"The victim was male, aged between 20 and 25, fully dressed, with a large amount of vomiting stomach contents attached to the surface of the clothing, but the buttons of the clothing were intact, the belt was fastened, and there were no obvious mechanical injuries on the surface of the body.
A cramped rental house with a total area of no more than 30 square meters.
Under the architect's "exquisite" design, a bedroom and a living room, a kitchen and a bathroom are also completely demarcated.
However, with the necessary furniture such as beds, cabinets, tables, chairs, etc., there is not much room left to move around.
It's just such a small room, but at this moment it is crowded into four people, or three criminal policemen plus a corpse.
The corpse was lying on the bed, but half of his body was crooked, as if he was struggling to crawl out but couldn't do it, and his expression was a little hideous, which showed that he was not peaceful and painful.
There was a large iron basin next to the bed, which contained a large amount of charcoal that had not yet been burned.
Yesterday was the day of rent collection, but the tenant of the room did not appear for a long time, the old landlord came to check under suspicion, but found that the tenant was half lying on the bed, looking very scary, frightened she quickly reported the case.
At this moment, the on-site trace examination has been completed, and the forensic doctor Zhou Qianxin is squatting beside the bed, doing a detailed on-site autopsy.
The detachment leader Yu Chen frowned, glanced left and right, and said: "There is no damage to the corpse surface, and there are no traces of struggle at the scene, so the possibility of violent death can be ruled out."
"Do you need to talk about this" Zhou Qianxin pointed to the charcoal basin not far away, glanced at the corpse's face again, and said: "As soon as I entered the door, I smelled the smell of sour vomit, mixed with a strong smell of alcohol, and the corpse's lips were obviously cherry red, and there was a charcoal basin on the side. ” "Obviously, there could be three causes of death: alcoholism, carbon monoxide poisoning, and mechanical asphyxia caused by vomit inhalation into the trachea."
As she spoke, she picked up her camera and took a few pictures, then removed the body's clothing and took two more pictures of her abdomen and back.
Immediately afterward, she handed the camera to the police officer next to her, inserted the anal thermometer into the victim's body, and placed the thermohygrometer on the table, and began to carefully examine the body table: "The victim had a shallow abrasion on the left arm, elbow and the outside of the left leg, and there were no other mechanical injuries, which can be presumed to be caused by an unsteady fall after drinking."
"Eyelid edema in cadavers is one of the classic signs of alcoholism; In addition, the mucous membranes of the cheeks, lips, and mouth and nose are cherry red, which is typical of carbon monoxide poisoning.
In addition, there is still a small amount of vomit left in the victim's mouth, and it is unknown whether it choked into the trachea. ” "The corpse spots are mainly on the back and lower limbs, and they are also cherry red, so I am more inclined to think that the victim died of carbon monoxide poisoning.
In addition, the acupressure of the corpse spot does not fade, indicating that the liquid stained by hemoglobin has infected the tissue cells to make them colored, which is the infiltrating stage of the corpse spot. ” "The muscles of the corpse reached its peak of muscle rigidity, the cornea was completely clouded and the pupils were not visible, and the lower abdomen was corpse green."
Speaking of this, she glanced at the anal thermometer and the thermohygrometer before continuing: "The room temperature is five degrees, the relative humidity is seventy percent, and the anal temperature is consistent with the room temperature. ” "According to Newton's cooling rate, taking into account factors such as the fatness and thinness of the corpse, combined with the comprehensive consideration of corpse spots, pupils, and zombie stiffness, the time of death of the victim should have been 24 to 36 hours ago."
Yu Chen snorted and asked again: "Can you rule him out of killing?"
"Judging from the examination of the corpse alone, it can't."
Zhou Qianxin said: "Although homicide poisoning is relatively rare in practice, it is a common method for high-IQ organized murder crimes.
The cause of death in this case is not yet known, which is even more complicated: suicide, homicide, or accidental death are all possible. ” "For the rest, we have to look at the results of the examination at the trace department."
Yu Chen bumped the director of the trace examination department standing next to him with his elbow and said, "Cheng Wei, isn't the on-site trace examination already over, why haven't you kept talking?"
"Team Yu, this case is weird."
Cheng Wei smiled bitterly: "The scene is very clean, except for a little of the victim's vomit next to the bed, and his own shoe prints, there are no other traces."
The fingerprints are all fixed, but you can't let me use the naked eye to identify them, besides, according to my experience, these fingerprints are estimated to be the victim's own. ” "In addition, none of the victim's belongings in the family were lost, and the mobile phone, wallet, and computer were all there, so the possibility of murder for money could be ruled out in the first place.
Moreover, the windows of the room were closed and locked, and there were no signs of the door locks being picked or violently damaged. ” Yu Chen narrowed his eyes: "According to your meaning, this case is a suicide case" "No, on the contrary, I think it's a homicide case, a typical case of murder in a closed room, and the murderer's modus operandi is not clever, but it is very strange."
Cheng Wei shook his head and emphasized the word eccentric again.
"What do you say" Yu Chen became serious.
"First of all, the victim's belongings were not lost, but the room key was missing; Secondly, according to the landlord, when she came to the door, the security door was locked, of course, the key was locked.
Cheng Wei said: "These two points are enough to determine the nature of the case: he killed." ” "Are you worried that the victim will wake up and escape and cause the murder to fail, so take away the key and lock the door" Zhou Qianxin turned around and said with interest: "The method is indeed not clever."
That, what's the weirdness?"
"In the room, apart from the fingerprints that have not been examined, there are only traces left by the victim himself.
And I can be sure that the killer did not clean up the scene.
Cheng Wei said solemnly: "According to the law of material exchange in Luoka, as long as you enter and leave the scene, including us criminal police, you will consciously or unconsciously leave traces at the scene. ” As he spoke, he pointed to the ground: "Team Yu, Xiao Zhou, you see, the air environment around here is not very good, and the victim obviously doesn't pay much attention to environmental hygiene, there is a thin layer of ash on the ground, even if we are all wearing shoe covers, it will leave a clean area on the ground." ” In other words, as long as the perpetrator passes by the scene, no matter what means he uses, he will definitely leave footprints.
But alas, I checked carefully and found nothing. ” "This" Yu Chen and Zhou Qianxin glanced at each other, and they couldn't say why.
Seeing this, Cheng Wei smiled bitterly and said, "I've been thinking about this just now, but I can't figure it out. ” "That's it."
Yu Chen said: "I first asked people to block the scene and sent people to visit and investigate nearby.
Lao Cheng, you immediately go back with the fixed fingerprints and footprints and hand them over to the technical team for comparative inspection.
Xiao Zhou, you take the victim's body and Lao Cheng back together, and prepare to autopsy "Punishment and Murder
