Chapter 790

Criminal Police Brigade.

Lei Xin urgently sorted out the home-invasion burglary cases that had occurred recently, and by the way, invited all of Zhu Tianwei's colleagues back to assist in the investigation.

After Jiang Yuan finished the scene investigation and returned, Lei Xin sorted out all the criminal suspects.

"It's not troublesome. Basically, they are all recidivists." Lei Xin sighed and brought up the old topic again: "The public security situation in Qinghe City is very severe. These people used to eat with Jianyuan. Suddenly, their income was cut off, and they couldn't do anything else, so some people started to engage in traditional crimes."

"They are just lazy. Eating with Jianyuan was too comfortable, but ordinary people are all honestly doing things. Even if being a porter is particularly hard and the income is not high, that is not a reason for them to steal from others and eat from others." Liu Jinghui was in his forties, and when he talked about these things, he still seemed too indignant.

As the captain of the criminal police brigade, Lei Xin had long since stopped being so cynical, and he couldn't do what Liu Jinghui did, scolding whatever he wanted. He could only shake his head and say: "It's not to excuse them, it's just that the reality is indeed more complicated. I actually want to say that our current situation in Qinghe really needs Team Leader Jiang to sit in town."

He made the request jokingly, a bit of a half-true, half-false probe.

Jiang Yuan was flipping through the files, raised his head, and said: "I am planning to stay for a few more days. I hope Captain Lei won't find us annoying."

Ningtai County is subordinate to Qinghe City. Although the Ningtai County Bureau and the Qianjin District Bureau are at the same level, the Qinghe City Bureau is the superior unit of the Ningtai County Bureau and also has the power of business guidance over the Ningtai County Bureau. In the past two years, Huang Qiangmin has been running around, which is beneficial to both the Ningtai County Bureau and the Qinghe City Bureau, but it is mainly beneficial to Ningtai County. The Qinghe City Bureau can be considered to have cooperated very well.

Seeing that the public security environment in Qinghe City has changed, under the circumstances that the Ningtai County Bureau has the ability to help, it should still help as much as possible. Not to mention that criminals in Qinghe City will run around and easily breed a criminal environment, there is no need to wait for the Qinghe City Bureau to give orders or anything.

Lei Xin was pleasantly surprised and hurriedly said: "Really? Oh my, that's great. If you say so, we can rest assured..."

"The cases still have to be done one by one." Jiang Yuan smiled and said: "This case of Zhu Tianwei is mainly a problem of evidence collection now. Let's handle his case first, and then look at it. En, we can handle this batch of home-invasion burglaries along the way."

"Home-invasion burglary really cannot be underestimated. It is basically an advanced crime." Liu Jinghui gave a sentence.

Home-invasion burglary requires entering the burglar's residence, which is much riskier than stealing outdoors or on a bus. In addition, thieves must learn at least one skill of picking locks or climbing walls. Just this learning cost is not something that brothers who have just entered the burglary door can afford.

At the same time, the criminal experience and courage required for home-invasion burglary are also not small. Home-invasion burglary is very easy to turn into home-invasion robbery, home-invasion assault, or even home-invasion murder. Because of this, the criminal law's crackdown on home-invasion burglary is far greater than ordinary theft.

Therefore, home-invasion burglary is an advanced crime, an advanced direction chosen by the little minions who have entered the rivers and lakes.

The effect of this advanced path is also very significant. First of all, the income is relatively high. For one home invasion, there are cases of hundreds or thousands of yuan, and even tens of thousands to more than 100,000 yuan. This is much less difficult than making a living on the street. Most importantly, home-invasion burglary is not restricted by the gangs on the street—what criminals hate most is people who don't follow the rules. Thieves who commit home-invasion burglary are also afraid of being stolen, robbed, and killed by others.

Lei Xin continued to talk about the case: "This batch of people mainly obtains information through moving. For example, how many people are in the family, what the environment in the residence is like, where valuables are placed, whether there is a safe, whether there is a jewelry box, and even some families have secret compartments in their wardrobes or somewhere. They can understand these when moving."

"Sometimes they also steal keys, and even steal keys directly. For those with particularly high floors, it is inconvenient to climb, and they look rich. Ordinary thieves can't steal them, but they are easy to steal."

"Moreover, most families are very messy when moving. Some lose things and don't find out for a long time, and some don't even know they have been stolen."

Lei Xin summarized and said: "Basically, it is also a mode of passing on, helping, and leading. At the beginning, one person did it, then pulled accomplices together, and later, there were former prison friends who were released from prison who came directly to do it together. We have screened it so far, and this moving company has at least 6 people who are not clean. Now they are all being interrogated separately, and they shouldn't be able to run away."

Liu Jinghui understood as soon as he heard it and asked: "Did the boss participate?"

Lei Xin shook his head and said: "No. But from the interrogation situation, he at least knows something. It's not certain whether it counts as harboring."

"The boss has a fixed income and doesn't want to do this, but he can't handle these people, so it dragged on." Liu Jinghui confirmed his speculation to Lei Xin and added: "I have worked on similar cases before. The employees in the company colluded, and the boss was afraid of wolves and tigers, didn't dare to call the police, and couldn't handle the other party, and finally they were all wiped out."

"This batch of people is not necessarily clean. It's impossible for the boss not to know when recruiting." Lei Xin paused and added: "The problem now is still evidence..."

