I am a super cop

Chapter 916 Benzodiazepines and barbiturates
Lu Weiwei has already rolled up her sleeves and is ready to hit someone, and she called everyone over together, just to play riddles with you, Gao Chuanfeng?

Officer Wang was also a little impatient, and he asked Gao Chuanfeng directly: "Xiao Gao, you are a forensic doctor, not a philosopher. We are in a hurry now, and we don't have time to discuss life with you here, so what do you want to say?"

"I'm thinking about the impact of drugs on depressed patients." Gao Chuanfeng turned around and gave a completed test form to Police Officer Wang.

Officer Wang was stunned for a moment, unable to understand.

After all, I am a layman for the drug test marked above. I just wanted to ask Gao Chuanfeng for advice, but Gu Chen took it.

"Benzodiazepines and barbiturates?" Gu Chen was a little unfamiliar with these two drugs, as if he had never heard of them.

He glanced at Gao Chuanfeng: "So? What is this?"

"The English name of benzodiazepines is Benzodiazepine, also known as benzenediazonium salt, which is a kind of central nervous system depressant."

Like a doctor prescribing medicine, Gao Chuanfeng picked up a writing pen and wrote on a sticky note: "We often use it as a sedative and hypnotic drug clinically, and it is generally used for the treatment of epilepsy and anxiety."

"So, it belongs to boosting or calming drugs?" Gu Chen asked him.

Gao Chuanfeng nodded slightly: "It can be understood in this way, but what I detected in Zhu Huaiping's body were diazepam tablets and alprazolam tablets."

"Why is this name so awkward?" Lu Weiwei felt that it was too difficult to remember the name, let alone understand it.

Gao Chuanfeng is more than happy to explain...

After all, I am a professional.

"Actually, there is nothing difficult to understand. You just need to remember that diazepam tablets are mainly used for anxiety, sedation and hypnosis, and can also be used for anti-epileptic and anti-convulsant."

"It can relieve reflex muscle spasms caused by inflammation, etc., and can be used to treat panic attacks, muscle tension headaches, and even familial, senile, and essential tremors. When used, it can be used for pre-anesthesia administration."

"Oh, it seems very powerful." Although I don't understand it well, Gao Chuanfeng's explanation is also very professional, and it is necessary to pretend to cooperate with him.

So Lu Weiwei asked again: "Then what the hell is this alprazolam tablet?"

Gao Chuanfeng said: "Alprazolam tablets are actually an indication for anxiety, tension, excitement, and can also be used as an adjuvant drug for hypnosis or anxiety."

"However, it can also be used as an anti-panic drug and can relieve acute alcohol withdrawal symptoms, but it should be used with caution in patients with psychotic depression."

"Should it be used with caution in patients with mental depression?" Hearing this key word, Lu Weiwei seemed to understand something.

"The two you mentioned are both benzodiazepines, right? Then you mentioned the barbiturate salt, what is it?" Gu Chen is also blind to this knowledge, and has never done it before. Learn more.

But since Gao Chuanfeng can detect it, presumably his information here should be complete.

Gao Chuanfeng was immediately proud: "Finally, there is something you, Gu Chen, don't know. I thought you knew it?"

Lu Weiwei gave him a slap on the head: "Gao Chuanfeng, if you know it, you should hurry up and say it, can you stop being so stupid here?"

"Please don't touch my head, I hate it when people touch my head." Gao Chuanfeng narrowed his eyes.

The head can be broken, and the hairstyle cannot be messed up. This is my life creed.

However, these words are useless to Lu Weiwei, Lu Weiwei poked his head again: "Hurry up, we are in a hurry."

Gao Chuanfeng: "..."

"Well, you, Lu Weiwei, are awesome." Gao Chuanfeng didn't want to be as knowledgeable as Lu Weiwei, so he said again: "To understand barbiturate salt accurately, you must first understand its history."

"That is, in 1864, there was a man named Adolf van Bayer. He mixed malonic acid and urea, and after the interaction, a new chemical substance was produced. Adolf named it Barbituric acid. acid."

