Chapter 604 Is the old lady here?

Zhou Ning understood what Zhu Xingxing meant. She felt that these things were too complicated. It should not be the cutting done here, but the sacrifice here.

Before Zhou Ning could speak, Da Zhao had already moved over.

"Why are there so many nonsense, let alone 20 years ago, it was the 70s and [-]s. At that time, there were mobile service teams showing movies everywhere, with generators and movie projectors in the cars. This problem is easy to solve, but I suggest letting Chen Cheng Let’s take a look and see if these methods are the methods of a professional doctor.”

Liu Yufei rubbed her nose and called Chen Cheng before Zhou Ning could say anything.

"Don't wait outside, come to the No. [-] dissecting room, Zhou Ning wants you to distinguish whether the suturing and incision techniques are done by professional doctors, wear a mask at the door, and don't retch me when you come in What a shame!"

The last sentence, Liu Yufei turned around and said in a low voice.

Zhou Ning has moved out of the way, and the place where the mummified skull was opened has been covered with a middle towel. The cut skull and the piece of head skin are all placed in the tray. It's a doctor, and the corpse can be seen, but the irritation of the mummy is not something ordinary people can stand.

After a while, Chen Cheng knocked on the door and poked his head in. When he saw his daughter-in-law, he was about to laugh when Liu Yufei glared at him, frowned and waved his hands:
"Hurry up and take a look."

Chen Cheng ran in briskly, he knew exactly what Zhou Ning and the others got back, so he was very vigilant, walked to the dissection table, did not dare to look around, Zhu Xingxing had already placed the tray in front of him.

"Dr. Chen, please help me take a look. The figure-eight suture method seems to be difficult to see now. Do you have any opinions on the craniotomy tool? Considering these things comprehensively, do you think the person who did all this is the right person?" From a major?"

Chen Cheng glanced sideways, and he was relieved that his senses were fine.

"Don't worry, Doctor Zhu, can you give me a magnifying glass? I'll take a look and answer your question!"

Without needing Zhu Xingxing to go there, someone had already sent Chen Cheng a magnifying glass to observe it. Everyone was not in a hurry. Chen Cheng pulled the suture and let out a hey sound.

"Hey, this thread is a bit special. It is much thicker than the one we use now. I think it can be removed to check the material. After all, the seam has changed a lot after 2000. Since the end of the 80s, the standard of seam , the commonly used numbers in China are defined as 0, 1, 4, 7, 10, the larger the number, the thicker the line.

Moreover, the development history of sutures has also changed greatly, from bottled sutures in the 1940s to 1950s, to polymer sutures in 1958, and even PLA sutures in 1974. Anyway, each period has its own special Sex, I can't give you a date on this line.

However, it is definitely not what is used now. It is very tough, and it feels that it is very strong with the addition of composite materials. As for the method of opening the hole with the electric drill, at least one knows the method of craniotomy. "

Zhou Ning nodded. Sutures can be used for dating analysis. This is indeed a direction. After this, you can ask Sister Cui who is better at this.

He waved his hand towards Chen Cheng. Chen Cheng walked to the anatomy table. Following the direction of Zhou Ning's fingers, he saw the positions where the eyelids of the deceased were incised, and instantly understood Zhou Ning's intentions. Chen Cheng observed and stared round eyes.

"Give me a pair of gloves, the dead man's eyeballs are removed?"

Zhou Ning nodded, Da Zhao handed over the gloves, Chen Cheng put them on, Zhou Ning handed over two tweezers, Chen Cheng bit the bullet and opened the eyelids of the mummy, the eye sockets were empty and nothing could be seen.

"Professional enough, this removal of objects in the frame is very professional. If you are not a professional, you will not be able to achieve such a professional level, and at least there will be cut marks in the frame. Look here, I think it is a manual process. This person is definitely a professional doctor, or he often does such things, I don’t know if the butcher takes pig’s eyes like this.”

Da Zhao came over, shook his head and said:
"Butchers don't take raw pig's eyes. They usually take out the braised pig's head after it's cooked. After all, it will break if it's soaked in water."

As soon as this sentence was finished, Fang Dongsheng turned around and rushed out, Da Zhao blinked and spread his hands innocently, obviously saying, I didn't do anything, what's wrong.

Zhou Ning gave him a blank look, without talking nonsense, and waved his hand to signal that Chen Cheng could get out of the way.

"The dissection continues. Zhu Xingxing prepares the scalpel and chainsaw."

Chen Cheng had already run out, Liu Yufei glanced at it, and followed, Da Zhao slammed his mouth and swallowed the nonsense, after all, the recording equipment was turned on here, otherwise he would have to say something sarcastic.

Open the three chambers, take out the sternum and ribs, the hydration effect of the internal organs of the digestive tract is not good, they are all shriveled like dead branches, and fit on the back wall of the chest cavity, abdominal cavity and pelvis, and all these organs are taken out.

Zhou Ning analyzed it carefully, and a conclusion appeared in Zhou Ning's mind. He had done an autopsy of a mummy before, and the effect of hydration was not good, and there were residues in the digestive tract, but this seemed to have been cleaned thoroughly. Dry, with no residue of any kind.

