"Team Huang... do you remember the last time we met?" Wan Baoming walked a little further, holding the mobile phone in his hand, his head hanging lower than his shoulders, and his waist hanging down.
It's not easy being a deputy director, and there aren't many things he can offer, but Huang Qiangmin has a pretty big appetite.
There was clearly a trace of sparkle in Wan Baoming's eyes.
It's not easy to do something.
Jiang Yuan couldn't see Comrade Wan Baoming's eyes and expression. He was sitting on the other side of his study room, almost 20 meters away from Wan Baoming's chosen corner. He couldn't even hear Wan Baoming's words clearly.
Of course, Jiang Yuan had no interest in listening to him argue with Huang Qiangmin.
He turned on the computer himself, put in the fingerprints that Wanbaoming had brought, and processed them briefly with Photoshop first.
Having been doing fingerprints for a long time, Jiang Yuan has been able to make some judgments of his own before matching with the software. Whether he can match the fingerprints and how close the matched fingerprints are are all predictable.
Generally speaking, if fingerprints that are too incomplete are not processed by image software first, it is possible to match any kind of ghost or snake.
Of course, it is possible to match the correct fingerprint, but for technical people, playing this kind of probability game is meaningless. Those LV2 level trace inspectors may only use this method to cover ultra-difficult fingerprints.
task, but for Jiang Yuan, he has transcended this level.
He needs to be at least LV4.2 now, and even the 0.2 behind him is going to be a big win.
I have done a lot of difficult fingerprints and always succeeded. This experience is valuable in itself. Just like an ordinary person who has been in the position of president for a long time, he can gradually figure out a little bit of experience.
.
The fingerprints that Wan Baoming brought over this time were a bit too incomplete. Based on Jiang Yuan's experience, if they are now thrown into the fingerprint software for matching, the answers obtained are equivalent to randomness.
This is not surprising. If the difficulty had not exceeded the level of LV3, why would Wanbaoming be so humble?
After Wan Baoming and Huang Qiangmin talked for a few minutes, Wan Baoming came over with his mobile phone and whispered: "Jiang Yuan, your team Huang's phone number."
"Okay." Jiang Yuan took the call.
"Jiang Yuan, how was your rest? Are you tired?" Huang Qiangmin asked with a smile on the phone.
"It's not bad. I've been building the wall all day and I'm a little sweaty," Jiang Yuandao said.
"It's good to sweat. I feel good after sweating." Huang Qiangmin laughed and said: "Wan Baoming gave you another fingerprint? Follow the stick. Is the fingerprint he took this time difficult?
"
"High. The probability of making it directly is not high." Jiang Yuandao.
"Oh, can you win in the competition? Can you win in the competition?"
"Then it depends on whether there are fingerprints in Curry." Jiang Yuan paused and said: "Even if there are fingerprints in Curry, it still depends on the quality of Curry's fingerprints..."
"If you give me a number, how sure are you that it can be done?"
"Six." Jiang Yuan looked at Wan Baoming and didn't hide it too much.
Based on keyword analysis alone, Jiang Yuan felt that Wanbaoming must have sought help from fingerprint experts from ministries and commissions.
But to be honest, fingerprint experts in ministries and commissions may not necessarily have LV4 level. There are powerful experts who must be above LV4 level, and maybe there are also LV5 bosses.
But experts also want to talk about probability and investment.
Can Wanbaoming hire a fingerprint expert who is strong enough and require him to devote himself to it?
It's probably very difficult.
The greater possibility is that the other party tried to help, failed to compete within a short period of time, and then gave up.
After all, experts from ministries and commissions are very busy. There are more than 30 provinces in the country like Shannan Province. Even experts may not be able to produce one extremely difficult fingerprint in a week.
This is just like during the fingerprint battle. Normal experts at the Shannan Provincial Department level will look at about 100,000 fingerprints during the whole battle for 15 days. It would be good if they can compare with a few.
The intensity and importance of battles are completely different from daily help.
Jiang Yuan only said to Huang Qiangmin: "There is little hope that this fingerprint can be done normally in the province."
Huang Qiangmin understood and said cheerfully: "Okay, then you give the phone to Wan Baoming, and I will ask him to pay for the last fingerprint."
Jiang Yuan smiled: "It only took more than two hours to put on the fingerprints."
"Others have told me this, it depends on the computing power." Huang Qiangmin said confidently: "Give your phone to Wan Baoming, don't feel bad for him, there are many rich places in Changyang City, you can leak a little bit between your fingers.
, enough for our small county to struggle for 10 years."
Jiang Yuan laughed and returned the phone to Wan Baoming.
Wanbao Mingzhen took it over with great importance, put it solemnly in his ear, and said: "Captain Huang, my little Wan..."
Wan Baoming continued walking to the corner while talking.
