Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

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, including those soaked in water, burned in the fire, dried in the sun, and 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, and 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 seeing his own flesh and blood crawling, the fear should be beyond words.

"Any more?"

"One more thing, we detected sedative ingredients in the blood of the deceased, and that's probably it."

"Okay, Lao Liu, come and talk here."

Liu Guodong coughed twice and straightened his body: "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 were successfully identified."

Liu Guodong operated the projector, which showed the identification and comparison results of fingerprints: "They are all employees of the lumber factory."

"These fingerprints were collected from square logs, or from forklifts and other tools in the factory. No fingerprints were collected from corpses or human skin."

"After the results came out, we confirmed and communicated with the second operation team. These people rested in the dormitory last night. Looking at it now, there was no time to commit the crime."

"The other one is trace evidence on the hot spell."

Since the Criminal Investigation Detachment built a trace evidence analysis laboratory, it can be used in basically every case.

For example, in the last case of corpse dumping in a garbage dump, the location of Beishan was determined after the unique clay of the Beishan area was found in the box containing the body.

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 mill?"

"Where are his clothes?"

"I discussed this issue with Team Leader Ren Qiang. He has some speculations. I won't go into details. Let's talk about another clue, the results of the footprint identification and analysis."

"The footprints left by the murderer at the scene, Lu Chuan's very detailed analysis, and the blood spattered on the wall during the skinning process, we can roughly restore some of the characteristics of the murderer."

"Adult male, height between 1.8 meters two to 1.8 meters four, age between 25 and 30 years old, obvious strength contrast between the footprints, well-developed leg muscles, blood spatter height and spatter on the wall The traces show that the murderer’s arm strength is very strong, and the opponent’s physical fitness is very good, weighing between 120 kilograms and [-] kilograms, with a low body fat rate, and he should be a very strong body.”

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 combined with blood stain morphological analysis, the results are different.

The shape of the blood sprayed by the murderer during the killing process can not only determine the angle at which the murderer drew the knife, but also the force.

"Based on the blood stains on the ground and the direction of the blood spray on the wall, we determined that the murderer had his back to the wall, forced the deceased to kneel on the ground, and started peeling off the skin from the back."

While talking, Liu Guodong made a demonstration gesture with his 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 investigation.

In particular, Kong Wu's powerful image, ranging from 1.8 meters two to 1.8 meters four, will make subsequent work much easier.

Next is the report from the action team.

In the action group, Sun Jun's group is mainly responsible for surrounding visits and investigations as well as the investigation of surveillance videos. "I'll first report on the investigation of the surveillance video."

The projector behind Director Sun was turned on: "First of all, it 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 system.

"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."

"In this regard, there should be no problem."

Qin Yong thought for a while and nodded: "Continue."

"We found some video materials from the surrounding surveillance."

“But some of them only face their own courtyards and gates due to the angle, and cannot take pictures of the road at all.”

"Moreover, because the door opening of the lumber factory is not on the same road as other factories..."

Sun Jun opened a photo: "In this direction, there is only the gate of a lumber factory."

"There's not much progress on that, besides, here."

The next photos of Sun Jun cheered up Qin Yong and others.

"This is?"

"Climb marks!"

This is the biggest discovery of Sun Jun's group.

"Yesterday, we conducted a detailed inspection of the fence throughout the factory area."

Sun Jun enlarged the photo: "Looking at the reaction of the security guard at the gate, the height of the factory courtyard wall is not high, so it is possible to climb over."

"In addition, the security guard made sure that no strangers passed the gate when the crime occurred yesterday. As Liu just said, 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 wait... no, let Lu Chuan go over and take a look."

"Yes."

Sun Jun continued to introduce the situation: "In addition, we have also conducted a general survey of people in the surrounding factories, and we have not found any shooting problems for the time being."

"Later, we will focus on conducting an 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?
One group's findings are valuable.

"How about the second group?"

Ren Qiang's team was 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."

"There are two reasons. First, these people were resting in the dormitory when Zhang Xiaofeng was killed yesterday and can testify against each other. Second, I have seen all these people, and there is no one with a similar body shape to the one given in the current survey."

"Second, we restored the whereabouts of the victim Zhang Xiaofeng." (End of chapter)
