National Forensic Doctor

Guqi Municipal Bureau.

The setting sun in the evening reflected the red clouds and illuminated the thick clouds clearly.

Following Gao Changjiang's order, the originally quiet courtyard of the Municipal Bureau suddenly became boiling.

Hundreds of police officers appeared from nowhere. They stood up from upstairs, downstairs, basement, and from corners and cracks, and lined up in the yard with complete equipment.

Gao Changjiang put on his training uniform, put on his body armor, put a gun holster on his waist, and looked down as if his whole body was covered in black fire.

"Four children under the age of 5 have been listed by ministries and commissions, and leaders at all levels have shown ardent concern and urging. How important the case is, I don't need to remind you any more. Now I assign tasks, and the units and individuals who receive the tasks must not take credit for it. , don’t back down, don’t be afraid of difficulties or sacrifices, you must do your best to complete the mission, even if a knife comes from the sky and you carry the corpse of your comrade, you have to complete it for me!”

Gao Changjiang held a loudspeaker in his hand, his voice was loud and clear, and his orders were full of force.

Jiang Yuan looked at both sides in surprise, and then asked Dong Bing next to him: "Is this how your senior management usually behaves?"

"Definitely not for small cases. For big cases, that's what the high-level bureau does." Dong Bing replied in a low voice.

Jiang Yuan said "oh". The current police force is not afraid of sacrificing such a slogan, but it is shouting less and less.

Director Gao Changjiang, when doing case analysis, acted like an ordinary police leader, even a little weak. Unexpectedly, when he was ready to go into battle, he would be in high spirits and his courage would double.

Wu Xia used the equivalent of 35 years of experience in staying at a relative's house to understand Jiang Yuan's thoughts. He chuckled and said: "The Gao Bureau used to work in border defense, and later transferred to the local area."

"No wonder." Jiang Yuan nodded in relief, and then looked at the criminal policemen from the city bureau. Teams of them took orders and set off as if heading to the battlefield.

The latest news keeps pouring in like running water.

"The suspect's mobile phone has been identified and the number has been sent over now."

“The WeChat accounts of several people have been confirmed.”

"Their next stop is likely to be all the way out of the provincial border, and then at the Xinming Township Expressway intersection in Xingfeng Province. They have their den in Xinming Township."

"The total number of people in this gang may be more than 30 people. The specific number and the leader of the gang are still uncertain..."

A criminal gang is like an isolated island. Before you have no coordinates and no idea of ​​the location, finding the island is a long and luck-requiring exploration. But after you find the island or even board the island, information suddenly becomes cheap and abundant. stand up.

The next question became how to successfully seize the island and harvest as many fruits of victory as possible. Or bury these dirty fruits.

Jiang Yuan and several experts listened to the reported information and turned to the leisurely stage of checking information.

It wasn't until the number of the 30-man gang was reported that it attracted a little attention.

"This is considered a medium-sized gang. It is likely to be spread across the country. The previous work of investigating old cases can be continued." Zhang Xian arranged with experience.

Jiang Yuan nodded, and without saying anything else, Mu Zhiyang and others started moving on their own.

The criminal policemen of Guqi City next to them were also busy with the search.

Jiang Yuan himself looked at the case and couldn't calm down for a long time.

Trafficking in women and children was at its peak in the 1990s, and ministries and commissions organized four consecutive nationwide anti-trafficking campaigns with remarkable results. By 2000, the number of cases of trafficking in women and children had plummeted, reaching about 2,000 cases per year. But since 2007, such cases have continued to occur at a high rate.

Moreover, the scale of various abduction gangs now tends to increase, and the chains they form are getting longer and longer. Multiple resales have become a common phenomenon. Criminal members have also begun to use single-line connections, and the degree of specialization has been significantly enhanced.

In Jiang Yuan's view, desire for profit and low punishment are complementary to each other.

Members of trafficking gangs generally have low education and low income, and are mainly women.

. It is basically impossible for these people to re-employ after being criminally punished. Nowadays, people who work as cleaners or nannies in the city need to have a clean criminal record. It is obviously difficult for these people to have excellent technical skills, so that the employer pinches their noses and accepts them.

The rest is nothing more than farming or being self-employed. The latter is equivalent to starting a business, but it's not that easy.

In the end, these members of the trafficking gang who have received re-education in prison will find that trafficking in women and children can make money quickly and comfortably, especially children, which require almost no capital, just a few bus tickets and a few days of accommodation. For just one fee, you can complete a transaction and earn tens of thousands of dollars.

Not only that, these ex-criminals who have accepted the iron fist of the dictatorship, once they decide to continue their criminal careers, they become the backbone of criminal gangs. With just a few such gang members, they can support a group of more than a dozen people or even A large group of dozens of people.

The anti-trafficking craze in 2000 ended, and the trafficking gangs revived in 2007. It is difficult to say how many key members of the gang were involved.

"I suggest that we determine the appearance of these gang members in advance. Can we find their photos?" Jiang Yuan looked at Director Wang who was doing image tracking.

"As long as you have the video, it's easy to find someone." Director Wang smiled. His specialty is to track the movements of suspects or anyone through images, which is equivalent to an electronic dog.

