My neighbor's name is Conan

The police later discovered that a plastic model's right hand was missing in a storage room in the stairwell where old items were stored.

Aoki Matsu immediately thought of the gloved hand that Mao Lilan saw.

If that hand is really fake, and it is the hand of this plastic model, then Yusuke Nakamura is the murderer!

In addition, after Maori Ran left the lounge, Yusuke Nakamura did not move around extensively, because the guards on the basement floor did not see him come out, so the prosthetic hand was either on Yusuke Nakamura's body or on the basement floor.

Thinking of this, Qing Musong immediately asked someone to go to the basement floor to look for him.

Speaking of the guards on the B1 floor, Aoki Matsu just thought of a problem that he had not noticed before, that is, after Nakamura Yusuke and Mao Li Ran found the body in the lounge, why didn't they call the police or notify the guards on the B1 floor first, but asked Mao Li Ran to find Mao Li Kogoro.

This was a deliberate attempt to create a time when he would be alone in the lounge.

Aoki Matsu was somewhat accustomed to the fact that Maori Ran called the police and looked for Maori Kogoro when a murder occurred, but when he thought about it afterwards, it seemed wrong.

Even if Yusuke Nakamura was so frightened after discovering the dead body and subconsciously relied on the famous detective Kogoro Mori and forgot to call the police, he should have notified the guard on the basement floor!

After all, this is not just a simple matter of death, but the death occurred in this department store, so the person in charge of the department store should be contacted immediately.

Thinking about it this way, Yusuke Nakamura is indeed a very serious suspect.

And if it was him, it would make sense that the first murder scene was in the stairwells on the top floor and the eighth floor.

That is, when Watanabe Tomokiko went to find Sakamoto Yuki, she was seen by Nakamura Yusuke, so she followed Watanabe Tomokiko.

After Yusuke Sakamoto left, Yusuke Nakamura went up to question Tomoko Watanabe. The two sides did not have a good conversation, and then Yusuke Nakamura killed someone in a fit of excitement.

As for the other four, they were a little nervous about the time of killing.

Especially Yuki Sakamoto. If it were him, after killing someone, he could have placed Watanabe Yukiko's body on the floors below, or taken the stairs to the parking lot and transported the body out.

As for Aoki Shouta and his friends, although the three of them separated not long after, it was still about 10 minutes. Would Watanabe Yukiko wait here foolishly for 10 minutes? If she wanted to wait, wouldn't it be closer to go downstairs?

But there is still a question here - how was the body transported from the top floor to the stairwell on the eighth floor and then to the lounge on the underground first floor?

There was no sign of Yukiko Watanabe in the elevator, nor was there any sign of her being supported by someone else.

It is impossible to use fishing line in such a tall building, and there are no windows on the underground floor.

Combined with the marks on the left calf of the corpse, it is highly likely that the murderer put the corpse in something and transported it from the top floor to the basement floor.

Thinking of this, Aoki Matsu immediately remembered that the musical instrument was transported to the lounge by a kind-hearted person.

Did the murderer put the body in a box for musical instruments and then transport it down there? Some boxes for musical instruments are quite large, and there is no problem putting a slim woman in them.

As Qing Musong walked downstairs, he was thinking about checking the elevator surveillance video again himself.

When they got to the underground first floor and just got out of the elevator, before Aoki Song went to the monitoring room, Mao Lilan came over with a serious face and said, "Brother Aoki, I finally remembered the strange place!"

"Eh? Xiaolan, what did you remember?" Aoki Matsu asked.

Mao Lilan pointed to the round box at the door of the lounge and said, "That's the big drum. When I first saw it, the big drum was placed on this box, but now it's gone!"

Upon hearing this, Qing Musong immediately went forward to check, opened the round box, and found a big drum inside.

After feeling around for a while, Aoki Matsu felt that the round box containing the bass drum could easily hold a slender woman.

Taking out the big drum inside, Aoki Matsu immediately saw a square metal accessory on the round wall of the round box.

The size is exactly the same as the mark on the left calf of the corpse!!!

[The case is solved! Nakamura Yusuke is the murderer!] Aoki Matsu thought with a smile on his face.

