Chapter 99 One wrong step, one wrong step
For Cai Shude to become a doctor, his psychological quality must be excellent, and it is impossible to reveal his flaws in a few words.

From Cai Shude's current performance, He Jiahui can judge that Cai Shude is the kind of criminal suspect who does not cry when he sees the coffin. If he can't produce conclusive evidence, he will definitely not admit his crime.

"Since Mr. Cai wants to see the evidence, I will show you the evidence!" He Jiahui looked at Cai Shude calmly, which made Cai Shude a little guilty.

He Jiahui went on to say: "In this case, the three suspects were directly targeted at the very beginning, so when our police solved the case, we also focused on identifying the suspects, thus ignoring another important point.

That's where the poison comes from!The deceased was injected with an overdose of sedatives. Where did these sedatives come from, but we have not paid attention to them.We also ignore very important clues.

The sedatives that caused the death of the deceased were all controlled drugs, and ordinary people could not buy them. Only qualified doctors could prescribe these sedatives.

And even if a doctor prescribes these tranquilizers, it is impossible for patients to get them, let alone use them privately. They need to be used by professional medical staff in designated medical institutions.

So these tranquilizers come from your hospital.And various tranquilizers are routine therapeutic agents used in oncology departments. As an oncologist, you can prescribe tranquilizers by taking advantage of your position. "

"Hehe, this is the evidence you said? It's ridiculous!" Cai Shude continued with a look of disdain: "I am not the only doctor in our oncology department, we have more than a dozen doctors, and everyone has a prescription for tranquilizers. right.

In addition to our oncology department, there are hundreds of doctors in other departments who have the right to prescribe tranquilizers, and tranquilizers are used in the anesthesia room every day. Why don't you go to them? "

"Because you gave the doctor's order to two patients on the day of the incident, 25 mg of promethazine plus 25 mg of chlorpromazine, intramuscularly injected once. And the police detected the promethazine in the syringe that the deceased killed. zine and chlorpromazine."

He Jiahui paused for a moment, then continued; "You took advantage of your position to prescribe these two tranquilizers to the patient, and when the pharmacy delivered the tranquilizers to the oncology department, you secretly went to the dispensing room to dispense the two tranquilizers. Replace it with normal saline, or other things, and wait until the early morning before you use the tranquilizer you stole to kill the dead!"

"Promethazine and chlorpromazine are both routine therapeutic drugs in our oncology department, which can effectively relieve the physical pain of patients. Every one of our oncologists has prescribed this drug to patients. You can't prescribe it because of me. Two medicines, just insist that I am a murderer!"

Cai Shude smiled slightly, and continued confidently: "What's more, you just said that my patient's doctor's order is 25 mg of promethazine and 25 mg of chlorpromazine. The total of the two patients is only 50 mg. mg promethazine, plus 50 mg chlorpromazine.

This amount of medicine is too small, if it is injected into a person's body, it will not be able to kill a person at all. If it is an adult, it may not even be able to make him incapacitated.

In clinical treatment, for some patients with severe physical pain, a person will use 50 mg of isopropanone plus 50 mg of chloracetone.If you don't believe me, you can go to another doctor to verify it.

Since the dose is not enough to kill, even if your speculation is true, I stole these two tranquilizers and injected them into Dr. Liu's body, but it is still impossible to kill Dr. Liu!

Sir, remember to consult a professional first before drawing conclusions, so as not to reason for a long time, which looks reasonable on the surface, but is actually a joke! "

Facing Cai Shude's ridicule, He Jiahui didn't take it seriously, and he continued; "50 mg of promethazine plus 50 mg of chlorpromazine is indeed not enough to kill an adult, but if you add 50 mg of midazol What about Lun?"

"What midazolam?" Cai Shude immediately put on a look of confusion, but such a quick reaction time confirmed his guilty conscience.

He Jiahui went on to say: "For the average adult, the amount of midazolam injected at one time is at most 15 mg. If it exceeds, it will be dangerous, so the infusion pump is used for 50 mg midazolam.

If there is no infusion pump, 50 mg of midazolam, 50 mg of promethazine, and 50 mg of chlorpromazine are all injected into the human body. Dr. Cai, please tell me with your expertise. Can this be fatal? "

Cai Shude pondered for a moment, and then said: "50 mg of midazolam, 50 mg of promethazine, and 50 mg of chlorpromazine, injected together, will indeed cause danger to life."

