Chapter 789: Running Map (Asking for Monthly Votes)

"I'm here with the leaders of the Zhengguang Bureau's anti-narcotics detachment. I'm on speakerphone." Jiang Yuan told Pang Jidong on the other end of the phone, then turned on speakerphone and placed the phone in the center of the conference table.

"Okay, Master." Pang Jidong replied quickly, and then said with a smile: "Hello everyone, I am Pang Jidong from the Fourth Brigade of the Luojin City Criminal Police Detachment."

"Hello, Pangda Team, I am Lao Shi, Shi Zhonglong, from the anti-drug detachment. We should have met before, haha..." Shi Zhonglong really went to Luojin City to arrest people, and stayed there for a while. , have impressions of several captains in Luojin City.

Looking up at Jiang Yuan, Shi Zhonglong was curious and opened the topic, saying: "Team Pangda, when did you become a disciple of forensic doctor Yu Jiang?"

"It's been a year since I became a disciple. Master taught me to be very serious. I came to the capital again a while ago and studied with Master for more than a month." Pang Jidong introduced it with a smile, but it was not complete. , he didn’t know what was going on on the other side, so he naturally wanted to help his master hold up the situation.

The captain of the anti-drug detachment and others quickly said hello.

At this time, Shi Zhonglong and others were finally convinced that Jiang Yuan was really Pang Jidong's master, and that he was a formal apprentice and had learned from it.

Within the police community, it is relatively traditional. This kind of master-disciple relationship can be said to be very common and respected.

People in the room looked at each other, smoking cigarettes and looking at Jiang Yuan's face, all lost in thought.

Ningtai and Jiangyuan are too far away!

Snapped.

Jiang Yuan took out a cigarette, preparing to resist the erosion of second-hand smoke. He lit the lighter but did not light it.

Shi Zhonglong quickly picked up the lighter in front of him and helped Jiang Yuan light it.

Jiang Yuan smiled and nodded to Shi Zhonglong, and then said to the mobile phone: "Jidong, we are now going to track down a drug buster, nicknamed Niu Er. The last information found now is that he called the woman from Luojin City. Friend, we have his location when he made the phone call. Let’s see if it’s convenient for you to trace..."

Niu Er ran away in a hurry and left a lot of goods and money at home and at his girlfriend's house. Niu Er called to ask his girlfriend to help hide the goods and send money.

As for whether his girlfriend was under police surveillance, he couldn't care less at the time.

This was also Niu Er's last message. After that, Niu Er disappeared without a trace, and he probably had a new identity.

Pang Jidong listened carefully to Jiang Yuan's explanation of the case and said, "It's simple. I'll tell the detective team first, and then go to the command center. Our images are now compiled..."

The Luojin City Criminal Police Team is at the detachment level, and the attached picture detectives are also at the brigade level, similar to those in Changyang City. In contrast, the criminal police team in Ningtai County only reached the brigade level, and the picture detective had only one imaging office with a total of three people.

Jiang Yuan hung up the phone first, then spread out the outstanding file on the spot and started reading.

Li Qian, the leader of the anti-drug detachment, thought about it and stayed. After finally contacting Luojin City, he also hoped to uproot the coconut meat line. Heroin's circuit is more traditional than new drugs. If it can be knocked out, it will be difficult to recover in a short time. When it recovers, drug dealers will also have to pay a higher price.

Cui Qishan coughed twice and took up the task of communication.

When a group of people gave the conference room the feeling of a wonderland, Pang Jidong's phone call came back, and then several technicians took the call and started tinkering.

Soon, the large monitor in the conference room of the Anti-Narcotics Detachment was synchronized with the screen content of the Luojin City Picture Detective Brigade.

"Master, look at the surveillance video at what time and place you want to check." Pang Jidong was already familiar with Jiang Yuan's style of play and knew that what he needed most now was video resources.

Jiang Yuan looked at Captain Shi.

Shi Zhonglong quickly reported the time and place.

The picture detective of Luojin City pulled up nine consecutive screens and said: "This is a video of the vehicle bayonet and portrait bayonet at the main street entrance in Wufeng area. I just ran through the portrait, and I didn't follow the leader. Consistent.”

The portrait mount camera takes very clear pictures, almost the same as ordinary mobile phone face shots. On sidewalks, intersections, etc. that pass through checkpoints every day, people will take pictures when they pass by. If ordinary people don't pay attention, they will definitely be photographed.

As for the situation where you pay special attention to the situation that you can't take the picture, you should naturally pay more attention.

"Run a group of faces wearing masks to see." Jiang Yuan looked at the software model used by Luo Jin City and began to issue an order.

The picture detective from Luojin City on the other end of the phone responded, quickly pulled out a large number of images, and said: "There are 2,720 images."

"Add one wearing sunglasses. Wearing a mask and wearing sunglasses at the same time." Jiang Yuandao.

The photo scout in Luojin City did as he was told, and this time there were only more than twenty photos.

Jiang Yuan and others looked at them one by one and unfortunately found that none of them matched the ear.

Pang Jidong took the initiative at this time and said: "Otherwise, we can organize people here to check these 2,720 pictures to see if there are any suspected cow ears?"

"Okay. That's hard work." Jiang Yuandao.

"It's okay. The detachment leader said that Team Jiang is dealing with serious cases, and he specifically asked us to devote ourselves to it." The person who spoke this time was the policeman from the detective brigade.

