Criminal Investigation: Forbidden Rose

The first thing after discovering a corpse is always to confirm the source of the corpse.

The Forensic Center immediately ran a DNA test, but the autopsy was still scheduled for the next day.

At this moment, Yan Jingjing stood on tiptoe outside the dissecting room and looked around: "Leader, can we go in and take a look? Just a look! I, I, I haven't seen the view of giants yet, I want to take a look, and then I will go back to my classmates next time." Will brag hehehe!"

Xia Yi's face was dark: "No. You don't want to see it."

Yan Jingjing pouted: "But Deputy Jiang went in to see it!"

Shao Lin explained gently: "Deputy Jiang should have gone to see Director Yu, not the view of giants."

Yan Jingjing: "..."

After a person dies, the bacteria in the body multiply rapidly, producing a large amount of putrefaction gas, which makes the corpse swell into a "giant", commonly known as the concept of giants.This is the last corpse that a forensic doctor would like to encounter - not to mention the disgusting appearance, the unpleasant smell, and most of all, the severe decay will destroy a lot of evidence, thus increasing the difficulty of solving the case.Even if the efficiency is as high as Yu Min's team, they failed to give a result for a long time.

Finally, Yu Min changed her clothes and made a summary for everyone in the meeting room.

"Due to the liquid environment in the sewer, the decomposition rate of the corpse is greatly accelerated. We believe that the time of death was 4 days ago, that is, May 5."

Shao Lin raised his eyebrows. He remembered that Yan'an had the first thunderstorm this summer that evening.

"The internal organs of the deceased have been autolyzed, so no valid information can be provided, but extensive compound fractures were found on the deceased, the most serious being the lumbosacral area, spreading up and down to the spine and long bones of the lower limbs. The fracture wounds showed traces of hematoma under the microscope , it can be judged as a fracture during his lifetime. Therefore, it can be ruled out that it was caused by throwing the body and falling from the building after death, or colliding in the sewer. The shape of multiple fractures and fractures conforms to the same external force, and it is difficult to be formed by human blows. Therefore, this fracture should be Falling or hitting from a high place, the lumbosacral area is the first force-bearing surface, and the cause of death is likely to be internal organ rupture caused by severe trauma."

"Unfortunately, the damage to the body surface and internal organs can no longer be further screened."

"Could it be that the inspection well had no cover, and she accidentally fell in? It wasn't raining at the time, and she fell in the dry well? Then it rained, and the person was washed away?" Xia Yi frowned, "But Yan Fangyu happened to be Having a temper tantrum with Kang Cheng, how could such a coincidence happen in such a big city like Yan'an?"

Shao Lin glanced at Yan Fangyu's clothes and belongings before he was alive, and said that this possibility sounds unimaginable, but it is not impossible.

Yan Fangyu was wearing an ordinary yellow T-shirt, cheap and unbranded jeans, and a pair of white shoes.They are all street stalls without styles, and the sum will not exceed 100.From the pocket of her trousers, there were several one-yuan coins, and a palm-sized Gucci leather wallet, which contained only more than 300 yuan in cash, without a single card.

"The wallet is still there, so seeking money can be ruled out."

"This corpse can tell us too little." Yu Min sighed, "Was it an accident, suicide, or homicide? Where did she fall from? The mouth of a well? Or a certain building? If we can find out exactly who Yan Fangyu is If the manhole cover fell, perhaps more clues could be found.”

The place where the body was found this time was a culvert where several rainwater pipes gathered—rainwater was collected through rainwater canals and rainwater wells, and was discharged into the culvert from drainage pipes in all directions.The rainwater canal was too shallow and narrow for adults to fall in, so Yan Fangyu must have fallen into a rainwater well.

Rainwater and sewage in Yan'an City are controlled separately.Sewage will be treated centrally before being discharged, while rainwater pipes only need to be simply filtered before being discharged directly into the Haikou rocky beach in the southeast.Many years ago, it was said that in a neighboring city, a little girl slipped and fell into a drainage manhole during a typhoon. Her body washed all the way to the rocky beach along the drainage pipe, and was finally found [-] to [-] kilometers away from the point of falling into the water.

