civil forensic

Chapter 430
noon.

It was the time when the sun was strongest, Wang Zhong suddenly untied a 10cm long red mahogany sword from his neck, held the hilt in his hand, lunged with his legs, and stabbed with a "haha" in his mouth.

Sitting in front of the computer, Jiang Yuan stopped touching the skull and looked at Wang Zhong suspiciously.

"Teacher Wu said that after touching the corpse, it is best to drive it away when you go back to the office or something. It is also to frighten the monsters and snakes around you, and let them know that we are not easy to mess with. During the time when the yang energy is the most prosperous every day, use The mahogany sword has the best effect, I checked the azimuth and altitude angle of the sun." Wang Zhong said it seriously, the mahogany sword in his hand has not stopped yet.

Jiang Yuan believed that what Wang Zhong did was really taught by his master Wu Jun.Ordinary people can't play with such... style.

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

"Voice is the energy of the dantian, so I don't need to make a sound, the effect may be worse." Wang Zhong still looked very obedient, closed his mouth, and continued to work hard with his whole body.

Jiang Yuan took a look and thought it was pretty good.Those who do trace inspection often sit in front of the computer for a whole day, and exercise is good for the body. I am a little confused...

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

"I didn't learn from a teacher, I just learned a little bit, which is equivalent to a registered disciple." Wang Zhong glanced at Jiang Yuan cautiously, and said: "Team Wu only teaches me a little mass technology."

"Okay." Jiang Yuan felt that Wang Zhong probably didn't understand what mass technology is, but he was busy enough doing skull restoration, and Wang Zhong could just jump if he wanted to.

Wang Zhong continued to jump down.

I jumped about ninety-nine and 81 times, almost 18 times as a group, a total of five groups, and I stopped when I saw sweat on my forehead.

Sitting back on the chair, Wang Zhong put the mahogany sword back on his neck out of breath, and said in a low voice: "Brother Jiang, in fact, what Dui Wu taught makes sense. I followed it for a while and felt that my body It's all good."

Jiang Yuan thought in his heart, you who don't exercise every day, suddenly increase the amount of exercise so much, your body must feel comfortable.

Wang Zhong looked at Jiang Yuan's expression, recalled what Wu Jun said, shook his head silently, lit a stick of incense on the table, and explained: "Team Wu gave it."

Seeing that Jiang Yuan didn't object, 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, it should be people from the Provincial Department." Wang Zhong stood at the window and looked at it for a while, then said: "It feels like Zhai Forensic Doctor came here? He brought a lot of people."

Knowing in advance that the provincial department will send someone to come, it is not surprising that forensic doctor Zhai came here.

Today, Zhai Forensic Medicine is still a flower of the Shannan Provincial Department, where it needs to be planted.When looking for Liu Jinghui, he was dispatched. The case of abandoned corpses on National Highway 805 in Luyang City was initially identified by Zhai Forensic Doctor.

Of course, it can also be said that the identification that Jiang Yuan overturned before was done by Forensic Doctor Zhai.

Jiang Yuan got up and took a look, and saw forensic doctor Zhai, who looked like a little old man, followed by seven or eight strong men.Unless it's like Zhai Fayi, someone will help you lift your legs and move the corpse after you become famous. The worst is like Mei Fang, who doesn't even have an assistant. Occasionally catch a criminal policeman and become a strong man, Amitabha. Female policemen or old policemen who are not easy to manage will sweat more after an autopsy than eating a meal of Mala Tang.

The forensic doctor with the men's gang behind him walked with a different aura. When he came to the office, forensic doctor Zhai said in a full-fledged manner: "Forensic doctor Jiang, we're here to see you."

"Welcome." Jiang Yuan waited at the door, still holding the skull in his arms.

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

It is a little more difficult to judge gender and age through the skull than through the pelvis, but it is not too difficult. However, like Zhai Forensic Doctor, he can tell at a glance, which still proves his eyesight and self-confidence.

In contrast, it is easier to judge fat and thin.Because fat particles will leave traces 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 is extraordinarily smooth.

