Stay away from Conan.

"Hey! Kudo, did you hear that!"

At this moment, on the other side, when Hattori Heiji and Conan got off Sakata Yusuke's car and ran towards Saito Apartment for a while, and were about to run to Saito Apartment, Hattori Heiji was stunned instinctively because he heard a loud noise from nearby, and asked Conan who was following him in surprise.

In this regard, Conan nodded very seriously, and then replied:
"Of course! It should be gunshots!"

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

"Yes, that's right..."

Hearing this, Hattori Heiji did not deny it, his expression looked very surprised but tried his best to restrain himself, and said:

"That was the sound of a gunshot, and the location is not far from where we are now..."

Saying that, Hattori Heiji thought about it solemnly, and then said:

"Kudou, Ms. Okazaki, you go and look at it first, as for..."

"Since that's the case, Ms. Okazaki, take it easy and go and see what happened to the gunshot just now!"

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

Hattori Heiji was taken aback by this—

"Kudou..."

However, seeing Conan's decisive look, Hattori Heiji gritted his teeth, and had no choice but to speed up his pace to follow, and with his high school student body, he ran much faster than Conan, and ran in front of Conan in a short while, as if he didn't want Conan to face the danger he might encounter alone in front.

In this regard, seeing Hattori Heiji's accelerated pace, Conan couldn't help but also quickened his pace, wanting to quickly see what happened to the gunshot just now.

So, when the two of them ran along the source of the sound just now, and came to a public restroom next to the Xidu apartment, they saw the scene where Otaki Goro was handcuffing Sakata Yusuke at the other side of the public restroom——

"Officer Otaki?"

Suddenly, seeing Officer Otaki appearing here, Hattori Heiji couldn't help being surprised for a moment, especially when he saw that the other party still handcuffed Sakata Yusuke——

Wait a moment?Why is Sakata Yusuke here?Didn't he just...

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

At the same time, in addition to Otaki Goro and Sakata Yusuke, the lady I originally planned to go to Xidu apartment to find, who was acting suspiciously at the scene of Noan Kazuto's fall, was actually here, and even...

"Mr. Wise?"

Strangely, seeing Gao Yuan appearing here, Conan who came to the scene couldn't help calling 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——

"Could it be that the murderer is..."

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

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 saying hello:
"Oh, Heiji, you're here too!"

"Officer Otaki, what's going on?"

Although there have been some guesses, Hattori Heiji and Conan still don't know the specific situation, so Hattori Heiji stepped forward and asked.

In this regard, after Otaki Goro handcuffed and controlled Sakata Yusuke, he was actually a little confused about the current situation. He turned to look at Takato next to him, and asked a little embarrassedly:
"Actually...Mr. Wise, I don't quite understand why the murderer is Sakata?"

Facing this problem, Gao Yuan took out of his pocket the copy of the graduation photo of the sleepover driving training class 20 years ago that he had taken from the Osaka Prefectural Police Headquarters, and handed it to Otaki Goro, and said:

"Look carefully, the coach's appearance..."

In this way, listening to Gao Yuan's words, Otaki Goro took the copy of the group photo handed over by Gao Yuan, and checked the photo of the coach who was believed to have died in an accident caused by drunk driving 20 years ago.

At the same time, Hattori Heiji also came up and looked at the photo Gao Yuan took out in puzzlement. As for Conan, because of his height, although he cared about the content of the photo, he really couldn't see it——

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

"Could it be that……"

Somewhat unbelievable, Otaki Goro said.

"Yes, that's right..."

Seeing this, he first heard Gao Yuan say "the graduation photo of the driving training class 20 years ago", and then noticed the reaction of Otaki Goro and others. Sakata Yusuke understood that Otaki Goro and the others had already seen the clues. So far, he confessed:

"For 20 years, Teji Inaba, the coach of the driving training class who was found to have caused his accidental death by drunken driving, is my father..."

At this point, after hearing the other party's own admission of this point, Otaki Goro, who already knew that this incident might be the murderer's revenge for the incident 20 years ago, basically understood the reason for Sakata Yusuke's murder.

"He is very careful when driving. Every time my mother and I ride in his car, he often tells my mother to check the rearview mirror inside the car. When he was a driving instructor, he was called a 'devil coach' because he was too strict..."

At this moment, knowing that nothing can be concealed, Yusuke Sakata explained the reason for his murder in a depressed mood:

"How can such a person drink and drive?"

Speaking of this, Sakata Yusuke seemed a little excited, and his body couldn't help shaking:

"And in order to find out the truth, I came here to become a criminal police officer... However, the statute of limitations for homicide is 15 years. After I finally figured out everything, as a criminal police officer, I have no choice at all..."

Saying that, Sakata Yusuke looked at Okazaki Sumie tremblingly and angrily at the side, which frightened Okazaki Sumie who had escaped from death again. Facing the son of Inaba Tejiji in front of him, Okazaki Sumie knelt down in fear.

In this regard, looking at the scene in front of him, Hattori Heiji noticed that in the photo taken 20 years ago, the three people who had been killed were all in the photo, and even Okazaki Sumie was also one of the people in the group photo. From this, based on the confession of Sakata Yusuke that he just heard, he knew what happened 20 years ago.

"At this point, let's go back to the police station and talk about it..."

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

But at this time, Gao Yuan suddenly said:

"Kiichiro Numabuchi... Where is he now? If I guessed correctly, he should be in your hands!"
