Stay away from Conan.

"Ok?"

Upon hearing that someone from the Forensic Department was coming to report the situation, Inspector Megure couldn't help but be very surprised, because he didn't know what was going on. How did Gao Yuan suddenly have clues that he wanted the Forensic Department to investigate?
In response to this, Gao Yuan couldn't help but ask:
"how?"

Faced with such inquiries, the forensic department staff naturally responded:
"According to your request, Mr. Akechi, we compared the fingerprints on all the buttons in the elevator. On all the other buttons that still have fingerprints, the fingerprints on them do not cover Ohba Satoru's fingerprints on the top. From this, we can judge that Ohba Satoru has not pressed the buttons for these elevator floors in the recent past."

After hearing this, Officer Megure realized what Gao Yuan had asked the police to investigate. It was the follow-up of Gao Yuan asking the Forensic Department to check the fingerprints in the elevator. However...

It is not clear what use this clue will have once it is found.

Therefore, Inspector Megure looked at Gao Yuan in confusion, wanting to know what the purpose of these clues was.

With this information, Gao Yuan was still far from finding out the truth, but at least he was sure of one thing.

"Officer Megure, now we can confirm it. According to Tatsumi Sakurako, after Ōba Satoru quarreled with Tatsumi Taiji, he took the elevator from the back door and left the floor where the video game company was located. And according to the situation of the buttons in the elevator, since there are no fingerprints of the deceased Ōba Satoru on the other buttons, it can only mean that the floor that Ōba Satoru went to should be the floor corresponding to the button that was deliberately wiped of the fingerprints.

"That is, the floor where the hotel rooms are located."

Regarding this point, if they had only realized that there was something wrong with that floor because the fingerprints were deliberately wiped off, then now, after the forensic department personnel have ruled out the fingerprints on other buttons that show traces of Ohba Satoru pressing them, they can only focus on that hotel floor.

Otherwise, where did Ohba Satoru go when he took the elevator from the back door?
Unless, when Tatsumi Sakurako returned to the company to look for Ohba Satoru, she did not look carefully enough, so that Ohba Satoru was hiding in the company and did not leave, otherwise the only destination that Ohba Satoru went to after leaving by taking the elevator could only be that hotel floor.

Previously, he thought that the fingerprints wiped off the elevator buttons were done by Vermouth in order to lead the police to the hotel room where he and Miyano Shiho had been hiding. Now, if Ohba Satoru went to that floor, then the meaning of the entire clue would be completely different——

Why did Ohba Satoru go to that floor?
After arguing with Taiji Tatsumi, Ohba Satoru left alone through the back door and went to the hotel floor. What did he want to do?
Could it be that he really rented a room on that floor? And Miyano Shiho and I were extremely unlucky, and the empty room we found happened to be rented by Ōba Satoru?

At this point, Gao Yuan couldn't help but think of the registration record of the hotel, and then said to Officer Megure:

"Officer Megure, go to the hotel lobby. I need to retrieve the hotel's registration records again!"

So, after hearing this, it was obviously meaningless for Inspector Megure. After all, at this point, any idea that Gao Yuan had would be good, as it was better than looking for a needle in a haystack without any clues.

So, just like that, Officer Megure agreed to Gao Yuan's request, took Gao Yuan back to the hotel floor, went to the hotel front desk, and asked the front desk to directly retrieve the registration information of the guest rooms on that floor in the hotel system -

Then, by retrieving the hotel registration information, I carefully looked at the registration information of the name "Oba Satoru" and found that the room corresponding to this name was registered tonight. Calculating the time, it was almost after I and Miyano Shiho hid in that room. In other words...

It looked like the room was booked specifically for him and Miyano Shiho.

But, if this is the case...

"Inspector Megure, when was Ooba Satoru's death?"

Suddenly, Gao Yuan asked this question - after all, it wasn't long since Ohba Satoru died, so it was not difficult to determine the exact time of death.

Therefore, judging from the time, this was completely after Ohba Satoru's death, and someone else rented the room here in the name of Ohba Satoru.

In this regard, after Gao Yuan raised this point and compared it with the time of Ohba Satoru's death, it can be basically concluded that -

Because even the registration time was after the police received the call from Sakurako Tatsumi. At this time, Ohba Satoru must have been dead, and it was impossible for him to check in to the hotel here.

"so……"

Looking at the newly discovered clues, Inspector Megure couldn't help but be surprised -

Such an obvious clue would not have been discovered if Gao Yuan had not come to check it directly in the system.

Obviously, if the room where "Miss Hayley" was found was chosen by someone pretending to be Ohba Satoru, then the person who chose this room was probably the one who threatened "Miss Hayley", that is...

The brown-haired woman who is suspected to be the murderer!
"This is the room the murderer booked!"

After realizing this, Inspector Megure hurriedly asked the hotel staff if she remembered what the person who booked the room tonight looked like.

In response to this, the staff member who was asked about this matter could only wave his hand with a wry smile and explained:

"This... happened just before my shift change, so I don't know... I have to ask the staff on my previous shift."

In this case, the staff member stated that she didn't know about this and could only ask the staff member before the shift change.

Inspector Megure was helpless about this and immediately asked his staff to contact the previous staff member, but even at this step, they were unable to contact that staff member.

So, at this point, the investigation seems to be stuck. Although there are some clues that may be related to the murderer, now...

"Can you tell us where that staff member lives?"

At this point, Officer Megure was helpless. He thought that after the other party changed shifts and went home, he should be able to go to the other party's residence to find her. Therefore, Officer Megure had to ask the staff about the residence of the staff member from the previous shift, and was ready to send police officers to her home directly to inquire without delay.

At the same time, Gao Yuan was concerned about another thing and continued to check the guest information on that floor.

After all, Ohba Satoru should have come to this floor of the hotel at that time. It is impossible that he came here without any purpose. So if that is the case...

Why did Ohba Satoru come here at that time? (End of this chapter)
