Zhong Youhan and Xu Shuangyu understood.

Even Li Changbo understood: "Therefore, now it can only be judged that he died of suffocation." It is not yet possible to tell whether he killed or committed suicide—"

Fu Shi shook his head, gave him an approving look, and said in his heart: What a good seedling, it's a pity.

Immediately afterwards, Fu Shiyi asked Zhong Youhan to take a hand: "Look at the back of the corpse." ”

The corpse already had obvious corpse spots on its back, and it was connected into a large patch.

Fu Shiyi said softly: "According to common sense, corpse spots and small-scale zombie zombies appear in death for about half an hour to an hour, and when two hours or so, they are flake-like, each of them is not connected, and most of the zombies begin to appear. After about three hours, the corpse spots fused into large patches, corpse freezers appeared all over the body, and lips began to wrinkle. ”

Zhong Youhan immediately made a judgment: "The corpse spots have been connected into a large piece, but the corpse stiffness has not appeared all over the body, and the lips have not begun to wrinkle, so what's the matter?" ”

Of course, Fu Shiyi also noticed this phenomenon, and immediately gave an explanation: "Because the deceased died of mechanical asphyxiation, the corpse spots appeared earlier, which is also one of the manifestations of mechanical asphyxiation death." The reason is that this acute asphyxia can lead to blood stasis, so it appears relatively early. ”

Zhong Youhan was stunned, and his mind suddenly coincided with the previous case, and then nodded thoughtfully.

Unconsciously, he looked at Fu Shiyi's gaze, which was also more solemn.

Fu Shi looked at the corpse spots on his back and said conclusively: "The corpse spots are deposited on the back, indicating that they have not been moved after death, and this is the scene of the first crime." ”

Xu Shuangyu still remembered the previous question: "Then was he injured before he died, or was he injured after death-"

Fu Shiyi coughed: "Then this involves a new knowledge point." ”

Fu Shiyi stretched out his hand and pointed to the bloody place: "You take a closer look at the wound." ”

Zhong Youhan didn't care about the smell of the top, so he took a closer look.

Fu Shiyi pointed to the edge of the wound: "The wound will have a contraction, rolling, and life reaction, which means that it is a prenatal injury." It's like if you usually hurt yourself, you will find that after a while, the wound will shrink a little by itself, whether it is skin or flesh, it is shrinking and aggregating as much as possible. For a longer time, the edges of the wound will be red and swollen, and even light yellow transparent water will emerge to help scab over. ”

"All of this is caused by the fact that the wounds of a living person will heal on their own. That's why it's called a life reaction. If you have this reaction, you are still alive. ”

"On the contrary, if the wound directly presents a gap-like pattern without the slightest sign of contraction, it means that it was caused after death."

Zhong Youhan has already made a judgment: "This wound should have been caused before his death. The whole flesh is shrinking. And the blood has flowed so much-"

Fu Shiyi nodded with relief: "Yes, there won't be a lot of blood flow after death." Because after death, the blood no longer flows, and even if it bleeds from the wound, it is only because there is still blood accumulated in that place. ”

So the amount of bleeding is limited.

Xu Shuangyu gasped and felt incredulous: "How much does that hurt?" ”

Li Changbo had already thought deeper: "If such an injury was caused before his death, it means that the murderer must have wanted to torture the deceased." And...... How do you do it so that people don't scream in pain and fight back—"

Even if the people in this house are deaf and mute, it is not so bad that all the neighbors around them are dead.

It's so loud that the neighbors can hear it.

Fu Shiyi pointed to the skin lesions caused by strangulation and friction on the wrists and ankles of the corpse: "Because the deceased was tied up." ”

Fu Shiyi reached out again and gently broke the deceased's jaw, carefully observed the corners of his lips and oral mucosa, and then affirmed: "He didn't scream because his mouth was also blocked." ”

"People with their mouths gagged are not completely unable to make sounds, but they are definitely not very sharp and high-pitched, and they are not enough to spread far. Naturally, I can't hear it. ”

Fu Shi repeatedly repeated the fact: "Moreover, when there is a huge wound in the person, there is no way to scream again." It hurts so much that I can't speak, and this sentence is not a simple adjective. ”

Li Changbo frowned, his brows furrowed even tighter: "In this way, the murderer is very experienced. Tie up, don't resist, gag your mouth and don't let the other party call someone-"

"So, how did he tie up the dead? How did he get inside? ”

There is no need to answer this one, Li Hai can answer: "The door bolt is well placed, and there are no traces of knife scratches on it, so the door is not opened from the outside." And as soon as they pushed the door open, it can be seen that the murderer left through the door at that time. ”

"We've also seen the windows, and they've been open all the time in this weather, but there's no trace of foot on the lattice."

"Either you went in through the window, and the murderer was very skilled, so there was no trace left. Either that, or the deceased opened the door himself and let people in. Otherwise, the murderer laid an ambush in advance, waiting for the deceased to go back to the house to sleep. ”

Fu Shiyi echoed: "Li Hai's analysis is very correct. But at this point, we may be able to ask the deceased. ”

Fu Shiyi said it so carefully that at this moment, a sense of absurdity rose in everyone's hearts - everyone is dead, how can you ask him? How would he reply?

Thinking about it too much, it makes people can't help but feel a little chill in their backs.

Fu Shiyi quickly explained the secret to everyone: "Zhong Langjun, look at the back of the corpse's head and neck. ”

Zhong Youhan turned the deceased over, pulled his hair away, and looked at it carefully. Then shook his head: "There are no traces of beating." ”

"There are no marks on the back of the neck either."

Fu Shi nodded: "It doesn't seem that he was knocked unconscious." ”

Li Changbo thought thoughtfully: "So there are two possibilities left - one is that the deceased is willing, and the other is what kind of medicine was used to make people faint in the past-"

Fu Shiyi nodded happily: "Li County Ling is really smart. ”

Li Changbo's face was not obvious, but he coughed lightly: "It's just these two methods, but it's not easy to confirm——"

Fu Shi smiled: "Of course there is." ”

Li Changbo raised his eyebrows: "Then there is a little lady who pays for it." ”

Fu Shiyi gave him a "wrap on me" look: "The time of death should be after noon." There was still food outside the house, apparently having lunch. If you open your mouth and smell it, you will know if he drinks or not. If you don't drink, you won't get drunk and fall asleep. In today's weather, you don't need to take a nap at noon. Therefore, a big living person, when he is eating, or just after eating, and people come into the house, he will not be unaware. ”。

This passage is quite informative, and Li Changbo couldn't help but ponder it.
