National Forensic Doctor

"No cuckoo...no gurgling..."

The birds outside the window chirped very orderly, and there seemed to be a sweet smell in the air. The pothos next to the bed is like waking up from a dream, its leaves are green and seem to be trembling slightly.

Jiang Yuan slept until he woke up naturally. He rolled up his quilt and didn't want to get up for a while.

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

Breakfast is still fragrant beef soup.

The chef recognized Jiang Yuan and his attitude was even more kind, which made people feel even more sorry.

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

"Huang Bureau." Jiang Yuan sat down with the soup.

"I'm going back today." Huang Qiangmin was in a good mood and said with a smile: "The team has to be taken back. I always feel uneasy staying here. I will 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 in Luo Jin?"

"Okay, it depends on what you like. Anyway, it's a one-on-one discussion now. Just tell me in advance." Huang Qiangmin smiled.

There is a discount on the package, so there is no need for it now.

Huang Qiangmin had seen police stations in many places, and after having used Jiang Yuan's leadership, he would never forget him.

Quick and accurate crackdowns, a large amount of objective evidence, a complete evidence chain, and a style that is not sloppy at all are Jiang Yuan's advantages in criminal investigation.

[A novel app that has been running stably for many years, comparable to the old book-chasing tool, and a source-changing app used by old bookworms,]

In the current environment, only Jiang Yuan can choose people, so there is no need to worry about not being able to sell at a high price.

"But... the Haidilao chef's guinea pigs here haven't found out the results yet, so are they going to open a new guinea pig?" Huang Qiangmin was still a little worried.

He was not worried that the case would not be solved, but that Jiang Yuan would be under increasing pressure during the detection process.

Yesterday's investigation was thunderous and rainy, and the suspects brought for interrogation were basically cleared of suspicion, which brought the investigation into the case into a period of self-doubt.

Logically speaking, the first day of investigation is the most promising. I didn't even find any clues on the first day, and it would be even harder in the following days.

Jiang Yuan drank half a bowl of beef soup and recalled the photos of the eucalyptus discovery scene and the scene he had seen later - the blood stains had been cleaned, and the group rental house was filled with people again, including those who died. In the single room, a vigorous young man also lived again - no matter from which angle you looked at it, the probability of an acquaintance committing suicide was very high.

"There are currently no other clues or evidence, so insisting on investigation should be the most reasonable plan." Jiang Yuan shook his head.

If your life is long-term, you should not have a relaxing life.

This principle is probably understood by everyone in the Luojin Municipal Bureau. However, the principle is such that in reality, efforts must be made.

Mapping it to everyone's work and study, if you keep reading and studying every day, keep applying pressure, and keep investing, then I will tell you that you will eventually gain something, but every time you take an exam, your scores will not increase, and your ranking will not be good. When it comes to promotion, how many people can persevere?

The only one the Air Force will always love is Mr. Fishing. Ordinary people still need feedback.

"If you open a new business, Luojin City will do an investigation, and they don't have the manpower to give it to you." This is what Huang Qiangmin is mainly worried about.

Jiang Yuan naturally thought about it and said: "Based on the preliminary investigation, there should not be many people employed. If manpower is needed later, I would like to transfer people from the dedicated team."

Most of the manpower in his special project team are seconded, and they are currently scattered in several places to carry out the project, which is to put the finishing touches on the previous project - the project is just the prelude to a project, Just the files compiled later would be enough to bore an ordinary person to death. From the inspection to the litigation process, people are always needed to cooperate.

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

During the period from the second trial to the approval of the death penalty, there were relaxing moments and annoying moments.

But no matter what, the main job of the criminal police is always to solve crimes, especially for the policemen in Jiangyuan's special team.

Huang Qiangmin didn't care, he nodded and said: "You can use it. If you have any new situations, just tell me. It's the same here in Luojin City. Don't agree to their other conditions. There are many eucalyptus in the ministries and commissions." Very, there is no need to stay in Luo Jin for too long. They are almost empty."

The resources of a police station are limited, and no station can constantly solve lives. Moreover, breaking the case also requires the support of various departments. In the current environment, the criminal police team will definitely not be able to do it alone.

Jiang Yuan is engaged in technology, but in the final analysis, he only eats resources. Especially evidence such as trace physical evidence would have been unthinkable in the previous Ningtai County Bureau. Even if it is given to provincial capital cities like Changyang City or Luojin City, it is not very easy.

Jiang Yuan has now done three big things in Luojin City, and the Luojin City Bureau is also under pressure.

After drinking two bowls of beef soup, Jiang Yuan went downstairs to see Huang Qiangmin get into the car, and watched as a group of more than a dozen cars filed away.

This time, none of the leaders of the Luojin Municipal Bureau saw him off, and Quan Dang didn't know Huang Qiangmin was leaving.

Huang Qiangmin himself doesn't care about this. He will definitely come back when he escorts the supplies back, which is just like leaving temporarily.

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

913 drowned in eucalyptus.

This is a fate chosen by Jiang Yuan for Pang Jidong.

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

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

Sometimes, even simple contact with water can lead to contamination with algae content. Even crime scenes with standing water, such as ponds and swimming pools, have a variety of algae.

All of these can be used as evidence.

The detection of eucalyptus through algae evidence has been used in modern criminal investigation for many years. It is an early application of forensic botany. It feels to Jiang Yuan that it is very suitable for introductory education for Pang Jidong.

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

The original forensic doctor did a very good job, not only taking samples of stomach contents and lungs, but also bone marrow.

This is a relatively professional behavior. Because if the deceased dies due to drowning, he usually inhales or swallows some water violently, and natural water bodies must contain diatoms. Diatoms are smaller than ordinary algae and can enter various organs in the human body, including bone marrow, along with the blood.

Additionally, if the victim is dead and the heart has stopped beating, the diatoms will not be transported to various organs in the body. As a result, diatoms will not be found in internal organs, or only very small amounts will be found. The latter is due to the presence of diatomaceous earth, which causes some toothpastes, or metal polishing and other environments to come into contact with diatomaceous earth.

All in all, when a large amount of diatoms is found in the internal organs, the deceased is considered to have drowned. Due to the high sealing property of bone marrow, the proof power of bone marrow is the strongest and eliminates the problem of diatomaceous earth.

It is equivalent to saying that if there are diatoms in the bone marrow, the person died of drowning. This is the gold standard for drowning in forensic medicine.

Not only that, but the diatom communities in bone marrow were consistent with those found in drowning waters. Slightly less, but the main types are basically the same.

Yes, like pollen maps, algae don’t do it alone. It is difficult for a single algae to prove anything, but a community of algae or a community of diatoms has a higher level of proof.

"Not bad, not bad." Jiang Yuan looked at the evidence of algae stored in the container and was extremely satisfied.

The label on the bottle records the case number, the name of the deceased, the date and place of sampling, and the numbered evidence and other information.

"Ordinary forensic doctors would not go to such trouble." Jiang Yuan pointed to the extraction bottle of algae in the bone marrow.

"I'm also quite interested in forensic botany." Lu Jie, a forensic doctor from Luojin City, said quickly.

Just because he knew a little more, he was more attentive to Jiang Yuan.

"Isn't it difficult to remove the diatoms from the bone marrow?" Jiang Yuan asked with a smile.

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

Seeing everyone laughing happily, Pang Jidong couldn't help but laugh too, and said, "Look at it this way, will this piece of cake be easier to make?"

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