Chapter 258: Do a Few More Cases

"I'll go down to dig, you help me watch." Wang Chuanxing drove for two hours, borrowed an auxiliary police officer from the local police station, and returned to Qi Yongbin's home to dig the dry well.

He is the kind of person with a very good brain, and he thinks a lot, but he has never had any opportunities. Because in provincial capital cities, there are plenty of young people like him who rely on themselves.

This time, Wang Chuanxing was worried that if he found someone else, the potential credit would be shared, so he didn't even want to find the borrowed person. He just borrowed an auxiliary police officer, didn't say what it was, and brought a shovel over.

The borrowed auxiliary police officer was over 30 years old and didn't care what he was doing. Wang Chuanxing asked him to be a guard, he found a shaded position, sat down, and started playing with his phone.

Wang Chuanxing dug downward in the dry well, feeling more and more guilty as he dug.

He came a bit too fast, didn't prepare anything, just brought a large shovel and a flashlight, thinking it was enough. _o_m He didn't expect that the well looked fine from above, but the real well bottom was so oppressive. Constantly digging downward, the distance from the wellhead became farther and farther, the light became worse, and there was a little bit of fear in his heart.

This kind of well is really convenient for burying corpses.

The well bottom has a self-purification function, and abundant microorganisms will decompose the corpse in a shorter time.

Burying corpses in the well can also easily cover up the smell and prevent wild animals from digging them out, which is the main reason why wild burials are discovered.

In addition, a cold knowledge that modern people know less about is that if a corpse is buried more than two meters deep, it will basically not be dug out by other wild animals, and the smell will not come out either.

This is actually a tradition in the funeral industry. The laws of the United States stipulate that corpses must be buried more than six feet deep. In the etiquette of ancient China, the minimum depth was 6 feet, suitable for sixth-rank officials. Higher-level officials could be buried deeper, but none were buried shallower.

Another cold knowledge that modern people know less about is that digging a hole is very tiring. A group of young people in a five-person team, each with a shovel to dig a hole, if the goal is 2 meters deep, then by the time the five people are exhausted, the hole dug is only enough to bury one person.

In other words, five friends playing together, if they decide to kill one of them because of a losing streak, it is best to ask them to participate in digging the hole first, especially the last thirty centimeters, which are usually very hard and difficult to dig. If they kill the person in advance, it is very likely that they will be physically exhausted when they dig to a depth of 1.5 or 1.6 meters. In the end, it is very likely that they will fail because the depth is not enough.

Burying is simple. The soil just dug out, filling it back, it doesn't matter if there are four or five people, even three or two people can complete the corresponding workload. In other words, as long as five people dig a good hole, burying three people is no problem.

The core problem in the end is that the extra soil is not easy to handle. Ancient people would take the opportunity to make a grave mound, which also happened to be convenient for marking the location of the ancestors' remains.

Burying corpses becomes a burden. If the local soil is hard, the amount of extra soil will be very large. It is very difficult to sprinkle it clean, which is the main reason why Qi Yongbin found it difficult to bury things in his own courtyard.

The dry well is simple. Put the person or things in, and if you want to cover it up, pour soil. Even if you pour two meters of soil, if it is soil that has already been prepared, one person can easily do it.

If you are afraid that the soil quality is too new, add water. Add a few buckets of water, and you won't be able to tell.

Wang Chuanxing didn't know how deep to dig, and was afraid of not digging carefully enough, so he had to adjust the position of the flashlight from time to time.

At this time, he regretted not bringing two more people down together.

Even if the well bottom couldn't be unfolded, it would be good to help shine a light.

Just thinking about it, the shovel made a thud.

Wang Chuanxing immediately moved aside, looked over with the faint light, and sure enough, saw a long-handled dagger.

"Old Li, Old Li." Wang Chuanxing shouted twice, then turned on the flashlight again, took out his phone, and took two photos first.

After Old Li came, Wang Chuanxing asked him to turn on the law enforcement recorder, and he slowly took out the long-handled dagger.

After it was completely taken out, one could see the blood groove on the dagger. Wang Chuanxing lowered his head and thought, could this be the reason why blood splashed onto the perpetrator?

Next to the dagger, the bloody clothes were actually exposed. Wang Chuanxing dug more carefully for these clothes. After the whole process was done, more than an hour had passed.

"Pull me up." Wang Chuanxing put the things directly into an evidence box and climbed up the well on his back.

In the courtyard, the sun was bright and the breeze was blowing.

The itching all over Wang Chuanxing's body seemed to have been blown away. _o_m

However, at this moment, Wang Chuanxing couldn't care about so much. He took out his phone as fast as he could and reported to his superior leader:

"Found the bloody clothes and dagger, filmed the whole process... Yes, the bloody clothes haven't been washed, they should be able to extract something.

"Correct, right in the suspect's courtyard. Yes, Jiang Yuan analyzed it. He believed the suspect didn't have much time to dispose of the murder weapon and bloody clothes, so he judged that they should have been discarded or buried near his home, and highly suspected that the dry well should be prioritized."