He Jiahui immediately said: "In the syringe that killed Dr. Liu, in addition to promethazine and chlorpromazine, midazolam was also detected!"

"Then what does this have to do with me? I didn't prescribe midazolam to the patient!" Cai Shude argued.

"You didn't prescribe midazolam to the patient, but other doctors did. We checked the doctor's order. On the afternoon of the incident, Dr. Wang from your oncology department prescribed 3 mg for the patient in room 50. Midazolam, plus 50 mL of Sodium Chloride Injection, pumped in at a rate of 2 mL per hour.

And that day, you also worked in the afternoon shift, right?That is to say, you and that Dr. Wang work together, and when he writes a doctor's order, you will know immediately, even you are right next to him.

When you saw the doctor's order issued by Dr. Wang for Ward No. 3, you decided to carry out this murder plan, so you also issued promethazine and chlorpromazine wills for patients in other rooms.

Then you secretly replaced the three sedatives with saline.Those real tranquilizers were used by you to kill Dr. Liu, right? "He Jiahui continued.

"Impossible nonsense!" Cai Shude snorted coldly: "Speaking of now, it's just your reasoning, what about the evidence? Didn't you say that there is evidence? You should show the evidence!"

"The police have inspected the infusion pump in Ward 3 and confirmed that there is no midazolam in it, only saline. This is the evidence!" He Jiahui said.

"What kind of evidence is this? I am not in charge of the patient in Ward 3, and I did not issue his doctor's order. The work of drug treatment is done by the nurse. There is no midazolam in the infusion pump. I have What's the matter!" Cai Shude immediately argued.

"With the management level of your hospital, every link in the treatment process will be recorded, and midazolam is a tube-like drug, how could it disappear inexplicably? Unless someone guards and steals it!
And the syringe that killed Dr. Liu happened to contain midazolam, which meant that the midazolam that was supposed to be used by the patients in Ward 3 was used by the guard to kill him! "He Jiahui responded.

"Even so, why do you say that the murderer is me? We also have several doctors in the oncology department. Is it impossible for others to guard against themselves?" Cai Shude asked rhetorically.

"Because when Dr. Liu Guoqiang died, only you were at the scene, and the other doctors were not at the scene! Of course, those who are not at the scene cannot be the murderer." He Jiahui said.

"What about the nurses? Nurses often go to the dispensing room, so it's possible that the nurses are stealing the medicine? That night, besides me, Zhou Yuting and Deng Qiaomei were also there, and they might have stolen the tranquilizers to kill people!
Besides, didn't you already find the key in Zhou Yuting's pocket?This is enough to prove that she committed the crime after killing someone! Cai Shude immediately retorted.

He Jiahui smiled slightly: "Dr. Cai, until now, haven't you realized what the problem is? Let me remind you that the order for 3 mg of midazolam in Ward 50 will be executed at eight o'clock in the evening!"

Cai Shude was stunned for a few seconds, his face changed slightly, obviously he had thought of the key point, but he immediately forced his composure and tried his best to maintain it.

"I really don't cry when I see the coffin, I have to explain everything!" He Jiahui shook his head helplessly, and continued:

"The execution time of the doctor's order in Ward 3 is eight o'clock in the evening, which means that the murderer wants to steal the midazolam in Ward 3 before eight o'clock in the evening, otherwise the drug will be used on the patient. body.

As for the two nurses, Zhou Yuting and Deng Qiaomei, both work night shifts, they arrived at the hospital at 3 o'clock in the evening. At this time, it was already past the time to carry out the doctor's order in Ward 3. It was impossible for them to steal the microphone from Ward [-]. Dazolam!There is no possibility of committing a crime.

Only you, it was the afternoon shift that day, and you stayed in the hospital from afternoon to night. Among the three of you, only you could steal the midazolam from Ward 3!Dr. Cai, what else do you have to say now? "

Cai Shude gritted his teeth, he wanted to continue to argue, but found that he couldn't argue at all.

The execution time of a midazolam doctor's order directly ruled out the possibility of the other two committing crimes, and also locked the murderer on Cai Shude.

