Chapter 260 Please

"Captain Huang... Do you remember the last time we met?" Wan Baoming walked a little further, holding the phone in his hand, his head was lower than his shoulders, and his waist was down.

It is not easy for the deputy director, and there are not many things that can be sold, but Huang Qiangmin has a big appetite.

Wan Baoming's eyes clearly contained traces of crystal clearness.

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 choice corner, and he couldn't even hear Wan Baoming's words clearly.

Of course, Jiang Yuan wasn't interested in listening to him argue with Huang Qiangmin.

He turned on the computer by himself, put the fingerprints brought by Wanbaoming into it, and first processed it with Photoshop.

After doing fingerprints for a long time, Jiang Yuan was able to make some judgments of his own before matching with the software.Whether it can be compared, and how similar the fingerprints are in the comparison, these are all predictable.

Generally speaking, if a fingerprint with a high degree of incompleteness is not processed with image software first, it is possible to match any ghosts and monsters.

Of course, it is also possible to match the correct fingerprint, but as a technical person, it is not interesting to play this kind of probability game. Those LV2 level trace inspectors may only use this method to cover when doing ultra-difficult fingerprints. task, but for Jiang Yuan, he has already surpassed this gear.

He must be at least at the level of LV4.2 now, and the latter 0.2 will have to beat a lot of people.

I have done a lot of difficult fingerprints, and I always succeed. This kind of experience itself is commendable.It's like an ordinary person who has been in the position of president for a long time and can gradually figure out a little bit of experience.

The fingerprints brought by Wanbaoming this time are a bit too incomplete. Based on Jiang Yuan's experience, if they are thrown into the fingerprint software for matching, the answers they get are equivalent to random.

This is not surprising, if it wasn't for the difficulty exceeding the LV3 level, why would Wanbaoming be so humble.

After Wan Baoming talked with Huang Qiangmin for a few minutes, Wan Baoming came over with his mobile phone and said in a low voice, "Jiang Yuan, your yellow team's number."

"Okay." Jiang Yuan answered the phone.

"Jiang Yuan, how is your rest? Are you tired?" Huang Qiangmin asked with a smile on the phone.

"It's okay. I've been building a wall for a whole day today, and I'm sweating a little," Jiang Yuan said.

"Sweating is good, sweating, and the body is comfortable." Huang Qiangmin laughed, and said again: "Wan Baoming gave you another fingerprint? Hit a snake with a stick. Is the fingerprint he took this time difficult? "

"High. The probability of making it directly is not high." Jiang Yuan said.

"Oh, can you win the match? Can you give it the match?"

"That depends on whether Curry has fingerprints." Jiang Yuan paused, and said, "Even if Curry has fingerprints, it depends on the quality of Curry's fingerprints..."

"If you give a number, how sure are you that you can make it?"

"Six." Jiang Yuan looked at Wan Baoming, and he didn't hide it too much.

From the analysis of keywords alone, Jiang Yuan felt that Wan Baoming must have asked the fingerprint experts of the ministries and commissions for help.

But to be honest, the fingerprint experts of the ministries and commissions may not have the level of LV4.There are powerful experts, there must be those who are above LV4 level, maybe there are also LV5 bosses.

But experts also talk about probability and investment.

Can Wanbaoming invite a fingerprint expert who is strong enough and ask the other party to devote himself wholeheartedly?

It is estimated that it will be difficult.

It is more likely that the other party helped to take a look, and gave up after failing to compare in a short period of time.

After all, the experts of the ministries and commissions are very busy. There are more than 30 provinces like Shannan Province in the country, and even experts can't make one of the ultra-difficult and difficult fingerprints in a week.

It's like during the fingerprint battle, experts who normally belong to the Shannan Provincial Department level, the whole battle lasted for 15 days, and they looked at about 10 fingerprints, and it would be good if they could compare a few of them.

The intensity and importance of battles are completely different from daily help.

Jiang Yuan only said to Huang Qiangmin: "This fingerprint will be done normally in the province, there is little hope."

Huang Qiangmin understood it, and said cheerfully: "Okay, then you hand over your mobile phone to Wanbaoming, and I will ask him to make up for the cost of the last fingerprint."

Jiang Yuan smiled: "The last fingerprint took more than two hours."

"Others have told me about this, and it has to be calculated according to computing power." Huang Qiangmin said confidently, "Give Wan Baoming your mobile phone, don't feel sorry for him, what a rich place Changyang City is, there is a little leakage between your fingers , Enough for our small county town to struggle for 10 years."

Jiang Yuan laughed, and returned the phone to Wan Baoming.

Wanbao Mingzhen took it over, solemnly put it in his ear, and said: "Captain Huang, I am little Wan..."

