civil forensic

Chapter 554
"No gurgling...not gurgling..."

The birds outside the window were chirping in an orderly manner, and there seemed to be a sweet smell in the air.The green radish beside the bed is like waking up from a dream, its leaves are green and trembling slightly.

Jiang Yuan woke up naturally after sleeping, rolled up the quilt, and didn't want to get up for a while.

It wasn't until the birdsong disappeared that Jiang Yuan got up lazily and went downstairs to have breakfast.

Breakfast is still fragrant beef soup.

The chef recognizes Jiang Yuan, and his attitude is even more kind, which makes people feel even more regretful.

"This way." Huang Qiangmin arrived earlier, and waved when he saw Jiang Yuan.

"Yellow Bureau." Jiang Yuan sat down with soup.

"I'll go back today." Huang Qiangmin was in a good mood, and said with a smile: "The team has to be taken back, and I always feel uneasy staying here. I'll also go back to deal with the recent work."

Huang Qiangmin specifically explained his itinerary to Jiang Yuan.

Jiang Yuan said, "Bon voyage", and then asked: "Then I will continue to work on the case in Luojin?"

"Okay, it depends on what you like. Anyway, now it's a case-by-case discussion. Just let me know in advance." Huang Qiangmin laughed.

There is a profit-sharing package, so there is no need for it now.

Huang Qiangmin has seen police stations in many places and used Jiang Yuan's leadership, and he will never forget it afterwards.

Quick and accurate case-solving, a large amount of objective evidence, a complete chain of evidence, and a non-sloppy style are all Jiang Yuan's advantages in criminal investigation.

In the current environment, Jiang Yuan is the only one who picks people, so don't worry about not being able to sell them.

"However... the Haidilao chef's case here has not been investigated yet, so open a new case?" Huang Qiangmin is still a little worried.

He was not worried that the case would not be solved, but that Jiang Yuan would be under more and more pressure during the process of solving it.

Yesterday's investigation was full of thunder and rain, and the suspects brought back for interrogation were basically cleared of suspicion, which made the investigation of the case enter a period of self-doubt.

To be reasonable, the investigation on the first day is the most promising result.I didn't even find any clues on the first day, and the following days were even more difficult.

Jiang Yuan drank half a bowl of beef soup. By the way, he recalled the photos of the crime scene and the scene he had seen later—the bloodstains had been cleaned up, and the group rented house was full of people, including the dead. In the single room, a vigorous young man was also re-lived-no matter from which angle you look at it, the probability of an acquaintance committing a crime is extremely high.

"At present, there are no other clues or evidence, and insisting on investigation should be the most reasonable plan." Jiang Yuan shook his head.

There should be no easy cases in the homicide backlog.

This principle is probably understood by everyone in the Luojin City Bureau, but the truth is that the sacrifices in reality must be paid.

Mapped to everyone's work and study, if you keep reading and studying every day, constantly pressurize, and keep investing, then I will tell you that you will eventually gain something, but every time you take an exam, your score will not increase, and your ranking will not be good. When it comes to promotion, how many people can persevere?
The only person the Air Force loves forever is the fisherman.Ordinary people still need feedback.

"If you open a new case, Luojin City will do an investigation, and they don't have any manpower for you." Huang Qiangmin is mainly worried about this.

Jiang Yuan naturally thought about it, and then said: "In the early stage of investigation, there should not be many people employed. If manpower is needed later, I want to transfer people from the backlog special class."

Most of the staff in his backlogged case team are seconded, and they are now scattered in several places to handle the case, that is, to finish the previous case-solving the case is only the prologue of a case, and the latter is just sorting out The dossier is enough to annoy ordinary people to death.Later, from the inspection to the litigation link, people are always necessary to cooperate.

The most important thing is that many of Jiang Yuan's cases are for the death penalty, and in this kind of cases, the suspects basically have to go to the second trial, even if it's just to delay time, they will make this choice.

During the period from the second trial to the approval of the death penalty, there are easy cases and annoying cases.

But in any case, the main job of the criminal police is to solve the case, especially for the police in Jiang Yuan's special case.

Huang Qiangmin didn't care, nodded and said: "You can use it as long as you need it. Let me know if there is any new situation in the case, and Luojin City is also here. Don't agree to their other conditions. There are many cases in the ministries and commissions. There's no need to stay in Luojin for too long. They're almost empty."

