"Then this person must carry a duffel bag that is not too small when he leaves! Just start with the amount of blood spatter, the murderer must prepare clothes, pants and shoes, and have a hat, otherwise it will not work!" Hua Ziqing nodded thoughtfully, "Oh, by the way, let me tell you a particularly interesting discovery." ”

Bai Xue looked at Hua Ziqing calmly, waiting for him to say what that "particularly interesting discovery" was, with her experience all along, this person and Xiao Geyan are the same, what they think is "interesting", and what others think is "interesting", there is absolutely nothing in common.

"On the bodies of the three deceased, we found multiple near-death injuries. Hua Ziqing said.

After finishing speaking, he paid attention to Bai Xue's expression, as if he wanted to see the surprise on her face, but after waiting for a long time, Bai Xue didn't have any special reaction, if he did, I'm afraid he was just waiting for his next step.

"Don't you think there's something strange about this near-death injury?" Hua Ziqing was unwilling, the feeling of throwing out a seal and the other party being able to catch it was much less fun than directly announcing the answer to the other party, "Think about the cause of death of these three people! Think about it carefully!"

Bai Xue thought about it along Hua Ziqing's train of thought, although the shopkeeper Tian Derun's family of three struggled and did not struggle, and the difference between being sedated and not being sedated, the cause of death was the same, they all underwent mechanical asphyxia and led to the final death result, according to the results of the on-site investigation, it is preliminarily presumed that they should have been suffocated to death after covering their mouth and nose with a pillow, and their heads were cut off within a short time after death.

The so-called near-death injury naturally refers to the fact that the time of the formation of the injury is just in the near-death state of the person, that is to say, when the victim suffers these injuries, at least from a biological point of view, has not completely lost his vital signs, but has already reached that critical point, and completely dies within a short time after the injury. Because when a person has just lost his vital signs, the blood will not stop flowing immediately, let alone cool and coagulate instantly, and there is a time lag in between, so if the body of the deceased is beaten at this time, it will be the same as before death, causing trauma marks such as subcutaneous bruises, but unlike the beating before death, the victim who is dying of death and injury has basically stepped into the threshold of death when he is beaten, and then the body temperature, Blood flow begins to decrease and slow, so the bruises from beatings can be easily distinguished from bruises and bruises caused before death.

Bai Xue didn't have much knowledge of forensic science, but she still had some grasp of this relatively superficial concept, Hua Ziqing asked him to think about it, and she naturally thought of this layer.

After thinking of this layer, she combined Hua Ziqing's special emphasis on the causes of death of the three deceased, and the form of being cut off and hung outside the gate later, and suddenly understood what Hua Ziqing was talking about by "interesting".

"How much hatred does the shopkeeper's family have with this murderer?" After Bai Xue understood, she also realized that there was something unusual in this, "This is after suffocating people to death, they are still angry, and they have to beat the deceased who just died again?" The murderer is a sedative, a tool for dismembering the body, and clothes and shoes that can be changed and covered, it is obvious that he came prepared, not a temporary crime, so that is to say, this murderer knows very well that after killing Tian Derun's family of three, he is going to saw off their heads and hang them outside the door to show the public, but under such a premise, the murderer still feels that Tian Derun's family of three is not enough to calm the resentment in his heart, so he has to beat the corpse again!"

"That's right! What those near-death injuries told me is such a mental journey of the murderer!" Hua Ziqing snapped his fingers, and finally felt satisfied, "Bai Xue, your understanding is reasonable, otherwise, it would really be a waste of Teacher Xiao's guidance to you!"

I know that Xiao Geyan's little fan brother is uncomfortable when he speaks without a little bit of content about Xiao Geyan, but what Hua Ziqing said is also an indisputable fact, Bai Xue has made very obvious progress in many aspects since she worked with Xiao Geyan, so there is nothing worth refutating.

Especially now, thinking of what the NDE means behind it, Bai Xue's brain cells have also been activated, and her thinking has become very active, she thought about it and asked Hua Ziqing: "Tian Derun, a family of three, who has the most serious NLD injury? Who is the lightest? Can you see it during this autopsy?"

"Yes, I was about to tell you this!" Hua Ziqing nodded, "Among the three people, the one with the most injuries on the body is Shi Hongying, the wife of the shopkeeper Tian Derun!

Bai Xue shook her head: "If you told me this immediately after I just figured out the identities of these three people at the beginning, I might have been really surprised, but now I can figure out some of the problems involved." Originally, I thought that a family of three was wiped out, the old two were in their sixties, not young, and did not have any bad records, but the sons of the two of them, in their twenties, have a lot of bad records, large and small, so people will have a preliminary impression that their family is because their son offended people outside, so it attracted the initial impression of killing, but if you think about it carefully, it is not difficult to find that this assumption is untenable. ”

"The murderer came prepared, obviously after some planning, and in this plan, there must be a plan to make the person who really caused this murder as the target have no chance to escape. And if Tian Derun and Shi Hongying are not the people who really want to take revenge, but they are just implicated, then it makes no sense that Tian Xueyi, who is the target, did not eat a meal containing a lot of sedatives, but drank a lot of wine and ate food completely different from his parents. The most reasonable explanation for this is that Tian Xueyi was not at home originally, he went outside to get drunk with others, and then went home, and the murderer did not seize the opportunity to drug him. In this case, although the final result of a family of three is that they all die of the same cause, which one of them is the most seriously injured on the body, which is obviously the one that the murderer hates the most and is most likely to be murderous. ”
