Chapter 143: Enough Case Management (Third Update)
Monday.
It started to rain in Ningtai County.
Abundant rainwater flows from south to north, from east to west, turning the rain outside the window into a marshy country.
Wu Jun leaned against the window sill, smoking Yuxi lonely, and said slowly: "If someone dies today, we will be in trouble."
Jiang Yuan looked up from behind the computer screen and said, "It's not that coincidental."
"Don't talk about coincidences." Wu Jun waved his hand and said: "When it comes to coincidences, it's really easy to be a coincidence. I think back then, we met a man like this..."
Wu Jun then told Jiang Yuan about ancient times.
Jiang Yuan silently looked at the training materials on the screen.
In terms of fingerprint identification, his current knowledge is also constantly improving.
However, criminal science and technology is a little different from ordinary science or technology in that it requires great external support.
Probably because the police don't pay attention to fighting alone, and no one has ever considered creating a technology that can be used by the police alone.
On the contrary, criminal science and technology often require the cooperation of partners, or even the cooperation of an entire system.
For example, with fingerprint technology, no matter how strong Jiang Yuan's identification ability is, it still relies on the fingerprint database.
The fingerprint database is actually accumulated bit by bit.
From Jiang Yuan's perspective, what currently restricts the further development of fingerprint technology is the construction of fingerprint databases and the entry and annotation of new fingerprints.
This also requires the cooperation of the entire police system.
In criminal science and technology, it is usually reflected in various trainings.
Description of the latest technology, promotion of newer technologies, use of more mature technologies...
The police system may be the unit that likes training the most in China, but even so, the grassroots strength of the police system is still weak.
The matter of entering fingerprints is not only something that can be solved by long hours of work, but also requires more detailed work arrangements and the dissemination of working methods.
At present, it seems that the system will not provide such management skills.
Jiang Yuan tried to learn by himself.
boom.
Wei Zhenguo rushed in from outside the door.
"Dead?"
Jiang Yuan and Wu Jun both turned their heads and shouted in unison.
Wei Zhenguo looked behind him cautiously, thought carefully, and then said: "No... no one died."
"Oh... I mean, it's not bad..." Wu Jun breathed a sigh of relief and stopped smoking. He quickly sat back down and touched the statue of Guan Gong without saying a word.
Jiang Yuan looked at Wei Zhenguo and said with a smile: "Captain Wei, what's the matter?"
"Oh, um, Li Suigong is back, bringing with him the criminal suspect who committed fraud." Wei Zhenguo took a breath and said with a smile, "He has been sent to the immigration center."
Jiang Yuan glanced outside unexpectedly: "At this time? Did they stay up late to catch it?"
"More than that, I have been running for three days. I also just found out that when the police were called at the checkpoint in Qi Province, Li Suigong called for people to go. The one-way trip was 1,200 kilometers and the round trip was 2,500 kilometers. In the middle, I stayed on guard for a day." Wei Zhenguo shook his head and praised: "Economic Investigation
It’s not easy to do either.”
"Then let's go take a look." Jiang Yuan quickly stood up.
When I entered the processing center, I saw Li Suigong and another police officer filling out forms. The colleague next to me was already sprawled out on the sofa.
There weren't many people running the center, but there were always people coming and going, and Li Suigong just didn't see them.
"Captain Li." Jiang Yuan greeted quickly.
"Brother Jiang." Li Suigong quickly held Jiang Yuan's hand. He went to Qi Province because of Jiang Yuan. Now that he is back, of course he wants to sell it well.
"Don't be so polite. I heard you arrested someone and brought him back?"
Li Suigong nodded heavily, and then said with some embarrassment: "We followed the person's line, but unexpectedly, this guy had already transferred the money. The final recovered funds may be less than 300,000.
"
He actually knew that it was impossible to completely recover the money. Moreover, although 800,000 pairs were a lot for ordinary people, various funding channels did not serve ordinary people. Therefore, Li Suigong ignored the whereabouts of the money from the beginning.