On the other end of the phone, everyone from the Anti-Narcotics Detachment of the Zhengguang Bureau looked at each other, and their expressions became serious.

There is a saying that is right. Jiang Yuan has done so many serious cases and it is absolutely right for him to cooperate well.

"OK, it's arranged. We have formed a review team. It will take about an hour, and we should be able to get results." The captain of the image detection team explained in person over the phone.

Jiang Yuan thanked him repeatedly.

Wearing a mask, it is impossible to compare directly, but the effect of manual search is still quite outstanding. The most important thing is that finding suspects does not need to be extremely accurate, just find those who are roughly similar.

When there are fewer suspects, you can conduct special investigations, or even door-to-door investigations.

This is a huge difference between theoretical investigations and actual investigations. Theoretical investigations always want to find the "only solution", but actual investigations do not have so many twists and turns. If there are six or seven points of similarity, they will come to the door. For cases that have a little bit of content, it is normal to hit the jujube and no jujube.

"Then let's continue and check the vehicle checkpoints." Jiang Yuan has LV6 image detection (trajectory analysis) technology, and his ideas are one set after another.

"Then let's run a car with no license plate, fake license plate, blurred license plate and temporary license plate first?" The image detection in Luojin City habitually gave suggestions.

"Okay." Jiang Yuan also waited for a while.

Some people pretend to be smart and will cover the license plate with mud and water. For license plates like this, as long as they pass the vehicle checkpoint, they will directly call the police. The traffic police would not watch the video originally, but in order to remove the little red dot, they have to click on it to see it.

The most conventional image detection did not come out, Jiang Yuan added: "Pull out a batch of vehicles with unclear faces, including the co-pilot's vehicle."

"Okay. In this case... 48,568 pictures." The image detection person reported.

Jiang Yuan rubbed his chin. This is what big data is like now. There is an explosion of data. How to process and extract data is the core.

"Add a detour." Jiang Yuan said: "Vehicles that have passed the same place many times, on the same day, see which ones there are."

With the caution of drug dealers, whether they drive themselves or let the driver drive, it is unlikely that the car will get off directly after arriving. They will always look around.

This time, the image detection pulled out much fewer vehicles, only 7.

The image detection released them one by one for inspection.

"That's it." Jiang Yuan only looked at it for a while and confirmed Niu Er, and said: "Track this black Sonata! The last number is 778."

"Yes." The technician of the image detection was also very excited. He pulled up the video and began to track the black Sonata.

Soon, the Sonata left the avenue and entered a small alley.

On the image, the car disappeared.

The image detection in Luojin City is also professional. According to the route, he quickly retrieved the surveillance video of the black Sonata two kilometers away.

"He came and left again." Jiang Yuan looked at the time and said: "Niu Er should have gotten off here. He also made a phone call."

"At the time of the call, the car had already left Wufeng." The image detection in Luojin City locked the car and could retrieve the time when the car passed each checkpoint, and even directly draw a trajectory map on the map by software.

But if you get off halfway, everything will have to start all over again. This made several image detection personnel feel a little frustrated.

Jiang Yuan was unmoved. The suspects in some cases are obviously more alert, but from his point of view, it is just a more interesting resistance.

Jiang Yuan said: "Niu Er is so cautious, and he made a phone call here in Wufeng. He should not live here. Look for single-person vehicles within 1 hour after 10 minutes of the call. Including those with obscured faces."

The picture detective operated and produced more than 1,300 pictures, but there was no harvest.

Jiang Yuan pondered for a moment and said: "In this case, he should have left on foot or by bike."

"The photos of the checkpoint include this side." The police officer of the picture detective reminded that the previous 2,720 pictures had just been read.

Jiang Yuan shook his head and said: "He should have taken a small road. He may not know where the checkpoint is, but he should be able to bypass it by taking a small road."

"There is no record showing that he is familiar with the area." One picture detective couldn't help but express his objection over the phone.

In the process of investigating a case, no matter how big or small, especially for serious cases, leaders at any level actually don't care about the "offensive" remarks of their subordinates. Because for a case of this level, there may not be enough clues, so adding one or two more investigative directions is not a problem at all.

Moreover, while experience in case investigation is important, the unfixed thinking of young people is also important. Professional investigators are aware of this.

At most, if the investigative direction proposed by the young people is difficult, they can be sent to investigate, such as searching septic tanks, climbing garbage mountains, etc.

Jiang Yuan did not care about the rebuttal of the young policeman on the opposite side, and only said: "Niu Er is a drug dealer, and he does not use his ID card and mobile phone on a daily basis. It doesn't matter whether there are records or not... We are now considering the time issue first, because Niu Er is on the run, and the core of his concern should be the time issue. Unless it is necessary, I believe he will not waste time."

Jiang Yuan said this, clicked a few points on the map, took a screenshot and sent it to Pang Jidong, saying: "Find the surveillance of these places. If there are missing ones, find the surveillance of other units, or civilian surveillance."

"Okay, I'll send someone here." Pang Jidong agreed.

Jiang Yuan then opened a larger map and marked more than thirty points on the outer circle. After a while, he removed half of them.

"If you can't find it, the second batch will look here."

Jiang Yuan was using Level 6 trajectory analysis. Although he had very little information, he was still very confident.

The criminal police and drug enforcement officers on both ends of the phone were infected by Jiang Yuan's confidence and smiled optimistically. Only the professional map detective was full of questions: It was fine just now, why did this map suddenly pop up?