Apparently, Yan Fangyu's body also moved along the drainage pipe.If it were not blocked by the grate for isolating sundries at this location, it would probably appear directly on the rocky beach in Haikou.

So here comes the question—there are thousands of rainwater wells upstream, where did Yan Fangyu fall from?

Shao Lin asked: "Where's Kang Cheng, what's the news? How did you deal with the matter of running away from home?"

Yan Jingjing has always been concerned about this matter: "SweetHeart's official statement has not been issued, but a few entertainment news broke out that Kang Cheng's same-sex prostitution was arrested, but it was quickly suppressed by the company's public relations, and the hot search was withdrawn."

"What Kang Cheng told the police was that he spent money to hire a private detective. Several relatives of Yan Fangyu ran from house to house, but they couldn't find anyone. On May 5, he quietly posted the missing person notice, and the price was very high. Very conscientious, find someone to reward 25w. After all, he is a local tyrant, richer than our bounty suspect."

"But it's such a coincidence that Kang Cheng is indeed a major suspect." Jiang Mo tidied up the documents in his hand, "Xia Yi, you can ask the City Planning Institute and bring someone to investigate which manhole cover has fallen off. A group went to check Kangcheng."

At that time, Xia Yi responded immediately.

however……

When someone Xia came back from calling the Urban Design Institute, there was nothing to love written on his face: "Fuck, I'll tell you a ghost story. There are a total of 50 manhole covers in Yan'an City, involving 16 management units. Is it exciting or not?"

Probably Xia Yi's expression was too aggrieved, like a husky stuffed with high math problems, Shao Lin couldn't help but chuckle.

Xia Yi was annoyed: "Why are you laughing! Let me tell you, we are in a group now, and we have the same blessings and share the same difficulties. Don't think that the matter has nothing to do with you. If your brother Yi tonight If you can't complete the task, don't even think about eating, brother smelly."

The pen in Shao Lin's hand was placed on the table with a "snap", and he raised his eyebrows: "What if I can?"

Xia Yi snorted contemptuously: "If you can? If you can, then from now on, you will be my brother!"

The corner of Shao Lin's mouth twitched imperceptibly, and he turned to look at Yan Jingjing's computer.On the screen, it took half a day to load the map alone.

"Come on, let's remove all the sewage pipes first," Shao Lin said in a calm tone, as if he didn't think it was difficult at all, "Let's just look at the rainwater pipes."

Xia Yi hummed unconvinced: "I know that too!"

Shao Lin moved the cursor: "This is the grate that Yan Fangyu got stuck in. Exclude all downstream manhole covers, and then exclude all upstream manhole covers that do not pass through this grate. By the way, is there any display on the filter grate map?"

"I'll check it out, there should be some..."

"The grate has come out. That's ok, then continue to drain the manhole cover that will be stuck by other grates after falling into the water."

Shao Lin flipped through the 3D illustration of the drainage system, and added another one: "The drainage system of Yan'an City was renovated five years ago, and a few more rainwater pipes were added. The new series of codes start with the letter K, and the rainwater wells come with Reinforced filter screens, all those with K can also be excluded, and people can’t get through.”

After such an operation, there are still more than 8000 suspicious manhole covers.

Yan Jingjing turned her head expectantly: "Teacher Shao, what then?"

Shao Lin was silent for a moment, then turned his head and instructed Xia Yi: "Go and call the municipal government and ask about the complaints about unclosed manhole covers in the last 10 days."

"Ha, ha, ha, ha!" Someone Xia laughed viciously, "You don't know it either!" After speaking, he placed a bottle of "six walnuts" heavily in front of Shao Lin.

Shao Lin: "..."

After the pipeline is divided in this way, it has actually successfully avoided the entire western district, and the manhole covers are completely distributed in the north and east of Yan'an City.This is consistent with Shao Lin's previous conjecture that Yan Fangyu will take the initiative to avoid the CBD area where SweetHeart company is located, the community where Zhu Luo lives, the spas and beauty salons she often goes to - these places where people may recognize them.

