While opening his toolbox, Guan Zengbin looked up at the steel bar in Gu Chen's hand, and said, "There should be no such steel bar in the world, and no manufacturer would make such a steel bar. This means that , the steel bar was made by the murderer himself. Then, the murderer still has this technology.”
We nodded.
"Murderer, how did you impale two people at the same time?" I frowned and said while looking at the steel bars.
Gu Chen looked at me, gestured in the air with the steel bar, and said, "Just like me, grab one end of the steel bar, and then stab at the two people on the bed."
"No." I stretched out a finger and shook it, then said, "Gu Chen, did you use a lot of force when you pulled out this steel bar just now?"
Gu Chen shook his head and said, "I think it's quite relaxed."
I was helpless, and then said: "Not everyone has muscles like yours. From various traces and testimonies, we can be sure that the murderer must be a short, thin person. Such a person wants to stab the steel bar It's not an easy thing to enter into the bodies of two people."
Xiao Liu widened his eyes, and then said: "Do you think there is only one murderer? The murderer is sometimes thin and sometimes strong, and the murderer is sometimes male and sometimes female. I'm afraid, you really guessed wrong this time. Our investigation is in the wrong direction. Now, I think, the murderer must have multiple people, and what is the motive of the murderer, perhaps, this is the key to solving the case."
I looked at Xiao Liu, and I didn't have an accurate answer in my mind at the moment. I said slowly: "In this case, we will investigate separately. I have never seen this kind of team committing a crime! A team, if there is no common Interests and goals cannot be gathered together! The murderer will definitely not be more than one person."
Xiao Liu and I shook our heads at the same time.
Guan Zengbin coughed, and then said: "I don't understand psychology, and I will give you a point from the perspective of forensic science. The reason why the murderer made the steel bar like this may be because he wants the victim to die quickly. On the other hand, such steel bars can save effort."
"Save your energy?" We looked at Guan Zengbin.
Guan Zengbin nodded, and said seriously: "That's right, Gu Chen actually mentioned something just now, because when a person is alive, muscles will contract. When a knife penetrates the body, it may be contracted tightly by the muscles." It wraps around the body, creating a strong pressure and clamping the knife. This is why, sometimes, the organs can maintain their original shape for a long time when the knife is pierced into the body without being pulled out."
After speaking, Guan Zengbin pointed to the blood groove on the steel bar again, and said: "The blood groove on the steel bar is very deep. After piercing, the muscles can't fit tightly to the steel bar. There is a gap in the middle, there is air, and strong pressure It does not exist, so as long as you stab it quickly, you can stab it to the end. In this way, the strength required will be less."
This is indeed a factor, but I don't know how much less this strength will be under this kind of factor, and whether the murderer's strength is just within this range. And this uncertain factor is that Xiao Liu or I will believe this. I believe in this, a thin murderer can do it, but Xiao Liu obviously doesn't believe it.
Guan Zengbin looked at the two corpses, then at the few of us beside him and said, "Don't say anything, let's separate the corpses first."
Gu Chen and I dragged a corpse to separate the two corpses, which is a testament to the song, Love even if you die.
Guan Zengbin looked at the two corpses and started a simple autopsy, while I looked at the room. Judging from the condition of the house, this bedroom is not small. People who enjoy it have relatively large bedrooms. This is what Sister Mao told me before, and this Zhou Yufeng looks like a person who can enjoy it.
There is a screen on one side of the room, about 1.5 meters high. If the murderer is hiding here with steel bars, it is not impossible.
There is only one thing, the hostess will not come to look behind the screen, otherwise, judging from the male corpse's height and figure of 1.8 meters, it is more than enough to deal with a murderer who is 1.7 meters tall and thin. In other words, the murderer concluded that the hostess would not come here, which meant that the murderer had come to the hostess' house more than once.
I closed my eyes, imagining the picture of the murderer killing someone.
At this time, Guan Zengbin said: "Judging from the appearance of the two corpses, there is only one penetrating wound on their bodies."
Guan Zengbin pointed to the wound for us to see: "There are a lot of traces of life in the wound, which means that this is a fatal injury. The cause of death is estimated to be organ failure caused by excessive blood loss, but it is difficult to make a conclusion before the autopsy .Inferred from the stiffness of the corpse, etc., the time of death was around ten o'clock last night."
"Ten o'clock?" Everyone asked.
Guan Zengbin nodded seriously, and said, "Don't be surprised. Although there is no autopsy yet, the time is not too far away. In other words, the murderer is the child who went to the top floor to kill the man and woman after killing the couple."
I asked, "Have you investigated the child's situation? When did he disappear yesterday?"
One of them took a step forward and said to me: "We asked the neighbors around, and they said that this kid went out to play yesterday afternoon and didn't come home until seven or eight in the evening. Gao Ze usually likes to play, but when it's time I went home, and I never go home after dark. The parents came to look for it, but they couldn’t find it. It was around ten o’clock, and they were in a hurry.”
"Then everyone in the building was looking for it." He scratched his head and said, "Some people just thought it was children who ran away for fun. Anyway, they searched for a long time, but no one called the police."
At ten o'clock, the man and woman died.
If my guess is correct, at this time, the boy has been controlled by the murderer. The boy might have heard his parents shouting for him, after all, he was on the second floor, but this couple didn't care whose child was lost, and only wanted to discuss the great harmony of life.
He continued to say to us: "These people kept looking for them. When it was past one o'clock, some people said that the child might have fallen asleep at Lao Wang's house. Because Lao Wang is a kind person, those children always give some delicious food when they go, so Those kids like to pester Old Wang."
"So some people went to Lao Wang's house on the second floor to look for Lao Wang, and some people were still looking for him below." He looked outside the window and said, "When they came in, they saw Lao Wang hanged himself. It happened to be broken, Lao Wang fell down, and it seemed that the fall was not easy. At the same time, that Gao Ze also fell from the upstairs, and the fall was terrible."
We all know the following situation. Later, Pharaoh and the child were sent to the hospital, but the child was too seriously injured and died.
What everyone didn't know was that the man and woman had died as early as ten o'clock. At this time, the murderer was always in the building, and there were people below, so it was absolutely impossible for the murderer to go down. If we analyze it from this point, that is to say, the child is already in the hands of the murderer.
I suddenly thought of a picture, the murderer was not alone behind the screen, but two people, the murderer and the child. Then, after killing two people, the murderer took the child up to the top floor.
No one would have thought that the child they were looking for was actually in the building, and now they were on the top of the building.
"Not good!" I said to everyone: "The murderer did kill according to the fantasy written by Lao Wang. Now the widow is dead, the child is dead, and the rest are the workers in the factory. If the murderer continues to kill , then it will definitely be done in the factory, and..."
"Besides, he was involved in the machine?" Xiao Liu said with wide-eyed eyes.
"That's right." I said, "Contact that factory immediately and send our people to check it out. The murderer will definitely show up there soon."
I turned to the others and said, "Take the body back, Guan Zengbin, you are in charge of the autopsy, and a few of us will go to the factory to have a look."
