My neighbor's name is Conan

Aoki Matsu looked at Shinji Fukamachi.

Without Aoki Matsu asking any more questions, Shinji Fukamachi knew that he was finished. His legs went weak and he knelt on the ground.

"I owed a sum of money, so I embezzled the production fee without permission. He found out and threatened me, so..."

So Shinji Fukamachi designed this mechanism in an attempt to kill Rikiishi Kengo once and for all.

Aoki Matsu looked at Shinji Fukamachi who was kneeling on the ground and ordered the police officer beside him: "Take him away."

Although the criminal was caught successfully.

But this case was still a little beyond Aoki Matsu's expectations.

Because the final murderer was not the three suspects who had exposed each other, but Shinji Fukamachi, who seemed to have no conflict with the deceased.

and so……

Science can only be used as a means to solve a case, not as evidence to solve a case.

Shinji Fukamachi's method of committing the crime was not at all sophisticated, but any responsible criminal could have solved the case.

Aoki Matsu felt no sense of accomplishment, and after returning to the Metropolitan Police Department, he left the follow-up matters to Maruta Ayumi.

but……

"Inspector." Aoki Matsu approached Inspector Megure and whispered, "Inspector, I think Maruta is ready to start his apprenticeship."

Although Aoki Matsu used Maruta Ayumi as a tool to close the case for free, he still had a conscience and was prepared to say a few good words for Maruta Ayumi.

Of course, this is also based on the premise that Maruta Ayumi is indeed able to patrol independently.

Inspector Megure thought for a moment and said, "He has been with you for so long, he is indeed ready to become your apprentice. Why, are you impatient with him?"

Aoki Matsu shook his head. "I just think that we can't delay him. With me by his side, the credit for solving the cases belongs to me. Saito is doing a great job now."

However, Kazuma Saito and Ayumi Maruta are different. Kazuma Saito is more of a technician who uses high-tech equipment, while Ayumi Maruta is more inclined to on-site police response.

This is also the reason why the two of them spent different lengths of time with Aoki Matsu.

Upon hearing this, Inspector Megure said, "I understand. I will arrange for Maruta to be in charge of some cases alone to see what he is capable of."

"Okay, Inspector, just keep this in mind." Aoki Matsu didn't say anything more after hearing this. The investigation of the three departments of the first division was all arranged by Inspector Megure, and it would be bad for him to intervene forcefully.

Anyway, what should be done has been done, and Qingmu Song believes that he has a clear conscience.

Aoki Matsu was in a good mood. Because Shinna Kohara went out of town to participate in an event, he returned to his parents' house and stayed for a day. Unexpectedly, when he woke up early the next morning, he saw a Western scene.

"Mr. Maori! Please hurry up!"

"Can't you run faster?"

Early in the morning, Kogoro Mori was running on the street carrying a fat woman on his back.

Conan seemed to be running in front of them holding something that looked like a cake box, and a young woman was following beside Conan.

"This is already the limit! Ms. Nitta, do you want to lose more weight?" Kogoro Mouri said, panting.

"What? What did you say? Is there something wrong with my hearing aid?" The fat lady selectively turned deaf at this time.

When Qing Musong saw this scene, he laughed like crazy.

【Hahahaha~】

However, seeing Kogoro Mouri and Conan like this, the fat aunt also looked familiar, and should be a resident living nearby, so Aoki Matsu hurriedly chased after her.

"Uncle Maori, did something happen?" Aoki Matsu asked.

"Someone was shot." Maori Kogoro answered while panting and carrying the aunt on his back: "They heard the gunshots and saw someone dead, so they asked me to solve the case."

"What!" Qing Musong's face changed drastically when he heard that, and he hurriedly followed them.

These two people were indeed residents of the neighborhood. After running for a while, led by the young woman in front, they arrived at a slightly shabby building.

"It's on this floor, inside, the innermost room." said the fat aunt.

Aoki Matsu and Maori Kogoro looked at each other.

Aoki Matsu nodded, Maori Kogoro took out a handkerchief, opened the door, and Aoki Matsu walked in first.

The scene inside scared everyone.

At this moment, the whole room was filled with butterflies, and there was a man sitting on the sofa in the living room, with his head tilted up and blood flowing from his mouth.