Yan Fangyu's own ID card was kept at home, and she didn't bring any fake ID with her.But now, what kind of hotel does not need to swipe the ID card?Then, she can only find some homestays and small hotels that don't check the ID card, or can just fool around...

Those urban villages with a mixed population of floating population.

Shao Lin was thinking—could he boldly select these urban villages directly?Yan Fangyu probably only had small-scale activities in these areas and rarely went out.However, even with this calculation, there are still three suspicious communities left on the map, which is still more than 1000 manhole covers.

At this time, Xia Yi came back with a list of complaints: "Now our city appearance is well regulated. There are only 7 complaints that have not been covered. I wrote down the locations and see if there are any repetitions."

When the results were compared, there was no half overlap.

But that doesn't mean anything either.Maybe Yan Fangyu fell into an undiscovered well.It is also possible that the manhole cover was closed later, but the municipal government was not called.It's also possible that Yan Fangyu didn't fall in by himself at all.

Xia Yi scratched her head, feeling that Jiang Mo had just given herself a proposition: "What are you doing now? Teacher Shao, there seems to be 8000 manhole covers missing between you and my brother."

Shao Lin frowned slightly, and his tone was calm and emotionless: "Don't worry."

"Don't pretend, huh? If you can't do it, you can't do it, and I won't laugh at you." Xia Yi said seriously, "It's late, are you tired? Go to rest when you are tired. I don't think I am in a hurry to find a needle in a haystack Come."

Shao Lin dragged his chin with his hand, rubbed his index finger under the tip of his nose, and fell silent for a while.After a long while, Shao Lin said slowly: "Jingjing, just now you said that Kang Cheng's interview with prostitutes was suppressed by the company's public relations hot search?"

"Yes, yes, this is simply disgusting!"

Shao Lin turned on the computer and searched for a few keywords: "Then are there any Weibo users who protested and expressed their dissatisfaction very frequently a few days ago?"

Yan Jingjing opened her eyes wide in surprise: "I haven't paid attention to this. However, I can write a code and search for it."

Yan Jingjing's writing speed was unsurpassed. Soon, she wrote a crawler program in python, which scraped out all the most popular news blog comments related to "Kang Cheng's colleague was arrested for prostitution".

Shao Lin said: "Normal people may read the news, comment once and then stop commenting. Even if they quarrel with netizens, they are still torn on the same news. But Yan Fangyu is different. She is likely to be in every news. Commented. Look for users who are highly active and have commented at least three articles with the same content but different publishers."

As a result, the screen is full of sailors and marketing accounts.

Yan Jingjing smiled: "Teacher Shao doesn't play Weibo much, does he?"

Shao Lin: "..."

"Don't worry, among these users, May 5—er, give Yu Min a fault—after May 29, how many have never posted?"

"18!"

"The one who has been scolding Kang Cheng?"

Yan Jingjing's eyes lit up, and she was suddenly excited: "Just one! ID Little Bee!"

As soon as Shao Lin snapped his fingers, he called Xia Yi again: "Go, check your IP."

IP is fluid. Although it is impossible to freeze specific coordinates, it can vaguely circle an area.In the end, Yan Jingjing covered the scope of this IP area with the manhole cover map, and only an urban village "Luo Village" in the north of the city was completely nested with it.

At two o'clock in the morning, Shao Lin smiled slightly: "How many are left now?"

Yan Jingjing cheered: "97!!!"

Xia Yi was stunned: "Fuck?!"

"Go to Luo Village tomorrow, take a group of people to take pictures and ask, and then see which manhole cover has been opened recently." As he said, Shao Lin raised his head, looked at Xia Yi, and pulled a beautiful line from his collarbone to his neck. line.

Shao Lin was a little sleepy, and his speech was not as thoughtful as usual. He narrowed his eyes slightly, and he looked lazy and elegant: "Officer Xia, call Brother Sheng to listen?"

The author has something to say:

The number of manhole covers was made up by me, the proportions may not be correct.Just in Shanghai, some people say 500w and some say 50w, I don’t know, so I just scribbled, maybe 500w is all, and 50w is the water.It is also possible that 500w is a misrepresentation.This piece of information was found to vomit blood, so Shishi decided to use magic.