The skull that Jiang Yuan held in his arms looked bare on the outside, so it goes without saying that the body fat percentage would not be too high.In addition, the body fat rate of women is much higher than that of men, so her weight is at most a hundred catties.

Jiang Yuan was not surprised that Zhai Forensic Doctor could tell that the latter was more of a greeting, so Jiang Yuan nodded and said, "It's almost like this. Women around 34 years old have given birth and are relatively light. It should have been worked all year round..."

"I have an impression." Zhai Forensic Doctor nodded.He had seen this corpse before.

The accompanying forensic doctors followed into the office one after another.

This office is an office of the Criminal Division Squadron of Longli County, which was temporarily vacated for Jiang Yuan's use.Both the corpse and the autopsy room are in the funeral parlor. Not to mention the distance, the temperature is still very low, so it is not suitable for long-term office work.

Forensic doctor Zhai brought a total of 8 forensic doctors here, all of them are grass-roots forensic doctors who are being trained by the provincial department, mainly young forensic doctors from district public security bureaus in some cities.

In terms of levels, the District Public Security Bureau and the County Public Security Bureau are at the same level, and both belong to the grassroots front line, and are the first person responsible for facing the corpse.However, it is precisely because of the many businesses and busy work that grass-roots forensic doctors have little time to improve themselves.Especially in the case of independent work, it is more difficult to improve.

In some cities, the solution to this situation is to send a forensic doctor from the city bureau to help, supervise or teach, such as the system in Qinghe City.As a result, Wang Lan's forensic doctor embarked on a daily business trip.

But some cities have different solutions, especially when the forensic doctors of the city bureau are not strong enough, or if the forensic doctors of the city bureau are promoted to leadership positions, they will not be able to circulate. , Over the years, it may be deformed.

The provincial government organizes some training courses and various training meetings every year. For those who are interested, it can be regarded as a channel to improve their skills. However, the improvement of skills usually does not bring material benefits.

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

The 3DSlicer that Jiang Yuan is using is quite complicated. If it is not for the skills given by the system, it is normal to spend a few months to learn 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 contrast, not being complicated enough also means that it is not detailed enough.

"You really did the skull restoration." Forensic Zhai clicked his tongue twice, and asked again: "Do you have to use the skull restoration?"

"Not necessarily, I haven't tried other methods." Jiang Yuan said honestly, he just wanted to use this trick.

Forensic doctor Zhai smiled, looked at the skull again, and said, "If it can be done, it will be easier than investigation to determine the source of the corpse."

If there is no need for skull 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 it is not possible, it is necessary to use autopsy or forensic anthropology techniques to find Regardless of the source of the corpse, it is necessary to cooperate with a large-scale investigation.

Skull restoration is completed, logically it needs to be screened, but it is easier to look at people's faces and find out more than to find a 35-year-old dancer with a sprained ankle.

The most important thing is that the accuracy of face detection is high, and it is not easy to miss.

In the investigation, the most feared thing is omissions, which is also the reason why Jiang Yuan insisted on Xu Taining's involvement in the 805 case.

It is equivalent to saying that the investigation is either expensive or risky, no matter which one is, it is slow.

Also, the expensive version is not without risk.

However, generally speaking, using the method of skull restoration to find the source of corpses has obvious advantages, the effect is good, and the overall cost is low. The only drawback is that few people know how to do it.

Naturally, Zhai Forensic Medicine couldn't do it either.

Speaking of which, the little old man with a thin face and a dull expression in front of him should be the leader in Shannan Province in terms of the number of dissected corpses.Especially in the early years, when there were few forensic doctors in various places, Lao Zhai often went to autopsies from county to county.

However, Zhai Forensic Medicine did not have time to participate in skull restoration, which requires compound talents.

"Which step has been achieved now?" Forensic Zhai was a little concerned, and he would not return. He was still willing to understand the technology of the new era.

Jiang Yuan then sat in front of the computer and said: "Currently we are doing edge detection, because the Laplacian operator is sensitive to high-frequency models, so we consider low-pass filtering the image before the Laplacian operator filtering, Now I choose Gaussian low-pass filter, using Gaussian operator and Laplacian operator to form a single loG operator..."

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