Jiang Yuan sat back in front of the computer. Before the host started roaring, Jiang Yuan could vaguely hear some mysterious keywords:
"please."
"It's really sad."
"Yellow Team~"
"Please give me a hand..."
…
After a long time, Wan Baoming sent the phone with a hot back cover to Jiang Yuan.
Jiang Yuan: "Hey, Team Huang."
Huang Qiangmin: "Let's take a look at it. I'll ask them to send two people over to give us training. In addition, let's borrow some of their old equipment and so on. I still have the opening. You can see it later.
Just tell me what you want and what you want."
Jiang Yuan said a little embarrassedly: "Okay."
"Okay, turn on the speakerphone." Huang Qiangmin said.
Jiang Yuan then took off his cell phone and turned on the speaker phone.
Huang Qiangmin's voice came out: "Jiang Yuan, you have to do your job well with Director Wan's side. You still have two days of vacation, so don't take it now. Count on going to work again. Once you finish it, you are here
Xiu. Changyang City Criminal Division Center has helped us with many cases before. You should cherish the opportunity to cooperate this time..."
"Yes." Jiang Yuan responded calmly.
"Director Wan, I'll leave Jiang Yuan to you. Young people are immature and if they don't do well, please bear with me. If you have any questions, just come to me directly and I'll criticize him..." Huang Qiangmin chattered.
He ended the call nagging.
Wan Baoming put away his cell phone and sighed: "You, Team Yellow, are not as easy to talk to as before."
Jiang Yuan just smiled and said nothing.
Borrowing someone else's big green cow to plow the land is probably not the same as borrowing a cat to catch mice.
When the mouse moves, the computer starts to buzz.
In terms of image rendering, no matter how high the configuration of the computer, the sound is the same. This is just like that, right?
"Director Wan, can you please introduce the case?" Jiang Yuan took this time to ask Wan Baoming.
"This is a case at the Maixin Electronics Factory last year. A female worker was pushed down on the roof of the building. At first, she thought she was committing suicide. Later, an eyewitness said that she saw two people on the roof of the building.
The pushing action..." Wan Baoming described the scene, and then focused on the evidence:
"The early dispatch of the police was actually a bit problematic, because at first I thought it was a suicide, so the on-site protection was not very good. The factory security guards and workers all ran to the roof of the building."
"Secondly, there are only eyewitnesses and lack of surveillance video. Because they are all wearing work clothes, it is not easy to judge the murderer."
"The third thing is that the workers in the factory are not very familiar with each other. This Maixin factory adopts a hiring and hiring model. It means signing a large OEM order and recruiting a group of workers to do it.
Once it’s almost done, we’ll fire it and wait until there’s a big order next time before hiring people. Therefore, it’s not easy to solve the case through social connections.”
Jiang Yuan listened to Wan Baoming's introduction and couldn't help but ask: "Then the only evidence is the fingerprints on the clothes?"
Wan Baoming sighed: "The problem now is that the fingerprints on the clothes have become evidence in the opposite direction. Several suspects that the criminal police focused on questioning have been eliminated by the fingerprint evidence on the clothes..."
Jiang Yuan couldn't help but smile when he heard this, and asked again: "Then everyone in the factory should have their fingerprints taken?"
"Yes. When something went wrong, the factory was immediately closed, and all entrances and exits were under video surveillance."
Jiang Yuan couldn't help but nodded. In this way, the problem of the fingerprint database was actually solved.
From the perspective of a fingerprint examiner, this is a perfect environment for fingerprint comparison. You only need to make fingerprints and you can do the comparison.
Thinking of this, Jiang Yuan frowned again and said: "The core problem is to match fingerprints. We really couldn't match last year's case. Matching one person at a time can always be done..."
Wan Baoming couldn't help but smile, and quickly covered it up, saying: "I just said that the factory belongs to Maixin. You may not know much about it. At that time, this factory took a big order and was in a full workload. There are workers in the factory area.
Nearly 30,000 people.”
Jiang Yuan suddenly realized.
For a large factory with tens of thousands of people, it is definitely unrealistic to compare fingerprints one by one, especially when the fingerprints are in such poor condition.
"What did you use to extract fingerprints? 502?" Jiang Yuan looked at the fingerprints and gradually entered the state of fingerprint comparison.
Wan Baoming understood Jiang Yuan's hidden meaning and smiled bitterly: "Yes, 502 Xunxian."
Similar to ninhydrin fumigation, the 502 glue fumigation method is also a method of revealing latent sweat fingerprints after applying chemical reagents.
Similarly, all similar solutions actually have a layer of problems that people rarely talk about, and they are prone to defects in operation.
Criminals leave fingerprints accidentally, but if the fingerprints are damaged and incompletely displayed, they will definitely not give another copy.
