Chapter 22 Xue Ming's legacy

Huang Qiangmin was in charge of the overall situation. Hearing what Jiang Yuan said, he immediately walked over and asked, "What do you say?"

"Looking at the shape, it's a female pubic hair." Jiang Yuan picked up the hair with a pair of tweezers, observed it under the light, and then put it into the evidence bag.

The deceased was a male, so the sudden appearance of a female pubic hair was obviously a very important clue and evidence.

Director Guan Xi came over and asked, "You said you can tell by looking at the shape?"

"Women's pubic hair is generally shorter and rougher. Compared with the victim's pubic hair, it is easier to distinguish." Jiang Yuan briefly explained.

The director smiled inexplicably, coughed twice: "It makes sense..."

Next to him is a young technician who is still eager to learn, so he casually said: "The armpit hair and beard are also curved."

Lao Yan, who was scanning his fingerprints, laughed with a "poof", looked at the young man who was doing the survey, and said earnestly, "Xiao Yang, I don't know enough."

Everyone in the room smiled mysteriously.

Comrade Xiao Yang couldn't hold back his face, and said in a low voice: "This judgment is not reliable with experience, so it must be scientific."

The director was kind, and asked Jiang Yuandao curiously: "Tell me, what is the scientific basis?"

"The breasts will be more elastic. The cross-section of the armpit hair is elliptical, and the cross-section of the beard is triangular, which is harder..." Jiang Yuan replied casually.

Comrade Xiao Yang was stunned on the spot: "Is someone really researching this?"

The director smiled in satisfaction, and then said to Huang Qiangmin, the team leader next to him: "Send the evidence to the laboratory as soon as possible, and the chain of evidence must be solid."

Huang Qiangmin nodded immediately. He was also worried about the evidence just now.

For the police, the evidence provided by biological examination materials has always been the high-end material evidence.In particular, DNA and fingerprints have strong specificity and a high degree of recognition. In the litigation stage, physical evidence with DNA evidence will also have a higher degree of recognition.

Today's judiciary is required to place more emphasis on physical evidence than oral confessions, which also increases the importance of DNA evidence in disguise.

Jiang Yuan handed over the evidence bag and continued to work hard.

The director and the others stayed for a while, then went outside and spoke in a low voice.

Now the investigation, trace inspection and forensic doctors also left the scene one after another.

after sunset.

Together with another young police officer, Jiang Yuan carried the body to Iveco and brought it back to the funeral home.

Wu Jun also followed with the car.

The funeral home at night is eerie and terrifying.

The big dark pine tree looks strong during the day, but it is easy to make people think of many associations when viewed at night...

The old man at the door opened the door rubbing his eyes, pointed the way with a smirk, "Don't go to the left, there are many ghosts on the left."

The young police officer who came with him was all excited, and couldn't help but ask, "What's so important about this?"

The old gatekeeper said listlessly: "If you don't believe me, go to the left. I don't care."

"Go to the right." Wu Jun said solemnly.

The young police officer let go of the brakes and turned the steering wheel to the right, but he still couldn't help but said, "He opened the door for us at night, he's upset to scare us."

"Maybe." Wu Jun replied.

"Is there any other possibility?"

Wu Jun thought for a while and said, "Maybe it's the Bodhisattva's blessing?"

The little police officer was stunned for a long time before he realized what Wu Jun was talking about was a homophonic stalk, and he was speechless immediately.

The three of them worked together to reach the dissection room as quickly as possible.

When the bright white light flashed, the stainless steel autopsy table glowed with silver light, which was extraordinarily reassuring.

Wu Jun and Jiang Yuan were busy preparing for the autopsy.

In big cities, in some busy districts and counties, there may be queues for autopsies.But in places like Ningtai County, there are basically no folk autopsies, and there are few homicides and abnormal deaths, so you can work with peace of mind if you have a dead body.

