Lu Weiwei had already rolled up her sleeves and was ready to hit someone. She called everyone over to play riddles with you, Gao Chuanfeng?
Officer Wang was also a little impatient. He asked Gao Chuanfeng directly: "Xiao Gao, you are a forensic doctor, not a philosopher. We are in a hurry now and don't have time to discuss life with you here, so what do you want to say?"
"I'm thinking about the effects of drugs on depressed patients." Gao Chuanfeng turned back and handed a filled-in test form to Officer Wang.
Officer Wang was stunned, a little confused.
After all, I was an outsider in the drug test marked above. I just wanted to ask Gao Chuanfeng for advice, but Gu Chen got it in his hands.
"Benzodiazepines and barbiturates?" Gu Chen was a little unfamiliar with these two drugs and seemed to have never heard of them.
He glanced at Gao Chuanfeng: "So? What is this?"
"The English name of benzodiazepines is Benzodiazepine, also known as benzodiazepine salts. It is a type of central nervous system depressant."
Like a doctor prescribing medicine, Gao Chuanfeng picked up a pen and started writing on a note: "We often use it as a sedative and hypnotic drug in clinical practice, and it is generally used for the treatment of epilepsy, anxiety and other diseases."
"So, it is a drug that boosts or calms the mind?" Gu Chen asked him.
Gao Chuanfeng nodded slightly: "You can understand it that way, but what I detected in Zhu Huaiping's body were diazepam tablets and alprazolam tablets."
"Why is this name so difficult to pronounce?" Lu Weiwei felt that it was too difficult to remember just hearing the name, let alone understand it.
Gao Chuanfeng is happy to explain...
After all, I am a professional.
"Actually, it's not 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 purposes."
"It can relieve reflex muscle spasms caused by inflammation, etc., and can be used to treat panic disorder, muscle tension headaches, and can also treat familial, senile and essential tremors. When used, it can be used for pre-anesthetic administration."
"Oh, it seems very powerful." Although I didn't quite understand, Gao Chuanfeng's explanation was also very professional, and it was 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 also indicated. They are mainly used for anxiety, tension, and excitement. They can also be used as an auxiliary medication 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 mental depression."
"Should it be used with caution on patients with mental depression?" After hearing this keyword, Lu Weiwei seemed to understand something.
"These two drugs you mentioned are benzodiazepines, right? Then you also mentioned barbiturates, what are these?" Gu Chen also has a blind spot in this knowledge and has never done it before.
Learn more.
But since Gao Chuanfeng can detect it, he must have complete information here.
Gao Chuanfeng suddenly felt proud: "Finally there is something that you, Gu Chen, don't know. What did I think you knew?"
Lu Weiwei gave him a slap on the head: "Gao Chuanfeng, if you know it, just tell me quickly and stop fooling around, okay?"
"Please don't touch my head. I hate people touching my head." Gao Chuanfeng narrowed his eyes.
You can cut your head off, but don’t mess up your hairstyle. This is your life creed.
However, these words were useless to Lu Weiwei. Lu Weiwei slapped his head again: "Hurry up, we are in a hurry."
Gao Chuanfeng: "..."
"Well, you, Lu Weiwei, are the only ones who are awesome." Gao Chuanfeng didn't want to share Lu Weiwei's knowledge, so he added, "To understand barbiturates 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."
"Barbituric acid?" Gu Chen read it thoughtfully.
"Yeah." Gao Chuanfeng nodded slightly and added: "But not long after, two scholars in Berlin, Germany, one named Joseph Van Marin and the other named Amy Fisher, they learned from Barbituric acid
A substance was synthesized, the English name is: Barbital, we can also translate it as barbital."
"It has a sedative and hypnotic effect, and barbiturates were quickly commercialized and widely used as sleeping pills. Due to their good effects, many similar drugs have been synthesized and put on the market one after another, and these drugs are commonly known as barbiturates.
Proper salt.”
"And the phenobarbital and secobarbital I detected in Zhu Huaiping's body also fall into this category."
Gu Chen hissed, crossed his arms and examined himself carefully: "According to your test results, normal people should not take this kind of medicine, especially for patients with depression, then they should not take it, right?
?”
"Yes, it seems that you, Gu Chen, understand very quickly." Gao Chuanfeng grinned.
This was the question he wanted to discuss with Gu Chen.
After all, he needed to let Gu Chen understand the characteristics of the drug so that he could discuss the case in a targeted manner.
In particular, it explores why Zhu Huaiping committed suicide twice.
With this explanation, Gu Chen seemed to be enlightened. He turned to look at Gao Chuanfeng and said, "If we go by 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 notorious for causing depression and aggravating the condition."
"And benzodiazepines, diazepam tablets and alprazolam tablets, as well as barbiturates, phenobarbital and secobarbital all fall into this category."
