National Forensic Doctor

After a dinner party where the ceremony was more important than the content, fingerprint experts from all over the country left the venue one after another and returned to their dormitories. Some even went home directly. Google search reading

Experts who solved the murder case, as well as experts such as Zhu Huanguang who ranked first in matching fingerprints, were specially kept to take photos and interviews.

Some people may be rewarded for their meritorious service, but for now, no one is really talking about this topic.

Jiang Yuan is still eagerly studying the blood stain analysis of LV5.

Bloodstain analysis is useful, but LV5 is more irritating.

Thinking about Da Zhuang's passion for dog food, you can almost imagine how the blood spray will be connected to the murderer.

"Expert Jiang, please come over here." Another reporter appeared, grabbed Jiang Yuan, and took photos.

Then, the reporter asked a series of questions that reporters had asked before, and asked Jiang Yuan to dress up in various borrowed police uniforms and take a series of photos.

Li Zemin took the opportunity to hold Jiang Yuan and took many photos.

"Hey, you're going back now. This fingerprint battle ended so quickly." Li Zemin held a Chinese cigarette in his mouth, patted Jiang Yuan's shoulder with worry on his face, and made a backhand V to the reporter in front.

Behind the two of them was the enlarged and printed ranking list from the fingerprint post.

On the left is the "Ranking of Backlog of Homicide Cases". Jiang Yuan ranks first with 10 results; Li Zemin ranks 35th with 0 results.

On the right is the "ranking list of backlogged cases solved". Jiang Yuan ranks first with 18 results.

; Li Zemin ranked 35th, with 0 results.

Both of them looked very happy and took many more photos in front of the ranking list. Li Zemin said that he wanted to take it back to show to his brothers that he came out to participate in the fingerprint battle this time and fought with the number one fingerprint expert.

As for his own ranking and number of results, it doesn't matter.

Jiang Yuan was also quite emotional and slapped Li Zemin with his backhand. The 14 days of the fingerprint battle were a very simple and happy 14 days. He would do fingerprints and occasionally go out for fun and chat. At night, he would have a solid sleep and not think about how many more murderers would be there because of himself. And die.

The black and white of the world appeared in front of Jiang Yuan with rare clarity and was affected by him.

During this period of time, Jiang Yuan no longer had to worry about boys half his life suddenly rushing out on the street and grabbing his arm to play with him while studying every day like he did in school. There is no need to wander around boringly with boring second- and third-generation people like at home, or be caught by strange people promoting strange investment projects.

Li Zemin is also a good companion. He is not obsessed with fingerprints like Jiang Yuan. He is almost always available and can follow him just after opening a pack of cigarettes. He has a relatively easy-going personality and is a rare young person among a group of experts. type.

"Come to Liyuan City when you have time. We are close to Pingzhou, with mountains and grasslands. The meat is really delicious..." Li Zemin warmly invited Jiang Yuan and said goodbye reluctantly.

He had no results, so naturally there was no such thing as interviews and awards for meritorious service. On the other hand, it is quite refreshing to be away from home for half a month, but when I go back, I still miss my family and friends. The clothes on my body also stink, I'm tired of the food in Changyang City, and the cigarettes I bring when I go out...it's time to find a place to hide them.

Jiang Yuan bid farewell to Li Zemin, pretending to be tough, and stuffed him with two packs of "Zhonghua". Then he looked at the online car-hailing car going away, and suddenly felt a little sad. The excitement during the fingerprint battle gave people a completely different feeling from the celebratory bustle of people coming and going at this time.

"Jiang Yuan. Congratulations."

Just when Jiang Yuan was a little disappointed, Liu Jinghui appeared behind him.

"Liu Chu?" Jiang Yuan was a little surprised.

To put it bluntly, Jiang Yuan didn't like Liu Jinghui.

In particular, his approach of using evidence without trusting it is rare in today's police circles.

However, at this moment, seeing Liu Jinghui, an acquaintance like him, made Jiang Yuan feel extremely comfortable, even a little bit right.

"I'll give you a gift." Liu Jinghui smiled and handed Jiang Yuan a bag and said, "Congratulations on your ranking first. This time, you must be at least second-class."

He pointed to the "Homicide Backlog Ranking" at the back and said: "In previous years' fingerprint battles, if the participating experts could win four or five murders, they would be considered second-class. You are amazing this time, with 10 murders, I can see that several leaders are grinning from ear to ear. The criminal police teams in various places are also very lively. Based on the number of people, there must be thousands of people staying up late."

"Have everyone been arrested?" Jiang Yuan couldn't help but ask.

"Absolutely. Unless you have other cases on your back, you can basically find the rightful owner." Liu Jinghui said as if he was very familiar with such cases: "The main characteristics of old cases are that they are difficult to solve. There is no need to worry about arresting them. . Time has passed and the case has not been solved. Many murderers have lived a normal life of daily necessities. As far as I can see, the more serious the suspects in such major cases, the more they like this kind of trivial ordinary life. .When the arresters arrived, their anger... was as if their dream life had collapsed, and few resisted..."

