Chapter 1410 - 1334: New Technology
The eyes are the most delicious part of an animal, but they’re more suited to the locals.
It’s like in the Northwest, many people find fish eyes disgusting, yet think that sheep eyes cooked are incredibly delicious. In the Southeast, many people find fish eyes uniquely flavorful but can’t accept sheep eyes at all.
Similarly, there are pig eyes and cow eyes, which are different from fish and sheep eyes; they both burst with juice and are tastier when roasted.
Especially cow eyes, they are four times the size of pig eyes and are often cooked and then roasted. Moreover, compared to pig eyes, cow eyes are even fattier. They taste like Chinese fatty brisket or the strip of fat on a Western sirloin steak when roasted.
If using the common merchants’ phrase "This is the most exercised part of the cow" for evaluation, the meat around the cow’s eyes is indeed the most exercised part — no meat understands activity better than me!
However, the cow eyes roasted by Zhang Limin, or rather, by the Pingzhou chef he recruited, were only satisfactory at best for Jiang Yuan.
Jiang Yuan didn’t need to elaborate, stopping after a few bites already indicated enough.
Zhang Limin, who was there with the provincial office’s directive to support, couldn’t help but ask, "Not to your taste?"
Jiang Yuan candidly said, "Yes. I’m used to the cow eyes my father grills. Maybe the Pingzhou flavor isn’t something I’m accustomed to. It’s no big deal; I usually eat a lot of meat and vegetables anyway."
"I couldn’t figure it out," Zhang Limin smacked his forehead. "I just listened to the Pingzhou chefs’ stories. Could you give me your father’s number? I’d like to ask him how he grills and seasons it specifically."
"There’s no need for that; it’s too much trouble for you," Jiang Yuan said, embarrassed.
"It’s no trouble at all. Whatever we’re doing, it should be done well," Zhang Limin said sincerely. "Give me the number, and I’ll organize the chefs to learn together."
Jiang Yuan tried to decline, but couldn’t. In the end, under Zhang Limin’s fiery enthusiasm, he reluctantly gave out his father’s phone number.
Zhang Limin left in a rush.
Jiang Yuan turned back and apologized to those at the same table, "I truly apologize..."
"It’s nothing, don’t worry," the Pingzhou locals waved naturally. "Mainly, during large-scale operations, we can’t drink. He wants to show appreciation but can’t, so he’s really anxious. Giving them something to do settles them down."
"Like alcohol withdrawal syndrome."
"In the past, they could just drink till they dropped. Now they can’t, so they have to involve themselves with food. To be honest, it’s just lacking something."
The group continued talking and grabbed a rib each, clinking them together and devouring them.
...
Evening.
As with previous operations, those experts who wanted to rest were off duty, while those who volunteered for overtime could return to their seats and continue fingerprint analysis.
Meanwhile, police officers from the Criminal Police Brigade were on standby, ready to apprehend suspects based on the experts’ findings.
Jiang Yuan returned to his seat.
With someone like the department head personally involved in roasting cow eyes, whether he did it himself or not, at least he was the one who brought the dish in. As an external expert offering non-free support, Jiang Yuan felt it was only reasonable to offer them a few more criminals in return.
Taking advantage of the quiet evening, Jiang Yuan deliberately chose a murder case to ponder over carefully.
The fingerprints came from a roadside corpse discovered three years ago. By the time it was found, the body was badly decomposed, but the windbreaker remained in good condition, allowing the investigators to extract some fingerprints.
Since the deceased had defensive wounds on the upper arm, with stab wounds concentrated in the chest and abdomen, all frontal, and there were signs of close-range blood spatter on the clothes, the forensic doctor concluded that there might have been a struggle with the murderer. Adding to this was the uncertainty about the deceased’s identity, making it more worthwhile to identify the fingerprints.
Jiang Yuan examined the files and concurred with the forensic report.
Especially the close-range blood spatter, it couldn’t have been sprayed onto the deceased by themselves; it could only have been flung onto them by the murderer’s blood-stained arm during continued stabbing.
The blood spatter also indicated that the murderer and the deceased were very close at the time, suggesting a potential struggle.
Although the body’s severe decomposition made DNA extraction impossible, the fingerprints on the windbreaker could possibly belong to the murderer, or at the very least the deceased themselves or a close relative.
This provided a solid basis for fingerprint identification. Of course, it still didn’t match the standard found in fingerprint battles, but it was quite decent.
