"You've seen that, too. But that didn't make you think of putting an end to the mistake in time, but rather gave you the idea to come up with a near-perfect solution. ”

"You deliberately created and used Wang Yuange's physical and mental pressure, combined with his psychological pressure, to amplify his negative emotions, and then instigated him to commit suicide step by step, and in order to alleviate his pain in the process of suicide, you also took the initiative to illegally purchase a large amount of triazolam for him."

Triazolam is a type of sleeping pill. The plot that you can commit suicide by swallowing a large amount of sleeping pills is purely a fabrication of various film and television novels.

The original sleeping pills, overdose, can indeed cause death.

At the beginning of the 20th century, the first generation of sedative-hypnotic drugs was born, mainly barbiturates, which are derivatives of barbiturates. However, the safety is low, and there are many side effects of overdose, including inhibition of breathing, muscle weakness, and even respiratory failure and shock leading to death. The famous movie star Marilyn Monroe died after taking a large amount of these sleeping pills.

In the late 50s and early 60s of the 20th century, the second generation of sedative-hypnotic drugs was born, mainly benzodiazepines (BZ), which can be divided into short-acting, intermediate-acting and long-acting according to the half-life of the drug. At the same time, it has the advantages of high selectivity, large safety range, and large doses do not cause anesthesia, so it is widely used in clinical treatment.

The representative of short-acting benzodiazepines is triazolam, which can be achieved by adults taking a small amount at a time, and overdose can make people faint for about 10 minutes for 4-6 hours.

But it is too difficult to rely on taking benzodiazepines to commit suicide. To put it simply, taking triazolam as an example, it is difficult to achieve the goal of suicide even if you eat hiccups, and the greatest possibility is to produce the effect of drugs, making the user fluttering, and then falling asleep, or being taken to the hospital for gastric lavage.

In the 80s of the 20th century, the third generation of sedative-hypnotic drugs was born, mainly non-benzodiazepines. Compared with benzodiazepines, there are fewer adverse effects. It also means more safety.

Therefore, Wang Yuange can only use sleeping pills such as triazolam to stun himself, and then hang himself on a rope before he falls into a coma to complete the hanging, so as to reduce the pain in the process of hanging.

"After the fact, you deliberately guide the focus of public opinion. Wang Yuange chose to commit suicide because he couldn't adapt to the role change, and he couldn't wear such a high hat as righteousness and courage, indifferent to fame and fortune, and tenacious resistance to AIDS. After Wang Yuan'e died, there were many voices outside, but the biggest sound was this. Isn't that what you want, what you deliberately lead? ”

In the end, Ma Hongwen said with a slight mockery: "Killing a thousand enemies and losing eight hundred is better than a defeat." As long as the fact that Wang Yuan'e, the 'anti-AIDS fighter' Xibei goods, can be covered up in the past, and suffer a little innocuous loss of reputation, what is it? ”

Ma Hongwen talked nonsense in a serious and emotional manner, with the purpose of intimidating Zhang Pei.

Zhang Pei shook his head again and again while listening, and the anxious and panicked look on his face became more and more obvious as Ma Hongwen's nonsense gradually deepened.

"I'm not...... I didn't...... It's not what you say. ”

As soon as Ma Hongwen's words ended, Zhang Pei couldn't wait to defend himself:

"Wang Yuange said that he had a friend who was addicted to drugs and wanted to help his friend get off drugs, but he didn't want to send him to a drug rehabilitation center, let alone see his friend very uncomfortable when he was addicted, so he asked me what I could do."

"This kind of thing, how dare I make an idea, just say I don't know. Besides, I really don't know. As a result, he said that he was going to buy drugs for his friend, and that by gradually reducing the amount of drugs, he should be able to help him quit drugs, just like quitting smoking. ”

"I was stupefied. Wang Yuan'e ran home from the hospital every night to sleep, which already frightened me. If you still go to help someone buy drugs, if someone finds out his identity, then you might as well kill me directly. ”

"At that time, I also wondered if Wang Yuange was addicted to drugs, and during the hospitalization, because he was watched too closely, he cut off the source of drugs, so he lied to me to get drugs for him. But the hospital gave him a full medical examination and was able to confirm that he was not taking drugs. Therefore what he said to him was believed. ”

"I advised him not to mess around and think of something else. But we couldn't think about it better, and he said it was better to buy some drugs. ”

"As soon as I heard him say this, I was nervous, and in a hurry, I thought that the hospital had said that triazolam overdose would have the effect of drugs. I was in a hurry to go to the doctor, so I gave him this bad idea. ”

When he heard it, he was overjoyed, saying that he didn't think of such a simple solution, and said that taking more triazolam can make people sleep, and when his friend is addicted to drugs, he just needs to let him take more triazolam, which is much better than gradually reducing the dose of drugs. Then, he offered to go to a drug dealer to buy triazolam. ”

Speaking of this, Zhang Pei cried with a sad face: "Comrade policeman, Wang Yuan'e is too capable of tossing." He said he went to the drug dealer, didn't he just force me to go to the drug dealer? What can I do, I can only do what he wants. ”

"Thinking about it now, Wang Yuange should have planned suicide a long time ago. He deliberately led me to come up with a way to overdose on triazolam to help with drug rehabilitation, but it ended up being an excuse for me to help him buy triazolam illegally. I want to know that he wanted an overdose of triazolam to hang himself, and I won't do anything for him. ”

There is no doubt that Ma Hongwen's intimidation played a role.

