The body was transported away, and Professor Chen wanted to leave with the body.

He was doing an anatomy, essentially dealing with corpses, and the crime scene was not considered his business scope.

Jiang Yuan was reluctant to see the temporary skill he had just used and said, "I want to take a look again. It's been a long time since I saw the front-line scene. I'll wait until I'm back, and I have to look at the photos again."

In more than 500 minutes, the skill will be improved by 1 point, and the understanding of the skill of case and crime scene reconstruction will be improved.

"Uh... OK." Professor Chen was a little embarrassed, so he stayed there too.

The smell on the scene was strong, not only the smell of blood, but also the smell of the kitchen and restaurant that had not been cleaned up, but also kept floating in.

The weak light in the restaurant was replaced by a few bright headlights. The headlights were pure white and blazing like a middle-aged man with oysters covered in crotch, trying to play the greatest role in a limited time.

Jiang Yuan was calculating and observing the scene.

Compared to looking at photos, the smell on the scene is also one of the basis for judgment. In addition, it is difficult to observe from photos such as semi-dry blood stains, its coagulation degree, or the softness of the blood that is forming a beach.

Observing the time of death through blood is actually a very mature technique, and multiple indicators in multiple dimensions can be used for judgment.

Similar to bloodstain analysis, many old detectives have expertise in this area, but they are better than old scholars like Professor Chen.

In the early years, when encountering murder cases or blood-stained robberies, old detectives often need to be accurate to the death time of hours.

In the era of many cases, there is actually no need to practice. After catching the murderer for interrogation, confirming the time of death, then checking the blood stains on the scene in reverse. Using this method, you will soon become familiar with the relationship between the blood stains and the time of death. This can even be called the part where practice makes perfect.

Nowadays, there are more methods of handling cases, and blood is less valuable. The most special significance of the reconstruction of the crime scene has been transferred to the camera, and some have been slowly forgotten.

Jiang Yuan looked at the scene and simulated the scene in his mind.

Since the blood stains under the body were confirmed, the scene in Jiang Yuan's mind has become more complete.

Based on recent experience in doing cases, Jiang Yuan was not humble in this regard. After confirming, he said directly: "I will conduct an analysis of on-site reconstruction. Can you have a basic concept to facilitate the investigation of the case later?"

"Okay." When Huang Qiangmin was selling Jiang Yuan in other cities and counties, he saw Jiang Yuan performing similar performances. At that time, he wanted Ningtai County and had such an opportunity.

Before, there were mainly no suitable cases in the country. This time, Jiang Yuan took the initiative to raise them, and Huang Qiangmin seemed a little happy.

Other criminal police officers who had seen and had never seen each other came over.

Someone asked: "Can you record the video?"

"Yes. And you have to record videos. Two people will tag and take photos so that the information will be clearer when looking back." Jiang Yuan replied, stood a few meters away from the body, and said, "I'm starting, this is the starting point of the conflict. Mark it."

A policeman took the yellow and white label of No. 101 and put it at the place where Jiang Yuan pointed, and the technician of the Criminal Department next to him came to take a photo and recorded it. At the same time, the camera next to him continued to take a video without pause.

All samples have been taken at the scene. Jiang Yuan took two steps back and said:

"The victim and the perpetrator No. 1 should have had a sudden conflict. At the beginning, both sides may have some restraint, damaging some tables, chairs, and benches. The personal injury cannot be determined."

"As the perpetrator No. 1 lost control, he suddenly increased his strength in the conflict, causing the victim to hit the wall."

"The victim fell softly on the spot. At this time, the perpetrator No. 1 came forward to check, and the first drag was formed. Because the victim's bleeding was not that large, the blood stains left behind were not so obvious."

When Professor Chen heard this, he couldn't help but look forward and said directly: "I didn't notice that there were still blood stains here just now."

Jiang Yuan nodded, leaned over and asked to take a photo, and then said: "Later, the wiped blood was equivalent to being covered by a pool of blood, but because the pool of blood was formed relatively late, you can make some judgment."

Professor Chen looked carefully and nodded slowly. Although he had been away from the front line for a long time, Professor Chen knew in his heart that even if his condition was at its peak, it would not be easy to discover this.

The pool of blood is more than an hour later than the wipe marks, which shows different depths on the blood stains. This alone can already explain many problems.

Jiang Yuan said at this time: "Actually, looking closely, the pool of blood was formed twice."

Professor Chen was shocked. He had been a teacher for too long and habitually refuted: "You can't derive evidence from the results. There is no need to make this judgment. Even if it is a pool of blood formed by two pools of blood, it is difficult for you to say that they were formed twice."

Jiang Yuan did smile and said, "I judged it from insects."

"kindness?"

"When the first small pool of blood was formed, there were insects like ants and wade into muddy water." Jiang Yuan described it a little, then squatted in front of the pool of blood, looked at it again with a horseshoe mirror, and said, "These tiny scratches are actually left by ants and insects who are wooing over. Then they were covered by the blood later."

Professor Chen looked hard for a while and said helplessly: "I am old and my eyes can't be able to see clearly."

He did not fully admit it, but he could not deny Jiang Yuan's point of view.

Jiang Yuan is no longer a student in the school, and he doesn't need to be recognized by Professor Chen. He then took a few more steps and said: "This is likely to be the route for No. 1 perpetrator to escape."

Because the perpetrator of No. 1 is currently a mentally ill, this roadmap is not easy to be verified.

Jiang Yuan didn't say much about this. Strictly speaking, Han Shengyan, who had surrendered himself, is no longer a problem. Unless he has never done it, he is mentally ill and is talking nonsense, otherwise, the part of the person in charge of Han Shengyan does not need much evidence to support it.

Moreover, considering that most of the outside of the restaurant is hardened, some shops also have external cameras, etc. If you look back and carefully, you should be able to find Han Shengyan's figure - mentally ill patients will definitely not engage in too many anti-reconnaissance flower heads.

"Where is the second perpetrator?" Liu Wenkai from the second squadron was excited and anxious to know the follow-up.

Jiang Yuan walked back to the opposite side of the original corpse and said, "If the perpetrator of No. 2, he should have been here about an hour and a half after No. 1."

Jiang Yuan carefully walked forward two steps, made a simulated bend, put his hand forward, and said, "This is the place where the second drag appears. At this time, the victim did not have much blood. You can see it by looking at the blood marks on the wipe."

"The second perpetrator checked the victim's situation at this time. He is likely to have a conversation with the victim, at least the victim was alive at the time, otherwise there would be no need to attack again."

"The victim was traumatized again in the back of his head."

...

Jiang Yuan explained several detailed points in detail, and then directed the technician to take samples again, so that the on-site survey was truly completed.

Everyone went home, and the criminal department personnel processed the evidence. The criminal police attacked everywhere and began to touch the victim's interpersonal relationships to investigate.

Professor Chen and Jiang Yuan rushed to the funeral home every night and dissected the body.

The main examination is the wound behind the victim's head.

Together, the two of them quickly peeled off the scalp of the body with the cheers of the incense ignited by Wu Jun.

First look at the scalp, you can see the rectangular centrally controlled contusions and some epidermal peeling.

The lifted scalp is very thin, the thickness and feel are similar to the leather wallet, which is a little smooth and has a certain degree of toughness after soaking with a little saline. Doing so will help sew the body backwards.

In addition, there are some debris near the scalp, which are collected and left to be inspected.

"It was indeed multiple hits." Jiang Yuan scraped the skull and gave a positive conclusion.

This time, Professor Chen became more confident and said, "And they were all flat hits. If you look at the position like this, the second murderer may have lifted the victim's head and hit him hard."
