The long night finally passed. Perhaps it was the end of the year and the students were on vacation. The most common things to deal with this night were family conflicts and setting off fireworks.
The former is mostly due to children's education issues. The father thinks it is okay to watch TV and play with mobile phones in moderation, but the mother thinks it is not allowed for even a second. She keeps arguing and makes trouble when her temper gets up. If there is a trouble, the police will be called. That’s all for them.
Regarding the latter, Xu Zheng couldn't remember how many years it had been since fireworks and firecrackers were banned. They banned them every year, but they couldn't stop them every year. However, the higher-ups refused to change the policy. It was not just front-line police officers and comrades in comprehensive law enforcement who were affected.
Anyway, as long as it is not excessive, Xu Zheng will not care. As for the children and young people who run away after setting off the fireworks, Xu Zheng will not chase them.
Some are small Internet celebrities whose live broadcasts have not become popular. In order to gain fame and gain traffic, they play live fireworks. You can catch them. It will give them traffic. You can fine them and close their accounts. Soon they will switch to new accounts for live broadcasts. .
After working until 7 a.m. and handing over his shift, Xu Zheng breathed a sigh of relief. If no major collective incident occurred, the policemen on duty could take a day off.
Xu Zheng didn't have breakfast because he was still planning to go to Forensic Doctor Lu's place to lie down. They had already come to him twice, so he would feel bad if he didn't go there.
Xu Zheng was not polite when meeting with forensic doctor Lu. Xu Zheng directly asked to see the condition of the skull first.
What is now in front of Xu Zheng is a skull that has been restored with soft plastic mud, and next to it is a forensic doctor in his 30s.
When Forensic Doctor Lu brought Xu Zheng over, the forensic doctor quickly stood up and said, "Teacher, is this Master Xu Zheng? He is so young."
As he spoke, he stretched out his hands, but when he saw that they were covered with yellow mud, he smiled sheepishly and gestured to Xu Zheng.
Forensic doctor Lu quickly introduced, "Xiao Xu, this is Jiao Guangnan, a forensic doctor from Danyang City, who is also one of my students. No, the skull reconstruction we all made is unrecognizable. It seems to be Chinese New Year now, and there is no eucalyptus at all." If we push forward, the Danyang City Branch will be 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 working, a lot of bone fragments were found. Although these bone fragments had been integrated with the dry and hard cement, they were broken into pieces of cement. It can still be found that these are human bones.
Now many workers have seen it, so the local criminal police brigade was asked to solve the case as soon as possible.
What they have been able to collect now is a quarter of the skull, mainly the occipital bone and mandible, as well as other bits and pieces of skull fragments.
While Xu Zheng was observing carefully, Jiao Guangnan continued to introduce the situation to him. They had broken cement blocks by hand in this 100-meter section, and so far they had only found so much.
It is estimated that to find them all, we must break up all the cement roads in this 10-mile stretch. "This project is very big. The branch cannot decide whether to do it or not, but what we can do now is to determine the identity of the victim." Come down and find the murderer."
Xu Zheng nodded slightly. So many bones had to be broken and mixed into the cement mixer. Before paving them on the road, they had to check that there were no bones on the ground. This was obviously a gang.
Either the paving workers or the contractors and paving workers. As long as the construction workers of this section of road are found, it is not difficult to break the eucalyptus.
He asked casually, "Have you detected the age of the deceased?"
Forensic doctor Lu explained to Xu Zheng, "Because cement is highly corrosive, it will have a great impact on the identification results. In addition, the murderer also cooked the body of the deceased, leaving only the bones, which were then broken into pieces and finally mixed with cement." .
Therefore, checking bone density to measure age is a problem. "
Xu Zheng was interested in this skull, but not very much. "Have you made a 3D model of the skull? Let me take a look."
Looking at the 3D data graph on the computer screen, Xu Zheng began to simulate in his mind. The corrosiveness of cement is indeed very strong. In addition, the density of these bones is compressed after the cement dries hard, and the vehicles that often pass by on the road make the bones more corrosive. Slightly deformed.
These issues must be taken into consideration, and the 3D data model in front of Xu Zheng was generated based on the current skull data. It did not take into account the deformation of the skull over the years.
But how can they know how much forensic doctor Lu needs to change the data?
Xu Zheng also has no experience or data.
As for the restored skull in front of me, forensic doctor Lu did it based on his feeling and experience. Now that the results of his skull restoration are out, it is obvious that it failed.
"Master Lu, Master Jiao, I don't need to tell you that I have no experience with such a compressed and deformed skull.
What I can do is the same as you, keep trying and making mistakes, what do you think? "
Xu Zheng made it very clear that he could agree to do it, but he could not guarantee the success rate. With this skull now, no one could guarantee it. Unless the forensic doctor Yuan from Nanhai Province who had already retired was 30 years younger, he would probably dare to say 100%. Probably ninety.
"That's okay, Xiao Xu. You can restore the skull and hand it over to the Danyang City Branch. That's it." Forensic Doctor Lu assured Xu Zheng.
"Okay, let's start now. When we're done, I can go home and sleep." Xu Zheng simply agreed and started right away.
But Forensic Doctor Lu advised: "Xiao Xu, why don't you go back and take a nap first, and then do it after you wake up..."
"What's the point of procrastinating? My colleagues in Danyang City are all impatient. The one who dies is the most important. I can hold on for a while longer."
"Forehead..."
After Xu Zheng said that, he started to work. He found a brush and water and first removed the soft plastic mud on the skull. Remove the mud, brush it clean, wipe it with a towel, then gently rub the surface of the head occipital bone with your fingers, design the next idea according to the lines on the skull, and push it back to the entire skull step by step.
It's easy to say that. Xu Zheng deduced while doing it. Sometimes he felt something was wrong and had to start over. It was actually the deformation of the skull that caused the variables in Xu Zheng's deduction to increase exponentially.
Because there is a part of the mandible, it can be directly determined to be female. The mandible is slightly smaller, which means that the skull is not large. However, considering the 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, I touched the soft plastic mud on the skull. Unknowingly, it was around three o'clock in the afternoon. Finally, a restored skull with eyes closed was completed under Xu Zheng's hands.
He looked at it and said, "Master Lu, please get a piece of paper and pen, and I will draw eyes."
"Master Xu, my master and Brother Cui will go back to rest if they can't hold on any longer. Let me help you here." Wang Dong, Lu's apprentice, was standing behind Xu Zheng with a pen and paper, showing great respect and respect for Xu Zheng. I was so impressed that I even changed my title to Master Xu.
Xu Zheng didn't pay attention to this. He took the pen and paper and spent another ten minutes drawing a pair of eyes, "Wang Dong, don't you happen to know how to operate software? That's just right. You can handle the rest of your work. I Let’s go back first.”
After saying that, Xu Zheng stood up, his head a little dizzy. Only then did he feel tired, hungry and sleepy, his whole body ached and his feet were numb.
However, his gains this time were not small. After seven consecutive hours of work, his mind was so deep that his understanding and techniques of skull restoration have reached a master level.
This is also thanks to the advanced forensic identification technology endowed by the system.
Before leaving, Xu Zheng said to Wang Dong who was sending him off: "When the results come out, you can send them directly to the Danyang City Branch and let them search for them directly based on the map."
Wang Dong was a little suspicious. The master said that this compression-deformed skull would require constant trial and error. However, after an hour of completion, he handed it over to the Danyang City Branch. The branch took the photo and visited it within a radius of 30 miles. Before 9 p.m. Point was recognized.