The resources of a police station are limited, and no police station can solve murder cases continuously.Moreover, solving a case also requires the support of various departments. In the current environment, the criminal police team alone will definitely not be able to handle it.

Jiang Yuan is engaged in technology, in the final analysis, he eats resources.Especially evidence such as trace physical evidence, put it in the former Ningtai County Bureau, don't even think about it.Even if it is given to provincial capital cities like Changyang City or Luojin City, it is not very easy.

Jiang Yuan is currently working on three major cases for Luojin City, and the Luojin City Bureau is also under pressure.

After drinking two bowls of beef soup, Jiang Yuan went downstairs to send Huang Qiangmin into the car, and watched a group of more than a dozen cars leave one by one.

This time, the leaders of the Luojin City Bureau did not see him off, and Quan Dang didn't know how Huang Qiangmin left.

Huang Qiangmin himself doesn't care about these things. He will definitely return to escort the supplies back this time, which is only equivalent to leaving temporarily.

Jiang Yuan called Pang Jidong, and then took his car to the funeral home.

913 drowning case.

This is a murder case Jiang Yuan chose for Pang Jidong.

Drowning is arguably the most widespread and common application of forensic botany.

Because drowning is always accompanied by the accumulation of water in the lungs of the deceased.And stagnant water, not only plankton, but always algae.

Sometimes, even a simple contact with a body of water can contaminate the algal components in it.Even crime scenes with stagnant water, such as ponds and swimming pools, have all kinds of algae.

All of these can be used as evidence.

Using algae evidence to solve crimes has been used in modern forensic science for many years. It belongs to the early application of forensic botany. Jiang Yuan feels that it is very suitable for Pang Jidong's introductory education.

When several people arrived at the funeral home, the first thing they did was to check the lung samples left before.

The original forensic doctor has done a good job, not only did the stomach contents and lungs, but also took samples from the bone marrow.

This is more professional behavior.Because if the deceased died of drowning, he would usually inhale or swallow some water violently, and natural water must contain diatoms.Diatoms are smaller than ordinary algae and will enter various organs in the human body, including bone marrow, along with the blood.

Furthermore, if the victim is dead and the heart has stopped, the diatoms are not transported to various organs in the body.As a result, no diatoms, or only very small amounts of diatoms, can be found in the internal organs.The latter is due to the presence of diatomaceous earth, which causes some toothpaste, or metal polishing and other environments to have diatom contact.

All in all, when a large amount of diatoms is found in the internal organs, the deceased is considered to have died of drowning.Due to the high degree of sealing of the bone marrow, the proof of the bone marrow is the strongest, and the problem of diatomaceous earth is eliminated.

It is equivalent to saying that there are diatoms in the bone marrow, and the person died by drowning, which is the gold standard of drowning in forensic medicine.

Not only that, but the diatom population in the bone marrow is also consistent with the diatom population in the drowning water.Slightly less, but the main types are basically the same.

Yes, like the pollen map, algae don't work alone.It is difficult for a single algae to prove anything, and the algae community or the diatom community has a higher level of probative power.

"Not bad." Jiang Yuan looked at the evidence of algae preserved in the container and was very satisfied.

The bottle's label records the case number, the name of the deceased, the date and location of the sampling, and numbered evidence, among other information.

"Ordinary forensic doctors wouldn't make such trouble." Jiang Yuan pointed to the extraction bottle of algae in the bone marrow.

"I'm also very interested in forensic botany." Lu Jie, a forensic doctor in Luojin City, hurriedly said.

It was because he knew a little that he was more attentive to Jiang Yuan.

"The diatoms in the bone marrow are not easy to extract?" Jiang Yuan asked with a smile.

"Well, it was dissolved with strong acid, which is quite dangerous." Lu Jie also nodded with a smile.

Seeing everyone laughing happily, Pang Jidong couldn't help laughing too, and said, "Looking at it this way, this case will be easier to handle?"

"Of course not." Jiang Yuan still smiled and said: "The previous evidence is very complete, which shows that it is difficult to solve the case through the original evidence. And the evidence is very good, which shows that finding new evidence is not easy. easy."
