Chapter 1145: Identifying Wealth

Jiang Yuan determined the plan, wandered around the commercial street of Weight in jin Road a few more times, finally selected the commanding height on the east side, and then asked people to take back the videos of more than a dozen monitors at the beginning and end of the street.

Other monitors on the same street are also needed, but with these dozen monitors, people coming and going on this street can basically be seen.

As for whether the criminal rarely comes to this street, or even because of some reason, simply doesn't come to this street, that means... that means Jiang Yuan and Liu Jinghui's analysis is a big failure, and the Dragon Knight combination can only start all over again.

"Start."

In the image investigation analysis room of Lanyue City Bureau, Jiang Yuan found a chair and sat down comfortably, holding Wei Shiyan's freshly brewed emerald manor sun-dried coffee in his left hand, and his own ranch-produced American Texas smoked beef sandwich in his right hand. Half is work, half is life, behind is the leader's expectation, and the back is the criminal police's dream.

The area of the image investigation analysis room is much smaller than the command room, but small has its tightness, and it is more comfortable to move in and out.

Wang Chuanxing stepped forward, pushed Jiang Yuan's chair back slightly, adjusted his line of sight to just right, and nodded to the image investigation police next to him.

12 screens lit up together, synchronously displaying

Jiang Yuan rarely looked at so many screens at once, but this time... the 12 screens were actually displaying a single surveillance feed.

A single surveillance feed, spread across 12 screens, wasn't just a simple magnification; it highlighted certain characteristics of the crowd. Half of the screens displayed the feet of the crowd under surveillance.

The first set of surveillance footage released by image investigation captured thirty or forty people at a time. When the feet of these people were magnified onto 6 screens, each screen could still be assigned several pairs of feet.

Besides this, wrists, heads, faces, and so on were also moderately magnified.

The footage on the screens played at a steady speed. Jiang Yuan took a bite of his meat sandwich and a sip of coffee, watching leisurely. This task was clearly going to take a long time, so there was no need to rush.

Liu Jinghui also sat nearby to watch. In situations not involving information like surveillance locations, he also had a certain ability to make judgments just by looking at the footage.

Wei Shiyan also held a coffee, squatting behind Jiang Yuan. Once Jiang Yuan finished a cup, he quickly refilled it and asked the question he had been holding in his heart for a long time: "Team Leader Jiang, I want to learn from you. How exactly are you looking at this?"

As soon as this question came out, the ears of the image investigation officers nearby pricked up.

Jiang Yuan's technical reputation was widespread; being able to learn even a little bit would be enough for most people to make a living.

Jiang Yuan had never been shy about teaching others his techniques, and even intended to spread them. Although he was in work mode, he wasn't very busy, so he said: "That's a long story. First of all, look at the clothing. People rely on clothes and horses on saddles. Of course, some people might be rich but dress very ordinarily—we'll set that aside for now. But if the clothes they are wearing are very expensive, that can be considered within the scope."

"LV, Hermes, and the like—a T-shirt costs thousands or tens of thousands, a jacket twenty or thirty thousand... However, many rich people nowadays don't like clothes with big logos. High-end custom pieces are hard to spot, right?" Wei Shiyan actually knew a bit about this area, and his interest suddenly increased.

Jiang Yuan nodded slightly and said: "Looking at high-priced clothing isn't for exclusion, but for screening. If you find that the clothes this person is wearing are far beyond the consumption level of an ordinary person, then first assume he is a drug dealer."

"Understood." Wei Shiyan said, looking at Jiang Yuan's clothes with some curiosity: "However, I see that many men don't really understand clothing accessories and such. You seem quite familiar with them? Did you practice by spending money?"

Liu Jinghui coughed hard twice from the side, looked at Wei Shiyan helplessly, and said: "Jiang Yuan is a forensic expert."

"Forensic experts understand clothes? Oh, right, forensic experts have to describe the clothing of corpses." Wei Shiyan felt a bit embarrassed, but resisted it with his Kshatriya-like talent.

A forensic expert's appraisal report includes a description of clothing. For example, the deceased was wearing an "Old Dog" brand T-shirt, with a dog head on the chest, and the five words "Old Dog, pay with your life" written on it...

Additionally, during the investigation stage, a forensic expert's appraisal of clothing can often play a role. For example, the degree of wear on clothing can largely explain the deceased's habits and economic status before death, whether the clothing coordination has a sense of fashion, whether there are accessories matched by the opposite sex—such as whether there is a wedding ring on the finger, a lover's pendant around the neck, or a girlfriend's hair tie on the wrist, etc.

However, Jiang Yuan's technique mainly came from his inheritance. He had LV2 Trendy Clothing Taste, LV2 Cosplay, LV2 Tailoring, LV2 Japanese-style Makeup, and LV2 Used Clothing Appraisal.

Among these, the most useful one was actually the last one. Used Clothing Appraisal doesn't talk about styling, fashion, personality, or self-expression; it is a very pure skill for judging the price of a piece of clothing, with a side function of judging authenticity.