So, Jiang Yuan brought back the fingerprints, tried marking them once, then ran them through the fingerprint database, scanning the top 20 candidate fingerprints, and stopped there.
If he were still at the level of a newbie to fingerprint battles, Jiang Yuan would have only two choices, and both would be cumbersome methods. One, mark the identifiable trait points as accurately as possible; if you can mark seven, then do so. If not, six, or even five will do.
Then, use the trait points to run database searches again, extending the list of candidate fingerprints, comparing 50, 80, or even 100 fingerprints to see if there’s a good match, and further analyze and screen suspects.
The second cumbersome method, the most commonly used, involves multiple attempts to mark trait points, even speculating about some vague ones, to see if anything emerges.
When Jiang Yuan was a beginner, he mastered Level 3 and Level 4 fingerprint identification techniques. His most advanced Level 5 skill was Image Enhancement. Now, fingerprint identification has upgraded to Level 6, and the new Image Recognition and Analysis at Level 5 is even more comprehensive than Image Enhancement...
So, Jiang Yuan tried a few times and quickly determined... this path wouldn’t work.
At least, it was a very exhausting probability path that might take two to three days to squeeze out a slight chance using the cumbersome method.
After a brief consideration, Jiang Yuan picked up his phone and called Liu Zhuangshi, asking, "I spotted a case I want to extract evidence from. Is it feasible?"
Already home soaking his feet, Liu Zhuangshi looked up at the dark night outside the window and said, "Absolutely, no problem. Send me the case file number, and I’ll have the evidence room staff report right now."
The evidence room has a relatively fixed schedule, typically 9-to-5 on weekdays, but today since Jiang Yuan requested it, it became an extraordinary day.
Jiang Yuan considered further, "I might also need to use the Criminal Science lab, including high-resolution microscopes and the physical and chemical laboratory."
"No problem, I’ll have the Criminal Science staff come in," Liu Zhuangshi said without hesitation.
"See you soon," Jiang Yuan concluded the call.
Liu Zhuangshi’s feet were soaking in hot water, and he hesitated slightly, beginning to parse Jiang Yuan’s words: Jiang Yuan said "see you soon," which logically meant to meet the lab and evidence room staff soon, but could he have meant that I should also go later?
Reflecting a moment, Liu Zhuangshi thought: Yes, Jiang Yuan is working overtime, and here I am at home relaxing, getting ready to sleep. That’s the sort of thing no responsible person would do. So, Jiang Yuan must be implying that I should act like a responsible person?
Feeling Jiang Yuan’s deeper meaning, Liu Zhuangshi wasted no time, pulling his feet from the tub, and called out, "Wife, I have to go to the office."
"Now? You’re asking to lose your hair!" His wife rushed over, placing a cup of ginseng tea heavily on the table. "Get your clothes yourself."
"I’ll get them myself, definitely," Liu Zhuangshi quickly drank the tea, then dressed and dashed out.
Meeting room.
Zhu Huanguang examined the fingerprint, suddenly seeing Jiang Yuan stand up and pack his stuff, and couldn’t help checking the time, then smiled and stretched, planning to catch up for a chat.
Just then, two officers walked in carrying evidence boxes, directly reporting to Jiang Yuan.
Zhu Huanguang was taken aback and approached.
Curiosity wasn’t confined to him; several others gathered around too.
Jiang Yuan didn’t hide anything, opened an evidence box on the spot, pulled out the windbreaker, and said, "I plan to try extracting a few more fingerprints from here."
"What? Trying now? Isn’t it difficult?"
"This material... isn’t it hard to extract from?"
"If fingerprints were already taken, wouldn’t the necessary parts be damaged?"
The experts from various units naturally raised their concerns.
Jiang Yuan nodded slightly, only saying, "I plan to try some new technology."
"You still have time to research new technology?" Zhu Huanguang first expressed surprise. He frequently followed Jiang Yuan’s cases; not speaking of the difficulty and experiences required, the sheer volume surpasses most people. In this situation, where’s the time for new tech research?
Jiang Yuan had no explanation nor the need to explain, simply saying, "It’s something I slightly acquired during past cases. I don’t need to extract complete fingerprints; my idea is to pull out several partial prints, merge them, and run them through the database. Maybe there’ll be a breakthrough."
With the Level 6 fingerprint analysis technique, stacking a temporary +1 achieves Level 7, representing the world’s top-level fingerprint analysis. You tell me, is this new or not?
