I'm in Detective Conan, and the system has appointed Batman.

Because these people testify for each other, they all have alibis.

The police at the time felt it was impossible for all the trainees to collude to forge alibis, and thus concluded that Tetsuji Inaba had indeed drunk too much at the banquet, and ultimately died in an accident due to drunk driving.

But if it was these people who conspired to murder Inaba Tetsuji in the first place...

Hattori Heizo gently stroked his chin with his fingers.

He was pondering just how high the probability was.

But he immediately realized that his thinking was unnecessary, because sometimes it is not necessary to know whether there is such a possibility of the case developing, but only to know whether Sakata Yusuke will take action because of it.

Clearly, for Yusuke Sakata, mere suspicion was enough for him to commit murder.

This elite detective from the Osaka Police Headquarters has become increasingly irritable and efficient in his actions.

At first, he thought it was just a simple emotional instability or a more skillful way of doing things, but now it seems that he has probably realized the truth of what happened back then and wants to take revenge, hence the change in his mood.

Hattori Heizo's gaze fell on the police officer beside him, and he spoke earnestly.

"Please contact the police station near Sumie Okazaki's residence and have the officers there check on her situation... Tell them to go now, don't delay."

The police officer next to him was a little stunned, but still nodded.

Regardless, Hattori Heizo is the boss, so whatever Hattori Heizo says goes.

What neither the police officers nor Hattori Heizo noticed was that at that very moment, a drone employing optical stealth technology was hovering in the air above Goji Sotaro's residence.

Everything happening here, all the sounds, appeared precisely in Chen En's headphones and glasses.

He manipulated the drone to change its position, and then saw that the car of Hattori Heiji, Mori Kogoro, and others had arrived outside Goji Sotaro's residence.

Yusuke Sakata, an elite police officer from the Osaka Police Headquarters, was the first to get out of the car.

He was about to call Kogoro Mouri and Heiji Hattori to get off the car when he saw Heizo Hattori's gaze fall on him, and he immediately sensed something was wrong.

Before Sakata Yusuke could say anything more, Hattori Heizo asked directly.

"You were responsible for the three previous vicious serial murders, weren't you?"

This caught Sakata Yusuke off guard, and even Mouri Kogoro behind him was somewhat surprised.

He had met Hattori Heizo once before at the Nagato family villa, so he knew Hattori Heizo and knew that he was the head of the Osaka Police Headquarters.

Furthermore, through the high praise given to Hattori Heizo by many officers at the Osaka Police Headquarters, it was confirmed that Sakata Yusuke was indeed a capable police officer... However, the conclusion this officer reached was exactly the same as the conclusion he had previously reached incorrectly.

Could it be that he was right before, and that Sakata Yusuke is the murderer?

"...Captain Hattori, why do you say that?"

Sakata Yusuke frowned, as if he had been greatly wronged, and asked in return.

"What makes me look like a murderer?"

"Even if you are the head of the Osaka Police Headquarters, you can't say that about me. Even if I'm not an elite officer in the Criminal Investigation Department, but just an ordinary officer or even an ordinary citizen, such unfounded accusations are not too much."

"If you think I'm the murderer, then please provide the evidence."

"Without evidence, no matter how much reasoning is made, it's all castles in the air, and no matter how many accusations are made, they're all meaningless. I believe you, Minister Hattori, understand this better than I do."

The officers from the Osaka Police Headquarters who were standing nearby were also a little agitated at this moment.

They certainly trusted Hattori Heizo's judgment, but they also felt that Sakata Yusuke, as one of the most elite officers in the Osaka Police Headquarters, should not have committed such a series of murders.

Yusuke Sakata is quite young now and has a lot of potential for development.

Why would he risk his honor as a police officer and his promising future to commit a series of murders? What could have driven him to do such a thing?

"Mr. Sakata, you are the murderer. I think that doesn't need any further confirmation."

“Your understanding of this case far surpasses that of Inspector Ōtaki. As an officer who learned about the inside story of this case around the same time as Inspector Ōtaki, you shouldn’t know so much.”

Heiji Hattori leaned against the car, his fingers gently pinching the brim of his hat, which he had turned up.

Goro Otaki, standing next to him, just blinked in confusion, wondering why he was involved.

Then, Hattori Heiji continued speaking.

"You are the son of driving school driver Tetsuji Inaba."

"And if nothing unexpected happens, the last group of students that Inaba Tetsuji trained should be the murderers who killed Inaba Tetsuji himself, which would make up exactly six people."

"I had already noticed it when I was looking at the relevant information in the archives, and the email that just came from the Osaka Police Headquarters has made me even more certain of this..."

He spoke earnestly at that moment.

"Mr. Sakata, confess your crimes now."

"It's not too late to enumerate your sins now!"

Chapter 1182 In the Name of Revenge

"...So this is the message you received on your phone."

Sakata Yusuke finally realized what message Hattori Heiji had received in the car, but he didn't intend to give up. He simply asked in return, "What was it?"

"Even so, does that prove I'm the murderer?"

