Captain Wu cleared his throat, and then took the file seriously and said, "The deceased Feng Gang, 42 years old, is now contracting the transportation team. Pen & Fun & Pavilion www.biquge.info I haven't heard of any enemies or people who make him have to die. ”

Mu Sen sneered and said, "How can such a person have no enemies. Come, let's move on, what happened to the first few deceased? ”

Captain Wu flipped through the file in his hand, pouted and said, "Actually, there is nothing to say, some of them are engaged in the timber business, some are raising large trucks, and some are engaged in real estate." Different industries, different origins, and even more different residences are not much related. ”

Mu Sen listened carefully to Captain Wu's words, and then said to himself: "Timber, transportation, real estate...... Actually, they're not completely different, and together they are a construction site, don't you think? ”

Captain Wu was stunned for a moment, and then said hesitantly, "Eh...... Otherwise, I'll let them find out what these dead people did before? ”

"Well, check ahead, check carefully. Don't limit yourself to a year and a half, and check the previous ones. Mu Sen said, and remembered Dong Hua's case. That case was more than two years ago, and just when everyone was about to forget it, the former victim suddenly broke out and began to take revenge. Therefore, Mu Sen reminded Captain Wu not to be limited to a certain time period.

Captain Wu arranged the task, and then discussed it with Mu Sen and the others: "You said that the nail marks found on the neck of the deceased must be the murderer's?" ”

"What do you mean? Are you trying to say that the deceased tried to strangle himself? Mussen asked, raising an eyebrow.

Without waiting for Captain Wu to speak, Mo Ziqi on the side categorically denied: "That's impossible." Self-choking is a situation that simply cannot happen. If you choke your neck, when consciousness begins to be lost, the muscle tone of the limbs will also disappear rapidly, and it will be impossible to continue to complete the choke movement. ”

"Does he have any other signs of resistance or poisoning? Wouldn't it be strange if not? A big man, just let another old man choke his neck and not resist? I always think that when two men fight, unless the difference in size and physical strength is too great, it is really impossible to say who will kill whom. How could this murderer be so easy to get his hands on? And you see, these deceased people are not bad in shape, not like people who can be easily strangled to death. Captain Wu said his thoughts as he put the photo of the deceased in front of Mu Sen and Mo Zidi.

Mo Ziqi gently picked up the photo of the deceased, and then said calmly: "I have done a study to test the characteristics of injuries on suspects in 20 cases of strangulation, 12 cases of strangulation, and 5 cases of strangulation and strangulation at the same time. Of the 37 cases, 25 had visible injuries to the killers, and 13 suspects had hundreds of scratches on their bodies. These are all injuries caused by the victim's resistance at the time of the murder. However, in only 6 of the 37 cases, the victims had obvious resistance injuries. It can be seen that there is no correlation between whether the suspect has injuries or not and the injuries on the corresponding victim's body, and it cannot be judged from the victim's physical injuries that he struggled and resisted before his death. ”

At this moment, Captain Wu was also completely speechless. He couldn't question or question Mo Zidi's assertion anymore.

At this time, Mu Sen asked Mo Zidi, "Can you restore the crime scene through the scars on the deceased's neck?" ”

Mo Zitong smiled helplessly and said, "Mu Sen, are you treating me as an immortal?" The restoration of the real crime scene needs you, and all I can do is restore the moment before the deceased died. ”

"Just that moment, you say." Mu Sen stood up with some excitement and lit a cigarette. Captain Wu listened in a daze, whether he understood it or not, but he looked very nervous.

Mo Zidi also stood up, he walked in front of Mu Sen, then stretched out his right hand and gently put it on Mu Sen's neck, and then explained vividly: "The deceased found today should be like this before he died, the murderer was located in front of the victim, strangled the victim's neck with one hand, pressed with his thumb / on one side of the neck, and the other four fingers pressed / on the other side of the neck, and pressed the larynx, trachea and other neck organs to the back and upper with the force of the palm of the tiger's mouth, thus causing airway occlusion. ”

After speaking, Mo Ziqi took his hand away, pointed to the place where his thumb had just been pressed and said to Mu Sen: "The nail damage I found is in this position." This proves that the first shock to the dead is what I just looked like. But to be honest, strangling your neck with your hands is a laborious and long job. In reality, the situation is not like what is played on TV, as soon as you grit your teeth and choke it, you die. The fact is that the jugular vein can be completely occluded because the thumb and four fingers are pressed separately from both sides of the neck, but the carotid artery is not easily occluded, let alone the vertebral artery, which is even less likely to be crushed. Therefore, such a way of death can only be caused by cranial congestion and lack of oxygen in brain tissue caused by strangulation. The process of asphyxiation can be very long, the loss of consciousness will occur very slowly, and the process of death will be very long. ”

"So, do you think that the murderer not only used the method of strangulation, but also used other forces or tools to strangle the deceased?" Mu Sen reacted very quickly and understood the meaning of Mo Zidi's words.

