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

Chapter 306
At six o'clock in the afternoon, Xu Zheng left work early. He has two classes tonight in the forensic medicine major, and he has to go there. As for the current case of the special case team, it doesn't matter if he leaves. Action, if anything, Zhuang Qiang and Fan Qingqing are dating.

However, because of the two days of committing crimes, they have now moved to a residential house. Obviously, they are planning to commit crimes for a long time.

Probably because they were afraid that the police would catch them?

The only thing is that this group of people currently defrauded not much money, and they were all Zhuang Qiang who came forward. If the police caught them, even if Zhuang Qiang was an undercover policeman to testify, he would not be sentenced for many years.

Even, if they make up the fraudulent amount, the crime will be less.

If they were caught, it meant that they were noticed as soon as they came to Changming this time, which would be a good thing for their superiors.

Perhaps, this group of people came to Changming not only to commit fraud.

What Xu Zheng applied for was not Changming University, but another 211 university in Changming City, Dongda University. This school's medical school has a forensic science major.

Not far away, it is in the Dongda Dingjiaqiao Campus in Gulou District.

06:30 class on time, until [-] o'clock in the evening, to be honest, these theoretical classes are of little significance to Xu Zheng, but since he is here as a graduate student, he can't miss one class, besides, these teachers occasionally tell some classic cases , this is still quite attractive to him.

After all, his working experience is too short, and forensic medicine often relies on experience, but this major is really difficult to learn, and there are very few people who are willing to learn. There are only a dozen people in the whole class.Xu Zheng started class not long after he got there. The theoretical class was no fun at all, and he fell asleep listening to it. It wasn't until the second class, when the teacher talked about the identification of human bones, that he cheered up.

Speaking of human bones, Xu Zheng has done some research on his own. The contrast medium he researched based on the knowledge provided by the system is currently being used in small batches in the forensic departments of Changming Municipal Bureau and various sub-bureaus.

Of course, it is still free for them to use. It is said to be a trial, but it is actually providing data to Xu Zheng, which is mutually beneficial.

When this contrast agent is indeed approved by these forensic doctors, you can apply for a practical patent, and see if you can sell it at a high price. As for setting up a factory to produce it yourself, it will definitely not work, because this contrast agent is also used by forensic doctors to restore the skull. It can be used at any time.

As for why civil servants are not allowed to do business, well, Xu Zheng didn't want to make it too complicated, and he himself was not short of money.

In fact, the contrast agent technology he developed is not too complicated, and the cost is not high. The most important material is the blood contrast agent used in the operating room of the hospital. On this basis, Xu Zheng used his systematic knowledge to add a few things and modify the process. Let the modified contrast agent be used on the bone.

In this way, as long as the bone is not too damaged, as long as the contrast agent modified by Xu Zheng is used, faint blood vessels will appear on it.

This makes it easier for the skull restorer to work without having to use experience and eyesight to explore the direction of the blood vessels on the skull.

However, the greatest use of this contrast agent is to combine it with computer technology. The current computerized 3D skull restoration technology can only collect the complete head of the deceased, and the missing parts are generally restored manually by the restoration technician.

If this contrast agent is used, after angiography on a small piece of skull is done, the computer can simulate the direction of the blood vessels on the back of the skull, and finally automatically generate the appearance of the deceased before death.

This leaves most of the time for the skull restorer.

It's just that Xu Zheng can make a bone contrast agent, but he can't write a 3D program that simulates angiogenesis.

Therefore, after the product passes these forensic tests, Xu Zheng will most likely talk to the General Logistics Department of Public Security Equipment, and he will have to follow the path of his teacher, Professor Ji Dongli.

According to Professor Ji, it would cost hundreds of thousands or millions of dollars to sell technology and patents to them. After all, there are quite a few skull restoration companies across the country.

If it is a foreign market, there will be more, so whether to buy out the patent or share it, we can discuss it at that time.

The reason is, firstly, people commit crimes nowadays mainly by destroying corpses and removing traces, wishing to leave no residue after killing; secondly, when handling a case, first find out the victim's appearance, only with the appearance can the real identity of the deceased be found .

As for the first DNA check on TV, to be honest, in 2034, there is no perfect DNA database for the people of the whole country.

Therefore, according to this trend, there is still a market for Xu Zheng's skull contrast agent.

Unfortunately, the teacher in this class did not talk about the restoration of the skull, but the various scars left after the damage to the human skeleton, such as knife wounds and gunshot wounds, are all basic knowledge of forensic medicine, and only show you the pictures , It's useless, it's all old talk.

After class, Xu Zheng tidied up his textbooks and didn't talk much with the students who came to class together. These working graduate students are usually people after work. It doesn't mean that they plan to have a dinner after class. How can Xu Zheng have this time? , he still has a lot of work to do.

He didn't lie. After class, he ran non-stop to the Provincial Anti-Trafficking Office. It was a follow-up to the case handled last week, the case of child abduction and trafficking that the fourth brother Sun Yanshi participated in five years ago.

