National Forensic Doctor-Chapter 913 - 851: That’s Reasonable

Jiang Yuan was operating the mouse, comparing the fingerprints scanned by the software one by one, when he looked up at the living room and said politely, "Um... Captain Li and Captain Liu, please have some tea and take a break, it’s okay, you can check your phones. It’s mainly because I’ve run into a bit of an issue here, I think it’s better to have you local police officers here."

The two officers immediately straightened their backs on hearing Jiang Yuan’s words.

Liu Ling said, "Captain Jiang, no worries, you go ahead with your work. Just give us a shout if there’s anything... Eh, do we have a case?"

"Yes, just came across a case. I didn’t bring anyone with me, so if you two could help out for a while, that would be great." Jiang Yuan paused and then added, "By the way, did you bring your guns?"

The smiles on their faces visibly stiffened.

In China, it’s not as exaggerated as in Japan, where a career in the police is honored by not using a gun, but speaking of regular officers, how many have actually drawn a gun since the year 2000? And how many have fired one?

In county-level places like Su Island, let alone the local police, even the criminal police don’t get a chance to fire their guns all year round.

Originally, the duo Li and Liu had just come to deliver a gift and greet Jiang Yuan before leaving, but now...

Their eyes frantically communicated, fearing they themselves were about to become the gift.

"If you have things to do, you can play on your phones, but it would be better not to communicate with the outside world, including Director Kong. Don’t cause him any trouble either."

What Jiang Yuan said was half true and half false. If the case were to be concluded smoothly, then naturally everyone would be happy. But if any information were to leak and someone got away, then from this moment on, any calls made or messages sent by the two officers would be subject to scrutiny.

The discipline required by the disciplined forces is always very serious. The two officers quickly sat up straight and agreed.

Technically, they could choose not to listen to Jiang Yuan, but neither of them even considered that option.

Jiang Yuan didn’t have much else to say and turned his attention back to finding work opportunities for the colleagues who had flown in.

There were over thirty fingerprints on the fan. Jiang Yuan scanned them once, classified them, and then selected some for marking the points of identification, eventually categorizing them into seven individuals.

For a novice fingerprint analyst, marking one fingerprint and its features might take fifteen to thirty minutes, and a Level 1 experienced elite might be faster, perhaps taking around ten minutes. The difference is that the markings made by a Level 1 analyst would be more accurate and reliable.

In other words, just marking the fingerprints on one side of the fan would take a regular fingerprint analyst a day or two of work, and actually, even more, because inevitably some fingerprints would be difficult to identify and mark.

That’s also why in regular cases, most of the fingerprints collected are key fingerprints, such as those on the weapon, tools, car handles, window sills, and door handles, etc.

Extracting every fingerprint at a crime scene would mean endless work for most forensic teams.

But for Jiang Yuan, halving over thirty fingerprints for classification was straightforward. In fact, many duplicate prints had already been excluded from the count of over thirty.

When it came to marking the minutiae, a complete fingerprint for Jiang Yuan was as simple as an elementary school mental arithmetic problem; he worked as fast as his eyes and hands could scan.

The entire process of extracting the fingerprints from the fan took Jiang Yuan just half an hour. On average, each print took about two minutes. Even so, this was usually work that Jiang Yuan didn’t need to do himself.

The fingerprint matching phase, however, involved a bit of luck and pseudo-science.

However, there was nothing tricky about these fingerprints...

Although the owner of the fingerprints was indeed quite a character.

As Jiang Yuan had expected, one of the three young ladies had indeed been impacted, and impacted three times at that, averaging one incident per lady.

This is what they call the broken windows theory, once a person gets caught once, they get hit once, they are likely... not to fear the strike itself so much anymore—this is also one of the secondary disasters brought about by the criminalization of DUI.

And, looking at it with Jiang Yuan’s way of thinking, the three ladies being bossed around by the photographer to make videos, even if their business model is a bit different, can be considered pretty familiar with one another.

With this thought, Jiang Yuan picked up his phone again to call the office of the Cold Case Squad.

"Captain Jiang?" Tang Jia was currently in charge at the center.

"Yeah, I’m sending another person your way, a prostituted woman; see where her main area of work is, contact the local public security police to find out more. Yeah, give her a call, tell her to report to Ningtai County Bureau. Also, I’ve got three more people for you, two of whom are suspected prostitutes and one a pimp; get together with Technical Investigation and Cybersecurity, etc., to check them out, mark down the times and places where these three appear together."

As Jiang Yuan spoke, he sent over the people’s information to Tang Jia.

Jiang Yuan often handled cases in a straightforward manner because he consistently exceeded technical indicators in his work.

This time, Jiang Yuan played it straight. In his view, if the photographer Wang Haoyu was dabbling in drug trafficking, and also running this unprofitable photo studio, even if he were a time management master, the time he could dedicate to his pimping business would be limited.

Since the time was limited, the number of ladies Wang Haoyu could control was certainly not extensive.

And if he intended to use his job to entertain his own supplier well, gathering all the ladies under him to offer the guest more choices, it was very likely.

The two people sitting in the living room exchanged a silent glance; they had to submit a report in advance whenever they wanted to use Technical Investigation and Cybersecurity while they were stationed at the police station.

Shortly after, Tang Jia called back: "There are confirmed to be over a dozen locations, should I send them to your phone?"

"A dozen locations? Across several provinces and cities?" Jiang Yuan was a bit surprised. This photographer has quite a close relationship with the three ladies. Looking at it this way, it’s somewhat insulting to keep calling him a pimp—hanging on the edge of organized prostitution, there’s a difference in sentencing from 2 to 7 years.

"Three provinces, five cities," said Tang Jia.

"Hmm..." Jiang Yuan pondered for a moment, then continued, "Alright, report this to Commissioner Huang, then go to the Narcotics Squad, and ask them for information on new drugs during this time, especially the type of bulk drugs I sent you, about the frequency and such. Have them compare it with the times these people appeared."

Jiang Yuan deliberately avoided mentioning anything like popping candy.

The two in the living room were even more bewildered, only knowing that Jiang Yuan seemed to be preparing to mobilize the Narcotics Squad again.

At this point, they were getting a bit restless. After all, they truly didn’t bring their guns!

Tang Jia quickly jotted down notes on the other end of the call, then asked, "After the comparison, should I send you the results?"

"I want cases with leads; if there are corresponding cases at the respective times and locations, just send me the case numbers."

"Understood."

Tang Jia now understood that Jiang Yuan was linking a series of cases together in this way, effectively combining a series of drug-related cases with the three prostituted women and the pimp.

This method is a highly efficient mode of solving cases, albeit with considerable difficulty.

Of course, if the entire case can be completed in this manner, it would also be a model of high completion because the number of cases solved would increase, the amount of drugs and money involved would grow, the facts of the case would become more comprehensive, and the most direct effect would be that the death penalty rate for those involved would greatly increase!

Jiang Yuan then put down his phone, smiled at the two police officers, stood up to pour them tea, and bluntly said, "This might be a series of cases, thank you for your hard work protecting me this time; I’ll make sure you are commended for this."

Liu Ling replied subconsciously, "No need, no need..."

"What are you talking about?" The other officer quickly interjected, then turned to Jiang Yuan, "Thank you, Captain Jiang, we will surely stand our post, as long as we’re here, the position holds!"
