Yangzhou City is close, and the two of them rushed there in more than an hour, and when Xu Zheng got the victim's jaw bone, Zhang Yuqi also asked Qiao Changling, the captain of the heavy eucalyptus brigade of the Yangzhou City Criminal Police Detachment, "Team Qiao, what are the results of the skull DNA test you did?" ”

Qiao Changling is older, almost fifty years old, "The DNA results are out, but there is no match in the database, and our forensic doctor has preliminarily identified this as a fragment of the skull of a girl under 16, a child of this age, our police basically did not collect fingerprints, not to mention DNA data."

Now I hope that Xiao Xu can hurry up and complete the skull restoration. ”

After Xu Zheng came here, he has been looking at this chin bone, saying that it is a chin bone, but in fact, it is only a small part of the gums, and it has been soaked in strong acid, he got close and smelled it, in addition to the smell of meat, there is also the smell of sour, "Team Qiao, have you found other skull fragments?" To be honest, with the current skull, it is a bit difficult, so it will take a little longer. ”

Qiao Changling was overjoyed when he heard this, it was no problem to take a long time, as long as it could be done, it would take three days for the forensic doctors in their city, so he didn't dare to say 100% that it could be completed, "Xiao Xu, how long will it take you to do this?" ”

Xu Zhengmo calculated, "Six hours, this is the time for the recovery of the skull, and you can do the rest of the 3D modeling yourself, of course, I can help you draw a simulated portrait, this ten minutes is enough." ”

When Qiao Changling heard this, he didn't say a word, and pointed to the workbench with his right hand, "Then it's a little troublesome, if you need to tell our colleagues here." ”

Xu Zheng nodded and started working, Zhang Yuqi declined Qiao Changling's arrangement, she said to stay here and wait for Xu Zheng, and she just happened to look at the old files in the group.

A small section of the jaw bone, Xu Zheng looked at it carefully, the section of the fracture was probably cut out with a kitchen knife, such a piece of bone, the scavenging aunt could actually recognize it, it seems that she is also a person with a different story.

Xu Zheng retracted his thoughts and began to work, he took out a small bottle of blue potion from his pocket, which was the potion he had concocted with the knowledge given by the system after mastering the master-level skull restoration technology and forensic knowledge.

This bottle of blue potion is applied to the skull fragments, which can show the traces of blood vessels on the skull, so that the skull restorer can further deduce the flow direction of the scalp muscles along the blood vessel marks on the bones, and then infer the broken muscles through the flow direction...

Easier said than done, Xu Zheng has been preparing a potion for a long time This is the first time to use it, not to mention, it is poured on the bone, and the lines will be formed after a while.

In this way, the work time of the skull restorer is greatly reduced, because with the lines, there is no need to deduce the flow of blood vessels and muscles.

Zhang Yuqi also saw Xu Zheng's operation, and asked curiously: "Xu Zheng, what kind of potion are you, and the traces of the blue branches and vines are the traces of blood vessels on the scalp?" ”

Xu Zheng nodded and told her what he had researched, "This reagent is still being studied, and it is still collecting data, so I don't know if the accuracy is high." ”

"How much does this potion cost? You develop a little more, and let our city-wide and provincial skull restorers help you collect data, which is no better than your own exploration. ”

"Team Zhang, you don't understand, there are tens of thousands of blood vessel marks on the skull, this is not to say that an experienced skull restorer can help me collect data, I want a very professional person, because a blood vessel may affect the judgment of the skull restorer, thus affecting the appearance of the skull after restoration.

As for the cost, it is not high, it is the contrast agent used for trace detection plus some chemical ingredients.

Don't talk about it yet, I'll study it. ”

Because the knowledge of skull restoration was systematically given to him, and the systematic knowledge of forensic medicine was studied, and there was an on-the-job graduate student who had just studied Professor Ji Qianli, in the eyes of outsiders, the skills had not yet been learned, and this was all a finished product?

In fact, this kind of thing does not mean that there is no such thing, on the contrary, this kind of thing has been there for a long time, and it has always been the hospital to check the bleeding point to create a contrast agent on the patient's blood vessels, and find the place where the blood vessels are ruptured by observing the contrast agent.

Xu Zheng has learned through the system, and after sorting it out, he has borrowed this contrast agent.

It's just that he has to study all the vascular traces on the skull, this is not a short-term project, if it succeeds, this is definitely a great weapon for the skull restorer, saving countless hours.

