My neighbor's name is Conan

"Hondou-san, why are you here?" Aoki Matsu asked Hondou Eisuke and the other three.

"We came here to sing karaoke after school," replied Hondou Eisuke.

Then Aoki Matsu led people to check the contents of Box No. 3.

"This musical instrument." Qing Musong saw a pair of maraschino on the coffee table, picked them up and shook them to weigh them.

The two loads together only weigh half a pound, which is completely incapable of achieving the effect of quickly hitting a person and knocking him to the ground.

"I like this thing too." Maruta Ayumi took a look and said with a smile.

Next is Box No. 4.

"Next is Mr. Youyuan from box 4." Aoki Matsu said.

Kenji Arimoto explained: "My girlfriend and I went to the gym and then sang karaoke. There's nothing wrong with that."

Aoki Matsu did not answer his question, but started searching the box.

At this time, Aihara Yoji suddenly found that the drink on the coffee table was a little different. He picked it up and looked at it and said, "This is a carbonated drink that was just launched not long ago, right?"

Arimoto Kenji replied, "Yes, my girlfriend wanted to try it and see how it tasted, so she bought it. But it was so unpalatable that she only took a sip."

"Eh..." Yoji Aihara took the drink bottle and looked at it carefully.

This is a 1L beverage bottle. If it is filled with liquid, it will be quite heavy.

Moreover, if carbonated drinks are shaken and left for a few seconds, the bottle will become very hard.

But the problem is that the air pressure inside will become very high. If it is subjected to external force at this time, especially a very strong external force, it is very likely to "explode" from the bottle cap and gush out.

Therefore, a carbonated beverage bottle is unlikely to be the murder weapon.

However, just in case, Aoki Matsu still asked the forensic detectives to test the bottle of carbonated drink and the microphones in several boxes with luminol reagent.

The microphone in the karaoke hall is neither too big nor too small, and it is heavy. It feels like a brick when you hold it, and can be used as a blunt weapon to kill people.

After searching the karaoke room inside and out, Aoki Matsu, Maruta Ayumi and others stood in the corridor to summarize the information.

"Inspector, all the guests' private rooms have been searched, but no murder weapon was found." Maruta Ayumi said with a frown.

Aihara Yoji also said, "Yes, we checked the restroom, but we didn't find the murder weapon."

"That's strange." Qing Musong frowned. "There are no windows in the entire karaoke room. After the murder, there is no place for the murderer to throw away the murder weapon. The murder weapon must be hidden in here."

"But we have searched everything, even the counter." Maruta Ayumi frowned.

Strange!

Aoki Matsu frowned and thought about it.

First of all, the victim must have been hit with a heavy object, not beaten to death by hand.

Secondly, there are no windows here, and the bathroom is also a secret bathroom. The murder weapon could not have been thrown out through the window, so it must still be here.

In the end, Mao Lilan and the others are definitely not the murderers.

Conan also ruled out the clerk's suspicion.

So now the only suspects left are: Kyota Honma, Kenji Arimoto, and Kunio Tamai!

Choose one of three classics!

The murder weapon cannot be found for the time being, so let’s first sort out the time when the three people went to the toilet.

17:50: Kyota Honma left the box to go to the bathroom.

18:03: Hondou Eisuke left the box to go to the bathroom.

18:04: Kyota Honma returns from the toilet. Kenji Arimoto leaves the box to go to the toilet.

18:07: Kunio Tamai leaves the box to buy cigarettes.

18:09: Tamai Kunio returns to his private room after failing to buy cigarettes. Arimoto Kenji returns from the toilet.

18:18: Hondou Eisuke comes back from the toilet.

That is to say, Kyota Honma went to the toilet for 14 minutes, Kunio Tamai went to the toilet for 2 minutes, Kenji Arimoto went to the toilet for 5 minutes, and Eisuke Hondou went to the toilet for 15 minutes.

The victim Mao Tingxun died between 17:50 and 18:20, within thirty minutes.

After seeing this statistical table, Aoki Matsu suspected Kyota Honma and Kenji Arimoto.

Kyota Honma was killed because he took too long to go to the toilet. Even taking a shit doesn't take that long. 14 minutes, this is more than enough time to kill someone.

Apart from that, there was a cigarette butt in the ashtray in his box, which was very strange.

