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

Su Ming's speculation.

This made Xu Changsheng and Lin Tianlue a little confused, and even more surprised.

Because they don't know.

How could Su Ming figure out that the murderer of the case of dismemberment of corpses in Shanghai University of Science and Technology mostly used the hammer-style grip, which is convenient for exerting force.

Furthermore, the two common ways doctors hold a knife, holding a bow and holding a pen, are completely excluded.

Of course the most important thing is...

The hammer grip is usually used for percussion and chop, which is a kind of broad and undetailed thing.

But now.

Judging from this recorded video.

The murderer of this corpse dismemberment case must be quite meticulous and have outstanding knife skills.

if not.

How is it possible that when dismembering a victim, even the size and shape of the body parts are almost the same.

But with the hammer grip, you can basically not practice knife skills.

after all.

Has anyone seen someone practice fine knife skills using the crude gesture of holding a hammer?

......

It seems that they can see the current doubts of Lin Tian and Xu Changsheng.

Without any hesitation, Su Ming immediately picked up the remote control on the table and chose to replay the video of the murderer's dismemberment.

The slightly horrifying scene of bloody hands appears again, when the murderer reveals his blood-stained palms and prepares to show the victim's head from all angles.

Su Ming immediately pressed the pause button, which greatly magnified the blood stain on the murderer's palm.

Followed by.

Su Ming took the lead and strode to the screen, pointed at the varying shades of blood on the top of the murderer's left hand, squinted his eyes and deduced aloud.

"Lin Bureau, Brother Sheng."

"First of all, we previously determined through the body parts of the deceased and the location of the skull fracture that the murderer was a left-handed man."

"So when picking up heavy objects or wielding tools in daily life, the murderer must habitually use his left hand."

"Plus."

"The protruding finger joints from the murderer, as well as the numerous healed and recently inflicted cuts on the sides, indicate that the length of time he worked or trained was not low."

"Now."

"If you carefully observe the blood stain on the top of the palm of the murderer's left hand, can you see an extremely hidden sense of fracture in different shades?"

"This is obviously different from the uniform blood stain in the center."

Hear this.

Xu Changsheng frowned immediately, and after thinking extremely seriously for a few seconds, he shook his head and said with some confusion.

"Xiao Ming, can this kind of blood stains of different shades mean anything?"

"No matter how you look at it, this is a very accidental thing. I feel that it cannot be used as a source of inference as clues or evidence."

"Just like if the murderer presses lightly or deeply into a pool of blood, it will cause blood stains on his palms to vary in depth..."

Before Xu Changsheng could finish speaking.

Lin Tian then knocked on the table, interrupted his subsequent words, and explained uncertainly.

"No, Asheng."

"Look at the even blood stains on the murderer's palm, which means his entire hand should have been buried in a pool of blood."

"But there are bloodstains of different shades on the palm of the hand. In addition, Xiao Ming just proposed a hammer-style grip that is easier to use."

"Think about it."

"Does the hammer grip require the entire palm to be tightly attached to the wooden handle of the tool, especially the top of the palm, which needs to be fixed to prevent it from falling out of the hand."

"Therefore."

"When you perform high-intensity training and wield tools, you will definitely wear and heal the top of the palm many times, eventually forming prominent calluses."

"And for professions such as doctors or forensics, there is no need to use a hammer-style grip that is convenient for exerting force, let alone grinding out calluses on the palms."

"but."

"Judging from the degree of care with which the murderer cut up the body, and the way he used it, he was not unfamiliar with it."

"I'm afraid this murderer is..."

"In daily work or practice, not only do you need to use the hammer grip to generate force, but you also need quite precise cutting and decomposition."

"If these two points are to be met, the relevant professions I can think of at present are..."

"The butcher, the cook, the duck filleter, the tuna cutter, etc., but there's something not quite right."

Speaking of it.

Lin Tian suddenly overturned his previous guess, frowned and sniffed the smell of tobacco on his index finger, and said slowly.

"Based on content of posts on the dark web."

"From the details we deduced yesterday, the murderer should have a high social status, and his reputation and money should also be among the best."

"And judging from the state in the recorded video, the murderer's hands should have been specially maintained in various ways, but for professions like chefs and butchers, there is no need to maintain their hands at all."

"The key is......"

"There is no particularly obvious status gap between these professionals and college students, and they cannot achieve what was said in that post."

"It is hard for us, the police and the public, to think that it is related to this case."

at the same time.

Xu Changsheng also figured out the problem of the depth of blood on the murderer's palm, and then followed Lin Tian's words.

"Master, it's more than that."

"If it were a common profession like chef or butcher, there should be no need to hide one's left-handedness."

"after all."

"There are not many people working in these professions. Just a left-handed person can't target anything at all, and there is no need to spend great efforts to hide it."

"And I remember there was this sentence in that post."

"The best way to avoid suspicion to the greatest extent is to let the prey find itself and cover up all the tracks yourself."

"I think a profession like butcher would hardly be attractive to a college student, let alone having to cover up his actions."

"So the murderer's profession should be very special and attractive to college students."

this moment.

The entire conference room fell silent.

Su Ming and the three of them began to think carefully about what kind of profession could meet so many requirements.

Eat with your hands.

Fingers often have cuts.

The need to hold the tool tightly for long periods of time and hammer or cut with force results in calluses on the top of the palm.

He is also good at fine segmentation work and can cut corpses into almost the same size and shape.

The overall number of employees is small, the economic conditions are excellent, and it has a certain appeal or value to college students.

There is a huge gap in social status between college students and students, and it is a career that is difficult to think of under normal circumstances.

Judging from the cutting conditions of the victim's body, he should have a good understanding of human joint tissue and so on.

......

The three of them kept thinking.

The recorded video on the screen was still playing continuously. Su Ming leaned back on the chair comfortably, tapping the back of his left hand with his right index finger, squinting his eyes slightly and letting himself go.

My mind is constantly sifting through what kind of profession can meet so many requirements.

And right now.

The murderer's only words in the dismemberment video slowly entered Su Ming's empty mind.

"It actually makes people more anxious and nostalgic than the golden cutting rate of 0.618."

"This is truly perfect...truly perfect work!"
