I don't want to solve the case when I'm a little policeman.

Chapter 179 The First Master Technology

The long night finally passed, perhaps because the end of the year was approaching and the students were on vacation. The most dealt with this night were family conflicts and setting off fireworks.

The former, mostly because of children’s education problems, the father thinks it’s okay to watch TV and play with mobile phones moderately, but the mother thinks it’s okay for a second, so they keep arguing, and when they get angry, they make trouble, and when they make trouble, they call the police, cooperating with the police resources That's all for them.

For the latter, Xu Zheng couldn't remember how many years the ban on setting off fireworks and firecrackers was banned every year, and every year it couldn't be banned, but the higher-ups just didn't change the policy, and it wasn't them, front-line policemen and comrades in comprehensive law enforcement who were affected.

Anyway, as long as it wasn't too much, Xu Zheng wouldn't care. As for those children and young people who ran away after the fireworks were set off, Xu Zheng wouldn't chase after them.

Some are small Internet celebrities who did not become popular in live broadcasting. In order to become famous for some traffic, they broadcast live fireworks live. You catch it, just send him traffic, fine him and shut down his account, and he changed to a new account for live broadcast after a while. .

Busy until seven o'clock in the morning, Xu Zheng breathed a sigh of relief when he handed over his shift. If there were no major collective incidents, the policemen on duty could take a day off.

Xu Zheng didn't eat breakfast, because he was still planning to go to Lu Fayi's place to lie down for a while, and he had been looking for him twice, so he felt sorry if he didn't go.

Meeting with Forensic Doctor Lu was not polite, Xu Zheng directly asked to see the condition of the skull first.

Now in front of Xu Zheng is a skull that has been restored with soft plastic clay, and there is a forensic doctor in his 30s next to him.

When Forensic Doctor Lu brought Xu Zheng over, the forensic doctor quickly stood up, "Teacher, is this Master Xu Zhengxu? You are so young."

As he spoke, he stretched out his hands, but seeing that his hands were covered with yellow mud, he quickly smiled embarrassedly, and gestured to Xu Zheng.

Forensic doctor Lu quickly introduced, "Xiao Xu, this is Jiao Guangnan, a forensic doctor in Danyang City, who is also one of my students. No, we can't recognize the skull restorations made by all of us. It seems that it's the Chinese New Year, and the case has not advanced at all. , the Danyang City Branch Bureau is under a lot of pressure."

Danyang City is a county-level city. A section of cement road was renovated locally. However, when the crusher was operating, many bone fragments were found. Although these bone fragments had been integrated with the hard cement, they were broken into pieces of cement. It can still be found that it is a human bone.

Now many workers have seen it, so the higher-ups asked the local criminal police brigade to solve the case as soon as possible.

The quarter of the skull they can collect now is mainly the occiput and mandible, and other bits and pieces of the skull.

While Xu Zheng was observing carefully, Jiao Guangnan continued to introduce the situation to him. They broke all the cement blocks by hand in this 100-meter section of the road, and so far only found so many.

It is estimated that in order to find them all, the concrete road 10 miles away must be smashed. "This project is huge, and the sub-bureau cannot decide whether to do it or not, but what we can do now is to identify the victim." Come down and find the murderer."

Xu Zheng nodded slightly. So many bones had to be crushed and mixed into the cement mixer. Before they were paved on the road, they had to be checked to see that there were no bones on the ground. This was obviously a gang.

It wasn't the paving workers, it was the contractor and the paving workers. As long as the builders of this section of the road were found, the case would not be difficult to solve.

He asked casually, "Have you detected the age of the deceased?"

Forensic doctor Lu explained to Xu Zheng, "Because the cement is highly corrosive, it has a great impact on the identification results. In addition, the murderer also boiled the dead body, leaving only the bones, which were then broken and finally mixed with cement. .

Therefore, checking bone density to measure age is a problem. "

Xu Zheng is interested in this case, but not very much, "Have you done a 3D modeling of the skull? Let me take a look."