In the case, any strange place may be a breakthrough, so Kyota Honma is now the biggest suspect.

As for Kenji Arimoto, it was because he brought his girlfriend with him. Generally speaking, especially in daily cases, the murderer would ask someone to prove his alibi, and some would be very smart to find Kogoro Mori. Apart from that, 5 minutes is enough to kill someone.

As for Kunio Tamai, he is much less suspicious because he is already 63 years old. The victim, Tatsumi Motoni, is 46 years old, much younger than Kunio Tamai and in his prime. But the victim died from multiple blows to the head with a blunt instrument.

If a conflict really broke out between Kunio Tamai and the victim, it is not certain who would beat whom.

Apart from that, 2 minutes is too short. Even if you don't have to clean up the body after the crime, you still have to check if there is any blood on your body.

After feeling that 2 minutes might not be enough to kill someone, Aoki Matsu checked if there was any blood on his body.

And there was a vending machine at the end of the aisle that sold cigarettes. If Tamai Kunio was the criminal, he wouldn't have to rush.

Of course, this is the idea of ​​an ordinary and normal person like Aoki Matsu. What if Kunio Tamai guessed the thoughts of someone like Aoki Matsu? That would be a big deal.

Therefore, Kunio Tamai’s suspicion cannot be completely ruled out, and now we can only say that he is the least suspicious.

If time is not enough to identify the murderer, then we will have to spend a lot of effort to find the murder weapon.

The murder weapon cannot disappear out of thin air. Even if it has wings, it cannot fly away in this environment.

But the police searched the entire karaoke hall and found nothing suspicious.

Moreover, this time, Aoki Matsu personally led the search, and there would not be a situation like the previous joint investigation of Section 2, where the police officers found clues but ignored them and did not report them. There would also not be a situation like the case of Okino Yoko, where such a large earring under the sofa was not discovered by anyone and Conan had to point it out.

The murder weapon could not have disappeared. Since it was impossible for it to disappear, yet it disappeared right under Qing Musong's nose, there are only four possibilities.

First, it was flushed down the toilet.

Second, it was something like ice that melted.

Third, it was something like a puzzle, which was disassembled into several large pieces and placed separately, so it did not attract the attention of the police.

Fourth, the murder weapon was hidden in a place that no one expected.

For the first and second types, Aoki pine can be directly excluded.

The toilet cannot flush away heavier objects that are slightly larger in size. If the murder weapon was ice, the wound would be different and could be recognized.

That leaves only the third and fourth possibilities.

After confirming these two possibilities, Aoki Matsu's eyes fell on the vending machine next to him.

Because Aoki Matsu suddenly discovered that vending machines perfectly fit both of these possible scenarios.

This vending machine has a key, and every day someone comes to open the door, add goods, and then take out the coins inside. The opening and closing process is not difficult, just like opening a locked cabinet, it doesn't take much time.

If the murderer had the key to the vending machine.

Then the murder weapon could be hidden in a vending machine, which is the fourth possibility.

In addition, vending machines accept coins, which are known to be small but relatively heavy.

If someone has a large bag of coins, can they be hit with that?

Thinking of this, Aoki Matsu looked at the vending machine and said to Maruta Ayumi, "Go call the vending machine manager and open the vending machine so we can check it."

"Ah!" Maruta Ayumi was stunned for a moment. "Inspector, are you going to search inside the vending machine?"

"Let me ask you, if the murderer has the key to the vending machine? Is it possible to hide the murder weapon in the vending machine after committing the crime?" Aoki Matsu asked.

Maruta Ayumi suddenly understood what was going on when he heard this. "Inspector, you are wise. This is really possible. I will contact them right away."

Conan, who was eavesdropping on the side, also instantly looked up at Aoki Matsu. He had not thought of this situation, but Aoki Matsu had already thought of it.

But it has to be said that this is possible.

Vending machine keys are not something particularly precious. If you are determined, you can get them.

At this time, a police officer came over with an evidence bag and said, "Captain, the film in the victim's camera has just been developed. One unexpected thing is..."

"Unexpected, what is it?" asked Aoki Matsu.

Qing Musong took it and looked at it, and was stunned.

The small camera was filled with photos of Mouri Ran and the other three, from the time they left Teitan High School to the time they entered the karaoke bar, but the center of the photos was not Hondou Eisuke, Mouri Ran, and Conan, but Suzuki Sonoko!