This work seems to be a matter of course in film and television works. Once it is shown on the big screen, the camera will follow wherever the suspect goes. In fact, this is naturally impossible. There are always blind spots in cameras, as well as broken cameras and places where cameras are not installed.

The most important thing is that the networking of cameras is a big project in itself. Cameras under different ownership are rarely merged into one system. This is either a permissions issue or a technical issue.

All in all, even tracking a vehicle requires the intervention of a dedicated person to follow it, and it is even more difficult to detail it to people.

"I'll help you later." Jiang Yuan said to Director Wang, and then looked at the social media messages gathered by others.

Director Wang said "yes" and didn't take it seriously.

Jiang Yuan may indeed be very good at trace inspection, surprisingly good, but what role can trace inspection play in imaging? If he really wants a staring "observer", he would rather have Dong Bing like this.

Jiang Yuan released Director Wang for the time being and searched the suspects' chats.

After determining the mobile phone number or account number, the relevant content can be directly retrieved from the backup server. For the police, quickly searching for useful content is the main job. A common example is to determine the group of criminals. If there is a group chat about buying takeout, you can determine the suspect’s residence through the takeout address, or

A lot of information is extracted. If it is useful, it will be sent to the front line. If further investigation is necessary, other front-line personnel can be dispatched.

The advantage of cases listed by ministries and commissions is that there will be no shortage of resources and manpower. In theory, with these two things, 99% of cases can be solved. It’s a matter of time and degree of difficulty.

Soon, Director Wang took out the images of the first batch of personnel.

Jiang Yuan heard the noise and took the initiative to take a look. Sure enough, he saw two assistants brought by Director Wang, humming and arrogant.

Monitoring feedback is greatly affected by oneself and the environment. On the one hand, it is exposed to the outside. Wind, frost, rain, snow or haze will affect the clarity of the image.

Furthermore, the clarity of the surveillance picture itself is also limited. No metaphor is needed. The difference in image quality between 4k resources and 1080p resources or 240p resources is obvious to all. The monitoring equipment is being installed one after another. In some places, the blue control equipment that has been dry for 10 years is still in use. The investment in different places is also different, so naturally it cannot be generalized.

In addition, distance is also a decisive factor. With the same image quality, shooting a human body within 1 meter will definitely be different from that of a human body 100 meters away.

All of the above can be partially or completely solved using image enhancement technology.

Director Wang's body

As an expert in image tracking, he obviously attaches great importance to related issues. He brought a younger brother who worked hard and kept pulling out various frames and command lines. Among them, the one who was the main one seemed to be a technical expert at level 2 and above.

In the field of image enhancement, technicians with a technical level of lv2 are already extremely expensive.

As for the two technicians brought by Director Wang, the one with image enhancement technology at level 2 and above was obviously recruited from the public. Although the other one looks like he came out of the police academy, his image processing ability must be 5. .

The cost of raising such two people is probably more expensive than a squadron of police dogs.

Jiang Yuan patted the weaker technician on the right on the shoulder and said, "Give up your position."

He has been selling outside for a long time and has become very accustomed to dealing with people from other companies. Sometimes, when you use words to describe your abilities and skills, as well as the technical gap with the other party, the other party will often think that you are insulting him.

On the contrary, when the two technologies are actually put into operation, normal people tend to be very calm when the two technologies are compared side by side, which makes them extremely regretful.

The technician brought by Director Wang, who was equivalent to about one-third of the cost of a police dog squadron, stood up a little confused. He was not sure what Jiang Yuan wanted to do.

Jiang Yuan sat on his chair without hesitation and started to operate. One-third of the technicians from the police dog squadron were stunned and looked at Director Wang for help.

Director Wang actually noticed this and walked over slowly.

At this time, Jiang Yuan had officially begun the process of image enhancement. He had just observed one-third of the software used for dog skills, and after paying a little attention to the version, he easily got into the mood.

By the time Director Wang came over, Jiang Yuan had already processed every frame of the image.

This photo comes from a car rental company. It was recorded by surveillance in the parking lot. The quality of the image is average. You can distinguish faces, but it is a bit difficult to see them clearly and use them to identify people.

Jiang Yuan used the method of filling in noise and even enlarged the face.

"Is that okay?" Jiang Yuan saw Director Wang coming over and asked him politely for his opinion.

Director Wang is an expert in imaging and is naturally knowledgeable. He lay down in front of the computer and looked at it for a while, and couldn't help but look at Jiang Yuan: "Do you know how to enhance silent images?"

"I'm pretty good at it," Jiang Yuan said, suddenly calling up the command line and typing in a row of functions - in fact, there was no need at all, just to prove the strength of image enhancement lv5.

The expressions and attitudes of Director Wang and his two assistants made people feel suddenly very soft, like strong men who had eaten lv5 dog food.

"Let's work hard to fix the images of all the members of this gang." Jiang Yuan was like a naval captain who landed on a pirate island and started counting heads.

Dong Bing, the only female police officer at the scene, suddenly said in a voice that only Tang Jia could hear: "Ningtai Jiangyuan, no wonder."

Tang Jia rolled her eyelids and thought to herself: How could a policewoman use such a loud voice?