While talking, Wan Baoming continued to walk into the corner.

Jiang Yuan sat back in front of the computer, before the host started to roar, Jiang Yuan could vaguely hear some very mysterious keywords:

"please."

"It's really sad."

"Yellow Team~"

"Help me..."

……

After a long time, Wan Baoming sent the mobile phone with a hot back to Jiang Yuan.

Jiang Yuan: "Hello, Captain Huang."

Huang Qiangmin: "Let's take a look at it. On my side, let them send two people over to give us training. In addition, let's borrow some old equipment from them. I still have the hole. Look back. Whatever you want, whatever you want, just tell me.”

Jiang Yuan said with a little embarrassment: "Okay."

"Okay, you turn on the speakerphone." Huang Qiangmin said.

Jiang Yuan then took down the phone and turned on the speakerphone.

Huang Qiangmin's voice came out: "Jiang Yuan, you should work hard on the tasks on Director Wan's side. You still have two days of vacation on your side, so don't take it off and count it back to work. When you finish it later, you are here Hugh. Changyang City Criminal Center has helped us with many cases before, this time you have the opportunity to cooperate, you should cherish it..."

"Yes." Jiang Yuan responded politely.

"Director Wan, I will leave Jiang Yuan to you. Young people are ignorant. If there is anything wrong with it, please take care of it. If you have any problems, just come to me and I will criticize him..." Huang Qiangmin chattered Nagging ended the call.

Wan Baoming put away his mobile phone and sighed: "You team yellow, you are not as talkative as before."

Jiang Yuan just smiled and said nothing.

Borrowing other people's big green cattle to plow the land is probably different from borrowing a cat to catch mice.

Move the mouse, and the computer beeps.

In terms of image rendering, no matter how high the configuration of the computer is, the sound is the same. This is like that, right?

"Director Wan, is it convenient to introduce the case?" Jiang Yuan took this time to ask Wan Baoming.

"This is the case of Maixin Electronics Factory last year. A female worker was on the roof and was pushed down. At first, she thought it was suicide. Later, witnesses said that they saw two people on the roof, and there were Pushing and shoving..." Wan Baoming described the scene, and then emphasized the evidence:

"The police dispatch in the early stage was actually a bit problematic, because I thought it was a suicide at first, so the protection on the scene was not very good. The security guards and workers of the factory all ran to the roof of the building."

"Secondly, there are only witnesses and there is no surveillance video. Because they are all wearing work clothes, it is not easy to judge the murderer."

"The third is that the workers in the factory are not very familiar with each other. This Maixin factory is based on the mode of employing and recruiting people. It is to sign a large OEM order and recruit a group of workers to do it. It’s almost done, so let’s fire it and wait until the next time there is a big order before recruiting. Therefore, it is not easy to solve the case along the lines of social relations.”

Listening to Wan Baoming's introduction, Jiang Yuan couldn't help asking: "The only evidence is the fingerprints on the clothes?"

Wan Baoming sighed: "The problem now is that the fingerprints on the clothes have become reverse evidence. Several suspects that the criminal police focused on questioning were all ruled out by the fingerprints on the clothes..."

Jiang Yuan couldn't help laughing, and then asked: "Then everyone in the factory should have their fingerprints taken?"

"It was picked. When something happened, the factory was immediately closed, and the video surveillance of the import and export was also complete."

Jiang Yuan couldn't help but nodded. In this way, the problem of the fingerprint database was actually solved.

From the point of view of a trace inspector, this is a very perfect environment for fingerprint comparison, as long as you make fingerprints, you can do comparison.

Thinking of this, Jiang Yuan frowned again, and said: "The core problem is matching fingerprints. Last year's case really couldn't be matched. Matching one by one can always work..."

Wan Baoming couldn't help smiling, and quickly covered it up, saying: "I said just now that the factory belongs to Maixin. You may not understand it well. At that time, the factory received a big order and was in a state of full workload. There are workers in the factory area. Nearly 3 people."

Only then did Jiang Yuan suddenly realize.

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 the fingerprints? 502?" Jiang Yuan looked at the fingerprints and gradually entered the state of fingerprint comparison.

Wan Baoming understood Jiang Yuan's implied meaning, and smiled wryly: "Yes, 502 Xunxian."

Similar to ninhydrin fumigation, the 502 glue fumigation method is also a solution to reveal latent sweat fingerprints after applying chemical reagents.

Similarly, all similar solutions actually have a layer of problems that people seldom talk about, and they are prone to flaws in operation.

Criminals left fingerprints by accident. If the fingerprints are damaged and the display is incomplete, they will definitely not give another copy.

