**I'm the Killer! Three Independent Murderers? Reveal the Mystery of the Disguised Murder!** (私が殺しました! 3人の単独犯? 偽装殺人の謎を暴け! ,*Watashi ga Koroshimashita! Sannin no Tandokuhan? Gisō Satsujin no Nazo o Abake!*[?](/wiki/Help:Japanese "Help:Japanese")) is the 12th episode of the [Challenge Letter to Shinichi Kudo](/wiki/Challenge_Letter_to_Shinichi_Kudo "Challenge Letter to Shinichi Kudo") live-action drama series. It was first aired in September 22, 2011.
Machiko Sonoda, [Ran Mouri](/wiki/Ran_Mouri "Ran Mouri")'s computer school teacher and [Kogoro Mouri](/wiki/Kogoro_Mouri "Kogoro Mouri")'s drinking buddy, is found lying still – presumably dead – behind the closed shutter of Beika City Bank's safe-deposit box floor. There is a warning – the moment the shutter is open or the police make a move, the bank will be exploded. When asked for the murder culprit, all three suspects – Yuzo Nimura, Yoko Sakai and Ryosuke Hasegawa – raise their hands. Can [Shinichi Kudo](/wiki/Shinichi_Kudo "Shinichi Kudo") find the true culprit and prevent the 'explosion'?
