1995, Starting as a Criminal Investigation Expert

The lesson was over, and the results were unexpectedly good.

A group of people surrounded them, asking all sorts of questions.

First, Lin Huiquan inquired in detail about the AFIS system.

Li Shu dared to say that he definitely didn't understand.

But when he heard that this thing was thousands of times more efficient than a human in comparison, his expression changed immediately.

"No wonder the news broadcast keeps saying that science and technology are the primary productive force; it's terrifying."

Thousands of times.

Upon hearing Li Shu's reply that he was probably the only one in the municipal bureau who knew how to use this system, his expression changed again.

"What a pity!"

Lin Huiquan sighed. Li Shudu had said that machines were only the first step, just tools; the key was still people.

Even if the Tingyang Municipal Bureau gets its own AFIS system, it will still need an expert like Li Shu to oversee its use.

Unfortunately, just as Guo Xiangyang said, Tang Weidong would definitely not let go of such a talent.

It's already good enough that they didn't transfer talent from the Municipal Bureau; how could they expect you to poach them?

"Li Shu, you'll have to help out a lot when there are cases later," Lin Huiquan said.

The criminal police officers present nodded in agreement.

They only began to understand the meaning after hearing the rest.

Everyone knows that fingerprint comparison is useful; it can become irrefutable evidence and a powerful tool for solving cases.

The problem is that in actual work, fingerprint comparison is slow and has a low success rate.

If you encounter incomplete fingerprints, you're completely lost.

As Li Shu said, if even incomplete fingerprints can be matched, it will be of great help in solving cases in the future.

If we encounter a case later, we can definitely contact Li Shu more often to help with the comparison.

When it was Guo Xiangyang's turn, he simply said, "I'm impressed."

He patted Li Shu on the shoulder and said with emotion, "It's just like computers. From now on, it's your world, young people's world. To be honest, we old guys are really falling behind the times."

He still can't figure out how a computer, which is full of electronic components, could recognize fingerprints.

These words were a bit harsh, so Li Shu quickly became modest and said that he still had a lot to learn from them.

"Come on, what are you trying to learn from me? I have nothing to teach you." Guo Xiangyang snorted, his eyes full of admiration as he looked at Li Shu.

It's about time, so we should definitely treat them well.

Lin Huiquan had another meeting and didn't go, so Guo Xiangyang and Tian Yu went in his place.

After finishing their meal, Li Shu was about to go back with Guo Xiangyang and the others to answer some of the questions they hadn't figured out when Tian Yu stopped him.

He called Li Shu aside, said a few nice words first, and then said, "Li Shu, what if there's a situation where several blood fingerprints are incomplete?"

"Didn't you also say that too much blood will fill the furrows between the lines, making it a blurry mess and making it impossible to see the details?"

"What about scratches and overlapping fingerprints? What I mean is, is there any possibility of a match between fingerprints under these conditions?"

Upon hearing this, Li Shu understood; there was a case involved.

"Team Leader Tian, ​​do you have a case to solve?"

Tian Yu nodded.

However, when Li Shu asked for details, she said she couldn't explain it clearly in a short time and asked Li Shu if she had time.

Li Shu glanced at Guo Xiangyang in front of him and said that he would go find Tian Yu after he finished here.

After Guo Xiangyang and the others finished, Li Shu found Tian Yu.

"There's a case like this, from 91, in our jurisdiction. It involved a girl, a college student. She was working overtime at the factory that night and was walking home late when she was attacked on Hengchun Road. Her wallet was stolen, and we still haven't found the thief," Tian Yu sighed.

Li Shu asked if the victim was dead.

Tian Yu shook his head.

Peng Rong interjected, somewhat puzzled, "Team Leader Tian, ​​back in '91, there were probably at least eight hundred, if not a thousand, cases of highway robbery a year."

He was trying to say that it had been several years, so why was Tian Yu still thinking about this case?

Clearly, you've hit the nail on the head.

Tian Yu hesitated for a moment, unsure how to explain, then suddenly stood up and said, "How about this, why don't you come with me?"

Right now, I'm riding a motorcycle with the two of them straight to Zhaqiao Town, which is below Tingyang.

It's not far.

The destination is a village on the outskirts of the town.

He hadn't driven far into the village when he suddenly stopped.

"there."

Tian Yu winked at someone in the distance.

Li Shu looked over.

There were two people in front of a house.

One male and one female.

