Season 15

Episode 36: The Shadow of the Black Organization (The Young Witness)

A rockstar named Roku Itakagi has been missing for the past few days. A young boy named Takumi Hashiratani claims that on New Year's Day, he witnessed a man carrying Itakagi in a bag and throwing him over a bridge. Takumi claims that the man had a dark car, a nail on arm, and that he saw a giant glowing hammer in the background. Kogoro is skeptical at first but realizes Takumi is telling the truth when the news confirms that the body of Itakagi was found in a bag floating in a river. From Takumi's testimony, Kogoro, Ran, Conan, and Eisuke search for the bridge where the body was thrown over.
