Chapter 144: Enough Cases

Monday.

Ningtai County is raining.

Abundant rainwater travels from south to north, from east to west, turning the outside of the window into a marshland.

Wu Jun leaned against the windowsill, smoking Yuxi alone, and said slowly: "If someone dies today, we will be in trouble."

Jiang Yuan raised his head from behind the computer screen and said: "It won't be that coincidental."

"Don't say coincidental words." Wu Jun waved his hand and said: "If you say coincidental, it is really easy to be coincidental. Thinking back then, we encountered a case like this..."

Wu Jun then told Jiang Yuan about the past.

Jiang Yuan looked at the training materials on the screen silently.

In terms of fingerprint identification, his understanding is also constantly improving.

However, criminal science and technology are a bit different from ordinary science or technology, in that they are very dependent on external support.

It is probably because the police do not pay attention to fighting alone, and no one has ever considered creating a technology that allows the police to use it single-handedly.

On the contrary, criminal science and technology often require the cooperation of companions, and even the cooperation of a whole system.

Like fingerprint technology, no matter how strong Jiang Yuan's identification ability is, it is dependent on the fingerprint library.

And the fingerprint library is actually accumulated bit by bit.

From Jiang Yuan's point of view, what is currently restricting the further development of fingerprint technology is the construction of the fingerprint library, as well as the entry and annotation of new fingerprints.

This point also requires the cooperation of the entire police system.

In terms of criminal science and technology, it is usually reflected in various trainings.

Explanation of the latest technology, promotion of relatively novel technology, use of relatively mature technology...

The police system is perhaps the unit that likes to engage in training the most in the country. Even so, the grassroots strength of the police system is still weak.

And entering fingerprints is not just something that can be solved by long-term work; it also requires more meticulous work arrangements and the dissemination of work methods.

At present, it seems that the system will not give this kind of management skill.

Jiang Yuan tried to learn it himself.

Bang.

Wei Zhengguo rushed in from outside the door.

"Did someone die?"

Jiang Yuan and Wu Jun turned their heads together and shouted in unison.

Wei Zhengguo looked behind him cautiously, thought carefully for a while, and said: "No... no one died."

"Oh... I said so, it's okay..." Wu Jun breathed a sigh of relief, stopped smoking, and hurriedly sat back in his position, touching the Guan Gong statue and remaining silent.

Jiang Yuan looked at Wei Zhengguo and smiled: "Captain Wei, what's the matter?"

"Oh, that, Li Suigong is back, bringing the criminal suspect of that fraud case." Wei Zhengguo breathed a sigh of relief, smiled and said: "People have been sent to the case-handling center."

Jiang Yuan looked outside in surprise: "At this time? Did they stay up all night to catch him?"

"More than that, they have been running for three days. I just found out that the bayonet in Qilu Province alarmed, and Li Suigong shouted for people to go, 1200 kilometers one way, 2500 kilometers round trip. They also squatted for a day in the middle." Wei Zhengguo shook his head and praised: "Economic investigation is also not easy to do."

"Then let's go see." Jiang Yuan got up hurriedly.

Entering the case-handling center, he saw Li Suigong and another police officer filling out forms, and the colleague next to him had already fallen asleep on the sofa.

There are not many people in the case-handling center, but there are always people coming and going, and Li Suigong just pretends not to see.

"Captain Li." Jiang Yuan greeted him busily.

"Brother Jiang." Li Suigong hurriedly held Jiang Yuan's hand. He went to Qilu Province because of Jiang Yuan. Now that he is back, of course, he wants to sell well.

"Don't be so polite. I heard you caught someone back?"

Li Suigong nodded heavily, and then said a bit embarrassedly: "We followed the line of people, didn't expect that this guy had already transferred the money. The final recovered funds might be less than 300,000."

He actually knew that it was impossible to fully recover the money. Moreover, don't look at 800,000 being a lot for ordinary people, various capital channels are not for ordinary people. So, from the beginning, Li Suigong didn't pay attention to where the money went.

