1995, Starting as a Criminal Investigation Expert

Tang Weidong, along with Lin Huiquan from the Tingyang Municipal Bureau, rushed to the scene together.

The two people hadn't come over, so I thought it was just a regular murder case.

Who knew they'd use grenades and make such a big commotion?

Tonight, the topic of conversation among the city's residents after dinner will definitely not be who performed better at the City Games, but rather the gunfight that broke out in Baizhuang Village, where the police even used grenades.

Xu Qiang gave a report, and surprisingly, he wasn't scolded.

After listening to the conversation, Tang Weidong felt that Xu Qiang's judgment on the suspect's movements was quite accurate, and there were no problems with the entire on-site command process.

The reason it turned out this way is purely because Zheng Cheng is a madman and unexpectedly possesses heavy weapons.

He didn't linger and rushed to the city hospital to visit the injured Old Zhou.

yard.

Li Shu drew lines on the cement ground, had someone take pictures, and then carefully picked up a bullet casing and put it into an evidence bag.

Not far away, Peng Rong was helping Qin Wenbao and the others carry the body.

As a result, Zheng Cheng's abdomen was torn open, and a lump of intestines slid out.

"Holy crap."

Peng Rong was completely devastated.

Originally, because the body was badly mangled by shrapnel, he was helping to support the buttocks at Qin Wenbao's request. Now, the intestines have slid all over his arm.

Qin Wenbao quickly gestured for him to put it down.

Peng Rong disgustedly pulled his hand away, turned around and rushed out of the yard, running to the nearby ditch to wash himself thoroughly.

When he returned, he couldn't help but say, "What do you guys think this guy is thinking? In this situation, he has to go through with it, doesn't he? Can't he just surrender?"

It's not like you have hostages or a chance to escape, so you won't surrender.

You have nothing but two grenades. Do you really think you can fight your way out?

Anyway, Peng Rong had seen some ruthless bandits who always claimed they weren't afraid of death, but when it came to the moment of death, none of them were unafraid.

Zheng Cheng, on the other hand, was so enraged by the fumes that he grabbed a grenade and tried to take everyone down with him.

Li Shu picked up another bullet casing; the yard was full of them. He said, "Yes, it is a bit strange."

Instead of running away when he could, he went and killed that woman.

Then they were surrounded, but they refused to surrender and insisted on fighting to the bitter end.

It's not that there are no people in the world who aren't afraid of death, but Zheng Cheng doesn't seem like that kind of person.

He has a strong sense of counter-surveillance. In the case of Yang Luxiang last year, his method of committing the crime was clean and efficient, and the scene was handled cleanly.

They are also good at hiding.

The task force investigated him last year but found nothing unusual.

If I hadn't extracted his fingerprints this year, I wouldn't have been able to identify him.

Tan Guoxiong had told himself that when he was collecting Zheng Cheng's fingerprints, he only thought that the man was very cooperative and honest, and he never expected it to be him.

The key point is that this person is also smart, with an absolutely high IQ.

After their fingerprints were collected, they immediately realized they had been exposed and promptly fled.

His entire evacuation was not planned in advance; it was a spur-of-the-moment decision.

The result is that one might think of luring the tiger away from the mountain and playing tricks on the underworld.

Li Shu felt that even if he were in Zheng Cheng's shoes, he would never have been able to do what Zheng Cheng did.

Such a person couldn't possibly not understand that if he was trapped in the yard and couldn't escape, the most reasonable choice would be to surrender.

But he didn't, and after thinking about it carefully, Li Shu really felt it was a bit strange.

Zhao Yong said, "What's so strange about that? He has a murder case on his hands, he knows he's doomed, so he's putting up a last-ditch effort."

That is indeed a reason.

When Xu Qiang tried to persuade him to surrender, Zheng Cheng also said that he had several lives on his hands and would die if he were captured.

I just don't know exactly how many lives he meant when he said "several lives".

Including Huang Youjun and his mother, that makes three lives lost.

Given Zheng Cheng's fierceness, it seems a bit lacking.

