As soon as Zhou Ning's words came out, several people unified in one action, looked at Zhou Ning and nodded.

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

"The deceased had mild silicosis, that is, pneumoconiosis, which is not serious, and at her age, she may not have any signs at all, at most she may have some cough when she has a cold.

However, when I do a physical examination during pregnancy, I should be able to find out whether this is related to death, I don't know, it should not be related to this to kill a pregnant woman who is about to give birth, but this is a good way to search.

The deceased should have lived near a polluting factory or had been in a related occupation and had access to silica, which could also be used as a point of investigation.

In addition, when I had just performed the autopsy, I found that the deceased had slight pulmonary edema, no mushroom-shaped foam in the respiratory tract, not much exudate, and looked somewhat like dry drowning, but there were several dense nodules here, which I suspected was an inflammatory reaction.

Combined with the pulmonary edema of the deceased, I gave the judgment that the deceased may have died of mechanical asphyxiation, the deceased had no head, hands and feet, but no resistance injuries on his body, and was already dead at the time of the dismemberment.

As for the height and weight of the deceased, I also estimated, although the deceased's body parts looked seriously swollen in a high state of decay, but the deceased's weight was not high, between 120-125 pounds, of course, this is when she is pregnant, and her height is between 155-160. ”

The Huang detachment looked at Zhou Ning, nodded constantly, and took out a small notebook and wrote down what Zhou Ning said word for word, after all, although he had never experienced this, Zhou Ning's firm gaze made him have to believe everything.

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

Zhou Ning nodded, and smiled at Huang Youdao, he understood this mood too well, knowing that there might be dead people here, but the number was huge, and this range could not be narrowed, which made people scratch their heads.

"Don't worry about the Huang detachment, search for information according to this first, if you have done an investigation before, you can give the data directly to Xiaoqu and let him help screen it, after all, he is a person from the laboratory, and in terms of computers, no one in Qindao City dares to compare."

The Huang detachment patted Xiaoqu who came to the front, and took people away without nonsense, Forensic Doctor Cao had already called someone over to clean up the corpses, and as for various detailed sampling, including the location of the inflammation in the lungs that Zhou Ning suspected, Zou Jialong had already made a section.

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

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

"Don't do anything, let Team Wu find someone to send to Section Chief Cui, after all, they have done a lot, and they also know what kind of test you want."

Zhou Ning nodded.

"Da Zhao told Sister Cui that the cost should be paid by Dayao City."

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

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

Back in the office, Zhou Ning sorted out all the findings in the dissection process.

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

deceased female;

trunk and limbs, no obvious resistance injuries and abrasions, no traces of surname invasion;

Age 20-24 years;

Height between 155-160;

Weigh between 120-125 pounds;

Fetal Sex: Male;

36-40 weeks gestation;

For patients with gestational hypertension and gestational hypertension, relevant examinations should be done in the hospital from August 1 to August 28;

Mild silicosis in the lungs, suspected to be living in a factory that uses or produces silica in the process, and may also work in the field;

pulmonary edema in the lungs, dense and dense nodules, and death by mechanical asphyxia is suspected;

Liu Yongxin stood behind Zhou Ning, looked at the autopsy characteristics of the deceased listed, nodded constantly, rubbed his chin and said in a nonchalant voice:

"In fact, as soon as the characteristics of the deceased are inferred, some of the characteristics of the murderer can also be listed, why don't you try to profile the murderer?"

Zhou Ning frowned slightly, in fact, he had some ideas in his heart, but there were still too few.

"There are some ideas, but because there is too little evidence, it is difficult to make a judgment, and I am afraid of misleading the Huang detachment in the direction of their investigation."

】

Without waiting for Liu Yongxin to speak, Cao Pingzhang had already approached and said first:

"What do you think, the Huang detachment and they went to investigate, we are idle and idle, talk about your profile, let me open my eyes too."

Zhou Ning glanced at the photos on the whiteboard, as well as the vacant space next to him, and did not rush to profile the murderer, but turned to look at Cao Pingzhang.

"Forensic Doctor Cao, I have a question for you, what is the speed of this moat, is it the kind of river that is very turbulent? How deep is the water? Is there a levee around? ”

Cao Pingzhang hurriedly found a huge urban map, hung it on another whiteboard, pointed to a blue line around the urban area of Dayao City, and said:

"Dayao City is the old city, this moat is in the Ming and Qing dynasties, at the beginning of the founding of the People's Republic of China, it became a stinky ditch, in the eighties, it will be re-expanded here and with the city wall of the ancient city of Dayao, built into a tourist attraction.

