Bai Shengsheng's fingerprints looked neat and tidy, like a little girl coming out of a boudoir.
However, Jiang Yuan knew that this decent fingerprint was returned to the lake a few hours ago like an African-American comedian. It was because of all the hard work he had spent on it using a computer borrowed from the Provincial Detective Corps.
It took a long time and the LV4 level image enhancement skills were used to restore it to its current appearance. It can be called an epic plastic surgery, equivalent to transforming an orange cat into a ragdoll cat.
And if you want to count the people behind it, Bai Shengsheng's fingerprints will also turn black and red.
Jiang Yuan did a routine marking of feature points and stopped after scanning 300 fingerprints and finding no hits.
This fingerprint is quite special.
It was taken from the collar behind the neck of the deceased. Based on the technology of a few years ago, to do this, the on-site investigation technicians had to have pretty good skills.
However, the technician who made the discovery still failed to match this fingerprint.
Jiang Yuan stared at this fingerprint that looked like it had undergone plastic surgery and fell into deep thought.
He could imagine that when the murderer, the owner of this fingerprint, tried to strangle the deceased beneath him, the strength of his fingers would be stretched to the limit. Correspondingly, the deceased must have tried his best at the last moment,
He tightened his muscles and tightened his skin to resist the murderer's attack.
Therefore, this is a fingerprint that is deformed in both directions on a soft material. Now that the marked feature points cannot be found, the normal next step should be to adjust the deformation. According to the lines and structure, make some artificial adjustments. Basically, just rely on
Try to find a match.
Some fingerprints can be completed in a few months in the hands of a fingerprint examiner. There are also fingerprint examiners who hold a few large eucalyptus fingerprints and keep trying, and some may take several years.
Jiang Yuan had also used the test method before to compare fingerprints. That was because he had enough relevant information and conditions to conduct the test.
However, Jiang Yuan looked at this fingerprint over and over again, but he didn't feel that there was any room for adjustment.
It’s not that it can’t be adjusted, but because both the applied force and the received force are deformed, it is much more difficult to try out. Moreover, its current mark inspection technician is obviously an expert, and Jiang Yuan can think of all the solutions.
, the other party has probably tried it too.
But without using conventional solutions, which direction should we go to achieve surprise?
The total is about one square centimeter of fingerprints. It is not easy to play with it over and over again for months and years, and still think of another surprise and a trick that no one has thought of before.
Fingerprints of fate are difficult to deal with.
During Jiang Yuan's contemplation stage, the system's translucent interface silently jumped in front of Jiang Yuan.
…
Mission: persistent pursuit
Mission content: During the fingerprint battle, try your best to detect as many cases as possible. Current progress (8*2)
…
Judging from the content, 8*2 should be the total number of pieces and the number of pieces of life.
Jiang Yuan's thoughts were interrupted for a moment, and he turned around to think again. He glanced at the fingerprints from the corner of his eyes and couldn't help but think: Actually, there is no need to consider the entire fingerprint.
This fingerprint was taken from the neck, and the curvature of the neck, which may not be noticeable at ordinary times, is likely to show up when someone is about to be strangled to death.
Jiang Yuan simply cut out a small piece of the fingerprint and marked it.
It is equivalent to saying that most of the fingerprints that people have worked so hard to remove have been abandoned.
Just the most stable piece.
Such a small piece of fingerprint was carefully extracted with characteristic points, and then scanned in the software. The resulting fingerprint made Jiang Yuan feel like he saw hope.
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. One obvious difference is that the Qingdao-style single-finger fingerprint analysis method divides fingerprints into 68 subcategories, while the Chongqing type is 24.
A subcategory.
This difference makes the Chongqing style better to buy, while the Qingdao style is more suitable for manual brushing.
A few seconds for one fingerprint, or hundreds of fingerprints, all passed quickly.
After 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 what he was doing to look at Jiang Yuan's operations.
He kind of wants to steal from me.
Jiang Yuan had no intention of blocking it.
Fingerprint comparison is a very personal task, especially the processing of difficult fingerprints. After achieving this step, judgment is more important than skill.
Skills can be learned, but judgment involves many things.
Li Zemin was still thinking about Jiang Yuan's thoughts. At this time, he saw that Jiang Yuan moved the mouse and actually chose "identify as the same".
