Chapter 92 I'm Waiting For You

Bai Shengsheng's fingerprints showed a well-behaved appearance, like a little girl who walked out of a deep boudoir.

But Jiang Yuan knew that this decent fingerprint, a few hours ago, was still blurred like an African-American comedian. It took a long time to restore it to its current appearance with LV4 image enhancement skills, which can be called an epic plastic surgery, which is equivalent to turning the orange cat into a puppet cat.

And to count the people behind it, Bai Shengsheng's fingerprints will also turn black and red.

Jiang Yuan made a routine feature point marking, and stopped after scanning 300 fingerprints.

This fingerprint is quite special.

It was taken from the collar on the back of the neck of the deceased. With the technology of a few years ago, to do this, the technicians on the scene survey had to have quite good skills to do it.

However, the technician who worked on the current case still failed to match this fingerprint.

Jiang Yuan stared at this fingerprint that seemed to have undergone plastic surgery, and fell into deep thought.

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

Therefore, this is a fingerprint deformed in two directions on a soft material. Now the marked feature points cannot be made, so the next step is to adjust the deformation normally.According to the line and structure, make some artificial adjustments, basically, it is to find a match by trial and error.

Some fingerprints, in the hands of a trace inspection, can be done for several months, and some trace inspections hold the fingerprints of several major cases, and keep trying for several years.

Jiang Yuan had also used the method of trial before to pass the fingerprint comparison, which meant that he had enough relevant information and conditions to do the test.

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

It's not that it can't be adjusted, but because both the applied force and the received force are deformed, the difficulty of trying it out is greatly increased.Moreover, its on-the-spot trace inspection technician is obviously a master, and the other party has probably tried all the solutions that Jiang Yuan can think of.

But without a conventional plan, which direction should we go to surprise and win?
A total of about one square centimeter of fingerprints, after being played over and over for several months and years, and still wanting to make a surprise, and think of a trick that no one has ever thought of before, it is not easy.

The fingerprints of the murder case are difficult to deal with.

During Jiang Yuan's contemplation stage, the translucent interface of the system silently jumped in front of Jiang Yuan.

……

Mission: persistent pursuit
Task content: During the fingerprint battle, try to solve as many cases as possible, the current progress (8*2)

……

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

Jiang Yuan's thoughts were interrupted for a moment, and then he turned around to think, glanced at the fingerprints from the corner of his eyes, and couldn't help thinking: Actually, 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 it may be reflected when it is about to be strangled to death.

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

It is equivalent to giving up most of the fingerprints that people have worked so hard to remove.

As long as the most stable piece.

Such a small piece of fingerprint was carefully taken out of the feature points, put into the software to scan, and the fingerprints discharged made Jiang Yuan feel hopeful.

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

The Qingdao-style single-fingerprint analysis method and the Chongqing-style single-fingerprint analysis method have their own advantages and disadvantages and differences. One obvious difference is the Qingdao-style single-fingerprint analysis method, which divides fingerprints into 68 sub-categories, and the Chongqing-style single-fingerprint analysis method is 24. subclass.

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

One fingerprint in a few seconds, hundreds of fingerprints, quickly swiped over.

Brushing and brushing, 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 kind of wanted to steal the teacher.

Jiang Yuan had no intention of covering it up.

Fingerprint comparison is a very personal job, especially the handling of difficult fingerprints. After this step, judgment is more important than skill.

Skills can be learned, but there are many things involved in judgment.

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

"Is this the match?" Li Zemin was surprised.

He knew that Jiang Yuan was comparing murder.

Jiang Yuan took a sip of tea, moistened his throat, and said, "Then see if Bizhong is there."

"That's right." Li Zemin turned his head to look at his screen, and there were "ding dong" sounds in his ears one after another.

The morning is beautiful, and many people have notifications for new messages turned on.

Now that I saw it, many people clicked to take a look.

Jiang Yuan's name is like pouring a cup of cool coffee on everyone's heads.

Comfortable.

striking.

Vigorous.

Li Zemin carefully looked at the fingerprint image several times, and then slowly nodded his approval under "Confirm the same".

