Rebirth of the open female forensic doctor

Chapter 279 This is wrong

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

Everyone's eyes turned to her, and Su Liang's eyes brightened even more, expecting that she would find something that he hadn't noticed, so that he could perfect the blood splatter simulation even more.

"That's right, Ye Fan, is there a place where the data in my simulation is missing, or is it wrong?"

"I agree with the simulation done by Brother Su. Although the matching rate is not 90.00%, or even [-]%, the comparison of the two maps can prove that the deceased was lying on his back when he died, not standing, so the clothes It may be completely ruled out that the stain was caused by being pressed against a colored wall or a mural while standing."

With a pen in his hand, Ye Fan clicked on the simulated screen, his eyes focused and serious, and his voice was serious and unwavering: "But, brother Su, please forget a little bit, the palm print I printed on the deceased's right thigh."

Su Liang's expression was shocked, and Ye Fan asked again: "Brother Su, have you tested that palm print? Can you get the fingerprint?"

"Qian Qian." Su Liang looked at Qian Qian. He was in charge of some of the most important testing experiments. Qian Qian was his assistant, responsible for some more detailed technical testing work. The palm print printed on the thigh of the deceased was his. Responsible.

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

"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 meticulously, the printed fingerprints are too fine to be recognized." Qian Qian said with a little disappointment .

"There is no other way, the environment at that time... Ye Fan, you have done a good job." Afraid of Ye Fan's loss and self-blame, Team Chang quickly comforted him.

Ye Fan is not so glass-hearted. She has long expected that without professional tools, the collection and preservation of physical evidence cannot be completely intact.

"It's okay. Although you can't get a complete fingerprint, it's not without gain. At least it proves that the murderer didn't wear gloves when he committed the crime. He only put on gloves after the murder..." Said Here, something flashed through Ye Fan's mind, but unfortunately it flashed too fast and he didn't catch it.

I had to put it aside temporarily, and continued: "And what I want to talk about is not the issue of fingerprints, but the circumstances under which the murderer grabbed the deceased's thigh."

"Cough cough..." There was a coughing sound at the scene. Although he told himself that he had nothing to worry about, the male compatriots couldn't help coughing and blushed.

Su Liang, a technical geek, has the purest mind, he slapped his palm suddenly and said, "I see, I understand what I missed in this simulation graphic."

He released the simulation picture again, and pointed at the female model's hanging right leg with a projection pen, saying: "At that time, the posture of the two people, the murderer should have grabbed her thigh like this, using force, so the deceased's leg is upturned." up, and the curl of the skirt is also different."

"Yes, a slight difference may cause a big deviation."

Ye Fan nodded, and spoke out the image in his mind: "When the crime happened, the murderer put the deceased on the ground or on the table, and grabbed her thigh with his right hand, and the skirt was rolled up. At this time, the deceased Either restrained or insane, the murderer took the opportunity to pick up the murder weapon and cut off the head of the deceased."

As she said that, she frowned and said, "It's just something wrong here."

Following Ye Fan's words, combined with the simulation map, there were specific images in everyone's minds, but it was a bit unsightly, and then looked at the little girl's pure and serious eyes, which made their minds too wretched.

"What's wrong?" Su Liang asked.

"At that time, if this was the case, the murderer grabbed the thigh of the deceased with his right hand, then he held the murder weapon with his left hand..."

"The murderer is left-handed?" Chang Dui's eyes lit up.

"It's possible, but my question is, even if this person is left-handed, in such an environment, he can chop off a person's head with one hand, then this person's strength is somewhat beyond the range of ordinary people." Ye Fan lightly clasped the tabletop with his fingers, muttering.

The human body is both fragile and hard. Even the butchers who slaughtered pigs and chopped bones all the year round, the executioners who beheaded people in ancient times, if they want to cut off a person's head cleanly with one knife, they still need to hold a knife in both hands and use force. The strength of the whole body, this can only be achieved by those with amazing strength and professional skills. Many of them cannot be cut with a single knife, and they need to be cut several times.

And no matter whether it was a butcher or an executioner, the bone-chopping knives and execution knives used were thick, large and extremely sharp.

According to the previous speculation about the scene of the first crime, it should be in or near a public area. How did the murderer keep the weapon with him without being noticed? Such a murder weapon is carried around without arousing suspicion.

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

The flower-growing country has very strict management of control equipment. Except for the needs of special types of work, it is not allowed to possess large-scale lethal weapons, not to mention that they can be easily obtained.

Those who make film and television tools, sing opera and practice martial arts, the weapons they hold, let alone sharp ones, are basically unopened and cannot hurt people.

Ye Fan said a little bit for everyone to analyze, and thought to himself, unless this person is a practitioner like her, or a martial artist, even such a person must be a master, at least Lu Junyu's skill, She couldn't do that either, maybe she had to be like her uncle to do it.

"This is indeed a big question. The manpower is limited, and the strength of one hand is even more limited. I'm afraid it would be difficult for the soldier king in my former army to do this." Chang Dui frowned.

When Ye Fan was talking, Su Liang was busy on the computer. At this moment, he paused, and then said: "According to the palm print that Ye Fan just mentioned, I roughly modified the data model, but the degree of fit is still up to Not meeting the requirements, I have a feeling that what is lacking is that the murderer kills with one hand, it must not be as simple as we think."

"Well, the murder weapon is also a problem." Xia Dong motioned everyone to look at the summary of the autopsy report he produced, and said: "The neck fracture of the deceased was too clean and neat. I simulated various instruments. Based on the current standard of the greatest human strength in the world, None can make such a clean fracture."
