Chapter 239 Cervical Dislocation
Liu Yufei raised her finger to point upstairs, and sighed helplessly, with extreme exhaustion in her voice.

"Upstairs in the laboratory, as soon as there is a case, our boss is like clockwork. He doesn't seem to know how tired he is, so I'll give you something when he's done. I'll find a place to rest for a while. The boss is following the above two Chatting with an economic investigation expert, it seems that some details have been found in the accounts."

Zhou Ning raised his eyebrows. Although he really wanted to hear it, he knew that what he was most anxious to do now was to go for an autopsy.

"Sister Liu can rest here. I'll ask someone to prepare for the autopsy, so that your boss won't come over later to remind you."

Liu Yufei smiled, lay down on the sofa, and closed her eyes.

Zhou Ning took off his coat, put on a white coat, and before he went out with the files in his arms, Da Zhao pushed the door open and came in, and saw Liu Yufei on the sofa at a glance, Da Zhao stared round his small eyes, covered his mouth, and pointed Ning, pointing at Liu Yufei.

Zhou Ning rolled his eyes at him, and went straight out the door. Da Zhao rushed to catch up, closed the door carefully, and whispered to Zhou Ning's ear.

"Tell me, why did you get hit so badly? You started to change your taste, like Yu Jiefeng? Let me tell you, Sister Liu is a Sanda champion. With your small physique, you can knock him down with just one finger. "

"What do you think about every day? Quickly ask Zhu Xingxing and the others if they have arrived."

Da Zhao shrunk his neck, and was relieved to see Zhou Ning so serious. As soon as he grabbed his phone, he saw Zhu Xingxing, Yang Xuetong, and Sun Gaotie going upstairs together talking and laughing.

Da Zhao waved his hand.

"I've saved the phone bill, so hurry up and go to prepare for the autopsy."

Zhou Ning raised his hand and stopped Sun Gaotie.

"Go to Sister Cui's place on the high-speed rail to check whether Cui Haibin sent blood samples for testing on February 2009-2, 14. The name of the deceased is Zhang Yinan. If found, ask Sister Cui to call all the tests of Cui Haibin in the past two days. As a result, I think this one will save."

Sun Gaotie hurried to the inspection department, Zhou Ning and the others went directly downstairs, Zhu Xingxing ran to inform the personnel in charge of thawing, and sent the body to the No. [-] autopsy room.

After several people changed their equipment, the corpse had already been brought in. The visitor pointed to the thin quilt on the corpse and said:

"Group leader Zhou, we didn't dare to touch the outer wrapping. After all, the ultra-low temperature freezing time is a bit long. I'm afraid that once it is opened, the skin of the deceased will also fall off, which will affect your judgment."

Zhou Ning nodded with a smile. Da Zhao had already embraced the man's shoulders. In fact, Zhou Ning just looked familiar and didn't know his name.

"Thank you, Xiao Huang, you still have experience."

Xiao Huang happily pushed the cart away, and Zhu Xingxing had already started X-ray scanning. Since No. [-] dissecting room was equipped with the helical scanner provided by the laboratory, they were able to quickly obtain three-dimensional images of all the bones of the corpse. This is much clearer and more accurate than simple X-rays.

After a while, the image of the deceased's skeleton appeared on the big screen. Zhou Ning moved the mouse to take a closer look. The fractures of the limbs and head were very serious. The right temporal part of the skull completely collapsed, and some fragments had fallen into the skull.

The bones of the limbs were not as simple as Cui Haibin's autopsy report mentioned. How to put it, they were basically broken into slag. In many places, the bones had completely pierced the skin, and the right ribs were all broken, piercing the lungs and heart.

This kind of injury can kill a person instantly. On the whole, the right side of the deceased has been smashed into a paste, the kind of flesh and blood.

When Zhou Ning zoomed in on the image, he found that the second and third cervical vertebrae of the deceased were misaligned, which is very common in the case of the deceased falling from a building.

However, her dislocation is a bit strange, it is a dislocation from left to right.

Zhou Ning closed his eyes and raised his hand to compare the posture of the deceased.

The deceased had the most fractures on the right side. According to the analysis of all fracture states, she landed on the right side first, with her right arm raised and her left arm blocked in front of her chest, her legs bent on the left side and her right leg straightened.

If you land in this state, even if the cervical spine is dislocated, it should be dislocated to the left, but now it is completely opposite.

Zhou Ning opened his eyes, and his face suddenly became serious. If he was just suspicious before, then now, just based on the dislocation of the cervical spine, he can conclude that Zhang Yinan's death was not as simple as suicide and falling from the building.

"What happened to Zhou Xiaozhou?"

Da Zhao noticed that something was wrong with Zhou Ning's gaze, so he hurried over.

Zhou Ning shook his head and waved to Yang Xuetong and the others.

"Go and prepare a watering can and physiological saline, 0.9% is enough, carefully wet the thin quilt, soak it all, and then peel it off."

As soon as this remark came out, everyone moved.

Not long after, Yang Xuetong came back with two plastic buckets, which were physiological saline obtained from the laboratory. Da Zhao took several watering cans that Zhu Xingxing found, rinsed and disinfected them, and began to fill them up one by one.

Afterwards, several people began to spray physiological saline on the thin quilt continuously. After waiting for about half an hour, Zhou Ning carefully lifted a corner of the thin quilt, and the deceased's feet could be easily separated, followed by the legs.

When I opened it, I found that there was a cloth bag on it, which contained the clothes and shoes of the deceased. It seemed that Chen Wenchi was more careful, and after tossing for a long time, the thin quilt was completely removed.

