At about 10 o'clock in the evening, the "801" backlog investigation section was still brightly lit.

The leader said that you don't need to work overtime, you can't really not work overtime.

Deputy Director Xia was sitting in the command center while studying several backlogged cases to be investigated by the Second Section next week, while waiting for Section Chief Wang and them to send the guns back to the warehouse. A few colleagues who didn't go home on the weekend were either making up for their English or uploading information and photos of the nameless corpses sent by several city bureaus in the afternoon.

Tai Chao was really embarrassed to go back to the dormitory alone, looked sideways at the dark window for a while, relaxed his eyes, and continued to "hang out" the fingerprint database of ex-offenders, and continued to look for needles in a haystack.

I thought that I could do a big job after the New Year, but I didn't expect to be transferred from the second department to the fourth department as soon as I went to work, which made him very depressed and depressed.

It's not that I don't like the job of comparing fingerprints, but I lose the opportunity to detect. Participating in the secondment examination of the "801" organization is that I don't want to be a "tool" anymore, and I always "assist in detection" like before.

After a big turn, he became a technical police officer again, why is his life so bitter, thinking about it and sighing again.

Liu Huafeng, who had just caught a needle in the haystack a few years ago and had just made a great achievement, felt very funny, put down the mouse and said with a smile: "Brother Chao, don't be like this, our four subjects are not as bad as you think." If you don't believe me, I'll convert it for you, last year, the province's homicide detection rate was 99%, which is equivalent to the second section cracking a backlog of cases, which is equivalent to the city bureau and county bureau cracking 99 homicide cases.

The second section can't be solved and handed over to the third section, and now it's just begun, and the backlog of cases is not easy to count, but I feel that it's about 10%. In other words, the cracking of one backlog case by the third department is equivalent to the cracking of 10 cases by the second department. It's even more remarkable to come to us, or it won't break. Breaking together is equivalent to breaking 1,000 cases in the city and county bureaus, how meaningful this work is! ”

Tai Chao was made ridiculous. Sideways said: "Lao Liu, how can you count like this." And even if we find a clue, it's help. The second and third departments investigated, and the operations department arrested, but nothing happened to the four sections. ”

"Who said that?"

Liu Huafeng's face was straight: "Brother Chao, I'm not joking with you." Section Chief Qi said that the cases of the four departments will be investigated by themselves, and what will be done by the second and third departments will be done by the four sections, and there will be nothing to do with us. ”

"Technicians can lead the detection?"

"What are you lying to do, Section Chief Qi is from a technical background like you, can you watch you, a technical policeman, suffer? As long as you have a clue. As long as you are sure of one or two, you can go to Director Xia and get the car keys to check now. Commander, like the 'Little Witch' and Zhan Shengrong, it's up to you to decide. ”

Tai Chao was suspicious: "Lao Liu, don't be funny, the last time you found out the identity of the victim, didn't you have anything to do?" ”

"Last time, it was a special situation, one is to solve the case within a time limit, and the other is the current murder case. Two different things from what we're doing now. If you don't believe it, wait and see if our case will be interfered with by others, and at most we will command the Operations Division to help us arrest us. ”

"If that's the case, it's so-so, and the point is that our case here is basically no different from an unsolved case. It's easier said than done to find clues. ”

"So our work is challenging, breaking 1,000 of them."

There are two cases in the four sections, and the nameless corpse is too difficult to investigate. Tai Chao decided to use his expertise to work on this fingerprint. Let's see if we can also put a satellite like Liu Huafeng.

A small fingerprint is usually only one square centimeter. Even if it is enlarged on the computer, it is only about the size of a palm, but the dense and dense lines that are entangled are full of mysteries.

The buckets, kei, points, eyes, grooves, bows, and loops on the top...... It's confusing and ever-changing. It can be said that every fingerprint extracted from the crime scene is a labyrinth that hides countless secrets, and at the end of the maze are criminals.

It has been "fishing" for half a month since I went to work after the holiday, and I can't find a few similar ones every time, is it possible that the murderer has no criminal record and no samples in the fingerprint database?

He lit a cigarette, stared at the LCD monitor and analyzed the characteristics of his fingerprints again, using the "temperament" partition of the automatic fingerprint identification system that he had figured out before being seconded to "801".

The result was disappointing, only one "jumped" out, just similar, not the same person. If one move doesn't work, then change another move, and compare the regions, the result is just as frustrating, there are only two.

This is so abnormal that under normal circumstances you should be able to search for nearly 10 fingerprints in the vast database.

He was puzzled, and was about to get up to go to the bathroom, only to hear Li Zhongchen complaining behind his back: "What kind of digital camera is used here, the photos are so blurry and accidentally sent to us, I can't see anything clearly, what's the difference between uploading it on the Internet and not transmitting it?" ”

Liu Huafeng smiled without looking back: "It may have been taken at night, and the light is not good." Call tomorrow and ask if the body is cremated, and if it is not cremated, let them take another picture. ”

"That's all there is to it."

The speaker has no intention, but the listener has the intention.

