If Cai Shude can become a doctor, his psychological quality must be excellent, and it is impossible for Cai Shude to reveal his flaws in a few words.

From Cai Shude's current performance, He Jiahui can tell that Cai Shude is the kind of criminal suspect who will not shed tears until he sees the coffin. If he cannot produce conclusive evidence, he will definitely not admit his crime.

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

He Jiahui continued: "In this case, three suspects were directly identified from the beginning, so when our police solved the case, they also focused on identifying the suspects, thus neglecting another important point.

That's the source of the poison! The deceased died from an overdose of tranquilizers. Where did these tranquilizers come from, but we didn't pay attention to it. We also ignored very important clues.

The tranquilizers that caused the death of the deceased are all controlled drugs and cannot be purchased by ordinary people. Only a qualified doctor can prescribe these tranquilizers.

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

So these sedatives come from your hospital. And various sedatives are conventional treatment drugs used in oncology departments. As an oncologist, you can take advantage of your position to prescribe sedatives."

"Haha, is this the evidence for what you said? How 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 each of them has a prescription for sedatives.

right.

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

"Because on the day of the incident, you gave two patients medical instructions to inject 25 mg of promethazine and 25 mg of chlorpromazine into each other's muscles once. And the police detected promethane in the syringe used by the deceased to kill him.

chlorpromazine and chlorpromazine.”

He Jiahui paused and then said, "You took advantage of your position to prescribe these two tranquilizers to the patient. After the pharmacy sent the tranquilizers to the oncology department, you secretly went to the dispensing room and gave these two tranquilizers to the patient.

Replace it with physiological saline or something else, wait until the early morning, and then use the stolen sedative to kill the deceased!"

"Promethazine and chlorpromazine are both conventional therapeutic drugs in our oncology department, which can effectively relieve patients' physical pain. Each of our oncologists has prescribed this drug to patients. You can't just blame me for prescribing this drug."

Two kinds of medicine, just say that I am a murderer!"

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

mg promethazine, add 50 mg chlorpromazine.

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

In clinical treatment, some patients with severe physical pain will use 50 mg of isopropyl ketone and 50 mg of chloroacetone. If you don’t believe it, you can go to other doctors to verify it.

Since the dose is not fatal, even if your speculation is true and I stole these two tranquillizers and injected them into Dr. Liu's body, it would still not be possible to kill Dr. Liu!

Sir, before drawing conclusions in the future, remember to consult professionals first, so as not to spend a long time reasoning, which may seem reasonable on the surface, but is actually a joke!"

Facing Cai Shude's ridicule, He Jiahui didn't take it seriously. He continued, "50 mg of promethazine and 50 mg of chlorpromazine are indeed not enough to kill an adult. But if 50 mg of midazole is added,

Where’s Lun?”

"What midazolam?" Cai Shude immediately acted as if he didn't know what he was talking about. However, such a quick reaction time confirmed his guilty conscience.

He Jiahui continued: "For ordinary adults, the maximum amount of midazolam injected at one time is 15 mg. If it exceeds, it will be dangerous, so only 50 mg of midazolam will be used in an infusion pump.

If there is no infusion pump, 50 mg of midazolam, plus 50 mg of promethazine, and 50 mg of chlorpromazine are all injected into the person's body. Dr. Cai, please tell me with your expertise,

Could this be fatal?"

Cai Shude pondered for a moment before speaking: "If 50 mg of midazolam, 50 mg of promethazine, and 50 mg of chlorpromazine are injected together, it will indeed be life-threatening."

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

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

"You did not prescribe midazolam to the patient, but other doctors did. We checked the medical order and found that on the afternoon of the incident, Dr. Wang from your oncology department prescribed 50 mg for the patient in Room 3.

of midazolam, plus 50 ml of sodium chloride injection, pumped in at a rate of 2 ml per hour.

And that day, you were also working the afternoon shift, right? In other words, you and Dr. Wang worked together. When he issued a medical order, you would know it immediately, and you would even be right next to him.

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

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

"You are talking nonsense!" Cai Shude snorted coldly: "Up to now, it is just your reasoning. Where is the evidence? Didn't you say there is evidence? You should show the evidence!"

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

"What kind of evidence is this? I am not in charge of the patient in Ward No. 3, and I did not issue his medical orders. The work of administering medication and treatment was done by nurses. There is no midazolam in the infusion pump. I have nothing to do with it."

What's the relationship?" Cai Shude immediately defended.

"With the management level of your hospital, every aspect of the treatment process will be recorded. How could a drug like midazolam disappear inexplicably? Unless someone is watching to steal it!

And the syringe that killed Dr. Liu happened to contain midazolam, which means that the midazolam that was supposed to be used for the patients in Ward 3 was used by the man who stole it to kill him!" responded He Jiahui.

road.

