As soon as Zhou Ning's words came out, several people made the same move, looking at Zhou Ning and nodding.

Seeing the expressions of the three people, Zhou Ning raised his hand and pointed to the screen. The X-ray of the lungs of the corpse on the chest was relatively complete and the picture was very clear. There were some dense mesh-like traces on it.

"The deceased had mild silicosis, which is pneumoconiosis. The degree is not serious. At her age, she may not have any symptoms at all. At most, she may have a cough when she catches a cold.

However, during a physical examination during pregnancy, you should be able to find out. As for whether this is related to death, I don't know. Being able to kill a pregnant woman who is about to give birth should not be related to this, but this is a good search method.

The deceased should have lived near a polluted factory, or been engaged in a related occupation, and could have been exposed to silica. This can also be used as an investigation point.

In addition, during the autopsy, I found that the deceased had mild pulmonary edema, there was no mushroom-shaped foam in the respiratory tract, and there was not much exudate. It looked a bit like dry drowning, but there were several dense and dense nodules here. I suspected

This is an inflammatory response.

Combined with the pulmonary edema of the deceased, my judgment is that the deceased may have died of mechanical asphyxia. The deceased had no head, hands or feet, but there was no resistance injury on the body, and he was already dead when the body was dismembered.

As for the height and weight of the deceased, I also made an estimate. Although the body of the deceased seemed to be severely swollen in a highly decayed state, the weight of the deceased was not high, between 120-125 pounds. Of course, this was when she was pregnant, and her height was between 120 and 125 pounds.

Between 155-160.”

Detachment Huang looked at Zhou Ning, nodded repeatedly, and took out a small book to write down what Zhou Ning said word for word. After all, although he had never experienced this, Zhou Ning's firm eyes made him believe it.

everything.

"It would be nice to have a direction. We have contacted the hospital before, but there is no standard for screening. We just collected information from all pregnant women of the same month. However, the number is too huge and we cannot call each one to confirm."

"Boss, do I need to send this slide to the local laboratory?"

Then the floating time will not be too long, I think it is the period from after dark on the night of October 26 to the dawn of October 27, otherwise it would have been discovered long ago."

Before Liu Yongxin could speak, Cao Pingzhang had already come closer and said first:

As for the moat, the width of the river is 102 meters and the depth is 5 meters. The bottom and the embankment are made of stones. If there is a lot of sediment, it will be washed away by opening the gate and releasing water. It is deeper than the Liuhe River and the Beijiao River.

Liu Yongxin glanced at Cao Pingzhang, waved his hand and said:

Seeing Zhou Ning finish reading, Da Zhao quickly turned the page and said:

"I checked the sea water temperature, and I think the river water temperature is about the same as the sea water temperature. From October 20 to 27, the sea water temperature in Qindao was very stable, always between 18-20 degrees."

Zhou Ning frowned slightly. In fact, he had some ideas in his mind, but they were still too few.

Cao Pingzhang quickly found a large urban map, hung it on another whiteboard, pointed at a blue line surrounding the urban area of ​​Dayao City and said:

"Dayao City is an old city. This moat existed during the Ming and Qing Dynasties. At the beginning of the founding of the People's Republic of China, this place became a stinking ditch. In the 1980s, it was re-expanded and connected with the city wall of Dayao Ancient City.

, built into a tourist attraction.

Zhou Ning nodded.

Several people quickly took off their equipment, went to wash up and left the dissecting room.

Weight between 120-125 pounds;

Fetal gender male;

36-40 weeks of pregnancy;

Patients with gestational hypertension and pregnancy-induced hypertensive syndrome will undergo relevant examinations in the hospital from August 1 to August 28;

Mild silicosis in the lungs, suspected of living in a location close to a factory that uses or produces silica during processing, and of course may be engaged in related work;

Pulmonary edema, high density and dense nodules in the lungs, suspected mechanical asphyxia death;

Liu Yongxin stood behind Zhou Ning, looking at the listed autopsy characteristics of the deceased, nodding his head, rubbing his chin and saying in a low voice:

"In fact, once the characteristics of the deceased are listed, some of the characteristics of the murderer can also be listed. How about you try to profile the murderer?"

Liu Yongxin grabbed the excited Cao Pingzhang and rolled his eyes at him.

Huang Detachment patted the song and walked closer. He took the people away without any nonsense. Forensic doctor Cao had already called people over to clean up the body parts. As for various detailed sampling, including the location of pulmonary inflammation that Zhou Ning suspected, Zou Jialong had already

Made slices.

deceased woman;

There are no obvious injuries or abrasions on the trunk and limbs, and no traces of invasion;

Aged 20-24 years old;

Height between 155-160;

Back in the office, Zhou Ning sorted out all the findings during the autopsy.

"Don't worry, Huang Detachment, search for information based on this first. If you have done research before, you can give the data directly to Xiaoqu and ask him to help screen it. After all, he is from the laboratory. Regarding computers, Qindao City can say

No one dares to compare.”

"Apprentice, what you mean is that the time when the body parts were thrown into the moat may have been earlier. At first, the body parts were not rotten and could still sink in the water. When the decaying gases filled up and the bags floated, they were discovered by sanitation workers.

