Stay away from Conan

"Headmaster?"

Hearing this title read out from Otaki Goro's mouth, Gao Yuan couldn't help but look very surprised:

"Hattori Heizo, Hattori Heiji's father? Why do you want to see me?"

The head of the Osaka Prefectural Police Headquarters, Hattori Heiji's father, police supervisor Hattori Heizo.

However, as the top leader of the Osaka Prefectural Police Headquarters, apart from knowing Hattori Heiji, I can be considered to be connected with him. Other than that, I really can't think of any reason for the police inspector to name him.

And obviously, just knowing Hattori Heiji was not enough for the police inspector to ask Officer Otaki to pick him up as soon as he arrived in Osaka.

In this regard, Gao Yuan couldn't help asking this question.

Otaki Goro did not explain immediately, but just motioned for Gao Yuan to follow him and said:

"Mr. Mingzhi, time is limited, let's chat in the car."

With that said, Otaki Goro walked forward and asked Gao Yuan to follow him.

So, although he felt that things were a bit strange, since it was Otaki Goro who came to pick him up, he had no reason to refuse. Thinking that the Osaka Prefectural Police might have something to do with him, Gao Yuan took Xiao Ai and walked out of the station together. Under Goro's guidance, he got into Otaki Goro's private car parked outside the station——

"Huh? By the way, Mr. Mingzhi, who is this child?"

Seeing Xiao Ai following Gao Yuan, and thinking about how he was still alone when he met Gao Yuan last year, Otaki Goro asked curiously.

"She's the sister of a friend of mine."

Facing the inquiry, Gao Yuan naturally answered with the words he was accustomed to saying for a long time. Then after sitting in the back seat with Xiao Ai and Otaki Goro started to start the vehicle, Gao Yuan asked:

"By the way, Officer Otaki, what happened? Why did the Hattori Police Supervisory Committee want to see me? Also, were Mr. Mori and the others called over too?"

After thinking about it carefully, I arrived in Osaka a few hours later than Mouri Kogoro and the others. It is possible that, with Conan and the others in the same situation, they might have encountered some incident by chance, so in the face of such a situation, for the late If I take a step forward, it seems to make sense that Officer Otaki and others will come to pick me up.

So, based on this idea, Gao Yuan asked.

However, Otaki Goro's next answer denied this possibility——

"It is true that an incident happened. It was just Mr. Akechi who was invited by the head of the department. Mr. Mori and the others should be visiting Osaka with Heiji and the others right now..."

Otaki Goro said a little seriously, and seemed a little apologetic, and couldn't help but add embarrassedly:

"So, Mr. Akechi is also a guest invited by Heiji. But before you could come and have a good time, we came to take up your time immediately. I'm really sorry..."

"No... Since I bothered Inspector Hattori of the Osaka Prefectural Police Headquarters to invite me, it must be that a very important event happened, right? And he only invited me but not Detective Mori who came one step earlier than me... because of the incident. Is it related to me?”

Listening to Otaki Goro's words, Takato thought for a moment and then replied, feeling that the incident mentioned by Otaki Goro seemed a bit unusual——

"It is indeed an important case, and it does have something to do with Mr. Akechi..."

Otaki Goro did not deny this, and then said:

"Well... let me think about it, let's explain it from the beginning!"

As he said that, Otaki Goro slowly told about the recent murder incident in Osaka Prefecture——

"Half a month ago, a murder occurred in Toyonaka City. The deceased was a middle-aged man named Nagao Hidetoshi, who was a convenience store manager. The place where he was killed was from where he worked. He was found in a park on the way from the convenience store to his home. There were no witnesses. The cause of death was that he was stabbed in the heart with a short knife. Currently, no suspicious suspects have been found. ”

Seriously, Otaki Goro said.

In this regard, listening to Gao Yuan's story, I couldn't help but feel a sense of déjà vu——

"Pierced through the heart with a short knife..."

Muttering, Gao Yuan expressed interest in this point.

"That's right."

Nodding, Otaki Goro continued:

“The local police station conducted a serious investigation, but was still unable to solve this incident... And last week, another similar murder occurred in Hirakata City——

"The deceased's name was Nishiguchi Tashiro, and she was the proprietress of an izakaya. She was also attacked on her way home after get off work at night. She was stabbed through the heart with a short knife and died. There were no witnesses..."

"Serial murder case?"

Listening to Otaki Goro's statement, Gao Yuan couldn't help but ask:

"Aside from the fact that the deceased was stabbed through the heart with a dagger, what else do the two incidents have in common?"

"some!"

Nodding, Otaki Goro seemed surprised by Takato's sensitivity and immediately replied:

"I don't know why, but the short knife penetrated the wallets in the pockets of the two people's jackets and pierced their hearts! Regarding this point, after the first incident, we did not announce the details of the wallets to the public, so the second incident The two incidents are unlikely to be the result of imitators, they should be the same murderer!"

Sighing a little, Otaki Goro continued:

"However, there were no witnesses to the two incidents, and the locations were more than ten kilometers apart. We are currently filtering the interpersonal relationships of the two victims, but no common ground has been found, so the investigation of the incident has been in a stalemate..."

"In both incidents, the knife the murderer stabbed into the deceased's heart first penetrated the deceased's wallet. So what was in the wallet?"

After hearing this, Takato was basically convinced that this was an original incident that he knew about, but he still didn't know the reason why Hattori Heizo came to him——

"Mr. Akechi, you are so perceptive!"

At this moment, when Gao Yuan mentioned the contents of his wallet, Otaki Goro was completely surprised, and then he couldn't help but say:

"The police investigating the two murder cases separately investigated the two murder cases for a long time, but found nothing. Finally, because of the possibility of serial killings, after the files of the two murder cases were handed over to the headquarters today, the head of the department and the director of Toyama immediately pointed out Then we found that the driver's licenses of the two deceased people were in their wallets. Therefore, under the instructions of the director, we immediately conducted a detailed investigation into the matters related to the driver's licenses of the two deceased people. Twenty years ago, before they obtained their driver’s licenses, they all attended a residential driving class in Hyogo Prefecture!”

Speaking of this, Otaki Goro's expression looked very serious——

"In addition, we also found out that on the day the two deceased persons graduated from the driving training class they attended twenty years ago, an instructor in the driving training class died due to drunk driving! In this regard, we realized that this The serial killings may be related to this incident that year...

"This time, the reason why the minister plans to invite Mr. Akechi... We found out that among the people who attended the shared driving training class with the two deceased people, there was another extremely dangerous person——

"Numabuchi Kiichiro!"

Solemnly, Otaki Goro said this name.

In this regard, Xiao Ai, who originally listened to Otaki Goro's story and had little reaction to the incident, was suddenly startled after hearing the name...