"As long as a small amount of any kind of medicine is added to the victim's food or drink, one to three times a day, the user will feel tired and exhausted."
This chapter is not finished yet, please click on the next page to continue reading the exciting content! "Both are symptoms of depression, and the dosage can be adjusted according to the user's response."
"So that's it?" Gu Chen suddenly realized and felt that his previous guess was right.
He looked at Gao Chuanfeng and asked: "In this case, will the victim become more depressed? So this type of drug can actually cause symptoms of depression?"
"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 slowly walked to the side.
Gao Chuanfeng also left his seat, followed Gu Chen, pointed to Zhu Huaiping's body and explained: "Maybe there is another way. Some people can also use amphetamines or diet pills, which are also drugs that can boost their spirits."
"And these things may cause depressed victims to experience feelings of panic, restlessness, or anxiety."
"Similarly, these feelings are common in depression, and anxiety is often a component of the depressive syndrome."
"After several weeks of repeated use, the victim will become exhausted, even listless and depressed."
Gu Chen nodded slightly and said in agreement: "It's a good thing that I left it to you to conduct the autopsy, otherwise we might all have been deceived, and this Zhu Huaiping was probably extremely depressed after taking these drugs.
."
"Yes." Gao Chuanfeng also agreed very much. After all, this was also his reflection after the test.
Gao Chuanfeng had been thinking about the impact of these drugs on the deceased Zhu Huaiping.
Obviously, once the causes and consequences are sorted out, the situation immediately becomes clear.
"The good thing is that I found drugs that can boost or calm the mind during the autopsy, because almost all routine drug tests will include them in the detection range."
"We forensic doctors may or may not conduct a drug test, but because you, Gu Chen, emphasized it, and it seems that the deceased Zhu Huaiping did suffer from symptoms of depression, I decided to conduct 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 were left to others, they might not include toxicology tests in the autopsy.
in."
"Don't expect all forensic doctors to be able to cover everything. Those people are much lazier than me."
"Hey? Junior Brother Gu praised you a few times and you still got out of breath? Isn't this what you should do? After all, you, Gao Chuanfeng, are our long-term partners."
Lu Weiwei actually admires Gao Chuanfeng's work attitude. After all, he is Liu Forensic Doctor's apprentice and he is reliable.
Moreover, Gu Chen's tests are usually handed over to Gao Chuanfeng and forensic doctor Liu, so everyone has formed a certain tacit understanding.
Of course, it is not impossible to rule out lazy forensic doctors who do perfunctory tests just for the sake of convenience. This situation is not unheard of.
But in the forensic team led by Forensic Doctor Liu, this situation would never happen, so it was worthy of Gu Chen's trust.
However, after the test, a new question appeared in front of Gu Chen, that is, were the drugs Zhu Huaiping took himself, or were they given to him by others?
Generally speaking, patients with depression often use some drugs secretly behind the backs of their relatives, friends and doctors.
Even if such substances are found in their blood, urine and stomach, it is not noticeable at all, but is expected.
After all, one problem with diagnosing depression is how to confirm whether it is caused by legal or illegal drugs, or whether it is caused by co-occurring conditions, which must all be taken into consideration.
Therefore, the forensic doctor may be able to find the drug, or he may not be able to find it.
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 approached Gu Chen and asked, "Junior Brother Gu, do you think someone could have deliberately given Zhu Huaiping the drugs Gao Chuanfeng mentioned for a long time?"
"Well, there are many possibilities for this." Gu Chen did not draw a conclusion immediately, but expanded the problem and started analysis and discussion with everyone:
"First of all, we have to understand suicide and depression, because many depressed people in the world choose to end their own lives every day, so this is a very common thing."
"People with severe depression often do not have the strength to successfully complete suicide."
"After all, you think, a lot of things have to be planned in advance, right?"
After saying this, seeing everyone nodding frequently, Gu Chen also stretched out his fingers and gestured: "When will this happen? Where? How to do it? Who will find the body? Are the funeral arrangements in place?"
"It's all something that takes time, thought and energy, and the people doing it have to think about it, and they usually don't take the time to do it."
"I understand." Lu Weiwei immediately understood what Gu Chen meant and said directly:
"They usually don't do this, but if you give these patients with severe depression a drug that can bring vitality, then they will suddenly become able to do it, right?"
Gu Chen nodded slightly: "Although I don't want to admit it, this is very sad, but it is also true."
Yuan Shasha suddenly remembered what she heard from the uncle and aunt in the community where Zhu Huaiping lived, so she quickly interrupted:
"I remember those uncles and aunts said that Zhu Huaiping was a positive and sunny person, but in the past few months, he began to 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 that forensic doctor Gao said, which caused his original thoughts of committing suicide to suddenly become stronger?"
The scene suddenly fell silent for a few seconds. Seeing that no one spoke, Yuan Shasha seemed a little embarrassed.
