My neighbor's name is Conan

This means that there was financial dealings between the company where Akio Nishimura worked and Ryozo Gamo's company.

Qing Musong felt more and more that his guess was correct.

However, it is not completely certain whether the loan was facilitated by Akio Nishimura. What if it was just a coincidence?

So after Aoki Matsu left someone at the apartment, he took the two people to the company where Akio Nishimura worked.

There's no way. Akio Nishimura is still at work and hasn't gotten off work yet.

When he arrived at the company where Akio Nishimura worked, Aoki Matsu did not go to find him first, but went directly to the company's manager to ask about the matter.

The company manager was somewhat surprised that a criminal would ask about the loan from five years ago, but he still answered, "At that time, the company was short of cash, so it borrowed some money from Haraiso Financial Company to make ends meet. It was indeed Nishimura-san who facilitated this. I heard that he had a good personal relationship with Mr. Gamo. Because of this, Nishimura-san was promoted to department manager."

Upon hearing this, Aoki Matsu asked the company manager to call Nishimura Akio over.

Soon, Nishimura Akio arrived at the company manager's office. Aoki Matsu showed Nishimura Akio the criminal certificate, then looked at him and asked, "Mr. Nishimura, do you remember five years ago when you provided an alibi for Mr. Gamo at the Josai Police Station?"

Nishimura Akio's face changed when he heard this, but he still replied: "Of course I remember, what's the matter?"

"Mr. Nishimura, was Mr. Gamo really with you five years ago?" Aoki Matsu asked, staring at Nishimura Akio.

Nishimura Akio looked a little unnatural, but he said, "Of course, Mr. Gamo did drink with me five years ago."

Five years ago, the police didn't find any problems. Five years later, there is no evidence at all. What evidence can the police find?

Aoki Matsu naturally understood what Nishimura Akio was thinking. He looked at him and said, "Mr. Gamo was murdered last night. It was obviously a revenge killing."

"What!!" Nishimura Akio was shocked and his face turned pale.

Five years ago, he dared to give false testimony for Gamo Ryozo, on the one hand because of personal interests, and on the other hand because Gamo Ryozo's crime was not serious. He just beat someone but did not kill the person.

But if that matter involved human life, especially his own life, Nishimura Akio would feel a little panicked.

"Mr. Nishimura, let me ask you one more question. Did Mr. Gamo drink with you five years ago?" Aoki Matsu said to Nishimura Akio with a stern face.

Nishimura Akio was very panicked, but he still denied it. After all, perjury is against the law. If it involves a murder case, he will bear the corresponding legal responsibility. "I did not perjure myself. Mr. Gamo was drinking with me five years ago."

lie!

Aoki Matsu could tell at a glance that Nishimura Akio was lying.

But just as Nishimura Akio had thought before, Aoki Matsu had no evidence and there was nothing he could do to Nishimura Akio.

The 24 hours of forced cooperation are not enough to meet the murderer who is seeking revenge for his wife. People have plenty of patience.

So when he saw that Nishimura Akio refused to admit it, Aoki Matsu didn't insist and just led him away to another address.

That’s right, there were not just one person who testified for Gamo Ryozo, but three people.

That is why the West City Police Station released the person.

The second person is a bar security guard named Shoichi Fukuda.

Five years ago, he was still a street thug. It is said that he almost hit Gamo Ryozo's car when crossing the road. Gamo Ryozo cursed him and he even spat at him.

Facing Aoki Matsu, Fukuda Shoichi also refused to admit that he had given false testimony five years ago.

But after Aoki Matsu's investigation, he found out that the bar where the other party worked also had financing and loan business dealings with HARAISO Financial Company.

The third one was an old man, but he passed away last year.

Both witnesses said that they did not commit perjury, and Aoki Matsu really couldn't do anything to them, so he went back to the Metropolitan Police Department.

Of course, Aoki Matsu didn't really ignore the two of them, but sent people to monitor/protect them secretly.

After returning to the Metropolitan Police Department, Aoki Matsu immediately went to the interrogator to ask for the interrogation records of Kyosuke Arai.

According to Kyosuke Arai, he was at home at that time last night, drawing illustrations for a weekly serial novel. But there were no witnesses, and he lived alone.

Kyosuke Arai did not deny that he had borrowed a lot of money from people everywhere.

But as for the words that the inheritance would belong to him after Gamo Ryozo's death, Kyosuke Arai firmly said that he said it when he was drunk and he had no intention of killing his uncle.

