Chapter 385 The Age of the Dead

Da Zhao gave the three of them a look, with an attitude of hating iron but not steel.

"Can you do it? If you can't, don't watch it. Go back and watch the video later. It's still November. What if it's summer?"

The embarrassment of the three people was greater than the discomfort, but the nausea was uncontrollable. They all lowered their heads and adjusted their breathing. Zhou Ning stepped forward to help Doctor Cao, placing the corpses piece by piece on the dissection table.

Placed properly, Zhou Ning did not rush to look, but waved to Xiaoqu behind.

"Using the equipment we have assembled, first take a picture of the corpse."

Xiao Qu moved quickly. In fact, these things were done early in the morning. After the film was finished, the monitor in the dissecting room showed the status of each corpse. Zhou Ning looked up at the monitor.

The deceased had multiple linear fractures in his ribs. Looking at the location of the fractures, it can be concluded that this was the injury caused when the corpse was dismembered, not an injury during his lifetime.

There were no other injuries to the bones of the limbs and spine, which was consistent with Zhou Ning's initial guess.

Zhou Ning retracted his gaze and looked at the corpse with the fetus on the dissecting table. The skin on the abdomen of the deceased on the front had rotten blisters, but now it had ruptured and a network of rotten veins was densely covered.

Liu Yongxin moved closer, glanced at the fetus on the scale, the weight and the state of the fetus, Liu Yongxin thought about it and said:
"Do you think that the actual month of the fetus is a little bigger than it looks? Do you suspect that the deceased had a high pregnancy syndrome or gestational diabetes, so the fetus is stunted, or the fetus is too small?"

Zhou Ning didn't care about those people, and observed carefully, the transverse crest, transverse groove, pubic tubercle, lower end, dorsal edge, upper end of the bony tubercle, ventral slope, and the edge of the pubic symphysis, seven iconic positions Shape.

"Hurry up, my apprentice is looking for you!"

The inner peritoneum and uterus were considered complete, but they were cut at the bottom near the pubic symphysis, and there were tooth marks from tweezers on the cut. It seems that Cao Forensic Doctor collected the fetal DNA from here, but the fetus was not completely taken out.

During the X-ray examination, it felt that the fetus was eight or nine months old, but now seeing the original appearance of the fetus, Zhou Ning could conclude that the actual age of the fetus should be at least nine months, or even close to forty weeks.

This is not killing a chicken, this is a pregnant woman with a child, a large living person who can calmly divide a corpse and consider equality, which is creepy.

Zhou Ning nodded slowly, but the phone in Forensic Cao's hand had already been dialed, so he hurriedly said something and asked Team Huang and Team Wu to come in and listen. Intermediate mitigation accuracy is also somewhat higher.

Liu Yongxin glanced at the time, took Pang Tianhang and Zou Jialong over, took out the pubic symphysis, and washed them clean. These two people were selected by Zhou Ning himself. Among other things, this person's tolerance to smell is better than ordinary people. It was too strong, and with the pubic symphysis, both of them looked at the pubic symphysis curiously.

Cao Pingzhang was slightly stunned, but he didn't ask another word. He quickly took out his mobile phone, dialed a number, then walked to the door of the locker room, and started talking there. Da Zhao had already turned off the video recording function at this time.

In the last step, the uterine wall was gently cut open, exposing the fetus.

In the small black room, he had been trained for a month, and only the pubic symphysis was given to distinguish the age of the deceased, so it was not difficult for Zhou Ning. After looking at it, Zhou Ning raised his head.

Team Huang and Team Wu didn't urge them, Zhou Ningchao raised his hands apologetically.

They have all heard of these before, but Dayao City has handled too few major criminal cases. It can be said that there has not been one for many years. If there are any, they are all from the provincial department to set up a special case team.

Zhou Ning took the scalpel and started the autopsy one by one, carefully observing and analyzing the traces of muscle rupture and the shape left by the cut surface.

Before Cao Forensic Doctor finished speaking, Zhou Ning turned around, walked to the body of the deceased, found the upper abdomen, and distinguished it. The various parts of the digestive tract of the deceased were placed next to the body on the back of the lower abdomen. .

"Indeed, let's wait for the result."

Zhou Ning paused. A fetus that seemed to be fully developed, even though it was only nine months old, seemed to weigh a little too little. Could it be that the mother had some disease?
In his mind, when he was training in the small black room, he saw a case that made Zhou Ning suddenly realize that he looked up to find Cao Pingzhang. Liu Yongxin felt it and quickly pushed Cao Pingzhang.

The deceased was 36 to [-] weeks pregnant, so her pregnancy time was around early February to early March. Now that she is pregnant and has a child, she is very important, and almost no one does not go for a checkup. After the file is established, different checkups are generally done according to each month.

As for the other corpses, Zhou Ning checked the corpses one by one. The fractures of the dismembered corpses were very neat, the kind that were cut off against the joints. As for the ribs, it seemed that they were split horizontally with an ax or hatchet, otherwise it would Causes a linear fracture of the ribs.

Of course, with this action, it seemed that the smell of the dissection room had risen to another level. Wang Henjian was the first to rush out. Zhou Ning kept moving his hands, peeled off the fetus, put it on the side, and carefully inspected it. Fan.

Cao Pingzhang leaned over, and Zhou Ning hurriedly asked:
"Forensic Cao, I would like to ask, did you extract the inner blood of the deceased before?"

Not long after, the two walked in quickly, obviously they didn't leave at all.

