Meitantei Conan › Season 1

Chapter 3 — An Idol's Locked Room Murder Case

Three days later, Professor Agasa gives Conan the "voice-changing bow-tie" and tells him that Ran (Rachel) has been worried about Shinichi (Jimmy). After Conan's first day at school his classmates Ayumi Yoshida (Amy Yeager), Mitsuhiko Tsuburaya (Mitch Tennison), and Genta Kojima (George Kaminski) plan to follow Conan home to befriend him. Singer Yoko Okino goes to Kogoro's (Richard's) agency to ask him to investigate a suspected stalking. When they arrive at Yoko's apartment, they find a dead man stabbed in the back with a knife. The dead man was Yoko's high school boyfriend so Yoko becomes one of the three suspects. The other two suspects are Yamagishi Eiichi, Yoko's manager, and Ikezawa Yuko, one of Yoko's rivals. Conan investigates and determines how the crime was committed. After knocking Kogoro unconscious with an ashtray, Shinichi impersonates Kogoro's voice with the voice-changing bow-tie and tells everyone at the scene of crime that the man killed himself. The man made a block of ice with a knife inside it and laid on top of it until the knife was in his back. Later in the week, knowing that Ran has been stressed since Shinichi's disappearance, Conan gives Ran a call while using his bow-tie in order to sound like his normal self since his current voice is his voice when he was a child. He tells Ran that he is on a difficult case and will return when it is solved. (Source: Wikipedia)