Now the Provincial Anti-Trafficking Office has found the location of 12 children based on Sun Yanshi's confession and the memories of those abducting and trafficking accomplices, and has confirmed the DNA data comparison.

It's just that the 12 children have not been officially taken back.

The leader meant to find all the children in this case. According to Sun Yanshi's account of the 26 children, 8 were found after five years of hard work by the police.

At present, there are still 6 children from the Anti-Trafficking Office who have not been found.

It seems that this speed is already very fast.

Over the years, the Anti-Trafficking Office has found 8 children, and in just a few days, they have recovered 12, which is a great contribution.

In fact, Xu Zheng was not too impressed with the decisions of these leaders. There was no need to pick up the children on the same day. In this way, besides showing off the police's contribution, letting the media praise the Anti-Trafficking Office, the police, and cheering up the masses, other useful things What does it do?

Moreover, the parents who lost their children are much more anxious.

Thinking about it this way, Xu Zheng didn't dare to say it out loud. Maybe after a few years, when he became a leader, he would do the same thing, right?

For example, last year the Liulihe Police Station detected a case of theft of an electric car, and Wang Nianpan asked to send the stolen electric car to the victim together.

The stolen electric car was tied with big red flowers. The victim kept thanking the police while receiving the keys. There was a reporter videotaping the whole process, and everyone around took out their mobile phones to take vibrato, and cheers continued.

That scene is still fresh in Xu Zheng's memory.

Obviously, the leaders of the Anti-Trafficking Office want to do the same this time.

It's just that the family members of the abducted children suffered. No, just as Xu Zheng entered the Anti-Trafficking Office, he saw many people gathered in the lobby on the first floor, and there were even a few quilts in the corner of the lobby.

Xu Zheng had never seen such a situation.

I just heard that Han Rui often said that her readers would send her a knife to urge her to change, but in reality, she could still see it, lying on the bed with a quilt to urge others to handle the case.

After a little thought, Xu Zheng knew that these quilts should belong to the families of the six children.

Not knowing the answer but having hope in front of your eyes is the most tormenting thing. Maybe they are sleeping here not only to urge the investigators to find their children, but also to keep hope.

Of course, there were also some people who had very poor eyesight. When Xu Zheng walked in, he saw them sitting on the quilt, clasped their hands together, and kept praying to gods and Buddhas for blessings.

This.
Isn't it the investigators who are doing their best at this time?
Xu Zheng curled his lips, forget it, the world is too ignorant to know them.

At this time, Ye Tao hurried over from the outside, saw that Xu Zheng had already arrived, and hurriedly stepped forward to hold him back, "Why are you here so late, hurry up, we have a few problems here that may need your help."

Director Ye Tao and Xu Zheng have known each other for a long time, and know his ability. No, the clues to the six children have been broken. If the anti-trafficking office investigates slowly, maybe it will take a little longer, and they may be able to find them. So Ye Tao called Xu Zheng over to help.

The leader said that they would be given three more days. If they were not found, they would take the 12 children they found and hand them over to their parents.

As for the remaining six children, we will take a long-term plan.

Sometimes, handling a case requires a lot of effort. This time, the right time, place and people are available. If you can't find it, there is little hope of finding it later.

Of course, this is possible, and no one can guarantee it.

"Brother Ye, you should have told me a long time ago that we should be polite. I have to help with this kind of thing even if I don't sleep!" Xu Zheng said very sincerely, and this was indeed what he was thinking.

Putting aside conscience, just talking about credit, if the Anti-Trafficking Office finds all 26 children, it will be a great credit to Xu Zheng, after all, he was the one who caught and interrogated the fourth brother Sun Yan.

Besides, Xu Zheng had to work hard for this second-class work.

Soon, at the office on the third floor, Ye Tao had his own office as the director. He was at the sub-department level, but the office area obviously exceeded the standard.

This is also the characteristic of the provincial department, and the real job is the main thing.

"Come here, Xiaozheng, I won't talk nonsense with you. Time is tight and the task is heavy. You have to help us break through this problem tonight. Don't worry, it is your credit. When the case is over, I will send a letter to your detachment to praise you." This is the only good thing about Ye Tao, he knows how to write a letter of praise.

In some departments, Xu Zheng rushed over to do skull restoration, simulated portraits, and even check and monitor for them. Oh, now he has one more foreign business, helping people with lip language translation.

After the work is done, some leaders will pay for hard work, and some leaders will give verbal praise. In short, the letter of commendation is still of great use. There are too many of these things.

The two of them didn't have any ink marks. After sitting down, they started working immediately.

It turned out that their problem was that these six children were all sold by a man named Xiang Jinan, but this Xiang Jinan had been missing for five years.

That is to say, this Xiang Jin'an disappeared five years ago when the gang of human traffickers was arrested.

Now that this middleman is missing, it is difficult to find these children in a short time. Ye Tao told Xu Zheng the arrangement of their anti-trafficking office while letting Xu Zheng read the file.

"At present, we are mobilizing the areas where Jin'an may have been active five years ago. The photos of the six children five years ago have been posted in various villages. The local police and governments at all levels are also helping to find them. Unfortunately, It's been a week and still no leads."