Lei Xin looked at Jiang Yuan with hope.

The key to this case is that there is only indirect evidence, no direct evidence. The so-called direct evidence is evidence that does not require other evidence to corroborate and can directly prove the main facts of the case, such as fingerprints at the scene, DNA at the scene, etc.

Indirect evidence requires other evidence to corroborate or requires inference. For example, the police now have a video of the killer buying the same machete at a hardware store, but this video is still indirect evidence. It cannot prove that this person committed the home-invasion murder just because one person bought the same machete.

Of course, it is no problem for the police to exclude the suspicion of other machete buyers, increase the suspect's suspicion, and combine other evidence to infer that the suspect is the perpetrator of the case. It is enough to be submitted for inspection for a home-invasion burglary case, but a death penalty case cannot be so sloppy.

Jiang Yuan felt a rare pressure.

It has been seven days since the case occurred. Although it is not a cold case, much of the evidence no longer exists.

Jiang Yuan re-examined his skills, looked at Lei Xin, and said: "Find the murder weapon."

This answer was not far from what Lei Xin guessed, and it made Lei Xin's mouth bitter.

"How to find it?" Lei Xin asked in a low voice.

Jiang Yuan and Liu Jinghui looked at each other.

A strong sense of powerlessness suddenly arose in Lei Xin's heart, just like waking up on a Saturday morning and seeing his wife's gentle smile...

"Don't worry, don't look for Xu Taining." Jiang Yuan comforted Lei Xin and said: "Division Chief Xu can't run over just to find evidence, and there is no need to look for Division Chief Xu. There are no rivers around the residential area where the victim is located, all the way to the suspect's residence. The suspect hasn't taken a shower yet. Under normal circumstances, he should return home as quickly as possible. As for the murder weapon, it is very likely to be discarded near the scene, or..."

"Trash can?" Lei Xin finished what Jiang Yuan hadn't finished.

If the murder weapon is discarded, in most cases, it is discarded at the scene. Because there are few cases of using guns in China, and whether it is a blunt instrument or a sharp instrument, the smell is not good after being stained with blood or meat mud, and it is not easy to put it away, and it is easy to leave evidence in other places.

Therefore, regardless of whether the killer is experienced or not, voluntarily or forced, they either take the murder weapon away directly, or discard the murder weapon at the scene, or discard it near the crime scene. Few people will take it far away to discard it.

And the trash can mentioned by Lei Xin is even more practical, belonging to the technique that only veterans know.

If ordinary people pay attention to criminal cases in society, they often see in the news that the police found the murder weapon in the trash can. When some people discuss it with each other, they will say that the killer is really stupid. How could they throw the murder weapon into the trash can? Isn't it easy to find?

In fact, throwing it into the trash can is the plan with the highest escape probability.

First of all, the police will not check the trash can every time they encounter a case. In fact, there are few cases of actively looking for the murder weapon. Most of the time, it is after the interrogation results are obtained, and then they look for it according to the suspect's confession.

Secondly, cases are not always discovered in the first place, and as long as it is delayed for a day or two, the murder weapon will leave the trash can and go to another more mysterious and complex place...

Finally, if the killer does not discard the murder weapon in the trash can, but only discards it at the scene, under normal circumstances, no one will help you change the place. As long as the police want to find it, there is always a probability of finding it.

In summary, the source of Lei Xin's fear is exactly that more mysterious and complex place—the garbage mountain.

Based on the philosophy that whoever proposes it is responsible, Lei Xin sighed heavily: "Okay, I will organize manpower to go to the garbage mountain."

"We will check the scene." Jiang Yuan bravely accepted the other half of the task.

That day, Lei Xin set off with more than a dozen young criminal police officers.

Early the next morning, another team of more than 20 criminal police officers, after mobilization, stepped onto the garbage mountain in the suburbs with sadness and heroism.

Jiang Yuan and others took Da Zhuang, Er Zhuang, and the police dogs supported by the Qinghe City Bureau, and searched circle by circle along the residential area.

The murder weapon that killed someone has a very strong smell, and trained dogs can easily smell the bloody smell.

The fact is also true. At noon on the third day, that is, four hours after the third group of criminal police officers stepped onto the garbage mountain, a stylish man walked into the police station near Shuxiang Mingyuan.

"I want to report a case." The man walked to the reception desk.

"What's the situation?" The police officer looked up and sized up the man. Seeing that his expression was calm, he also calmed down.

"I was walking my dog in the morning. My dog kept barking at the bottom of the tree. It had been barking for two days. I was wondering what was going on, so I turned it over, and found a knife, broken, with blood on it." As the man spoke, he lifted a plastic bag onto the counter.

A thick-backed machete broken into two pieces looked familiar.

The eyes of the police officer who received the report became more and more serious, and soon became intriguing.

"Wait a moment, I'll take a statement for you immediately." The police officer took out his mobile phone.

"Ah, do I still need to take a statement?" The stylish man hesitated a little.

"It will be very fast, you don't have to worry, what is your name?"

"Um... Wang Kejiang." The man said his name, and had no other thoughts, obediently led the dog, and sat on the chair next to him.

The police officer who received the report immediately dialed the phone and said: "Director, didn't you say today that you want to draw people to pick up garbage? I found something here..."