Liu Jinghui took a deep breath with enjoyment and said with a cruel smile: "I like to see them crying the most."

Jiang Yuan was fascinated when he heard it, and felt that he might also like to watch it.

After a while, Jiang Yuan realized the bag he was holding, quickly picked it up and asked, "You also gave me a gift. What gift was it?"

"A light-blocking eye mask will make you more comfortable when sleeping. Being careful is not disrespectful." Liu Jinghui smiled sincerely.

Jiang Yuan took it apart and saw that it was indeed a light-blocking eye mask. It didn't look like it was very expensive. He hesitated for a moment and accepted it.

And there was something strange in his heart. He couldn't rest well in the dormitory here. Every time he thought about getting a blindfold, he forgot about it when he was working, and thought about it again when he was sleeping...

As a result, he actually gave it away thoughtfully?

After all, he is a fourth-level senior police sergeant from the provincial department, and they have sent it over. To say the matter itself, it is more valuable than a blindfold.

"What are your plans next?" Liu Jinghui asked.

"It depends on the superiors' arrangements," Jiang Yuandao said.

"In that case, you will probably take photos for a few more days, and then publish them in newspapers for a few days, and then attend various conferences, participate in awards, and maybe go to some units to give speeches. The most troublesome thing is that you are likely to be sent Participate in some super complex cases." Liu Jinghui saw Jiang Yuan's calm expression, so he continued: "When I say complicated, I don't mean the complexity of the case, but probably the complexity of the distribution of benefits."

Jiang Yuan was stunned and asked, "What case?"

"You should ask, why you?" Liu Jinghui gave Jiang Yuan a moment to think, and then said: "We agreed on the Wu Long Savage Case, remember? You said you would wait until the fingerprint battle is over, and now the fingerprint battle It’s over too…”

"Liu Chu, I didn't agree." Jiang Yuan laughed and shook his head. Although murder cases are quite high-end, there must be many murder cases in Ningtai County, and there is no need to follow the unpopular Liu Jinghui around.

Liu Jinghui took a deep look at Jiang Yuan and seemed to have guessed his thoughts. He said calmly: "The Wu Long Savage Case is somewhat famous in our province, and it is much more interesting than the murder case in Ningtai County. Moreover, How many resources can the county bureau have? In the end, you won’t be able to run away from any of the meetings you are supposed to hold, and you don’t know where you will be seconded..."

Jiang Yuan had to admit that Liu Jinghui was not only good at reasoning, but also a bit good at persuading people.

"Okay, I'm going to make preparations. I'll help you with your county bureau. Let's go to Wulong Mountain and come back. Calculate the time and give you a medal or something. It'll be comfortable." Liu Jinghui finished. , turned around and left.

…

After a comfortable night's sleep wearing a blindfold, Jiang Yuan saw Liu Jinghui and a Great Wall Cannon at the door of the dormitory early the next morning.

The blue Great Wall Cannon was wrapped in a cargo box. The paint was dirty, the leather was worn, and the tires were old. It looked like it had weathered the weather for a long time.

Jiang Yuan called his master Wu Jun last night and decided to follow Liu Jinghui to Wu Longshan. But looking at the tragic appearance of this Great Wall Cannon, I have doubts about his so-called abundant resources.

"The hall is like this. If there are some that are useful, I won't give you a replacement for a new one." Liu Jinghui motioned Jiang Yuan to get in the car and drove off.

"Is it just the two of us?" Jiang Yuan asked helplessly.

Liu Jinghui looked forward and said, "If you find something, call someone. If you can't find it, it won't be too embarrassing, right?"

Jiang Yuan...I believe you.

…

Just as Jiang Yuan followed Liu Jinghui to Wulong Mountain, criminal police from many places and even experts from outside the province came to Changyang City.

Fingerprint paste is not unique to Shannan Province. A fingerprint battle solved 10 murders in 14 days, which shocked the police community and attracted many experts to follow suit.

But for well-known reasons, fingerprint experts are usually not very familiar with image enhancement techniques, such as Fourier transformations of different categories, such as Fourier transform of non-periodic continuous signals, Fourier series of periodic continuous signals, and discrete time of non-periodic discrete signals. I am not very proficient in domain Fourier transform, discrete Fourier transform of periodic discrete signals, etc.

Therefore, after trying for a few days, everyone rushed to Changyang City to try to find Jiang Yuan to learn from.

Most experts think that Jiang Yuan may have mastered a relatively simple technology that can make some changes to blurred fingerprints relatively easily.

The thoughts of the criminal policemen and criminal police leaders who rushed here were more direct. It would be great to ask Jiang Yuan to compare a few fingerprints or help process the fingerprints.

But no one expected that the fingerprint battle had just ended. Where was Jiang Yuanren? Where are people?
