The next day, Chen Shi sent the crashed car to the 4S shop for repairs, and took the car to the Municipal Bureau.
The 10.7 headless female corpse case has just been opened, and just after the discussion meeting on the merits of the case in the morning, Lin Qiupu still held the argument, believing that the case points to Jia, a wanted criminal who is currently in a coma, regardless of geography or evidence, and the investigation is centered on Jia.
He also explained the work of Lin Dongxue and Xu Xiaodong. The two were responsible for assisting Chen Shi to investigate. Hearing the news, both of them were very excited. One was because Lin Qiupu had changed his attitude and was willing to cooperate with Chen Shi; the other was excited. Partner with Lin Dongxue.
When Chen Shi arrived, the two waited for him at the entrance of the Municipal Bureau. Xu Xiaodong said politely, "Did Brother Chen have breakfast? I invite you!"
"Why are you so happy?" Chen Shi asked with a smile.
"Of course I am happy to investigate the case with Brother Chen. I am free and have the opportunity to do meritorious service, and..." He glanced at Lin Dongxue meaningfully.
"Don't be proud, it is not easy to investigate the case with me."
"Understand, walk around and invite you to dinner."
"No, hurry up, let's confirm the identity of the deceased today. Has Captain Peng returned?"
Lin Dongxue said: "He's here, he's starting an autopsy!"
"Don't wait for me!" Chen Shi rushed into the game quickly.
In the forensic laboratory, Peng Sijue and another forensic doctor set up cameras and were recording various data of the corpse. Chen Shi stood outside the isolation curtain and said, "Captain Peng, can I come in?"
"Change clothes!"
"Don't take the knife yet."
Chen Shi put on the sterilized protective clothing, Xu Xiaodong was timid, and said, "I will not go for this autopsy!"
Lin Dongxue put a piece of scented facial tissue on the inside of the mask, and said, "Say!"
Xu Xiaodong smiled bitterly and said: "I can't stand the scene, I'm outside, please feel free to contact me if you have any needs."
"Go and call the police stations in each jurisdiction and ask if there are any missing persons who fit the characteristics recently."
"Good!" Xu Xiaodong walked away like a pardon.
Chen Shi asked Lin Dongxue: "Aren't you afraid?"
Lin Dongxue hesitated, she said: "I'm afraid of this, how can I be alone in the future."
"Good job."
When the two entered the autopsy room, Peng Sijue reproved: "So slow!"
"Sorry, changing clothes took time, let me take a closer look at the corpse first."
"Yesterday, you said that the time of death was more than forty-eight hours..."
"I've mispoken?"
Peng Sijue said blankly: "The liver temperature has just been measured, and the time of death should be more than fifty-eight hours. For now."
Chen Shi didn't react at once. After thinking about it, he realized that Peng Sijue was actually joking. He smiled and said, "Thank you Captain Peng for your approval."
"Being less proud, judging the time of death is nothing more than the basic skills of forensic medicine."
"Yes, yes, I can only look at this, and other things, I'm just going to make a fool of myself."
Chen Shi checked the skin of the corpse, focusing on the scar on his wrist. There was a piece of rope on the shelf next to it. Another forensic doctor explained: "The rope was brought back by Team Lin last night. We compared it. , Basically agree."
Chen Shi picked up the rope and compared it, and said, "It does match, but it does not mean that it is this rope. This kind of nylon rope is used for long-distance transportation and can be bought everywhere... Is the binding posture clear?"
"We were just discussing this." The forensic doctor picked up a white board with a sketch on it. The deceased had been twisted and tied up from behind.
Chen Shi looked at the picture and groaned, and said, "No, what's the explanation for the tie marks on the ribs and the back?"
"Maybe it's an extra bundle." Peng Sijue said.
Chen Shi felt the binding marks on the surface of the corpse and said, "Look, the binding marks are not uniform. The ribs are heavier, the edges of the back are lighter, and the binding marks on the back are interrupted by a large piece."
"Padded other things." Peng Sijue had considered this a long time ago.