"The blood sugar of the deceased was 16.7mmol/L. This value is quite high. I didn't even think about it at the time."

After waiting for a short time, Forensic Cao hung up the phone and ran over quickly, with a trace of surprise on his face, after all, the blood sugar test was very fast.

However, this value of 16.7mmol/L is really high enough even for postprandial blood sugar.

Zhou Ning nodded, and quickly stopped Cao Fayi who was a little excited.

Seeing Cao Pingzhang's surprised expression, Liu Yongxin folded his arms in satisfaction and looked at the dissecting table.

After all, before they came, they had already discussed the procedure. The pubic symphysis is the easiest part to judge the age of the deceased. It must be extracted first. After all, the vulva and vagina of the deceased have been sampled.

Pregnancy-induced hypertrophy and gestational diabetes screening are generally carried out at 24-28 weeks, that is, when the pregnancy is six to seven months old. Let’s push it backwards. Then this test will be done between August 8st and August 1th. of.

The two looked at each other and nodded seriously.

Zhou Ning also checked it just now, and found no trace of surname invasion. The deceased's skin was fair, and there were no obvious scabs or other characteristic marks on the torso and limbs. Even the scars from the vaccinia vaccine could not be seen clearly, which is very rare.

Liu Yongxin nodded, with hope on his face.

Cao Pingzhang was a little excited. He held up his notebook and paper, and wrote down all that Zhou Ning said just now.

Zhou Ning cut the umbilical cord, picked up the fetal body, and motioned to Da Zhao to bring the electronic scale. Zhou Ning put it on and checked the weight. The fetus was only 1980 grams.

On the film just now, the fetus is in breech position with its knees curled up and its hands folded over its chest. There is no bone damage, and everything is normal except for the breech position.

"Don't worry, I don't think Zhou Ning has finished."

"Don't be surprised, this kid has been cooperating with my precious apprentice for two years, and he is very skilled. He is just a trace inspector."

"Wait a minute, I'll take a look at the pubic symphysis of the deceased and try to give the age range of the deceased, which will be more conducive to your further search."

"I read the test report before, and there was no blood sugar test for the deceased. Since the heart blood was saved, I should contact the laboratory to do a quick blood sugar monitoring for the deceased. I want to know the blood sugar value of the deceased."

"From the appearance of the fetus, it has been fully developed, but the head circumference and weight are really a bit mismatched. I think the fetus should be close to full term. Let's wait for their inspection. This is very fast. If you can go in this direction Search, I think the search range can be much smaller."

"I have extracted the body parts. I did a post-mortem inspection, videotaped and took pictures, and took samples of each part for inspection. As for the blood in the heart, I can collect as much blood as possible. After all, I think that if the identity of the deceased is found in the next step, blood can be collected. Rather than not."

Da Zhao didn't shirk, and hurried forward, cleared his throat, turned on the video recorder, and began to introduce quickly, covering almost all the information that was said last night, and the various numbers and time points were very accurate.

Moreover, the deceased was an eight or nine-month pregnant woman, who could do it?
Zhou Ning raised his head slightly. It seemed that he wanted the answer, so he had to find the answer by himself during the autopsy process. After all, Cao Forensic Doctor did not check the sex of the fetus for the sake of caution, but only found that it was a male fetus in the DNA test report.

Cao Pingzhang, who was standing beside Liu Yongxin, kept nodding his head and gave Liu Yongxin a thumbs up. Liu Yongxin leaned close to his ear.

"The deceased was dismembered and thrown into the water. The corpse was in a state of high decay. According to the temperature and water temperature at the end of October, the deceased died around October 10. I personally think that the state of the fetus is close to 20 weeks. Based on your previous information Inference, then we can give a search range.

Putting his mind away, Zhou Ning told Da Zhao:
"Big Zhao makes an anatomical statement and turns on the video recorder."

I think Cao Forensic Doctor can contact Team Huang to check the time period of the major hospitals. When the hospitals are conducting obstetric examinations, screening for pregnancy-related hypertrophy and gestational diabetes, people with very high blood sugar index will be screened one by one. "

The facial features of the fetus are not too corrupt and deformed, but the blood vessel network on the body surface is very dark, and the facial features and limbs are not deformed, but the size of the fetus is really small.

Zhou Ning pinched the deceased's stomach, which was completely emptied, and checked up and down. There were not many intestinal contents, but the deceased's head was missing. This is really not easy to judge. Before the death, the deceased was gastrointestinal Empty or some food.

Liu Yongxin held the tray with the pubic symphysis in full bloom, dragged another intern Pang Tianhang, and the two went straight to the pressure cooker. Pang Tianhang was already stiff. Zhou Ning glanced at it. High-pressure treatment of the pubic symphysis, I am afraid that the legs will be weak.

The size of the body parts of the arms and legs on both sides is basically the same, and there is no unequal situation. To be able to achieve this split state, you must understand the anatomical structure and be calm.

Zhou Ning directly took the pubic symphysis of the deceased, and then glanced at Liu Yongxin. It was either a newcomer or a trace inspection. Forensic Cao Zhou Ning couldn't say anything else, but Liu Yongxin didn't talk nonsense, so he hurried over.

Zhou Ning smiled, it seems that the master still understands himself.

Just as he was about to turn around, he was stopped by Liu Yongxin.

"The deceased were aged between 20-24 years old."

"Director Zhou, are you sure?"

Facing the doubtful Huang detachment, Zhou Ning paused.

"Okay, of course I haven't finished talking yet, do you want to hear my thoughts on career inference?"
