This is a hideous wound so deep that the bone can be seen.
Compared to those so-called exposed broken bones and deformed skulls, it attracted the three people's attention more!
because.
The three people who are in the criminal investigation system are very clear about how bizarre and special it is to have a cut wrist wound on the fallen body!
At least.
Although Shen Lin has come into contact with hundreds of falling corpses over the years.
None of them had a similar situation.
......
He suppressed the astonishment in his eyes.
Shen Lin raised the deceased's left wrist, looked at it carefully, and frowned.
"This wrist cut was obviously not caused by the deceased himself."
"Because the wound is on the left wrist, according to the normal way of exerting force, if the knife is held in the right hand to cut, the cutting direction will definitely be..."
"From the outside to the inside, it is absolutely impossible to do it from the inside to the outside like we are doing now. This does not conform to the normal human body."
"Wrist cutting can cause this kind of special wound from the inside out. According to past experience, it is basically another person standing opposite, holding a sharp weapon and cutting, so the direction of the wound can be from the inside out!"
Shen Lin's words were truly 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 several times.
Whenever there are other people involved in a case, there is a possibility of homicide.
Xu Changsheng frowned slightly. As an experienced criminal policeman, he was very clear about...
There are two types of cases: campus homicide and campus suicide.
It seems that the case classification with only one word different can have a huge difference in impact and public opinion.
Then he took a deep breath and said calmly.
"Forensic Doctor Shen, please check carefully."
"Was the specific cause of death of this child due to excessive bleeding from cutting his wrists, or was it due to falling from a building?"
"Or does it exist..."
"Is it possible that he was forced to slit his wrists and then pretended to fall from a building?"
It's obvious.
If this case had the potential to be a homicide, the level of attention it would receive would be different.
The golden forty-eight hours are an important node that must be seized.
Before Shen Lin could answer.
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 is most likely to have committed suicide, and in my opinion..."
"This hideous cut on the wrist was most likely caused by someone else after the fall."
"First of all, why do you say it's suicide?"
"You can come and see the bloodstains from the fall. The distance from the teaching building is about two meters."
"Based on our criminal investigation experience."
"If the victim was pushed down the building, or thrown down after death, most of them would fall to their death within one meter of the building due to the weight."
"But if you jump down by yourself, because of inertia and the parabola, the basic distance from the building can be about 1.5 meters."
"But now..."
"The bloodstains of the deceased were about two meters away from the building, not 1.5 meters, let alone within one meter."
"This shows that the deceased probably used all his strength to jump backwards, with his arms open, to reach a distance of two meters."
"So we can basically confirm that the deceased jumped off the building on his own and was not pushed or left behind by anyone."
Speaking of this.
Su Ming stopped talking temporarily, and after searching on the ground for several seconds, 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 victim's wrist was extremely deep and had completely severed the radial artery, which meant that the amount of bleeding would be extremely large, and there was no possibility of spontaneous clotting."
"Based on the human body's tolerance, if a normal person's radial artery is cut, they will enter a state of near-hemorrhagic shock with weakness and dizziness within two minutes at most."
"And in this state."
"No normal person can climb up to the railing, let alone jump down from the building."
"certainly."
"There is a possibility that the deceased had his radial artery cut and he immediately climbed over the railing and jumped to his death without any psychological preparation."
"If that's the case, it's possible that the person jumped off the building before going into shock due to blood loss."
"But I think..."
"It would be difficult for a junior high school student to endure the pain of such a deep wound that could be seen through the bone, and to have the courage to jump off the building without any hesitation or mental preparation."
"To prevent this deceased person from being so extreme, he no longer has any attachment to the world."
"I just looked carefully and found that there were no blood drops 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 falling from the building, I think with the blood pressure in the artery, there would definitely be a lot of blood splashing in the air."
"But now... there is nothing at all!"
"This is sufficient to prove that shortly after the deceased fell from the building, or within a few minutes, someone came to her side and cut the radial artery in her left wrist in order to achieve..."
"One hundred percent death purpose!!!"
"Hiss." Xu Changsheng subconsciously took a breath of cold air and looked at Su Ming with disbelief and tingling scalp.
Although in the previous two cases.
Su Ming has demonstrated an extremely terrifying talent for reasoning and solving cases, but Xu Changsheng still hasn't gotten used to it and hasn't become completely numb.
Or rather.
Su Ming's mastery of criminal investigation knowledge.
as well as.
This ability to infer with almost 100% accuracy and restore a series of criminal processes based on only one detail clue is truly impossible to ignore, and it will amaze and shock people every time.
It's as if.
It seemed like Su Ming had experienced these cases personally, so they were not difficult at all.
As for Shen Lin, who was wearing rubber gloves, she glanced at Su Ming with trembling eyes and forced herself to suppress the urge to raise her glasses.
Without any hesitation, he immediately examined the body in more detail, especially the fatal wounds.
Xu Changsheng wisely did not speak, quietly waiting for Shen Lin's specific autopsy results.
The surroundings were quiet and a little depressing.
Three minutes later.
After Shen Lin finished a rough inspection, she looked at Su Ming with a complicated expression and nodded.
"Officer Su Ming is right."
"This wound on the wrist was indeed a secondary injury caused by someone else after the deceased fell from the building."
"I was able to come to this conclusion because of my rough autopsy just now."
"It can be roughly concluded that..."
"The deceased fell from the building on his back, the back of his skull was shattered, his limbs were fractured due to 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 injuries, it looks serious overall, but since the heart was not damaged, he may have still been breathing when he fell from the building, but he is definitely not the type that can be saved."
"at the same time."
"According to the analysis of the coagulation degree and range of each wound, the coagulation range of the radial artery in the wrist is obviously lower than that of the other injured parts."
"Since the total amount of blood in the human body is limited, if the bleeding cannot be stopped, the earlier the bleeding occurs, the larger the range of blood coagulation formed by platelets will naturally be."
"But now..."
"Compared to several major wounds, the radial artery obviously has a lower range and degree of coagulation."
"Plus, the deceased may not have been completely dead when he fell from the building."
"This undoubtedly proves that..."
Speaking of this.
Shen Lin paused for two seconds, looked directly into the eyes of Su Ming and Xu Changsheng, and said solemnly.
"Someone has to make sure she's 100% dead!!!"