Just like the fingerprint in front of me, it was so crippled that the trace inspection had to be matched bitterly.Usually have to complain about two sentences to extract fingerprints.Usually the ones who get scolded are the spot surveyors.

Jiang Yuan used image software to slightly adjust the fingerprints, and gradually got an idea.

When he regained his energy, he didn't bother to talk about Wan Baoming, and said: "If you want to play with dogs, I'll tell you when there is a result."

"Okay." Wan Baoming responded, before he came to his senses: "Shall I wait here?"

"Then...you can go to work first if you have something to do." Jiang Yuan naturally didn't care.

Wan Baoming hurriedly said: "That's not what I mean, I mean...uh, can there be a result today?"

"It's possible. Now the main thing is to process images. This fingerprint is taken from cotton clothes. Cotton, a natural fiber, is twisted in a spiral. The cross-section of the fiber is like a waist, and it is easy to fluff. The main reason for the lack of expressiveness of fingerprints..." Jiang Yuan briefly explained to Wan Baoming.

Wan Baoming looked at Jiang Yuan, and said, "I've also done a trace inspection, and I understand the truth, but..."

Jiang Yuan was silent for a while, and then said: "If you are bored, why don't you go back to Changyang City and send him the people and things that the Yellow Team wants? After sending them to him, I will almost have them here. It worked out."

He has already processed nearly half of the images, and the clarity of the processed images consciously is acceptable. Considering that Changyang City has already collected the fingerprints of everyone in the factory, it means that the database for comparison is complete, and the possibility of the comparison is just greatly increased.

In fact, if in this case, the fingerprints cannot be compared, the matter itself will be very meaningful and valuable.

Therefore, Jiang Yuan's answer is very positive.

Wan Baoming felt that Jiang Yuan was a bit crazy, but seeing Jiang Yuan's expression, he didn't know that kind of madness.

"Okay. I'll go back first and report to the leader. I'll come back and wait for your good news." Wan Baoming restrained all his petty emotions.

His idea is that as long as you can make something, I will obey you.

With this way of thinking, Wan Baoming's abilities were mediocre, but he was recognized by many criminal investigation experts, and he became the deputy director of the Changyang Criminal Investigation Center.

Within the criminal center, Wan Baoming is also a relatively recognized leader.It is also because he is a type of person who respects technology.

As long as Jiang Yuan can make something, Wan Baoming can also accept the combination of Jiang Yuan and Huang Qiangmin.

But if it doesn't work, then Wan Baoming will talk to Huang Qiangmin and Jiang Yuan in reverse.

After leaving the house and getting in the car, Wan Baoming said in advance in the group:

Daily depression: [I found Jiang Yuan with last year's homicide case.Super difficult fingerprints, I didn't expect Jiang Yuan to answer in one gulp, now go to move bricks to change fingerprints...]

Southern Expedition and Northern War: [I only heard that bricks were moved for 30 days and went to the clubhouse on the 31st. What the hell is moving bricks for fingerprints? 】

Daily sluggishness: [The yellow team has set some conditions, I have to prepare some resources for him.You can't make people work for nothing.No, what the hell are you moving bricks to the clubhouse? "

Southern Expedition Northern War: [Moving bricks is so tiring, if it's not for going to the club, it's a tear gas film. 】

Daily depression: [What if there is no number 31? 】

Southern Expedition Northern War: [You are going to move bricks, not rob a bank, it will take two months to save enough money? 】

Daily depression: [It makes sense...]

Southern Expedition and Northern War: [What conditions did the yellow team offer?You still have to prepare resources? 】

Daily depression: [A few technicians, a few pieces of equipment, the technicians brought a field survey vehicle over. 】

Southern Expedition Northern War: [So good?Got a new car?
Daily sluggishness, who was swiping his phone in the car, couldn't help sitting up, frowning and typing:
Daily sluggishness: [No, who are you @南盾北战]

Conquering the North and the South: [I... am just a man who has traveled all over the world, 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, then raised his head, and said to the squadron instructor: "Let's also find two backlogged cases and start a tough battle."

"Looking for guilt? Are you done with the case in hand?" the instructor snorted.

Liu Wenkai chuckled, and said in a low voice, "I have received gossip that our brigade will probably have a few new temporary workers, who are still engaged in technology."

"So good?" The instructor was very surprised: "We have no way to prepare, where did you get someone?"

"The criminal police team from Changyang City came to support them. Probably."

"Reverse secondment?"

"Probably. Do you want it?" Liu Wenkai said calmly, "If you want someone, you have to have a project?"

"Let's go, let's open the accumulated case, open the accumulated case." The instructor said it twice.For a squadron that is busy on all fours every day, there is nothing more comfortable than adding manpower.
