The famous criminal in Conan's world

Arriving at the monitoring room, the manager asked Bai Masong

"Officers, what time period do you want to check the surveillance?"

"When did the deceased check into the hotel? Bai Masong asked

"The four guests on the top floor all checked into the hotel around dusk, and it seems that they haven't left since they checked in."

The hotel manager thought for a moment and said

"Then pull up all the surveillance footage from the moment the deceased entered the hotel until you went upstairs to open the door."

Bai Masong said to the manager.

After receiving Bai Masong's instructions, the hotel manager immediately asked the security guard in the monitoring room to pull up the surveillance footage from the evening of this evening until he went upstairs.

""Okay, two officers, take a look."

The manager pointed to the surveillance screen and gestured.

Seeing that the surveillance was called up, Hakuba Song and Officer Megure lowered their heads and leaned over to look at the surveillance.

Originally, Hakuba Song was quite happy. After all, there was a surveillance here.

You know, surveillance in the island country is rarer than diamonds.

If there were more surveillance, Gin's habit of never covering his face would have made him wanted nationwide.

However, when Hakuba Song looked at the surveillance, he was disappointed.

Because there was nothing on the surveillance!

Yes, nothing.

From the time the deceased checked in until the manager went upstairs, only three people had left the elevator.

They were the residents on the same floor, Kinoshita, Hanai, and Koshimizu Nanatsuki.

Officer Megure looked at Hakuba Song with a confused look on his face and asked stutteringly,

"Brother Bai Ma, so the murderer must be one of these three people, right?"

"It seems so."

Hakumasong nodded, confirming the answer of Inspector Megure.

In his heart, Hakumasong couldn't help but sigh, very good, worthy of being a case in the Conan world, and a classic three-choice event.

After watching the surveillance, Hakumasong, Inspector Megure and the hotel manager returned to the top floor together.

As soon as Inspector Megure came back, he immediately cleared his throat, coughed a few times, and said to everyone,

"Now, my brother Bai Ma and I have made a major discovery, that is, from the time the few people checked into the hotel until the dead were found, no one had come up to this floor during this period of time!"

After hearing what Officer Megure said, Shiratori Renzaburo immediately reacted and said,

"In other words, the murderer is one of the residents on this floor?"

"So it seems that this is the case."

Inspector Megure said affirmatively.

The two people's statements were actually correct, but they caused dissatisfaction among some people present.

Kimura said impatiently,

"Always talking about the murderer, the murderer, but it is not certain whether there is a murderer or not! What if this uncle himself is so depressed that he wants to commit suicide, and then he makes such a secret room to disgust us all?"

Well, everyone does not agree with Kimura's words in their hearts. No one should be so stupid.

However, his words also reminded Inspector Megure and others that the problem of the secret room is the big problem!

You know, the island country also does the presumption of innocence. What does it mean?

It means that before anyone is convicted by the judiciary, he is still innocent.

Nowadays, the secret room cases are rampant, and there are also suspects who attempt to use the secret room to make the police presume that the deceased committed suicide.

Although no secret room has been sent to court before it was cracked, if it is really sent to court, judging from the judicial procedures of the island country, if a powerful lawyer is hired, the outcome is really unknown.

After listening to Kimura's words, Bai Masong narrowed his eyes and walked towards the room of the deceased.

The other policemen also They followed consciously. They might not be thinking about cracking the secret room. After all, they all had some self-knowledge.

However, even if they could help Bai Masong, it would be fine.

They couldn't just watch Bai Masong take them away.

The three suspects on the side also stood there consciously without moving.

In fact, Nanatsuki Koshimizu was still very interested in this secret room, but as a suspect, he could only watch.

Bai Masong once again entered the room of the deceased. This time he went directly to the bedroom. After all, this was where the deceased died, and it should be where the secret room was set up. Bai Masong looked at the surrounding arrangements, and gradually felt something was wrong.

The first was the knife that was inserted into the body of the deceased.

The knife was long. About thirty centimeters, this length is already quite long, not like the length of a dagger.

Such a knife, in theory, is not very convenient, because it is easy to be seen, not convenient to carry, and not concealed.

In this case, then why did the murderer use it?

Another suspicious point is the tape recorder, why does the tape recorder exist?

Yes, the existence of the tape recorder itself is a suspicious point.

You know, there are many types of secret rooms. In a sense, secret rooms are actually divided into two types: those that need to be discovered and those that do not need to be discovered.

Those that do not need to be discovered are like the secret room in the Shanni Temple.

The secret room of the Shanni Temple, once it was completed, it had already become a secret room, just like the monk Zhongnian two years ago. , even if it is discovered after several days, it can only be considered as suicide, because common sense cannot complete it.

It needs to be discovered, just like the bathroom murder case a few days ago.

Qingdao Quandai’s production is not a confined space at all, but it can use other people’s illusions to turn this bathroom into a secret room.

Today’s case also gave Bai Masong some similar feelings.

If this recorder is not used, the deceased can be found after they check out tomorrow, or the staff comes to clean up. Why bother?

Thinking of this, Bai Masong walked to the deceased, squatted down, and once again checked the key point of the secret room-the plastic bottle with the key.

This time, Bai Masong put on white gloves, picked up the plastic bottle, and checked it carefully.

Soon, Bai Masong found that the plastic bottle seemed to have been hit, and the bottle seemed to have some traces of frequent sliding.

Originally, Bai Masong heard Yueshui Nanatsuki say that this bottle was sold in the hotel, and thought that the murderer was just thinking about using local materials, but now it seems that this is not the case.
