Stay away from Conan.

Thus, seeing Kazato Kyosuke deny knowing about the police shooting in such a way, as if he couldn't remember the people he had treated, Takato couldn't help but smile slightly.

This slight change in expression was immediately noticed by Kyosuke Kazato, who was secretly observing Takato's reaction. He quickly deduced that Takato clearly already knew something and was deliberately saying this.

However, even so, Kyosuke Kazato couldn't show anything in this situation and could only wait and see what the detective would do.

At this point, Gao Yuan's expression turned to one of obvious confusion, and he asked:

"But... I've been concerned about these two incidents recently reported in the news, so I did some research specifically on the two victims, and among them..."

"Through some intelligence, I learned that the first Narazawa police officer who was killed seemed to be in a bad mood some time before the incident, so he had seen a psychologist."

"Psychologist?"

Upon hearing this, Officer Shiratori couldn't help but look at Kyosuke Kazato, clearly wondering if Takato had brought this up specifically because the psychologist was Kyosuke Kazato.
They clearly understood what Gao Yuan meant by those words, since he had been so direct.

Therefore, Kyosuke Kazato still said:

"Huh? Could it be that I'm the one who treated him? I'm really sorry, I've treated quite a few police officers, and often the psychological problems they seek are unrelated to their profession, so I may not know the profession of every patient who comes to me for treatment..."

"However... um, Officer Narasawa, right? If the name is correct, I can check the medical records later, maybe I can find it."

Kyosuke Kazato responded with the same words.

Obviously, this result was somewhat disappointing for Inspector Shiratori, Kogoro Mouri, and Conan. They had hoped to find some clues, but now the investigation was stuck in a quagmire, and they didn't know where to start.

Upon hearing this, Gao Yuan made no attempt to hide his feelings and directly stated:
"Is that so? I did find out that Officer Narasawa had visited your clinic, but since I don't remember... well, there's nothing I can do about it."

As he said this, it seemed that Gao Yuan would no longer pursue the matter further.

Just then, Kogoro Mouri saw Inspector Megure and Wataru Takagi walk past them. Seeing that talking to Inspector Shiratori wasn't yielding any useful information, and considering his closer relationship with Inspector Megure, Kogoro quickly made his choice and addressed the group present:
"Sorry, excuse me."

As he spoke, Kogoro Mouri quickly caught up with Inspector Megure and whispered in his ear:
"Inspector Megure, how's the investigation going regarding that matter?"

Upon seeing that it was Kogoro Mouri approaching, Inspector Megure immediately adopted a serious expression, waved his hand as if to distance himself from Kogoro, and responded simply and decisively:
"I'm very sorry, I don't want to talk about this."

After saying that, Inspector Megure left without looking back, not giving Kogoro Mouri a chance to ask any questions. On the contrary, Wataru Takagi was a few beats slower to react, so he remained where he was.

Seeing that Inspector Megure maintained this attitude, Kogoro Mouri couldn't help but become puzzled.

Why does he always refuse to talk to me?

So, seeing that Takagi Wataru was still there and hadn't left immediately, Kogoro Mouri couldn't help but glare at him, as if he were asking Takagi Wataru for confirmation.

Seeing Kogoro Mouri try to talk to Inspector Megure but be shunned by him, Conan, Takato, and the others came over. Takato casually remarked, "Mr. Mouri, haven't you realized yet? The police don't want outsiders involved in the investigation."

At the same time, Conan nodded in agreement:
"I think Inspector Megure must have some reason for not telling you."

After being so bluntly reminded by Takagi and Conan, Kogoro Mouri reacted with a flustered expression, grabbing Takagi Wataru and sternly questioning him:

"Is that so, Officer Takagi!"

"This... I don't think so..."

At this moment, Takagi Wataru couldn't help but feel a bit like he had been wronged, and replied with a helpless expression.

"Alright, Mr. Mori, you don't need to ask any more questions."

Seeing that things had come to this point, Officer Shiratori could no longer remain a bystander. He stepped forward and spoke to Kogoro Mouri with a serious expression, while his gaze swept over Takato, seemingly as a warning.

"And Mr. Akechi, too, conducted an in-depth investigation without the police's knowledge. Who knows, we might come after you at any time..."

This statement seems to imply that Gao Yuan's act of conducting an independent investigation might be overstepping boundaries.

"I need not know. You should understand now."

At this point, Officer Shiratori had said everything he could.

As soon as this somewhat strange English sentence was uttered, former detective Kogoro Mouri and the well-informed Conan naturally understood what it meant—

This is a code word used within the police force, emphasizing the isolation of non-essential personnel from information, which implies that the matter involves classified information.

Therefore, from this perspective, the fact that two criminal police officers were shot and killed in succession suggests that the matter may involve individuals within the police force, and these individuals may not even be ordinary people. It could be related to high-ranking police officers, meaning that this incident could potentially shake the entire police organization.

At this point, after Officer Shiratori said those words, both Kogoro Mouri and Conan fell silent. After all, since he had already said that, it was impossible to ask any further questions.

However, at this point, Gao Yuan's reaction was completely different from theirs. Instead, he seemed to have just learned about it and chuckled:

"Oh? So... that's how the police see it internally? What's the reason? Just because of that fact that the two shootings were committed by the same person? Or do they think...?"

"Because the second victim also had a police handbook in his hand?"

At this point, when Gao Yuan said these words, especially mentioning that the police handbook was in the hands of the other party when the second victim died—a piece of information that had not been publicly announced—everyone present, especially many police officers, stared at Gao Yuan with surprise and suspicion… (End of this chapter)