It's just that Mo Zitong said with some hesitation: "I'm not sure what it is, because the deceased was hanged by his neck after his death, and the time is not short." The ditch has been formed, and it is very deep. It is not entirely certain whether there are any scars that coincide with the ditch, or what artifacts caused them. After the forensic doctor has completed the dissection of the subcutaneous tissue at the gutter, some conclusions may be reached. ”

Mussen walked a few steps back and forth around the table, no one knowing what was going on in his head. I saw him suddenly stop and ask Mo Zitong: "You just emphasized the pre-death situation of the deceased just now, what does this mean?" Are the conditions of several of the deceased different? ”

Mo Zitong was very satisfied that Mu Sen heard his voice, so he walked to Mu Sen's side again and said: "That's right, I read the autopsy report, and it is certain that except for the first deceased, the rest of the deceased died in this way, only the first deceased ......."

As he spoke, Mo Ziqi walked around behind Mu Sen, then stretched out his right hand and gently choked Mu Sen's neck from Mu Sen's back with his elbow, and said: "Only the first deceased, the murderer strangled the victim's neck with his elbow or the radial side of his forearm from behind the deceased. Of course, it is also possible that the murderer faces the victim and presses the back of his elbow against the victim's neck and pushes it against the wall or the ground to increase the pressure of the chokehold. Therefore, only the neck of the deceased was found with no strangulation or injury to his fingers and nails. ”

Mu Sen turned his head sideways, glanced at Mo Ziqi behind him and said, "In this way, this first victim is very important to the murderer, and all the hatred may be triggered by him." That...... It may be this person he wants to punish. ”

After speaking, Mu Sen decisively said to Captain Wu: "Team Wu, focus on investigating the first deceased, he is most likely related to the murderer, and even, they may know each other." The more people they know and have an enmity, the more they need to attack and die from the rear or in a more violent and rapid way. Because of the understanding, there will be precautions, so the murderer can only solve the problem in a faster way. ”

As soon as Captain Wu answered, the phone in the office rang. It turned out that the results of the investigation had come out, and a police officer was being sent to the office.

After Captain Wu took over the investigation results and read them, he raised his head in a daze, and then looked at Mu Sen and said: "This, these people seem to have been in charge of the construction site...... What surprised Captain Wu so much was Mu Sen's speculation. He was able to predict that the deceased's industry must have crossed paths in the past few years without any clues and information! This is really a wisdom that Captain Wu can't even think of.

Mu Sen nodded deeply, then took a deep breath and said to Captain Wu: "For the sake of your official clothes and black gauze hat, I suggest that a meeting be held now to publish the criminal's profile." ”

"You...... Do you already know who the culprit is? Captain Wu's eyes were about to pop out.

Mu Sen shook his head and smiled: "Who it is, I don't know." It's up to you to find out who it is. All I can do is do my best to give you clues and profiles to narrow down the scope and time you have to catch the suspect. ”

As long as Captain Wu almost let himself be stripped of his coat when he thought of the overpass dead body case, the anger in his heart would not come anywhere. So at this moment, as soon as he heard Mu Sen's words so confident, he couldn't help but say: "Brother, can you tell me first, what is that grandson doing?" I wondered how he could have done such a thing, and no one would find out! ”

Mu Sen smiled mysteriously, and asked rhetorically, "Then Captain Wu, what kind of person do you think can do this kind of thing on the overpass in the middle of the night without being discovered?" ”

"I think? If I think it wouldn't have happened! There are so many warning signs at the entrance of each overpass, and there is a sign like a little man drawing a fork on it, can't you understand it? Pedestrians are not allowed to walk up and walk around it! Then you say, how did he get up! Captain Wu said with some excitement.

Mu Sen was very indifferent, and when Captain Wu was over, he said with a slight smile: "He just drove up normally, and then parked normally, tied up the rope, threw the corpse, and then drove ......away."

Captain Wu glared in surprise after hearing this, "This, how can this be ......?"
