National Forensic Doctor

Criminal Police Brigade.

Lei Xin urgently sorted out the recent burglary cases and invited Zhu Tianwei's colleagues back to assist in the investigation.

When Jiang Yuan returned from the on-site investigation, Lei Xin identified all the suspects.

"It's not troublesome, they are basically ex-convicts." Lei Xin sighed and repeated the old saying: "The security situation in Qinghe City is very serious. These people used to eat with Jianyuan, and their income was suddenly cut off. If nothing else, some people start engaging in traditional crimes."

"They are just too lazy to work. It is too comfortable to eat with Jianyuan, but ordinary people do not always work honestly. Even if being a porter is very hard and the income is not high, it is not that they steal from others. Reasons to eat other people." Liu Jinghui, who is in his forties, still seems too indignant when he talks about this.

As the captain of the criminal police brigade, Lei Xin was no longer so cynical, and he couldn't be like Liu Jinghui, who could scold whatever he wanted. He still could only shake his head and said: "I'm not excusing them, but the reality is really complicated. What I actually want to say is that our current situation in Qinghe really requires Team Jiang to be in charge."

He made the request jokingly, a bit of a half-truth test.

Jiang Yuan was flipping through the files. He raised his head and said, "I'm planning to stay a few more days. Captain Lei, just don't find us annoying."

Ningtai County is affiliated to Qinghe City. Although the Ningtai County Bureau and the Qianjin District Bureau are said to be on the same level, the Qinghe City Bureau is the superior unit of the Ningtai County Bureau and also has the power to provide business guidance to 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 Municipal Bureau, but it is mainly beneficial to Ningtai County. The Qinghe Municipal Bureau has cooperated very well.

Seeing that the security environment in Qinghe City has changed, the Ningtai County Bureau should still help as much as possible if it is able to help. Not to mention that criminals in Qinghe City will roam around and easily create a criminal environment. There is no need to wait for the Qinghe City Bureau to issue an order.

Lei Xin was doubly surprised and said hurriedly: "Really? Oh, this is great. If you say that, we will feel relieved..."

"The cases have to be carried out one by one." Jiang Yuan smiled and said: "Zhu Tianwei's case is mainly about evidence collection. Let's handle his case first and look at it later. Well, we can take this case along the way. Let’s do a bunch of burglaries.”

"Breaking into a house should not be taken lightly. It is basically an advanced crime." Liu Jinghui said.

Burglary involves entering the residence of the person being stolen from, which is much more risky than stealing outdoors or on a bus. In addition, thieves must learn at least one of the skills of lock picking and wall climbing. Just this learning alone The cost is beyond the reach of brothers who are new to the theft industry.

At the same time, the criminal experience and courage required for burglary are also quite large. It is very easy for a burglary to turn into a burglary, a burglary or even a murder. Because of this, the criminal law's crackdown on burglaries is much stronger than ordinary thefts.

Therefore, burglary is an advanced crime, and it is an advanced direction chosen by young Karami who have entered the world.

The effect of this advanced path is also very significant. First of all, the income is relatively high. A break-in can cost as little as hundreds or thousands of dollars, as much as tens of thousands of dollars or even hundreds of thousands of dollars. This is much less difficult than making a living on the street. The most important thing is that burglary is not very restricted by the evil forces on the street - what criminals hate most are unruly people and burglars. I am also afraid of being stolen, robbed, or killed.

Lei Xin went on to talk about the case and said: "This group of people mainly obtained information through moving, such as how many people are in the family, what the environment is like in the house, where the valuables are placed, and whether there is a safe. Whether there is a jewelry box or even a hidden compartment in someone’s wardrobe or somewhere, you can know when you move.”

"Sometimes they even steal the keys, or even steal the keys directly. The floors are very high and it's inconvenient to climb the stairs. Also, they seem to be rich. Ordinary thieves can't steal them, so they're the only ones who can do it. steal."

"Moreover, most people are very messy when they move. Some people lose things and cannot find them for a long time. Some even don't know that they have been stolen."

Lei Xin summed it up and said: "Basically, it's a mentoring model. At the beginning, one person did it, and then he brought his accomplices together. Later, some former inmates who had been released from prison came directly. Let’s do it together. We have screened out and found that at least 6 people in this moving company are unclean. They are all being reviewed separately now, so they shouldn’t be able to escape.”

Liu Jinghui understood it as soon as he heard it and asked: "Is the boss involved?"

Lei Xin shook his head and said, "No. But judging from the interrogation, he at least knew something about the situation. Whether it counts as harboring or not, I'm not sure yet."

"The boss has a fixed income and is unwilling to engage in this kind of thing, but he can't handle these people, so he just drags him down." Liu Jinghui confirmed his guess to Lei Xin, and then said: "I have done similar cases before. The employees within the company colluded, and the boss was afraid of wolves and tigers, so he didn’t dare to call the police, and he couldn’t defeat the other party, so he was eventually blamed.”

