National Forensic Doctor

noon.

It was the time when the sun was at its strongest. Wang Zhong suddenly took out a 10-centimeter-long red mahogany sword from his neck. Holding the hilt in his hand, he stood in a lunge with his legs and started stabbing with a "haha" sound in his mouth.

Jiang Yuan, who was sitting in front of the computer, stopped touching his skull and looked at Wang Zhong in confusion.

"Team Wu taught me that after touching the corpse, it's best to drive it away when you return to the office. It also scares the demons and ghosts around you and lets them know that we are not easy to mess with. At the time when the yang energy is strongest every day, use The peach wood sword has the best effect in sword dancing. I checked the azimuth and altitude angles of the sun." Wang Zhong said in a serious tone, while the peach wood sword in his hand had not stopped yet.

Jiang Yuan believed that Wang Zhong's tricks were really taught by his master Wu Jun. Ordinary people can't play with such style.

Jiang Yuan only said: "Then let's keep our voices down so as not to disturb people in other offices. We are still in Longli County."

"The voice is the Qi of the Dantian, so I can just keep quiet, but the effect may be a little worse." Wang Zhong still looked very obedient, closed his mouth, and continued to work hard with his whole body.

Jiang Yuan took a second look and thought it was pretty good. People who do trace examinations often sit in front of the computer, and exercise all day long while sitting. It is still good for the body, but I am a little confused.

Jiang Yuan then asked: "Why did you learn this from him?"

"I didn't become a disciple, I just learned a little bit from him, which is equivalent to being a registered disciple." Wang Zhong glanced at Jiang Yuan cautiously and said, "Captain Wu only taught me some popular techniques."

"Okay." Jiang Yuan felt that Wang Zhong probably didn't understand what mass technology meant, but he was busy enough doing cranial reconstruction surgery. If Wang Zhong wanted to do it, he could do it.

Wang Zhong continued to jump.

I danced about ninety-nine and eighty-one times, almost 18 times in one group, five groups in total. I stopped when I felt sweat on my forehead.

Sitting back on the chair, Wang Zhong panted and put the peach wood sword back on his neck, and whispered: "Brother Jiang, actually what Captain Wu taught makes sense. I have been practicing for a while, and I feel that my body is Everything is fine."

Jiang Yuan thought to himself, if you don't exercise on a daily basis, your body will definitely feel comfortable if you suddenly increase the amount of exercise.

Wang Zhong looked at Jiang Yuan's expression and recalled what Wu Jun said

He shook his head silently, lit a stick of incense on the table, and explained: "Captain Wu gave it to me."

Seeing that Jiang Yuan had no objection, Wang Zhong got up again to boil water, make tea, and open the window for ventilation.

After finishing the lap, I saw a few new cars with Changyang license plates coming downstairs.

"Brother Jiang, someone from the provincial department should be here." Wang Zhong stood at the window and looked for a while, then said, "I think it's Forensic Doctor Zhai who came here? He brought many people with him."

We knew in advance that the provincial department was going to send someone, so it was not surprising that Dr. Zhai would come.

Today, forensic doctor Zhai is still a flower in the Shannan Provincial Department, planted wherever needed. When looking for Liu Jinghui, he was dispatched. The case of corpses abandoned on National Highway 805 in Luyang City was also initially conducted by forensic doctor Zhai.

Of course, it can also be said that the identification that Jiang Yuan overturned before was made by forensic doctor Zhai.

Jiang Yuan stood up and took a look, and saw forensic doctor Zhai who looked like a little old man, followed by seven or eight strong men - forensic doctors moved corpses every day, even if they were not strong. Unless you are like forensic doctor Zhai, after you have become famous, someone will help you lift the legs and move the body. The worst thing is like Mei Fang, who doesn't even have an assistant. Occasionally, you can catch a criminal policeman and become a strong man, like Amitabha. Policewomen or veteran policemen who are not easy to manage will sweat more after dissecting a body than eating a meal of spicy hotpot.

The forensic doctor with a men's gang behind him walked with different momentum. When he came to the office, forensic doctor Zhai said angrily: "Forensic doctor Jiang, we are here to see you."

"Welcome, welcome." Jiang Yuan was waiting at the door, still holding the skull in his arms.

"Is this the skull you want to restore?" Forensic Doctor Zhai glanced across Jiang Yuan's face, landed on the skull, and said casually: "A middle-aged woman weighing over 100 pounds?"

It is slightly more difficult to determine gender and age through the skull than through the pelvis, but it is not too difficult. However,

Forensic doctor Zhai can see it at a glance, which proves his vision and confidence.

In contrast, judging whether you are fat or thin is simpler. Because fat particles will leave marks on the outermost bone of the skull, the fatter the person, the rougher the outer layer of the skull, while the skull of a purely thin person will appear extra smooth.