Just like the fingerprints in front of me, they are so damaged that the fingerprint inspection has to be difficult to match. Usually, you have to complain a few words about the fingerprint extraction. Usually the ones who get scolded are also the spotters.
Jiang Yuan used image software to slightly adjust the fingerprints and gradually came up with an idea.
Feeling energetic, he was too lazy to talk to Wan Baoming and said, "If you don't play like a dog, I'll tell you the results once the results are achieved."
"Okay." Wan Baoming responded before he finally came to his senses: "Should I wait here?"
"Then... if you have something to do, go and do it first." Jiang Yuan naturally didn't care.
Wan Baoming said hurriedly: "That's not what I meant, I meant... uh, will the results be available today?"
"It's possible. The main thing now is to process the image. This fingerprint was taken from cotton clothes. Cotton, a natural fiber, is spirally twisted. The cross section of the fiber is like a waist, and it is easy to get lint. This is caused by sweat.
The main reason why fingerprints are not expressive enough..." Jiang Yuan explained to Wanbao Minglue.
Wan Baoming looked at Jiang Yuan and said: "I have also done a trace inspection, and I understand the truth, but..."
Jiang Yuan was silent for a moment, and then said: "If you are bored, why don't you go back to Changyang City and send the people and things that Team Huang wants to him? Send them to him and come back. I almost have them here.
It worked."
He has now processed nearly half of the images, and the clarity of the images he consciously processed is acceptable. Considering that Changyang City has collected the fingerprints of everyone in the factory, it means that the comparison library is complete, and the possibility of matching is very low.
Greatly increased.
In fact, if the fingerprint cannot be matched in this case, the matter itself will be very meaningful and valuable.
Therefore, the answer given by Jiang Yuan is very certain.
Wan Baoming felt that Jiang Yuan was a bit crazy, but looking at Jiang Yuan's expression, he didn't notice the madness.
"Okay. I'll go back first and report to the leader. I'll come back and wait for your good news." Wan Baoming calmed down all his emotions.
His philosophy is that as long as you can make something, I will obey you.
With this thinking model, Wan Baoming's abilities were average, but he was recognized by many criminal investigation experts and became the deputy director of the Changyang Criminal Investigation Center.
Within the Criminal Division Center, Wan Baoming is also a relatively recognized leader. This is also because he is a type of person who respects technology more.
As long as Jiang Yuan can make things, Wan Baoming can accept the combination of Jiang Yuan and Huang Qiangmin.
But if it doesn't work, then Wan Baoming will have to talk to Huang Qiangmin and Jiang Yuan.
After leaving the house and getting in the car, Wan Baoming even started talking to the group in advance:
Daily depression: [I took last year’s backlog of murder cases and found Jiang Yuan’s super difficult fingerprints. Unexpectedly, Jiang Yuan answered immediately and went to move bricks to change fingerprints...]
South Expedition Bei Zhan: [I’ve only heard of moving bricks for 30 days and going to the club on the 31st. What the hell is moving bricks to change fingerprints?]
Daily depression: [Team Huang has made some conditions, and I have to prepare some resources for him. You can’t let people work for nothing. No, what the hell are you carrying bricks to the club?"
Fighting in the south and in the north: [Moving bricks is so tiring, if it wasn’t for going to the club, it would be a tearjerker.]
Daily depression: [What to do if there is no number 31?]
Fighting in the south and in the north: [You are moving bricks, not robbing banks. It will take two months to save enough money? 】
Daily depression: [It makes sense...]
Fighting in the south and in the north: [What conditions did the yellow team set? Do you still have to prepare resources?]
Daily depression: [A few technicians, a few pieces of equipment, and the technicians brought an on-site survey vehicle over.]
Fighting in the south and in the north: [So good? Is there a new car to use?
The daily sluggish man who was scrolling through his cell phone in the car couldn't help but sit up, frowning and typing:
Daily sluggishness: [No, who are you @南尊北War]
Fighting in the South and North: [I... am just a man who has traveled extensively, accumulated some experience and is willing to share it. 】
Ningtai County Criminal Police Brigade.
Sitting in the office, Liu Wenkai, who was bored, let out a long breath, raised his head again, and said to the squadron instructor: "Let's also find two backlogged cases and start a tough battle."
"You are looking for fault? Are you done with the case in hand?" the instructor sneered.
Liu Wenkai chuckled and said in a low voice: "I have received rumors that our team will probably have a few new temporary workers, some of whom are technical."
"So good?" The instructor was surprised: "We have no establishment for a long time, where did we get the people to cheat?"
"The criminal police team from Changyang City came here for support, probably."
"Reverse secondment?"
"I guess. Do you want it?" Liu Wenkai said calmly: "If you want people, don't you have to have a project?"
"Okay, okay, open the backlog, open the backlog." The instructor said twice. For a squadron that is busy every day, there is nothing more comfortable than adding more manpower.