"Even so, why do you say that I am the murderer? We also have several doctors in the oncology department. Isn't it possible that others are hiding behind the scenes?" Cai Shude asked rhetorically.

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

"What about the nurse? The nurse often goes to the dispensing room. It's possible that the nurse is stealing, right? That night, besides me, Zhou Yuting and Deng Qiaomei were also there. They might also have stolen the sedatives to kill people!

Besides, haven't you already found the key in Zhou Yuting's pocket? This is enough to prove that she committed the murder and then framed the blame!" Cai Shude immediately retorted.

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

Cai Shude was stunned for a few seconds, and his face changed slightly. He had obviously thought of the key, but he immediately forced himself to calm down and tried his best to stay calm.

"I really can't shed tears until I see the coffin. I have to explain everything clearly!" He Jiahui shook his head helplessly and continued:

"The execution time of the doctor's orders in Ward 3 is eight o'clock in the evening, which means that if the murderer wants to steal the midazolam in Ward No. 3, he must do it before eight o'clock in the evening, otherwise the drug will be used on the patient.

On the body.

The two nurses, Zhou Yuting and Deng Qiaomei, both worked the night shift and arrived at the hospital at nine o'clock in the evening. By this time, it was already past the time for Ward 3 to carry out the doctor's orders. It was impossible for them to steal the microphone from Ward 3.

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 evening. Among the three of you, only you could steal the midazolam from Ward 3! Dr. Cai, you still have

What to say?"

Cai Shude gritted his teeth. He wanted to continue to defend, but found that he had no way to defend himself.

The execution time of a midazolam doctor's order directly eliminated the possibility of the other two people committing the crime, and also pinned the murderer on Cai Shude.

Although the key was found on Zhou Yuting before, in the face of the elimination method, this kind of evidence can no longer prove her suspicion. Even if it goes to court and the benefit of the doubt belongs to the defendant, Zhou Yuting will not prosecute.

As the classic saying goes, if all impossibilities are eliminated, whatever 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 enmity with Liu Guoqiang, so why should I kill him!"

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

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

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

Dr. Sun Jiacheng has now immigrated to the UK, so there is no possibility of committing a crime. The police did not investigate him in depth at that time. However, on the way here, I called Dr. Sun Jiacheng.

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

According to Dr. Sun Jiacheng's biological account, the conflict between him and Dr. Liu Guoqiang was indeed over a scientific research project. At that time, both of them were fighting for funds, but the funds provided by the hospital were only enough for one project.

At the critical moment of fund approval, Dr. Liu Guoqiang found a handle on Dr. Sun Jiacheng, and he used this handle to threaten Dr. Sun into giving up his scientific research project. The handle was that Dr. Sun Jiacheng had sold fake "Medical Exemption Certificates"

.

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 needs to issue a "Medical Exemption Certificate"

》, you can be exempted from vaccination.

Some people do not want to get vaccinated for various reasons, but if they do not get vaccinated, their normal social life and life will be affected, so these people go to the doctor to issue a fake "Medical Exemption Certificate" so that they do not need to get the flu vaccine.

This phenomenon has also spawned many unscrupulous doctors who specialize in issuing fake "Medical Exemption Certificates" to people. One certificate can be sold for 5,000 yuan. If you sell a hundred copies casually, you will get 500,000 yuan.

For a doctor, this is nothing more than signing his name a hundred times.

Dr. Sun Ka-shing once made such shady money. When Dr. Liu Guoqiang found out, he became a threat to him. It was also for this reason that Dr. Sun Ka-shing immigrated to the UK. He was worried that if he continued to stay in Hong Kong, he would be blackmailed by Dr. Liu Guoqiang.

.

Moreover, there is no extradition treaty between the UK and Hong Kong. When he went to the UK, the laws of Hong Kong could not punish him, and the police could not catch him. It was also for this reason that he dared to reveal to us the truth about his immigration to the UK.

At the same time, Dr. Sun Jiacheng also revealed another news. The person who issued the fake "Medical Exemption Certificate" was you, Dr. Cai Shude, and Dr. Liu Guoqiang also knew about this.

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

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

Only after Sun Jiacheng obtained the promise from the police was he willing to tell the truth about his immigration to the UK and Cai Shude's issuance of a fake "Medical Exemption Certificate".

Who would confess to the police that they had broken the law if there was no benefit?

This kind of conditional exchange is very common in the British and American legal systems. He Jiahui can be regarded as learning now and applying it now, doing as the Romans do.

Issuing a fake "Medical Exemption Certificate", according to Hong Kong's Criminal Offenses Ordinance, is either a crime of fraud or a crime of making a false document. The penalty for the former is determined based on the amount, while the latter can be sentenced to up to 14 years in prison.

At the same time, doctors have also violated professional ethics and will be punished by the Medical Committee.

With his future ruined and fourteen years in prison, it is indeed enough for someone to take a desperate risk and choose to kill someone to silence him.

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