The outer layer of the skull held in Jiang Yuan's arms looked smooth. Needless to say, the body fat rate was not too high. plus female

The body fat rate itself is much higher than that of men, so her weight is just over a hundred pounds at most.

Jiang Yuan was not surprised that Forensic Doctor Zhai could see that the latter was more of a casual conversation, so Jiang Yuan nodded and said: "That's more or less the case, a woman around 34 years old who has given birth and is lighter in weight. He must have worked hard all year round.”

"I'm impressed." Forensic Doctor Zhai nodded. He had seen this body before.

The forensic doctors who came with him followed him into the office.

This office was an office of the Longli County Criminal Division Squadron, which was temporarily vacated for Jiang Yuan. The corpse and autopsy room are both in the funeral parlor. Not only are they far away, but the temperature is also very low, making them unsuitable for long-term work.

Forensic Doctor Zhai brought a total of 8 forensic doctors, all of whom were grassroots forensic doctors being trained by the provincial departments, mainly young forensic doctors from the district public security bureaus of some cities.

In terms of level, the district public security bureau and the county public security bureau have similar levels. They are also on the grassroots front line and are the first person responsible for facing corpses. However, precisely because of the large amount of business and busy work, grassroots forensic doctors have very little time to improve themselves. Especially when working independently, promotion is even more difficult.

In some cities, the solution to this situation is to send forensic scientists from the municipal bureau to help, supervise, or teach. This is the system in Qinghe City, for example. As a result, forensic doctor Wang Lan embarked on business trips every day.

But some cities will have different solutions, especially if the municipal bureau’s forensic doctors are not strong enough, or if the municipal bureau’s forensic doctors are promoted to leadership positions, they will not be able to circulate. Then the technical skills of the county bureau or district bureau’s forensic doctors , over time, it may become deformed.

The provincial department holds some training courses and various training conferences every year, which can be regarded as a channel for improving skills for those who are interested. However, improving skills usually does not bring material benefits.

Several young forensic doctors entered, curiously observed Jiang Yuan's office, and naturally began to glance at Jiang Yuan's computer screen.

The 3DSler Jiang Yuan is using is quite complex. If it were not for the skills provided by the system, it would be normal for it to take several months to learn just this system.

The domestic police star CCK also has actual combat cases, and it is also a software that everyone can see every day. In comparison, not being complex enough also means not being detailed enough.

"You've really started skull reconstruction." Forensic Doctor Zhai clicked his tongue twice, then asked: "Does it have to be skull reconstruction?"

"Not necessarily, I haven't tried any other methods." Jiang Yuan told the truth, he just wanted to use this trick.

Forensic Doctor Zhai smiled, looked at the skull again, and said, "If we can do it, it will be easier to determine the source of the corpse than to investigate."

If the skull is not used for restoration, the most common method is to first find the source of the corpse based on the attachments on the corpse, that is, clothing, accessories, etc. If this is not possible, autopsy or forensic anthropology techniques must be used to find the source of the corpse. Regardless of the source of corpses, they must cooperate with large-scale investigations.

After the skull restoration is completed, it is reasonable to investigate. However, it is easier to conduct an interrogative investigation like looking at a person's face than to find a 35-year-old dancer with a sprained ankle.

The most important thing is that the face detection is highly accurate and is not easy to miss.

In the investigation, the most feared thing is omissions. This is also the reason why Jiang Yuan insisted on Xu Taining taking action during the 805 case.

It is equivalent to saying that troubleshooting is either expensive or risky. Either way, it is slow.

Moreover, the expensive version is not without risks.

However, in general, the advantages of using skull restoration to find the source of corpses are obvious, the effect is good, and the overall cost is low. The only drawback is that

few people.

Naturally, forensic doctor Zhai doesn't know how to do it.

To put it bluntly, the little old man with a skinny face and dull expression in front of him should be the leader in Shannan Province in terms of the number of corpses dissected. Especially in the early years, when there were few forensic doctors in various places, Lao Zhai often went to one county to dissect corpses.

However, forensic doctor Zhai did not have time to participate in skull restoration, which requires complex talents.

"What step have you taken now?" Forensic Doctor Zhai was slightly concerned. He was still willing to understand the technology of the new era.

Jiang Yuan then sat in front of the computer and said: "We are currently doing edge detection. Because the Laplacian operator is sensitive to high-frequency models, we consider low-pass filtering the image before filtering with the Laplacian operator. What I choose now is Gaussian low-pass filtering, using Gaussian operator and Laplacian operator to form a single loG operator."

After hearing this, Forensic Doctor Zhai stood up and said, "Show me that file, and take pictures of all the bones."
