Chapter 26 Someone wants to make sure she dies 100%!!!

This hideous wound that was so deep that the bone could be seen.

Compared to those so-called exposed broken bones and deformed skulls, it attracted the three people's attention even more!

Because.

The three people in the criminal investigation system knew very well how bizarre and special it was to have a wrist cut on a fallen body!

At least.

Although Shen Lin had come into contact with hundreds of fallen bodies in these years.

None of them had a similar situation.

......

Contain the astonishment in his eyes.

Shen Lin raised the left wrist of the deceased, took a closer look, and frowned.

"This wrist cut was obviously not caused by the deceased himself."

"Because the wound is located on the left wrist, according to the normal way of exerting force, if the right hand is holding the knife to cut, the cutting direction must be..."

"From the outside to the inside, it is absolutely impossible to be from the inside to the outside like now, which does not conform to the human body's normal routine."

"Wrist cuts can cause this special wound from the inside to the outside. According to past experience, it is basically another person standing opposite, holding a sharp weapon to cut, and the direction of the wound can be from the inside to the outside!"

Shen Lin's words are shocking.

Because.

According to this speculation, in addition to the deceased himself, there are other people involved in this case! ! !

This factor undoubtedly increases the uncertainty and severity of the case by several times.

As long as there are other people in the case, there is a possibility of homicide.

Xu Changsheng frowned slightly. As an experienced criminal policeman, he is naturally very clear...

Campus homicide and campus suicide.

It seems that there is only one word different in the classification of cases. How big is the difference in impact and public opinion.

Then he took a deep breath and said calmly.

"Forensic Doctor Shen, please check carefully."

"The specific cause of death of this child, is it due to excessive bleeding from wrist cutting, or falling to death?"

"Or is there a possibility..."

"The possibility of being forced to cut wrists and finally pretending to fall to death?"

It is obvious.

If this case is likely to constitute a homicide, then the degree of attention will be different.

The golden forty-eight hours is an important node that must be seized.

Before Shen Lin answered.

Su Ming, who was standing next to him, carefully observed the bloodstains on the ground, then looked up at the height and distance of the abandoned teaching building, and answered slowly.

"Brother Sheng."

"The deceased should most likely have committed suicide, and in my opinion..."

"This hideous cut on the wrist was most likely cut by someone else after falling from the building."

"First of all, why do you say it was suicide?"

"You can take a look at the bloodstains from falling from the building. The distance from the teaching building is about two meters."

"According to our criminal investigation experience."

"If the victim was pushed down the building, or thrown down the building after death, due to the weight, most of them would fall to death within one meter of the building."

"But if they jumped down by themselves, because of inertia and parabolas, the basic distance from the building can be about one and a half meters."

"But now..."

"The distance between the bloodstains of the deceased and the building is about two meters, not one and a half meters, let alone one meter."

"This shows that the deceased most likely used all his strength to jump back, and his hands were in an open embrace, so that the traces of falling from the building could be two meters away."

"So it can be basically confirmed that the deceased jumped down by himself, not pushed or thrown down by others."

Speaking of this.

Su Ming paused for a moment, and after searching for several seconds on the ground, he did not find the scattered blood drops he wanted to see, so he shook his head and continued.

"As for why I said that the wound on the wrist was most likely caused by someone else after the fall."

"This is because..."

"The wound on the wrist of the deceased is very deep, and the radial artery has been completely cut, which means that the amount of bleeding will be extremely large, and there is no possibility of self-clotting."

"Based on the human body's tolerance, a normal person who cuts the radial artery will enter a state of near-hemorrhagic shock with weakness and dizziness in two minutes at most."

"And in this state."

"A normal person can't climb up the railing at all, let alone jump down from the building."

"Of course."

"There is also a possibility that the deceased did not need any psychological preparation immediately after the radial artery was cut, and he climbed up the railing and jumped off the building and died . "

"If so, it is indeed possible that the person jumped off the building before the blood loss and shock. "

"But I think..."

"It is probably difficult for a junior high school student to endure the pain caused by this deep wound that can be seen to the bone, and to have the courage to jump off the building without any hesitation or psychological preparation. "

"In order to prevent this deceased person from being so extreme, he has no attachment to the world. "

"I just looked carefully and found that there were no blood drops with a high degree of splashing on the ground near the traces of the fall. I didn't even see a single drop of blood. "

"If the radial artery was cut before the fall, I think with the blood pressure of the artery, there would definitely be a lot of blood drops splashing in the air. "

"But now... there is nothing at all! "

"This is enough to prove that shortly after the deceased fell, or within a few minutes, a person came to her side and cut the radial artery on her left wrist in order to..."

"The purpose of 100% death!!!"

"Hiss." Xu Changsheng took a deep breath subconsciously and looked at Su Ming with his scalp numb in disbelief.

Although in the previous two cases.

Su Ming has shown extremely terrifying talent for reasoning and solving crimes, but Xu Changsheng is still not used to it and is not completely numb yet.

Or rather.

Su Ming's mastery of criminal investigation knowledge.

as well as.

This ability to infer almost 100% and restore a series of criminal processes with just one detailed clue is really impossible to ignore, and you will be amazed and shocked every time.

Just as if.

Su Ming had experienced these cases personally before, so there was no difficulty at all.

Shen Lin, who was wearing rubber gloves, glanced at Su Ming with trembling eyes and suppressed her habit of raising her glasses.

Without any hesitation, he immediately examined the body in more detail, especially the fatal injuries.

Xu Changsheng wisely said nothing and quietly waited for Shen Lin's detailed autopsy results.

The surroundings were quiet and depressing.

Three minutes later.

After Shen Lin completed a rough inspection, she looked at Su Ming with a complicated look and nodded.

"Officer Su Ming is right."

"The wound on the wrist is indeed a secondary injury caused by others after the deceased fell from the building."

"The reason why I came to this conclusion is because of my rough autopsy just now."

"It can be roughly concluded..."

"The deceased fell from the building while lying on his back. The back of his head and skull were shattered. His limbs were fractured due to the force of the impact. His spine was broken into five sections. Three ribs were broken and fractured, one of which was inserted into his lung."

"Judging from the severity of the injury, it looks very serious overall. However, since the heart was not damaged, he may still be breathing when he fell, but he must be unable to be saved."

"at the same time."

"According to the analysis of the degree and range of coagulation in each wound, the coagulation range of the radial artery in the wrist is obviously lower than that of other injured parts."

"Since the total amount of blood in the human body is limited, if it cannot be stopped, the earlier the bleeding occurs, the wider the coagulation range formed by platelets will naturally be."

"But now..."

"Compared with several major wounds, the scope and degree of coagulation in the radial artery are obviously lower."

"In addition, the deceased may not have died completely when he first fell."

"This proves beyond a doubt..."

Speaking of which.

Shen Lin paused for two seconds, looked directly into the eyes of Su Ming and Xu Changsheng, and said solemnly.

"Someone is going to make sure she is 100% dead!!!"
