Chapter 1320

Eyes are the best-tasting part of an animal, but they are more suitable for locals.

Just like in the northwest, many people find fish eyes disgusting, and find the boiled sheep eyes delicious, while in the southeast, many people find fish eyes have a special taste, but cannot accept sheep eyes at all.

Similar ones are pig eyes and cow eyes, which are different from fish eyes and sheep eyes. They all have a bursting feeling, and they are better roasted.

Especially cow eyes, the volume is four times that of pig eyes, often boiled and then roasted. Moreover, compared with pig eyes, cow eyes are fatter, and roasted and eaten is very like Chinese-style fat, or a row of fat on the edge of steak sirloin.

If you want to use the format of "this is the piece of meat that moves the most on the cow" commonly used by merchants to evaluate, the meat around the cow eye is the piece of meat that moves the most on the cow—no meat moves more than me!

However, the cow eyes roasted by Zhang Limin, or the cow eyes roasted by the Pingzhou chef he found, were only satisfactory to Jiang Yuan.

Jiang Yuan didn't need to explain specifically, just ate a few bites and stopped his chopsticks, which already explained it.

Zhang Limin came to support the front with the provincial department's purpose, and asked: "The taste is not to your taste?"

Jiang Yuan said truthfully: "Yes. I often eat the cow eyes roasted by my father. Pingzhou flavor may not be used to it. It doesn't matter, it doesn't affect it. Usually, I eat more meat and vegetables."

"It's me who didn't think clearly." Zhang Limin slapped his head: "Just listening to the Pingzhou chef telling me stories, that... can you give me your father's phone number? I will ask my father specifically how to roast and how to season?"

"This... no need, too much trouble for you." Jiang Yuan was embarrassed.

"It's okay, it's okay, what is not to do, of course, it is to do it well." Zhang Limin said sincerely: "Give me a phone number, and I will organize the chefs to learn together."

Jiang Yuan pushed back twice, couldn't push back, and finally could only give his father's mobile phone number in Zhang Limin's fiery enthusiasm.

Zhang Limin went out in a hurry.

Jiang Yuan turned back and said to the people at the same table: "Really sorry..."

"It's okay, it should be." The Pingzhou people present waved their hands naturally: "It's mainly because you can't drink during the battle. He wants to express it but can't. He is anxious to death. You give them something to do, and they are at ease."

"Like abstinence syndrome."

"Originally, it would be fine if he was drunk, but now there is no way, so he can only get something to eat. Don't say, it's just a bit not enough."

Several people said and grabbed a rib meat, touched each other, and chewed.

Evening.

Similar to the previous battle, experts who want to rest are considered off work, and those who volunteer to work overtime can naturally return to their seats and continue to compare fingerprints.

At the same time, the criminal police officers of the Criminal Police Detachment are ready to go, ready to catch people according to the output of the experts at any time.

Jiang Yuan also returned to his seat.

Even such a big section chief came to roast cow eyes, regardless of whether he roasted it himself, at least the rice basin with cow eyes was brought by him. As a guest force that is not free support, Jiang Yuan feels that he has to compensate for a few more criminals to be reasonable.

Taking advantage of the quiet night, Jiang Yuan specifically chose a homicide case and began to ponder it carefully.

The fingerprint came from a half-way corpse found three years ago. When the corpse was found, it had already rotted into a mess. The windproof jacket on the body was of good quality, allowing the case handlers to extract some fingerprints.

Because the deceased had defensive wounds on the upper arm, the wounds were concentrated on the chest and abdomen, all of which were frontal, and there were traces of close-range blood splashing on the clothes, so it was determined by the forensic doctor at the time that there was a possibility of entanglement with the murderer. In addition, the identity of the deceased could not be confirmed, which made the identification of the fingerprints on the deceased appear more cost-effective.

Jiang Yuan called out the case file and read it, and also agreed with the conclusion in the forensic report.

Especially the traces of close-range blood splashing, it could not be sprayed on himself by the deceased, but could only be that the murderer's hand holding the knife was stained with blood, and then splashed back onto the deceased in the process of continuing to wave the knife.

Through this bloodstain, it can also be seen that the distance between the murderer and the deceased was very close at that time, so there was a possibility of entanglement with each other.

Although because the corpse was seriously rotted, the possibility of extracting DNA was lost, but the fingerprints on the windproof jacket indeed could come from the murderer, at least it was the deceased's own, or close relatives.

This gave the fingerprint identification a better foundation. Of course, it is still not as good as the fingerprints in the standard fingerprint battle, but it is also quite good.

