Chapter 31 What do you need a skull for?

Four 10 minutes later, in the dissecting room.

The X-ray film has already been taken, and the one who ran away screamed fast, as if being chased by a dog.

Zhou Ning and Forensic Doctor Liu were neatly dressed and stood beside the dissecting bed. At this time, the wrappings on the deceased's body had been removed, and the rope around the neck had been cut, revealing the whole body of the corpse.

On the upper body was a navy blue sweetheart-neck sweater with white stripes, a shirt of the same color, and underneath were brushed sweatpants and sneakers. Zhou Ning removed all the clothes and put them on the car beside him.

This attire is a bit nondescript, very formal on the top, but too casual on the bottom, but if you say he is a construction worker, it feels a bit awkward no matter what.

However, Zhou Ning couldn't tell what was wrong.

After looking through it carefully, all the brands of the clothes are not well-known, and the quality of the shirts is the best, but the logo on the neckline has been cut off, and there is a logo embroidered on the breast pocket, which is a golden ancient key standing upright, Zhou Ning Never seen such a trademark.

Forensic doctor Liu began to check the corpse form, talking intermittently about the discovery, and Zhou Ning made relevant records.

"The groove of the neck is leathery, and fibers of green nylon rope can be found in the skin damage. There are three turns of the groove around the neck [1], and there is a U-shaped groove from above the Adam's apple to under the ear.

The corpse was soft, and no resistance wounds or subcutaneous bleeding were found on the body surface. When it was discovered, the deceased was lying on the right side with his knees curled up, but the corpse spots [2] were concentrated on the back. The deceased was moved to the scene when he died for more than 36 hours. As for The time of death is 7-10 days. "

Zhou Ning wrote vigorously, and according to what Liu Yongxin said, he kept marking on the form recorded in the corpse form.

"Okay, let's do the autopsy!"

Zhou Ning paused, and Liu Yongxin followed him all the time today. He thought that the autopsy would have to be performed by himself, but since he was asked to do it himself, Zhou Ning was really not afraid. After all, there is no shortcut for this job, it depends entirely on experience accumulation, and he must do more .

No nonsense, Zhou Ning put on another layer of gloves and began to dissect.

They all knew about the anatomy. The first thing to check was the neck of the deceased. Zhou Ning cut the leathery skin with a sharp knife.

Separated layer by layer, Liu Yongxin took pictures at the side, and completed all the work in more than two hours.

Zhou Ning let out a breath, and Liu Yongxin raised his chin.

"You say I record, like I just did."

After sorting out his thoughts, Zhou Ning knew that Liu Yongxin was going to train him, so he said quickly:
"The deceased's thyroid gland, laryngeal mucosa, pharyngeal mucosa, tonsils and tongue base may have obvious congestion and focal hemorrhage.

The position of the U-shaped groove is relatively high, the large horn of the hyoid bone is fractured, and the lower three grooves are fractured due to violence. Combined with the X-ray film, the spinous processes of the third and fourth cervical vertebrae are fractured, and the murderer is very powerful.

The face of the deceased was severely chopped, with defects from the left lip to the cheek. The cuts overlapped with as many as 32 knife wounds. The nasal cartilage fracture showed signs of healing. It is suspected that the deceased had trauma about one month before his death.

The left ventricle was dilated, the wall thickness was about 1cm, and the valve was normal.Microscopically, a few fusiform scars can be seen beside the myocardial interstitial vessels.There was fluid leakage in the alveolar cavity of both lungs, and the deceased had rheumatic myocarditis with left heart failure.

During the autopsy, all internal organs were checked, and no trauma was found. As for the brain, Master, I have never done this. "

Forensic Liu put down the camera, and calmly handed over a razor.

"The identity of the deceased is unknown, and he died in such a tragic manner. A craniotomy is necessary. Come on, as a forensic doctor, shaving your head is the most basic job. Everyone has the first time."

Zhou Ning took the razor, without any resistance, and quickly shaved his head. He really didn't worry about it. After all, he shaved his grandfather's hair. The old man has no other hobbies, but he likes to be bald. Watching Zhou Ning's movements , Liu Yongxin smiled directly.

"It's fine, you kid. I knew that you would have had your head shaved in the Giant View last time."

Zhou Ning shivered, that kind of touch is really unforgettable in his life. I have heard people say that shaving the head of a giant is like shaving soft tofu.
Liu Yongxin had a smirk on his face, and was very satisfied seeing Zhou Ning's expression.

"Don't dawdle, cut and peel quickly, I will draw the position for you, and you cut the skull."

Zhou Ning is not talking nonsense. At this time, you have to satisfy the sense of control of the person who taught you knowledge. If you should behave cowardly, you should behave cowardly. If you have not responded, how can you satisfy the teacher?

This experience was also seen by Zhou Ning on Weibo a few days ago. Among other things, Liu Yongxin's smile just now showed that this point of view is very powerful.

