In front of several people, there are a total of three corpses, all of which have been numbered: the No. 1 corpse is the one that Jiang Chonglang checked just now, the one from the inner room, the one that has almost been burned out, and the No. 2 and No. 3 are the two corpses that were found in the living room, the degree of incineration of these two corpses is not as powerful as the No. 1 corpse, but from the appearance, it is also unrecognizable.

Body No. 1 has been examined and the cause of death has been determined. Jiang Chonglang asked people to remove his pelvis: the pelvis of this corpse is heart-shaped at the top, narrow at the bottom, the pelvic cavity is narrow and long, funnel-shaped, with a prominent anterior protrusion of the sacral promontory and a lower pubic angle of 7o75. Therefore, it can be judged that the deceased was male. Jiang Chonglang sent someone to remove his pubic symphysis and put it in the water to clean it up to determine the age of the deceased.

The second and third corpses were calmly placed on the operating table, and both corpses were in the shape of a fighting fist, the so-called fighting fist shape, which is a very common posture among people who were burned to death. As the name suggests, the joints of the limbs of the corpse are curled up, and it looks like a boxing fight.

It is generally believed that if the corpse is in the shape of a fist, it can prove that the deceased was burned to death before his death. In fact, this statement is not scientific: because at such a high temperature at the fire scene, a large amount of water in the human body is lost, and the muscles on the body will spasm, and the muscles will curl inward along with the joints on the body, such as knees, elbows and wrists, etc., and the posture presented is called a fist fight, so there is no way to judge whether the body is burned before death or after death.

How to determine whether the victim was burned to death before death or after death, presumably many people know: it is to autopsy and examine the body's mouth, nose, trachea, chest and other respiratory organs. See if there are any traces of soot inside. As early as the Northern Song Dynasty, it was recorded in the record of redress of grievances written by Song Ci.

Watching Han Yu pick up the scalpel and face it at the neck of the second corpse in it, ready to start moving. Ye Lili shouted beside him: "Brother, do you know how to use swordsmanship." Be careful to cut in the wrong place, affecting the autopsy results. ”

Han Yu didn't speak, but continued to raise and drop the knife in his hand, starting from the neck of the corpse and cutting it little by little. Since the skin of the deceased has been completely charred, the outside is very hard, and when you cut it with your hands, there is a crisp sound. The sound of this voice is very penetrating.

In the eyes of the layman, Han Yu's knife technique can hardly find a flaw. But Ye Lili, as a forensic doctor, really couldn't stand his knife technique, and was worried that he would destroy the corpse in the next second. So she picked up another knife, pushed Han Yu to the other side, and began the autopsy.

After the charred skin was cut, the muscle tissue inside was still relatively clear, and the trachea of the deceased's head No. 2 corpse was carefully cut by Ye Lili.

As Jiang Chonglang expected: there was neither congestion nor soot accumulation in the trachea of the No. 2 corpse. It appears that the deceased was dead before the fire burned.

Ye Lili continued to dissect the corpse and soon found the cause of death: the deceased had suffered a violent blow to the back of his head, which caused a skull fracture and died, and on the deceased's nose bone and back, there were bruises left by the impact or blow.

"Based on the injuries on his body, I guess the deceased should have been punched in the nose by the murderer as soon as he entered the door, and he was unsteady on his feet, and as a result, the back of his head hit the door, and the wound on his back should have been left by hitting the doorknob." Han Yu said on the side.

"As far as you know, come and help. I'm going to check his pelvis to see if he's male or female. Ye Lili said.

Soon, Ye Lili's scalpel came to the crotch of the corpse, separated the musculature around the crotch, pointed to the pelvis and said, "This person's pelvis is very similar to the first person." Therefore, the gender of the deceased should also be male. ”

The general autopsy of the No. 2 corpse came to an end, and Ye Lili left the scalpel in his hand and began to reach for the No. 3 corpse. Like the first two corpses, the third corpse had no signs of congestion or soot in its trachea.

"The muscles on both sides of the neck of the corpse have obvious signs of bleeding, and the thyroid cartilage has obvious fracture marks, which is a very obvious phenomenon of asphyxiation, and he was strangled to death."

"The deceased was a woman, because her pelvis was similar to that of the first two deceased: the upper mouth was approximately round, the lower mouth was wider, the pelvic cavity was short and wide, barrel-shaped, the sacral promontory protrusion was not obvious, and the inferior angle of the pubic bone was 8o1oo. This is clearly the characteristic of the female pelvis. ”

The cause of death of the three bodies had been determined, and Ye Lili and her assistants had each removed their pubic symphysis and placed it in a pot of clear water. After the dust on it has been completely cleaned up, the age of the deceased can be determined based on the symphysis pubis.

It took more than half an hour for Jiang Chonglang to take out the pubic bones of the three people from the water. It was determined that the three victims, two men and one woman, were all young men in their early 20s, all between the ages of 1822.

2o years old, is the best age of life. But a catastrophe, before the lives of several people began, in a fire, their lives were reduced to ashes. "So we cherish life, and at the same time pay attention to fire safety." Han Yu sighed.

"Small, don't be emotional. Xu Meng sent me a message just now, saying that the room on fire was rented by someone else. Now that the landlord has been found, Xu Meng has taken them to the information desk. Hurry up and pack up, change your clothes, and go. ”

When Han Yu finished changing his clothes and was about to leave. Ye Lili ran out and whispered, "Brother, thank you for comforting me so much today and relieving me again." Otherwise, I'm afraid that Team Jiang will scold me again. ”

Han Yu smiled: "Okay, leave." I know your feelings, besides, I am your brother and your leader, I don't protect you, who protects you. Isn't it? ”

Seeing that Han Yu was still smiling, Ye Lili was a little embarrassed: "Brother, I have been lukewarm to you during this time, sometimes you deliberately talk to me, and I pretend to ignore you." I didn't expect you to defend me like this, I..." Speaking of this, Ye Lili couldn't say any more.

"Okay, do you have it, do I have it? I don't remember how long these things have been, that is, you little girls are thoughtful, so you can remember it so clearly. Okay, I'm going to the interrogation room, the man has probably been waiting for a long time, I'm leaving. After hearing what she said, Han Yu only smiled and left.

Inside the interrogation room, a middle-aged man in his 4o years old sat opposite. Jiang Chonglang said: "You are the head of that room, right?" ”