"What's the cushion? It should be a hard object, otherwise the binding marks will not disappear completely..." Chen Shi looked at another empty iron bed, walked over and said, "Who is more dedicated, come up and lie down? a bit."
Peng Sijue looked at Lin Dongxue, and Lin Dongxue said, "Why do you see me?"
"You are a woman!"
"What's wrong with the woman?"
"The deceased is also a woman!"
Lin Dongxue was defeated by his logic, so she had to dedicate her life to solving the case, but Chen Shi said, "No, Captain Peng, come on!"
"Refuse!"
"Lin Dongxue is a girl, and I'm afraid she can't let go. We are both masters, so you should come."
Peng Sijue thought for a few seconds before he walked over and lay on his back on the iron bed. Chen Shishi made a rope gesture and said: "Like this, tie your hands and feet under the table, and then add another one on your body... There will be a binding mark on the edge, indicating that the thing below is narrower than the body, and the figure of the deceased is not fat, but something narrower than the body? What could it be?"
"A stool!" Lin Dongxue said.
"But the stool is not very common. There used to be a lot of them. Who still uses this now?" said the forensic doctor.
Peng Sijue said: "When we collected the evidence for the second time, we found that there was slight rust on the hands and legs of the deceased, which was ferroferric oxide."
Chen Shi immediately reacted, "The new rust is iron trioxide, and Chen rust is iron tetroxide. It seems that there is a metal support under this thing, and it is stained with rust... Iron brackets, stools with iron brackets?"
Lin Dongxue took out her mobile phone and searched, and exclaimed: "Ah, why didn't I expect it! Look, every unit has this thing!"
She raised the phone, above it was the integrated dining table and chair commonly seen everywhere in canteens, and underneath it was an iron bracket.
Peng Sijue helped the frame of the mirror and said in deep thought: "This kind of integrated dining table and chairs are generally not bought by families. The murderer was in a certain unit with a collective canteen."
Lin Dongxue said: "Then we should immediately go to the unit where the deceased was to find out."
"Do you know who she is?" Chen Shi asked back.
Peng Sijue said: "Continue the autopsy!"
Several people came to the corpse, and Peng Sijue inspected the deceased’s neck and said: “There are regular jagged flaps on the cross section. It seems that the head was cut off with a saw.”
"I told Team Lin yesterday about this." Chen Shi said lightly.
"There was no obvious trauma to the whole body, and the cause of death was..."
"My opinion is postural suffocation."
"Can you stop talking!" Peng Sijue glared at him, "Xiao Wang, help me turn over the body."
After adjusting the position of the corpse, Peng Sijue pressed the plaque on the back of the corpse with his hand, and said: "The plaque has spread, and it has been moved after death."
Then he noticed a small burn mark under the side ribs of the corpse. Chen Shi also noticed it. The two were staring at it almost head-to-head. Peng Sijue straightened up and said, "You blocked the light!"
Lin Dongxue covered her mouth and sneered.
"It was burned, wounded during his lifetime, and there seems to be soot on it." Peng Sijue said while sampling with a cotton swab.
Chen Shi touched the small piece of burned skin and said, "This burn mark shouldn't be the result of a cigarette butt being pushed up directly. It was caused by someone accidentally dropping soot on it."
After the examination, several people turned the corpse over again. Peng Sijue used tweezers to expand the vagina of the corpse and checked with a flashlight. Then he said: “There was a large area of scratches on the vaginal wall. Behavior... It may be multiple people."
"What position?" Chen Shi asked.
Lin Dongxue rolled her eyes, "Why are you always interested in this?"
Peng Sijue said calmly: "Scratches are all concentrated on the ventral side."
"So, it should be entered from the front, combined with the traces of bondage on his body, the deceased was gang-raped by a group of people after being tied up."
"But there are no obvious scars on the body. I have identified many rape cases and were forced to leave more or less injuries on the body."
"Maybe the deceased was unconscious at the time, is it possible that he drank alcohol?"
Peng Sijue touched his chin to consider Chen Shi's words, and then said to his assistant: "Prepare for anatomy!"