After seeing this, Qing Musong immediately walked in, grabbed the man's wrist and pressed it, then shook his head and said, "The man is dead."

Maori Kogoro also came over at this time, approached the sofa, took a look at the bloody cloth surrounding the man, and subconsciously said, "Remodeled pistol?"

"Let me tell you, Mr. Maori is a super famous detective. He will be able to solve the problem in no time." The fat aunt Nitta Hideko patted the woman next to her, Suzuki Yumi, and comforted her.

"Yawn!" Suzuki Yumi covered her nose and sneezed when she heard that.

"Are you catching a cold?" Hideko Nitta looked at her with concern.

Suzuki Yumi waved her hand, "No, I'm fine."

"People say that doctors often ignore their own health, so you must take care of yourself!" Hideko Nitta joked.

Suzuki Yumi smiled and shook her head and explained, "Really, I'm not a doctor. I just work in a dental clinic."

"Call the police!" said Aoki Matsu.

Not long after, Maruta Ayumi arrived with his people. Aoki Matsu and others started working only after they arrived.

The first person Aoki Matsu asked was Maori Kogoro: "Detective Maori, how did you meet these two ladies?"

"Uh! I was asked by Xiaolan to buy a cake on my way home. I ran into Ms. Nitta who looked nervous. I asked her and came here."

"Oh." Aoki Matsu looked at Nitta Hideko and asked, "Excuse me, Ms. Nitta, why were you so nervous at that time?"

"At 2:45 today, when I had just taken my daily nap, Ms. Suzuki came to see me. She came to give me a piece of toast, and while we were chatting, a sound that sounded like a gunshot came from Mr. Yamamoto's room.

But we didn't pay attention to it at that time, and then we went out. When we returned at three o'clock, we saw Mr. Nakanishi coming out of Mr. Yamamoto's room. I greeted Mr. Nakanishi, but he ignored me and didn't close the door.

When I saw it, I walked over and prepared to close the door for him, but I didn't expect to see this scene, which scared me so much that I fell to the ground. "When she said this, Nitta Hideko's face was full of fear.

Then Nitta Hideko said: "I have heard that Mr. Nakanishi and Mr. Yamamoto were very good friends, but even if Mr. Yamamoto really committed suicide, as a good friend, he ran away without calling the police or an ambulance. Isn't this strange?"

"Did he look like he was running away in a panic?" Aoki Matsu thought for a moment, then looked at Nitta Hideko and asked.

"That's right! There must be something wrong! Don't you think that no matter how you think about it, he can only be the murderer?" When Hideko Nitta said this, she suddenly became very excited.

Aoki Matsu nodded: "So he is indeed a very suspicious person. Maruta."

Maruta Ayumi understood and walked aside to make a phone call.

Then Qing Musong took the gloves and put them on, then began to inspect the scene, starting with the medical book on the coffee table.

Qing Musong picked up the suicide note and started reading it. "This is written to Mr. Nakanishi. It says that I can't pay the money back, so I want to die to apologize."

After reading the entire contents of the suicide note, everyone present frowned.

"This suicide note seems to have been typed by a word processor. There's no way to be sure that it was written by Mr. Yamamoto himself." Maori Kogoro reminded him, "The most wrong thing is~"

"He found the body of his best friend who he grew up with, and he just ran away without doing anything." Aoki Matsu took over what Kogoro Mori said.

It was such an obvious problem, but Qing Musong was not stupid, so he could see it at a glance.

After hearing this, Kogoro Mouri nodded in agreement, and Conan beside him also nodded in his heart.

This is indeed very strange.

"Based on my intuition as a former detective, the murderer is Nakanishi, who grew up with him. Affection is a very common debt problem." Kogoro Mouri folded his hands across his chest and expressed his opinion on the case.

However, the forensic doctor Tsujimura overturned Kogoro Maori's view the next second, "Detective Maori, according to the results of the autopsy, it doesn't look like homicide. The reason is that there is no sign of resistance on the deceased's body."

"No resistance at all!" Upon hearing this, Kogoro Mori widened his eyes in surprise.

Medical examiner Tsujimura nodded. "If someone put the gun in his mouth, there should be marks on his teeth, lips, and inside his mouth from resistance. Since we didn't find these marks, we can only assume that he opened his mouth wide on his own initiative."