"Barbituric acid?" Gu Chen read it along, thoughtfully.

"Well." Gao Chuanfeng nodded slightly, and said again: "But not long after, two scholars in Berlin, Germany, one named Joseph Van Marin and the other named Amy Fisher, found that they were Synthesized a substance, the English name is: Barbital, we can also translate it into Barbital."

"It has the effect of calming and sleeping, and barbiturate was quickly commercialized and widely used as a sleeping pill. Because of its good effect, many similar drugs were also synthesized and marketed one after another. These drugs are commonly known as barbiturates. Proper salt."

"And the phenobarbital and secobarbital I detected in Zhu Huaiping's body also belong to this category."

Gu Chen hissed, crossed his arms and examined himself carefully: "Based on your test results, normal people shouldn't take this kind of medicine, especially for people with depression, so they shouldn't take it, right? ?”

"That's right, it seems that you, Gu Chen, understand very quickly." Gao Chuanfeng grinned.

This is what he wants to discuss with Gu Chen.

After all, he needs to let Gu Chen understand the characteristics of the drug in order to discuss the case in a targeted manner.

Especially to explore why Zhu Huaiping committed suicide twice.

With this explanation, Gu Chen seemed to be a little enlightened. He turned his head and looked at Gao Chuanfeng, and said, "According to your test results, could it be that someone else is using drugs that can boost or calm the mind to achieve their goals? ?”

"It's very possible." Gao Chuanfeng nodded without thinking, and explained: "Because tranquilizers and sedatives are known to cause depression and exacerbate the disease."

"And the benzodiazepines, diazepam tablets and alprazolam tablets, and the barbiturate drugs, phenobarbital and secobarbital, all fall into this category."

"As long as a small amount of any drug is added to the victim's food or drink, one to three times a day, the user will feel tired and tired."

"Both are symptoms of depression, and the dosage can be adjusted according to the response of the user."

"So that's the case?" Gu Chen suddenly realized, feeling that his previous guess was right.

He looked at Gao Chuanfeng and asked: "In this way, will the victim become more depressed? So this type of drug will actually cause depression symptoms?"

"Yes." Gao Chuanfeng said.

The scene fell silent again, and everyone fell into deep thought.

Gu Chen glanced at Zhu Huaiping's body not far away, and walked slowly to the side.

And Gao Chuanfeng also left his seat, followed Gu Chen, pointed to Zhu Huaiping's body and explained: "Or there is another kind, some people can also use amphetamines or diet pills, etc. These are also drugs that can boost the spirit."

"And these things may make the depressed victim feel panic, restlessness, or anxiety."

"Again, these kinds of feelings are common in depression, and anxiety is often part of the depressive syndrome."

"After weeks of repeated use, the victim can become exhausted, even listless and depressed."

Gu Chen nodded slightly, and also agreed: "It's good that I leave it to you for an autopsy, otherwise we might all be deceived, and this Zhu Huaiping is also very likely to be extremely depressed after taking these drugs. .”

"Yes." Gao Chuanfeng also agrees very much, after all, this is also his own reflection after the detection.

Gao Chuanfeng was thinking about the impact of these drugs on the deceased Zhu Huaiping before.

Obviously, once the cause and effect were sorted out, the situation immediately became clear.

"It's a good thing that I found the drugs that can boost or calm the mind during the autopsy, because almost all routine drug tests will include them in the scope of detection."

"As forensic doctors, we may or may not conduct a drug test, but because you, Gu Chen, emphasized it particularly, and it seemed that the deceased Zhu Huaiping was indeed suffering from depression symptoms, so I decided to take a drug test."

Glancing at Gu Chen, Gao Chuanfeng also said with a sense of accomplishment: "It's a good thing you met me, if it was done by other people, they might not include the toxicology test in the autopsy in."

"Don't expect all forensics to be comprehensive, those people are much more lazy than me."

"Yo? Brother Gu praised you a few words and you are still out of breath? Isn't this what you should do? After all, you, Gao Chuanfeng, are our long-term partner."

