Chapter 268 Do More Cases
"I'll go down and dig, and you can take a look." Wang Chuanxing drove for two hours, borrowed an auxiliary policeman 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 particularly good brain and thinks a lot, but he has never had many opportunities.Because in the provincial capital, there are many young people like him who rely on themselves.

This time, Wang Chuanxing was worried about finding someone else to share the possible credit. He didn't even want to find the seconded person, so he borrowed an auxiliary policeman and came here with a shovel without saying anything.

The auxiliary police officer who was borrowed was in his 30s and didn't care what to do.Wang Chuanxing asked him to be a guard. He found a shaded position, sat down and played with his mobile phone.

Wang Chuanxing dug down the dry well, and the more he dug, the more he felt guilty.

He came a little too fast, without preparing anything, he brought a big shovel and a flashlight, thinking it would be enough.Unexpectedly, the well looks good down the well, but the real downhole is so oppressive, and as he keeps digging down, he is getting farther and farther away from the wellhead, not to mention the poor light, and he still feels a little timid in his heart.

This kind of well is really convenient for burying corpses.

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

Burying bodies underground can also easily mask the smell and prevent wild animals from digging them out, the latter being the main reason why wild burials are found.

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

This is actually a tradition in the funeral industry.The law of the beautiful country stipulates that the corpse must be buried below six feet. In ancient Chinese etiquette, the minimum depth is also six feet, which is suitable for officials of the sixth rank. Higher-level officials can be buried deeper, but they are not buried shallower. that's it.

Another cold knowledge that modern people rarely know, digging a hole is very tiring.A group of young people in five rows, each with a shovel to dig a hole, if the target is 2 meters deep, then five people are exhausted, and the hole dug is only enough to bury one person.

In other words, if the five friends who are hacking together decide to kill one of them because of losing streak or other reasons, it is best to invite him to participate in the digging, especially the last 1.5 centimeters, which are usually very hard and difficult to dig. If you kill people, it is very likely that everyone will be exhausted after digging to a depth of 1.6 meters and [-] meters.In the end, it is likely to fall short because of insufficient depth.

The burial is simple. When the newly dug out soil is backfilled, it doesn’t matter if there are four or five people. Even three or two people can complete the corresponding workload.It is equivalent to saying that as long as five people dig a well, it is no problem to bury three people.

The final core problem is that the extra soil is not easy to deal with.The ancients would take the opportunity to make grave mounds, which also happened to be convenient for marking the location of the ancestors' remains.

Burying the corpse would become a burden. If the local soil was hard, the extra soil would be very large, and it would be difficult to clean it up just by spilling it. This is also the main reason why Qi Yongbin can't bury things in his small courtyard.

Dry wells are simple, people or things are stuffed in, and if you want to cover up, you can pour soil, even if you pour two meters of soil, if it is the soil that has 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 it will not be visible.

Wang Chuanxing didn't know how deep to dig, and he was afraid that the digging would not be fine 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 underground can't be used, it's good to help illuminate it.

Just as he was thinking, the shovel made a bang.

Wang Chuanxing immediately got out of the way, and then looked over in a dim light, and he saw a long-handled dagger.

"Lao Li, Lao Li." Wang Chuanxing shouted a few words, then turned on the flashlight again, took out his mobile phone, and took two photos.

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

After taking it out completely, you can see the blood groove on the dagger. Wang Chuanxing lowered his head and thought, and thought, could this be the reason why the blood splashed on the murderer?

Next to the position of the dagger, the bloody clothes were actually exposed. Wang Chuanxing planed the clothes more carefully. After the whole process was completed, more than an hour passed.

"Pull me up." Wang Chuanxing put the things directly into an evidence box, and climbed up the well by himself.

In the yard, the sun is shining and the breeze is blowing.

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

However, at this moment, Wang Chuanxing couldn't take care of so much. He took out his mobile phone as quickly as possible, just like the superior reported:

"I found the blood coat and the dagger, and took pictures of the whole process... Yes, the blood coat hasn't been cleaned yet, so I should be able to come up with something."

"Yes, it's in the suspect's yard. Yes, Jiang Yuan analyzed it. He believed that the suspect didn't have much time to deal with the murder weapon and bloody clothes, so he judged that the burial should have been carried out near his own home. He highly suspected that it belonged to the victim's family. Yards, especially dry wells, should be a priority."

"This... When Director Wan notified me, I didn't think much about it, because it was Director Wan who called, so I came here directly..."

After Wang Chuanxing made a phone call, thin sweat broke out on his forehead.

He is so nervous.

