Chapter 386 Profile of the Criminal Suspect
As soon as Zhou Ning's words came out of his mouth, several people all acted in unison, looking at Zhou Ning and nodding.

Seeing the expressions of the three people, Zhou Ning raised his finger and pointed to the X-ray of the lungs of the corpse on the chest, which was relatively complete and very clear, with some traces of dense silk mesh on it.

"The deceased had mild silicosis, that is, pneumoconiosis. This level is not serious. At her age, she may not have any symptoms at all. At most, she may have a cough when she has a cold.

However, during the pregnancy checkup, 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 way to search.

The deceased should have lived near polluted factories, or engaged in related occupations, and could be exposed to silica. This can also be used as a point of investigation.

In addition, when I just performed the autopsy, I found that the deceased had mild pulmonary edema, no fungiform foam in the respiratory tract, and not much exudate, which looked a bit like dry drowning, but there were a few dense nodules here, which 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 asphyxiation. The deceased had no head, hands or feet, but no resistance injuries on the body. He died 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 swollen due to high decay, the weight of the deceased was not high, between 120-125 catties. Of course, this is when she was pregnant. Between 155-160. "

Huang Detachment looked at Zhou Ning, nodded continuously, and took out a small notebook, and wrote down every word Zhou Ning said. After all, although he had never experienced these things, Zhou Ning's firm eyes made him have to believe everything.

"It's good to have a direction. We have contacted the hospital before, but there is no screening standard. We just collected all the information of all pregnant women who are about the same month, but the number is too large to call to confirm one by one."

Seeing that Zhou Ning had finished reading, Da Zhao quickly turned a page and said:
"I compared the temperature of the seawater. I think the temperature of the river water is similar to the temperature of the seawater. From October 10th to 20th, the seawater temperature of Qindao was very stable, always between 27-18 degrees."

As for the moat, the width of the river is 102 meters, and the depth is 5 meters. The bottom and embankment are built with stones. If there is a lot of sediment, it will be washed away when the gate is opened to release water. It is deeper than Liuhe River and Beijiao River.

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

"Cao Fayi, I have a question for you. What is the speed of the moat? Is it the kind of turbulent water? How deep is the water? Is there a dam around it?"

Zhou Ning nodded in satisfaction. Da Zhao now knows how to infer other cases from one instance, and tell him one thing. He can know your purpose and has already predicted the direction to search.

The southeast corner of the city hall square, this is exactly where the moat is close to the turn.

Cao Pingzhang quickly found a huge map of the urban area, hung it on another whiteboard, pointed to a blue line surrounding the urban area of ​​Dayao City and said:
"Dayao City is an old city. This moat existed in the Ming and Qing Dynasties. At the beginning of the founding of Huaguo, it became a stinky ditch. In the 80s, it was re-expanded and built together with the city wall of Dayao Ancient City. tourist attraction.

Cao Pingzhang suddenly realized that at this moment he understood the significance of Zhou Ning's reading of the map. He quickly approached the map and saw Zhou Ning doing some calculations on his mobile phone, and then said:

"I told you, don't be impatient. You are talking about something on this phone call. How do you arrange it for Team Huang? Be honest and listen here. Didn't my apprentice not profile the suspect? Wait for you to listen." After that, decide how to say it."

Zhou Ning nodded.

Weight between 120-125 catties;
fetal sex male;
36-40 weeks of pregnancy;
For patients with gestational hypertension and pregnancy-induced hypertensive syndrome, relevant examinations will be done in the hospital from August 8 to August 1;
Mild silicosis in the lungs, suspected living location, close to the factory that uses or produces silica in the processing process, of course, may also be engaged in related work;
Lung pulmonary edema, dense nodules, suspected mechanical asphyxia death;
Liu Yongxin stood behind Zhou Ning, looked at the autopsy characteristics of the deceased listed, nodded repeatedly, rubbed his chin and said in a low voice:
"In fact, once the characteristics of the deceased are inferred, some characteristics of the murderer can also be listed. Why don't you try to profile the murderer?"

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

"Do nothing for one thing, let Team Wu find someone to send it to Section Chief Cui. After all, they have done a lot, and they know what kind of test you want."