Although the key was found on Zhou Yuting before, in the face of the exclusionary law, this kind of evidence can no longer prove that she is suspected. Even if it goes to court, the benefit of the suspicion belongs to the defendant, and Zhou Yuting will not sue.

Just like the classic saying, if you eliminate all the impossible, what remains is the truth no matter how impossible it is!

After being silent for more than half a minute, Cai Shude finally said: "I have no grievances with Liu Guoqiang, why should I kill him!"

"The reason why you killed Dr. Liu should be because of the "Certificate of Medical Exemption", right?" He Jiahui asked.

"Have you even found this out?" Cai Shude's expression changed drastically, and then he slumped down on the chair.

He Jiahui continued: "When we asked Deng Qiaomei before, she once mentioned that the deceased doctor Liu Guoqiang had a conflict with a doctor named Sun Jiacheng, and the reason for the conflict was a scientific research project.

And this doctor Sun Jiacheng has immigrated to the UK now, so there is no possibility of committing the crime, and the police did not investigate him in depth at that time.But just on the way here, I called Dr. Sun Jiacheng.

When he learned that Liu Guoqiang was killed, he immediately guessed that the murderer was probably you, and Dr. Sun Jiacheng also revealed to us your motive for killing Dr. Liu Guoqiang.

According to Dr. Sun Jiacheng's biological narrative, he had a conflict with Dr. Liu Guoqiang at first because of a scientific research project. At that time, both of them were fighting for funds, and the funds provided by the hospital were only enough for one project.

But at the critical moment of funding approval, Dr. Liu Guoqiang found an excuse for Dr. Sun Jiacheng, and he used this excuse to threaten Dr. Sun to give up his scientific research project.And this clue is that Dr. Sun Jiacheng once sold a fake "Certificate of Medical Exemption".

Influenza strikes every winter, and the government has also launched a free influenza vaccination program. However, some citizens have underlying diseases, so they are not suitable for influenza vaccination. At this time, a doctor is required to issue a "Medical Exemption Certificate" ", you can be exempted from vaccination.

And some people don’t want to get vaccinated for various reasons, but if they don’t get vaccinated, it will affect their normal social life and life, so these people go to the doctor to issue a fake “Certificate of Medical Exemption”, so that they don’t need to get the flu vaccine.

This phenomenon has also given birth to many unscrupulous doctors who specially issue fake "Certificates of Medical Exemption". A certificate can be sold for 5000 yuan.If you sell a hundred copies casually, you will get 50 yuan, but for a doctor, this is just a hundred signatures.

Dr. Sun Jiacheng once made such black-hearted money, and after Dr. Liu Guoqiang found out, he became a target to threaten him.It was also for this reason that Dr. Sun Jiacheng immigrated to the UK. He was worried that if he stayed in Xiangjiang, he would be blackmailed by Dr. Liu Guoqiang.

Moreover, there is no extradition treaty between the UK and Xiangjiang. When he went to the UK, Xiangjiang's laws could not sanction him, and the police could not catch him.It is also for this reason that he dared to reveal to us the truth about his emigration to the UK.

At the same time, Dr. Sun Jiacheng also revealed another news. You, Dr. Cai Shude, were the one who issued the fake "Certificate of Medical Exemption", and Dr. Liu Guoqiang also knew about it.

I guess Dr. Liu Guoqiang must have threatened you with this matter, right?That's why you decided to kill Dr. Liu.This is your motive for killing! "

One thing that He Jiahui did not say was that in order to obtain Cai Shude's motive for the murder, he promised Sun Jiacheng that the police would not pursue him for issuing a fake "Medical Exemption Certificate".

After Sun Jiacheng got the promise from the police, he was willing to tell the truth about his immigration to the UK and the fact that Cai Shude issued a fake "Medical Exemption Certificate".

Who would confess to the police about breaking the law if it didn't do any good?

This kind of exchange of conditions is very common in the British and American legal systems, and He Jiahui can be regarded as learning what he has learned and doing as the Romans do.

Issuing a fake "Certificate of Medical Exemption", according to Xiangjiang's "Criminal Offenses Ordinance", is either convicted of fraud or manufacturing false documents.The former is punished according to the amount of money, while the latter can be sentenced to a maximum of 14 years in prison.

