Even the "one-stroke cut" by Inspector Matsumoto was so blurry because of the damage to his left eye that he couldn't confirm whether he hit the opponent's front or back.

If there was one clue, it would be the whistle, because the criminal always whistled a certain tune.

After that, through some reasoning, Conan found out the boy that the rich girl met at the beach.

It turned out that the other party had already known that the boy from that year was his current butler. After Conan's reasoning, the two of them happily recognized each other.

Among the two impostors, the man with a 30-centimeter scar on his back was brought back by Inspector Megure and his team.

The reason why he was able to determine whether it was the chest or the back was because of the text message sent to him by Kogoro Mouri (Conan), which helped him figure it out.

When people are injured, they will instinctively press their wounds, but no blood was found on the steering wheel of the vehicle abandoned by the criminal, which proves that Inspector Matsumoto hit the back which was out of reach.

Although the suspect tried hard to argue that it was not him, he explained that he had met a man with a scar on his back and thought it was cool, so he cut a scar on himself to imitate him.

And the man can also play popular songs from the 20s.

But Megure and the others would not easily believe the other party's one-sided words and let him go. Moreover, even if he was not the criminal, he had had contact with the suspected criminal, so they took him back to the Metropolitan Police Department.

After listening to Chiba's story, Karasawa automatically replaced Kogoro Mouri's actions with Conan, basically restoring the entire incident.

And this morning, they confirmed that the suspect's somewhat ridiculous reasons were actually true.

Because when he was 15 years old and that case happened, he had already gone abroad to live in a boarding school, and he had a clear alibi.

After spending a night in the cell, the man named Kusumoto Ryuhei confessed everything, even...

According to him, he and the man with the scar on his face met by chance in a sauna hot spring before leaving for boarding abroad.

The man had his head covered with a towel at the time, so Kusunoki Ryuhei did not see his face.

The man seemed to notice that Kusunoki Ryuhei was paying attention to the wound on his back, so he smiled and told him that the scar on his back was a medal of courage carved by a criminal five years ago, and asked him if he wanted to try it too.

And that Kusunoki Ryuhei actually did that. I don't know whether to say he was stupid, or that men are always young until they die, and that a middle school student thinks having a scar on his back is cool...

The reason why Inspector Megure and Chief Inspector Matsumoto paid so much attention to this case and even personally intervened is because this case is of great significance to them.

The criminal killed two people twenty years ago and one person fifteen years ago.

In addition, Inspector Morimura, the former partner of Inspector Matsumoto and the person who introduced Inspector Megure to the profession, died while investigating this case.

After Tang Ze learned about this case from Chiba, he knew that this was a serial murder case whose statute of limitations would expire in three days, and that new incidents would definitely occur within these three days.

If Conan had not been involved, Tang Ze still believed that the criminal might have been able to survive until the statute of limitations expired.

But now that Conan is involved, this might turn out to be a new murder case.

It was a pity that there was no plot to help him this time. He had no memory of this case at all, so now he could only rely on himself to solve the case.

After confirming that he had returned just in time to encounter an ongoing case, Tang Ze immediately asked for a file and checked the search information.

Here, the circumstances of this serial murder case are introduced in detail.

The first case occurred 20 years ago. The victim was Mr. Tsuguharu Boukawa, a 50-year-old doctor at the time.

As for the murder weapon, it was a katana that was in Tsuguharu Bogawa's own collection.

Two days after the other party was murdered, 42-year-old Assistant Professor Atsunori Mugita of the Department of Science and Engineering at Todoh University was murdered by the murderer using the same katana.

Because the murder weapons were the same, the police at the time merged the two cases and began to investigate this serial murder case.

That is, during the subsequent search process, when Officer Morimura, who was in charge of the investigation, saw a suspicious person passing by and went up to question him, he was hit by a fleeing vehicle that suddenly started and was seriously injured.

After that, Officer Matsumoto drove alone to chase the car, forced the criminal to the dock, and was ambushed by the vicious criminal and injured in the left eye.

The subsequent counterattack left a "straight cut" on the murderer's back. The criminal then escaped and took away the seat covers from the car to clean up the bloodstains.

Officer Morimura died from his injuries and was later promoted two levels to become Superintendent of Police.

The criminal escaped from the hands of Superintendent Matsumoto and remained silent for five years. He then murdered 34-year-old lawyer Susumu Nabei with a kitchen knife in his own home.

His method of committing crimes was to first use an electric baton to make the victim unconscious, and then use a sharp weapon to cut the body. His methods were extremely cruel.

Tang Ze also noticed that in these three murders, there were no signs that the door locks of the victims' homes had been pried open.

This naturally attracted the attention of the police at the time, but unfortunately, the investigation into the victim's acquaintances yielded no results.

The three people had nothing in common, and the search was at a standstill.

The reason why it was determined that the first two serial murders and the subsequent case five years later were committed by the same person was because the criminal left specific letters on the victims' bodies.