On the one hand, Wang Chuanxing wanted to get as much credit as possible into his bosom, on the other hand, he did not dare to offend Director Wan and Jiang Yuan, because they must have more information in their hands to prove their inferences, and they might not be able to do so. There are telephone recordings and even document records.

At the same time, Wang Chuanxing did not dare to offend his immediate leadership.I have to explain clearly to others that I am not acting on my own initiative, let alone having a bride and forgetting my old mother.

The auxiliary policeman next to him was much older than Wang Chuanxing, and he could guess a little from his appearance.After Wang Chuanxing's call was over, the auxiliary police officer joked, "You graduates from college, you must have a 20-pound brain in your 2-pound head. It's exhausting."

"Are there only two catties of brains in a twenty catties brain?" Wang Chuanxing was delighted.

"Being a policeman is good for having a thicker head." The auxiliary policeman smiled, neither envious of Wang Chuanxing's bright future nor caring about the evidence he brought.

Auxiliary police are given five social insurances and one housing fund, and wearing uniforms is awe-inspiring to go out, and it is convenient to do small things occasionally. Although you may occasionally meet a little disgusting people, as long as you don’t leave the jurisdiction, you will be more happy than worried.

For what Wang Chuanxing is after, at least for now, he is not pursuing it.

……

Changyang Criminal Police Detachment.

in the large conference room.

Those who are doing PPT and those who have already written on the whiteboard are all in chaos.

The murderer has been caught, and the PPT and whiteboard of the criminal investigation department all focus on fixed evidence, that is, the bloody clothes, the murder weapon and the confession.

In this case, witnesses have become unimportant.

Normally, when the bloody clothes or the murder weapon cannot be found, it is also a normal operation to use PPT to speculate.If you guess correctly, then write a special book, if you fail to guess correctly, you can publish another issue of PPT to judge the reason.

There is only one problem with this method, that is, the murder weapon and the bloody clothes cannot be found immediately!
If the conclusion is immediately available, wouldn't the current reasoning be judged and compared immediately?

As for the several elite police officers in the meeting room, apparently none of them deduced the correct location.Otherwise, just send someone to search for the murderer's house.

Wan Baoming looked on coldly, seeing these familiar and unfamiliar scenes, he couldn't help sighing softly: "It's really embarrassing that the extremely gorgeous decoration and painstaking decoration still look like a fortress on the beach in the end."

"It doesn't cost much to write a ppt." Wei Zhenguo also looked at the chaotic scene and shook his head.

"The PPT is not well written, but it will consume the recognition of the leader." Wan Baoming said: "This is the most advanced cost consumption.

"What the hell is leadership approval?"

"It is the level of the leader who comes, the time and frequency of coming will be different."

Just as he was talking, he saw two white shirts walking in with a few policemen in normal uniform.The one walking at the back was Wang Chuanxing, with his chest raised and his head straight, looking quite heroic.

Regular clothes are police uniforms that look good but are not often worn but are often worn in film and television dramas. For police officers with duties and jobs, wearing regular clothes to work is equivalent to wearing a suit to work, and the level of pretense is greater than actual ability.

Therefore, low-level police officers wear duty uniforms every day, and those who can wash their pants a few times are considered clean and tidy.

However, the leaders who sit in the office are different. They only wear duty uniforms when they appear on the scene, and the clothes they wear every day are ordinary clothes.

Just like now.

"It's Captain Yu." Wan Baoming reminded Jiang Yuan.

Jiang Yuan had a lot of contact with Yu Wenshu when he was working on the Tan Yong case, that is, the case where the woman was imprisoned in the community dug a basement by himself.

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

Jiang Yuan and the others sat up straight.

Yu Wenshu entered the conference room and looked around, but he came straight to Jiang Yuan.

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

"Sit, sit, sit." Yu Wenshu took Jiang Yuan's arm, sat down directly next to him, and then said with a smile: "I didn't expect it. I'll see you in a few days. Forensic doctor Jiang is even more powerful."

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

"It's not luck. When you were working on trace evidence last time, I said, clues, and now they really have become clues. I didn't expect, you are doing even better now." Yu Wenshu praised again and again, waving Said: "Wang Chuanxing is also coming, sit by my side, let's take a picture together."

The photographer trotted over quickly.

On Yu Wenshu's left is Jiang Yuan, and on the right is Wang Chuanxing. He took several pictures in a row before he was satisfied.

Yu Wenshu continued: "Jiang Yuan strategized and won a decisive victory thousands of miles away. Wang Chuanxing is good at execution, meticulous and patient, and it is very rare to get the murder weapon and bloody clothes in the first time. It is really amazing to have such a young man in the police system. People are happy..."

