The first thing he did when he returned to the police force, Mu Sen put on gloves and a mask and followed Mo Zili into the forensic office. Before www.biquge.info entered, he hadn't forgotten to tell Captain Wu, "Team Wu, I believe in your ability. I hope that when Zi Di and I come out, we will be able to hear the good news that you have found the source of the corpse. ”

Captain Wu is a face-loving person, so now that Mu Sen said this, he immediately responded and said, "Don't worry!" It's up to me. Four corpses, you are busy, you can do an autopsy with peace of mind. As for the matter of finding the source of the corpse, leave it to me, maybe I have already solved it all before you are done. ”

Regarding Captain Wu's bold words, Mu Sen just smiled, didn't say anything, turned around and walked directly into the forensic office.

In the forensic room, facing the four corpses that died miserably, the faces of the forensic doctors were also a little unpleasant. Because it would mean that they don't want to rest this night.

Mo Ziqi stood in front of the first corpse, looked at the unrecognizable corpse and said, "This is a typical blunt force injury. According to statistics, blunt force injuries account for 28% of homicides, which is a relatively common form of homicide. ”

Then, Mo Ziqi carefully observed the body's body, head and other injuries, and then said very professionally: "The corpse has a long strip of subcutaneous hemorrhage, the center/position of the wound is very heavy, and gradually lessens to both sides, the boundary is not clear, and there is an island-like epidermis falling off within the scope of the blow. It can be concluded that the murder weapon was a cylindrical club. ”

After listening to Mo Zidi's narration, several other forensic doctors in the forensic office took two steps back very tacitly.

Mo Ziqi bent down slightly, looked at the deceased's abdomen, and continued: "Due to the rapid and powerful blow of the wounded object to the deceased's chest and abdomen, the skin in the center/position was quickly pressed down vertically, and its pulling force tore the blood vessels on both sides. As a result, hollow damage, that is, rail damage, is formed. And this kind of injury is most likely to form a round rod-shaped object such as wood and bamboo, so this kind of injury is also called a stick punch hollow. Therefore, I think that the causative object that caused the death of the deceased should have been a round wooden stick. ”

The forensic doctors surrounded by "......" seemed to have changed from professional forensic doctors to interns at this moment, and they all gathered around Mo Zidi, listening to Mo Zidi's explanation seriously.

Mu Sen also felt helpless watching from the sidelines, it was obviously a nervous autopsy, but now it seemed as if Mo Zidi was making up lessons for these forensic doctors.

At this time, Mo Ziqi turned to the head/position of the corpse again, carefully observing the wound. Mu Sen also believed that the fatal injury must have been on the head, because the blow was so hard that a third of the entire head was sunken in, and the body looked like half a head.

Mu Sen reminded Mo Ziqi and said, "Zidi, can you deduce the height and size of the murderer from the wound on the top of your head?" Be sure to check it carefully, your judgment is very likely to shorten the time to solve the case a lot. ”

Mo Ziqi was still observing the head of the corpse, and did not answer Mu Sen, but continued: "A blow to the head with a wooden stick usually only forms a linear fracture, and a blow with an iron rod will form a depressed fracture. However, the deceased, due to repeated heavy blows to the head, developed a scaphoid depression fracture and comminuted fracture. Although I can't tell the height of the murderer, this injury must have been caused by his 120 percent strength and frantically hitting. How can this be without a blood feud? ”

"So, what you're trying to say is that the killer doesn't kill people randomly. The causes of death of these deceased must have had causes and effects. Once the source of the body is found, it is right to immediately find out the enemy of the deceased. Mu Sen easily understood what Mo Zi Di meant.

Mo Ziqi nodded slightly and said: "Judging from the life reactions on the corpse, it should be all injuries before death, and there are some not deep binding marks on the wrists, and we will not know if I have been stunned after the dissection, whether there are any signs of drug poisoning, etc." ”

"Well, you go ahead." Mussen gestured to the second corpse beside him.

This body was the only one of the four bodies to be burned. The surface of the corpse has been charred, and it is showing a terrifying posture of burning to death.

Mo Ziqi looked at the limbs of the corpse and said, "This corpse should be the most difficult to judge among the four corpses. Because he is so charred that a light touch will cause a part to be missing. What's more, he was also buried, and he was taken to the abandoned building to be hanged, and in the process of carrying the body, I don't know how many parts/bits will be missing. You see, half of the right arm is missing, and you have to dissect it carefully to know whether it was lost after death or if someone cut it off before death. So, let's look at the next one first. ”

Mu Sen nodded in agreement, and followed Mo Ziqi to the third corpse.