In order to clear his suspicion of murdering Wang Yuange, Zhang Pei explained the reasons and small details of the illegal purchase of triazolam. At this point, he finally answered the core question of Ma Hongwen's previous question.

It seems that Zhang Pei is not the "master of crime" imagined by Ma Hongwen.

In this regard, Ma Hongwen did not have emotional fluctuations. There is neither the excitement of successfully prying more detailed clues, nor the loneliness of finding an opponent in the interrogation.

Ma Hongwen looked grim and continued to ask: "Triazolam is a drug that is strongly controlled, and generally speaking, it is difficult for individuals to obtain. You have a serious job and a decent life, why did you know the 'professor' who sells drugs? ”

During the investigation into the source of triazolam, no records of browsing illegal websites or illegal online purchases of triazolam were found on Wang Yuan'e's mobile phone and computer.

Ma Hongwen immediately focused his investigation on drug dealers in the city. Overnight, the black market for drugs in Yancheng was turned upside down, and many drug dealers were arrested, including the "professor" known as the "king of medicine" in Yancheng.

No one could have imagined that the pharmaceutical market in Yancheng would be purified in a short period of time in this way.

The "professor" is a woman with a primary school diploma, and unlike other "medical representatives" who go in and out of hospitals and pharmacies to sell drugs, she only pastes and writes small advertisements in hidden corners of the city, which the masses of people often see in the bathrooms of stations, Internet cafes, etc., with the word "drug" written on it and a string of phone numbers written below.

But the "professor" is fashionably dressed, has a good image and temperament, and talks decently, and looks like an intellectual woman, which is very different from the obscene image of secretly selling drugs in the imagination. This should also be another reason why she was given the "honorary title" of "professor".

After the "professor" was arrested, it was not that she was unwilling to cooperate with the police's investigation and questioning, but the buyers who asked her to buy the drugs were all strangers, and even completed the transaction without meeting each other. Therefore, she also "can't tell" who has recently asked her to buy triazolam.

However, Ma Hongwen's people soon found a familiar figure in the monitoring equipment she specially installed for the "den", which was Zhang Pei.

Zhang Pei's appearance surprised the police, but after careful consideration, he was the closest person to Wang Yuange, and Wang Yuange did not come forward by himself, but illegally purchased triazolam through Zhang Pei, and this possibility is completely established.

Therefore, during Ma Hongwen's interrogation, the "professor" confessed that Zhang Pei appeared in his "den" and indeed asked her to buy triazolam. In the last questioning and verification, Zhang Pei also confessed to this.

At the same time, the police also found that Zhang Pei appeared more frequently in the surveillance video, far more than once, and had appeared frequently before Wang Yuan'e took triazolam.

Based on this, the police further concluded that Zhang Pei and the "professor" should be acquaintances. But this relationship between them does not seem to have much to do with Wang Yuange's death.

But Ma Hongwen, who is suspicious by nature, quickly figured out a different flavor from this seemingly simple clue:

Wang Yuan'e overdosed on triazolam during the hanging, Zhang Pei helped Wang Yuan'e illegally buy triazolam, and the "professor" who sold triazolam had an acquaintance relationship with Zhang Pei, are these fragmented clues just a coincidence?

If Wang Yuange's "hanging" was deliberately arranged by some people, then what role did the "professor" who was quite skilled in grasping the dosage and efficacy of triazolam play in this?

On the night of Wang Yuange's death, Zhang Pei had a sufficient alibi, but the "professor" had no alibi that night.

Zhang Pei seems to be just playing the role of a triazolam porter between Wang Yuan'e and the "professor", but is it an acquaintance between Wang Yuan'e and the "professor"? Although the "professor" strongly denied this, Ma Hongwen did not believe it at all.

Once the "professor" admits that she knew Wang Yuange, and she can't produce an alibi on the night of Wang Yuange's death, then her suspicion will only be confirmed and increased.

Therefore, Ma Hongwen asked another question that seemed to have nothing to do with the case.

Judging from Ma Hongwen's question, he did not fully trust Zhang Pei's previous confession. He still thinks that if Wang Yuange was killed by him, Zhang Pei must have played an important role.

As far as Ma Hongwen is concerned, in the absence of sufficient "suicide motives", Wang Yuange's death, all the characters related to it are suspected of "committing crimes".