The entire moat forms a mouth-shaped shape that wraps around the ancient city. The east side is connected to the Beijiao River, so from the Xiashan Reservoir to the Liuhe River, the moat, and the Beijiao River form a wetland landscape in Dayao City.

Zhou Ning nodded with satisfaction. Da Zhao now knows how to draw inferences from one example and tell him one thing. He can know your purpose and has already predicted the direction in which you need to search.

The southeast corner of the City Hall Square is where the moat turns.

After hearing Da Zhao's search results, Cao Pingzhang and Liu Yongxin also understood what Zhou Ning meant.

The corner of Liu Yongxin's mouth twitched twice. His precious apprentice was good at everything, but he was a little picky. However, this matter was indeed not Qindao's job, so he didn't say anything more.

Zhou Ning nodded. It seemed that Cao Pingzhang was very familiar with the local situation. On this map, the location where the body parts were salvaged was marked with a red pen.

Da Zhao fiddled with his mobile phone for a while, and soon found the local temperature. He also specifically searched for temperature changes around the city hall. The temperature here is slightly higher than Qindao. The daytime temperature is between 16-20 degrees, and the night temperature is between 16 and 20 degrees.

Between 7-10 degrees.

Cao Pingzhang suddenly understood, and now he understood the meaning of Zhou Ning's map. He quickly came closer to the map and saw Zhou Ning doing some calculations on his mobile phone, and then said:

"Forensic Doctor Cao, I have a question for you, what is the speed of this moat? Is it a very fast river? How deep is the water? Are there any dams around it?"

Then on one side, a table was drawn to piece together various known information about the deceased.

So let’s push back 23.4 kilometers from the southeast corner of the Municipal Government Square. Whether there are bridges along the river between the two points, it is unlikely that the body will be dumped on the shore. After all, the water needs to be deep enough. The locals should know that there is only water on the shore.

Shallow and easy to spot.”

"The sunset time on the 26th was 17:09:44, and the sunrise time on the 27th was 6:10:11. Calculated based on this time, the farthest distance of the corpse was 23.4 kilometers. According to forensic doctor Cao, the direction of the moat is

From west to east.

"What do you think? Detachment Huang and the others have gone to investigate. We have nothing to do. Tell me about your profile and let me open my eyes."

"Da Zhao tells Sister Cui that Dayao City will pay for the expenses."

Zhou Ning nodded and smiled slightly at Huang Youdao. He understood this feeling very well. He knew that there might be dead people here, but the number was huge and the scope could not be narrowed down, which made people scratch their heads.

According to the inflated state of the seven body dumping bags in the video at that time, these body parts had been discarded in the river for a long time. After the putrefactive gas filled up, they gradually floated up and were discovered by sanitation workers.

Cao Pingzhang stared at the map with his eyes widened. Starting from the square and working backwards according to the scale, he selected a location of 23 kilometers, quickly marked a few bridges, and then said:

"Calculating this way, the furthest point is the Liuhe River section that comes out of the reservoir, but the river here is narrower. There are a total of seven bridges across it. I will tell Detachment Huang now to find the monitoring of these seven bridges.

As Director Zhou said, if so many corpses are to be thrown into the river, it is indeed easy to find them on the shore and easy to be stranded. It is most likely to be thrown from a high place."

"One thing is nothing, the other is the master. Let Team Wu find someone to send it to Section Chief Cui. After all, they have done more and they know exactly what tests you want."

Zhou Ning glanced at the photo on the whiteboard and the empty space next to it. Instead of rushing to profile the murderer, he turned back to look at Cao Pingzhang.

As for the flow direction of the river, it is also from west to east, which happens to be formed according to the height difference of Dayao Ancient City. October is a dry season, and the water will be released on the first and fifteenth day of the lunar month. The date when the body was found was October 27, which is the right day in the lunar calendar.

It’s September 13th. At this time, the river water speed is very slow, the fastest is only 0.5 meters/second.”

"I told you not to be impatient. You just want to talk about one thing on the phone. How are the arrangements going to be made by the Huang detachment? Listen here honestly. It's not that my apprentice hasn't profiled the criminal suspect. I'm waiting for you to listen.

After that, decide how to say it."

"I have some ideas, but because there is too little evidence, it is difficult to make a judgment. I am afraid that I will mislead Detachment Huang and their investigation direction."

As for the upper reaches, this water system belongs to the Liuhe River. In the west of the city, a Xiashan Reservoir was built at the same time, and a sluice gate was built for the moat. During the dry season, the gate is opened to release water, and during the wet season, the water inflow is reduced.

"Da Zhao, please check the temperatures in Dayao City in the seven days before October 27."

Cao Pingzhang patted his chest, nodded towards Liu Yongxin, washed his hands, found a small medicine bottle from his pocket, opened it and took one pill, before returning to the others.

"I'm a little excited. I need to take my antihypertensive medicine first, otherwise I'm afraid I won't be able to handle it for a while. Come on, Director Zhou, tell me!"

"Pfft, come out!"

Liu Yongxin shook his head with a smile, and the others said nothing, all focusing on Zhou Ning.
Chapter completed!
