At this moment, Chen Yan understood Zhao Linmeng's feelings very well.

No one could understand how Zhao Linmeng, who was only 16 years old at the time, felt when facing the death of his father and fiancé.

And because people from the same village and Zhao Linmeng's father who went to work in the coal mines were bribed, no one told her the truth for the next eight years.

Lengjiang County in Hu Province is rich in antimony ore.

But this mine is located deep in the mountains, and the local residents are closed and ignorant.

16-year-old Zhao Linmeng is considered an evil person who killed his father and fiancé.

So until Zhao Linmeng was 24 years old, no one went to Zhao Linmeng's house to propose marriage.

In the end, she can only marry a fool.

Of course, maybe the sky has eyes and retribution is not good.

It was precisely because of the idiot's father who got engaged to Zhao Linmeng that Zhao Linmeng knew how his father and fiancé died.

It is hard to imagine what kind of determination a child who had not gone to school for several years and had been living in the mountains had to make his way out of that ravine and come to Liancheng to find the truth about what happened back then and finally avenge his father.

Regarding black coal kilns, Chen Yan has not been exposed to any cases in this area, but he has heard of them.

In the early years, when black coal mines were prevalent, human life was worthless in front of money.

Black coal kilns have low mining costs, low labor costs, and low safety costs.

Except for necessary excavation equipment, those black-hearted coal bosses basically don’t need to invest much.

Some people even dig coal manually.

Therefore, coal profits at that time were very high.

The profit from one ton of coal is as high as several hundred yuan.

Even in extreme years, the profit from one ton of coal can reach thousands of yuan.

If a small black coal kiln can produce 10,000 tons of coal a day, the profit can reach millions, or even tens of millions.

This is a day's profit.

Of course, most black coal kilns are relatively small.

The daily output is in the hundreds or thousands of tons level.

There are not many coal mines that mine 10,000 tons of coal every day.

However, even so, the profits of these small black coal kilns range from tens to hundreds of thousands.

Tens of thousands per day, hundreds of thousands per day, how much is it per year?

Millions to tens of millions.

Li Fenglin opened coal mines outside the province and accumulated a net worth of several hundred million in just ten years.

This shows how high the profits are here.

And what does a human life mean in the face of such huge interests?

This was already more than ten or twenty years ago.

At that time, relevant supervision was not strict and laws and regulations were not sound.

People's concept of the rule of law is also not deep.

Therefore, for many murders that occurred in black coal mines, no one called the police at all.

Even if someone reports the crime, there is no way to investigate it.

The coal cave has been blocked and the body cannot be found. How can we solve the case?

You know, it's not as simple as a few cubic meters of soil.

That is a cave dwelling that goes tens, hundreds, or even hundreds of meters underground!

Moreover, there is no vertical downward direction in the coal cave, or any regular excavation direction.

Coal is mined wherever coal caves are located, so there are many forked roads underneath most coal caves.

Most people will find nothing when they go in.

And once the coal mine collapses, let alone a few policemen.

Even the specialized excavation teams are helpless.

After leaving the interrogation room, Chen Yan did not go to the interrogation room where Zhao Linmeng's mother and brother were staying.

When Chen Yan was interrogating Zhao Linmeng just now, the interrogation results about Zhao Linmeng's mother and younger brother had been sent to his mobile phone.

Zhao Linmeng's mother was unaware of everything.

Zhao Linmeng's younger brother has some impressions of mailing stibnite ore to Zhao Linmeng four years ago, but he can't remember the specifics.

The two of them came to Liancheng three years ago.

Since then, he has been living with Zhao Linmeng.

Last year, Zhao Linmeng helped his younger brother find a marriage.

Invested in opening a supermarket for her brother.

Zhao Linmeng is actually very smart. The wife she found for his brother is not from Liancheng.

But a girl from the village next to her hometown.

He is average-looking, but virtuous and obedient.

This year I also gave birth to a fat son.

Although Zhao Linmeng's own life is ruined, her brother will have a good life.

Her mother will also be able to rely on her.

As a daughter and a sister, Zhao Linmeng has no regrets in doing this.

In fact, Chen Yan has to say that Zhao Linmeng basically made every case watertight.

Stibnite is harmful to the human body, and only professionals know that.

For example, Chen Yan had never heard of this mineral in his previous life.

Moreover, the side effects caused by this kind of thing are the same as those caused by arsenic poisoning in humans.

It has very strong concealment.

If Chen Yan hadn't solved the previous case, he would have been rewarded with a mineral cognitive map.

Also in the first detective squad, I personally took the bracelet left by Li Fenglin.

I noticed something was wrong with its weight.

Chen Yan was unable to discover the real cause of Li Fenglin's death.

If the problem with the bracelet cannot be discovered, there will be no subsequent process of solving the case.

This case was left over from the past by the First Detective Squadron, so the subsequent work will be handled by the First Detective Squadron.

Because the chain of evidence is relatively complete, Zhao Linmeng has already confessed to her motive and process.

The next step is to prosecute him.

After the verdict is pronounced, the case comes to an end.

However, there is a high probability that Zhao Linmeng will not be sentenced to death.

Although Zhao Linmeng admitted to the first detective squad that she was the one who exchanged Li Fenglin's bracelet.

However, Li Fenglin's direct cause of death was drowning after all.

In the final analysis, there were two reasons why Li Fenglin drowned.

On the one hand, Zhao Linmeng packaged Li Fenglin's bracelet, and the stibnite caused some damage to Li Fenglin's body, causing muscle spasms when he was swimming.

This can lead to drowning.

On the other hand, Li Fenglin was also responsible for his own death.

Judging from the autopsy results, Li Fenglin's body was damaged by stibnite for a long time, about a year.

Li Fenglin himself should have been aware of the damage caused to him by the stibnite during this period.

Such as muscle spasms.

It definitely doesn't happen just once or twice.

Under such circumstances, Li Fenglin often swam.

Therefore, he himself has a certain responsibility for his own death.

Moreover, Zhao Linmeng's repackaging of Li Fenglin's bracelet had a direct impact on poisoning Li Fenglin.

It is true that Zhao Linmeng poisoned Li Fenglin, and he hoped to poison Li Fenglin to death through this method.

However, she did not expect that Li Fenglin would drown due to muscle spasm while swimming.
