After crossing the cordon, Lu Chuan climbed directly onto the hill.
There are still construction machinery staying at the scene, and because the body was found after construction, the surrounding area has been destroyed. From the perspective of on-site investigation, it is difficult to find traces of the suspect through the scene. Not likely anymore.
The reason why Lu Chuan wanted to observe the scene was to observe the depth of the corpse pit.
“The pit is about 1.5 meters deep. Based on the traces of soil around the pit, it can be basically determined that the suspect dug it with a shovel and the like. There are no traces of mechanical excavation.”
Wang Gang introduced to Lu Chuan their on-site inspection situation.
Lu Chuan had no other opinion on this point.
No matter how long time and space have existed, from a health perspective, there must be some differences between the soil where the body is buried and the surrounding soil.
Ordinary people may not be able to tell it, but experienced detectives can make judgments.
Lu Chuan knew Lu Chuan, an advanced criminal police officer from the Criminal Police Brigade of Tianshan District, who was also a veteran and very experienced.
“After the body was discovered, we also found a rotten thread glove in the corpse pit.”
Wang Gang stood on the edge of the corpse pit and pointed inside and said.
"Gloves?"
Lu Chuan cheered up upon hearing this: "Above or below the body?"
"Above the body, the murderer should have dug a hole to bury the body. Then he threw it inside."
Wang Gang gestured at the situation: "After the autopsy, it was estimated that the death time of the body was about ten years."
"However, because it is so long ago, there is still some deviation in the time of death."
Lu Chuan squatted by the pit and continued to observe: "Has the cause of death been determined?"
"Suffocation, corpse There were no injuries on the body, but the hyoid bone was broken. It was determined that he died from suffocation. "In this week, Wang Gang basically didn't get much rest. The entire Tianshan District Criminal Police Brigade was surrounding this person. The case has been transferred, so a lot of the basic information has actually been figured out.
However, the identity of the deceased has never been determined, and no matter how many clues there are in the case, it is useless.
No one knows who died, let alone a suspect.
There were not many clues at the scene. After Lu Chuan watched it for a while and studied it, he followed Wang Gang to the Tianshan District Criminal Police Brigade.
In the autopsy room, Lu Chuan saw the corpse.
"Team Lu, this is the video of when we found the body, as well as the surveillance data of the autopsy."
The forensic doctor of the Tianshan District Criminal Police Brigade is called Guo Jianfeng, who is about the same age as Wang Changjiang and has more experience. It’s also relatively rich.
Guo Jianfeng, wearing a white coat, stood next to the corpse and introduced Lu Chuan in detail his dissection process.
"The deceased woman was between 30 and 35 years old at the time of death, and was 1.67 meters tall."
Guo Jianfeng was tall and spoke with a deep voice.
"There are no obvious injuries on the surface of the body. The hyoid bone of the deceased was broken. It is initially determined that the cause of death was suffocation."
Lu Chuan was already wearing a mask and gloves at this moment. He put on a white coat and got close to the body to observe the surface of the body.
"Are there any special findings?"
Guo Jianfeng nodded: "Yes, we found some residual ingredients of sleeping pills in the stomach of the deceased."
"Sleeping pills?"
"Yes, sleeping pills. Although the corpse may have been buried underground for more than ten years, the ingredients of the sleeping pills have been in the stomach and are protected by the vacuum bag, so they have not been completely digested."
"Are there any signs of violation?"
"This..." Guo Jianfeng shook his head, "This is not particularly certain, after all, it has been too long."
"Many traces cannot be found."
Lu Chuan nodded, no Keep asking.
Lu Chuan already knew on the way here that the forensic doctor here had collected DNA information from the corpse, but no relevant information was found.
And before the body was sealed in a vacuum bag, its clothes had been stripped off.
There are no other decorations on the body, such as rings and necklaces.
"Here..." Lu Chuan's attention was attracted by the right arm of the corpse.
Guo Jianfeng also noticed: "Lijun Lu, what's wrong?"
"Have you taken it apart?"
"This... no."
"There is a fracture here, open it up!" Lu Chuan decided decisively.
“If it is a normal fracture, nothing may be found, but if it is a severe fracture, it is very likely that a steel plate will be implanted inside.”
Lu Chuan’s eyes were bright: “If the deceased If a steel plate was inserted before death, it is very likely that a medical record will be left in the hospital. "
This point...
Guo Jianfeng and Wang Gang looked at each other, it was indeed possible.
But...
Guo Jianfeng raised the deceased's arm: "How did you discover the fracture?"
"The deceased's right arm was thicker than his left arm."
Lu Chuan pointed to the corpse: "Generally speaking, for right-handers, the muscles of the right hand are more developed and the bones are thicker, but the left arm is thicker than the right arm."
"But the deceased's right arm is thicker than his left arm, and the skin color is lighter, so it is possible that the deceased had a fracture before his death."
Guo Jianfeng glanced at Lu Chuan.
It is said that Lu Chuan's ability in autopsy is no worse than that of ordinary forensic doctors. Now it seems that where is the difference, he is better than himself.
If you say dismantle it, then dismantle it!
According to normal autopsy procedures, the limbs are not included in the anatomy.
But now this situation is quite special.
Although Lu Chuan said it would be dismantled, it was Guo Jianfeng who was the surgeon.
Because the corpse was air-dried in a vacuum bag, cutting it was like cutting through leather.
Guo Jianfeng's technique is very careful. When he dissects the limbs, he cuts along the muscles.
This kind of knife technique not only saves labor, but also causes minimal damage to the body, making it easier to handle later.
Stab!
After two stabs, the three of them heard a sharp stabbing sound.
“There is a steel plate!”
Guo Jianfeng’s face lit up.
Wang Gang came over: "Really?"
"In this case, it is possible to find out the identity of the deceased."
Guo Jianfeng continued the autopsy, while Lu Chuan walked aside and looked at the vacuum bag that sealed the body.
As Wang Gang said, the vacuum bag that sealed the body was very thick and had not degraded even after being buried underground for ten years.
It's just that the surface is a little foggy.
When the corpse was sealed, it was curled up in the bag. Now you can still clearly see the outline of the human body.
Standing next to the bag, Lu Chuan showed a thoughtful expression.
Why did the murderer seal the body in a vacuum bag?
Killing is actually very simple.
The key is how to dispose of the body.
The vast majority of criminal suspects are arrested because there was no proper handling or traces left during the disposal of the body.
Sealing the corpse in a vacuum bag...
How did the murderer come up with this method? (End of this chapter)