Turning his head, Li Zemin looked at Jiang Yuan in surprise, and asked, "So fast? How useful is image processing?"

Jiang Yuan smiled, how could he answer, saying that he was already a provincial strongman because of his really strong technology?Or is it that the image processing technology needs to be combined with the fingerprint technology, and that his own image enhancement skills are also at the level of the weak provincial strong?

"Smoking a cigarette?" Jiang Yuan took out a pack of soft China.

"Let's go." Sure enough, the subject was changed, Li Zemin immediately got up and followed Jiang Yuan.

in front of the building.

In the antique small 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 Li Zemin occupied the other side of the small pavilion.

Among the smokers in the provincial department, one of the smokers saw the soft Zhonghua in Jiang Yuan's hand, and immediately frowned. Regardless of the eyes of the colleagues next to him, he said in a dissatisfied tone: "The conditions are so good? These days, the following units 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 Zhonghua in a very Jiangcun society.

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

The expressions of the others were a little better, but they also got scattered smoke quite unexpectedly.

Li Zemin wasn't too used to the behavior of the people from the provincial department, so he couldn't help but smile when he saw this scene.

"People from Qinghe?" The middle-aged man who collected the cigarettes confirmed it.

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

Watching Ruan Zhonghua being spat out worthlessly.Several of them showed unbearable expressions, but thinking about their identity as Jiangcun people, they didn't bother to complain.

"Jiang Yuan!" A policeman with his collar buttoned up stepped out of the provincial building very seriously.

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

The one who came quickly was Liu Jinghui, the fourth-level senior police chief of the provincial department, who was known for his reasoning.

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

Turning his head, Liu Jinghui asked: "I just saw the police alert, did you match the fingerprints on Wu Long's collar?"

From Liu Jinghui's description, one could tell that he paid a lot of attention to this case.Not only has the relevant reminder been set, but also has a clear understanding of the victim's condition.

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

"That's it, that's it..." Liu Jinghui tapped his fingers twice, and his emotions became visible to the naked eye.

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

"Yes. People from Qinghe." Jiang Yuan used the noun he was asked just now to return to the past.

Everyone understood. The middle-aged man who was the first to speak just now laughed and said, "He has a temper, but it's true. How can people in Jiangcun have no temper. I'm sorry just now, I thought you were seconded to hang out. You're so young, I didn't expect you to come here to do the fingerprint competition, such a young fingerprint expert is rare."

"It's even a murder case." The person next to him deliberately extended his thumb and gestured.

Li Zemin chimed in, "Three."

"Three what?"

"Three murder cases have been selected." Li Zemin raised three fingers.

Everyone was amazed.

The middle-aged man took a sip of the newly ignited Zhonghua, and said with a smile on his face: "This is really blind to Mount Tai. Get to know me, my name is Hong Wanjun. Brothers call me Hong Qi, Hong Qigong's Hong, Hong Qi Gong’s Qi. It refers to my temper, which sounds like a hatred for evil, and hurts people everywhere..."

Jiang Yuan shook hands with him and exchanged WeChat IDs.

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

"Where are you going?" Jiang Yuan was puzzled.

"To 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 else hidden in this case, it may be a serial murder case..."

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

Liu Jinghui said seriously: "There is no corpse, it may be that other corpses are thrown in a better place. But judging from the treatment of this corpse, the person who killed and dumped the corpse has rich experience, and the corpse of this corpse There is also a certain coincidence in the discovery, it was discovered by a lost travel friend, it is not on the road patrolled by the mountain rangers, and there are no conditions for walking nearby..."

"Then now that you've won the competition, shouldn't you 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 for six years, and he was involved in a murder case. This kind of person , It is very difficult to find it directly. However, the Wu Long Savage case has opened up a new direction of investigation, and now I 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 doesn't like Liu Jinghui. In his opinion, reasoning is neither mysterious nor reliable.Liu Jinghui's mode of reasoning first and then evidence is not recognized by him.Under such circumstances, Jiang Yuan was naturally unwilling to form a task force with Liu Jinghui.

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