Then we push back 23.4 kilometers from the southeast corner of the city government square. Between the two points, whether there is a bridge along the river, it is unlikely that the body will be dumped on the bank. After all, the water depth needs to be sufficient. Shallow and easy to spot. "

"Boss, should this slice be sent to the local laboratory?"

Several people quickly tore off the equipment on their bodies, went to wash and left the dissection room.

Zhou Ning nodded. It seems that Cao Pingzhang is very familiar with the local situation, and on this map, the location of the salvage body parts is marked with a red pen.

As for the upstream, this water system belongs to the Liuhe River. A Xiashan Reservoir was built in the west of the city at the same time, and a sluice was built for the moat. The sluice was opened to release water during the dry season, and the water inflow was reduced during the wet season.

"The sunset time on the 26th is 17:09:44, and the sunrise time on the 27th is 6:10:11. According to this time calculation, the farthest distance for throwing the corpse is 23.4 kilometers. According to Cao Fayi, the flow direction of this moat is From west to east.

Zhou Ning nodded, and smiled at Huang Youdao. He understood this feeling too 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.

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

The entire moat forms a mouth shape to wrap around the ancient city, and the east side is connected to the Beijiao River. Therefore, from the Xiashan Reservoir to the Liu River, the moat, and the Beijiao River form a wetland landscape in Dayao City.

"Big Zhao told Big Sister Cui that Dayao City should pay the fee."

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

Cao Pingzhang widened his eyes, stared at the map, started from the square, reversed the scale, chose a position of 23 kilometers, quickly marked a few bridges, and then said:
"Based on this, the furthest we have reached is the section of the Liuhe River that comes out of the reservoir, but the river here is narrower. There are a total of seven bridges across the river. I will tell Team Huang to find out the monitoring of these seven bridges. As Director Zhou said, so many body parts are thrown into the river, it is indeed easy to be found on the bank, and it is also easy to run aground, and it is most likely to be thrown from a high place."

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 the ancient city of Dayao. October belongs to the dry season. It was September 10th. At this time, the river flow was very slow and the fastest was 27 m/s. "

Da Zhao fiddled with his mobile phone, and found the local temperature in a short while, and also specifically searched for the temperature changes around the city hall. The temperature here is slightly higher than that of Qindao. The temperature is between 16-20 degrees during the day, and the temperature at night Between 7-10 degrees.

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

The Huang Detachment patted Xiao Qu who came to the front, took people away without any nonsense, forensic doctor Cao had called people over, and cleaned up the body parts. As for various detailed sampling, including the inflammatory location of the lung suspected by Zhou Ning, Zou Jialong had Made slices.

Then this floating time will not be too long, I think it is the period from after dark on the night of October 10 to dawn on the morning of October 26, otherwise it would have been discovered long ago. "

"Big Zhao, check the temperature in Dayao City for the seven days before October 10th."

The corner of Liu Yongxin's mouth twitched twice. This precious apprentice of himself is good at everything, but he is a little picky, but this matter is indeed not Qindao's work, so he didn't say any more.

"Don't worry about Detachment Huang, first search for information according to this. If you have done a survey before, you can directly give the data to Xiaoqu and ask him to help with the screening. After all, he is from the laboratory. In terms of 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 corrupted and could still sink in the water. When the corruption gas was filled, the bag floated up and was discovered by the sanitation workers.

deceased woman;
Trunk and limbs, no obvious resistance wounds and abrasions, no traces of invasion;
Aged 20-24 years old;
Height between 155-160;

Zhou Ning glanced at the photos on the whiteboard and the vacant space beside him. Instead of rushing to profile the murderer, he turned around and looked at Cao Pingzhang.

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

According to the inflated state of the seven body bags in the video at that time, these body parts were discarded in the river for a long time. After the corruption gas was filled, they gradually floated up, and only then were sanitation workers discovered.

"What do you want to say? Team Huang and the others went to investigate, and we are idle too. Tell me about your profile, so that I can open my eyes."

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

Liu Yongxin grabbed the excited Cao Pingzhang and gave him a blank look.

Cao Pingzhang patted his chest, nodded towards Liu Yongxin, went to wash his hands, found a small medicine bottle from his pocket, opened it and took a pill, before returning to the group of people.

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

"Pfft, promising!"

Liu Yongxin shook his head with a smile, and the few of them didn't speak anymore, they all looked at Zhou Ning.
