1995, Starting as a Criminal Investigation Expert

Tan Guoxiong's face showed utter speechlessness.

"Can't we speak like normal people?"

You solved 14 cases in one afternoon. How are those veteran detectives supposed to feel?

Li Shushun hooked his arm around Tan Guoxiong's shoulder.

We're brothers, why are you jealous?

"I'm not bragging, I genuinely think it's too little. If you don't believe me, I'll do the math for you and you'll see."

Li Shu pointed to a large pile of files on the floor next to the table and said, "I compared 106 fingerprints this afternoon. That's a normal speed, you know."

Tan Guoxiong nodded. "That's right, that's normal. You continue, and I'll continue listening."

Li Shu countered, "Out of 106 cases, only 14 were matched. Do you think that's a lot?"

Tan Guoxiong glanced at Li Shu. Hmm, not many.

Li Shu, completely oblivious, continued, "And you have to think about it, a large part of the reason why fingerprints didn't match in these cases back then was because manual fingerprint matching was too inefficient and prone to errors. If the fingerprints were even slightly substandard, they wouldn't match."

"Now that we have the AFIS system, we should generally review these old cases. And this first review should have the highest probability of finding a match."

"As a result, out of hundreds of cases, only 14 were correct, which I think is too few."

"Alright," Tan Guoxiong interrupted Li Shu, "If you say it's less, then it's less."

When you send it back to the brigade, you'll see they say it's not too little or too little.

While helping Li Shu organize the case files, Tan Guoxiong hesitated for a moment before saying, "Li Shu, could you teach me how to compare fingerprints?"

We entered the municipal bureau together, starting from the same point.

Logically speaking, in the tortoise and the hare race, it's okay if one is a little slower.

The problem is, this rabbit is on a rocket; it's already broken out of the atmosphere.

They're all brothers, and Tan Guoxiong isn't jealous, but he really doesn't want to fall too far behind.

Li Shu raised an eyebrow slightly.

If this gets back to Old Man Zhang's ears, he'll come all the way to Nanjiang and beat you up.

Tan Guoxiong thought Li Shu's strange look meant he was wondering if fingerprint matching really needed to be taught, so he sighed and said, "I used to think I knew how to match fingerprints, but now, I feel like I don't anymore."

They were all taught by the same teacher, and I didn't see them secretly giving you extra lessons.

Li Shudao said, "Okay, I'll teach you everything I know. But in return, can we skip the pickled vegetable porridge tonight? I want braised pork."

Tan Guoxiong's expression froze, and he said awkwardly, "Then how about we go out to eat instead?"

Braised pork belly? No way.

After finishing, the two of them took the matching files to the brigade.

For criminal police officers, leaving get off work on time is simply a luxury.

"What is this?"

Xiao Rui and Lin Wanping were not there, but another deputy captain, Hu Guoen, was. When he saw the two of them carrying a pile of files, he casually asked a question.

"Good news."

Li Shu smiled and pulled Tan Guoxiong away.

Hu Guoren, unaware of the situation, flipped through the files and saw the printed fingerprint files. He immediately realized that they were old cases where the fingerprints matched.

I quickly checked the thickness, did a hasty count, and was immediately dumbfounded.

Starting at 14? Are you kidding me?!

It's an old case, you can leave it there. You can think about it, but there's no rush.

But once you make a match and identify the suspect, things change.

Should the suspect be arrested?

After so many years, should the case be reviewed again to investigate the relationship between the suspect and the case?

This doesn't mean that Li Shubi simply matched the suspect with someone, arrested them, and that was the end of it.

If the case closure report is completely blank, and only includes a fingerprint identification report without mentioning the procuratorate, the leaders will definitely beat them senseless.

Therefore, for each case, manpower must be invested to clarify the ins and outs.

For older cases, even more effort will be required.

Fourteen cases have been brought in at once, plus the three murders that came before. It seems like they're going to have to live in the team.

So the next day, Xiao Rui brought breakfast and ambushed Li Shu early in the morning.

They requested that Li Shu take a rest first.

"Li Shu, I only have this many people, it's really not enough."

Xiao Rui poured out his grievances.

The message was simple: let Li Shu rest for a while.

Zhao Yong, who was standing next to him, joked, "Old Xiao, you guys always complain that we're too slow in producing the test reports, but now that it's fast, you're still not happy."

Xiao Rui smiled wryly: "The key is that Li Shu is moving way too fast."

Fourteen cases a day, who can handle that?

"By the way, you should work on the murder case first. Old He asked you to help with that Yang Luxiang family annihilation case, so you should study that first."

Murder cases are tough nuts to crack; they're not easy to tackle.

Li Shu agreed.

It's a good time to take a break and write my thesis.

For example, I could probably write an article about my experience using high-altitude coating machines and the scenarios I would be able to handle.

There's also the case of Zhou Pan robbing a taxi, and the effect of EOS dye on dark carriers. If you add a little water, it becomes two papers.

However, since we promised He Chenghua about Yang Luxiang's case, we can indeed study it before the coating machine arrives.

Li Shu called Tan Guoxiong and they went to the archives to move files.

For cases like this, case files are essential.

In his private room, Li Shu made tea for the two of them and looked through the case files.

The incident occurred on June 28, 1994.

The location is in Chongning District, Guangyuan Street, which is where Jin Zhenjiang's house used to be.

This Yanglu Lane is not far from the furniture market.

Originally, two wealthy families, surnamed Yang and Lu, lived here, which is why this alley was quite lively.

It's now just a large area of ​​residential houses.

The crime scene was one of the houses not far from the river.

The victim, Kang Guiying, was 65 years old when she died.

The other victim was her son, Huang Youjun, who was 44 years old when he died.

Their family moved to Nanjiang in the early days of the People's Republic of China. They didn't have many relatives there, and Huang Youjun was an only child, so the case of the entire family being wiped out wasn't really a problem.

"Look."

Tan Guoxiong handed over a photo from the scene, his eyebrows furrowed.

Li Shu glanced at it and felt a wave of physical discomfort.

The main subject of the photo is a freezer, branded Aucma.

Then, inside the freezer, there were only two lumps of rotten meat, stuck together, soaking in dark red blood broth. The part above the water was already in a state of extreme gigantism.

Because there was pork in the freezer before, after a piece rotted, the maggot eggs inside hatched and multiplied wildly.

As a result, many places were crawling with maggots.

Even through the photo, Li Shu could imagine the shock his colleague must have felt when he arrived drawn by the stench and unexpectedly yanked open the freezer.

That stench could probably blow your skull open.

This pile contains Huang Youjun and his mother.

After the two were shot, the suspect stuffed them into a freezer.

It was frozen at first, and no one noticed.

In June, the power company repeatedly came to Kang Guiying's door to post electricity bills and urged her to pay the bills, but to no avail. On June 13, they cut off the electricity to Kang Guiying's house.

The body was thawed.

It was mid-June, and the temperature in Nanjiang was around 30 degrees Celsius. In such a hot weather, even the most airtight freezer couldn't contain a corpse that had been rotting for half a month.

During those days around the 28th, the neighbors next door could always smell a foul stench.

After much searching, it was finally determined that the virus originated from Kang Guiying's home.

Because they hadn't seen Kang Guiying for a month, they were afraid something was wrong and chose to call the police.

Police from the Guangyuan Street Police Station responded to the call and pried open the door, only to discover that the mother and son had been dead for a month.
