Rebirth 2014: I, the King of Criminal Investigation

Chapter 196 Genius and Madman

Drug purification?

When Yu Dazhang heard these four words, the expression on his face was very interesting.

I know how Liu Zhengyang died...some things that he couldn't figure out before now all became clear to him.

How could Liu Zhengyang take too much verapamil at one time without changing the dosage?
Yu Dazhang thought about this question many times.

But the answer came out of Liu Miao's mouth.

That’s right, it’s drug purification.

Tablets are mainly composed of two parts, namely the active ingredients of the medicine and pharmaceutical excipients.

Usually the active ingredient is only a few milligrams, and the rest are all excipients, and most of the excipients in tablets are starch.

The ratio between the two is about one to one hundred.

After purification, the ratio is readjusted to increase the proportion of the effective ingredients of "verapamil".

For example, increase the ratio from one to one hundred to one to twenty.

This is equivalent to increasing the efficacy of the drug five times.

If Liu Qi was the murderer, she must have used this method.

Yu Dazhang thought about it again and felt that something was not right.

Liu Qi majored in natural science at Cambridge, a comprehensive subject that includes medicine.

A top student like her should be able to purify the drugs by herself.

Then why did she commission the laboratory to conduct drug experiments?

This involves professional knowledge...Yu Dazhang knows nothing about medicine and cannot make any judgment on this.

But one thing can be inferred.

There must be a step that Liu Qi cannot complete by himself.

"Isn't there any record of the data from that experiment on the computer?" Yu Dazhang asked.

Today is the Internet age, and data is usually recorded in two ways: online and offline.

A national key laboratory like this will definitely have an online system dedicated to recording data and will set up password protection measures to prevent information leakage.

"I have asked and asked the lab staff to check, and there is no relevant record online."

Liu Miao analyzed the situation:

"There are only two possibilities for this outcome."

"First, the experimenter who was responsible for the purification did not record the experimental process online."

"Second, someone deleted the records on the computer."

"I also asked the experimenter, and he said it was too long ago and he couldn't remember clearly."

Can't remember? Yu Dazhang thought this reason was far-fetched.

Anyone who can work in a national key laboratory must have no problem with IQ, not to mention good memory.

Just like handling cases, criminal police have extremely deep impressions of the cases they have personally handled.

No matter how old the case is, once it is mentioned, it can be recalled immediately.

Similarly, an experimenter will not forget the experiments he has personally conducted.

"You stay there and continue investigating." Yu Dazhang ordered:
"Pay special attention to that experimenter."

They are all experienced criminal investigators, so there is no need to tell each other the direction of the investigation in detail. They can understand the meaning of it with just one sentence.

What to focus on?
The other party's living conditions, whether they have foreign debts, whether they have unknown income...

It can be said that criminal police are very familiar with investigating these matters and they face no pressure at all.

After ending the call, Yu Dazhang took out the notebook and added a question mark after Liu Qi's name.

All online and offline records are lost, and the original experimental products have also been stolen.

Did Liu Qi hire someone to do it?

To erase all traces of the experiment?

That's too deliberate.

Just destroy it secretly. Wouldn't it be more likely to arouse suspicion if you make it look like a theft?

With Liu Qi's intelligence, how could he make such a low-level mistake?

Was this also a trap she set up on purpose?

will not.

She had already set the trap when the drugs were swapped.

In her plan, no police officer would be able to find the laboratory. In other words, if someone really found this place, it would be useless to use some tricks.

But the main purpose of this internal theft was to help her erase traces of the experiment.

Is there someone else involved in this case?

Yu Dazhang couldn't help feeling a little confused at this moment.

"What on earth do you want to do?"

He stared at the names of Liu Qi and Liu Siyuan on the notebook, his eyes moving back and forth.

Just as Da Zhang was thinking, his cell phone rang again.

He glanced at the caller ID, Ye Lin!

"The results of the investigation have been passed on to you."

Ye Lin's voice came from the phone. She spoke quickly and without hesitation:

"This woman is indeed problematic. She voluntarily gave up her Cambridge degree and suddenly returned to China. The first thing she did after returning was to find someone to clean up her past."

Zeng Lisi is also from Cambridge University?!
When Yu Dazhang heard the news, he immediately thought of Liu Qi.

These two people are actually alumni!

"Are you sure she has washed her bottom?" Yu Dazhang wanted to confirm it again.

"Of course." Ye Lin answered confidently:
"The other party's method of cleaning up their reputation is not very sophisticated, and an expert can see it at a glance."

It is enough to be sure of this.

Yu Dazhang did not expect the National Security Bureau to help him find out the specific process of cleansing his identity.

"Thank you. I owe you a favor this time."

Ye Lin ignored his politeness, said "huh" and hung up the phone.

Coming to the computer, Yu Dazhang opened the communication software and opened the information sent by Ye Lin on the computer.

Zeng Lisi entered the University of Cambridge to study psychology in 2009.

He performed outstandingly during his time at school. One year later, he was given a verbal warning by the school for academic misconduct because he hypnotized his classmates.

In 2011, he was again given a written warning by the school for hypnotizing his classmates and teachers.

At the beginning of 2013, a number of classmates and teachers were subjected to collective hypnosis, which caused one of the students to suffer a psychological breakdown and commit self-harm.

Afterwards, many teachers and students came forward to plead for her, so that she was not expelled from school.

But in early June of the same year, Zeng Lisi gave up her academic qualifications and resolutely chose to return to China, choosing Songhai City as her destination.

This is a madman... Yu Dazhang's eyes twitched wildly after reading the survey results.

He counted on his fingers.

Since Zeng Lisi entered school, she has been caught hypnotizing her classmates and teachers three times by the school.

The last time there was an incident of self-harm.

This is just what is on the surface, what about what has not been discovered?
Since she has the ability to hypnotize her classmates and teachers, it means that her hypnosis level is far higher than others.

The psychology program at Cambridge University is world-class.

Anyone who can study there would be top-notch.

In other words, Zeng Lisi is a genius among geniuses in psychology.

And there is another name for genius...

madman!

When a person focuses too much on one thing, he or she may develop paranoia symptoms.

When paranoia reaches a certain level, one will become arrogant and think that no one in the world can compare to oneself.

At this moment, it is hard to imagine what crazy thing she would do.

Yu Dazhang looked at the information on the computer screen and smiled unconsciously.

"You are an interesting alumnus."

Others go to Cambridge University to learn knowledge, but she learns and applies it immediately, practicing directly with her classmates and teachers.

PS: The day before yesterday, I went home to have a small gathering with friends before the New Year. I drank too much and was still drunk yesterday. I gritted my teeth and wrote two chapters. I didn’t dare to write about logic, so it’s a bit watery…

Li Bai wrote hundreds of drunken poems, and I got a lot of drunken poems wet.

Ultimately, it’s because of the lack of skills.

Sorry.