With the powder splashing under the chainsaw, Zhou Ning completed the craniotomy and cleaned the surface. The two stared at the dead man's skull and saw the blood clot on the left side without turning it over. The amount of bleeding was about [-] milliliters, which was enough to kill.

Liu Yongxin took off his gloves with satisfaction, let out a long breath, and waved towards Zhou Ning.

"Okay, let's sew it up quickly, and then prepare the samples for inspection. There are a lot of things, you take your time, I will take a step first."

Zhou Ning had a question mark on his face.

"Master, what are you doing?"

"I went for an autopsy report, and the death was due to mechanical asphyxiation."

After speaking, Liu Yongxin changed his clothes and left.

Following the last sentence, the first question of whether to submit an advanced task appeared on the transparent display screen in front of Zhou Ning?

Zhou Ning was not surprised. After clicking submit, there was still no other response, but the countdown stopped at 2:12, and the journey took only 10 minutes. Zhou Ning was satisfied with this speed.

After the last injection, the surface of the corpse was wiped clean. Looking at the slash on the face of the deceased, it was temporarily impossible to recover.

However, Zhou Ning paused when he thought of the recovery technique he had been practicing so hard recently. If he had no idea, why not give it a try?
It's just this skull, how do you get it?

After Zhou Ning washed his hands, he went straight out of the autopsy room. Zhao Xinli was waiting in front of the door. When he saw Zhou Ning coming over, he thought he wanted to ask about the inspection.

"I asked Xiao Liu to drive to the city. I heard that these test results will be very slow. It's almost the end of the year. The city is also very busy with the backlog of cases. Shall I send you back to the team?"

Zhou Ning glanced at the time, it was already one o'clock, and he got into the car without talking nonsense. There was a lunch box on the co-pilot's seat, which was wrapped in a police uniform coat, Zhou Ning smiled.

"Thank you, you left me a meal."

"Thank you, in our line of work, you can only work when you are full. Hold your lunch box and let's go back to eat."

Speaking of starting the car, Zhou Ning returned to the office and saw Liu Yongxin sitting in front of the computer, slowly poking on the keyboard with two index fingers. At this speed, typing [-] characters before leaving get off work is considered speeding.

"Master, let me fight!"

Liu Yongxin waved his hand.

"You eat first, I will practice."

Zhou Ning gobbled up the boxed lunch. The old rules contained vegetarian dishes, but it was past the meal time, and the Wu Zang Temple was comforted in this way, and it was very comfortable.

After washing his hands and rinsing his mouth, Zhou Ning walked in front of Liu Yongxin. Liu Yongxin didn't talk nonsense this time, so he stepped aside, put the mirror aside, and rubbed the bridge of his nose.

"Okay, come on, it's too hard for me to find letters."

Zhou Ning took over, Liu Yongxin was talking, his fingers were flying, and he kept typing on the keyboard. In less than half an hour, the entire report was sorted out, and then printed out. Liu Yongxin read it again, and then let Zhou Ning upload and send it To Xu Dayuan.

Just after sending, Xu Dayuan's call arrived.

"Liu Forensic Doctor, do you have any intuitive findings, or can you give a description of the suspect based on the autopsy?"

Zhou Ning didn't speak, and listened carefully. Liu Fayi sat down and said slowly:
"Although the autopsy has been completed, Xu Da, don't be embarrassing. Everything has to wait for the test results. There are not many inferences that can be given now. As for the suspect's tracking direction, I can give two points:
First, the murderer was very strong, right-handed, strangled his neck with a nylon rope, not only fractured the hyoid thyroid cartilage, but also showed signs of fractures in the spinous process of the cervical spine;

Second, I suspect that the murderer knew the deceased and was still very hostile. The deceased had 32 slashes on his face, and his left cheek was missing flesh, which had been chopping with a knife all the time.

Thirdly, regarding the identity of the deceased, I still suspect that the deceased was a person engaged in outdoor work. As for the exact identity of the deceased, I will not know until the test results come out. "

Xu Dayuan hung up the phone without saying anything else, Zhou Ning hesitated for a long time, and looked at Liu Yongxin.

"Master, the identity of the deceased has no direction now. I have an idea, but I need the skull of the deceased."

Liu Yongxin was taken aback.

"What do you want a skull for?"

PS:【1】Three turns: one circle means one turn.

[2] Corpse plaques: the formation of corpse plaques is due to the cessation of blood circulation after death, and the blood in the cardiovascular system lacks power and accumulates in the lower parts of the corpse along the vascular network. , the capillaries and small veins in the lower part of the corpse are filled with blood, and the dark red to dark purple scars appear through the skin. These scars are cloudy and stripy at first, and finally form flakes, which are corpse spots.

Corpse spots are one of the earliest corpse phenomena, usually appearing 2 to 4 hours after death, and develop to the highest level after 12 to 14 hours, and will not transfer after 24 to 36 hours, and continue until the corpse is putrefied.
