Yangzhou City is close, and the two of them arrived there in more than an hour. When Xu Zheng got the victim's chin bone, Zhang Yuqi also asked Qiao Changling, the captain of the Yangzhou Criminal Police Detachment, "Qiao Brigade, what do you do?" What are the results of the DNA test on your skull?”
Qiao Changling is older, almost fifty years old. "The DNA results came out, but there was no match in the database, and our forensics preliminary identification is that it is a skull fragment of a girl under 16 years old. Our police basically don't have any children of this age." Collect fingerprints, not to mention DNA data.
Now I hope Xiao Xu can seize the time to complete the skull restoration. "
After Xu Zheng arrived here, he had been looking at the jaw bone. It was said to be a jaw bone, but in fact it was only a small section of the gum, and it had also been soaked by strong acid. He got closer and smelled it. In addition to the smell of meat, there was also acid flow. Smell, "Team Qiao, have you found other skull fragments? To be honest, with the current skull, it's a bit difficult, so it will take a little longer."
Qiao Changling was overjoyed when he heard this. It would be okay if it takes longer. As long as it can be done, the forensic doctors in their city will need three days. He can't say 100% that it can be completed. "Xiao Xu, how long will it take you?"
Xu Zhengmo calculated it and said, "Six hours, this is the time for the skull to be restored. You can do the rest of the 3D modeling yourself. Of course, I can help you draw a simulation portrait. This only takes ten minutes."
Upon hearing this, Qiao Changling said nothing and pointed to the workbench with his right hand, "Then I'll trouble Xiao Xu. If you need anything, just tell our colleagues here."
Xu Zheng nodded and started to work. Zhang Yuqi declined Qiao Changling's arrangement. She said that she could just stay here and wait for Xu Zheng, and she happened to look at the old files of the team.
Xu Zheng looked at a small piece of jaw bone carefully. The broken section was probably cut with a kitchen knife. The aunt who scavenged could actually recognize such a piece of bone. It seemed that she also had a different story.
Xu Zheng put back his random thoughts and started to work. He took out a small bottle of blue potion from his pocket. This was a potion that he prepared with the knowledge given by the system after mastering the master-level skull restoration technology and forensic knowledge.
This bottle of blue medicine can be applied to the skull fragments to show the traces of blood vessels on the skull. This allows the skull reconstructionist to follow the blood vessel traces on the bones to further deduce the flow direction of the scalp muscles, and then use the flow direction to deduce the fractured muscles. .
It's easier said than done. This is the first time Xu Zheng has used the potion that he has been preparing for a long time. Not to mention, when it is poured on the bones, lines will form after a while.
In this way, the working time of the skull reconstructionist will be greatly reduced, because with the texture, there is no need to infer the flow direction of blood vessels and muscles bit by bit.
Zhang Yuqi also saw Xu Zheng's operation and asked curiously: "Xu Zheng, what kind of potion are you using? Are the traces of blue branches and vines the traces of blood vessels on the scalp?"
Xu Zheng nodded and told her what he had researched, "This reagent is still under research, and data is still being collected. I don't know if the accuracy is high."
"What is the cost of this medicine? You can develop more and let our skull reconstructionists from all over the city and province help you collect data. This is no better than trying to figure it out on your own."
"Team Zhang, you don't understand. There are tens of thousands of blood vessel traces on the skull. This does not mean that experienced skull reconstructionists can help me collect data. What I want is a very professional person, because a single blood vessel may affect the skull reconstructionists. judgment, thus affecting the appearance of the skull after restoration.
As for the cost, it’s not high, it’s just the contrast agent used for trace inspection plus some chemical ingredients.
Don't talk about it outside, I'll study it later. "
Because the knowledge of skull restoration was given to him by the system, the potion he developed, the systematic knowledge of forensic medicine, and the fact that he had just studied as a postgraduate student under Professor Ji Qianli. In the eyes of outsiders, he had not yet begun to learn the skills. Finished product?
In fact, this is not to say that there is no such thing. On the contrary, this kind of thing has been around for a long time. It has always been used in hospitals to check bleeding points and apply contrast agent to the patient's blood vessels. By observing the contrast agent, they find the place where the blood vessel ruptures.
After sorting out the knowledge given by the system, Xu Zheng used this contrast agent for reference.
He just had to do more research to show all the traces of blood vessels on the skull. This was not a short-term project. If successful, it would definitely be a great tool for skull reconstructionists, saving countless time.
Of course, if it succeeds, the first step is to apply for a patent, and then consider monetizing it. You have to know how many forensic doctors there are in the country, and how many can restore skulls, especially now that many murderers commit crimes, and many of them physically kill the victims. People are completely wiped out, but because the bones of the victims are difficult to wipe out, there are a large number of skull reconstructionists.
After Xu Zheng explained to Zhang Yuqi, he officially started. He is now very experienced in skull restoration, even if the skull has been soaked with strong acid by the murderer.