The next step is to find evidence that Yusuke Nakamura is the murderer.

But this evidence is hard to find.

Yusuke Nakamura's method of killing was a bit inferior, and there were too many things wrong with it, but as for evidence, I haven't seen it yet.

Even if there were fingerprints on the round box, Yusuke Nakamura could easily argue that he stood on it when he was packing up his musical instruments.

No fingerprints or hair of Yusuke Nakamura were found on the victim, Yukiko Watanabe.

After thinking about it, Aoki Matsu could only check whether there was Yusuke Nakamura's fingerprints on the fake hand, and the surveillance video of the elevator to see if the person transporting the musical instrument could be confirmed to be Yusuke Nakamura.

Let Maruta Ayumi and others continue searching, and Aoki Matsu went to the monitoring room and asked the staff to retrieve the surveillance video of that time period.

The person who transported the musical instruments did appear in the surveillance video, but he was disguised and wearing the clothes and hat of a staff member, so it was impossible to tell who he was.

Aoki Matsu frowned when he saw this. At this time, Maruta Ayumi came over and whispered, "Inspector, we have searched the entire basement floor, but we haven't found the plastic model's prosthetic hand."

"Has the lounge been searched?" asked Aoki Matsu.

Maruta Ayumi nodded, "We searched it, but nothing was found. Do you want to search the entire department store?"

Qing Musong thought about it and shook his head, "No need."

Since it was not found on the underground floor, there are only three possibilities - on Yusuke Nakamura's body, in the musical instrument, or his reasoning was wrong.

Of these three possibilities, Aoki Matsu first checked the second one, which is the musical instrument.

Many musical instruments are quite large and can be used to hide things.

Aoki Matsu checked it personally, dismantled the drum set and other equipment, and checked each instrument one by one. Finally, when he picked up the guitar and shook it, he heard a different sound inside.

It looks like something was put inside the guitar.

There happens to be a hole on the guitar, which can indeed be used to place some small items.

Loosening the guitar strings, Aoki Matsu reached into the hole and took out a dummy left hand.

"It's actually in here." Maruta Ayumi was very surprised, and then he immediately picked up the flashlight fingerprint checker and shone it left and right at the dummy.

Judging from the materials, it is possible that fingerprints were left.

It depends on luck.

The police were apparently very lucky today.

"There are fingerprints." Maruta Ayumi said excitedly.

"Extract it immediately and do a fingerprint comparison." Aoki Song ordered.

"Yes!" replied the criminal from the forensic department nearby.

After Qing Musong handed the items to the criminal investigator of the forensic department, he walked into the conference room and said to the few people, "We just checked the stairwells on the top floor and the eighth floor and found that was the first murder scene. The lounge was not the first scene."

"What!" Everyone was shocked when they heard this.

Then Aoki Matsu said: "The green marks on the victim's shoulder are crayon marks. There are some children's paintings on the wall of the stairwell, and one of the paintings has traces of being heavily rubbed by something. It seems that Miss Yukiko was attacked there, and then the murderer pressed hard on the crayon painting and got crayon marks on her body."

"Then, why is the body in the lounge?" Risako Tanaka asked stupidly.

Qing Musong said, "The body was moved here later. There is a rectangular mark on the left calf of the body. After searching, we found that the mark is exactly the same as the metal fitting used to fix the handle in the box where the bass drum was placed. The mark on the left calf of the body is probably caused by the metal fitting."

Nishimoto Makoto felt that it was a bit far-fetched. "What did you say!?"

"What I mean is that Miss Yukiko's body was first put in this bass drum box and transported from the top floor to the door of the lounge. Then someone took the body out of the bass drum box and moved it into the lounge." Aoki Matsu explained, then looked at Nakamura Yusuke and asked, "Am I right, Mr. Nakamura?"

"Ah!" When they heard Aoki Matsu call out Nakamura Yusuke, Nishimoto Makoto and others were suddenly startled and subconsciously looked at Nakamura Yusuke.

Nakamura Yusuke also looked very surprised, and then asked in surprise: "Why are you asking me this?"