Several people breathed a sigh of relief. The full picture of the deceased Zhang Yinan had been revealed to everyone. The condition was well preserved. Chen Wenchi's method was still good, and it was also thanks to him asking a professional.

Da Zhao nodded towards Zhou Ning, turned on the recording device, and then began to introduce the identity of the deceased, the time of death and the details of the case.

As for the reason for the autopsy, he glanced at Zhou Ning, and directly said that the family members of the deceased requested it, which can be said to be watertight.

Seeing that he had finished speaking, Zhou Ning pulled over the magnifying glass with LED lights and carefully observed the facial injuries of the deceased, as well as the head. The right temporal part and part of the right face of the deceased had completely collapsed, which looked very scary.

Afterwards, Zhou Ning looked at the neck of the deceased and slightly raised the mandible. He could feel that the mandible of the deceased had also been broken. This action caused the face of the corpse to be lifted only to the left.

There were no bruises on the neck of the deceased, and there were no traces of pinching fingers. Zhou Ning frowned slightly.

Since the cervical spine is misaligned like that, and the neck is not pinched, how is it done?
In Zhou Ning's mind, there was a flashback of a deceased person who was abused at night. The child's cervical spine was also twisted, and the neck could not see pinches and strangulation marks, but behind the ears, there were four bruises on the occipital scalp. , the murderer hugged the dead man's shoulder from behind, grabbed the dead man's head with one hand and turned it quickly to the other side, causing the child's cervical spine to be completely dislocated.

The dislocation of Zhang Yinan's cervical spine at this moment is consistent with the child's state, and it cannot be caused by the same trauma caused by the fall.

Thinking of this, Zhou Ning did not perform an autopsy immediately as usual, but walked directly to the head of the deceased, and stretched out his hand towards Zhu Xingxing. Zhu Xingxing froze for a moment, and handed over the scalpel.

Da Zhao kicked Zhu Xingxing's shoe, kicked it to Yang Yang's chin, and then muttered a few words silently, before Zhu Xingxing realized that Zhou Ning was going to shave the dead man's head.

Seeing the flattened state of the head of the deceased, she trembled, and quickly handed over the razor, trying to concentrate herself.

Zhou Ning quickly shaved the deceased's head, and then used a huge bag underneath. The hair fell off one after another. After cleaning, he pulled over the magnifying glass with the LED light again, and carefully checked the position from behind the left ear to the scalp of the deceased.

There were no bruises or finger marks on the surface, and Zhou Ning frowned. He didn't think his judgment was wrong.

The strength to dislocate the cervical spine of the deceased is enough to leave traces. Is it because the injury time is too short, so the damage is not obvious?

Seeing Zhou Ning stop, everyone didn't dare to ask. At this moment, the door of the dissecting room was opened, and Xu Dayuan and Liu Yongxin walked in. Seeing Liu Yongxin tugging on Xu Dayuan's sleeve during the dissection, Xu Dayuan also stopped his voice and followed along. come over.

Zhou Ning raised his eyes, just in time to see Liu Yongxin, and nodded towards Liu Yongxin. Liu Yongxin came over and asked in a low voice:
"What's wrong, apprentice?"

"Master, according to the scan, I found that the second and third cervical vertebrae of the deceased were misaligned from left to right. This does not match the damage that the deceased could have caused by falling. I think that someone twisted the deceased's head vigorously, causing the damage. However, the left scalp and No finger marks were found on the back of the neck, could it be that the time was too short?"

Liu Yongxin didn't get close, instead he took half a step back and stared at the dead man's head, then returned to Zhou Ning's side, and said in a low voice:

"From a distance, it seems that there are horizontal scratches, but it is difficult to judge. You can cut it open and have a look. Sometimes the surface of the damage cannot be seen, and you can observe it through the subcutaneous layer. I think your judgment is correct."

Zhou Ning nodded vigorously, and was affirmed by Liu Yongxin. Without any further hesitation, he scraped the scalp and neck skin of the deceased with a scraper, handed it to Zhu Xingxing, and then cut open the scalp with the scalpel.

Pulling back hard, the scalp of the deceased was turned upside down, Xu Dayuan's eyelids twitched when he saw it.

Liu Yongxin and Zhou Ning both lowered their heads slightly and looked inside their scalps.

Sure enough, I saw three slight traces of subcutaneous hemorrhage on the inner side, and then turned it over to compare the positions. Zhou Ning drew the shape of subcutaneous hemorrhage with a pen.

Da Zhao hurried over to take pictures, and everyone was very excited. Finding this at least proves that Zhang Yinan did not commit suicide. As for who the murderer is, we don't know for the time being.

Zhou Ning breathed a sigh of relief and asked Zhu Xingxing to check the vulva of the deceased. He started a quick autopsy. The stomach of the deceased was empty, and the heart, liver, and intestines were punctured by ribs, and samples were taken from each place.

Zhou Ning tried many times and took out less than two milliliters of heart blood. The deceased suffered such a serious trauma and lost a lot of blood. It is extremely lucky to find such a little.

However, there was a scratch on the back of Zhang Yinan's right hand. This Zhou Ning was a little puzzled. After all, the place where it fell was the roof of the car. There was nothing rough here. Even if there was an injury, it was often cut or stabbed. scratches, as if scratched on the ground.

After handing Da Zhao the things that needed to be submitted for inspection, Zhou Ning recorded the cause of death and the injuries of the deceased one by one, and then Da Zhao turned off the recording device, and Xu Dayuan hurried to the front.

"Did the autopsy find anything?"