As for things like staying up late, in the face of the sudden murder, everyone tensed up, and they were not the only ones who stayed up late and were about to stay up late.

Similar to the last autopsy, after asking the brother-in-law of the deceased who came later to sign, Wu Jun still asked Jiang Yuan to operate.

He had the idea of ​​letting Jiang Yuan practice. Of course, he couldn't straighten his back because of the exhaustion of the on-site exploration.

Watching Jiang Yuan pick up the scalpel, Wu Jun said: "We are forensic doctors, we cut corpses, and we pay attention to wide opening and closing. You can open it at ease, it doesn't matter if you move it a little bit."

Jiang Yuan nodded, first looked down at the corpse.

When the corpse was at the scene, although it was gradually cooling down, it still felt warm.

Now, when it was moved to the stainless steel dissection table, the human attributes of the corpse were greatly lost.

Jiang Yuan also felt a slight discomfort.

This was the second corpse he handled after working, and it was a completely unfamiliar corpse... In retrospect, Jiang Yuan felt that Uncle Seventeen's corpse was more intimate.

Jiang Yuan squeezed the knife tightly and pulled it from the neck of the corpse to the pubic symphysis in one breath.

The skin and flesh that appeared were red, white and yellow, and Jiang Yuan's emotions were instantly relieved a lot.

The brother-in-law of the deceased who came to be a witness could not do it. He glanced at it and his expression was wrong.

The little police officer who was still very energetic when he lifted the corpse just now also lowered his head, frowning tightly, unwilling to take a closer look.

Wu Jun handed a trash can to the brother-in-law of the deceased to prevent him from suddenly changing his face, and said: "Nowadays, people eat all day long and do not exercise. The body fat rate is high, and there is more fat..."

There seemed to be an element of apology in his tone, and the brother-in-law of the deceased's expression became even more distorted when he heard it.

Wu Jun shook his head, returned to the dissecting table, and said to Jiang Yuan, who was separated by a dead body, "I'm not good at comforting people either. It would be great if there was a female forensic doctor."

"Will female forensic doctors be more gentle?" When Jiang Yuan was studying, half of his classmates were women, but when they went to find a job, most of them chose to take the ordinary civil servant exam or interview for judicial appraisal institutes, and the rest were often the same. Make the forensic doctor of the procuratorate the first choice.

Wu Jun looked down at the incision of the deceased, helped Jiang Yuan to pull it, and said: "It must be better than me. It's just not used when lifting the corpse."

Jiang Yuan didn't care about talking, cut out the scalpel along the ribs, lifted the sternum, and then began to cut along the back of the sternum.

Unlike the doctor's cautiousness, the forensic doctor's movements are less particular, and the movements are bigger and more vigorous, so that in the silent dissection room, the sound of chopping flesh can be heard.

The victim's brother-in-law didn't dare to raise his head, wishing he could cover his ears.

"I can't take it anymore, so I'll just stay outside the autopsy room." Wu Jun couldn't force people to watch the autopsy, and he hated the smell of his family's vomit.

The victim's brother-in-law moved a few times, then froze again: "There is no one outside, I...I dare not..."

"You make your own decision." Wu Jun's attention was always on Jiang Yuan's side.

He started with Jiang Yuan, and he cooperated quite tacitly.

"A knife into the chest cavity. There are scratches on the ribs, so it should be very hard." Jiang Yuan opened the chest cavity, observed the situation inside, and made a judgment simultaneously.

Wu Jun nodded in agreement: "One knife is fatal. If it is slightly off, it may hit the ribs..."

Jiang Yuan confirmed the fatal injury, and waited for Wu Jun to take pictures, then turned over the opened chest muscles, found the skin wound on the other end, and continued to take pictures.

Then, Wu Jun handed Jiang Yuan a spoon and said, "Scoop out the blood in the chest cavity and weigh it."

Jiang Yuan then took an ordinary ceramic spoon, and scooped the accumulated blood in the chest cavity into a stainless steel basin little by little.

