The Underworld Detective

Huang Xiaotao called the police, took the yellow fur away, and then the tracer extracted the fingerprints at the scene and fixed the photograph. Eighty percent of the fingerprints at the scene were yellow fur, adding a lot of difficulty to our identification.

I walked into the bedroom, turned on the deceased's qq on the computer, looked at her friends list and the group, and this person was definitely someone in the s-m circle.

But the computer had limited leads. I looked around and asked Huang Xiaotao: “Did you find the victim's cell phone? ”

Huang Xiaopeach shook his head.

Sun Bingxin and I went to the bathroom again. I carefully checked the floor with the eyes of a hole. Unfortunately, the footprints had been trampled down by yellow hair. Then my gaze fell on the sink beside me, and I squatted down and unscrewed the pipe, and let Sun Bingxin fetch a pot to follow.

Some of the dirt and hair that accumulates in the pipe flows out with the sewage. I searched carefully, but found nothing. I asked Sun Bingxin to get a scissors, cut the pipes, and investigate the inner walls.

On the inner wall of the pipe, I actually found some blood, quite a lot of it, and I said, "Pull it up, see if it's dead. ”

The on-site evidence collection process was complicated. Sun Bingxin and I took the body and murder weapon fruit knife and went back for examination. Huang Xiaotao stayed here for the time being. Returning to the city bureau, after a long time in the bone survey dorm, I switched on the ventilator and changed the air, and with Sun Bingxin brought the body bag containing the body to the iron bed.

The deceased was about 25 years of age, thin, moderate in size, time of death, combined with a corpse characteristic and yellow hair confession, about 48 hours ago.

I held up the coroner's umbrella to examine the entire body of the deceased, and found no useful marks, because the deceased had been touched and flipped by yellow hair after his death, and the marks on the sun had been severely damaged!

Then I listened to the internal organs of the deceased, and the void in the heart of the deceased, because of the severe ischemia, because of the loss of blood, and some atrophy of the organs, and it seemed that the cause of death was indeed a cut on the wrist.

Besides, there is no damage from external forces, or organ lesions.

I checked the fatal wound again, the knife was very neat, I felt it was left by a sharp knife, I picked up the murder weapon and checked it against it, the wound matched, but I always felt that the knife was cut too deep.

One more thing, I cut my wrist with a knife, and eventually the tension will go down, but this wound will go up, which makes me a little suspicious!

I subconsciously compared the thickness of the victim's left and right hand. Her usual hand was her left hand, but there was a shallow mark on her left wrist. I asked Sun Bingxin to look at it.

We talked for half a day and came to the conclusion that the trace was pressed out by the sharp instrument and was similar in shape to the fruit knife.

I wondered, "This is strange. Did the deceased forget he was left-handed, pressed the knife on his left hand with his right hand, and then remembered that his customary hand was supposed to be the left hand, then the left hand grip knife, to cut his right wrist? ”

Sun Bingxin said: "So it's murder? ”

I nodded: “It's a possibility, just yellow hair said, the blood is bleeding all over the place, which makes me a little suspicious! Why do people who cut their wrists and commit suicide sit in tubs filled with warm water, because warm water relieves pain while accelerating blood flow and makes their bodies very cold during the blood loss process, so warm water is needed to wrap their bodies and leave the world calmly in a coma sleep. In film and television works, suicides are often seen sitting in the bathtub, reaching out to the edge of the bathtub, which is particularly beautiful. In reality, this is not the case. In general, suicides dip their hands in the water and dye the whole tank of water into a bright red. Even if the suicide killer is inexperienced, the sharp pain of cutting his flesh drives him to do so. ”

“You mean the killer just referenced the film and television, badly articulated the image of suicide?” Sun Bingxin suddenly realized.

“That's it!” I replied.

“I'm not disputing you. Oh, I'm thinking of another situation where the deceased is a girl, and the girls love to watch TV shows. Maybe she was also affected by TV shows, so she didn't kill herself so ‘professionally'? ”

Sun Bingxin has always had a relatively large brain hole, but the points raised this time are realistic and I did not take them into account.

I said: "There is such a possibility, let's continue the test. If this is really murder and forgery of suicide, it will definitely leave other tracks...”

“Yes!” Sun Bingxin began to help me now.

I took the pillow to listen to the victim's head, and accidentally found signs of bleeding in the brain. So I peeled off the victim's long hair and carefully examined it, and found a piece of skin on the left scalp that was soft and had bruises under the skin.

I touched it with my hand, and it felt like a blunt object or something.

To verify, I needed to do a simple experiment, and I said to Sun Bing, “I'm going to buy two hamamelis, you wait here for me. ”

“Hammeres? Experimental?” Sun Bingxin was misty.

“Smart!” I laughed.

“I'll send the blood samples to Tech at this time to compare.” Sun Bingxin said.

I suddenly thought of something, and I said, "Wait! Remember the hair we found at the last victim's place? Compare that with that too. ”

I went out, this was the first time I went to buy props on my way to the autopsy, mainly too late at night, I don't worry about Sun Bing going out alone.

I came to a supermarket nearby and bought three hamamelis, shaped close to the skull, and the surface had a mesh, similar to the arachnoid membrane beneath the skull, which mimics the human head well.

The work will also be tested and verified. Of course, the props we chose were relatively grounded. In order to verify the difference between burning and burning, the ancestors Song Zhi had tested live pigs and dead pigs and recorded them in the "Cleansing Grievance".

When I got back to the skeleton dorm, I fixed the hammered melon on a special shelf, and then I picked up a hammer and smashed it on top. Naturally, the force couldn't be too great, and the melon didn't have skull stiffness.

After the crushing, the melon peel dramatically slipped into a piece and some melon juice flowed out, resembling a common skull trauma.

I said to myself, "The injuries of the deceased were obviously not directly caused by a blunt instrument, which I suspect was caused by a blunt instrument wrapped in software. Let's try again. ”

I fastened the second melon and wrapped a thick layer of cloth around the hammer. Due to the effect of the cloth, the area of force became larger, but the 'injury' was more obvious.

Sun Bingxin asked: “Could it be rubber? Just like the soft rubber hammer used in the construction, though soft, it also gives you a concussion when you hit it hard on the head. ”

“Try it! ”

I don't have a rubber hammer here, I wrap the horn hammer tight with a piece of tire skin and smash it into the third hammered melon. Under the rubber action, the hammer bounced back, and the hammered slightly into it, but it wasn't too obvious.

I put the hammer down, cut the melon peel with a knife, and said excitedly: "Look, although the surface is not obvious, the ‘soft tissue' underneath has been hit hard and ‘swollen’ up, it looks like the murder weapon is a soft hammer. ”

In the light of all this doubt, this is murder!