Lu Weiwei actually admired Gao Chuanfeng's work attitude, after all, he was an apprentice of Forensic Doctor Liu, so he was reliable.

Moreover, Gu Chen's tests are generally handed over to Gao Chuanfeng and Liu Forensic Doctor, so everyone has formed a certain tacit understanding.

Of course, it is not ruled out that lazy forensic doctors are perfunctory when testing for convenience. This is not the case.

But in the forensic team led by forensic doctor Liu, this kind of situation is absolutely impossible, so it is worthy of Gu Chen's trust.

However, after the test, another new question posed in front of Gu Chen, that is, did Zhu Huaiping take the medicine himself, or was it given to him by someone else?
Generally speaking, patients with depression often use some drugs in private behind the backs of relatives, friends and doctors.

Even if such substances were found in their blood, urine and stomach, it would not be noticeable at all, but expected.

After all, one of the problems with diagnosing depression is how to determine whether it is caused by legal or illegal drugs, or whether it is a concurrent condition, and these must definitely be taken into account.

So, forensics may or may not find the drug.

It may be determined that it was artificially imposed on the victim, or it may not be, so Gu Chen must further clarify the truth.

Seeing Gu Chen's hesitation, Lu Weiwei went to Gu Chen's side and asked, "Junior Brother Gu, tell me, could someone deliberately give Zhu Huaiping the drugs that Gao Chuanfeng mentioned for a long time?"

"Well, there are many possibilities for this." Gu Chen didn't make a conclusion right away, but expanded the problem, and started analysis and discussion with everyone:
"First of all, we have to understand suicide and depression because it's a very common thing in the world where many depressed people choose to take their own lives every day."

"People with severe depression often don't have the strength to successfully complete suicide."

"After all, you think, there are a lot of things that have to be planned in advance?"

Speaking of this, seeing everyone nodding frequently, Gu Chen also stretched out his finger and gestured: "When? Where? How to do it? Who will find the body? Is the funeral arranged properly?"

"It's all something that takes time, thought, and energy, and the executors have to figure it out, and they usually don't take the time to do it."

"I understand." Lu Weiwei understood Gu Chen's meaning in seconds, so she said directly:

"They don't usually do that, but if you put a drug that brings vitality to these severely depressed people, suddenly they'll be able to do it, right?"

Gu Chen nodded slightly: "Although I don't want to admit it, it's sad, but it's also true."

Yuan Shasha suddenly remembered what happened in the community where Zhu Huaiping lived, and heard the situation from the uncle and aunt, so she quickly interjected:
"I remember those uncles and aunts said that Zhu Huaiping is a positive and sunny person, but in the past few months, he has become depressed."

"Then can I boldly assume that he has developed symptoms of depression in the past few months due to work or family reasons."

"And during this period of time, someone secretly gave him the drugs Gao Forensic Doctor said, which caused his original suicidal thoughts to suddenly become stronger?"

The scene was suddenly quiet for a few seconds. Seeing that no one spoke, Yuan Shasha looked a little embarrassed.

So she asked weakly again: "So? Am I wrong?"

"No, on the contrary, Xiao Yuan, what you said is quite right." Gu Chen finally spoke in his thoughts, and said calmly: "Zhu Huaiping is also a high-achieving graduate student, he will not understand these things, and he can't when he is depressed. Edible."

"Then a person who knows these things must be a high-achieving student. At the very least, he must understand these things, and he must also know the state of Zhu Huaiping's illness."

"Only when these conditions are met can Zhu Huaiping be harmed."

Speaking of this, Gu Chen suddenly raised his head to look at everyone, paused and added: "But there is an important issue involved here, at least if the plan is to be realised, short-term use of drugs will not have much effect, it must be a long-term project."

"If you want Zhu Huaiping to be unaware, but also let him take medicine every day, it must be the person who has the closest contact with him."

"The closest person?"

Hearing Gu Chen's words, everyone couldn't help thinking of a name in their minds.

"Wan Yajuan?!"