"Because you are the only one who stayed to help pack up the instruments. You are the only one who had the chance to put Miss Yukiko's body into the bass drum box!" Qing Musong looked at him and said, "Even if Miss Yukiko is thinner, she is still 40kg heavier than the bass drum. If a staff member moved the box, the inside would be exposed."

Nakamura Yusuke felt nervous when he heard this, and then he defended himself, "But, but when I used the key to open the door and entered the lounge, Yukiko's body was already inside, and Miss Maori also saw it! And after I packed up the instruments, I stayed with Mr. Maori and Miss Maori. How could I have time to move the body into the lounge?"

"No, you have time. I asked the staff when you finished packing the instruments, and they weren't sure, but they thought it was no more than 20 minutes. There is a margin of error of less than 5 minutes, which is enough time for you to kill someone and prepare the body.

As for what you and Xiaolan saw at that time, it was not the body of Miss Yukiko, but the hand of a plastic model. When you entered the room, you did not turn on the light at the first moment, which made the room very dark. In addition, you fell to the ground, blocking the way, so Xiaolan could not get close to the so-called corpse.

Therefore, what Xiaolan saw was only half of a hand wearing a glove. As for whether it was a real human hand, she couldn't tell it at all because of the dim light."

"So that's how it is. If it's just a dummy's hand, it would be easy to bring it in." Kogoro Mouri said with sudden realization.

Mao Lilan was shocked, but also reacted.

"At that time, I didn't bring in any dummy hand at all," Yusuke Nakamura defended forcefully.

Aoki Matsu looked at him and said, "Mr. Nakamura, we found the fake hand inside the guitar you were holding just now, and there are clear fingerprints on it.

You should have hidden the body in the bass drum box after killing someone, and then pretended to be a staff member to carry the instrument to the door of the lounge. Then you returned to the stairwell, hid the fake hand in the guitar, and went to the lounge with Xiaolan, and then you asked Xiaolan to wait outside the door.

He walked into the lounge first, took out the dummy's left hand from the guitar, placed a cushion and a blanket in advance to pretend that someone had fallen down, and added the dummy's hand to make Xiaolan mistakenly believe that it was Miss Tokiko who fell down there.

Then, while you were using Xiaolan to call Detective Maori over, you took advantage of that time to quietly move the box containing Miss Yukiko's body into the lounge, then took the body out of the box, put the gloves back on her hands, laid the body flat, and then covered it with a blanket, right?"

At this point, Nakamura Yusuke could no longer argue, so he confessed, "I killed Yukiko."

"Captain, why are you doing this?!" Nishimoto Makoto slammed the table excitedly again.

"This band is my life!" Nakamura Yusuke said with a gloomy face, "I thought it meant the same to you. I saw Yukiko and Mr. Sakamoto parting in front of the elevator, and I couldn't help but ask her if she and Shota were going to leave and join a new band...

That woman was kicked out of her previous band because she only thought about how to get noticed by the record company! She can still sing now, thanks to our support. But she arrogantly said that if it weren't for her, our band would have disbanded long ago! She also said that we can be the stepping stone for her official debut, and we should feel honored! "

Tanaka Risako was so surprised that she said, "Why is this happening..."

"I was filled with rage at the time, so I rushed over and strangled her neck. When I came to my senses, she was already dead." Nakamura Yusuke gritted his teeth and murmured in pain, "I have always believed that everyone has the same ideals, and I have always believed..."

Aoki Matsu shook his head in his heart. It was impossible to have an answer to the question about Nakamura Yusuke.

How should the other party answer this question?

Answering "yes" or "no" is not a good answer.

Because it would go against one's conscience.

Imagine if Yusuke Nakamura himself received an invitation from the company, would he choose to stay in the band or leave the band?

This kind of situation is not uncommon for bands, and it can even be said to be inevitable. Even groups that have already debuted have faced this kind of choice. Some choose to leave, some choose to persevere, and some even give up love.

Of course, an answer like that of Yukiko Watanabe is simply a suicidal answer.

Aoki Matsu sighed in his heart and said, "Mr. Nakamura, please go to the Metropolitan Police Department and explain the details to us."

Yoji Aihara stepped forward, lifted up the handcuffs that Yusuke Nakamura had put on him, and then escorted him away.