The conversation between the two made Tai Chao's eyes light up, and he secretly thought that the fingerprint collected by the Dongzhou Municipal Bureau 28 years ago may be too clear, and the fingerprint conditions in the sample bank are not good, so it can't be compared.

"I know, I know what to fish! Lao Li, if I can really get the suspect out, I will invite you to dinner. ”

He threw away the cigarette box, immediately threw himself in front of the computer, quickly adjusted his thinking, re-marked the fingerprint's dots, hooks, bow lines, circular lines and other features, blurred the fingerprint features by unconventional means, and then compared them with the fingerprint database.

This adaptation made 10 pieces out at once.

That's right, the grassroots police station and the criminal police team let the suspect dip his finger in ink when collecting, and the fingerprint lines are shallow, intermittent, and have few useful features, so that the system cannot automatically compare them with the clear fingerprints collected at the scene.

He carefully compares them one by one with the naked eye according to the characteristics that have been deeply seared into his brain these days.

However, human fingers are flesh and blood, even if it is the same person, different forces when committing the crime, different force surfaces, and different fingerprints left at the scene, deformation is very common.

The samples in the fingerprint database were collected and entered under different circumstances, and some were mutilated, distorted, and blurred. As a result, even if 10 fingerprints of 10 suspects are collected, there are corresponding 10 fingerprints in the fingerprint database, but the system may not be able to automatically compare them all.

The 10 fingerprints that the system just gave are similar, but only similar.

has been working at the grassroots level for so many years, and at this time he is always apprehensive, not wanting to give up even a glimmer of hope, comparing the first 10, and continuing to compare the back with a slightly worse approximation.

Usually, it's about the same as comparing 30 pieces, but what if you find it in the next 40 or 50 pieces? So he would often compare 50 or even 100 pieces.

He had no distractions, threw away distracting thoughts, like a monk who was meditating, comparing carefully one by one, completely unaware of Xia Moqing and Wang Siqiang and others, who had just returned, sitting behind him calmly on the whole screen, waiting for the final result of his comparison by unconventional means

When the 38th piece was compared, he jumped up from his seat excitedly: "I found you, it's so hard to find me!" "I was so excited that I burst into tears, and I felt more relaxed and relieved than I had ever felt before.

It was an old case 28 years ago, Xia Moqing couldn't help but remind: "Xiao Tai, will it be a mistake?" Or you're right. ”

Tai Chao noticed that he had become the focus of everyone's attention, but now he didn't bother to greet the leader, so he hurriedly sat down and checked from different angles, checked six or seven times in a row, and confirmed in a resolute tone: "Director Xia, Section Chief Wang, that's it, it's wrong, it's wrong, it's wrong." ”

Xia Moqing was also excited, pointed to the phone in his hand and said, "Call your Section Chief Qi, call Director Han and Director Cui, you call, you report the good news to them." ”

Tai Chao looked at the case file and knew that this fingerprint might have been left by the murderer, but he couldn't be sure, and after thinking about it, he shook his head and said: "Director Xia, whether this old guy with a criminal record is a murderer or not, I feel that now is not the time to report good news." ”

The fingerprints were found by Wang Siqiang, and he knew the situation best.

Xia Moqing smiled and asked, "Section Chief Wang, what do you think?" ”

"801" is a collective, no matter who solves it, the most important thing is to solve the case, Wang Siqiang leaned over and looked at the suspect's photos and materials, and turned back and said: "It's best to investigate from the side first, after all, too much time has passed, and there is no evidence other than this fingerprint, so we can't act rashly." ”

"If the Commissioner was here, the Commissioner would have thought so."

Xia Moqing nodded slightly, and then said, "Xiao Tai, I will report to your Section Chief Qi first, and then your four sections will start investigating." ”

The technical police can really lead the investigation, Tai Chao was ecstatic, raised his hand and saluted: "Yes!" ”

Of course, such a major event must be reported to the director.

Han Jun had just finished the case analysis meeting when he received the call, looking at the suspect information sent by Xia Moqing, he couldn't help but smile: "Everyone, the fourth department has brought us another surprise, if the fingerprints are really left by the murderer, then our '801' is not only expected to solve a 28-year-old nameless corpse case, but even catch a boss suspect." ”

The four subjects that are the most difficult to produce results are another blockbuster, the "Huanggang 12.12 Murder and Corpse Throwing Case" can be regarded as their solution, Zhan Shengrong was under a lot of pressure, and blurted out: "Director, how to investigate tomorrow, you give an order." ”

Several directions have been determined, not how to investigate, but who will lead the inventory.

Han Jun weighed it and said with a smile: "Deng Nanqing, you are engaged in computers and understand high technology, and investigating the social relationship of the victim during the part-time job in SH is the main direction of our next investigation, and it is indispensable to deal with those communication experts, you are the most suitable, you are the commander, Zhan Shengrong, Tan Yanbing, and Sun Dayong cooperate, and Jiang is the consultant." ”

Deng Nanqing was stunned, and asked with an incredulous face: "Me? ”

"It's not you, it's me, it's decided, rest early, and start work early tomorrow." After finishing speaking, he took up the role of the shopkeeper again, pushed open the door of the carriage and walked away. (To be continued......)