As soon as he glanced at it, Mu Sen spoke first: "This is a brick injury, right?" I have to say that the tragic situation of the corpses in this case is really more serious than the other. ”

The reason why Mu Sen could say this was because the corpse in front of them was already bloody and fleshy above the cheekbone on the left side of his face. To put it more bluntly, it was a brick or something like that, and it smashed its face.

Mo Ziqi looked at the debris on the edge of the wound and said: "The injured object is clay bricks, this kind of brick mainly contains silica, cobalt, iron, etc., the brick weighs about 2.5kg, and it is the whole brick that hits the head and face of the corpse, until the brick is broken during the beating, and the murderer uses the remaining half to continue to hit." ”

At this time, the forensic doctor on the side couldn't help but speak: "Who did these four people offend?" How could they be treated in such a cruel way? I think they all must have suffered a great deal before they died. ”

"That's inevitable, the injuries to the head and face of the corpse will not kill all at once, they are all caused by multiple gravity strikes. So, of course, they endured great pain before they died. But I'm starting to wonder now, is it really the same person who did it? Using different tools, different methods, and different methods to kill people, what is the purpose of time-consuming and labor-intensive? Mo Ziyan looked at Mu Sen in confusion.

Mu Sen thought for a moment, then replied, "I think...... These different ways of dying are likely to represent the cause of their death. Perhaps, the murderer was taking extreme revenge, and he was punishing the four dead with what he felt was due. ”

Mo Ziqi shrugged his shoulders slightly, then pointed to the bloody face of the corpse and said, "The brick plane is vertically striking the full/full part of the soft tissue of the face, so this rectangular hollow wound is formed. It was precisely because of this wound on the right cheek that I judged that the murderer originally used a whole brick. The roughness of the bricks caused punctate scratches. This half of the scalp peeled off, and the force of the blow was too great, forming a star-shaped contusion, and there were brick chips left around the wound. When the murderer strikes the deceased on the head, the speed must have been very fast. Therefore, it is clearly visible that the linear fracture and the separation of the bone sutures. Oh yes. In addition, the deceased had also suffered a strong beating in the chest and abdomen, which resulted in two broken ribs and bleeding from the spleen. ”

Listening to Mo Ziyun's light analysis of the miserable corpse in front of him, Mu Sen slowly stretched out his hand and pointed at the seriously injured left side of the deceased's face and said, "You...... Do you want to talk about it again? The left half of the face is no different from the loss, and it's also caused by bricks, right? ”

Mo Ziyan went around to the other side, looked at it and replied: "The injury on this half of the face is indeed very serious, a wide abrasion can be seen on the edge of the wound, a skull fracture line can be seen at the bottom of the wound, and there is an intertissue bridge in the left lateral and lower part of the wound, which should be caused by the blow of the brick edge." There are three-angled, strip-shaped epidermis peeling off on the scalp, and the most striking force has even formed a three-angled contusion, in which the tissues of the skull and scalp can be clearly seen. At the same time, it is accompanied by a three/angular concave fracture. ”

Mu Sen turned his face away and said to Mo Zidi: "These four people either encountered a perverted murderer who killed people for no reason, or they were guilty of a lot of sin in life. My judgment now is that the latter is more likely. Because not many murderers would be willing to put that much effort into an ordinary prey. ”

"You're right. Take the corpse in front of him as an example, if you can smash him beyond recognition with a turn of his head, the murderer himself must be exhausted, and his right hand will be injured. ”

"How do you know it must be the right hand?" A young forensic doctor couldn't help but ask.

"Because the left side of the deceased's face was the most seriously injured, the entire skull was dented. Therefore, only right-handed people can do it. Mo Ziqi replied simply.

"So, how do you know that the murderer's right hand must be injured? What if he wore gloves? The young forensic doctor still asked unwillingly.

Mo Ziqi didn't even look at him, and continued to look at the corpse and said, "The force of breaking the bricks on a person's skull is definitely not small. Even if he wears gloves, repeated and vigorous blows will cause external injuries to the tiger's mouth. He's using bricks, and he's bound to get hurt. Mo Zitong said firmly.

didn't care about the competition between the little forensic doctor and Mo Zidi, Mu Sen listened to these on the side, and he was very happy. Because the most powerful evidence of a crime to arrest a suspect is the wounds on the criminal's body. If there is such an affirmation as Mo Zidi, then no matter how many suspects are found in the future, it is a good way to eliminate them by checking their right hand first.

Thinking of this, Mu Sen felt that this strange and bizarre murder case had begun to have some eyebrows, and the clues were getting clearer and clearer, and it seemed that he was one step closer to the truth.