In short, although there are many clues and evidences that are unfavorable to Kyosuke Arai, Kyosuke Arai firmly denies that he committed murder.

"Have you found out what I asked you to investigate?" Aoki Matsu looked at Maruta Ayumi and asked.

Maruta Ayumi nodded. "I found out that Mrs. Takeoka fell ill two years ago and passed away last month. I also asked the medical staff at the time and heard that Mrs. Takeoka did occasionally say that she was sorry for Mr. Takeoka."

【Done! 】

Aoki Matsu sighed when he heard this.

It is very likely that Isao Takeoka is the murderer.

However, due to the special nature of Takeoka Isao's previous career, Aoki Matsu could not tell him directly.

Because Aoki Matsu is in office now, it would have a bad impact to suspect a former police officer without any evidence.

Moreover, Aoki Matsu had to admit that he did not find any evidence in Gamo Ryozo that identified Takeoka Isao.

Now Aoki Matsu believes that Takeoka Isao is the murderer, but in fact he has no evidence at all. It's all based on scientific research, but scientific research sometimes fails.

Unfortunately, Takeoka Isao is a former policeman with certain anti-detective abilities, so it would be difficult to find evidence.

After thinking about it, Qing Musong could only use that one trick - fishing enforcement.

Kyosuke Arai was released, but someone was secretly monitored/protected, so that when Takeoka Isao committed another crime, he could be caught red-handed.

There were five parties involved in the case five years ago. From the perspective of the murderer in the scientific world, he would never stop until he killed all five of them.

Of course, maybe scientific research failed this time, and Takeoka Isao was not the murderer, so the sting operation was useless.

Therefore, while Aoki Matsu sent people to monitor Kyosuke Arai, Akio Nishimura, and Shoichi Fukuda, he was also still investigating the death of Ryozo Gamo.

After careful investigation, nothing was found except a set of footprints found on the ground near the bathroom outside Ryozo Gamo's villa.

This set of footprints should be the result of the murderer monitoring Ryozo Gamo and looking for an opportunity.

But... Aoki Matsu can't possibly ask everyone in Tokyo to have their footprints checked!

Even if we can use footprints to infer the other person's gender, age, weight and height, the range is too wide.

Moreover, this set of footprint inspection is mainly used and recognized by flower growers. Other countries think it is a bit mysterious and unscientific, so to some extent they do not recognize the results of the footprint inspection.

As for Kyosuke Arai, the female neighbor who lived next to his house could help him prove that he was at home at the time.

According to the testimony of the female neighbor, she heard a loud noise coming from Kyosuke Arai's room at about 8 o'clock, so she went to the balcony to talk to Kyosuke Arai and ask him to keep his voice down. Then she saw Kyosuke Arai walking around the room with a piece of paper and shouting, but he soon quieted down, so she didn't say anything.

It takes an hour and a half to drive from Arai's house to the woods where the crime occurred.

The female neighbor saw Kyosuke Arai at around 8 o'clock.

In other words, Kyosuke Arai could not be the murderer because there was not enough time.

Kyosuke Arai was cleared of suspicion, but there were no other clues in Gamo Ryozo's case except for the footprints.

Fortunately, Aoki Matsu understands science.

The next day, for some reason, Takeoka Isao teamed up with Mori Kogoro and went to find Kyosuke Arai.

Then that night, he went to Kyosuke Arai's house alone to find him.

This time, when he went to find him, Takeoka Isao wanted to kill him and avenge his wife.

However, he didn't expect that Aoki Matsu had already sent people to secretly monitor/protect Kyosuke Arai, so when he just strangled Kyosuke Arai's neck with a rope, he was caught by Aoki Matsu.

"Mr. Takeoka, I didn't expect it was you." Aoki Matsu sighed as he looked at the captured Takeoka Isao.

In fact, Aoki Matsu really hopes that science will fail this time, after all, this is a sad story.

Takeoka Isao looked at Aoki Matsu in shock and asked, "Why do you think I'm the murderer?!"

"I asked Mr. Hisamoto and learned that your wife had passed away and was feeling guilty before her death, so you had enough motive to kill Mr. Gamo. To be honest, I didn't have any evidence before. I was waiting by Mr. Arai's side, just waiting for the murderer to fall into my trap." said Aoki Matsu.

Aoki Matsu has no evidence.