It is almost scooped clean, and then put the stainless steel basin on an electronic scale to weigh.The electronic scale is also non-specific. In other words, it is an ordinary electronic scale bought by Wu Jun from the market.The whole process, if the corpse is not considered, is actually a scene that ordinary people can completely accept.

"It looks like 850 milliliters. Plus the blood left in the room... How much blood will there be in the room?" Jiang Yuan turned to ask Wu Jun while making judgments.

"Less talk is so much." Wu Jun said based on experience.

Jiang Yuandao: "That adds up to 1700 milliliters, which is enough to cause death. The cause of death is that a sharp instrument punctured the aorta, resulting in massive blood loss and death?"

"Well." Wu Jun watched Jiang Yuan figure out the chest cavity, then pointed to the black spots on the corpse, and said, "Estimate the time of death?"

"About 8 hours to 10 hours? That's when he died around four or five in the afternoon?" Jiang Yuan pressed on the corpse spot, which faded but can be restored, indicating that the corpse spot has developed to the second stage of diffusion, combined with the body's corpse In the case of temperature, etc., a time judgment is given.

Determining the time of death is not easy.Like today's corpse, in a room at room temperature, the death time is short, and it is not too difficult to judge by various means.But if the death time is longer and the ambient temperature is more complicated, the judgment of death time becomes a science.

The police officer who came with him was a young man sent by the Second Squadron. Hearing Wu Jun's words, he quickly sent a message to the squadron leader.

"Remember to clarify the cause of death." Wu Jun reminded, and then said to Jiang Yuan: "Go on."

Jiang Yuan said "hmm", and continued to open the abdominal cavity without saying a word, and then dug out all the internal organs and weighed them.

After digging and digging, a shiny ball fell out of the kidney.

Jiang Yuan has touched the shiny dumpling once before.

Last time, what he got was Uncle Seventeen's legacy, LV3 special egg fried rice.

To be honest, Jiang Yuan thinks it is very practical. Even in his generation, people don't need to set up night stalls to make money, and occasionally cooking by themselves is a very good skill.

And this time...

Jiang Yuan touched the shiny dumpling lightly, and a system prompt flashed in front of his eyes:
Xue Ming's Legacy: Camping (LV2) - This is Xue Ming's favorite hobby, and also the activity he is best at.Whenever he drives a vehicle to a strange place, what Xue Ming wants to do most is to set up a tent and make a pot of ordinary tea.However, in most cases, driving is Xue Ming's job, and he can only imagine the comfort of camping in his mind.However, after changing positions, Xue Ming's chances of camping became less and less.The work that Xue Ming is best at is in order: using various tools to light fires, using various tools to judge the wind direction, using tampons to stop bleeding, using various tools to fetch water, using various tools to build tents...

Jiang Yuan smoothed Xue Ming's abdominal cavity with his hand, which was regarded as an expression of gratitude.

Turning his head, Jiang Yuan began to open the skull of the deceased.

In theory, forensic doctors do not need to perform a full autopsy on a corpse with a clear cause of death.Just like today's corpse, the cause of death has basically been determined, that is, the aorta was ruptured by a sharp instrument and died of blood loss.It is said that after the chest cavity is opened, at most the abdominal cavity can be opened to complete the task.

However, Jiang Yuan is still a rookie forensic doctor, and he always does things according to the norms.

Wu Jun also wanted him to exercise more, and would rather spend a few more hours with him.

After opening the cranial cavity, it was confirmed that there was no cerebral hemorrhage and no skull base injury, so there was no need to slice the brain like foie gras.

Even so, the two spent a lot of time. By the time they came out of the dissecting room, it was already daylight.

Hastily stepped over the brazier, and several squadrons also sent back news one after another-no progress.

Including the special hair in a special position that Jiang Yuan found, they couldn't find a match.

The atmosphere inside the Criminal Police Brigade suddenly became tense.