Also, this guy has both grenades and submachine guns; surely he wouldn't be hiding them for self-defense?

"Do you think he has other cases besides Yang Luxiang's case?" Li Shu asked.

Standing at the entrance of the courtyard, waiting for the investigation to finish, Xiao Rui asked, "Li Shu, what do you mean?"

Li Shu explained his thoughts.

"That's true."

Xiao Rui nodded slightly, then said, "There's one more thing. You see, he had over 60,000 yuan in cash in his bag. That's no small sum. Why didn't he deposit it in a bank?"

"I remember when we investigated him last year, he seemed to have opened some kind of audio-visual store with someone, and he was smuggling videotapes from Yuehai to here. I don't know if the store is still open. If it is, then these tens of thousands of yuan might be payment for goods."

"But if it's not open, having so much money at home makes it look a bit like a robbery."

Generally speaking, robbers rarely deposit stolen money into banks.

These guys just love real cash; they keep all their money on them for easy spending and also for easy escape.

And as Li Shu said.

Who keeps a couple of hand grenades hidden in their house for no reason?

If we have guns, then of course we'll use them.

"Old Zhao, have those two guns tested for bullet marks and see if they match up with previous gun-related cases. I think Li Shu is right, that bastard might have something else going on."

Xiao Rui gave him a word of advice, then turned to discuss it with Xu Qiang.

His thinking was correct. The person was already dead, so comparing the guns was the best way to investigate whether there were any other cases before.

Anyway, I was going to keep these two guns anyway, so it was just a convenient thing to do.

After dealing with everything at the scene, it was already afternoon when I got back to the station.

The detachment is quite busy and hasn't come here.

With some time left before getting off work, Li Shu went with Zhao Yong to conduct gun and ammunition experiments at the city bureau's firing range.

This place is right next to Zhui Feng's hideout. There's a small playground there, where anyone with plenty of energy can come and exercise.

Their daily training also takes place here.

When they passed by, the other two police dogs hadn't returned yet, so Zhui Feng lay motionless at the cage opening, dozing off.

But as the group passed by, they immediately raised their heads warily.

"Brother Yong, these police dogs are really useful. Why don't you train more of them?" Li Shu said.

Li Shu hadn't realized it before, but after this case, he discovered that police dogs are really useful when used properly.

They found the suspect by following the scent.

Zhao Yong glanced at Zhui Feng and said, "The key is that there's no one here. And do you think training police dogs is just about making them sit or stretch out their arms? Let me tell you, it's difficult. They have to go to Ningshan for training, and the training fees aren't cheap."

"Also, now that we have the personnel, we need to buy police dogs too. Do you know how much a well-trained police dog costs?"

Li Shu shook his head and asked how much.

Zhao Yong raised one hand.

"five hundred?"

Li Shu tentatively asked.

In rural areas, people would rather spend five yuan to buy a dog to guard their home.

These are police dogs, after all, selected from the best of the best. This German Shepherd, for example, would probably have to be imported from abroad, which would certainly not be cheap.

Zhao Yong's eyes widened: "It's five thousand, and that's still the internal cost price."

"How many?"

Li Shu's eyes widened. It was so expensive! It was worth a year's salary of his.

"What do you think?" Zhao Yong explained, "You don't know, these police dog breeds are all imported from abroad, which requires foreign exchange. All in all, one puppy costs at least one or two thousand."

"Then there's the success rate. Out of ten police dogs, maybe only three or four will be successfully trained, and the rest will be eliminated. And the training takes one or two years, and they eat meat every day, which costs a lot of money."

"Five or six thousand apiece, that's really not expensive."

It is precisely because of the high cost that Han Jianjun is considering breeding his own bloodline.

Upon closer reflection, Li Shu realized it was true.

The system has relevant information; I've glanced at it a few times, and it says that police dog training is very difficult.

After all, it's an animal and can't understand human language.

However, the next moment, Li Shu thought that since the system had relevant data and technology, and was more advanced, could he try to help the team train police dogs?