After catching the person, he asked and looked, and sure enough, only more than 200,000 were left.

The rest of the money, some was squandered by the criminal suspect, and some was transferred.

But according to Li Suigong's experience, this kind of fraudster would rather go to jail than return the money.

Jiang Yuan naturally wouldn't be demanding, also holding Li Suigong's hand, and said: "It's best to solve the case. Others, we can't control. This trip is too hard for you, three or four days, 2500 kilometers round trip, too hard."

"Nothing, mainly the driver is more tired." Li Suigong laughed.

Jiang Yuan only then knew that the Economic Investigation Brigade also hired a driver. Sure enough, it was a brigade with sufficient funds.

Wei Zhengguo glanced at Jiang Yuan, who had never seen the world, pulled him over, and said: "Captain Li, you go busy with yours, we will sit for a while and then leave."

"Okay." Li Suigong hurriedly turned back to fill out the form.

Now solving cases, all pay attention to the process. If you make a mistake, you will be filled to death.

Wei Zhengguo said to Jiang Yuan in a low voice: "Wealthy police teams like drivers, because they don't need the quota of auxiliary police, and they can help drive, take things, etc., which is very practical."

"So, the quota of auxiliary police is not enough?"

"When is the personnel quota enough?" Wei Zhengguo laughed.

Jiang Yuan also sent messages to his father and Jiang Yushan respectively.

The phone calls of the two were called over accordingly.

Jiang Yuan walked out of the office area to facilitate speaking.

He actually didn't know much, and a part of it was extremely unfriendly to the victim.

But for Jiang Yushan, hearing that the criminal suspect was brought to justice, he was very happy.

Noon.

Jiang Yuan was still hesitating whether to invite Li Suigong to dinner, or let him sleep first, and invite Dazhuang to eat another meal, when the system interface suddenly popped up:

Task completed: Find someone

Task content: A qualified forensic doctor can find people (alive/corpse) through various details.

Task reward: Footprint identification (lv3)

Jiang Yuan knew that the criminal suspect must have confessed.

With the mechanism in the country, as long as there is a confession and a certain amount of physical evidence, in the litigation stage, the defendant will at most pursue the lightness of the sentence. There is almost no escape from punishment.

Just thinking about it, Li Suigong's phone called over.

"The criminal suspect confessed, I will organize the documents later, and we will rush to prosecute, if we return the stolen money, it may be later." Li Suigong explained to Jiang Yuan.

Jiang Yuan thanked him again, and ended the call, only feeling that helping people do things is also quite hard.

Looking back, Jiang Yuan looked closely at the introduction of lv3 footprint identification.

The most significant feature of footprint identification is its extremely high extraction rate.

In almost any crime scene, footprint marks can be extracted.

In contrast, although fingerprint and DNA technologies are more mature and the identification of the same is more reliable, in terms of the current crime environment, the extraction rate of fingerprints is only less than about 15%, and the extraction rate of DNA is even lower.

When facing cases where DNA and fingerprints cannot be extracted, footprints may be the only reliance.

Jiang Yuan casually adjusted a soup with cigarette ash, stepped on it, twisted it twice, and stepped on the other side, and observed the remaining footprints.

Sure enough, countless information rushed into his brain.

Jiang Yuan got up without hesitation, went to the trace inspection office next door, opened the door, and asked: "Brother Wang, are there any footprint cases? Give me one to do?"

Footprints are also the scope of trace inspection work.

Wang Zhong was stunned by the call, and then stunned again, asking: "What does the footprint case mean?"

"I studied footprint science recently, want to find a case, and do it as homework." Jiang Yuan expressed it very humbly.

Wang Zhong was shocked!

A few months ago, Brother Jiang was also like this about fingerprints! Then he brushed and brushed and solved so many cases...

"Yes, yes, enough, you wait a moment." ===== CHAPTER 145 =====