"This... when Director Wan notified me, I didn't think much, because it was Director Wan who called, so I just came over..."

After Wang Chuanxing finished the call, fine sweat appeared on his forehead.

He was too nervous.

On one hand, Wang Chuanxing wanted to scoop as much credit into his arms as possible. On the other hand, he didn't dare to offend Director Wan and Jiang Yuan, because they definitely had more information to prove their inference, and maybe even phone recordings and document records.

At the same time, Wang Chuanxing didn't dare to offend his direct leader. He had to explain clearly that he didn't act without authorization, and he didn't forget the old love after having a new one.

The auxiliary police officer next to him was much older than Wang Chuanxing. Seeing his appearance, he guessed a little. After Wang Chuanxing finished the call, the auxiliary police officer teased: "You university graduates, in a 20-jin head, you must grow 2 jin of brain flowers. It's exhausting."

"In a 20-jin head, only grow 2 jin of brain?" Wang Chuanxing laughed.

"Being a police officer, it's good to have a thicker skull." The auxiliary police officer smiled, neither envious of Wang Chuanxing's bright future nor caring about the evidence he brought.

The auxiliary police officer has five insurances and one fund, wears a uniform and is majestic when going out, and it is convenient to handle small things occasionally. Although he occasionally encounters some disgusting people, as long as he doesn't leave the jurisdiction, he is happier than troubled.

For what Wang Chuanxing pursues, at least for now, he doesn't pursue it.

Changyang City Criminal Police Detachment.

In the large conference room.

Those making PPTs and those who had already written on the whiteboards were all in a mess.

The perpetrator had been caught, and the PPT and whiteboards of the criminal investigation department focused on fixed evidence, which was the bloody clothes, murder weapon, and confession.

In this case, witnesses became unimportant.

Normally, in the absence of bloody clothes or murder weapons, it is normal to use PPT to speculate. If you guess right, then write about it extensively. If you don't guess right, you can issue another PPT to judge the reasons.

This method has only one problem, which is that the murder weapon and bloody clothes cannot be found immediately!

If the conclusion is available immediately, then the current reasoning, isn't it going to be judged and compared immediately?

And the elite police officers in the conference room obviously didn't reason out the correct location. Otherwise, they would have sent someone to search the perpetrator's home directly.

Wan Baoming watched coldly from the sidelines, looking at these familiar yet strange scenes, and couldn't help but sigh: "Extremely gorgeous decoration, painstaking embellishment, in the end, it is still like a castle on the beach, which is really sigh-worthy."

"Writing PPT doesn't cost much either." Wei Zhenguo also shook his head looking at the chaotic scene.

"If the PPT is not written well, it will consume the leader's recognition." Wan Baoming said: "This is the highest-level cost consumption."

"What kind of ghost thing is leader recognition?"

"It's the level of the leader who comes, the time they come, and the frequency they come will be different."

Just as he was talking, two people in white shirts, leading several police officers in regular uniforms, walked in. The one walking at the very end was Wang Chuanxing, standing tall, looking straight ahead, quite heroic.

Regular uniform is the police uniform that looks good but is not often worn, and is often worn in movies and TV shows. For police officers who have duty tasks and work, wearing regular uniform to work is equivalent to wearing a suit to work, and the level of showing off is greater than actual ability.

Therefore, grassroots police officers usually wear duty uniforms.

Duty uniforms, those who can wash their pants a few more times, can be considered clean and tidy.

However, leaders who sit in the office are different. They only wear duty uniforms on very few occasions when they appear at the scene. The clothes they wear daily are regular uniforms.

Just like now.

"It's Team Leader Yu." Wan Baoming reminded Jiang Yuan. Uncorrected update

Jiang Yuan did the Tan Yong case, which was the case where a woman was imprisoned in a basement in a residential area, and had more contact with Yu Wenshu.

However, the protagonist of that time, at least the protagonist in the investigation stage, was mainly Liu Jinghui.

Jiang Yuan and the others all sat up straight.

Yu Wenshu entered the conference room, looked around, but went straight to Jiang Yuan.

"Team Leader Yu." Jiang Yuan and the others stood up one after another.

"Sit, sit, sit." Yu Wenshu pulled Jiang Yuan's arm, sat down right next to him, and then smiled: "Didn't expect it, after a few days of parting, seeing you again, Forensic Expert Jiang is even more amazing."

"It's also good luck." Jiang Yuan said modestly.

"This is not luck. When you were doing trace evidence last time, I said that clues are now really becoming clues. Didn't expect it, you are doing even more amazing things now." Yu Wenshu praised repeatedly, and waved his hand: "Wang Chuanxing, come over too, sit on my side, let's take a photo together."

The photographer ran over in small steps.

Yu Wenshu had Jiang Yuan on his left and Wang Chuanxing on his right, and was satisfied only after posing for several photos.

Yu Wenshu then said: "Jiang Yuan is resourceful and wins thousands of miles away. Wang Chuanxing has good execution, is meticulous and patient, and was the first to retrieve the murder weapon and bloody clothes, which is also very rare. It is really gratifying to have such young people in the police system..."

