Huang Xiaotao called the police, took Huang Mao away, and then the fingerprint readers took fingerprints at the scene and fixed them. 80 percent of the fingerprints at the scene were yellow wool, which added a lot of difficulty to our identification.

I went into the bedroom, opened the deceased's QQ on my computer, and looked at her friend list and group, this person is undoubtedly someone in the S-M circle.

But there were limited clues on the computer. I looked around and asked Huang Xiaotao: "Did you find the cell phone of the deceased?"

Huang Xiaotao shook his head.

Sun Bingxin and I went to the bathroom again. I carefully checked the ground with the pupil of the hole. Unfortunately, my footprints were trampled by yellow hair. Then my eyes fell on the sink on the side, and I crouched down and unscrewed the pipes. Bing Xin fetched a basin and continued.

Some dirt and hair accumulating in the pipes flowed out with the sewage. I searched carefully, but found nothing, and asked Sun Bingxin to get a pair of scissors, cut the pipe open, and investigate the inner wall.

On the inner wall of the pipe, I actually found some blood stains, and the amount was quite large. I said, "Extract it to see if it is the dead."

The on-site forensics process was quite complicated. Sun Bingxin and I first brought the corpse and the fruit knife of the weapon back for inspection. Huang Xiaotao stayed here temporarily. Back at the municipal bureau, I had a postmortem examination in the bone marrow after a long absence. I turned on the ventilator and changed the air, and with Sun Bingxin, I carried the body bag containing the body to the iron bed.

The deceased was about twenty-five years old, with a thin body and medium size. The time of death, combined with the corpse characteristics and the confession of yellow hair, was about forty-eight hours ago.

I opened the autopsy umbrella to examine the entire body of the deceased, and found no useful traces, because the deceased was touched and turned by the yellow hair after the death, and the sun marks have been seriously damaged!

Then I listened to the viscera of the deceased with the bones of the dead. There was empty sound in the atrium of the deceased because of severe ischemia, blood loss, and a certain degree of atrophy of various organs. It seems that the cause of death was indeed a cut on the wrist.

In addition, there is no damage left by external forces, or organ disease.

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

One more thing, I cut my wrist with a knife myself, and finally the downward trend will turn downwards, but the wound's upward trend is upwards, which makes me a little suspicious!

I subconsciously compared the thickness of the deceased's left and right hands. Her dominant hand was the left hand, but there was a shallow trace on the left wrist. I asked Sun Bingxin to come and see.

We discussed for a long time and came to a conclusion that the trace was pressed by a sharp weapon, and the shape was similar to a fruit knife.

I wondered, "It's strange. Did the deceased forget that he was left-handed, first pressed the knife with his right hand on his left hand, and then remembered that his dominant hand should be left hand, and replaced with a left-handed knife to cut his right wrist? "

Sun Bing said, "So, is it murder?"

I nodded: "There is such a possibility. Huang Mao just said that the blood had flowed to the ground, which made me a little suspicious! Why do people who commit suicide by cutting their wrists sit in a bathtub filled with warm water because warm water can relieve pain? At the same time, the blood flow is accelerated, and the body will be very cold during the blood loss process. Therefore, warm water is needed to cover the whole body, so that the suicide person can pass away peacefully in the drowsiness. In the film and television works, the suicide person is often seen sitting in the bathtub Here, the hand stretched out on the edge of the bathtub looks particularly beautiful. In reality, this is not the case. Generally, suiciders will dip their hands into the water and dye the whole tank of water into a bright red. Even if the suicider has no experience, the kind of cut-skinned The sharp pain will also drive him to do so. "

"Do you mean that the murderer just made reference to the film and television and botched the illusion of suicide?" Sun Bingxin suddenly realized.

"That's it!" I answered.

"I'm not refuting you. I think of another situation. The deceased is a girl. Girls love to watch TV shows. Maybe she is also affected by film and television dramas, and she is not so 'professional'?"

Sun Bingxin always has a large brain hole, but the viewpoints put forward this time are very realistic and I have not considered them.

I said, "It's possible, let's continue the test. If this is really murder and fake suicide, it will definitely leave other clues ..."

"Good!" Sun Bingxin started helping me right now.

I retrieved the skull pillow and listened to the skull of the deceased, and accidentally found signs of bleeding in the skull. So I took a look at the deceased's long hair and examined carefully, and found that there was a softer skin on the left scalp and there was congestion under the skin.

I stroked it with my hand, it felt like it was caused by a blunt object, but it didn't look like it.

In order to verify, I need to do a simple experiment, I said to Sun Bing: "I'll buy two honeydew melon, you'll wait for me here."

"Hami melon? Experiment?" Sun Bingxin was completely confused.

"Smart!" I laughed.

"Then I will take this time to send a blood sample to Technical Bryant to check it." Sun Bing said.

I suddenly thought of something and shouted, "Wait a minute! Remember the hair found by the last deceased? Compare it with that too."

I went out. This was the first time I went to buy props halfway through an autopsy. The main reason was that it was too late.

I came to a nearby supermarket and bought three honeydew melon. The shape of the honeydew melon is close to the skull, and there is a layer of grid on the surface, similar to the arachnoid under the skull, which can simulate the human head well.

The artificial works will also be tested to verify. Of course, the props we choose are relatively grounded. In order to verify the difference between burned and burned, the ancestor Song Ci used to test live pigs and dead pigs, and recorded them in the "Laundering Record" "in.

After returning to Bone Bone, I fixed the honeydew melon on a special rack, and then picked up a claw hammer and smashed it. The force should not be too big, but the melon did not have a hard skull.

After being dropped, the melon skin sinks radially into a piece, and some melon juice flows out, much like pure skull injuries commonly seen.

I said to myself: "The injury of the deceased was obviously not caused by a blunt device. I suspect it was caused by a blunt device wrapped with a soft object. Let's try it again."

I fixed the second melon, wrapped a thick layer of cloth on the claw hammer, and smashed it. The area of ​​the force became larger due to the cloth, but the 'injury' was still obvious.

Sun Bingxin asked: "Will it be rubber? Just like the soft rubber hammer used in construction, although it is soft, it will be concussed if it is hit **** the head."

"Try it!"

I do n’t have a rubber hammer here, so I wrapped the claw hammer with a piece of tire leather, and then hit the third honeydew melon. Under the action of the rubber, the hammer bounced back, and the honeydew melon slightly sunk, but it was not too obvious .

I lowered the hammer, cut the melon skin with a knife, and said excitedly: "Look, although the surface is not obvious, the 'soft tissue' below has been greatly impacted and 'swelled'. It seems that the weapon is a soft hammer."

From this point of doubt, this is undoubtedly a murder!
