Su Yi was silent and began to check Lao Liu's head, she picked up the back of Lao Liu's head with both hands, and repeatedly touched Lao Liu's long hair with her fingers. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

After touching it for a while, she suddenly felt as if there was a small crack in her pillow, but she couldn't be sure, so she said, "Murong, the pillow seems to be a little injured." ”

Murong Fei was checking Lao Liu's chest and abdomen, Lao Liu's chest and abdomen were not damaged at all, not even a slight abrasion, he heard Su Yi's words, and said, "Oh? What kind of injury is it? ”

Su Yi continued to repeatedly confirm with her fingers at the injured site that there was indeed a small wound in the occipital, she said, "I feel that there is a small wound, why don't you turn it over and take a look?" ”

Murong Fei had already finished checking his chest and abdomen, and had already asked Shen Hai to take a photo, so he said, "Okay, my side is over, let's turn him over together." ”

When turning over the corpse, Murong Fei found that Lao Liu's corpse stiffness was already very strong, and the time of the strength display and the corpse spots corroborated each other, and the time of death was about ten hours, that is, it was about between eleven and twelve o'clock last night, and the traffic police Xiao Zhang said that Lao Liu had handed over to him at eleven o'clock, so the range of death time could be narrowed.

After the corpse turned over, Lao Liu's occipital part had become upward, Su Yi touched his occipital part for a while, and after finding the original cleft, she pulled away the hair around the cleft part, observed it for a while, and found that it was really a wound, but this wound was only less than a centimeter long, Su Yi said: "Oh, this is this wound, very small, it doesn't seem to be fatal." ”

After Murong Fei saw it, he touched it with his hand, he felt that although the wound was small, the surrounding scalp tissue had been poked, and he said: "No, it's not good to say that for the time being, whether the damage is serious or not, you can't just look at the size, you go and get a scalpel." ”

Su Yi was puzzled: "Do you want to dissect now?" ”

Murong Fei shook his head: "It's not an autopsy, it's a shaving of hair, you shave off the hair in this area, on the one hand, it is convenient for photography, and more importantly, it is convenient for us to observe." ”

Su Yi knew that Murong Fei's consistent view was to expose the observation surface as much as possible, so that he could open his horizons.

She turned around and took the scalpel over, installed a new blade, and wanted to hand it to Murong Fei, but the outstretched hand took it back, thinking to herself, Murong Fei just asked her to shave herself.

Su Yi remembered that Chi Ming had mocked her before, when she said that she was the "second knife" of the seventh group, Chi Ming mocked her for "handing the knife", thinking of this, she couldn't help but be happy, because she felt that she had indeed been playing the role of "handing the knife", and handing the knife was also willing, a good teacher like Murong Fei, where to find it?

She began to shave Lao Liu's hair, exposing an area, and at this time, the wound appeared more obvious under the contrast of the gray and white color of the scalp.

Murong Fei looked at it and said: "You see, the characteristics of this wound have been exposed, the wound is small, but the surrounding soft tissues have become crushed, which shows that the force is quite huge." ”

Su Yi took the scalpel, stood up straight, and asked, "What kind of tool hit it?" How can there be so much power? ”

Murong Fei shook his head and said, "I'm not thinking about a blow now. ”

Su Yi was even more confused and asked, "Isn't it a blow?" How did the damage come about? ”

Murong Fei explained: "I suspect that it was injured on the ground. ”

Su Yi opened his mouth wide: "Hurt when you fall to the ground?" ”

Murong Fei knew that Su Yi's experience still didn't have a basic concept of falling to the ground and injuring him, if he hadn't experienced it many times, it would be hard to believe that after a person fell to the ground, the head collision would have so much force.

So he began to explain in detail: "I've always heard of falling to the ground, right? I look at it this way, Lao Liu's head fell to the ground, and his head hit the ground, from the perspective of the injury formation mechanism, it is a kind of deceleration movement, which is equivalent to a moving car to hit a still life, and the force depends on the weight and speed of the moving object. ”

Su Yi finally understood what Murong Fei meant, and said: "Roughly understood, it is equivalent to hitting the ground with a person's weight, the force is immeasurable, so if the damage is so small, it will not lead to death, right?" ”

Murong Fei shook his head again and said, "No, because of the particularity of the brain structure, this kind of damage is also special, we see that the damage is so light on the outside, but it is possible that the brain is a mess inside." ”

Su Yi blinked and asked, "What's the mess?" ”

Murong Fei continued: "When the head hits the ground, the whole head stops moving, but the human brain tissue is because there is a gap between it and the skull, and the brain tissue itself is a soft substance, so it continues to move, hitting the skull, it is simply equivalent to hitting an egg against a stone, and as a result, the brain tissue is crushed." ”

Su Yi still didn't understand: "There are abstract explanations in the book, they are all mechanical principles, it doesn't seem to be such an image, I really want to dissect it." ”

Murong Fei was a little embarrassed and said: "Alas, if it weren't for Lao Liu's corpse, I wouldn't have thought at all, but in the face of my own acquaintances, it's really a bit difficult to use the knife." ”

Su Yi also said regretfully: "Yes, Lao Liu is actually quite cute, and he has also helped us a lot." ”

Murong Fei closed his eyes slightly, as if recalling Lao Liu's appearance before his death, and said, "Alas, could it be that what Lao Li just said is right?" Lao Liu suddenly lost his life overnight and inexplicably, is this the rationality of their theory? ”

Su Yi knew that Murong Fei was a little sad, but she knew that the case was important at the moment, so she said, "Murong, what do you think we are going to do next?" Do you want to investigate the scene first? Or take Lao Liu's body back to the autopsy room of the criminal department for dissection? ”

Murong Fei opened his eyes, glanced at Lao Liu's body lying prone on the corpse bed, and said: "It is more important to investigate the scene, at present, I consider that Lao Liu fell to the ground and died, and I could have considered whether it was formed by an accidental fall, but his corpse ran to the corpse bed, which is the first incomprehensible point, and second, one of his front teeth was extracted after death, that is to say, at the time of the incident, there must have been a second person involved in it, and the other point is that the nameless corpse sent by the traffic police is now missing, So no matter what the nature of the back, we must find out the truth and call Chi Ming to come over as well, this morgue is currently our scene. ”

Su Yi suddenly remembered something, and she said, "It is impossible for that nameless corpse to disappear for no reason?" Is it possible that you said it had been cremated? ”

Murong Fei was stunned and said, "If that's the case, the management of the funeral home is too chaotic, when Wulong comes, let the detectives investigate them." ”
