Chaitong is in his 40s. He looks a bit gentle and elegant, with a bit of a noble temperament.
To put it in a more layman's terms, it doesn't match the temperament of the police force at all.
However, Comrade Chai Tong had a nice smile and looked like he had been trained in a higher education institution. When he entered the office of Jiangyuan's special class for backlogged cases, he commented in a cultured way: "The name of the special class is very professional, but in fact it is not
It needs to be limited to the backlog of cases. I don’t think there are many backlogs left in Ningtai County.”
Chai Tong spoke and looked at Huang Qiangmin and others. Before he came to inspect, he had read some documents and had a certain understanding of the current situation of the Ningtai County Bureau.
Huang Qiangmin smiled and said: "We don't have many backlog cases left, mainly because Jiang Yuan has been solved."
"Jiang Yuan was responsible for all the investigations?" Chai Tong didn't quite believe this. He had also been in the political and legal system, and he also had a considerable understanding of collective power.
Huang Qiangmin laughed and said: "The backlog of murder cases last year were all solved by Jiang Yuan. Basically, all the murder cases after 2000 have been solved. Now there are only a few cases that are still being chased and have not been completely solved.
"
Chai Tong's eyes flashed: "This... is a bit amazing. How was it detected specifically?" He was indeed interested.
Among the units under a county bureau, there are as many as 20 units on par with the criminal police brigade. In addition, there are some independent lower-level units that also need the attention of the boss. For example, the Anti-Narcotics Squadron in Ningtai County,
Although the police dog squadron is relatively low in number and level, it cannot be ignored.
Therefore, after taking office, although Chai Tong spent a lot of time getting to know the Criminal Police Brigade and paid considerable attention to Jiang Yuan, it was impossible for him to look at a specific case or the detection of the case in detail.
Dossier.
At this time, I asked it as a question, and it was Chai Tong who found a topic for everyone. Otherwise, you can't just listen to your subordinates' flattery.
Jiang Yuan thought for a while and concluded: "We mainly use technology to detect cases. Commonly used technologies include fingerprint comparison, DNA comparison obtained from on-site investigation, blood stain analysis, footprint analysis, and now tool traces.
Inspections, etc......."
Chai Tong nodded "Yeah" and asked, "Do you have any specific examples to look at?"
"Oh, let's do a fingerprint then?" Jiang Yuan said, sitting at the desk and saying to Wang Chuanxing: "Connect this computer to the projector."
Jiang Yuan then skillfully opened the backend, entered the fingerprint comparison interface, found a fingerprint from the backend, and began to mark feature points. While marking, he introduced: "The fingerprint comparison we use now is to look at the fingerprint database.
Can the fingerprints inside and those at the scene be determined to be consistent?"
While talking, Jiang Yuan started to compare.
Naturally, it was not easy for Chai Tong to stand behind Jiang Yuan. Just as the big screen of the projector lit up, Chai Tong naturally put his hands behind his back, came to the front of the conference room, and sat down facing the big screen.
Huang Qiangmin stood next to Jiang Yuan and whispered: "The director may want to see the cases you have done before." Jiang Yuan was stunned for a moment: "They are all cases that have been solved...
.Then now we have to withdraw to..."
Huang Qiangmin turned around and took a look and found that Chai Tongdu was already looking at it with great interest. He could only say: "No need for now. You can operate according to your ideas."
Huang Qiangmin also had nothing to say. He had already done half of it, and it would not be a problem to withdraw. Jiang Yuan didn't seem to have any burden.
From time to time, he will also do some fingerprints for help in the fingerprint group. Occasionally, familiar fingerprint experts will send fingerprints to discuss together, and they are all temporary processing of fingerprints encountered temporarily.
For Jiang Yuan, taking out a fingerprint for comparison is no longer a burden. Moreover, after doing it more, he can actually make some judgments based on the case.
Jiang Yuan can now guess what kind of cases are easy to win, what kind of cases the criminals will be cautious about, and what kind of cases the criminals are likely to leave fingerprints on.
Like now, what Jiang Yuan pulled out was a simple theft case.
As we all know, there is a certain degree of technical content in theft. Thieves who have been doing it for a little longer are basically ex-convicts, and it is easy to leave information in the fingerprint database. And what Jiang Yuan is looking for this time is another relative.
Clear half fingerprint.
For trace examiners below LV2, it will naturally be difficult if the fingerprint area is too small.
But for Jiang Yuan, it was very simple. Once a dozen feature points were marked, the right side of the software began to produce fingerprints. "Which case is this?" Chai Tong looked at it with a little interest.
"This is a theft case in the next county. It was about two years ago. It was a shop theft case. The fingerprints were taken from the lock. There is a better chance of directly identifying the culprit." Jiang Yuan said.
, while starting to do manual comparison in the candidate list on the right.
Chai Tong said "Oh" and said: "Is there anything special about this case? I thought you would show a backlog of murder cases or something like that. Didn't you do a lot of big cases last year?"
"Director." Huang Qiangmin shouted quickly and explained: "Jiang Yuan, this guy came out with a new case." Chai Tong asked: "New case? Is it an active case?"
"No, it's an unsolved case. This fingerprint has never been matched before. Jiang Yuan will take it out and re-mark it now..." Huang Qiangmin explained.
Chai Tong couldn't help but sit up straight after hearing this, hesitated a little, and asked: "Does this mean that if the fingerprints are matched, it is possible to catch a criminal who is at large?"
"That's what I mean." Huang Qiangmin said.
Chai Tong let out a "ha" and said: "If you put it like that, well... I have inspected many units and directly demonstrated how to solve crimes. This is the first time."
After all, Chai Tong's interest suddenly piqued. This was a real live broadcast.
Although Chai Tong has been involved in the political and legal system for a while, it is relatively rare for him to see such a face-to-face and personally involved case-solving process.
Furthermore, Jiang Yuan's operation was also very smooth. Chai Tong watched the huge fingerprint expand, shrink, and move on the screen. When it felt a little repetitive, a dialog box popped up.
"Now it is almost certain that the suspect has been selected. I will submit a review now. If more than three experts pass the review, the arrest can be carried out." Jiang Yuan clicked to submit the application and introduced Chai Tong at the same time.
Chaitong was like a child visiting the zoo for the first time. He just nodded in confusion, not knowing whether the animals he encountered this time were rare species or whether the performers were working hard.
"In other words, this case has been solved?" asked a leader nearby.
"Now we have identified a criminal suspect. If he is caught, he can be interrogated. Then we will see if there are any accomplices." Jiang Yuan said roughly a few words and then said: "If nothing else happens, the case should be considered
It’s broken.”
Ding. Ding ding.
While everyone was talking, several fingerprint experts all made the same identification for Jiang Yuan's fingerprints. Jiang Yuan then looked at Huang Qiangmin and said, "It's confirmed."
"Then let's arrest people." Huang Qiangmin took out his mobile phone and called Wu Junhao from the first team. Originally, there was no need to dispatch the first squadron for this kind of case, but in order to make Jiang Yuan's exhibition match more perfect, Huang Qiangmin still decisively dispatched
Best lineup.
The new Chai Tong looked at their operations and also looked at his mobile phone and said: "So, Jiang Yuan can solve a case in twenty minutes?"
"This is good luck!" Huang Qiangmin was afraid of this and said quickly: "All resources must be coordinated."
"We should give him resources." Chai Tong couldn't help but think of his predecessor. He obviously had no hope of promotion, but it suddenly became clear.