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

The whole moat becomes a mouth shape to wrap the ancient city around, and the east side is connected to the northern suburbs of the river, so from the Xiashan Reservoir to the Liuhe River, the moat, and the northern suburbs of the river, forming a wetland landscape of our Dayao City.

As for the width of the river surface of the moat, the depth is 5 meters, the bottom and the embankment are made of stones, there are many sediments, open the gate and release the water, it will be washed away, here is deeper than the Liu River and the northern suburbs of the river.

As for the flow direction of the river, it is also from west to east, just according to the height difference of the ancient city of Dayao, October belongs to the dry period, the first fifteenth day of the first month will open the gate to release water, and the date of the discovery of the body is October 27, the lunar calendar is exactly September 13, at this time the river flow speed is very slow, the fastest is 0.5 m/s. ”

Zhou Ning nodded, it seems that Cao Pingzhang is still very familiar with the local situation, and on this map, the location of the salvaged corpses is marked with a red pen.

The southeast corner of the City Hall Square, where the moat is approaching a bend.

According to the video at the time, the seven body bags were in an inflated state, and these body pieces were discarded in the river for a short time, and after being filled with rotten gas, they gradually floated up, and only then were they discovered by sanitation workers.

"Da Zhao check, the temperature of the seven days before October 27 in Dayao City."

Da Zhao fiddled with his mobile phone, and after a while, he found the local temperature, and also searched for the temperature changes around the city government, which is slightly warmer than Qindao, with a temperature of 16-20 degrees during the day and 7-10 degrees at night.

Seeing that Zhou Ning had finished reading it, Da Zhao quickly turned the page and said:

"I checked the sea temperature, I think the temperature of the river is about the same as the sea temperature, from October 20 to 27, the sea temperature in Kotoshi Island was very stable, it was always between 18 and 20 degrees."

Zhou Ning nodded with satisfaction, Da Zhao now knows to draw inferences from one another, tell him one thing, he can know your purpose, and he has already predicted the direction that needs to be searched.

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

"Apprentice, what you mean is that the time when the corpse pieces were thrown into the moat may have been earlier, and the corpses were not rotten at first, but they could still sink in the water, and when the rotten gas was filled, the bag floated up and was discovered by the sanitation workers.

Then this floating time will not be too long, I think it is the period between after dark on the night of October 26 and just after dawn on the morning of October 27, otherwise it would have been discovered long ago. ”

Cao Pingzhang came to his senses, and only then did he understand the significance of Zhou Ning's reading of the map, hurried close to the map, saw Zhou Ning calculate on his mobile phone, and then said:

"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, the farthest distance of throwing the body is 23.4 kilometers, according to Forensic Doctor Cao, the flow of this moat is from west to east.

Then we push back 23.4 kilometers from the southeast corner of the city hall square, between the two points, whether there is a bridge along the river, it is unlikely that the body will be thrown on the bank, after all, the water depth needs to be enough, and the locals should know that only the water on the shore is shallow and easy to be found. ”

Cao Pingzhang's eyes widened, stared at the map, started from the square and reversed the scale, selected a location of 23 kilometers, quickly marked a few bridges, and then said:

"In this way, the farthest has reached the section of the Liuhe River where the reservoir comes out, but the river here is narrower, there are a total of seven bridges of all sizes spanning, I will tell the Huang detachment now, and find the monitoring of these seven bridges, just like Director Zhou said, so many corpses have to be thrown into the river, and it is indeed easy to be found on the bank, and it is easy to run aground, and it is most likely to be thrown down from a high place."

Liu Yongxin grabbed Cao Pingzhang, who was a little excited, and gave him a blank look.

"I told you not to be impatient, you said something on the phone, let the Huang detachment be there, how to arrange it? Listen here honestly, my apprentice didn't write a criminal suspect profile, wait for you to listen, and then decide how to say it. ”

Cao Pingzhang patted his chest, nodded at Liu Yongxin, went to wash his hands, and then found a small medicine bottle from his pocket, opened it and ate a pill, and then returned to a few people.

"I'm a little excited, take the blood pressure medicine first, otherwise I'm afraid I won't be able to bear it for a while, come on, Director Zhou, you say!"

"Poof, out of breath!"

Liu Yongxin smiled and shook his head, and several people didn't speak again, and their eyes fell on Zhou Ning.
