Chapter 91 I'll Wait for You

The white fingerprint image looks very proper, like a girl who has just walked out of the boudoir. Google search reading

Jiang Yuan knew that this fingerprint, which looked like a real one, was still blurry like an African-American comedian a few hours ago. He had to work hard to restore it to its current appearance with a computer borrowed from the Provincial Department of Image Detection Corps. It took a long time and LV4-level image enhancement skills. It can be called an epic plastic surgery, equivalent to changing an orange cat into a ragdoll cat.

And to count the people behind it, the white fingerprint image must also become black and red.

Jiang Yuan did a routine feature point marking, scanned 300 fingerprints, and stopped when he didn't match.

This fingerprint is quite special.

It was taken from the collar behind the neck of the deceased. With the technology a few years ago, the technicians who conducted the on-site investigation had to have quite good skills to do this.

However, the technicians who worked on the case at the time still failed to match this fingerprint.

Jiang Yuan stared at the fingerprint that looked like it had been reshaped, and fell into deep thought.

He could imagine that when the murderer, the owner of this fingerprint, tried to strangle the deceased under him, the strength of his fingers would be used to the limit. Correspondingly, the deceased must have tried his best at the last moment, tightened his muscles and skin to resist the murderer's attack.

So, this is a fingerprint that has been deformed in two directions on a soft material. Now the marked feature points cannot be made, so the next step should be to adjust the deformation. According to the lines and structure, some artificial adjustments are made. Basically, it is to rely on trial to find a match.

Some fingerprints can be done in a trace inspector for several months, and some trace inspectors hold fingerprints of several major cases and keep trying, and some try for several years.

Jiang Yuan had previously used the trial method to compare fingerprints, because he had enough relevant information and conditions to test.

However, Jiang Yuan looked at this fingerprint over and over again, and he didn't think there was room for adjustment.

It's not that it can't be adjusted, but because both the force applied and the force received are deformed, the difficulty of trying it out has greatly increased. Moreover, its current case trace inspection technician is obviously an expert. The solutions that Jiang Yuan can think of are probably tried by the other party.

But if the conventional solution is not used, which direction can be used to surprise and win?

In total, it is only about one square centimeter of fingerprints. People have been playing with it over and over for several months and years. It is not easy to think of another surprise and another trick that no one has thought of before.

Fingerprints in murder cases are difficult to deal with.

While Jiang Yuan was thinking, the semi-transparent interface of the system silently jumped in front of Jiang Yuan.

…

Task: Persistent pursuit

Task content: During the fingerprint battle, do your best to solve multiple cases. The current progress is (8*2)

…

Judging from the content, 8*2 should be the total number of cases and the number of murder cases.

Jiang Yuan's thoughts were interrupted for a moment, and then he turned around to think. He glanced at the fingerprint and couldn't help thinking: In fact, there is no need to consider the entire fingerprint.

This fingerprint was taken from the neck, and the curvature of the neck may not be obvious at ordinary times, but when it is about to be strangled, it is likely to be reflected.

Jiang Yuan simply cut a small piece from the fingerprint and marked it out.

In other words, most of the fingerprints that people took with great effort during the on-site investigation were abandoned.

Only the most stable small piece was needed.

Such a small piece of fingerprint was carefully selected for feature points, put into the software for scanning, and the fingerprints that were output made Jiang Yuan feel hopeful.

He now uses the Qingdao-style single-finger fingerprint analysis method to process this small piece of fingerprint.

The Qingdao-style single-finger fingerprint analysis method and the Chongqing-style single-finger fingerprint analysis method have their own advantages and disadvantages and differences. A more obvious difference is that the Qingdao-style single-finger fingerprint analysis method divides fingerprints into 68 subcategories, while the Chongqing-style is 24 subcategories.

This difference makes the Chongqing style easier to start with, while the Qingdao style is more suitable for manual swiping.

One fingerprint every few seconds, hundreds of fingerprints were quickly swiped.

As he swiped, Jiang Yuan sat up straight, stared at a fingerprint, and compared it carefully.

Li Zemin next to him noticed it, and stopped his work to watch Jiang Yuan's operation.

He wanted to learn from him.

But Jiang Yuan didn't want to cover it.

Fingerprint matching is a very personal job, especially the handling of difficult fingerprints. After this step, judgment requires more skills.

Skills can be learned, but judgment involves more things.

Li Zemin was still thinking about Jiang Yuan's thinking. At this time, he saw Jiang Yuan move the mouse and actually chose "identify the same".

"Is it right now?" Li Zemin was surprised.

He knew that Jiang Yuan was comparing murders.

Jiang Yuan drank a sip of tea, moistened his throat, and then said, "Then see if you match it."

"That's right." Li Zemin turned back to look at his screen, and heard the sound of "ding dong" one after another.

The morning time is beautiful, and many people have new message notifications turned on.

Seeing it now, many people clicked to see it.

Jiang Yuan's name is like a cup of cool coffee poured on everyone's head.

Comfortable.

Eye-catching.

Energetic.

Li Zemin carefully looked at the fingerprint image several times, and then slowly clicked "Agree" under "Confirmed to be the same".

Turning around, Li Zemin looked at Jiang Yuan in great surprise and asked, "So fast? Is image processing so useful?"

Jiang Yuan smiled, how could he answer, saying that he was fast because his skills were really strong and he was already a provincial powerhouse? Or should we say that image processing technology should be combined with fingerprint technology, and that my image enhancement skills are at the level of a weak provincial-level expert?