Of course, if it is successful, the first step is of course to apply for a patent, and then consider realization, you know, how many forensic doctors in the country, how many will restore the skull, especially the current murderer, many of them are physically eliminated from the victim's body, but because the victim's bones are difficult to eliminate, therefore, there will be a large number of skull restorers.

After Xu Zheng explained to Zhang Yuqi, he officially started, and he is indeed very experienced in skull restoration now, even if this skull has been soaked by the murderer with strong acid.

It's just that the more detailed he recovered, the more sad his mood became, because in the end, the skull was really a little girl about fifteen years old.

It looks quite cute, but after such a beautiful little girl died, her muscles were melted, her skull was shattered, and even the skull fragments were thrown into the trash.

I can't imagine how her parents would feel when they found out about this situation.

For Xu Zheng, who had just discussed his children's education with Han Xin a few hours ago, for the first time, he had the idea of resisting having a daughter, although her daughter was a small padded jacket, but if she didn't worry, it would definitely be a knife to the heart.

Looking at the recoverable skull in front of me, it is not considered to be completed, and there are still some work that has not been done, such as the skull and the back of the head, and the eyes that waste the most time, if all these tasks are done, it will take nearly two hours.

It's just that what the police in Yangzhou City need most now is time, so Xu Zheng decided not to do the rest of the work for now, because after restoring the face, he can draw a sketch of the victim.

The sketch was very fast, because after three hours of skull restoration, Xu Zheng had already succeeded in the girl's appearance, and he completed the simulated portrait in less than ten minutes.

The girl in the painting is indeed only about 15 years old, and the hairstyle that Xu Zheng gave her is designed according to her face shape, if this girl loves beauty and has a good family situation, it is very likely that it will be this hairstyle.

In fact, girls, at this age, should be in junior high and high school, and there are only a few hairstyles.

Six hours have passed since the Yangzhou police received the report, and it took Xu Zheng three hours to restore the skull, and it was already more than 12 o'clock in the morning.

If no one reports this, it is impossible to find out who the victim is, so the police have now checked everything they can, but there are still no clues.

After drawing the simulated portrait, he found that Zhang Yuqi had fallen asleep on the table, and Xu Zheng woke up Zhang Yuqi.

Then, when Zhang Yuqi stood up, he found that the woman was drooling on the table when she was asleep, and she didn't know it herself.

But just when Xu Zheng wanted to remind her, a group of peers from Yangzhou City came outside, Qiao Changling took the lead, and after greeting Xu Zheng and them, he looked at the simulated portrait drawn by Xu Zheng, and then arranged for his colleagues to collect photos and collect information about the girl on the intranet and household registration files.

Xu Zheng saw that Zhang Yuqi also went to see the photo, so he took the opportunity to scrape her saliva into the palm of his hand with his hand, and then wiped it on his pants, this woman, not to mention, there is a lot of saliva flowing, and she drools when she sleeps in this place, this heart is really big.

The colleagues in Yangzhou City were very enthusiastic, Xu Zheng drew a simulated portrait, because it took time to find information, so they took advantage of this time to invite Xu Zheng and Zhang Yuqi to have supper in the office.

The investigators worked overtime to estimate that they ate about the same food, and made a bucket of instant noodles for Xu Zheng and the others, and then 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 in the past few days, and the taste of instant noodles suddenly opened his taste buds, and he didn't care that it was still steaming, he opened the lid and ate it, not to mention, it was really fragrant.

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's the fragrance of peaches, alas, this captain doesn't look for a boyfriend, and he is blind to such a good skin.

No, or find a girlfriend, because everyone in the second team doesn't feel that their captain is a woman at work.

After a while, Qiao Changling came over with a sad face, and when he saw that Xu Zheng and Zhang Yuqi were still eating, he smiled reluctantly 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 school registration file, and then checked the information of her family.

At present, it has been found that the girl is a single-parent family, and her parents have followed her father after their divorce.

We have contacted her teacher and father, her father is also very hard, he works normally during the day, and drives an online car-hailing car at night.

Alas, I don't know how to tell him a little later? ”

This kind of thing may be helpless, but after hearing his words, he also has no appetite to continue eating, "Team Qiao, I still haven't done a few parts of the skull restoration, and the forensic doctor on your side can also finish it, so let's leave first." ”

Qiao Changling was polite again, and personally sent Xu Zheng and them to the car.

On the way, Zhang Yuqi drove and saw Xu Zheng still pondering the little girl just now, "No one wants this kind of thing to happen, you can help your counterparts in Yangzhou City restore the skull, it is already a great help."

By the way, Brigade Qiao gave 1,000 red envelopes, all of which are yours. ”