"What is this! Why are all of them our photos? How disgusting!" Suzuki Sonoko said angrily while looking at the photos with her hands on her hips.

Mao Lilan guessed fearfully: "Is he a stalker?"

"That must be it!" Suzuki Sonoko clenched her fists and said with a shudder, "Perverted stalker, so annoying!"

Among the suspects watching nearby, Kunio Tamai saw this and said, "It looks like this has nothing to do with us."

Honma Kyouta responded, "That's true."

Arimoto Kenji followed up with a complaint: "I haven't even seen what the victim looks like."

Hearing what Arimoto Kenji said, Aoki Matsu thought for a moment and asked, "Didn't you even have the chance to pass by the victim in the corridor?"

You Yuan Kenzhi replied: "Yes!"

"Even if I met them, it was at most in the corridor or the bathroom. I have only met these people who are here now," said Kyota Honma.

"I had never seen any other guests before this case happened." Kunio Tamai also said, but he suddenly said: "However, according to common sense, the murderer is the boy wearing round glasses, right?" As he said this, Kunio Tamai pointed at Hondou Eisuke.

"Ah!" Hondou Eisuke was stunned when he heard this.

Unexpectedly, Yuan Kenzhi echoed, "That's true. He got harassed by a stalker and killed him in a fit of rage."

"How is that possible?" Hondou Eisuke subconsciously defended himself.

Suzuki Sonoko was upset when she heard what Arimoto Kenji and the others said. She reached out and took a few photos from the table. She angrily walked in front of Arimoto Kenji and the others, put the photos and said, "Can you please look carefully? The central figure in every photo is me, right? His target is me, not this rustic boy with glasses!"

Suzuki Sonoko just felt that these people had serious problems with their eyes. Instead of taking pictures of such a beautiful and charming girl like herself, why did they take pictures of Hondou Eisuke, a rustic boy!

Although the victim's behavior was a bit disgusting, Suzuki Sonoko felt that the victim had good taste!

After being scolded by Suzuki Sonoko, Tamai Kunio was a little embarrassed. He turned to look at Aoki Matsu and said, "Officer, it's about time for us to go back."

"That's right, Mr. Officer." Honma Kyouta echoed, "It's already 7: now."

"No, you can't go back now." Qing Musong refused directly.

The vending machines have not been checked yet.

If the inspection reveals problems, it would be fine. If not, then it means that there is something wrong with Qingmu Song's idea of ​​solving the case, and he must think of another idea.

It is naturally impossible to let these people go back.

"I can wait until I prove my innocence before leaving," said Youyuan Kenzhi.

You Yuan Kenzhi, who seems to be the most difficult to talk to, is actually the most cooperative one.

"Please cooperate. If you are unwilling to cooperate, I have the right to force you to cooperate." Aoki Matsu said to Kyota Honma and Kunio Tamai.

Based on that surveillance video, Aoki Matsu also has the right to force the other party to cooperate for 24 hours.

Arimoto Kenji said indifferently, "Anyway, I just happened to have playing cards with me, so I can just play poker or Blackjack with my girlfriend to kill time."

Blackjack!

When Conan heard this English word, a light bulb went off in his head, and then the corners of his mouth curled up.

[I see, there is such a trick! ]

He has deduced the truth of the case.

and……

Conan looked at Aoki Matsu. He didn't expect that Aoki could find the target with his strong investigation-solving ability even though he lacked some information.

Therefore, Conan doesn't need to rack his brains to find a way to remind Aoki Matsu in this case.

In short, Aoki Matsu did not take the correct route because he was unaware of some circumstances, but the route he took still led him to the destination.

Afterwards, Conan was more concerned about why the victim was following them and whether the other party was from the FBI.

If this man's target wasn't Suzuki Sonoko...

The purpose could be to rob, rape, or blackmail?

On the other side, Aoki Matsu firmly refused to let the suspects go back and waited for the person in charge of the vending machines to come.

After waiting for a while, the other party came.

After Aoki Matsu showed the criminal warrant, he asked him to open the vending machine for the police to inspect.

The other party did as he was told, took out the key, walked forward, and opened the door of the vending machine, revealing the goods inside and the box of coins.