Jiang Yuan smiles.

Wang Chuanxing wanted to be serious, but a smile hung directly on his face.

Yu Wenshu said to Jiang Yuan again: "You passed the fingerprint case a few days ago, and I felt a different taste. Didn't expect it, in just a few days, you solved the 513 case. You don't know, this case was already called a random crime internally. Fortunately, I didn't have time to sign it, otherwise..."

Yu Wenshu looked at the young people in the conference room who were frantically modifying PPTs, and deliberately said in a low voice: "Someone wanted to postpone the meeting, but I denied it. I just wanted to see how fast they could modify it."

People around let out a light laugh.

There was more than one person who wanted to see the elite team make a fool of themselves.

Yu Wenshu smiled and said a few more words before going to his seat.

In the conference room, with the arrival of several leaders, the meeting officially began.

Jiang Yuan was just happening to be there, so he sat on the side and listened quietly.

He saw Yu Wenshu cough twice, took the microphone, and said: "Just a short while ago, Wang Chuanxing, a criminal police officer of our Changyang City Criminal Police Detachment and a resident criminal police officer of the 513 case, dug out bloody clothes and a murder weapon in the dry well of the suspect's home. After rapid DNA testing, it was proven that the bloodstains were indeed left by the victim of this case..."

"Although the case has not ended yet, the work in the investigation stage has basically come to an end here."

"Regarding the 513 case, I have some summaries, and now I will chat with everyone about them."

"First, there were some problems with the case direction decision. Our attention was biased because of the frequent burglary and robbery cases nearby... Remember that Old Li said before that the case should be considered comprehensively? At that time, he proposed whether to conduct a detailed statement for everyone in the area. We didn't adopt this suggestion, which was a problem..."

"Second, there are still major defects in our use of technical weapons. Look at Forensic Expert Jiang. I heard people say that this time it was mainly solved by using bloodstain analysis and footprint identification. This is the technology used by technicians when I was young. As a result, now it is actually taken out and used by young people like Jiang Yuan..."

"Don't look at the old technology not working, you are even worse at new technology." Yu Wenshu was already pointing his hand and reciting: "The first time I did a case with Jiang Yuan, I said, our detachment's trace evidence laboratory... has already reported how much detection capability it has, and how rich the detection means are. But this scene investigation, they don't say it, the extraction capability of trace evidence at the scene, they don't mention it themselves, our criminal police."

Also don't understand... In the end, it was Jiang Yuan who did the scene investigation, did the trace evidence..."

Yu Wenshu spoke in front, and Jiang Yuan was still listening quietly. When he said this, Jiang Yuan couldn't help but sit up and gradually felt it was absurd.

The words Yu Wenshu just said seemed to be the conversation between the two.

"Team Leader Yu has a photographic memory." A female voice came softly in his ear.

Jiang Yuan turned his head in surprise and saw a female police officer sitting on his right at some point.

The female police officer had her hat on her lap, her two legs were put together, and they were not as wide as the hat. Her upper body was slender and upright, making the regular uniform look very good.

In a place full of stinky men, seeing such a goose-egg-faced girl really felt like seeing a white swan in a pile of ugly ducklings.

Jiang Yuan gave a polite little smile.

"Forensic Expert Jiang, I am Tang Jia from the Third Criminal Investigation Detachment, Wang Chuanxing's colleague. If you need manpower in Changyang City, you can find me at any time." After Tang Jia finished speaking, she smiled very beautifully and changed into a serious sitting posture.

At this time, Yu Wenshu's speech also came to an end, directly calling Jiang Yuan's name, saying: "Forensic Expert Jiang, you also say a few words to us. You can talk about the 513 case, or talk about the next plan."

"Oh, okay." Jiang Yuan was not stage-frightened, stood up under everyone's gaze, and said: "For the 513 case, my main investigation train of thought was to use bloodstain analysis to reconstruct the scene. Although there was relatively little blood, reconstructing the scene actually has no hard requirements for the amount of blood..."

After saying a few simple sentences, Jiang Yuan added: "As for the next plan, I still want to select a few cases that can use bloodstain analysis and footprints, do a few more cases, and strive to have some gains."

As soon as this sentence was said, Yu Wenshu took the lead in applauding.

Everyone applauded vigorously.

At this time, if Jiang Yuan talked about trace evidence, everyone might just listen. But he just used bloodstain analysis and footprints to solve such a difficult case, and now he says he wants to follow the example, so the gourd children and grandfathers naturally want to encourage him.

At this time, everyone subconsciously has such a concept: as long as a case containing bloodstain analysis and footprints is given to Jiang Yuan, he can solve it.

Speaking of which, the existing intranet does not provide direct search, so it is estimated that manual retrieval of these two requirements is needed.

But no matter how troublesome manual screening is, it is not as troublesome as solving a case.

If Jiang Yuan can really solve two more similar cases, even if everyone sleeps in the garage, the body under the coat will be warm. ===== CHAPTER 259 =====