But as his recovery became more detailed, his mood became more and more painful, because in the end, it turned out that the skull was really that of a fifteen-year-old girl.
She looked quite cute, but after such a beautiful little girl died, her muscles were melted, her skull was smashed, and the skull fragments were even thrown into the trash can.
I really can't imagine how her parents would feel after knowing this situation?
For Xu Zheng, who had just discussed his children's education with Han Xin a few hours ago, it was the first time that he was opposed to having a daughter. Although his daughter was a little cotton-padded jacket, if he didn't worry about it, it would definitely be a knife in his heart.
Looking at the restorable skull in front of me, the restoration is not complete. There are still some tasks that have not been done, such as the skull and back of the head, as well as the eyes, which are the most time-consuming. If all these tasks are completed, it will take more than two days. Hour.
It's just that what the Yangzhou City police need most now is time, so Xu Zheng decided not to do the rest of the work because he could draw a sketch of the victim once the face was restored.
The sketch was done very quickly. Because he spent three hours reconstructing the skull, Xu Zheng already had a good idea of the girl's appearance. He completed the simulation portrait in less than ten minutes.
The girl in the painting is indeed only about 15 years old. The hairstyle Xu Zheng gave her was designed based on her face shape. If this girl loves beauty and has a good family background, there is a high probability that she will have this hairstyle.
Actually, for girls, they should be in middle and high school at this age, and they only have the same hairstyle.
Six hours have passed since Yangzhou City Police received the report. It took Xu Zheng three hours to reconstruct the skull. It was already past 12 o'clock in the morning. But what is strange is that the girl should be lost. It took at least six hours, and it was so late, but no one reported it.
Since no one reported this, they couldn't identify the victim. So the police have checked everything they can, but still have no clues.
After drawing the simulated portrait, it was discovered that Zhang Yuqi had fallen asleep on the table, and Xu Zheng woke Zhang Yuqi up.
Then, when Zhang Yuqi stood up, he found that the woman had drooled on the table while she was sleeping, and she didn't know it yet.
But just when Xu Zheng wanted to remind her, a group of colleagues from Yangzhou City came outside. Qiao Changling took the lead. After greeting Xu Zheng and the others, he looked at the simulated portrait painted by Xu Zheng, and then arranged for his colleagues to collect photos. The girl’s information is collected through the intranet and household registration files.
Seeing Zhang Yuqi also looking at the photos, Xu Zheng used his hand to scrape her saliva onto his palms, and then wiped it on his pants. Not to mention, this woman drooled a lot. She drooled while sleeping in this place. This heart Really big too.
The colleagues in Yangzhou City were very enthusiastic. Xu Zheng drew a simulated portrait. Because it took time to search for information, they took advantage of this time to treat Xu Zheng and Zhang Yuqi to a late-night snack in the office.
The investigators worked overtime and probably ate about the same thing. They gave Xu Zheng and the others a bucket of instant noodles, a salted duck, and some other snacks.
Xu Zheng did not affect his appetite because he touched the skull. On the contrary, he ate nutritious meals every day these days. The taste of the instant noodles suddenly opened up his taste buds. Regardless of the fact that it was still steaming, he opened the lid and started eating. Not to mention, it smells really good.
It's just that his nose is very sensitive now, and he can always smell the smell left by touching Zhang Yuqi's saliva with his right hand just now.
Not to mention, it smells like peach. Alas, this captain didn't even find a boyfriend, so he wasted such a good skin.
No, or find a girlfriend, because everyone in the second brigade did not feel that their brigade captain was a woman at work.
After a while, Qiao Changling came over with a sad face. Seeing Xu Zheng and Zhang Yuqi still eating, he forced a smile and asked them to continue eating.
Zhang Yuqi put down her fork, "Team Qiao, is there any information about the girl? What's the situation?"
Qiao Changling sighed, "We matched the girl's information in the city's student registration files, and then found her family's information.
What we have found so far is that this girl is from a single-parent family and lived with her father after her parents divorced.
We have contacted her teacher and father. Her father is also working very hard during the day and driving an online car-hailing service at night. When he heard that the criminal police team was coming, he thought we were fraudsters.
Alas, I don’t know how to say yes to him later? "
This kind of thing may be something he can't help with, but after hearing what he said, he lost the appetite to continue eating, "Team Qiao, I still have a few parts to do in the skull recovery. Your forensic doctor can also finish it." , so, let’s say goodbye first.”
Qiao Changling was polite again and personally sent Xu Zheng and the others to the car.
On the way, Zhang Yuqi was driving and saw Xu Zheng still thinking about the little girl just now, "No one wants this kind of thing to happen. You can help your colleagues in Yangzhou City to restore the skull, which is already a great help.
By the way, Team Qiao gave me a red envelope of 1,000 yuan, which is all yours. "