"Smoke a cigarette?" Jiang Yuan took out a pack of soft Chinese.

"Let's go." As expected, the topic was changed. Li Zemin immediately stood up and followed Jiang Yuan away.

In front of the building.

In the antique pavilion, several smokers from the provincial government were smoking nicotine. When they saw Jiang Yuan and Li Zemin coming over, they smiled friendly.

Jiang Yuan also nodded, and Li Zemin and a Chinese team occupied the other side of the pavilion.

One of the smokers in the provincial department saw the soft Chinese in Jiang Yuan's hand and immediately frowned. Regardless of the eyes of his colleagues next to him, he directly said in a dissatisfied tone: "The conditions are so good? These days, the people in the units below are What are you thinking about? One by one..."

"I'm from Jiangcun." Jiang Yuan didn't let the other party finish his sentence, and handed over a Chinese stick in a very Jiangcun social manner.

The middle-aged man who spoke still maintained a serious frown and took the cigarette in a daze.

The expressions of others were better, but they were also quite surprised to get loose smoke.

Li Zemin was not too used to the behavior of the people in the provincial department. Looking at this scene, he couldn't help but smile.

"From Qinghe?" The middle-aged man who had collected his cigarette confirmed.

"Yes, from Jiangcun, Ningtai County." Jiang Yuan calmly lit the fire and smoked a cigarette in front of several smokers.

Watching soft China being spat out worthless. Several people showed unbearable expressions, but considering that they were from Jiangcun, they were too lazy to complain.

"Jiang Yuan!" A policeman with his collar button fastened stepped out of the provincial building with great seriousness.

Jiang Yuan and others recognized him when they got closer, and said with a smile: "Liu Chu."

The person who came quickly was none other than Liu Jinghui, a fourth-level provincial senior police sergeant who was known for his reasoning.

He walked into the pavilion, looked at the middle-aged men who were puffing away, reluctantly nodded, and said hello: "Hong Chu."

Turning around, Liu Jinghui asked, "I just saw the police alert. Did you hit the fingerprint on Wu Longsavage's collar?"

From Liu Jinghui's description, you can tell that he is extremely concerned about this case. Not only are relevant reminders set, but the victim's condition is also clearly understood.

Jiang Yuan said without hesitation: "We found a murder case. The deceased was found in Wulong Mountain."

"That's it, that's it..." Liu Jinghui clicked his fingers twice, his emotions rising visibly.

His colleagues from the provincial department looked at Jiang Yuan curiously and said in surprise: "You won a murder case? Are you here to participate in the fingerprint battle?"

"Yes. People from Qinghe." Jiang Yuan replied using the term he was just asked about.

Everyone understood. The middle-aged man who was the first to speak up laughed and said, "You are quite temperamental, but again, how can people in Jiangcun have no temper? I'm sorry just now, I thought you were seconded to live here. "Young man, I didn't expect you to come here for a fingerprint battle. It's rare to see such a young fingerprint expert."

"It's a murder case." The person next to him pointed out his thumb and gestured.

Li Zemin helped: "Three."

"Three what?"

"Three murders were won in the competition." Li Zemin raised three fingers.

Everyone clicked their tongues in amazement.

The middle-aged man took a sip of the newly lit Zhonghua and said with a smile on his face: "You are really blind to the sight of Mount Tai. Let me meet you, my name is Hong Wanjun. Brothers all call me Hong Qi, Hong Qi Gong's Hong, Hong Qi Gong's "Qi" means that my temper is, at best, jealous of evil, but at worst, I offend people everywhere..."

Jiang Yuan shook hands with him and exchanged WeChat IDs.

Liu Jinghui, who was next to him, was also full of emotions at this time. Taking advantage of a gap, he said: "Jiang Yuan, you have to follow me."

"Where to go?" Jiang Yuan was confused.

"Investigate the Wu Long Savage Case. This case is definitely not a simple case of dumping corpses in the wild." Liu Jinghui said firmly, "I think there is something hidden in this case, and it is probably a series of murders..."

"There are still corpses?" Jiang Yuan was surprised and thought, he didn't see it in the case description.

Liu Jinghui said seriously: "There is no corpse. It is possible that other corpses could be dumped in a better place. But judging from the handling of this corpse, the person who killed the corpse and dumped it has rich experience. Moreover, this corpse's There is also a certain degree of coincidence in the discovery. It was discovered by a lost traveler. It is not on the road patrolled by mountain rangers, and there are no conditions nearby to travel with it..."

"Then now that we have won the competition, shouldn't we arrest people first?"

"It's been too long." Liu Jinghui shook his head slightly and said, "You should be able to see for yourself that the suspect in Bizhong has been released for six years after serving his sentence. There has been no news in six years, and he was involved in a murder case. This kind of person , it is difficult to find it directly. However, the Wu Long Savage case has finally opened up a new direction of investigation. I now invite you to join me in forming a new task force..."

"Liu Chu, I'm participating in the fingerprint battle." Jiang Yuan interrupted Liu Jinghui. He didn't like Liu Jinghui. In his opinion, reasoning was neither mysterious nor reliable. Liu Jinghui's model of reasoning first and then providing evidence was not even approved by him. Under such circumstances, Jiang Yuan was naturally not willing to set up a special task force with Liu Jinghui.

Liu Jinghui looked at Jiang Yuan with affection in his eyes and said word by word: "I'll wait for you!"
