After 100,000 simulated crimes, I became an ace detective.

The murderer is a left-hander!

Su Ming's conclusion made Xu Changsheng stunned for a moment.

then.

Then he quickly stepped forward and looked at the screen, his face full of shock and confusion.

"No, Xiao Ming."

"How did you determine that the murderer was left-handed?"

"As for."

"Aren't the muscle textures and incisions of cooked corpses somewhat random? Can they also be used as clues to infer?"

It is clear.

Su Ming used the incisions and texture of the victim's body to determine the murderer's dominant hand.

at this point.

It was really beyond Xu Changsheng's understanding.

because.

in criminal investigation.

Judging the murder weapon and the direction of the attack through the victim's wounds is an existing technology and a commonly used technique in solving crimes.

but.

There is an obvious premise for this case of mutilation of corpses at Shanghai University.

That is.

The victim's body was cooked in advance and then cut into small pieces.

Xu Changsheng has never seen...

under these circumstances.

You can also determine the murderer's dominant hand through the texture and incisions!

......

Looking at Xu Changsheng's shocked expression.

Su Ming was not surprised at all, and had already expected it.

because.

Looking for clues through the muscles and textures of cooked corpses has long been beyond the capabilities of normal detectives.

In a real criminal investigation.

It is also extremely difficult, even impossible, to determine the murderer's dominant hand.

because.

When the murderer commits the crime, he basically does it naturally, as smoothly as he wants, and as he can achieve his goal.

Even if the murderer in a certain case is left-handed.

But in order to achieve the purpose of killing, it is very likely that when you see your right hand is relatively close to the murder weapon, under the influence of adrenaline, you will pick it up and attack the victim first.

Handedness is extremely difficult to determine because there are so many uncertainties.

Like a TV show.

It is completely impossible to determine the dominant hand just by looking at the wound.

If Su Ming had not used various killing methods in an attempt to meet the requirements of a perfect crime, he would not have noticed such details.

It is even less possible to be so confidently certain...

The murderer was left-handed.

now.

Su Ming pasted two different photos of the victim's body in front of the screen.

"Brother Sheng."

"Getting clues through muscle texture and incisions, although it sounds incredible, let me explain it a little bit..."

"You will know why I came to this conclusion."

Speaking of it.

Without any hesitation, Su Ming pointed at the photo of the victim's body above.

this picture.

It was the first bag of body parts found by the victim, the bag that the sanitation workers took away as cooked beef and almost consumed.

"Brother Sheng, please observe carefully."

"In this picture of the victim's body, the muscle texture is obviously darker on the right and lighter on the left, and the incision is also clearer on the right."

"You can picture it in your head."

"At this time, a large piece of meat is placed on the chopping board. When a normal person cuts the meat, he will definitely exert more force at first, because there is no need to worry about the kitchen knife hitting the chopping board."

"When you cut to the last point, you will subconsciously stop the sound to avoid making the sound too loud."

"This is everyone's inertia, or subconscious behavior, and if you are in the murderer's environment, you will definitely pay more attention to the volume of the sound."

"Such a force-generating and force-receiving method will result in the area where the force is greater, the texture and incisions will be clearer and more obvious than the area where the force is retracted."

"When the murderer dismembered the victim's body, he was actually more careful than we normally cut the meat. This will definitely lead to the uneven use of force."

"Now the body parts in the picture."

"The texture and incisions on the right side are obviously clearer than those on the left side. According to a normal person's meat-cutting posture, there is no doubt that the right hand is holding the knife for cutting."

"This information means..."

"When cutting the victim's body, the murderer held the knife in his right hand."

This explanation from shallow to deep.

Xu Changsheng secretly took a breath of cold air. He placed his right hand horizontally and raised his head in the shape of a knife, cutting downwards in the void to feel the change in power.

result.

Just as Su Ming said.

Once you feel that you are about to touch the cutting board, you will subconsciously reduce your strength. This is the inertia of the human body that is difficult to overcome! ! !

After making sure this clue can be verified.

Xu Changsheng sipped the Yahuazi vigorously, put down the wolfberry water in his hand, and frowned even more.

"Xiao Ming, your method of judging handedness through texture and incision..."

"I can roughly agree with it nine points."

"But I feel that the scope of application of this criminal investigation technology is also very narrow. After all, there are not many criminal suspects who can be like the murderer of the Mordu Corpse Case."

"By cooking and dismembering the body so calmly, most of the people would not be able to dispose of the body in time, but here it is possible to determine the dominant hand."

"but."

"It's very strange. Judging from this detail..."

"The murderer's dominant hand should be his right hand, not his left. How did Xiao Ming get the clue that he was left-handed?"

Although the scope of application of this criminal investigation technology is very narrow.

But now something has actually been gained, and key clues have been found from those photos of corpses from twenty years ago! ! !

Xu Changsheng had to admit that Su Ming's talent in solving crimes was truly astonishing and terrifying.

After so many years as a criminal police officer, he had never thought...

It's actually possible to determine each person's dominant hand based on the strength of cutting meat.

But he was also becoming more and more confused.

It was obvious that the body parts could be used to determine that the dominant hand was the right hand, but why was Su Ming so sure that the murderer was left-handed?

Xu Changsheng did not wonder for too long.

Su Ming pointed to the photo of the corpse below.

this picture.

It was a photo of the victim's cooked head. The multi-angle display looked particularly hideous and terrifying, enough to give ordinary people nightmares.

"Brother Sheng, look carefully at the cutout on the neck."

"You should be able to see very clearly based on our previous skills in judging the cutting direction of corpses..."

"On both sides of the cervical vertebrae of the neck, it is obvious that one side has more obvious muscle texture, while the other side is a bit blurry and unclear."

"But the directions of the corpses are different from those before."

"The muscle texture on the neck is more obvious on the left side, while the right side is the result of the murderer obviously reducing his strength."

"Here we can conclude that the murderer held a knife in his left hand and divided the victim's body and head. Now there are two completely different answers."

"The murderer used his right hand to hold the knife when cutting up the body parts, and when cutting the head, he used his left hand to hold the knife."

“It may seem difficult to tell, but it only takes a little thought to figure out the answer.”

"Because the body parts are purely made of muscle, the murderer does not need to use special force. When cutting the head, because of the existence of the bones of the spine..."

"The murderer must exert more force!!!"

now.

There was no need for Su Ming to continue explaining.

Xu Changsheng suddenly slapped his thigh and said excitedly with sudden realization.

"When cutting hard objects and lifting heavy objects."

"It's inevitable that everyone subconsciously uses their dominant hand to provide more power."

"So by comparing the two things of cutting the corpse into pieces and cutting off the neck bones, we can draw a very clear conclusion..."

"The murderer is left-handed, so he uses the knife in his left hand to chop bones."

"The reason why he cut the body into pieces with a knife in his right hand was actually a deliberate cover-up to confuse the police and remove their suspicion!"

"But why do you deliberately hide your left-handedness?"

"Although the number of left-handers among ordinary people is relatively small, it should not be to the point where it is necessary to deliberately hide it, unless it is..."

Speaking of it.

Xu Changsheng paused for two seconds, looked at Su Ming and said with gleaming eyes.

"unless......"

“The murderer’s occupation is somewhat special, and with the trait of being left-handed, it’s easy to find him!!!”