So she asked weakly: "So? Is what I said wrong?"
"No, on the contrary, Xiao Yuan, you are right." Gu Chen finally spoke while thinking, and said calmly: "Zhu Huaiping is also a top student who graduated from graduate school. He will not understand these things. He cannot be depressed when he is depressed.
Edible.”
"Then anyone who knows these things must be a top student. At the very least, he must understand these things, and he must also know Zhu Huaiping's condition."
"Only when these conditions are met can harm be done to Zhu Huaiping."
Having said this, Gu Chen suddenly raised his head and looked at everyone, paused and added: "But there is an important issue involved here. At least if we want to implement this plan in time, short-term use of drugs will not have much effect, and it must be a long-term plan."
project."
"In order to prevent Zhu Huaiping from noticing it and to make him take medicine every day, he must be the person who has the closest contact with him."
"The closest person?"
After hearing Gu Chen's words, everyone couldn't help but think of a name in their minds.
"Wan Yajuan?!"
Lu Weiwei, Officer Wang and Yuan Shasha almost spoke in unison.
"Yes, it's Wan Yajuan." Gu Chen didn't shy away from it and said directly: "Because she is the person closest to Zhu Huaiping, and if there is a chance, there is no one other than her who tampered with his food every day.
can do."
"Is it to get him a divorce?" Officer Wang took a breath and shook his head: "But it doesn't make sense. Even if you want a divorce, you don't need to be ruthless, right?"
"This matter can only be known after investigation." Gu Chen didn't want to do useless analysis now.
In the current situation, the most important thing is to find enough clues for Wan Yajuan to plead guilty.
So Gu Chen said again: "Calculate the names of these medicines and send them to Senior Brother He and ask her to check whether Wan Yajuan has prescribed any medicine in the past few months."
"Yes, she should be investigated carefully, 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 that before, Junior Brother Gu? After Zhu Huaiping fell to his death, Wan Yajuan's attitude seemed to have become tougher and she refused the autopsy. Maybe Han Dewen's guidance was behind this.
Advice.”
"After all, if anything is really detected, it will definitely be detrimental to her, Wan Yajuan."
What Lu Weiwei said made sense. This was what Gu Chen had thought before.
Now it seems that Wan Yajuan is indeed not simple.
He has an unclear relationship with Han Dewen, and the problem can be seen from the fact that he carries a bag worth nearly 50,000 yuan.
He also refused an autopsy and had a tough attitude, which was a bit abnormal.
Under normal circumstances, most relatives would be willing to perform an autopsy. After all, why did Zhu Huaiping suddenly become extreme and even have strong thoughts of committing suicide?
This change must not be a sudden one.
The serious injuries caused to people have also become a public and social issue. Without a clear investigation, it will be difficult to give an explanation to the families of the injured.
After the corpse examination, things that were beneficial to the deceased Zhu Huaiping were strongly opposed by Wan Yajuan, who was about to divorce, which inevitably made people suspicious.
Forensic assistant Gao Chuanfeng suggested: "You can contact your colleagues and first investigate whether his wife has purchased these drugs. On my side, I have to sort out these test substances, which will probably take some time."
"How long will it take?" Gu Chen asked him directly.
"At least it can be done before dinner. I think it's getting late. You have to comfort Zhu Huaiping's parents. Why not just have dinner in our city bureau cafeteria and wait for your colleague He Junchao to figure out the situation.
You go find Wan Yajuan again, and I will produce this detailed autopsy report. If the evidence is conclusive, you will not believe that Wan Yajuan has not pleaded guilty."
"Okay." Gu Chen really needs a detailed autopsy report now, and combined with the things collected by He Junchao, he can finally find other clues and bring Wan Yajuan to justice.
He knew there was something wrong with Wan Yajuan, but he couldn't touch her yet. He could only take it slow first, and after thinking about it, he agreed.
"Then Xiao Yuan and I are going to accompany Zhu Huaiping's parents?" Lu Weiwei couldn't help but ask when she saw the old couple sitting at the door looking very pitiful.
Gu Chen nodded silently: "Then you go, senior brother Wang and I will stay here to help Gao Chuanfeng complete the report."
"OK."
"That `s a deal."
Everyone had a clear division of labor. Gu Chen and Officer Wang helped Gao Chuanfeng, Lu Weiwei and Yuan Shasha comfort Zhu Huaiping's parents.
Unconsciously, everyone was so busy that they got off work in the afternoon.
Gao Chuanfeng twisted his neck and buttocks, stretched 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."
"It's too sloppy. He Junchao has become a dragster again." Officer Wang thought about it, quickly took out his mobile phone and said: "I have to make a call to urge him, otherwise this guy will go to the cafeteria to eat, and we will have to waste a lot of time.
Yes, for convenience, I will order a meal for him later."
