"Hey! Kudo, you heard that! ”

At this moment, on the other side, when Hattori Heiji and Conan got out of Sakata Yusuke's car, ran a long way in the direction of the Nishito apartment, and were about to run to the Nishito apartment, because they heard a loud noise from nearby, Hattori Heiji was instinctively stunned, and asked Conan who was following him in surprise.

To this, Conan nodded very seriously, and then replied:

"Of course! This should be gunshots! ”

As soon as these words came out, Conan looked at Hattori Heiji with a very serious expression, as if asking his opinion.

"Yes, that's right......"

Hearing this, Hattori Heiji didn't deny it, his expression looked very surprised but tried his best to restrain it at this time, and said:

"That's gunshot, yes, and it's not far from where we're now......"

As he spoke, Hattori thought solemnly for a moment, and then said:

"Kudo, Ms. Okazaki, you go over and watch first, as for ......"

"In that case, Ms. Okazaki's side will take a slow time and go see what the gunfire just now is going on!"

However, before Hattori Heiji finished speaking, Conan had already made such a judgment, and after talking to Hattori Heiji, he turned around and prepared to run to the source of the gunshot.

In this regard, Hattori Heiji was stunned suddenly-

"Kudo ......"

However, looking at Conan's decisive appearance, Hattori gritted his teeth, and had no choice but to speed up his pace to keep up, and with his high school student's body size, he ran much faster than Conan, and after a while, he ran in front of Conan, as if he didn't want Conan to face the dangers he might encounter alone.

In this regard, looking at Hattori's quickened pace, Conan couldn't help but speed up his pace, wanting to quickly see what was going on with the gunshot just now.

So, when the two of them ran along the source of the sound just now and came to a public toilet located next to the Xidu apartment, they saw that at this moment, on the side of the public toilet, Otaki Goro was handcuffing the scene of Yusuke Sakata -

"Officer Otaki?"

Suddenly, seeing Officer Otaki appear here, Hattori Heiji couldn't help but be surprised for a while, especially when he saw that the other party still handcuffed Yusuke Sakata -

Wait a minute? How did Yusuke Sakata end up here? He didn't just ......

For a while, I just felt that the situation was a little unexpected, and Hattori Heiji didn't know what to say at the same time.

At the same time, in addition to Goro Otaki and Yusuke Sakata at the scene, Ms. Okazaki Chenge, who was originally going to the Xidu apartment to find and who was suspicious at the scene of Noyasu's fall from the building, is actually here, and even ......

"Mr. Wise?"

Strangely, seeing Gao Yuan actually appear here, Conan, who was then present, couldn't help but shout out his name for Gao Yuan in surprise, and then looked at the few people who appeared here, especially Yusuke Sakata, who was handcuffed, for a while, Conan's thoughts were also at a loss.

But soon, Conan and Hattori Heiji guessed something based on the current situation-

"It's hard to do it, the murderer is ......"

Surprised, both Hattori Heiji and Conan looked at Yusuke Sakata, and then guessed.

At the same time, Otaki Goro and Takato who were present also noticed the appearance of Hattori Heiji and Conan, so Otaki Goro couldn't help but greet:

"Oh, Heiji, you're here too!"

"Officer Otaki, what the hell is going on?"

Although there was some speculation, Hattori Heiji and Conan still didn't know what the specific situation was, so Hattori Heiji stepped forward and asked.

In this regard, after handcuffing Yusuke Sakata and controlling the other party, Goro Otaki was actually a little unclear about the current situation, turned to look at Gao Yuan beside him, and asked with some embarrassment:

"Actually...... Mr. Wise, I don't really understand why the murderer is Sakata? ”

Faced with this problem, Takato took out from his pocket a copy of the graduation photo of the driving class twenty years ago that he had taken from the Osaka Prefectural Police Headquarters, handed it to Goro Otaki, and said:

"Look at the ...... of the coaches."

So, listening to Takato's words, Goro Otaki took the copy of the group photo handed by Takato and looked at the photo of the coach who was believed to have died in an accident caused by drunk driving twenty years ago.

And at the same time, Hattori Heiji also came up, looking at the photo taken out by Takato in puzzlement, as for Conan, due to his height, although he cares a lot about the content of the photo, he really can't see it-

However, at this moment, after focusing entirely on the coach in the photo, Goro Otaki and Heiji Hattori, who had carefully looked at the photo, both showed surprised expressions, and turned to look at Yusuke Sakata who was handcuffed.

"Do you mean ......?"

It's a little hard to believe, said Goro Otaki.

"Yes, that's right......"

Seeing this, I first heard Takato say "the graduation photo of the driving class twenty years ago", and then noticed the reaction of Goro Otaki and others, Yusuke Sakata understood that Goro Otaki had already seen the clues, so far, he confessed:

"For twenty years, Tetsuji Inaba, the instructor of the driving class who was determined to have caused his accidental death due to drunk driving, is my father......"

At this point, after hearing the other party admit this in person, Goro Otaki, who knew that this incident might be the murderer's revenge for the incident twenty years ago, basically understood the reason for Yusuke Sakata's murder.

"He is very careful when driving, and every time my mom and I get in his car, he often tells my mom to make sure the rearview mirror in the car. When I was a driving school instructor, I was called a 'devil coach' because I was too strict......"

At this moment, knowing that everything could not be hidden, Yusuke Sakata was depressed and told the reason for his murder:

"How can such a person drive drunk?"

Speaking of this, Yusuke Sakata's emotions seemed a little excited, and his body couldn't help but tremble:

"And in order to find out the truth, I came to work as a criminal policeman...... It's just that the statute of limitations for homicide is 15 years, and after I finally figured everything out, I, as a criminal policeman, had no choice at all......"

As he spoke, Yusuke Sakata looked at Okazaki Chengjiang on the side trembling and angry, which made Okazaki Chengjiang, who had escaped death, frightened again, facing the son of Tetsuji Inaba in front of him, Okazaki Chengjiang fell to his knees in fear.

In this regard, looking at the scene in front of him, Hattori Heiji noticed that in this photo from twenty years ago, the three people who had been killed were actually in the photo, and even Okazaki Sumie was also one of the people in the group photo, and thus, based on the confession of Yusuke Sakata that he had just heard, he knew the events that happened twenty years ago, and at this moment, not only Hattori Heiji, but even Conan finally knew what was going on with this serial murder incident-

"Now that it's over, let's go back to the police station first......"

At this time, looking at Yusuke Sakata, who was trembling and sad at the moment, and Sumie Okazaki, who was kneeling on the ground, Goro Otaki couldn't help but say so.

But at this time, Gao Yuan suddenly spoke:

"Kiichiro Numabuchi...... Where are the others now? If I'm not mistaken, he's in your hands! ”