Jiang Yuan smiled.

Wang Chuanxing wanted to be serious, but the smile immediately hung up.

Yu Wenshu said to Jiang Yuan again: "You just passed the fingerprint to solve the case a few days ago, and I felt a little different. I didn't expect that you solved the 513 case in just a few days. Did you You know, this case is within us and has been called out as a random crime. Fortunately, I didn't have time to sign it, otherwise..."

Yu Wenshu looked at the young people in the meeting room who were furiously revising the PPT, and whispered deliberately: "Someone wanted to postpone the meeting, but I denied it. I just wanted to see how quickly they changed."

People around laughed softly.

There are not one or two people who want to see the jokes of the elite group.

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

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

Jiang Yuan just happened to be meeting, so he sat beside him and listened quietly.

Yu Wenshu coughed twice, took the microphone, and said, "Not long ago, the criminal policeman Wang Chuanxing of our Changyang City Criminal Police Detachment, who is also the resident criminal policeman for the 513 case, dug out bloody clothes in the dry well of the suspect's house." And the murder weapon, after a quick DNA test, the bloodstains were left by the victim of this case..."

"Although the case is not yet over, the work of the investigation stage has basically come to an end here."

"About the 513 case, I have some conclusions, and now I will talk to you."

"First of all, there are some problems in the decision-making of the direction of the case. Our eyes have been deviated due to the frequent theft and robbery incidents nearby... I still remember that Lao Li said before that the case should be considered comprehensively. It is suggested that we should make a detailed record for everyone in the area. We have not adopted this suggestion, which is problematic..."

"Secondly, we still have a lot of shortcomings in the use of technical weapons. Look at Jiang Yuan's forensic doctor. I heard people say that this time we mainly used bloodstain analysis and footprint identification to solve the case firmly. This is when I was young, technicians The technology used, as it turned out, is now being taken out by a young man like Jiang Yuan and used..."

"Don't look at the old technology, and the new technology, you are even worse." Yu Wenshu nodded his hands and began to read, and said: "The first time I did a case with Jiang Yuan, I said that the trace amount of our detachment The physical evidence laboratory... They all report more or less detection capabilities, and so many detection methods, but they don't talk about this on-site investigation, and they don't mention the ability to extract trace evidence at the scene. I don't understand... In the end, Jiang Yuan did the on-site investigation and trace evidence..."

Jiang Yuan still listened quietly to Yu Wenshu's speech in front of him. At this point, Jiang Yuan sat up involuntarily, and gradually felt outrageous.

What Yu Wenshu said just now seemed to be a conversation between two people.

"Captain Yu has a photographic memory." A female voice came softly beside my ear.

Jiang Yuan turned his head in surprise, and saw a policewoman in regular uniform sitting on the right side at some point.

The policewoman had a hat on her lap, and her legs were raised together, not as wide as the hat.The upper body is slender and straight, which supports the regular clothes very well.

Seeing such a girl with an oval face in the territory of a group of stinky men is really like seeing a white swan in a pile of ugly ducks.

Jiang Yuan gave a little smile politely.

"Jiang Forensic Doctor, I am Tang Jia from the Third Brigade of Criminal Investigation, a colleague of Wang Chuanxing, you need manpower here in Changyang City, you can find me at any time." After Tang Jia finished speaking, she smiled nicely, and then changed into a serious posture. .

At this time, Yu Wenshu's speech was coming to an end, he directly called Jiang Yuan's name, and said, "Jiang Forensic Doctor, please tell us a few words, you can talk about the 513 case, and you can also talk about the next plan. "

"Oh, okay." Jiang Yuan was not stage-frightened. Under the eyes of the crowd, he stood up and said, "For the 513 case, my main idea of ​​solving the case is to use bloodstain analysis to reconstruct the scene. Although there are relatively few bloodstains, reconstruction At the scene, there is actually no strict requirement on the amount of bloodstains..."

After a few simple sentences, Jiang Yuan said again: "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 try to gain something."

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

The crowd 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 gourd, so the gourd babies and grandpas naturally want to encourage him.

At this time, everyone subconsciously had the concept that as long as Jiang Yuan was given a case that included blood analysis and footprints, he would be able to solve it.

To put it bluntly, the existing intranet does not provide direct search, and it is estimated that manual search is required for these two requirements.

But no matter how troublesome manual screening is, there is no trouble solving the case.

If Jiang Yuan can really solve two similar cases, even if everyone sleeps in the garage, their bodies under the coats will still be warm.
