Qi Yuan slowly paced into the bedroom.

Yan Zhongxin is taking his assistant and two trainee forensic doctors to do a detailed investigation.

He quickly spotted Qi Yuan, looked up, and said, "Yo, Xiao Qi, here." ”

"Director Yan," Qi Yuan said hello, and relayed the information he got from Wu Cheng's mouth to him.

"Did you die between five and six p.m.?" He glanced at the corpse and said, "It is close to the time of death deduced from the information obtained from the corpse examination, such as the temperature of the corpse, the distribution and character of the corpse spots, and the degree of stiffness." ”

Qi Yuan asked again: "Director Yan, can you see how he died?" ”

"Mechanical injury, respiratory failure, or hemorrhagic shock, it can be." Yan Zhongxin raised his chin and said: "He was hit by seven knives and two knives in the chest, which is estimated to have caused hemopneumothorax, and may also puncture the aortic arch."

Four stabs in the chest, one of which most likely punctured the liver. You should be aware that the liver is one of the most important blood banks in the human body, and the rupture of the liver itself may cause the immediate death of the victim due to traumatic shock, or the massive internal bleeding caused by the rupture of the liver, which may also cause the deceased to die of hemorrhagic shock......

Judging from the temperature of the corpse, the temperature of the victim's corpse is lower than that of the corpse under normal temperature and humidity, obviously the amount of blood loss is not small, and the probability of death from hemorrhagic shock is relatively large.

However, this is not of much significance, judging from the autopsy, there is only one perpetrator, and no matter how the deceased died, it actually has no effect.

The knife used is indeed a dagger, and it is impossible to tell whether it is the victim or the murderer. But there is one point, the dagger is not sharp, it is quite blunt, although it can also kill, but to achieve this level, the murderer's strength is not small. ”

Qi Yuan silently wrote down this clue.

Then he asked, "Are there any traces of a fight at the scene?" I looked, both the living room and the bedroom, it wasn't too messy......"

"Yes, but it's not obvious, and the victim shouldn't have much room to resist." Yan Zhongxin shook his head and said: "I judged from the bloodstains and a few traces at the scene, the murderer should have pushed him to the bed, and then stabbed him in the abdomen with a knife......

Seven stabs, the victim gradually lost consciousness and soon died - during this time, the murderer may have kicked the murderer, and the murderer hit the wardrobe, but because the deceased was not strong at this time, he could not make any further movements, and the murderer pounced again.

The deceased also struggled and scratched on the murderer's body, but unfortunately it was cold now, and the clothes were thick, and he could not scratch the dandruff tissue from the murderer's body, and although the nails were slightly curled, only a little silky fiber could be seen from the cracks of the nails.

In short, from the body and the scene, no evidence can be found enough to directly point to the murderer for the time being, even after an autopsy, I am afraid there will not be many clues in this regard - Xiao Chai's side is not too promising to make a breakthrough, after all, you all know the physical characteristics of the murderer.

So, unless you're lucky enough to find biological evidence such as strands of hair left at the scene by the killer, ...... If you want to solve this case, the focus is on whether you can make a breakthrough from the interpersonal circle of the deceased.

If you are afraid, the murderer and the victim do not know each other, so it is a bit troublesome, and there is a high possibility of an unsolved case......"

"Probably not, right?" Qi Yuan pursed his lips and said, "There is no difference in committing crimes, and it is rare to enter the house." And if it was burglary and robbery escalated to homicide, the murderer did not take the victim's property, and in the end, it was Wu Cheng who came in with his accomplices and took away his mobile wallet and computer. ”

"Indeed, I just said that, in fact, the probability is very small, and there should be an acquaintance between the murderer and the deceased." Yan Zhongxin said: "In addition, you just won, those two thieves didn't see how the suspect entered this room?" ”

"Hmm." Qi Yuan bowed: "I'm also a little puzzled by this, although I didn't ask them how they squatted, but looking at their tone, plus even when the deceased entered the door and when the suspect left can be said clearly, think about it, at least at the door of this house, they are staring at it to death."

In other words, when the murderer enters the house, it is likely not to be a door. So, did he come in through a window? So why did he do it? Worried about hallways and gates being monitored? Wouldn't it be more obvious when he was five or six o'clock in the afternoon? The people downstairs could see it as soon as they looked up. ”

"Find a way to ask those two thieves how they squatted and watched." Yan Zhongxin said: "In addition, I also pay attention to the way the murderer enters the house.

Although I am not directly responsible for solving the case, only the autopsy, I still have a little experience after so many years. This experience tells me that these two points may become the key to solving your case. ”

"Hmm." Qi Yuan nodded lightly, indicating that he understood.

The room was not small, but there were many people, and it was inevitable that there would be some obstacles, Qi Yuan found that he really couldn't help much, so he said hello and left.

Outside the door, Su Ping and Brother Song were still at the end of the corridor, and they seemed to have lit a cigarette again. ”

"Nothing to discover yet." Qi Yuan shook his head, and then relayed what Yan Zhongxin said to Su Ping.

"It's only been a long time, and it's strange to have a harvest." Su Ping shook his head and said, "Don't be too anxious, you should understand this principle after being apprenticed for so long." ”

"I know." Qi Yuan said softly: "I just think that I have to do something......"

"What, who do you think we are?" Su Ping chuckled: "You have to look at how busy you are to think that you are doing something, even if it is just a blind work or even a help, otherwise you are a leader who is lazy and messing around?" ”

Qi Yuan scratched his head.

"Don't think about those who don't have it, move it for me when it's time to move, don't be lazy on the side, when it's okay, what do you like, it's okay to smoke on the side, no one will say anything about you."

"Got it." He should say a word.

Su Ping snorted, and looked at Brother Song again: "Why hasn't the landlord come yet?" Give it a call. ”

"I might as well go back to sleep." Brother Song said: "It's such a cold day, and it's a big night. ”

"Ask again," Su Ping insisted: "If you can come, we will wait, if you can't come, it doesn't matter if you ask him to come back tomorrow morning, let's not wait here and do other work." Anyway, tell him to give a letter. ”

"Okay, got it." Brother Song answered, put the cigarette in his mouth, then took out his mobile phone from his pocket, flipped through the call records, and then dialed a number.

"Hey, hello, I'm the ...... who just contacted you"