After saying that, Aoki Matsu looked at the frightened Arai Kyosuke and asked, "Mr. Arai, in that case five years ago, you paid to hire a witness to prove your innocence, right?"

Kyosuke Arai had just escaped from the brink of death and was terribly frightened. He had never expected that the case five years ago would make people want to kill them. In Kyosuke Arai's mind, it was just that his uncle had beaten someone up, and the crime did not deserve the death penalty!

So he was so frightened that he answered directly to whatever Aoki Matsu asked, "Yes, when my uncle was arrested, he asked me to hire a witness, and then my uncle was released from the police station."

"Takeoka-san, you must have learned the reason why Mr. Gamo attacked Mr. Kinugasa after Mrs. Takeoka died, and that Mr. Gamo paid someone to give false testimony for him. You believed that Mrs. Takeoka's death was partly due to the guilt you felt for resigning from the case, and that's why you hated Mr. Gamo and the others."

Isao Takeoka looked at Aoki Matsu and said, "That's right, I killed Ryozo Gamo. Inspector Aoki, you are much better than me. If it were five years ago, I could have investigated the matter as clearly as you did, maybe Natsuko would not have..." As he said this, tears fell from Isao Takeoka's eyes.

He was not crying because he regretted being caught, but because he was crying for his wife.

"Take them all back to the Metropolitan Police Department, including Akio Nishimura and Shoichi Fukuda," Aoki Matsu ordered.

Since Takeoka Isao killed someone, he should naturally be punished by law, but because Aoki Matsu stopped him in time, he only killed one person, and it was revenge for his wife. There is enough emotional consideration, so he may only be sentenced to five to ten years.

As for Kyosuke Arai, Akio Nishimura and Shoichi Fukuda, the three of them gave false testimony, which led to a police officer resigning. Later, one of them was killed and another died of depression.

Two lives, one life.

This already involves criminal matters, and they will be punished by law.

The only thing that Aoki Matsu didn't expect was that Takeoka Isao was certain that Gamo Ryozo paid someone to give false testimony after he saw media reports on Kinugasa Ei's death, because it happened to be the last day of his wife's funeral and he drank some wine.

After getting drunk, Takeoka Isao called Gamo Ryozo directly and said, "Don't tell me it wasn't you who did it? Just like the night raid five years ago."

In fact, Takeoka Isao was just drunk, but unexpectedly, Gamo Ryozo replied, "This, it really wasn't me who did it this time." Then Gamo Ryozo hung up the phone.

When Takeoka Isao heard what Gamo Ryozo said, he sobered up immediately, because Gamo Ryozo's words were completely self-incriminating.

“Not this time” means that he was the one who did it “last time”.

So Mrs. Takeoka's testimony was not wrong.

Then Takeoka Isao turned evil.

He felt that his wife told the truth but was not believed, and even apologized to him before she died. He had to seek justice for his wife.

If the police can’t give it to him, then he will do it himself.

Moreover, Takeoka Isao hated himself for not being able to find out the truth at that time, which caused his wife to be upset. So he had already made up his mind that after sending Gamo Ryozo and others down, he would also go down to accompany his wife.

Aoki Matsu sighed when he heard this.

What a tragedy.

Sometimes being too powerful and too rich is not a good thing.

In fact, even if Gamo Ryozo had pleaded guilty five years ago, it was only assault, a minor crime. In addition, he was already in his seventies at the time, so he might not have gone to jail.

I just didn't expect that Gamo Ryozo didn't want to go to jail and paid someone to give false testimony, and then he was so aggressive that...

Aoki Matsu was able to solve this case thanks to scientific research.

So Maruta Ayumi is really unlucky.

His next independent case will be postponed again.

Moreover, if Maruta Ayumi is so unlucky again next time, it will be difficult for him to handle cases independently in his lifetime.

Even though the Metropolitan Police Department talks about science and evidence every day, people are actually quite metaphysical about some things, such as luck.

No one wants to work with someone who is unlucky.

Maruta Ayumi himself felt that he was a bit unlucky. Why did the cases he handled become so complicated and difficult afterwards? The key point was that this was not intentional on the part of Inspector Megure.

Every year, the Investigation Division handles several cases of bodies being found in parks.

Qing Mu Song had handled a case like this before, and it was easy to solve, but now it was his turn...

It's really depressing.

In order to comfort Maruta Ayumi, Aoki Matsu deliberately called a few colleagues and took Maruta Ayumi to the bar for a few drinks.
