If Chinatsu Aihara had simply reported her teacher's illegal behavior, there would be nothing much to say.
But not only did she report the other party, she also poisoned him to death, which was a bit too much.
Anyway...
Sakaki Makoto couldn't stand it.
After being exposed, Chinatsu Aihara did not give up on herself, but gradually calmed down.
She had no way out.
What has been done has been done, it's too late to regret.
Seeing that the other party showed no sign of admitting guilt, and even showed no remorse...
Sakaki shook his head and sighed, saying:
"As Saijo Masato's favorite disciple, you must be familiar with his daily routine and living habits."
Without waiting for Aihara Chinatsu to answer, he continued:
"Although the method you used was simple, it was very clever..."
"Inspector Megure, let those who are not involved wait aside and rest."
"good."
Nodding, Megure Juzo sent Takagi Wataru to evacuate the crowd.
After the surroundings were quiet, Sakaki Makoto said:
"Because VX nerve agent is volatile in the air, you diluted the agent, dripped it into the cigarettes that Nishijo Masato liked to smoke, and stuffed it back into the box."
"Masato Nishijo, who is a heavy smoker, goes out to smoke after almost every performance."
"This way, you can roughly estimate how long he was poisoned."
"Well, that sounds quite plausible."
With her arms folded, Aihara Chinatsu said calmly:
"Since I poisoned the cigarettes, there should be toxins left in the cigarette butts."
"Have you detected it?"
Megure Jusan's face darkened slightly.
Shortly after Masato Saijo's death, the Forensic Investigation Division conducted a thorough inspection of the lounge.
Including the box of cigarettes on the table.
The strange thing is...
No toxic reactions were found.
The cigarettes were also ordinary ones, the kind that cost a few hundred yen a pack on the market.
"I'm afraid you disposed of the cigarette box immediately after Nishijo Masato finished smoking..."
Sakaki Makoto didn't react, which was within his expectations.
"Just throw the cigarette box and cigarette butts into the bonfire, and they will disappear without a trace in the blink of an eye."
"The trace amounts of toxins left behind, diluted by the air, can do little harm to the human body and can be ignored."
The actual place where the VX neurotoxin is dropped is in the tobacco.
The poison enters Nishijo Masato's lungs along with the smoke, and even with a filter, it is impossible to achieve 100% filtering.
"So!"
Aihara Chinatsu smiled complacently:
"Solving a crime requires evidence, Mr. Detective."
"We need evidence."
Sakaki Makoto said calmly:
"In this case, you used a variety of tools, such as droppers and measuring cups commonly used in laboratories..."
"These are made of glass. Even if you throw them into the fire, there is no way they will disappear without a trace."
"Besides, there are still toxins left in it. You wouldn't dare throw it into the trash can. If the police find it later, it could become evidence against you."
"So....you chose another way to deal with it."
Aihara Chinatsu's gaze gradually became gloomy.
Makoto Sakaki was like a worm in her stomach. He didn't see her commit the crime, but he could tell her everything accurately.
It would be a lie to say I wasn't scared.
But she would not plead guilty out of fear.
"Nerve agents are indiscriminate chemical weapons. Even if you dissolve them in water in the form of ice cubes, they will still evaporate into gas."
Pushing his sunglasses, Sakaki Makoto turned and looked towards the woods:
"So, after you drop the liquid containing the toxin into the cigarette, you need to immediately dispose of it harmlessly."
"The method is very simple. Just throw it into the liquid nitrogen tank."
"Liquid nitrogen tank?"
Aihara Chinatsu raised her eyebrows:
"You mean the liquid nitrogen tank I took out?"
"Don't be stupid. If there is any neurotoxin in it, wouldn't we know if we check it?"
"No, what you took out was the liquid nitrogen tank that belonged to Masato Nishijo."
Sakaki stared into her eyes and said word by word:
"You also prepared another liquid nitrogen tank!"
"I thought you were going to say something..."
Aihara Chinatsu curled her lips in disdain:
"We haven't left the circus at all since we came to Tokyo."
“This has been confirmed by everyone.”
"Besides, the police searched the circus thoroughly and did not find a second liquid nitrogen tank, so..."
"Excuse me, Mr. Detective, where can I hide the liquid nitrogen tank?"
Amid the chirping of cicadas, beads of sweat the size of beans rolled down my cheeks.
Megure Jusan looked at Sakaki Makoto nervously.
This is the strangest part of the case.
If Chinatsu Aihara prepared a second liquid nitrogen tank, why didn't the police find it?
Could it have been thrown into the trash can and taken away with other discarded garbage?
That's a big deal...
Is it possible that the VX nerve agent leaked?
"The liquid nitrogen tank you use is not big. A 1L tank is about the size of a human head..."
Just like rolling a Rasengan, Sakaki Makoto made a hand gesture:
"This is also the most ingenious part of your modus operandi."
"As the saying goes, the most dangerous place is the safest place. You took advantage of people's blind spots..."
"It also played a time difference game."
With her brows furrowed, Aihara Chinatsu asked:
"What's the meaning?"