"And if I remember correctly, the case file concerning my father, Tetsuji Inaba, is closed as an accidental death, so there was no murderer, right?"

"How did you come to the conclusion that the person who killed my father, Tetsuji Inaba, was one of the victims of the recent serial murders? Wasn't the killer's motive to kill them to avenge Sotaro Goji?"

This was the initial reason Sakata Yusuke gave for wanting to find Goji Sotaro.

The three victims that can be investigated so far are all people who were forced to be used as scapegoats and dismissed when Goji Sōtarō was caught in a corruption scandal six years ago.

If we only look at these three people, it's clear that they are more likely seeking revenge against Goji Sotaro.

Logically, one shouldn't doubt him, as the most elite police officer in the Osaka Prefectural Police Headquarters, nor should one assume that he attacked those people to avenge his father.

But at that moment, a police officer rushed over from the side with a walkie-talkie.

He said, slightly out of breath.

"We've already investigated..."

"To be precise, the police officers from the police station near Sumie Okazaki's house were sent out to investigate. Sumie Okazaki wasn't home at all. We only found her when we searched the public restroom in the nearby park..."

"She is dead."

"The cause of death was the same as that of the previous victims: they were first strangled with a rope, then stabbed in the heart with a knife, which pierced their wallets and then their hearts."

Upon hearing this, even Yusuke Sakata was speechless.

If the previous three are related to Soutarō Goji and the embezzlement incident that occurred 6 years ago, then Sumie Okazaki has no connection with Soutarō Goji or anyone else.

She became a full-time housewife a year ago.

If, as Sakata Yusuke said, the murderer assassinated someone connected to Goji Sotaro, then Okazaki Sumie shouldn't have been a victim.

But in the end, Sumie Okazaki died in a public toilet in the park.

"...Mr. Sakata, I have to tell you that the only connection between these people, if we include Sumie Okazaki, is only one."

Hattori Heizo spoke calmly at this moment.

"That was the driving school back then."

"They were classmates at driving school, trained under Mr. Tetsuji Inaba, who was known as the devil instructor. Apart from that, they had different identities, different jobs, and no other connection."

"No matter how bizarre something seems, if other possibilities are ruled out, then it can only be true."

"Now that things have come to this, do you really still think you did something completely flawless?"

“I guess Okazaki Sumie was invited out by you after receiving a phone call. If that’s the case, as long as we trace the source of all of Okazaki Sumie’s phone numbers and confirm that you are among them, the suspicion of murder will be established.”

"Then we will further check whether the nearby car rental companies have your vehicle rental record."

"If we only need to determine whether there is any information about you in the rental records from the day before Okazaki Sumie's death to the present, and then find eyewitnesses about the distance between Okazaki Sumie's house and the public toilet..."

"I must say, you are quite an excellent subordinate of mine, but you are not quite qualified as a criminal."

He estimated that Numabuchi Kiichiro, who has been missing ever since, was also inextricably linked to Sakata Yusuke.

If there is indeed a connection, she will most likely play the role of a scapegoat in Sakata Yusuke's plan, taking the blame for the murder.

In response, Hattori Heiji, who was standing next to him, added something.

"Just as your father said, you still have some weaknesses."

“Brother Sakata, as an elite officer of the Osaka Police Headquarters, you have a lot of things to deal with every day, but today you put aside other things and used your paid leave to be my driver.”

"Actually, it was to use my existence to guide me to investigate Goji Sotaro."

"Then, as a police officer investigating alongside me, I can naturally enter Goji Sotaro's mansion and find an opportunity to take revenge on Goji Sotaro, the last person to harm your father?"

"In that case, it's not surprising that the body landed squarely on that new police car."

"Because you are the murderer who killed that person, you know exactly where the body will fall, so you parked the car there beforehand and lured me into this incident."

Hattori Heizo and his son Hattori Heiji gradually pieced together the situation through their conversation.

The councilor, Sotaro Goji, is still hiding in his residence and refuses to come out, and he also refuses to contact the officers of the Osaka Police Headquarters. He probably thinks that Yusuke Sakata, who looks very much like the deceased Tetsuji Inaba, is suspicious.

Otherwise, even if it's due to the corruption case six years ago, it's not normal to be so afraid of contacting the police.

With things having come to this point, Sakata Yusuke naturally had no room for further arguing.

He paused for a moment, then spoke.

"Even so, you don't have any solid evidence to prove that I killed the person, do you?"

"But even if it's just suspicion to this extent, my plan has completely failed. After all, in this case, I can no longer contact Councilor Sotaro Goji as a police officer of the Osaka Police Headquarters."

Sakata Yusuke then spoke in a low voice.

“I don’t know where Numabuchi Kiichiro is now either. His disappearance is indeed unrelated to my plan.”

"However, I'm still somewhat surprised that you, Minister and Hattori, were able to see through all my plans so quickly, before I could make my final move..."

"Now that things have come to this, I have nothing left to hide."

"Having been investigated to this extent, even if I deny everything, I'm finished."
