Cheng Wei thought about it, he didn't analyze and reason out loud, he was really not good at it.
After a few lessons, he honestly only did his job, completed the trace investigation and gave a report, sometimes he couldn't help but discuss with others, but he just threw out an idea, and then more often listened, that's all.
Yuan Youchong continued: "Judging from the information I got last night, Liao Wenjue's family members have gone out to play, and he is alone at home, so it stands to reason that even if he is killed, there should only be one victim, where did the other deceased come from?"
"And if the deceased is He Rui, why is he here, what is the connection between Liao Wenjue and He Rui's disappearance?"
At this time, another trace inspector who had been silent suddenly muttered: "I'm curious, although this soup pot is big, but the mouth and neck are estimated to be slightly larger than this head, it's better to put the head in it, I'm afraid it's quite laborious to take it out, how could the murderer think of using this thing to make soup."
"Also, let's cook the soup, but when the soup is cooked, I haven't touched it."
As soon as these words came out, Cheng Wei shuddered a little.
After a while, he suddenly thought of something and said, "Hey, no, this is Liao Wenjue's home, and he himself was killed and his body was mutilated, which means that the murderer has someone else." ” "Thinking about it, after the murderer killed, it is too bold to cook at the victim's house, will we think too much, the murderer boiled this head, maybe it was just to destroy the corpse, not to eat" "I don't know."
Yuan Youchong shook his head: "It seems that the victim whose head was cut off and stewed in soup should not be very old, it may be the missing He Rui, of course, it may also be another child, because his face is seriously damaged, he can't be identified at present." ” "If it's He Rui, why he's here is also a question.
Why Liao Wenjue was killed, and what the murderer's motive was, we don't know at this time.
In short, there are still too few clues. ” "Don't worry about this for now, you can complete the trace inspection task as soon as possible and get the clues."
"Okay."
"I'll go and see if Xiao Zhou's work is finished."
Yuan Youchong said again: "If you can, I'll let her come over and have a look." ” "Hmm."
When he came to the living room, he saw Zhou Qianxin holding Liao Wenjue's head to check, so he squatted beside her and asked, "How is it?"
"The other corpse parts are still frozen, and they can't be taken down for the time being, and if they are taken violently, they will definitely cause some damage to the corpse parts, so they can only be slowed down for a while."
Zhou Qianxin said: "This head is separated from the glass baffle and is being checked. ” "Well, there is no pre-mortem damage found on this for the time being, and in addition, because the temperature of the refrigerator fresh-keeping layer is also quite low, ordinary methods cannot determine the specific time of death, so we can only roughly guess that it has been more than forty-eight hours since his death."
"I'm measuring the temperature of the refrigerator when it's working, and when I do, I'll make more specific inferences."
As she spoke, she put the head down and asked, "You came to me suddenly, is there something in the kitchen that you want me to help with, anyway, I have to wait for the other corpses to thaw, if necessary, I can go over and have a look." ” "That's good."
Yuan Youchong said: "Come with me to have a look, it's like this" When he walked to the kitchen, Yuan Youchong had already told her about the matter.
She walked over to the casserole, observed it for a while, then went directly to the casserole and sniffed it, and then flipped it over with a spoon to get a better look at the head inside.
Seeing this, Yuan Youchong and Cheng Wei both secretly admired that they were extremely experienced forensic doctors, so they could not change their faces.
You know, if you are an ordinary person, you may be a little nauseous when faced with an ordinary pot of broth that has been left for two or three days and has begun to spoil.
"This soup smells slightly pantothenic, it is estimated that it is bad, and in this weather, it should not take too long to cook it now, two or three days, but it is not far from the time when Liao Wenjue was killed."
"Well, the face is quite badly damaged, and including the swelling caused by high temperature destruction and long-term immersion in liquid, it is not easy to identify his original appearance, and it is not easy to take it out completely, if you want to determine your identity, I am afraid you will have to do DNA identification."
Cheng Wei asked strangely: "This head has been boiled, and DNA can still be detected."
"Absolutely."
Zhou Qianxin raised her eyebrows and said: "If you cook soup, it's not a pressure cooker, and the temperature won't exceed 100 degrees Celsius.
DNA has a certain stability, at this temperature, although the hydrogen bond will be broken and the double helix structure will disintegrate, but as the temperature slowly drops and cools, the hydrogen bond single strand will reunite and restore the double structure again. ” "All in all, it is quite difficult to completely destroy the DNA structure, even if the corpse has been burned at high temperatures, sometimes DNA can still be detected in bones such as the femur that are wrapped in very developed skeletal muscles, and in the pulp."
"Of course, after the death of the body, due to the collapse of the cell structure due to the autolysis of the cell, the DNA itself will also be destroyed, and this damage is also irreversible, but it takes a certain amount of time, and the time for DNA destruction and disappearance of different tissues is different, in addition to the effects of bacterial destruction."
Yuan Youchong waved his hand: "This question is more complicated, there is no need to explain it to us, in short, we know that it is enough to detect DNA from it." ” As he spoke, he pointed to the cupboard under the stove and asked, "Lao Chenggang said, there are still a few dishes in the cupboard, all of them are big meat, I guess they may have all spoiled, can you find out what kind of meat these are?"
"Uh" Zhou Qianxin took two steps back, squatted down to open the vegetable cupboard, glanced at it a few times, and said at the same time: "It's not difficult to check out what kind of meat it is, but if it's human flesh, it's not easy to determine whose meat it is." ” Yuan Youchong frowned: "Isn't it possible to test DNA?"
"It may not be able to be extracted."
Zhou Qianxin shook her head: "The temperature of frying and steaming is completely different, these meats are fried, and the temperature can easily exceed the threshold of irreversible damage to DNA structure. ” "Moreover, after all, the meat has been cut, and if you fry it for a long time, the DNA in the deep layers may also be destroyed, and you may not be able to detect anything."
"What's more, these meats have been completely spoiled, and they are not like the heads in the soup pot, and there are bones with very stable structures, and DNA can be detected even if they are completely spoiled."
"That's right" Yuan Youchong shook his head and said, "Anyway, let's pack it up and take it back for inspection first, and then make sure what kind of meat it is."
"Torture and murder :