After I caught the person, I asked and looked again, and sure enough, there was only a little over 200,000 left.
Part of the remaining money was squandered by the suspect, and part of it was probably transferred.
But based on Li Suigong's experience, most of these fraudsters would rather go to jail than pay back the money.
Of course, Jiang Yuan would not seek perfection and blame, but he also held Li Suigong's hand and said: "It would be best if we can break the eucalyptus. The rest is not something we can control. You have worked too hard on this trip. In three or four days,
A round trip of 2,500 kilometers is too hard.”
"It's okay, it's mainly because the driver is tired." Li Suigong laughed.
Only then did Jiang Yuan know that the Economic Investigation Brigade also hired a driver. It was indeed a brigade with sufficient funds.
Wei Zhenguo took a look at Jiang Yuan, who looked like he had never seen the world, pulled him closer, and said: "Captain Li, you go about your business first, and we'll leave after we sit back."
"Okay." Li Suigong quickly turned around and filled out the form.
Nowadays, everyone pays attention to the process when breaking the bank. If you make a mistake, you will have to fill in the form until you die.
Wei Zhenguo whispered to Jiang Yuan: "Nowadays, rich police forces like drivers, because they don't need the auxiliary police quota, and they can help drive, pick up things, etc., which is very practical."
"So, there are not enough auxiliary police places?"
"There are never enough personnel quotas." Wei Zhenguo chuckled.
Jiang Yuan also sent messages to his father and Jiang Yushan respectively.
The phone calls from the two of them came immediately.
Jiang Yuan walked out of the office area to speak more easily.
In fact, he doesn't know much, and some of them are extremely unfriendly to the victims.
But for Jiang Yushan, he was very happy to hear that the suspect was brought to justice.
noon.
Jiang Yuan was still hesitating whether to treat Li Suigong to a meal or to let him sleep first and treat Da Zhuang to another meal. The system interface suddenly popped up:
Mission accomplished: Find someone
Mission content: A qualified forensic doctor who can find people (living/corpse) through various details.
Mission reward: Footprint identification (LV3)
Jiang Yuan knew immediately that the suspect must have confessed.
According to the domestic mechanism, as long as there is a confession and certain physical evidence, the defendant can only pursue the severity of the sentence during the litigation stage. Almost no one can escape punishment.
Just as I was thinking this, Li Suigong called.
"The suspect has given up. Let's go back and sort out the documents. We will seize the time to prosecute. If we want to return the stolen goods, we may have to wait a little longer." Li Suigong explained to Jiang Yuan.
Jiang Yuan thanked him again and ended the call. He felt that it was quite hard to help others.
Looking back, Jiang Yuan carefully read the introduction of LV3's footprint identification.
The most significant feature of footprint identification is its extremely high extraction rate.
Footprints can be extracted from almost any crime scene.
In comparison, although fingerprint and DNA technologies are more mature and identification of identity is more reliable, in the current criminal environment, the extraction rate of fingerprints is only about 15%, and the extraction rate of DNA is even lower.
When faced with cases where DNA and fingerprints cannot be extracted, footprints may be the only reliance.
Jiang Yuan casually mixed some soup with cigarette ashes, stepped on it, twisted it twice, stepped on the other side, and observed the footprints left behind.
Sure enough, countless information rushed into my mind.
Jiang Yuan got up without hesitation, went to the trace inspection office next door, opened the door, and asked: "Brother Wang, do you have any traces of the traces? Can you do it for me?"
Footprints are also the scope of work for trace inspection.
Wang Zhong was confused when he was called, and then he was confused again, and asked: "What does the eucalyptus on the footprints mean?"
"I recently studied footprint science and wanted to find a way to do it as an after-school homework." Jiang Yuan expressed humbly.
Wang Zhong couldn't help but feel shocked!
A few months ago, Brother Jiang said the same thing about fingerprints! Then he broke so many fingerprints...