Zhou Ning frowned, and carefully inspected the limbs of the deceased again, only to find that there were two cut marks on the bottom of the bracelet, which were not found when he checked the bracelet just now. After all, the cut marks were completely sealed after drying up. Bloodletting was performed here, but as one of the embalming measures.

Instructing Zhu Xingxing to take a sample, Zhu Xingxing cut the stomach and small intestine. Zhou Ning took a look. Although it was shriveled, there were still traces of bleeding on it, and there were spots of mottled ulcers. Zhou Ning took off the mask and gloves.

"Sun Gaotie stitched it up, and Zhu Xingxing recorded that before the mummy died, it fasted for a long time, and even underwent drug excretion or enema. There were cut marks on the inside of the two wrists, and the cut marks injured the arteries and veins. It was bloodletting, in preparation for the embalming of the corpse.

Let's sort it out. Except for the traces of the electric drill on the head and the suspension injury of the wrist, the mummy has no fractures. Before the sacrifice, it fasted for a long time and was excreted through enema or laxatives.

At first, I thought that the deceased was anesthetized and unable to fight against the struggle. Seeing the deep cut on the wrist, he should be bled first, and when he reached a certain amount of unconsciousness, he should be cut off eggs, gouged out his eyes, cut out his tongue, pulled out his teeth, opened his head, and poured mercury.

After doing this, the special medicinal powder is applied, and the fabric wrapped in the outer shell is placed in the required posture to hang and air-dry. We don’t know whether the sacrificial technique is professional or not, but all the cutting techniques and the selection of sutures are very professional. It should be Is a medical practitioner or professionally trained personnel.

The cause of death of the deceased was hemorrhagic shock, and the incorruption of the body was related to the above-mentioned operations. As for the time of death, the preliminary judgment is about 20 years, and the specific time depends on the identification results of sutures and wrapping materials. "

Zhou Ning waved his hand, Da Zhao turned off the recording equipment, Sun Gaotie had already finished suturing, the mummy was wiped clean, covered with a white cloth and pushed out, all doors and windows were opened, after all, a large amount of mercury was poured into the body of the deceased, even if the ventilation system was turned on, they It is also cutting the body of the dead, and part of it will still be volatilized.

Chen Cheng poked his head in at this time, and seeing that it was over, he trotted over.

"I checked, and according to the size of the craniotomy hole you mentioned, the drill bit of an ordinary electric drill M5 can be adapted, and it is not a specific tool.

In addition, I thought of something, if according to your analysis, this is a sacrificial activity 20 years ago, then how did you get this mercury?Although this is not a big child, the amount of mercury poured into each of eight children is still considerable.

A normal seven or eight-year-old child's brain weighs 1350 grams, and its texture is similar to water tofu. If according to your analysis, this child's brain is crushed and sucked out, filled with mercury, the weight difference will be large.

After all, the specific gravity of the brain is not much different from that of water. One cubic centimeter is about 1 gram, but the specific gravity of mercury is 13.59 grams per cubic centimeter. I don’t understand the difference, but it’s many times worse, right? "

Speaking of this, Chen Cheng retched, it was disgusting what he said, Zhou Ning understood and patted him on the shoulder.

"I understand what you mean. One person needs a few catties of mercury, and eight people need a larger amount. Doing tens of catties or even more than 100 catties of mercury at once is not a small amount. You can query it from this angle, right? ?”

Chen Cheng clapped his hands.

"That's what I mean, if you understand what I mean, Liu Yufei insists on not letting me say it."

Liu Yufei gave him a warning look, Zhou Ning waved his hand and said:

"Sister Fei, don't stop Chen Cheng. It's thanks to him this time. The autopsy here is over. Another mummy is soaking in Lufeier's solution. Do you want to ask Fang Da if that respected old lady brought up?

And the coffin is not to say that it can be transported down today. We also need to look inside. If we don’t find it, we still have to go to the site for a second survey. After all, we didn’t bring any tools last time. Whether it is the first site or not needs to be checked carefully. . "

Liu Yufei nodded, obviously agreeing with Zhou Ning's judgment.

"It is said that the old lady will be here soon, let's go to the front and wait. The office next door has just delivered a whiteboard. I found that it is the same as your office. It is double-sided. Let someone sort out the content of the anatomy. As for the next step , we'll talk after we finish talking."

Zhou Ning nodded and glanced at everyone.

"Zhu Xingxing took someone to sort out the autopsy records. You guys have a look at the temperature of Lufeier's solution, and help Zhu Xingxing to perfect the findings of the past few days, and see if there are any omissions we have left. Didn't Fang Da send some people over here?" Personally, I want to learn the trace inspection, Lao Yang, you can teach the basic knowledge, and then you can show up with us."

Zhu Xingxing told everyone to leave. At this time, Fang Dongsheng, whose face was pale, came back and nodded apologetically towards Liu Yufei and Zhou Ning.

"I'm sorry, I really can't hold back. There is a criminal case involving a dead person in our generation. It's a big deal. Forensic doctor Lao Zhang can't handle it, so I contact the provincial department directly and come to help. I really didn’t follow the autopsy.”

Zhou Ning shook his head.

"It's okay, this kind of professional can't stand it, we also hold our foreheads, by the way, Fang Da, is that old lady here?"
