Chapter 239 Two injections of medicine (12)

While Masumi Sera, Ginzo Nakamori and others were checking the surveillance video,
Another phone call came in.

"Mr. Tsukino is awake!"

Ginzo Nakamori said excitedly after hanging up the phone.

So they hurried to the hospital where Takashi Tsukino was.

Ginzo Nakamori and Masumi Sera first confirmed with the doctor the cause of Takayasu Tsukino's coma.

"We found diazepam in Mr. Tsukino's blood."

The doctor said to Ginzo Nakamori and Masumi Sera.

"In other words, Mr. Tsukino must have fallen into a coma because of taking sleeping pills."

"So that's it."

After understanding, Nakamori Ginzo continued to ask:

"Excuse me, could you tell me the time when Mr. Tsukino took the sleeping pills?"

"It shouldn't take too long for Mr. Tsukino to take the medicine, probably within four or five hours."

"This is impossible!"

Nakamori Ginzo flatly denied this possibility.

"We have confirmed that Mr. Tsukino had fallen into a coma at around 0:20 this morning."

"So Mr. Tsukino should have taken the sleeping pills at least nine hours ago."

Ginzo Nakamori was a little confused. How could the doctor come to such a conclusion?

"Doctor, did you make a mistake in the test?"

“The data don’t lie.”

The doctor is confident in his judgment.

"So, is it possible that Mr. Tsukino has a problem with his gastrointestinal tract or liver, which has prolonged the half-life of diazepam's concentration changes in the body?"

Sera Masumi asked.

"Our hospital has Mr. Tsukino's physical examination records from a month ago. Although he is nearly 40 years old, all his physical values ​​are normal."

the doctor answered.

Upon hearing this, Sera Masumi also showed a slightly confused expression.

"It's not a test error, nor is there a problem with my physique. Could it be that...?!"

After thinking for a while, she asked tentatively:

"Is the level of nordiazepam in Mr. Tsukino's body too high?"

"What do you mean?"

The doctor didn't quite understand what Masumi Sera meant.

"As I recall, unlike triazolam, which has a relatively short half-life, diazepam has a very long half-life in the human body."

"About 20 to 50 hours."

"Then is there a possibility that the reason why Mr. Tsukino's diazepam concentration is high is because he took sleeping pills twice?"

"Because the human body metabolizes diazepam very slowly, I guess Mr. Tsukino might have been given a sleeping pill again before the first dose of diazepam was completely metabolized."

"This caused the diazepam concentration in his body to exceed normal levels, affecting the doctor's judgment."

Sera Masumi said.

Masumi Sera's statement also reminded the doctor.

The doctor realized that this was indeed a possibility, so he hurriedly checked Takashi Tsukino's medical report again.

Then, he looked at Sera Masumi with surprise.

"Really? Mr. Tsukino's level of nordiazepam is higher than normal. He must have taken sleeping pills twice!!"

"What does this mean? Why don't I understand?" These chemical names were simply a blind spot for Ginzo Nakamori.

He listened to the conversation between Sera Masumi and the doctor and felt confused.

"What does the concentration of nordiazepam have to do with Mr. Tsukino taking two sleeping pills?"

Then he heard Sera Masumi explain:
"The concentration of diazepam that Mr. Tsukino took the second time was added to the concentration of the first time, causing the concentration of diazepam in his body to be higher than normal."

"So we can't tell whether Mr. Tsukino took the sleeping pills twice, or whether he actually hid the sleeping pills and secretly took them four or five hours before."

Ginzo Nakamori nodded upon hearing this.

"Diazepam is metabolized in the human body and converted into metabolites, which are nordiazepam."

"If Mr. Tsukino secretly took diazepam on his own early this morning, then the concentration of nordiazepam in his body should not be so high."

"Because this period of time is not enough for him to metabolize so much nordiazepam."

"So, it could only be that Mr. Tsukino had already taken sleeping pills once earlier."

After hearing Sera Masumi's explanation, Nakamori Ginzo finally understood everything.

The doctor standing by listened to Sera Masumi's reasoning, and the look of surprise in his eyes became more and more intense.

He really didn't expect that this young and handsome mixed-race "handsome guy" actually knew so much.

Not only did he notice things that even he, a professional, had overlooked.

And he deduced the truth of the matter so quickly.

As expected, being a detective is not a profession that ordinary people can do!

"If that's the case, Mr. Tsukino should have taken a sleeping pill yesterday morning."

"The exact time needs further analysis, but it was roughly around this time yesterday morning."

The doctor said to the two of them.

Masumi Sera and Ginzo Nakamori thanked the doctor and then came to the ward where Takashi Tsukino was.

Here, the two met Tsukino Takashi, who still looked a little depressed.

Ginzo Nakamori already knew Takayasu Tsukino, so there was no need for him to introduce himself to Takayasu Tsukino.

He just introduced Masumi Sera who was beside him to Tsukino Takashi.

Indicates that she is a detective who came to help.

"Mr. Tsukino, may I ask what exactly happened?"

Ginzo Nakamori went straight to the point.

"Yesterday I was going to the venue for rehearsal, but somehow I lost consciousness."

"In other words, Mr. Tsukino, you fell into a coma yesterday morning?"

"probably."

Tsukino Takashi answered in a daze.

"It seems there is no problem. It is consistent with your reasoning, Miss Sera."

Ginzo Nakamori looked at Masumi Sera, and then saw Masumi Sera nodded at him.

"Mr. Tsukino, do you have any memory of being drugged?"

"No."

Tsukino Takashi shook his head.

Nakamori Ginzo looked at Sera Masumi again, asking with his eyes whether what Takashi Tsukino said was true.

"Diazepam is a powerful sedative and hypnotic drug. Generally speaking, only 20 mg can put an adult with no drug tolerance into a deep coma for several hours."

"Even if 30 milligrams of diazepam was dissolved in a drink, it would not be detected, so it is very likely that someone put the drug in Mr. Tsukino's morning drink."

Masumi Sera spoke up, indicating that there was nothing wrong with Tsukino Takashi's statement.