The man, who was standing with his back to her, was probably a young man and was talking to the remaining girl.

The key is this girl.

She lay motionless in that extended, possibly modified, wheelchair, covered with a thin blanket. Then she turned her head, perhaps because the man had told a joke that made her giggle.

The girl looked to be in her early twenties.

I don't know if it's because she's been lying down for a long time or what, but her skin is snow-white.

She has an oval face, big eyes, and striking features; she's exceptionally beautiful.

"Team Leader Tian, ​​what's wrong with her...?" Li Shu was secretly shocked.

Tian Yu sighed and said, "That blow to the back of the head caused high-level paraplegia."

Li Shu was startled again.

A college student, in the prime of their life, suffering from high-level paraplegia—that's just too tragic.

Peng Rong interjected, asking who the man was.

Tian Yu didn't get close, just watched from a distance, and said, "Her boyfriend, she met him after she became paraplegic, he's a pretty good young man, he's never abandoned her."

Li Shu nodded.

If that's the case, then it's indeed not easy.

I instinctively wanted to ask about the case, how the investigation was conducted, and why the suspect wasn't found, but I swallowed the words back.

For several years, Tian Yuneng has kept this in mind, which means he must have done a lot of investigation work, exploring every possible avenue.

"Team Leader Tian, ​​were some incomplete fingerprints extracted from the scene, but haven't been matched yet?"

Since they specifically sought me out, they must be trying to start with my fingerprints.

Tian Yu nodded and gestured for the two to walk back.

Clearly, he didn't intend to bother them, and as they walked, he explained, "Our analysis suggests that the suspect might be a novice who doesn't know his own strength."

"After I knocked, I realized the person wasn't moving, and that's when I got scared. I probably touched the back of the victim's head, which is why my hands were covered in blood."

"Then he checked the victim's breathing and left fingerprints and handprints on the victim's nose, face, and even clothes."

"Fortunately, someone discovered it early and the person was saved. However, because of the rescue, the doctor may have been aware of the situation, but the person who called the police was not. As a result, the fingerprints on the victim's body were wiped away and covered by blood, making them basically unusable."

"Fortunately, we found the suspect's bag in a nearby corner. We extracted some fingerprints from the bag strap and the wallet inside. However, they were all the same, with some overlapping, some blurry, and some missing."

"Old Guo and his team studied it for a long time, and even sent it to your municipal bureau. They had Captain Han compare it, and they all thought the conditions were not good and it was worthless."

"I listened to your lecture today, and I was wondering if you had any way to help us find this person from this incomplete fingerprint."

Li Shu understood and noticed Peng Rong giving him a meaningful look, probably trying to dissuade him from agreeing too easily.

Li Shu also knew that, after all, it was a case from 91, and four years had passed, so it would definitely be difficult to investigate.

After thinking for a moment, Li Shu nodded and said, "Team Leader Tian, ​​how about this? I'll go and look through the files later. Our team should have them on file. I'll study them first and then give you an answer, okay?"

When a case comes up, there's no reason to turn it away.

Tian Yu was overjoyed and quickly thanked them, insisting on treating the two of them to another meal.

The two quickly declined, saying they had to go back to the municipal bureau.

As soon as Tian Yu turned back into the station and walked away, Peng Rong hurriedly said, "Li Shu, are you crazy? You dare to agree to this case?"

Bloody fingerprints, blurry, overlapping, incomplete—even a god would have a hard time with fingerprints like these.

Li Shu quickly replied, "Senior brother, I didn't say I would accept it. I just said I'd do some research."

Peng Rong said, "Then you'd better just do some research."

Anyway, he felt there was no chance.

He added, "Also, have you noticed why Captain Tian is so fixated on this case?"

It's a four-year-old case.

Moreover, as Peng Rong said, there are at least 800 to 1,000 such highway robberies a year.

"Why do you know?" Li Shu asked rhetorically.

In 91, Peng Rong had just graduated and probably didn't know about the case.

Peng Rong chuckled and said, "Didn't you notice the family photo on Captain Tian's table? The victim looks a lot like Captain Tian's wife. Maybe that's why he can't forget her."

Li Shu was startled; he hadn't noticed at all.

After finishing his sentence, Peng Rong added, "But to be honest, that girl is beautiful, and it's such a pity that she's paralyzed at such a young age and is living a life worse than death."

Li Shu nodded, recalling the girl's smile.

Given this situation, it's not easy to not give up on yourself and still live on strongly.
