The originally simple case suddenly became extremely difficult due to the death of Masato Nishijo.
No one knows how Masato Nishijo was poisoned, let alone when he was poisoned.
everything...
We have to start from the beginning.
The detection of VX neurotoxin requires the use of professional instruments, which is not something that Makoto Sakaki can handle with just his own hands and knowledge.
Testing takes a lot of time, obviously....
The Metropolitan Police Department can't wait.
It is better to believe it than not to believe it. If the criminal really used VX nerve toxin, then the nature of this case is extremely bad.
“We must investigate thoroughly!”
Megure Jusan clenched his fist and said loudly:
"We must not allow prisoners to use chemical weapons!"
Sakaki Makoto, Conan, and Hattori Heiji immediately agreed:
"That's right."
"Chemical weapons are indiscriminate attacks, and VX nerve toxins are lethal. We must find the source."
Although...
No signs of poisoning have been found on other people so far. The criminal probably did not want to harm innocent people and only used the neurotoxin on Masato Nishijo.
but....
No matter what the other party's purpose is, highly lethal chemical weapons like VX nerve toxin cannot be left unattended.
After knowing that the place where Nishijo Masato was poisoned was not in the lounge, Megure Juzo became bolder.
He walked out of the lounge and asked Takagi Shigeru to call the circus members backstage for questioning.
It varies from person to person. VX neurotoxin cannot kill instantly. Its onset usually takes tens of minutes or even hours. In some cases, typical symptoms may not appear until more than ten hours later.
The so-called typical symptoms usually refer to excessive accumulation of acetylcholine in the body, which causes pupil constriction, eye pain, blurred vision, cough, chest tightness, rapid breathing, headache, and nausea.
In the beginning...
Sakaki Makoto did notice something strange about Saijo Masato.
but...
He thought it was because of the weather and his guilty conscience.
Who would have thought...
Was Nishijo Masato actually poisoned?
Two murders occurred in a short period of time, at the same location, with different perpetrators. This situation...
Sakaki Makoto hasn't seen him much.
I was careless.
As long as the onset time of the VX neurotoxin is known, the scope of investigation will be narrowed accordingly. Megure Jusan made a rough estimate and gave a range:
"It's 12 noon now. If we count 20 hours..."
"Did Masato Nishijo leave the circus between 4pm yesterday and just now?"
The circus members gathered together and whispered to each other, apparently discussing something about Masato Nishijo.
According to common sense...
It would be more effective if the police separated the suspects when questioning them.
However, due to time constraints, the most urgent task was to determine the location where the neurotoxin appeared, so Megure Jusan had to resort to other means.
Within just one hour, the troupe leader and deputy troupe leader died one after another. It would be a lie for the members of the Sunshine Circus to say they were not terrified.
They were trembling with fear at the moment, how could they dare to hide it?
I just hope the police can catch the criminal as soon as possible to avoid any more trouble.
"No..."
After waiting for a while, a member finally spoke up. It was Xiao Qian, who was in charge of the flying trapeze project:
"Our group arrived in Tokyo three days ago and plans to perform for a month."
"Because they have to perform for 12 hours every day, the members are very tired and don't have much time to rest. Except for buying food, they usually don't leave the backstage..."
"Originally, the leader was planning to invite us to drink together tonight..."
As she spoke, her tears began to fall down her cheeks like beads falling off a string.
It is not only a feeling of mourning for the group leader, but also a feeling of confusion and melancholy about the future.
"That is to say..."
His eyes lit up, and Megure Jusan asked:
"Has Nishijo Masato not left this area since yesterday?"
"Um...."
Xiao Qian nodded:
"If there is nothing else, Vice Captain Nishijo usually stays in his lounge..."
“I see.”
Megure Jusan looked at Sakaki Makoto and whispered:
"Brother, I guess the criminal who poisoned the food is in the Sunshine Circus!"
"What do you think?"
"............"
This is not nonsense...
It has been made very clear that Masato Nishijo has never left the circus, which naturally rules out the possibility of an outside attacker.
Sakaki really wanted to say this, but...
He patted Megure Jusan on the shoulder and said encouragingly:
"Good reasoning!"
"But there is another question. Nishijo Masato has never left the circus, so has he ever come into contact with people outside the circus?"
“How is liquid nitrogen obtained?”
Hearing this, Xiao Qian said uncertainly:
"Probably... not."
"In the past two days, Vice-President Nishijo has only interacted with a few guests, and in public..."
"It's impossible to hide any liquid nitrogen tanks..."
Hearing this, Sakaki Makoto began to form an idea of the case in his mind.
Liquid nitrogen tanks can be placed in luggage and carried around with the circus.
Besides....
Nishijo Masato might have already started the action, but Captain Haneda was lucky and the lock never broke.
Wait a minute!
Sakaki Makoto's body suddenly shook.
Assumption: If Masato Nishijo planned to go backstage and quietly deal with the liquid nitrogen tank after the death of Haneda, under the pretext of pharyngitis...
