Su Ming's speculation.
This made Xu Changsheng and Lin Tian a little confused, and even indescribably surprised.
Because they don't know.
Where on earth could Su Ming conclude that the murderer of the dismemberment case at Modu University mostly used the hammer-style grip that was convenient for exerting force.
It also completely excludes the two common ways of holding a knife by doctors: holding a bow and holding a pen.
Of course the most important thing is...
The hammer grip is usually used for hammering and chopping, which are large-scale and meticulous tasks.
But now.
From this recorded video.
The murderer of this dismemberment case should be quite meticulous and have outstanding knife skills.
Otherwise.
How is it possible that when dismembering a victim, even the size and shape of the body parts are almost the same?
But the hammer grip basically makes it impossible to practice sword skills.
after all.
Has anyone ever seen someone practicing fine knife skills using the rough gesture of holding a hammer?
......
It seemed that he could see the current confusion of Lin Tian and Xu Changsheng.
Su Ming did not hesitate at all. He picked up the remote control on the table and chose to replay the video recording of the murderer dismembering a body.
The slightly horrifying bloody hand scene appeared again when the murderer revealed his bloody palm and was about to show the victim's head from all angles.
Su Ming immediately pressed the pause button and greatly enlarged the blood stain on the murderer's palm.
Immediately following.
Su Ming strode directly to the front of the screen, pointed at the bloodstains of varying depths on the top of the murderer's left palm, squinted his eyes and inferred aloud.
"Director Lin, Brother Sheng."
"First, we have previously determined through the body parts and the location of the skull fracture that the murderer is left-handed."
"So when picking up heavy objects or wielding tools in daily life, the murderer must have habitually used his left hand."
"Plus."
"The protruding finger joints of the murderer, as well as the numerous healed and recently inflicted cuts on his side, indicate that he had been working or training for a long time."
"Now."
"Look carefully at the bloodstains on the top of the murderer's left palm. Can you see the extremely hidden fractures of varying depths?"
"This is obviously different from the evenly distributed bloodstain in the center."
Hearing this.
Xu Changsheng frowned immediately, thought very seriously for a few seconds, then shook his head with a little confusion.
"Xiao Ming, what can these bloodstains of varying depths indicate?"
"No matter how you look at it, this is a very accidental thing. I don't think it can be used as a clue or source of evidence."
"Just like the murderer's palms would be different depths if he pressed his hands deeper or shallower into the pool of blood..."
Before Xu Changsheng could finish speaking.
Lin Tian simply knocked on the table, interrupting his subsequent words, and explained uncertainly.
"No, Sheng."
"Look at the bloodstains evenly distributed on the murderer's palm. This means that his entire hand must have been pressed into a pool of blood."
"But there are bloodstains of varying depths on the palms, and Xiao Ming just specifically suggested the hammer grip method, which is more convenient for exerting force."
"Think about it for a moment."
"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 is needed to fix it and prevent it from slipping out of the hand?"
"That's why."
"When doing high-intensity training and wielding tools, the top of the palm will definitely be worn and healed repeatedly, eventually forming prominent calluses."
"For doctors and forensic doctors, there is no need to use a hammer grip, let alone develop calluses on the palms."
"but."
"From the carefulness with which the murderer cut up the body, and the familiarity of his technique, it can be seen that."
"I'm afraid this murderer is..."
"In daily work or practice, not only is it necessary to use a hammer grip to exert force, but it also requires very fine cutting and decomposition."
"If these two points are met, the relevant professions I can think of at the moment are..."
"Butcher, chef, duck filleter, tuna cutter, etc. But something's not right."
Speaking of this.
Lin Tian suddenly overturned his previous guess, frowned, sniffed the tobacco on his index finger, and spoke slowly.
"Based on the content of the post on the dark web."
"From the details we deduced yesterday, the murderer must have a high social status, and his fame and wealth must also be among the best."
"And judging from the state of the recorded video, the murderer's hands must 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 most important thing is..."
"There is no particularly obvious difference in status between these professions and college students, and it cannot reach the level described in that post."
"It is difficult for us, the police and the public, to associate this case with this."
at the same time.
Xu Changsheng also figured out the depth of the bloodstain on the murderer's palm, and then followed Lin Tian's words.
"Master, there is more to it than that."
"If you're a common profession like a chef or a butcher, there shouldn't be any need to hide your left-handedness."
"after all."
"There are quite a few people working in these professions. A left-handed person alone can't lock onto anything, let alone go to great lengths to hide."
“And I remember there was a sentence like this in that post.”
"If you want to avoid suspicion to the greatest extent, the best way is to let the prey come to you and cover up all your tracks yourself."
"I don't think a career like butchering would be attractive to a college student, not to mention having to cover up one's actions."
"So the murderer's profession must be very special and attractive to college students."
This moment.
The entire conference room fell silent.
Su Ming and the other two began to think seriously about what kind of profession could meet so many requirements.
Eat with your hands.
Cuts on fingers are common.
The need to hold tools tightly for long periods of time and hammer or cut hard causes calluses to form on the tops of your palms.
They are also good at fine segmentation work and can cut corpses into pieces of almost the same size and shape.
The overall number of practitioners 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 this profession and college students, and it is a profession that is difficult to associate with under normal circumstances.
Judging from the way the victim's body parts were cut, he should have a good understanding of human joint tissue.
......
The three of them kept thinking.
The recorded video on the screen was still playing. Su Ming leaned comfortably in the chair, tapping the back of his left hand with his right index finger, squinting his eyes and emptying his mind.
My mind is constantly screening what profession can meet so many requirements.
And at this moment.
The only words of the murderer in the dismemberment video slowly entered Su Ming's empty mind.
"It's actually more worrying and nostalgic than the golden cut rate of 0.618."
"This is truly perfect...truly perfect work!"
