While Jiang Yuan was operating the mouse and comparing them one by one with the fingerprints swiped by the software, he looked up at the living room and said politely: "Well... Captain Li and Captain Liu, have some tea and have a rest. It's okay. You can check your mobile phones."
Okay. I mainly encountered some problems here, and I thought it would be better to have your local police here."
After Jiang Yuan said this, the two police officers immediately straightened their backs.
Among them, Liu Ling said: "Captain Jiang is fine. You are busy with your work. If you need anything, just say hello to us... Uh, do we have a case?"
"Yes, we happened to encounter a case, and I didn't bring anyone with me. It would be best if you could help and stay for a while." Jiang Yuan paused: "By the way, do you have guns?"
The smiles on their faces visibly solidified.
Although it is said that China is not as exaggerated as Japan, and the police department prides itself on not using guns during its career, but as far as ordinary police officers are concerned, after 2000, how many people have still held a gun while on duty? How many have fired a gun?
How many more people are there?
In county-level places like Sudao, let alone the police at the police station, the criminal police have no chance to shoot all year round.
Li and Liu originally came to give a gift and say hello to Jiang Yuan before leaving, but now...
The two of them looked at each other wildly, fearing that they would become a gift.
"If you have something to say, you can talk about it. You can play with your cell phone, but it's best not to communicate with the outside world, including your Kong Institute, and don't cause trouble for him."
What Jiang Yuan said was half true and half false. If this case is successfully completed, everyone will be happy, but if any news is leaked and someone escapes, the two people will make outgoing calls and send messages from this moment on.
All information that goes out will be censored.
The disciplinary requirements of the disciplinary forces are extremely serious when facing each other. The two police officers quickly sat up straight.
There were more than thirty fingerprints on the fan. Jiang Yuan scanned them first, then classified them, then selected some of them to mark the characteristic points, and finally classified them into seven people.
When it comes to marking feature points, a complete fingerprint is as difficult for Jiang Yuan as an oral arithmetic problem in elementary school. He can scan it with just one glance and his speed will be as fast as his hand.
This is also true in ordinary cases. Most of the fingerprints extracted are actually key fingerprints, such as fingerprints on murder weapons, fingerprints on tools, vehicle handles, window sills, door handles, etc.
Although the owner of the fingerprint is quite fancy.
Logically speaking, they could actually not listen to Jiang Yuan, but neither of them considered this choice at all.
But when we got to Jiangyuan, only half of the thirty-odd fingerprints were classified. In fact, many duplicate fingerprints had long been excluded from the thirty-odd ones.
If all the fingerprints at the crime scene were extracted, it would be endless work for most criminal teams.
Jiang Yuan only took half an hour to extract fingerprints from the entire sector, which averaged out to two minutes for each fingerprint. Jiang Yuan usually didn't need to do this.
However, the fingerprints this time are nothing fancy...
Instead, when it comes to fingerprint matching, it involves a bit of luck and metaphysics.
If it is a new person's fingerprint inspection, it may take a quarter of an hour to half an hour to make such a fingerprint and mark it. The LV1 skilled elite fingerprint inspection may be faster, but it will take about 10 minutes. The difference is that the LV1 fingerprint inspection
The accuracy is higher and the repeatability rate is higher.
In other words, just to mark the fingerprints on this sector, ordinary trace inspection may require a day or two of work. In fact, it is more than that, because there must be some difficult fingerprints that cannot be marked.
Jiang Yuan didn't say much, and turned around to continue looking for job opportunities for the colleagues who came by chartered flight.
As Jiang Yuan expected, one of the three young ladies was indeed hit, and was hit three times, making the average number of hits among the three young ladies equal to one.
This is the broken windows theory as the saying goes. Once a person has been caught once and beaten once, he is likely to be less afraid of attacking himself - this is also one of the secondary disasters that occur after drunk driving is punished.
one.
Judging from Jiang Yuan's thinking mode, the three young ladies were teased by the photographer to take a video together. Even if the business models are a little different, they are still familiar with each other.
With this in mind, Jiang Yuan picked up his cell phone again and called back to the office of the backlog class.
"Team Jiang?" Tang Jia was sitting in the center at this time.
"Well, I'll send you another person. She's a prostitute. Find out where she mainly works, and ask the local security police to find out about the situation. Well, make a call and ask her to report to the Ningtai County Bureau.
.In addition, I will give you three more people, two of whom are also suspected to be prostitutes, and one is a prostitute. You can ask technical detectives and Internet security to do some research and mark the time and place where the three of them appeared together."
As Jiang Yuan spoke, he sent several people's messages to Tang Jia.
Because Jiang Yuan's technical indicators exceeded the standard in all aspects, he always dealt with cases in a straightforward manner.
This time, Jiang Yuan is still playing straight. In his opinion, if the photographer Wang Haoyu is a drug dealer and part-time prostitute, and also runs a photo studio that is not very profitable, then even if he is a master of time management, he can use it in
The time for prostitution is also limited.
Since time is limited, there are definitely not many young ladies that Wang Haoyu can control.
And if he wants to use his job to entertain his superiors, and gather the young ladies under him to give the recipients more choices, it should be very possible.
The two people standing guard in the living room looked at each other silently. They stayed in the police station and wanted to use the technical investigation and network security on a daily basis, but they had to report in advance.
After a while, Tang Jia called back: "Now there are more than a dozen confirmed locations. Can they be sent to your mobile phone?"
"There are more than a dozen places? How many provinces and cities?" Jiang Yuan was a little surprised. This photographer has a very close relationship with the three young ladies. From this point of view, it is a bit insulting to always say that he is a prostitute.
When it comes to organizing prostitution, the difference is between 2 and 7 years in prison.
"Three provinces, five cities." Tang Jiada said.
"Well..." Jiang Yuan pondered for a moment and said: "In this case, you report it to Political Commissar Huang, and then go to the anti-drug detachment and ask them for the new drugs during this period, especially the type of drugs I sent you.
Let them compare things like the frequency of bulk shipments with the time when these people appear."
Jiang Yuan intentionally did not mention words like popping candy.
The two people in the living room were naturally even more confused after hearing this. They only knew that Jiang Yuan seemed to be preparing to mobilize the anti-drug detachment again.
At this time, the two of them were somewhat restless. After all, they really didn't have guns!
Tang Jia quickly took notes on the other end of the phone and asked: "After comparison, will the results be sent to you?"
"I want a case with clues. If a corresponding case appears at the corresponding time and place, you can send me the case number."
"clear."
Tang Jia understood at this time that Jiang Yuan connected a series of cases together in this way, which was equivalent to merging a series of drug cases through three prostitutes and prostitutes.
This method is an extremely efficient way to solve cases, but it is also quite difficult.
Of course, if the entire case can be completed in this way, it will also be a highly complete model, because the number of uncovered cases will increase, the amount of money and drugs involved will increase, and the facts involved will be more comprehensive, which will bring about the most direct consequences.
The impact is that the death penalty rate for those involved will greatly increase!
Jiang Yuan put down his cell phone, smiled at the two policemen, got up and poured a cup of tea for them, and said bluntly: "This may be a series of cases. You have worked hard to protect me this time. I will take credit for you later."
Police officer Liu Ling said subconsciously: "No, no, no..."
"What nonsense are you talking about?" The policeman next to him quickly interrupted him and said to Jiang Yuan: "Thank you, Captain Jiang. We will definitely stand guard and stay in position!"