Jiang Yuan then pulled back the fingerprint, first tried to mark it once, then ran the fingerprint database once, scanned the 20 candidate fingerprints ranked highest, and then stopped.

If it was still the level of the first fingerprint battle, Jiang Yuan now has only two choices left, and both are stupid methods. One is to mark the determined feature points as accurately as possible, mark seven if you can, and six if you can't, five is also fine.

Then, use the determined feature points to run the database, and then lengthen the list of candidate fingerprints, try to compare 50, 80, or even 100 fingerprints, see if there is any high similarity when comparing in reverse, and then specifically analyze and screen criminal suspects.

The second stupid method is the most commonly used by everyone, trying to mark feature points many times, and even guessing some blurry feature points to see if there is any gain.

Jiang Yuan in those years mastered LV3 and LV4 fingerprint identification skills. The most powerful LV5 in his hand was the image enhancement skill. Now, fingerprint identification has been integrated and upgraded to LV6, and the newly added image recognition and analysis LV5 is more comprehensive than image enhancement...

As a result, Jiang Yuan only tried a few times and determined in a very short time... this road is impassable.

At the very least, it is also an exceptionally arduous probability road, which may take two or three days to squeeze a little bit of opportunity from the stupid method.

After a little thought, Jiang Yuan took out his mobile phone and called Liu Zhuangshi, saying: "I saw a case and want to extract evidence. Can it be done?"

Liu Zhuangshi, who was soaking his feet at home, looked up at the dark night outside the window and said: "Very can, no problem, you send the case file number to me, I will let the evidence room people report now."

The working hours of the evidence room are relatively fixed, and nine-to-five is not a problem. But today Jiang Yuan made a request, so it is not an ordinary day.

Jiang Yuan pondered and added: "I estimate that I need to use the criminal science laboratory. High-resolution microscopes and physical and chemical laboratories are needed."

"No problem, I will let the criminal science people go to work." Liu Zhuangshi said without pity.

"See you in a while." Jiang Yuan said and ended the call.

Liu Zhuangshi's feet were soaked in hot water, slightly hesitant, and began to do reading comprehension: Jiang Yuan said see you in a while. By reason, it should be saying see the people in the laboratory and evidence room in a while, but he might also default to in a while, I will also go over?

Liu Zhuangshi thought again: That's right, Jiang Yuan is working overtime, and I am soaking my feet at home, preparing to sleep. The things done by such people, if said out, will definitely be treated as not human. So, Jiang Yuan actually defaults that I should be a person?

Liu Zhuangshi, who felt Jiang Yuan's deep meaning, did not hesitate anymore, pulled his feet out of the bucket, and shouted: "Wife, I have to go to the unit."

"Now? I see you don't want hair!" The wife rushed over and put a cup of ginseng tea heavily on the table: "You find clothes yourself."

"I find it myself, find it myself." Liu Zhuangshi hurriedly picked up the ginseng tea, drank it, put on his clothes and ran outside.

Conference room.

Zhu Huanguang looked at the fingerprints, suddenly saw Jiang Yuan get up to pack things, couldn't help but look at the time, and then smiled, stretched, and prepared to chat a few words on the way.

At this time, he saw two police officers holding an evidence box each and walked in, and then reported directly to Jiang Yuan.

Zhu Huanguang was stunned, and simply walked up.

He was not the only one curious, several people gathered around.

Jiang Yuan didn't cover up, opened the evidence box on the spot, found the windproof jacket, and said: "I am preparing to take a few fingerprints again."

"Ah? Take it now? It's not easy to take."

"This material... is very difficult to take."

"If fingerprints have been taken before, everything that should be destroyed has been destroyed."

Several people present were also experts in their respective units, and naturally put forward opinions.

Jiang Yuan nodded slightly, only saying: "I am preparing to try some new technology."

"You still have time to study new technology?" Zhu Huanguang first expressed surprise. He often pays attention to the cases handled by Jiang Yuan, not to mention the specific difficulty and the experience consumed, just in terms of quantity, it exceeds most people. In this case, where is the time to engage in new technology.

Jiang Yuan had no way to explain, and didn't need to explain, only saying: "It can be considered as a little gain during the case handling. I don't need to take complete fingerprints. My idea is to take a few more residual fingerprints, merge and process them, and then compare them in the database. Maybe there will be discoveries."

LV6 fingerprint analysis method, stacking a temporary 1 is LV7, that is the world's top fingerprint analysis method. You say whether this technology is new or not.