With this set of skills, when Jiang Yuan glanced at the people in the video, he couldn't definitively judge that someone wearing less than ten thousand yuan didn't have money, but for those wearing more than ten thousand yuan, he could pay extra attention.

Turning his head, Jiang Yuan added: "Another point: if the material of the clothes on their body is too cheap or obviously doesn't fit, you can also judge that they are not the target person."

"I understand this. Drug dealers have money, so they might not buy very expensive brands, but at least they will buy comfortable clothes." Wei Shiyan hesitated, then added: "But if they are addicted to drugs or something, would they be insensitive to clothing?"

"If the drug addiction has reached that level, it should be noticeable. You can just list them separately as well," Jiang Yuan said.

Liu Jinghui said from the side at this moment: "A level 5 drug dealer handles at least several kilograms, or even over ten kilograms of drugs per month, with an income of at least several million to tens of millions. With so much money, if it were all cash, it would be difficult for one person to move it, and they still have to pay the suppliers or the drug manufacturing factory. It's unrealistic for them to live in urban villages like small-time dealers. Even if they were like Brother Li Si and his group, it's impossible for him to live alone, let alone shop for himself every day and specifically buy cheap clothing."

Liu Jinghui summarized: "The other party either tries on clothes themselves and has their own preferences, or someone caters to their tastes. Being rich and still suffering—that's too niche."

"It's not necessarily that they aren't valuable; it could be that they are detrimental to physical health, or obviously uncomfortable to wear. You can pay more attention to shoes for this point. Even if they are wearing slippers, some rubber shoes are really hard to wear, and it's even more impossible to wear shoes that obviously don't fit." Jiang Yuan's research on shoes was much higher than on clothes; knowledge of shoes is indispensable in footprint appraisal.

In fact, the domestic database for shoe prints or sole patterns has been under construction and supplementation. What kind of shoe prints should be left when shoes of different materials step on various surfaces, or what kind of wear different soles will have—these are all problems that footprint experts need to consider.

Some classic cases solved through footprint appraisal were broken based on the type and wear of the soles. Some very powerful footprint appraisal experts are rooted locally and will even learn about all the shoe styles currently on sale locally, to the point where they can immediately name the brand of the shoe upon seeing a shoe print at the scene.

Even after entering the internet age, some people still maintain this habit, and it often has miraculous effects. Perhaps because people who like contact-based crime also like contact-based shopping. And young people who like online shopping also like online crime...

"Besides clothes, skin, teeth, and hairstyles can also be taken into consideration." Jiang Yuan pointed to a person in the footage and said: "Everyone is familiar with the appearance characteristics of drug addiction, such as meth sores. But if it's a non-drug-using population, the skin, teeth, and hairstyle of someone earning millions or tens of millions a month won't be too bad, because money can fix it."

Liu Jinghui added: "Especially if they want to live a wild life, managing their appearance is necessary. Hmm... right in front is the film and television city, so the related supporting facilities must be plentiful. Regardless of whether this drug dealer is male or female, there are plenty of related agencies to help them spend their money."

"If they earn tens of millions a month, there must be people around them helping them think about these things. Even if they don't have a partner, they must have a few mistresses they can't get rid of." Wei Shiyan nodded with great understanding.

"Then there are things like their gaze and gait, which can be used as a reference," Jiang Yuan said, then added: "This is the first pass of consideration."

Wei Shiyan: "There's a second pass, a third pass?"

Jiang Yuan nodded: "We assume this drug dealer appears in the vicinity multiple times. Therefore, if a person cannot appear multiple times, they are not the target person. In addition, when appearing multiple times, the clothes, shoes, and even hairstyles and accessories they wear should be different..."

Wei Shiyan's eyes lit up as he listened: "Judging by this, there really aren't many people left."

"Not slow, not slow." Yuan Bomin shook his head repeatedly and hesitated: "I still don't quite understand..."

"Image investigation looking for people or cars is not looking along the cameras all the way. You see a car going east. You actually don't need to keep confirming where this car has gone. Just look for this car at the nodes of the only way to the east. In fact, most of the time, this work is done by computer software."

Jiang Yuan explained his understanding of gait analysis slightly, and Yuan Bomin's face suddenly became vivid.

"I will organize the team to catch people!" Yuan Bomin said with a smile: "If you had said it directly just now, we would have caught people by now."

"I suggest not catching people first. Or catch one or two selectively, just to confirm the identity of this Fat-Wrapped Muscle." Jiang Yuan stopped Yuan Bomin and added: "Most people, don't move for the time being, just remember them."

Yuan Bomin hesitated and said: "If the Fat-Wrapped Muscle you mentioned is not Li Si Ge, maybe he also knows where Li Si Ge is?"

Jiang Yuan: "Horizontal understanding is difficult. Wait a moment. After I confirm the upstream of Fat-Wrapped Muscle, maybe he can find Li Si Ge!"

Wei Shiyan suddenly felt a lot; it was the first time in his life he felt that doing something was so difficult.
