Chapter 970

Task progress: 245 people arrested.

Task progress: 256 people arrested.

Jiang Yuan leaned on the sofa, watching the task progress numbers popping up, and felt his mood was quite good.

It felt just like receiving passive income.

For the same amount of money, if the source is rent, it's more valuable than money earned from 996.

It's also the arrest of over 200 people; if it's someone else catching them for you, you'll feel very relaxed.

Jiang Yuan couldn't help but stretch and yawn, as if he had returned to that hot afternoon, helping his old man collect rent, running through several buildings in a row, feeling both hot and sleepy.

"Team Jiang has been tired for a day. Do you want to take a break?" The cadres of the Beijing Bureau have always appeared exceptionally understanding.

Jiang Yuan smiled and waved his hand, saying: "No rush. The front line might still need to send a lot of evidence over; I'll rest after looking at it."

Danda is an enterprise that came ashore early; before it was exposed, no one knew how much filth was inside. Even now, everyone actually doesn't know very clearly.

Even Jiang Yuan and the others could only confirm through Old Piao that Danda's chairman, Lü Qiang, was involved in instigating murder, but the fact that Old Piao was caught itself carried a bit of probability.

Furthermore, if it were just Piao Li alone, a lot of work would have to be done to topple Lü Qiang. So don't look at Piao Li as an old man who started as a thug; he knows the ropes.

It requires a criminal police officer like Jiang Yuan, who has criminal investigation capabilities, administrative strength, and fame, plus supportive leaders, to successfully handle this case—each is indispensable.

If there were no supportive leaders, the search and blockade of Danda would be hard to approve, and if there were no criminal police officer like Jiang Yuan with criminal investigation capabilities, the leaders couldn't rush in to solve the case themselves; without solid evidence and case files, the case couldn't be handled.

And below Lü Qiang, whether there exists a criminal deep-water zone within Danda that doesn't even communicate with each other is hard to say. Some people might really stop doing dark things after coming ashore and washing clean, but some people might have path dependence, either actively or passively, and might even restart the methods of the past.

As for the business wars of 10 years ago, Danda's executives might not necessarily use any high-end tactics; in the end, they might just return to simple and unadorned operations.

For these potentially existing cases, as long as you find the end of the rope, you can still solve them.

For example, these arrested Danda people must first have their DNA and fingerprints collected, and in terms of numbers and probability, there will always be someone who slips up in some cases.

Besides this, like the reason Old Piao was caught, the same weapon used, or other similar tools involved in the case, all have the possibility of being linked to some cases.

While speaking, photos began to be transmitted to the backend.

The dozen or so criminal science personnel Jiang Yuan had prepared immediately entered a working state.

Those who do criminal science all know that evidence is like a cockroach; when you find one, there is a four-generation, three-duke-level big family waiting for you.

When criminal police collect evidence, they absolutely won't just collect one piece. The reality is, if there is really very little evidence at the scene and only one piece needs to be collected, they will scrape a layer off the poop in the trash can for physical and chemical testing.

But if there is really a lot of evidence at the scene and a lot needs to be collected, they often miss some, or simply pack the whole room back, or even put multiple pieces of evidence mixed together in one evidence bag.

Therefore, now, larger police teams, or small police teams facing major cases, all send their own criminal science team members to collect physical evidence themselves. The main idea is clear responsibility.

Jiang Yuan looked at the fingerprints first.

Fingerprints and DNA are the most direct evidence pointing to a person. DNA still needs a few hours to produce results, while fingerprints are relatively fast and also quite particular.

Jiang Yuan participated in the fingerprint battle in Changyang City back then, using existing fingerprints to solve old cases.

The principles are all the same; newly collected fingerprints are full fingerprints, with ten fingers rolling back and forth on the instrument, exposing all fingerprint information before stopping.

As everyone knows, fingerprints left at a crime scene can only be a part of the fingerprint. When trace examiners face such fingerprints, drawing the characteristic points of the fingerprint and waiting for the system to match is the most conventional practice.

But for newly collected fingerprints, correctly marking the characteristic points is actually just as important.

So-called fingerprint matching, those who don't understand think it's a magical image comparison technology; in the end, it's still mainly numerical comparison.

In short, this is a two-way effort. It requires the people in charge of fingerprints on both sides to do their best for it to be easily matched.

And everyone knows that there are about 100 characteristic points on a fingerprint.

Very few technicians will mark so many characteristic points for newly collected fingerprints.

One is that time is limited, and the other is that technology is limited.

Some characteristic points are just very difficult to determine and mark, and they often get messed up. Full fingerprints aren't necessarily easier to mark than residual fingerprints collected from the scene.

In the final analysis, these technicians responsible for marking fingerprints are also mainly entry-level players from LV0.5 to LV1. In this environment where the whole society is talking about "how much money you get for how much work you do," one cannot expect a new police officer with a monthly salary of 5,000 to show amazing creativity and sense of responsibility.

But Jiang Yuan is truly someone who can mark 100 characteristic points.

And he doesn't feel much of a burden.

This is equivalent to marking 100 special points in a picture. People who haven't been trained, even if they are very serious, will find it very hard to mark and are prone to errors.

But if trained, especially if trained particularly well, this is just a craft.

In this way, every time Jiang Yuan marks a person's fingerprint, it is equivalent to marking 1,000 characteristic points. Using 1,000 characteristic points to run the database, the probability of a match is relatively high.

Actually, it won't be particularly high, because as long as there are 8 characteristic points in the database, it will pop up; if needed, even those with 6 characteristic points will pop up. Jiang Yuan just increased this probability.

However, in such an environment, when the first suspect finished marking and a match immediately popped up, Jiang Yuan still had to praise: "Count yourself unlucky!"

Count yourself unlucky * 2!

Count yourself unlucky * 3!

The continuous matches made the atmosphere in the conference room become heated.

Even Jiang Yuan actually didn't expect that there would be so many matched suspects.

"This Danda, there are quite a lot of criminals." When Jiang Yuan matched the fifth one, he was already a bit tired, but to be honest, he had only marked 12 suspects so far.

"There are quite a lot of small cases matched; maybe they weren't taken too seriously before." Because of Song Tiancheng, Tao Lu sat nearby watching and added: "Small cases from many years ago, which weren't solved back then, weren't handled later. Back then, they didn't get their fingerprints or anything, letting them slip through."

"That's how it is after washing clean; you have no reason to take their fingerprints." Song Tiancheng nodded, skipping over this story.

Tao Lu smiled: "Fortunately, now that these cases are confirmed, we can use these cases to drag them out again."

"En, these people have been living in luxury for too long; they should be unwilling to go to jail." Song Tiancheng said, looking at his phone, and said: "Let the economic investigation team intervene."

"Yes." Tao Lu immediately agreed. In this way, the jurisdiction of the case will also be more convenient. Tao Lu then asked: "Should we issue an announcement?"

The announcement was written in advance. For a listed company, naturally, there must be preparations.

Song Tiancheng nodded: "Issue it. I don't know if the stock price will avalanche."

An hour later.

The police officers from the economic investigation detachment arrived at the conference room in a mighty force.

At the same time, Danda's stock also successfully climbed to the daily limit.

Bad news is out, all are good news—Danda pure enjoyment version.
