Zhang Heng thought for a while and said:

"First of all, I think which kind of murderer to kill Fang is determined according to the situation at the scene, the child is young, for an adult, it is much easier than killing a resistant adult, so the murderer doesn't care what method to use, look at the target, and then according to the surrounding environment, which method is the most convenient, which method is used, as for why the child didn't shout, such as the first case and the second case, the murderer has the opportunity to cover the child's mouth with one hand, press the child to the ground, and pinch or strangle with one hand, only the third case, It is necessary to seal the child's mouth before the knife can be released, perhaps the scotch tape is just the murderer's obsessive-compulsive disorder, and then the three victims have compression injuries on their faces, especially the second victim, who has obvious epidermis falling off on his neck, indicating that the murderer was wearing gloves when committing the murder, judging from the way the children died, the murderer in the three cases all brought a wide strip of scotch tape, a fruit knife, and a long and short rope similar to a shoelace, these Dong XZ can not be seen in the coat, and the way to commit the murder depends on the scene of the scene. ”

Hu Yang looked at Zhou Wang.

Zhou Wang subconsciously took out the cigarette first, and Dalong immediately reminded: "If you want to smoke it, you will take it out?" ”

Hu Yang smiled: "Bring me one." ”

Zhou Wang hurriedly smoked, and then lit it himself and said:

"I have a somewhat different opinion from Forensic Doctor Zhang."

Zhang Heng hurriedly said: "Just call me Zhang Heng, we are about the same age." ”

Zhou Wang was not polite, nodded and said:

"Zhang Heng just said that the murderer was similar to a random shot according to the situation at the scene, in that case, there is no way to explain that every child has pasted scotch tape on his mouth."

Zhang Heng said: "I also said just now, is it possible that the murderer posted it after the murder?" It's a kind of obsessive-compulsive disorder. ”

Zhou Wang took a puff of cigarette and said:

"I don't rule out this possibility, but the murderer committed a crime in the community, what he wants is to be fast, take out the scotch tape and cut it to about the same size, I think it is cut, because I saw the photo, unfolded the scotch tape, you can find that the two sides are very aligned, of course, this has to wait for the technical department to give the final conclusion, let's talk about the time of the crime, is there any need for the murderer to do more?"

Populus Hu motioned for Zhou Wang to continue.

"The time of the child's death is almost eight or nine o'clock, after the weather is cold, there will be fewer people in and out of the community at this time, but there will still be, and at the same time it is likely that someone will stand by the window of their house and look out, these are all possible to happen, the murderer shot three times and was not seen by anyone, or someone saw it, the light was not good and did not take it seriously, I don't think it was accidental, let alone random, not to mention, the three victims were found soon after the murder, the fastest was only two or three minutes apart, the murderer could still kill the child after Steady scissor scotch tape? ”

Dalong interface said:

"Except for the third case, it takes some time for the murderer to drag the body to the side of the van and stuff it under the car, that is because the child is playing outside, and the family will not soon find out that the child is missing, but the parents of the other two cases have a good sense of ritual after the murderer wants to kill someone, I am afraid that there is no time, which is different from putting a small car."

Hu Yang nodded with satisfaction, and motioned for Zhou Wang to continue.

Zhou Wang took a puff of cigarette and said:

"The first question, why did the murderer commit the murder in three ways? First of all, the victim child has no resistance injuries and restraint injuries, in this case, using a knife is the most troublesome, not to mention that it will leave blood stains, the murderer himself will be contaminated, and the child who was stabbed to death by a knife was fatal with five knives in the body, we also saw it during the autopsy just now, the depth is different, I personally think that in addition to showing that the murderer is rusty with a knife, there is also a ......"

"Guts! He's scared too! Dalong said.

Zhou Wang nodded and said: "So, there are three ways for the murderer to commit murder, I think the murderer arranged it for himself step by step and deliberately!" Strangulation, no need for his hand to touch the deceased, strangulation, no need to see blood......"

"If the murderer is in this state of mind, when he strikes again, the child may not be killed simply." Zhang Heng said.

Hu Yang nodded slightly.

Zhou Wang extinguished the cigarette in his hand, lit another one, and continued: "The second question, the murderer did not abuse the child, whether before or after death, why didn't the children shout in the third question?" ”

Speaking of this, Zhou Wang paused, not that he hadn't thought about it, but that he felt the same discomfort in his heart when he thought of the child's horror at that time, he took a puff of cigarette, clenched his fist tightly with his other hand, and continued:

"The three murdered children all had the opportunity to be alone for some reason, and the autopsy just now...... There is a problem here I can't figure out, scotch tape because of its special usage, it is difficult to operate with one hand, if it is not pasted after death, as long as his hand leaves the child's mouth, the child will cry even if he forgets to shout, there will still be people in and out of the community at that time, I don't think the murderer will risk letting go, this is one aspect, and again, we also looked carefully during the autopsy, the deceased's wrists, feet and necks were not tied, and there were no restraint injuries on the body, the murderer wanted the child not to shout can be covered with his hands, Let go of your hand, and the child will not only shout, but also run! ”

"It sounds like I was stunned first." Dalong said.

Zhou Wang nodded and looked at Hu Yang and said, "This is the answer to my third question, the child is stunned, but this volatile anesthetic, we can't test it." ”

Hu Yang asked, "What about the fourth question?" What did the murderer carry? ”

Zhou Wang extinguished the cigarette in his hand, thought for a while and said:

"I don't think the murderer will climb over the wall, because there is a great risk of being seen before the murder, I think the murderer will enter through the gate, but not walking, most likely sitting in the car, I mean sitting in the car, which means that he not only brought a murder weapon, scotch tape, stun children's potion, handkerchiefs and other things that can be hidden in his coat, but also a friend, a friend who drove to this community, or took a taxi to this community, or one of these three communities is where he lives."

Hu Yang stared at Zhou Wang seriously and asked, "How did you come to this conclusion?" ”

"Because the murderer didn't think about killing only one, since there is still the idea of murder later, he at least has to think about what to do so as not to be found by the police, the three crime locations are in different areas, it is enough to show his intentions, this kind of serial murder case, the police will generally find common ground, and it is also played like this on TV, so the murderer is very much like treating each murder as a separate one, you see, from the place of the crime, to the method of killing, there is no landmark common ground like other serial murder cases, I will boldly infer it, The process by which he may have arrived at the scene of the crime is also different, of course, this is only the current inference. ”

Zhang Heng saw Hu Yang's approving gaze, and immediately said:

"I agree with Zhou Wang's point of view, our usual idea is that the murderer will avoid a large number of people or a place with surveillance, this case, when he introduced the case before, he also said that he could climb the wall to enter and exit, but Zhou Wang's analysis is very reasonable, the murderer doesn't want to kill one and it's over, he has to continue, go over the wall, if he hasn't been seen once, it doesn't mean that he can't see it every time, unless he has a helper in the wall, otherwise he can't know what the situation is inside the wall before he shows up, what if there is a person standing under the wall? Or which one upstairs is looking at this side of the wall? The memory must be deep. ”

Hu Yang smiled and took out a box of cigarettes, one handed one to each person, Dalong hurriedly lit it for Hu Yang, Hu Yang looked at Dalong and said, "No wonder you are reluctant to enter the forensic department, you are a good master." ”
