Lu Ling came to Lin Wei this time because he knew enough things, so he had more direction.

Lin Wei is still the same.

"Lin Wei, last time I came here, I saw that you were not in good condition, so I didn't bother you too much. Are you feeling better today?" Yan Yu asked with concern.

"It's better." Lin Wei nodded.

Anyone can see that she has not changed, but last time the police came, they left after caring about her. This time they came again, they still cared about her so much, she had to give her some face.

"We have found out some things, and we are still investigating some things," Lu Ling said. "Li Yun most likely did not commit suicide. His death has nothing to do with you."

Lin Wei's face was full of confusion. She raised her head pitifully and looked at Lu Ling, wondering what Lu Ling meant.

Lu Ling said nothing, giving Lin Wei some time to think.

After a while, Lu Ling said: "In these years, you have been running around for your family. Your brother is also in college. If you have an accident this time, your family will not be able to share the burden for you. Have you considered how to face your own life?

?"

"How can I still have a life..." Lin Wei lowered her head again.

"I've done the math for you," Yan Yu took out an A4 paper with a very detailed form on it, "this is about some compensation plans you can propose after Zhou Ying's family sues you. You can apply not to pay this

If you pay back the interest slowly, you can still pay it back. There is no need to spend your whole life on it. If you do something wrong, you need to bear responsibility. Besides responsibility, it is your own life."

Lin Wei took the paper from Yan Yu with some disbelief. According to some calculations by Yan Yu, she may have to continue to pay compensation for the next ten or twenty years, but this is indeed a way to survive.

...

The communication with Lin Wei was not to obtain any clues. Lin Wei really didn’t know much, but they both felt that although poor people like Lin Wei must be hateful, they are still not bad people.

, can you help me or please help me.

After leaving Lin Wei, Lu Ling received a call from Kou Yuyang.

An important clue was found. Huang Wenying once drove to a pharmacy. The police checked the pharmacy and found that a person from the pharmacy had posted some posts on Tieba. Huang Wenying followed the posts and came to him to buy barium chloride.

At present, the police have found the pharmacy, and the people in the pharmacy admitted to selling barium chloride to Huang Wenying, and Huang Wenying bought 50 grams at a time.

This pharmacy is not qualified to sell some drugs. Although barium chloride is not controlled, the investigation found that he sold far more than barium chloride, so this person was also arrested.

In addition, the police also called the surveillance here and found footage of Huang Wenying purchasing barium chloride.

From the physical evidence point of view, this alone makes Huang Wenying irrevocably suspicious.

This is a big win!

At this time, Huang Wenying had already been taken away.

After Lu Ling and others finished their meeting, Huang Wenying was placed under guard to prevent a long night of nightmares.

However, everything did not go as smoothly as imagined. When Lu Ling saw that the local police issued a search warrant and found 20 grams of barium chloride and a suicide note at Huang Wenying's residence, he knew that the case had collapsed.<

/p>

Obviously, Huang Wenying had enough excuses to buy barium chloride and committed suicide.

There are 10,000 reasons for suicide. If it is not enough, you can make up more.

Now, Huang Wenying used 5 grams of barium chloride to kill people, but she threw away half of the barium chloride. Whether she flushed it into the toilet or threw it into the garbage can no longer be confirmed.

From the search of Huang Wenying's residence, it can be determined that Huang Wenying did purchase barium chloride, but the existing evidence cannot prove that the barium chloride purchased by Huang Wenying has a causal relationship with Li Yun's death!

...

From an evidence point of view, currently, there is no decent evidence at all!

As expected, the local police's first interrogation of Huang Wenying ended in failure.

Huang Wenying said that he was indeed familiar with Li Yun and had heard Li Yun say that he did not want to live anymore. The two even discussed suicide methods. Li Yun said that barium chloride was effective in suicide. So Huang Wenying went to buy some.

, I came back and soaked most of it, but I didn’t dare to drink it, so I threw it away. There was still some left, and I planned to wait until I committed suicide before using it.

Huang Wenying's explanation, although everyone knows that she is talking nonsense, no one can prove that these words are wrong.

The biggest difficulty for Huang Wenying in killing Li Yun was to trick Li Yun into drinking the poison and not making a fuss or seeking medical attention after drinking it. This was the most difficult thing, but apart from that, other things were very, very easy.<

/p>

Now that the case has been investigated, it has come to a standstill. Everyone can only call Li Yun a big idiot, but they don't know how to find enough evidence.

The police can criminally detain Huang Wenying based on existing evidence.

What then?

Like Lin Wei, detained for a few days and then released? This is different from Lin Wei. This is a murderer through and through. If he is released, then where is the dignity of the police?

Such a thing was beyond Lu Ling and Yan Yu's expectations.

"I really underestimated her." Lu Ling sighed.

"Indeed, our investigation from beginning to end was just to find out that she bought barium chloride, but she cracked it directly with such a simple trick." Yan Yu also frowned.

"No wonder she dares to kill people. This backhand is really powerful..." Kou Yuyang held a cut out space bar in his hand and rubbed it, and his thoughts flew to the world.

"I didn't understand a bit..." Qingshan listened for a long time and was confused.

"To put it simply, it is now certain that Huang Wenying bought the poison," Liu Liwen explained, "but it is completely impossible to confirm that Li Yun's death was caused by eating Huang Wenying's poison."

"How could Li Yun die if he didn't eat her poison?" Qingshan was still puzzled.

"This is not the way to analyze problems from the perspective of evidence science." Ye Wenxing shook his head, "Qingshan, I will explain it to you slowly in a moment."

"Captain Yan," Lu Ling said, "So, the question now is, we need to analyze some of Li Yun's behaviors to see if he could leave any traces from the time he took this cup of poison to the time he died?"

"If you think it can be found, why can't you find it now? Now, it seems that there is only one way left, to interrogate Huang Wenying..." Yan Yu said this without any confidence.

And Lu Ling didn't answer this sentence at all.

Interrogation is not a panacea. If all criminals can be identified through interrogation, then the police might as well just learn this subject...

Now that Huang Wenying has come prepared, it is difficult to find a real interrogation expert, let alone Lu Ling.

...

(The case has become more difficult. Does anyone know the direction to solve the case? The first thing that comes to mind is that you can come to the group to receive a hundred yuan red envelope.)

(I have something to do today. I looked at the house all day... There is only one short chapter left. I will try to write more than 6k to make up for it tomorrow...)
Chapter completed!