At the same time, doctors also violate professional ethics and will be punished by the Medical Council.

The ruin of the future, coupled with 14 years in prison, is indeed enough to make people choose to take risks and choose to kill people to silence them.

Seeing that his motives had been found out by the police, Cai Shude knew that his future was over. At this moment, he finally saw the coffin and no longer chose to carry it to death.

Cai Shude said slowly; "That's right, I did it. I killed Liu Guoqiang! It's all his fault for blackmailing me! Didn't he plan to buy a house and get married? But he couldn't even come up with a down payment!

But it's normal to think about it. This guy usually spends money lavishly, and he also dated two women at the same time. Even if his income as a doctor is relatively high, he can't save much money. "

"So Dr. Liu Guoqiang extorted money from you for issuing a fake "Medical Exemption Certificate"?" He Jiahui asked.

"That's right, he threatened me with the "Certificate of Medical Exemption" and asked me for 300 million, but my house is also paying off the loan. How can I have so much money! When he saw that I couldn't pay, he asked I sold my house to raise money."

Cai Shude showed an excited expression: "I worked so hard to save money to buy that house. For this house, I studied hard, and after becoming a doctor, I worked day and night!
In order to earn a down payment, I even violated the professional ethics of doctors by issuing fake Medical Exemption Certificates.I sacrificed so much to buy the house. This house is the hope of my life and my life. How can I sell it!
Moreover, Liu Guoqiang actually asked me how the properties around my house are. He wants to live near my house, so can he blackmail me often in the future?I can't be blackmailed by him all the time, so I decided to do nothing but kill him! "

Cai Shude took a deep breath as he spoke, and continued: "The method of killing is the same as your reasoning, Sir, I gave him sleeping pills, and when he fell asleep and couldn't resist, I injected him with an excessive amount of tranquilizers.

I put the syringe in Deng Qiaomei's cabinet, and then deliberately told the police about their relationship, and directed the police's investigation to Deng Qiaomei.

Deng Qiaomei did not bring the key to the cabinet. This accident led to the complete bankruptcy of my plan. I could only continue to blame and slip the key of the cabinet into Zhou Yuting's pocket secretly.

Who knew that Zhou Yuting found the key in the pocket, and this stupid woman didn't call the police, but put the key in my pocket, she wanted to set the blame on me.

But I found out that she didn't wear gloves, so she would definitely leave fingerprints on the keys, so I simply played a trick and used the fingerprints on the keys to make the police think that she was the real murderer!
Everything went smoothly, you took Zhou Yuting away, and I thought I was safe, but I didn't expect you to see it through in the end!Sir, how did you come up with the idea to check the infusion pump in Ward 3? "

"Because the family members of the patient in Ward 3 said that his father had been injected with tranquilizers, but it had no effect, so I immediately realized that I should investigate again from the source of the tranquilizers, and then I caught you." He Jiahui did not hide anything .

"I have such a careful plan, but it fell on the patient's family." Cai Shude laughed at himself.

"This has nothing to do with whether the plan is thorough, but that you made a mistake from the beginning!" He Jiahui gave Cai Shude a sympathetic look, and continued:
"In order to make up the down payment for the house, you sold your professional ethics as a doctor and issued a fake "Medical Exemption Certificate" to others. At this first step, you are going wrong.

It is precisely because of this mistake that Liu Guoqiang caught you, blackmailed you, and even forced you to sell the house.The house you obtained by illegal means will eventually be taken away by others by illegal means.

In order to keep your house and not to be blackmailed in the future, you choose to commit a worse crime and kill Liu Guoqiang.In this second step, you are going wrong again.

One wrong step, one wrong step, it's you!If you had adhered to the professional ethics of a doctor and hadn't sold fake "Medical Exemption Certificates", these things would not have happened.

Liu Guoqiang's blackmailing of you is of course his fault, but the root cause of the situation is actually your choice.You chose the wrong path, now, you can only go to Stanley Prison, and use the rest of your life to atone for your sins! "

　Thank you guys for subscribing.As for the motive of the murder, it was written as influenza for the purpose of passing the trial, and the logic was somewhat weakened.This case is over, and the next case has been conceived. It is a more complicated serial murder case. Please allow me to postpone it for a day and ask for leave tomorrow.
