After some interrogation, Maori Kogoro finally figured out what happened.
During the lunch break, Takasugi Yuto was killed by a murderer in the seminar room. The first person found was his girlfriend Suzumura Rin who came back to bring him food.
Later, Himuro Takashi, who was cleaning the air conditioner in the nearby corridor, heard the sound and rushed over and called the police. Shortly afterwards, Meguro and their mentor Shogo Kunimatsu also returned from the cafeteria and jointly protected the scene from being destroyed.
During this whole process, Maori Kogoro had already noticed a suspicious point.
"That's it! I completely understand!"
In the temporary lounge, after careful thinking, Mouri Kogoro suddenly shouted loudly.
"Wha, what?!" Takagi Wataru on the side suddenly exclaimed: "Does Mr. Mori already know who the murderer is?"
"Ah, that's not the case yet..." Mouri Kogoro touched his head in embarrassment, and then said with a serious face: "But, I have cracked the murderer's murder method!"
"well?"
Conan, who was still deep in thought, looked over curiously when he heard this.
[Uncle, are you...]
"The murderer's method is very simple!"
Standing up from his seat, Mouri Kogoro said calmly with a confident smile on his face:
"The murderer must have used some kind of special poison to kill the victim. As for the method of poisoning, it was the oxygen bottle that the victim often used during his lifetime!
That oxygen bottle was actually a poison gas bottle that had been secretly swapped by the murderer! As long as the poisonous gas that can cause respiratory failure is put into it, and the victim is forced to inhale the poisonous gas during lunch break, he can be killed smoothly! Wa hahaha! "
"Ha, haha..." After hearing this reasoning, Conan suddenly turned into a dead fish eye.
"Is this how it was originally done?"
Hearing this, Gao Mushe had a somewhat puzzled expression on his face.
"Well, I'm sorry, Mr. Maori... We didn't detect any toxic reaction on that oxygen bottle..."
"ah?"
Mouri Kogoro's laughter stopped abruptly.
"This is the report just submitted by the forensics department. There is no poison reaction at all, either on the oxygen bottle or inside the bottle."
"Ah, this, that... I think the murderer should have eliminated traces of the poison afterward! Yes! That's it!
Suzumura-san and the others have said this before, right? The oxygen bottle showed signs of being tampered with after they left! The murderer must have released all the remaining poisonous gas in the bottle after committing the crime! That must be it! "
【How is this possible...】
When Conan heard this, he sighed helplessly and couldn't help but say:
"Now, but uncle, the door, windows and curtains of the seminar room are always closed, right? If the murderer put poisonous gas into the air, then the Suzumura sister who opened the door first would have also inhaled a small amount of poisonous gas, right? "
"Uh, this, that...ahem." When Conan asked and had nothing to say, Mouri Kogoro could only sit back with an embarrassed look on his face.
Although the reasoning was full of loopholes, Conan did notice something mentioned in his words.
It's that oxygen bottle.
According to Suzumura Rin and others, before they left the seminar room, the oxygen bottle was thrown directly on the ground by Takasugi Yuto who woke up and fell asleep. However, when they came back from the cafeteria, the oxygen bottle was in good condition. placed on the coffee table.
Excluding the possibility that Takasugi Yuto woke up in the middle, this oxygen bottle with different front and rear positions should have some relationship with the murderer, and it may even be one of the key means for the murderer to cause Takasugi Yuto to suffocate strangely.
[Let’s go take a look in the seminar room again. There will definitely be some clues there. 】
With this thought in mind, Conan quietly stood up, left the lounge, and returned to the seminar room again.
In the seminar room at this time, since the police had basically completed the on-site investigation and evidence collection, and Takasugi Yuto's body had been removed, the police did not continue to block the place, and Conan walked in easily.
"well?"
As soon as he entered the seminar room, Conan found that there were already people inside.
"Suzumura-nee?"
In the room, Suzumura Rin stood in front of the desk with garbage piled underneath, looking sad.
Hearing Conan's voice, she looked back with surprise in her eyes.
"Little brother, why are you here?"
"Ah, Uncle Maori asked me to come over and investigate the scene again, looking for any missing clues...Sister Suzumura, why are you here?"
Conan pretended to be a primary school student very skillfully, walked up to her, looked up at her, and asked in a cute tone.
Suzumura Rin, although this person is Takasugi Yuto's girlfriend, he himself has serious suspicions.
First, she was the first person to discover the scene.
Secondly, according to Meguroto and Kunimatsu Shogo's oral statements, after they returned to the seminar room, Suzumura Rin was crying while holding Takasugi Yuto's body.
If she is the murderer, then she herself has great conditions to commit the murder and the opportunity to clean up the scene afterwards.
"I...want to come and see Yuuto..." Suzumura Rin replied as Conan looked directly at him.
"Huh? So this table and chairs belong to Brother Takasugi?" Hearing this, Conan looked at the table and chairs piled with garbage in front of him and asked in pretending surprise:
"It looks so dirty. There are garbage piles everywhere. Doesn't Takasugi-san usually clean it?"
"I have told Yuu Dou before that I originally wanted to help him clean up yesterday, but he stopped me...
She said she was no longer a child and could clean her own things, but in the end she was too lazy to do anything... Really, it doesn't make people worry at all..."
"Suzumura Rin" said this with a complicated and sad expression on his face.
For Mizuna Reina, a performance of this level is quite easy.
From yesterday to today, she has been pretending to be Suzumura Rin for two days.
After just two days of observation, she was vaguely sure of one thing.
Takasugi Yuto might really be hiding something, and it should be in this pile of garbage.
This is not Shui Wu Reina's random guess.
When she had just replaced Suzumura Rin and returned to the seminar room during the day yesterday, she remembered that Takasugi Yuto was rummaging for something in this pile of garbage, looking flustered.
And in the evening, when she offered to help Takasugi Yuto clean up the garbage, he forcefully refused because he knew how to clean it.
If it were other people, they might not take it seriously, and they would just complain a few times.
But Reina Mizuna was different. She had been warned by Regel before this operation. Yuuto Takasugi was likely to carry information about Mitong Owada's identity.
Therefore, after noticing these abnormal behaviors of Takasugi Yuto, she keenly realized that there was probably something she was looking for hidden in this pile of garbage.