Forensic doctor Tsujimura's words attracted the attention of Conan, who was flipping through an insect magazine nearby.

Qing Musong walked over to take a look, then nodded, "There is indeed no sign of resistance."

"No, but even if it looks like that," Kogoro Mouri insisted on his opinion.

Just when Maori Kogoro was about to express his opinion, Conan next to him interrupted him, "Uncle Maori! This butterfly is called the Red Knight Butterfly." Conan spread out the insect magazine, pointed to a pattern on it, then looked at the potted plant next to it and said, "This plant is called..."

Before Conan could finish his words, Maori Kogoro angrily picked him up and threw him out the door. "I don't have time to deal with these things now! Get out of my way, little brat."

At this time, Aihara Yoji, who was newly assigned by Inspector Megure to follow Aoki Matsu on patrol, came over and reported with a small notebook: "Inspector, according to the results of the comparison, Mr. Yamamoto was arrested for modifying a pistol.

According to Miss Suzuki who lives next door, he seems to be the type who will curse if you remind him that the TV volume is too loud, and is a person who only sees butterflies as the meaning of life.

"Inspector Aoki, I think such a strange man doesn't seem like the kind of person who would commit suicide because of the pain of debt." After hearing what Yoji Aihara found out from his investigation, Kogoro Mori still didn't think he died of suicide.

Aoki Matsu did not answer Maori Kogoro's words, but looked at Aihara Yoji and asked: "Aihara, what do you think?"

Aihara Yoji was a little excited by Aoki Matsu's questioning. After thinking seriously, he said, "Inspector, there is one thing I can't figure out. Ms. Nitta and the other two heard the gunshots at around 2:45, and Ms. Nitta saw Mr. Nakanishi come out of the room at around 3:00.

If Mr. Nakanishi is the murderer, then what was he doing in the room during the 15 minutes? If he is the murderer, he should try his best to escape from the scene as quickly as possible! "Yoji Aihara expressed the doubts he encountered during the investigation.

Qing Musong nodded and was quite satisfied. He was not a fool who could not see the obvious problems. "Yes, this is indeed a suspicious point."

"Inspector, Mr. Nakanishi is here." Maruta Ayumi came over and reported.

Behind him, Saburo Nakanishi walked in with his hands in his pockets, looking dissatisfied.

"Mr. Nakanishi, I think you also know that Mr. Yamamoto is dead. May I ask why you appeared here at that time?" Aoki Matsu looked at the other party and asked.

Upon hearing this, Nakanishi Saburo quickly explained, "He asked me to come, so I came at three o'clock as agreed. But when I entered the room, I saw Yamamoto dead on the sofa."

"So you found the body." Aoki Matsu looked at Nakanishi Saburo and continued to ask: "But he was your friend who grew up with you. Why didn't you notify the police immediately?"

"I'm the creditor who lent money to Yamamoto! I don't want to be misunderstood as killing him because of a debt dispute, so I ran away." Nakanishi Saburo said excitedly.

When faced with a threat to one's own interests, everyone will seek benefits and avoid harm and choose what is most beneficial to themselves.

At this time, the parties involved cannot distinguish right from wrong at all.

"No! Lying won't work. In order to avoid leaving fingerprints and gunpowder reactions, you wrapped the pistol in a towel, and at around 2:45, you put the muzzle of the gun into Mr. Yamamoto's mouth, pretending that he was committing suicide and shot him. There were two people nearby who heard the gunshot." Kogoro Mouri thought that Saburo Nakanishi was lying, and looked at him and reasoned.

"Then how do you tell me that I put the gun into Yamamoto's mouth? Is it possible that he would just open his mouth and wait for me to shoot him?" Saburo Nakanishi immediately started arguing with Kogoro Mori.

"It is possible that you deliberately waited until he yawned and then took this opportunity to take action." After saying this, Kogoro Mori nodded, thinking that what he said was absolutely right.

Nakanishi Saburo pointed at the dead man's body and shouted, "He was waiting for me to come and collect the debt. Do you think he would be in a leisurely mood to yawn with his mouth wide open?"

Maori Kogoro touched his head awkwardly when he heard this and said, "Ah, that's true."
