After speaking, Xing Lao called Tian Zhen again and asked, "Girl, have you found out the injuries behind the deceased?" Is there anything about her that can give us some clues? ”

Tian Zhen walked in and said embarrassedly: "Teacher, you are embarrassed...... The deceased was just that sexual pajamas, where was there anything else? The puncture marks on your clothes match the wounds you've examined. ”

Xing Lao seemed a little disappointed, and asked again: "What about the bloodstains?" If the killer held down the victim with one hand and stabbed her with the other, the splattered blood would fall on his hand and form a barrier on his clothes. ”

Tian Zhen shook his head: "Teacher...... The kind of fabric of her pajamas...... A little blood was gone. Unlike clothes like shirts, this ...... It's too thin. ”

Xing Lao sighed, returned to the head, and pointed at the head with a scalpel like a teacher lecturing, "The high temperature has made the deceased unrecognizable, and there are red spots, blisters, carbonization and other phenomena on the skin. However, this does not prevent careful examination and observation from showing that the deceased had put on makeup before his death. ”

Luo Chuan nodded: "Looking at what she is wearing, it can basically be inferred that the person she is waiting for should not be an ordinary relationship." ”

Xing Lao touched the head lightly again and said, "Whether it is a high fire or an oven, high temperature will destroy the organic matter of the bones and make them crispy. In particular, the bone marrow cavity of the skull and neck is fractured due to the formation of air bubbles. As forensic doctors, we must first rule out whether these bone fractures are mechanical injuries before death or natural formation of high temperatures. I examined them carefully, and these fissures were pseudo-fissures, and the wounds were shallow, only affecting the epidermis. So, it's not caused by external forces. ”

After speaking, Xing Lao walked to the dissecting table again and said, "After talking about the beautiful head with heavy makeup, let's talk about this body." I was sure there was no trauma to my head, but I found a bruise on my shoulder. The preliminary judgment is that it should be caused by the handle of the murder weapon. ”

Luo Chuan took a closer look, and the small patch of bruising was especially obvious after the deceased's blood stopped circulating. It was like a curved square, and it did resemble the handle of a knife.

Since no murder weapon was found at the scene, it is important to infer the causative object based on the morphological characteristics of the injury.

A variety of causative substances can give injuries a variety of forms. Even under similar conditions, damage caused by a blow to a certain part of the same object can cause different forms. Different parts of the human body can be shaped by different anatomical and histological structures.

Only an experienced forensic doctor or criminal police officer can judge the force, speed, angle, and direction of the blow based on the wounds on the body of the deceased at the end. That's why Elder Xing pays special attention to this small bruise, which is a little insignificant compared to other major traumas.

At this time, Luo Chuan patted Guan Shan and asked him to stand still. Then he walked to Guan Shan's back, put his left hand on his shoulder, and made an attack gesture with his right hand, and was stunned for a while in this position, and then judged the angle according to the depth of the bruise, and finally said: "The murderer should be about the same height as the deceased, not more than ten centimeters." And he was a little flustered at the moment of his move, and when he attacked the deceased from behind, he did not succeed once, and he only had this bruise in the struggle. ”

Xing Lao immediately flipped through his records and said, "I counted my head and measured it, and the deceased's height should be about 167 centimeters." ”

Tian Zhen answered on the side: "That means that the murderer should be a ...... No more than 177, not short with 157 people? This...... The range is a bit big. ”

Guan Shan slapped Luo Chuan's hand and said decisively: "It can't be around 157, at least it must be at the level of the deceased to cause this scar from top to bottom." Old Xing, what about the fatal wound? ”

Xing Lao stood in front of the corpse, pointed to the wound on the deceased's back and said, "Combined with the size of the bruises, coupled with the shape of these injuries, I feel that the murder weapon should not be a big one." It's almost a short-edged cutter, such as a fruit knife, a scalpel, a razor, ......."

Before Xing Lao finished speaking, Luo Chuan pointed to the neck of the deceased after being beheaded, and asked tentatively: "Old man...... I'm afraid the razor can't satisfy this method, right? ”

Xing Lao glared at Luo Chuan impatiently: "I'm talking about these back injuries!" Anyway, it must be a cut, the wound is here, and the murder weapon is definitely not too big. As for what kind of guy was used to cut off the head, you should ask the police officer who is investigating at the scene and ask them if they have lost a kitchen knife or a bone chopping knife or something like that in the deceased's home. ”

Guan Shan stood next to Luo Chuan, and a almost inaudible sigh attracted Luo Chuan's attention.

"What's wrong? Did you think of something? Luo Chuan looked at him.

Guan Shan shook his head and said, "I just thought that since it was a cut, the most common consequence was hemorrhagic shock. These scars are not in the arteries and cannot cause death in the quickest possible time...... And the murderer couldn't wait there for her to be completely dead before making a move, so ......"

The second half of the sentence that Guan Shan didn't say, Luo Chuan took it: "So it proves that this girl was still alive when her head was cut off." ”

In a word, the atmosphere in the entire forensic room was solemn. Tian Zhen and Haixin stood behind Xing Lao, looking at the deceased with mixed emotions in their eyes. As a forensic doctor, I have seen how cruel the way to die, but professionalism cannot detract from the kindness of the heart. After hearing such a terrible killing method, even if they are used to death, they still can't help but feel a chill.

After a while, Xing Lao was the first to break the heaviness, he looked at Luo Chuan and said, "It's true, but the deceased's hands didn't resist the injury. This is because she has no ability to resist, and secondly, it may also be because of the position. The skull was scorched, and there was no way to detect any more scalp damage. In such a way as beheading, there is no way to deduce the angle of the first knife. But I have observed the part of the deceased's throat where the flesh is turned up, shallow on the left and deep on the right. ”

Luo Chuan's eyes lit up: "Ah, that means that after the murderer cut the deceased, the deceased lay on the ground." Then the killer pulled her hair from behind the deceased, forced her to look up, and cut her throat with a knife in the other. To put it this way...... Isn't it less painful. ”

Guan Shan glanced at him helplessly: "You ...... It's a bit misleading. If the murder weapon was really just a fruit knife, even if it was in the neck, it would be impossible to kill the air on the spot. ”

Luo Chuan's original intention was to let the two girls in the forensic room not be too heavy, but he didn't expect Guan Shan, who has always been empathetic, to splash over with a bucket of cold water, and there was a feeling that the more he depicted, the more bloody he felt.

Haixin looked at Guan Shan with admiration, then at Luo Chuan, and finally asked: "Teacher Xing's sentence is shallow and deep, can you restore the murderer's actions at that time?" ”