"This group of people is not necessarily clean. With so many ex-convicts, it's impossible for the boss not to know about it when he recruits people." Lei Xin paused for a moment and then said: "The problem now is still the evidence..."

Lei Xin looked at Jiang Yuan hopefully.

The key to this case is that there is only indirect evidence and no direct evidence. The so-called direct evidence means that it can directly prove the main facts of the case without the need for other evidence, such as fingerprints at the scene, DNA at the scene, etc.

Indirect evidence requires other evidence to support or inferences. For example, the police now have a video of the murderer buying the same machete at a hardware store, but this video is still indirect evidence. It cannot prove that a person committed the crime of extermination just because he bought the same machete.

Of course, the police increased the suspicion of the suspect by excluding the suspicion of several other machete purchasers. Combined with other evidence, it is no problem to infer that the suspect is the perpetrator of this case. It is enough to switch to a burglary case for prosecution, but a death penalty case is It can't be so careless.

Jiang Yuan rarely felt a burst of pressure.

It has been seven days since the crime occurred. Although it is not a backlog of cases, a lot of evidence no longer exists.

Jiang Yuan re-examined his skills, then looked at Lei Xin and said, "Look for the murder weapon."

This answer was not far from what Lei Xin guessed, and it made Lei Xin feel bitter in his mouth.

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

Jiang Yuan and Liu Jinghui looked at each other.

Lei Xin suddenly felt a strong sense of powerlessness in his heart, just like when he finally woke up on Saturday morning and saw his wife's gentle smiling face...

"Don't worry, we're not looking for Xu Taining." Jiang Yuan comforted Lei Xin and said, "It's impossible for Xu Chu to come here simply to find evidence, and there's no need to look for Xu Chu. There are no rivers around the community 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 go home as quickly as possible. If the murder weapon was found, it would probably be abandoned near the scene, or..."

"Trash can?" Lei Xin finished what Jiang Yuan had not finished.

If the murder weapon was discarded, in most cases it was discarded at the scene. This is because guns are rarely used to commit crimes in China, and whether it is a blunt or sharp weapon, if it is stained with blood or meat, it will smell bad and is difficult to store, so it is easy to leave evidence elsewhere.

Therefore, no matter whether the murderer is experienced or not, whether actively or under compulsion, he or she will take away the murder weapon directly, discard the murder weapon at the scene, or leave it near the crime scene. Very few people will take it all the way to discard it.

The trash can that Lei Xin mentioned is more practical and is a skill that only veterans can understand.

If ordinary people pay attention to criminal cases in society, they will often see in the news that the police found the murder weapon from the trash can. When some people discuss with each other, they will also say that the murderer is really stupid, how could he use the murder weapon? If you throw it into the trash can, you won't find it as soon as you look for it.

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

First of all, the police will not go through the trash can every time they encounter a case. In fact, there are very few cases where they are looking for the murder weapon. Most of the time, they will search it based on the suspect's explanation after the interrogation results are obtained.

Secondly, the case is not always discovered immediately, 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 complicated place...

Finally, if the murderer did not discard the murder weapon in the trash can, but just discarded it at the scene, under normal circumstances, no one would help you change the location. As long as the police want to look for it, there is always a probability of finding it.

To sum up, the source of Lei Xin's fear is the more mysterious and complex place - the garbage mountain.

In line with the concept of whoever proposes it is responsible, Lei Xin sighed heavily: "Okay, I will organize people to dig through the garbage mountain."

"Let's go check the scene." Jiang Yuan accepted the other half of the task bravely.

That day, Lei Xin set out with a dozen young criminal policemen.

Early the next morning, another team of more than 20 criminal policemen, after mobilization, marched tragically onto the garbage mountain on the outskirts of the city.

Jiang Yuan and others took Dazhuang, Erzhuang and the police dogs supported by the Qinghe Municipal Bureau to search in circles along the community.

The weapons that have killed people have a strong smell, and a trained dog can easily smell the smell of blood.

This is also true. At noon on the third day, four hours after the third group of criminal policemen stepped onto the garbage mountain, a fashionable man walked into the police station near Shuxiang Mingyuan.

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

"What's the situation?" The policeman raised his head and looked at the man. He looked calm and calmed down himself.

"I was walking my dog ​​in the morning, and my dog ​​kept barking at the bottom of the tree for two days. I looked around to see what was going on, and found a knife. It was broken and there was blood on it," the man said. During this time, he slipped a plastic bag onto the countertop.

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

The eyes of the policeman who responded to the call became more and more solemn, and soon became intriguing again.

"Wait a moment, I'll make a note for you right away." The policeman took out his mobile phone.

"Ah, you still need to take notes?" The fashionable man hesitated.

"It'll be quick. Don't worry. What's your name?"

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

The policeman who received the call immediately dialed the phone and said: "Director, didn't you say you would send people to pick up garbage today? I have something here..."