Looking at the 3D data map on the computer screen, Xu Zheng began to simulate in his mind that the corrosiveness of cement is indeed great, and after the cement dries hard, the density of these bones is compressed, and the frequent passing vehicles on the road make the bones Slightly deformed.

All these issues had to be considered, and the 3D data model in front of Xu Zheng was generated based on the current skull data, and did not take into account the fact that the skull had been deformed over the years.

But to change the data, how would they know how much Lu forensic doctor changed?
Xu Zheng also has no experience and data.

As for the restored skull in front of him, Doctor Lu did it based on his feeling and experience. Now the result of his skull restoration has come out. Obviously, it failed.

"Master Lu, Master Jiao, I don't need to tell you that I have no experience with such compressed and deformed skulls.

What I can do is the same as you, keep trial and error, what do you think? "

Xu Zheng made it very clear that he can agree to do it, but there is no guarantee of success rate. With this skull now, no one can guarantee it, unless Yuan Fayi, who has already retired in Nanhai Province, is 30 years younger, and it is estimated that he dares to say 90.00% Bar.

"That's okay, Xiao Xu, you can restore the skull and hand it over to the Danyang City Branch, that's all if it works or not." Lu Forensic Doctor assured Xu Zheng.

"That's fine, let's start now. I'll go home and sleep when I'm done." Xu Zheng simply agreed and started.

Lu Fayi persuaded: "Xiao Xu, why don't you go back to sleep first, and then do it after waking up."

"What's the delay? The colleagues in Danyang City are waiting anxiously. The dead are the most important. I can hold on for a while."

"Forehead"

After Xu Zheng finished speaking, he started to work. He found a brush and water to remove the soft plastic clay on the skull.Remove the mud, brush it clean, wipe it with a towel, and then gently rub the surface of the occipital bone with your fingers, design the next idea according to the lines on the skull, and push it backwards to the entire skull step by step.

It's easy to say, Xu Zheng deduced while doing it, and sometimes he felt something was wrong and had to start all over again. In fact, the deformation of the skull caused the variables of Xu Zheng's deduction to double.

Because there is a part of the mandible, it can be directly judged as female, and the mandible is slightly smaller, which means that the skull is not big, but considering the reason of cement compression molding, Xu Zheng judged that the skull should be slightly larger than the 3D data simulated by the computer.

In this way, while deducing, he touched the soft plastic clay on the skull. Before he knew it, it was past three o'clock in the afternoon. Finally, a restored skull with eyes closed was completed under Xu Zheng's hands.

He looked at it carefully, "Master Lu, please bring a piece of paper and pen, and I will draw an eye."

"Master Xu, my master and senior brother Cui couldn't hold on anymore, so we went back to rest first, and let me help you here." Lu Fayi's apprentice Wang Dong was standing behind Xu Zheng holding a pen and paper, showing great respect and respect for Xu Zhengxian. Admired, even the title has become Master Xu.

Xu Zheng didn't pay attention to this, took the pen and paper, swiped, swished, and spent another 10 minutes drawing a pair of eyes, "Wang Dong, don't you happen to know how to operate software? That's right, you can take care of the rest of your work. I Go back first."

After speaking, Xu Zheng stood up, his head was a little dizzy, and only then did he feel tired, hungry and sleepy, his whole body was aching, and his feet were numb.

However, this time he gained a lot. After 7 hours of homework, his mind sank, and his understanding and technique of skull restoration have reached the level of a master.

This is also thanks to the advanced forensic identification technology endowed by the system.

Before leaving the house, Xu Zheng said to Wang Dong who sent him off: "You can send the results directly to the Danyang City Sub-bureau and let them look for them directly with the map."

Wang Dong was a little skeptical. The master said that he would have to keep trying to make this plastic deformed skull, but after he finished it in an hour, he handed it over to the Danyang City Branch. The branch took photos and visited within a radius of 30 miles. The point was recognized.
