Wang Changjiang has been working as a forensic doctor for many years and has seen all kinds of corpses.
I have seen all kinds of corpses: soaked in water, burned in the fire, dried in the sun, buried in the soil.
But the corpse in this case was the first to be skinned alive by violent means.
The pain-sensing nerves of the human body are actually concentrated in the dermis. There are no pain-sensing nerves in muscles and fat.
In other words, the most painful time for the victim is actually when the murderer is skinning him.
Afterwards, the skin was peeled off and the body was crawling on the ground. In fact, there was no pain.
But looking at his own flesh and blood crawling, the fear should be beyond words.
"Is there anything else?"
"One more thing, we have detected sedative ingredients in the blood of the deceased, that's about it."
"Okay, next Old Liu, let’s talk about it now.”
Liu Guodong coughed twice and straightened up: "There are not many clues in the current investigation. The first is fingerprints."
"We found a total of thirteen fingerprints at the crime scene, and all of them were successfully identified. "
Liu Guodong operated the projector, which showed the identification and comparison results of fingerprints: "They are all employees in the lumber factory."
"The locations where these fingerprints were collected are all square wood, or. No fingerprints were collected on the corpses or human skin from the forklifts and other tools in the factory.”
“After the results came out, we also confirmed that we had communicated with the Action Team 2. These people were resting in the dormitory last night. , looking at it now, there is no time to commit the crime.”
"The other one is the trace evidence in the hot fight."
Since the criminal investigation detachment built the trace evidence analysis laboratory, it can be used in basically every case.
For example, in the last corpse dumping case in the garbage dump, the unique clay of Beishan area was found in the box containing the body, and the location of Beishan was locked.
Although judging from the final result of solving the case, this clue did not play a big role, but the murderer had been camping in Beishan. If there are no other clues, then this is the most important clue.
“We collected a fibrous material on the skin, which should be some kind of clothing or fibrous tissue of cotton.”
"There is a question here, how did the murderer get people into the lumber factory?"
"Where are his clothes?"
"This question, I discussed with Team Leader Ren Qiang However, he has some guesses. I won’t go into details. Let’s talk about another clue, the footprint identification and analysis results.”
“Lu Chuan’s very detailed analysis of the footprints left by the murderer at the scene. From the blood spattered on the wall during the skinning process, we roughly restored some of the characteristics of the murderer."
"Adult male, between 1.82 and 1.84 meters tall, and aged between 1.82 and 1.84 meters. Between the ages of 25 and 30, the strength contrast between the footprints is obvious, the leg muscles are well developed, the height of the blood spatter and the traces of the blood spatter on the wall indicate that the murderer's arm strength is very strong, and the opponent's physical fitness is excellent, weighing over 100 Kilogram to one hundred and twenty kilograms, with a low body fat percentage, and should be a very strong body type.”
Normal footprint analysis is unlikely to be able to analyze the opponent's body shape. Characteristics such as fatness and thinness are difficult to determine.
But the results combined with blood stain morphological analysis are different.
The shape of the blood sprayed by the murderer during the killing process can not only judge the angle at which the murderer drew the knife, but also the strength.
“Based on the blood stains on the ground and the direction of the blood spray on the wall, we determined that the murderer should have his back to the wall at the time, forcing the deceased to kneel on the ground and peeling the skin from the back.”< br>
While talking, Liu Guodong made a demonstration movement with both hands.
After Qin Yong heard this report, the pressure in his heart suddenly eased.
Now that the murderer’s height and body characteristics are known, there will be a direction for the investigation.
In particular, Kong Wu’s powerful image, ranging from 1.82 to 1.84 meters, will make subsequent work much easier.
The next step is the report from the action team.
The action group, Sun Jun's group is mainly responsible for the surrounding visits and investigations and the investigation of surveillance videos. "Let me first report on the investigation of the surveillance video."
The projector behind Director Sun was turned on: "The first is the surveillance video of the lumber factory. It is in a damaged state, and no useful video has been extracted."
"When was it damaged? ?”
Sun Jun understood Qin Yong’s question and wondered whether the murderer might have damaged the surveillance.
“The monitor was not damaged recently. I confirmed it with the security guard. I mentioned the monitor to Zhang Xiaofeng a long time ago, but it has not been repaired.”
"There should be no problem in this regard."
Qin Yong thought for a while and nodded: "Continue."
"We found some video data from the surrounding surveillance."
< br>“But because of the angle, some people only face their own courtyards and gates, and cannot take pictures of the road conditions at all.”
“Furthermore, because the door opening of the lumber factory is not in the same direction as other factories. On a road..."
Sun Jun opened a photo: "In this direction, there is only the gate of a lumber factory."
"There is no progress in this area. Besides, here."
Sun Jun continued The photos that came down cheered up Qin Yong and others.
“Is this?”
“Climbing traces!”
This is the biggest discovery of Sun Jun's group.
“Yesterday, we conducted a detailed inspection of the entire factory wall.”
Sun Jun enlarged the photo: “Looking at the reaction from the security guard at the gate, the height of the factory courtyard wall is not high. It is possible to climb over. "
"In addition, the security guard confirmed that no strangers passed the gate when the crime occurred yesterday. As Lao Liu said just now, how did the murderer enter the courtyard? "
“Have you seen the current survey?”
"Not yet," Liu Guodong shook his head. He only knew this news now.
"Let Lao Bai... no, let Lu Chuan go over and take a look."
"Yes."
Sun Jun continued to introduce the situation: "In addition, the surrounding factories We have also conducted a rough survey of the people inside, and have not found any problems with beatings for the time being.”
“Later, we will conduct a more focused investigation based on the physical characteristics of the murderer given by the current investigation. .”
There are signs of climbing on the wall. Is it possible that the other party left fingerprints or hair?
A group of discoveries is valuable.
"How about the second group?"
Ren Qiang's group is responsible for investigating Zhang Xiaofeng's interpersonal relationships and questioning the staff in the lumber factory.
“There are some discoveries.”
After a day of intense work, not only did the site survey office gain something, but the first and second groups also made many discoveries.
“First, we have conducted detailed inquiries and screening of the people inside the lumber factory, and we can basically rule out the possibility that the murderer is among the existing workers.”
“Two There are two reasons. First, these people were resting in the dormitory when Zhang Xiaofeng was killed yesterday, so they can testify against each other. Second, I have seen all of these people, and there is no one with a similar body shape to the one given in the current survey. "
"Second, we have restored the whereabouts of the victim Zhang Xiaofeng." (End of this chapter)