"You won the competition?" Li Zemin was surprised.
He knew that Jiang Yuan was comparing his fate.
Jiang Yuan took a sip of tea, moistened his throat, and then said, "Then see if you win."
"That's right." Li Zemin then turned back to look at his screen, and heard the sound of "ding dong" one after another in his ears.
It's a beautiful time in the morning, and many people have their notifications turned on for new messages.
Now that I saw it, many people clicked it to take a look.
Jiang Yuan's name is like a cup of refreshing coffee poured on everyone's heads.
Comfortable.
Eye-catching.
Full of energy.
Li Zemin looked at the fingerprint image carefully several times, and then slowly clicked Agree under "Confirm Identical".
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? Is he fast because his technology is really strong and he is already a provincial powerhouse? Or is it that image processing technology should be combined with fingerprint technology, and his image enhancement skills,
Is it also at the level of a weak provincial strong person?
"Smoke a cigarette?" Jiang Yuan took out a pack of soft Chinese.
"Let's go." As expected, Li Zemin changed the subject, 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 blankly.
The expressions of the others were better, but they were also quite surprised to get the smoke.
Li Zemin was not too used to the behavior of people from the provincial department. Looking at this scene, he couldn't help but smile. "People from Qinghe?" The middle-aged man who put away his cigarette confirmed.
"Yes, from Jiangcun, Ningtai County." Jiang Yuandan lit the fire calmly and smoked a cigarette in front of several smokers.
Seeing that Soft China was spat out as worthless, several people showed unbearable expressions, but considering their status as Jiangcun people, they were too lazy to complain.
"Jiang Yuan!" A policeman with his collar button fastened stepped out from the provincial building with great seriousness.
Jiang Yuan and others recognized him when they got closer, and said with a smile: "Liu Chu."
The one 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 read the police alert. Did you hit the fingerprint on Wu Long Savage's collar?"
From Liu Jinghui's description, you can tell that he paid a lot of attention to this case. Not only did he set up relevant reminders, he also had a clear understanding of the victim's condition.
Jiang Yuan said without hesitation: "There was a murder. The deceased was found in Wulong Mountain."
"That's it, that's it..." Liu Jinghui clicked his fingers twice, his emotions rising visibly.
However, his colleagues from the provincial department looked at Jiang Yuan curiously and said in surprise: "You won a life in the competition? Are you here to participate in the fingerprint battle?"
"Yes. People from Qinghe." Jiang Yuan replied using the noun he had just been asked about.
Everyone understood. The middle-aged man who was the first to speak up just now laughed and said: "He is quite temperamental, but again, how can Jiangcun people 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 more like a fatal accident." The person next to him pointed out his thumb and made a sign.
Li Zemin helped: "Three."
"Three what?"
"I won three lives in the competition." Li Zemin raised three fingers.
Everyone was amazed.
The middle-aged man took a sip of the newly lit Zhonghua and said with a smile on his face: "You really can't see Mount Tai. Let me meet you. My name is Hong Wanjun. Brothers call me Hong Qi, Hong Qigong's Hong, Hong
Qi Gong's "qi" refers to my temper. At best it sounds like I hate evil, but at worst it means I always offend people..."
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 puzzled.
"Go and investigate Wu Long Savage. This trap is definitely not a simple dumping of corpses in the wild." Liu Jinghui said firmly, "I think there is something hidden in this trap, 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 description of the situation.
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 for traveling together..."
"Now that we've 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 6 years after serving his sentence. There has been no news for six years, and he participated in a murder in the middle. This kind of person
, it is difficult to find it directly. However, Wu Long Savage has finally opened up a new direction of investigation. I now invite you to join me in forming a new special team..."
"Liu Chu, I'm participating in the fingerprint battle." Jiang Yuan interrupted Liu Jinghui. He didn't like Liu Jinghui. In his opinion, reasoning is neither mysterious nor reliable. Liu Jinghui reasons first and then
The pattern of evidence was even less agreeable to him. Under such circumstances, Jiang Yuan was naturally not willing to form any special team with Liu Jinghui.
But Liu Jinghui looked at Jiang Yuan with affection in his eyes and said word by word: "I'll wait for you!"
