Rebirth 2014: I, the King of Criminal Investigation

Chapter 184 Some drugs can induce
On the way here, Yu Dazhang had already thought about the questions he wanted to consult.

He analyzed it from the murderer's perspective.

If you want to fool the medical examiner, the first thing you need to consider is...

Are there any loopholes in the forensic profession?
Unfortunately, the answer is yes.

The characteristics of the profession have already determined its limitations.

Although the word "forensic pathologist" has the word "doctor" in its word "doctor", they are not real doctors and cannot treat patients.

Suppose someone has a heart attack, he or she will definitely go to the hospital to see a doctor, and no one will go to the forensic doctor.

There is a word called: professional bias.

For the same thing, the results seen by an outsider and an insider are completely different.

For example, if you ask a forensic doctor about the treatment of heart disease, you are just asking for trouble.

To put it another way, you ask the forensic doctor what side effects the drugs used to treat heart disease have?

Which medicine requires attention to dosage and avoid taking too much?

It's useless to ask. Only cardiologists can answer questions like this.

but!

Side effects of drugs and excessive use of a certain drug can lead to death.

"Evidence bag..."

The male doctor carefully looked at the words on the transparent bag, then raised his head and looked at Yu Dazhang:
"Are you a policeman?"

"Yes." Yu Dazhang did not hide it and nodded in response:

"In one case, the victim had taken these two drugs before his death. He had a heart attack and died about half an hour after taking the drugs."

Perhaps because it involved professional knowledge, the male doctor couldn't help but look at the label on the medicine bottle after hearing Yu Dazhang's description.

"Metoprolol, Verapamil..."

He read it out loud unconsciously, thought for a moment, and then continued:
"One treats angina, and the other treats irregular heartbeats. These two drugs can be used together, no problem."

"Do these two drugs have any side effects?" Yu Dazhang asked.

"Of course there is. It's written on the bottle." The male doctor explained:
"Generally, drugs for treating heart disease will have some adverse reactions, which is inevitable."

Of course Yu Dazhang knew that all medicines had side effects.

He still understands the principle that all medicines are poisonous.

“Do the side effects of these two drugs pose a risk of fatality?”

This is what he wanted to ask.

A doctor's view on medicine is to cure diseases and save lives, so he is needed to provide guidance.

"No." The male doctor answered simply:

"The most serious adverse reaction is abnormal liver function, but it is not life-threatening."

The side effects have been ruled out... Yu Dazhang muttered to himself.

Then he went straight to the point:

"Then under what circumstances would taking these two drugs cause death?"

The guidance was almost complete. He thought that the doctor's thinking had been led astray by him, and it was time to ask the most critical questions.

The reason why he couldn't come up with an answer was because he was not professional enough.

But the cardiologist in front of him would not be stumped by such a question.

The male doctor thought for a moment and asked:

"How did the patient die? Please describe the symptoms at the time."

"The cause of death was sudden cardiac death. The symptoms..." Yu Dazhang recalled, but couldn't think of the right words to describe it.

In the end, he simply imitated Liu Zhengyang's behavior.

His eyelids drooped, his head drooped, and he fell on the table. Then his body gradually became limp and weak, like a puddle of mud, and he collapsed to the ground.

The male doctor thought it was a little funny at first, but as he watched, his expression gradually became serious:
"Alright, alright, get up."

Yu Dazhang sat back down and looked at him expectantly: "How is it, did you figure out anything?"

He was confident that the imitation he just made was highly accurate.

An experienced doctor can analyze the patient's specific condition through symptoms.

Sure enough, the male doctor only hesitated for a moment and quickly replied:

"Cardiac arrest."

"From your performance just now, it seems that the patient suddenly lost consciousness."

"This symptom will only occur if the heart's ejection function suddenly stops, the pulsation of the large arteries and heart sounds disappear, causing the brain to be ischemic and hypoxic."

Yu Dazhang was not unfamiliar with this professional term, but it was not what he was interested in.

He thought about it and continued to ask:
"Is it possible that these two drugs could cause such a result?"

More detailed than the cause of death given by the forensic doctor, this is the professionalism of a cardiologist.

Next, he just needs to determine whether these two drugs are related to the cause of death.

"An overdose of Verapamil can induce cardiac arrest." The male doctor answered carefully:
"But such mistakes should not happen. These drugs have clear dosage standards and precautions, unless the patient deliberately takes more."

Did Liu Zhengyang commit suicide? After listening to his analysis, Yu Dazhang suddenly had this thought.

However, he quickly rejected this idea.

If he wanted to commit suicide, Liu Zhengyang would have to take any medicine, but he had to take verapamil, a heart disease medicine.

Moreover, according to the housekeeper's description, Liu Zhengyang took the medicine in normal dosage before the meeting and did not take too much.

"Thank you, doctor."

After expressing his gratitude, Yu Dazhang stood up and left the Department of Cardiology.

He had asked all the questions that needed to be asked, and had answers to the most puzzling questions, but he felt even more depressed than when he first came.

The murderer's intelligence and planning ability have exceeded his imagination.

This can no longer be described as clever or cunning, it is simply perfect planning.

Listen to the word the doctor just used: induce.

No wonder the medical examiner concluded the death was natural.

There is an essential difference between inducing and causing.

"Verapamil" itself is a drug for treating heart disease, and Liu Zhengyang usually takes this drug to maintain his heart rate.

Therefore, even if the forensic doctor detected "verapamil" in Liu Zhengyang's body, he would not doubt it.

What a clever design! Whoever came up with this idea took human nature into consideration.

This is not over yet.

You know, before the meeting, Liu Zhengyang took the same dosage of medicine as usual.

How did the murderer manage to make him take too much Verapamil and induce cardiac arrest?

In Yu Dazhang's opinion, the trap set by the other party was one link after another.

Even if the drugs were swapped, this wouldn't be possible.

No third drug was detected in Liu Zhengyang's body.

So even if the drugs were switched, the murderer still tampered with these two drugs.

How could someone manipulate Liu Zhengyang to make him take too much of the drug "Verapamil" at one time?
Yu Dazhang had already arrived at the hospital gate.

He looked at the people coming and going in the hospital for a long time without moving.

My mind is constantly running through what-ifs.

After a long while, he came to his senses and sighed helplessly.

Damn, with this IQ, he will succeed in everything he does... he complained in his mind.

Just a moment ago, he was led into a misconception by the other party's thinking.

No matter how hard you think, you can't guess what the other party will do.
