This was roughly the situation before Oiso Nagami's death.
"The situation is generally understood."
After hearing the news, Karasawa looked at everyone and asked, "Then I would like to ask, was there anything strange when you left the road and discovered Oiso Nagami?"
"The two hotel attendants who started to notice something strange in the pool said that when they checked the pool ten minutes ago, there was nothing there."
"In addition, after Manager Toshima found the body of the eldest lady jumping into the swimming pool, he said that there was glass in the swimming pool." Sera Masumi followed closely and echoed: "That's pretty much it."
"Dr. Aso, how about the autopsy report?"
After hearing everything that happened before Oiso Nagami's death, Officer Megure looked at Aso Minoru who was inspecting the body and asked.
"The deceased was definitely drowned. The estimated time of death is between 12 o'clock and 13 o'clock." Aso Minoru nodded.
"But I still don't understand something."
Officer Megure said this and looked at the swimming pool next to him: "The depth of this swimming pool is not so deep that she cannot stand. Why did she drown in such a shallow swimming pool?"
"Perhaps it's because she's carrying an oxygen tank on her back." Laito Sanomaki heard this and explained: "And in order to make it easier to find the necklace, she also hung a heavy object around her waist."
"At that time, the eldest lady said she wanted to carefully search the bottom of the swimming pool." Toshima Enzai said.
"In other words, after driving you out, I will search the swimming pool for the whereabouts of the necklace?"
Officer Memu nodded when he heard this and said: "If that's the case, it would be really dangerous if there is no one around if an accident occurs.
Since this is the case, there is a possibility of accidental death."
"Indeed." Takagi said this and looked at the diving equipment next to him: "The more likely situation is that the deceased was diving with a heavy oxygen bottle strapped on, and then suddenly encountered an emergency of leg cramps.
Then this sudden situation made her panic and accidentally let go of the oxygen respirator in her mouth, and she started to choke on water.
Under such circumstances, drowning is not impossible."
"I don't think that's the case."
At this moment, Karasawa on the side suddenly said: "I remember Conan and the others just said they were concerned about something, one of which was that there was nothing in the swimming pool ten minutes before the body of Nagami Oiso was found.
The two waiters over there should be able to prove this, right?"
"That's right." The waiter nodded after hearing this: "The two of us and Manager Toshima and the other three have been investigating the whereabouts of Miss Yongmei.
But after arriving at the swimming pool, I found that there was no eldest lady in it at all.
But when we came to the swimming pool ten minutes later, we found that the eldest lady had somehow appeared at the bottom of the swimming pool."
"This scene is indeed a pity." Officer Megure nodded after hearing this.
"Then I wonder if you still remember what time it was?" Takagi asked.
"I remember it was around 2 p.m.," one of the waiters said.
"Hey, isn't the presumed time of death between 12 noon and 1 pm!?" Officer Megure was shocked when he heard the news.
"The time of death of a person does not change, so the answer is actually very obvious."
Karasawa said: "Someone killed Nagami Oiso between 12 noon and 1 p.m. and hid her body. Then at 2 p.m., it was in the middle of the swimming pool where the body was thrown."
"Then, given the situation you were in at that time, is there any way to do this kind of thing without anyone noticing?" Officer Megure asked, looking at Toshima Nosaku.
"I think it's unlikely." Toshima Enze replied after hearing this: "At that time, most of us were scattered in various places in the hotel to search for the whereabouts of the eldest lady.
It seems a little impossible to move the body away from the sight of so many of us."
After hearing the manager's words, Oiso Hamaka and Sanomaki Raito also nodded in agreement, obviously holding the same view.
"Not only that, there is a receptionist at the entrance and exit of the swimming pool who is responsible for confirming the information of the people entering."
Toshima Enzai explained: "If a suspicious person comes in and out with the body of the eldest lady, he will definitely be discovered."
"In other words, the swimming pool was actually a large secret room at that time." Sera Masumi said with a smile.
"And the glass fragments in the swimming pool are also very concerning." Conan on the side said: "Manager Toshima got his foot injured because of the glass inside."
"That's right, I jumped down and salvaged the eldest lady with Mr. Zuoma, but I didn't expect that there was glass at the bottom of the water." Toshima Enzai said: "But when we were looking for the necklace with the eldest lady, there was still glass in the swimming pool.
no."
"Officer Megure, I'm a little concerned about the broken glass. It may be related to the prisoner's trick to hide the deceased."
Tangze suggested: "Drain all the water in the swimming pool, and let's carefully check the situation inside the swimming pool.
I suspect there may be other clues that we can't see right now."
"Well, just do as you say, brother Karasawa." Officer Megure nodded, and immediately ordered Takagi: "You ask the hotel staff and ask them to pump water."
"Understood!" Takagi nodded when he heard this, then turned and left immediately.
The water was pumped very quickly. After everyone stood by the pool and waited for a while, they saw the water level drop, and the scene inside the pool was quickly revealed.
Everyone scanned the bottom and soon discovered a large number of glass fragments near the entrance and exit stairs of the swimming pool.
"Why are there so many shards of glass?"
Officer Megure followed Tang Ze and others down to the bottom of the swimming pool. He looked at the fragments on the ground and said in surprise: "It's all broken into pieces. Looking at it like this, it should be difficult to see the original appearance without putting it back together."
"It's the sink."
The three of them spoke in unison. After speaking, they found that the other two people also said the same thing as themselves, and couldn't help but look at each other and smile.
"Sink?" Officer Memu said in surprise.
"The lock piece that Takagi is holding in his hand is not flat, but is a three-dimensional image of the corner of the box, and there are four "L" shaped pieces."
Karasawa put on his gloves and quickly picked out two shaped pieces, then roughly put them together on the ground, and a cube shape was revealed.
"It really is!"
Although the four corners in the air were not supported and were placed on the ground by Karasawa, as long as he thought about the assembled parts, Officer Megure could see that it was a rectangular water tank.
