When Chen Shi and Lin Dongxue returned to the neighborhood, they saw police cars and a lot of people from a distance. There was a small river at the door of the neighborhood. To be precise, it was just a ditch with a bridge on it. The body was stuck on the bridge.
Xu Xiaodong complained as soon as they met: "Why leave me behind and go back by yourself."
"I want to send the corpse, stop complaining, let's eat!" Chen Shi handed him the packed claypot rice.
Seeing the food, Xu Xiaodong's grievance disappeared, and he squatted down beside him to eat.
The corpse was picked up by the police, lying on a tarp on the shore, Chen Shi took a look at the cloth on the corpse. The deceased was wearing a security uniform. He was a middle-aged man in his forties. The blood on his chest was covered. The river washed very lightly, and there was a hole in the center of the blood stain that seemed to be a gunshot wound.
Chen Shi put on his gloves and checked the corpse’s mouth. His mouth was tightly closed and his respiratory tract was very clean. Generally, the drowned person would have pink crab-like foam. Looking at his hands, his hands were not tightly clenched, and there was no mud between his fingers. sand.
He said: "The time of death was very close to that of another corpse. It was killed first and then the corpse was thrown here."
Lin Dongxue said: "The deceased looked heavy. There was a distance from here to the gate of the community. If the murderer is a woman, how can I drag it over?"
"He is about the same height as me, you can test it out by an experiment."
Xu Xiaodong interjected, "The security has just arrived and has confirmed his identity. It is the old Wang who was on duty last night. Then they said that because the toilet is far away, the security often comes to this river at night to solve problems."
"If someone fired a shot while urinating, it is unlikely to be from the front... Dongxue, let's turn the body over."
The two turned over the corpse and saw that there was also a bullet hole on the back, which is the entrance of the bullet and which is the exit of the bullet. This needs to be identified by a forensic doctor. Generally, there will be gunpowder particles remaining at the entrance of the bullet.
Chen Shi asked the police comrade to come over with a marker, and then counted the spine of the deceased, and asked Lin Dongxue to point a point on the corresponding place on his body.
Lin Dongxue said: "Aren't your clothes dirty?"
"It doesn't matter, you can buy one more clothes for dozens of dollars."
So Lin Dongxue clicked a point on his back, and then Chen Shi turned the corpse over, using the deceased's ribs as a reference, let Lin Dongxue click on the corresponding place on his body, and compared the two bullet holes, and found that the ballistic trajectory was inclined, and the back was high. , The front is low.
Chen Shi asked everyone to spread out first and look for footprints on the ground. There was a pair of leather shoe footprints ten centimeters by the river, which were very close to the size of the dead man’s shoes. Chen Shi stood in a parallel position and said to Lin Dongxue: "The murderer will stand where?"
"There are no obvious footprints on the ground."
"That's standing on the concrete floor above."
Lin Dongxue stood there, simulating the actions of the murderer, and roughly calculated from the angle of the shot, it should have been shot from the side of the road above, and then the bullet fell into the water.
To be on the safe side, Chen Shi still asked the police to go to the other side to look for it. The police said: "The criminal police really have a lot of ideas, and they can restore the scene without equipment."
Chen Shi speculated: "The murderer should have waited for the security to come out in the community and took the opportunity to kill him. The corpse fell into the water. Then she calmly deleted the surveillance records... Alas, this person died unjustly. "
The corpse was put in a bag and placed in the car. There were people coming and going. Chen Shi took a picture carefully, saying that there was no need for protection.
The results of this autopsy did not come out. It turned out that Peng Sijue had no experience with gunshot wounds. He went to the material evidence center to find a special ballistics expert to analyze. However, judging from the warheads found at the scene, the gun used by the murderer was the Russian-made Macallo. Husband pistol.
The day passed peacefully. Everyone gathered in the office the next morning. Peng Sijue handed over the autopsy report, saying: "The deceased Song Yuwen's death should be around 11 pm on July 25. He had three gunshot wounds on his body, all In order to cause death and injury, the bullet entrance is all on the front chest, but the ballistic A is almost perpendicular to the body, and the shot should be shot in a standing position. The inclination angle of the ballistic B and C is close to 30 degrees, and the amount of bleeding is relatively small. Therefore, these two The trajectory may be that after the deceased fell to the ground, the murderer made up his gun, and was separated from trajectory A for about ten minutes."
Chen Shi said: "In these ten minutes, what will the murderer do? Speak? Will the deceased die if the first shot is shot in?"
"I shot through the main vein and lung lobes, but I should be struggling for a while. There are signs of struggling on the floor. It is a long, scratchy blood stain. It was covered by a corpse at the scene yesterday... In addition, I sent someone to go. During the resurvey, two things were found. There were fine leather crumbs on the floor and on the chest of the deceased. In addition, a long brown hair was found on the coat of the deceased on a hanger."
"Leather crumbs? Why are there leather crumbs?" Chen Shi thought.
Lao Zhang picked up the earlier bag, put his hands into the bag like a gun, and said, "Could it be that the murderer hid the gun in the bag and fired directly."
"That's right!" Chen Shi praised.
Peng Sijue went on to say: "There are still some findings that may not be related to the case, but I still mention that there were old injuries on the deceased, which took about four or five days to form, not more than a week. These old injuries were concentrated on the torso. And on the right arm."
"That's because the deceased had fought with someone, or was attacked..." Chen Shi thought for a while, "this shouldn't be left by the murderer, because based on the time of the missing gun, the murderer had already obtained the pistol four or five days ago. Now, she doesn’t need to attack the dead once to add suspicion to herself."
Then other police officers talked about some of the deceased’s interpersonal relationships. It seemed that the relationship was good. There were more than a dozen friends, and it was very troublesome to find out.
The deceased’s mobile phone could not be recovered. Checking the communication records found that many people had sent him text messages on the day of his death, possibly to congratulate him on his birthday. Chen Shi said: “List the people who sent the text messages. The murderer may be there. ."
Lin Dongxue said: "Could the murderer anticipate this, so he chose to kill on his birthday?"
Chen Shi shook his head, "This idea is too tricky, I don't think it is. From the murderer's actions, killing is more like a crime of passion, because after killing someone, she immediately destroyed the phone and killed a security guard to delete surveillance. If it was premeditated, mobile phones and surveillance can be avoided by her... I think she was the first offender. After killing someone, her head suddenly calmed down, and she remembered to take care of the aftermath."
Peng Sijue supported this view, saying: "During the re-examination, we found that the cup on the table was wiped, but some fibers were left. The preliminary judgment is that it will be a handkerchief made of chemical fiber."
"By the way, where is the deceased's girlfriend? Did you find it?" Chen Shi asked.
