land on the mountain, when she was already dead, and her body was particularly smelly and smelly. I wanted to call the police, but when I got closer and saw that the girl wasn't rotten and beautiful, I was inspired to find a creative direction. So I used her as a model, but her clothes were dirty, so I took them off and threw them down the hill. I really didn't kill people, I was going to call the police when I finished my paintings, and if I had called the police at that time, I wouldn't have been able to paint anything as soon as you came to block this. ”

Liu Yunyang is a painter who is almost paranoid, after interrogation, Liu Yunyang came to Xiashi Village half a month ago to look for creative inspiration, a week ago he found Lu Zihan's body while wandering in the undeveloped no man's land, and perverted the corpse as a model in various poses for his own creation. Liu Yunyang and Lu Zihan had no intersection before, let alone a motive to kill Lu Zihan. Moreover, Liu Yunyang came to Xiashi Village alone half a month ago, and he was not familiar with the place, combined with the cause of Lu Zihan's death, Liu Yunyang did not have the conditions to imprison and torture Lu Zihan. At this time, I noticed a detail in Liu Yunyang's confession, when he found the corpse, the corpse had a fishy smell, combined with the small amount of herbivore feces detected on Liu Yunyang's clothes by the trace examination department, it is very likely that the place where Lu Zihan was imprisoned was related to sheep.

According to previous surveys, most of the villagers in Xiashi Village make a living from farming and sheep herding, so we decided to first check the villagers who raise livestock in the surrounding area. During the investigation, we learned from the villagers that Du Xinru's father, Du Yiteng, is also a big sheep farmer here, and I thought that Lu Zihan was related to Du Xinru's car accident case, so I decided to go to Du Yiteng's house to investigate first. After a while, Jiang Chen and I came to Du Xinru's house, and at this time, Du Yiteng went to clean the sheep shed a little further away from home, and only the neighbor Aunt Wang was here to take care of Du Xinru, who was in a coma. Xiashi Village is close to the mountains, and there are many natural pastures, and the villagers usually set aside a pasture far from the village and build a simple hut to raise their livestock, so that they do not have to worry about the smell of raising livestock or the noise affecting the lives of the villagers.

The police asked Aunt Wang about the Du father and daughter.

Aunt Wang: "Just ask me what you want to ask, Du Yitou and I are small, and Xinru is also something I grew up with, and during the time she was in a coma, I was basically taking care of her." ”

According to Aunt Wang, although the Duiteng family raised a lot of sheep, their financial situation was not good. Du Xinru was almost bankrupt when Du Xinru was in a car accident, but fortunately, there was a kind girl in Du Xinru's class to raise donations for her, so she scraped together enough money to see a doctor, but she still had a leg disability, and she has not woken up yet.

Me: "Do you know the cause of Du Xinru's car accident?" What is Du Xinru's usual personality? ”

Aunt Wang: "It's that god-damn drunkard who ruined our Xinru, our Xinru has been a good boy since she was a child, she took the first place in the exam, and after going to college, she felt sorry for his father who worked hard at home, worked and studied outside, and occasionally sent some money to Du Yiteng."

Come. ”

Although Du Xinru's classmates held a fundraiser at that time, it was only enough to support the cost of the operation, and then the cost of hospitalization fell on Du Yiteng's shoulders, and finally Du Xinru was out of danger two months later, because he could not afford to pay for the hospitalization, Du Yiten had to take his daughter home to take care of him.
