"Ye Fan, you just said, you have a question, what is it?" After thinking for a while, Xia Dong turned his head and asked Ye Fandao.

Everyone's eyes were on her, and Su Liang's eyes lit up even more, expecting that she would find something he hadn't noticed again, which would allow him to further improve this bloodstain spatter simulation.

"That's right, Ye Fan, is there something missing from my simulation data, or is it wrong. ”

"I very much agree with the simulation made by Brother Su, although the consistency is not 100%, or even less than 90%, but the comparison of the two maps can prove that the deceased was lying on his back when he died, not standing, so the stain on the clothes may be completely ruled out because he was pressed against the colored wall or mural while standing. ”

Ye Fan held the pen in his hand, lit the simulated picture in the air, his eyes were focused and serious, and his voice was serious: "But, Brother Su, you forget a little, the palm print I imprinted from the deceased's right thigh." ”

Su Liang's expression shook suddenly, only to hear Ye Fan ask again: "Brother Su, have you tested that palm print?"

"Qian Qian. Su Liang looked at Qian Qian, he was in charge of several of the most important testing experiments, Qian Qian was his assistant, responsible for some relatively detailed technical testing work, and the palm print from the deceased's thigh was his responsibility.

Qian Qian nodded, pulled the notebook from the side, clicked a few times, and the projection cloth was replaced with a palm-shaped photo of Ye Fan printed on the deceased's thigh with a fresh-keeping bag and depicted on the reverse side with a pen, as well as the palm print test report made by Qian Qian.

"I did get a set of fingerprints on the fresh-keeping bag, but because the fresh-keeping bag is not sticky, although Ye Fan did it very carefully, the fingerprints printed were finely broken and unformed, and could not be identified. Qian Qian said with some disappointment.

"There is no way to do it, the environment at that time ...... Ye Fan, you have done a good job. Afraid that Ye Fan would blame himself for being lost, the Chang team hurriedly comforted.

Ye Fan would not be so glassy, she had long expected that without professional tools, the collection and retention of physical evidence could not be completely undamaged.

"It's okay, although you can't get a complete fingerprint, but it's not without gains, at least it proves that the murderer didn't wear gloves when he committed the murder, and he only put on gloves when he pretended to carry the corpse and threw the corpse after the killing......" Speaking of this, something flashed in Ye Fan's mind, but unfortunately it flashed too fast and didn't catch it.

had to put it aside for a while and continued: "And what I want to say is not the question of fingerprints, but the circumstances under which the murderer grabbed the deceased's thigh. ”

"Ahem, cough ......" There was a coughing sound at the scene, although they told themselves that they were okay, but the male compatriots couldn't help but cough and blush.

Su Liang, a technical nerd, had the purest mind, and slapped his palm and said, "I understand, I understand what I missed in this analog figure." ”

He put the simulation out again, pointed a projection pen on the female model's hanging right leg and said: "At that time, the posture of the two people, the murderer should have grabbed her thigh like this, and forced, so the deceased's legs were cocked, and the curl of the skirt was also different. ”

"Yes, a slight difference can make a big difference. ”

Ye Fan nodded and said the image in his mind: "At the time of the crime, the murderer put the deceased on the ground, or on the table, grabbed her thigh with his right hand, and her skirt was rolled up. ”

As she spoke, her brow furrowed, and she said, "It's just that something is wrong here. ”

With Ye Fan's words, combined with the simulation map, everyone also has a specific image in their minds, but it is a little unsightly, and then look at the little girl, the gaze is pure and serious, which makes their minds too obscene.

"What's wrong?" asked Su Liang.

"At that time, if this was the case, the murderer was holding the deceased's thigh with his right hand, then he was holding the murder weapon with his left hand......"

"The murderer is a left-hander?"

"Possibly, but my doubt is that even if this person is left-handed, and in that environment, he can cut off a person's head with one hand, then this person's strength is somewhat beyond the range of ordinary people. Ye Fan's fingers lightly clasped the tabletop and groaned.

The human body is both fragile and hard, even if it is a butcher who kills pigs and chops bones all the year round, and the executioner who cut off the head in ancient times, they want to cut off a person's head cleanly, but also need to hold the knife in both hands, and use the strength of the whole body, which has to be those who have amazing strength and professional techniques to do it, many of them can't be cut down with a knife, and they have to cut a few more times.

And whether it is a butcher or an executioner, the bone chopping knife and execution knife used are thick and sharp.

According to the previous speculation on the scene of the first crime, it should be in or near a public area, how did the murderer take the weapon with him without being noticed, and take 10,000 steps back, the murderer was able to bring such a murder weapon with him for unknown reasons without arousing suspicion.

But she deduced before that the murderer did not premeditate murder, if it was such a murder weapon, then, where could the murderer pick up such a murder weapon casually?

The country of planting flowers has a very strict management of controlled equipment, except for special types of work, it is not allowed to possess weapons of large destruction, not to mention that they can still be obtained at hand.

Those who make film and television tools, sing and practice martial arts, and hold sharp weapons, not to mention sharp, are basically unopened and can't hurt people.

Ye Fan said a little bit for everyone to analyze, and thought in his heart, unless this person is a cultivator like her, or a martial arts cultivator, even if he is such a person, he must be a master, at least even if he is Lu Junyu's skill, he can't do this, maybe he has to be like her uncle to do it.

"This is indeed a big question, manpower is limited, and the strength of one hand is even more limited, even if I am afraid that it will be difficult for the king of soldiers in my previous army to do this. Team Chang said with a frown.

When Ye Fan said, Su Liang was busy on the computer, at this time he paused, and then said: "According to the palm print that Ye Fan just mentioned, I have roughly modified the data model, but the consistency is still not up to the requirements, I feel that the missing point is that the problem of the murderer killing people with one hand must not be as simple as we think." ”

"Well, murder weapons are also a problem. Xia Dong motioned for everyone to look at the autopsy report he came out, and said: "The broken neck of the deceased is too clean and neat, I have simulated all kinds of instruments, and with the current standard of the greatest human strength in the world, none of them can cause such a neat fracture." ”