Lu Weiwei, Police Officer Wang and Yuan Shasha almost spoke in unison.

"Yes, it's Wan Yajuan." Gu Chen said without hesitation, "Because she is the person who is closest to Zhu Huaiping, and there is no one else who tampers with his diet every day except her." can do."

"Could it be to get him to divorce?" Officer Wang gasped and shook his head: "But it doesn't make sense. Even if you want to divorce, you don't need to be ruthless, right?"

"This matter can only be known after investigation." Gu Chen doesn't want to do useless analysis now.

In the current situation, the most important thing is to find enough clues to make Wan Yajuan confess her guilt.

So Gu Chen said again: "Calculate the names of these medicines and send them to Senior Brother He to ask her to check whether Wan Yajuan has been prescribed medicine in the past few months."

"Yes, she should check it out, and that Han Dewen." Lu Weiwei glanced at Gu Chen, and said:

"I feel that there must be Han Dewen's guidance behind this. Didn't you say it before, Junior Brother Gu? After Zhu Huaiping fell to his death, Wan Yajuan's attitude seemed to become tougher and she refused the autopsy. Perhaps Han Dewen was behind this." Advise."

"After all, if something is really detected, it will definitely be bad for her, Wan Yajuan."

What Lu Weiwei said makes sense, and this is what Gu Chen thought before.

Looking at it now, Wan Yajuan is indeed not simple.

The relationship with Han Dewen is unclear, and the problem can be seen from the bag of nearly 5 yuan.

Moreover, it is a bit abnormal to refuse an autopsy and have a tough attitude.

Under normal circumstances, most of the relatives are willing to have an autopsy. After all, why did Zhu Huaiping suddenly become violent, and even have a strong idea of ​​committing suicide.

This change must not have been a whim.

The serious injuries caused have also become a public social problem. If the investigation is not clear, it will be difficult to give an explanation to the families of those injured.

After the autopsy, Wan Yajuan, who was about to divorce, strongly opposed the things that were beneficial to the deceased Zhu Huaiping, which inevitably made people suspicious.

Forensic assistant Gao Chuanfeng suggested: "You can contact your colleagues and first investigate whether his wife has bought these drugs. On my side, I have to sort out these test substances. It must take some time."

"How long?" Gu Chen asked him directly.

"At least it can be done before dinner. I think it's getting late, and you have to comfort Zhu Huaiping's parents. Why don't you just have dinner in the cafeteria of our city bureau, and wait for your colleague He Junchao to clarify the situation. You go to Wan Yajuan again, and I will show you this detailed autopsy report, so that the evidence is convincing, so I don't believe that Wan Yajuan pleaded not guilty."

"It's okay." Gu Chen really needs a detailed autopsy report now, and with the things collected by He Junchao, he can finally find other clues and bring Wan Yajuan to justice.

He knew that Wan Yajuan had a problem, but he couldn't touch her yet, so he could only take it easy, thought about it, and agreed.

"Then Xiao Yuan and I are going to accompany Zhu Huaiping's parents?" Lu Weiwei couldn't help asking seeing the old couple sitting at the door looking pitiful.

Gu Chen nodded silently: "Then you go, Senior Brother Wang and I will stay here to help Gao Chuanfeng complete the report."

"Row."

"That `s a deal."

Everyone has a clear division of labor. Officers Gu Chen and Wang helped Gao Chuanfeng, Lu Weiwei and Yuan Shasha comfort Zhu Huaiping's parents.

Everyone was unknowingly busy until the afternoon when they got off work.

Gao Chuanfeng twisted his neck and buttocks, stretched his waist and said: "I will go to the cafeteria to bring you dinner now. I hope your Comrade He Junchao can hurry up, otherwise I think you will have to waste time tonight."

"Damn, it's sloppy, and He Junchao has become an oil bottle again." After thinking about it, Officer Wang quickly took out his mobile phone and said, "I have to make a call to remind him, otherwise we will have to waste a lot of time if this guy goes to the cafeteria to eat." Yes, for convenience, I will order a meal for him later."
