Episode 121: The Locked Bathroom Murder Case (Part 1)
Scenario: Two sisters, Mindy and Maya, are packing boxes and drinking glasses of beer, one of which, has sleeping pills dissolved in it. The next day, Conan, Richard, and Rachel are on their way to a Yóko concert when Richard discovers he lost his ticket. He overhears Mindy on the payphone and her situation about a friend who is unable to go to the concert because of a cold. Richard asks her for the spare ticket and she accepts as long as he drives her to her house to pick up her sister Maya. Upon arriving, they find that Maya has taped herself inside the bathroom. Richard, Rachel, and Mindy bust the door down to discover Maya dead from a slit wrist. Only her fingerprints were on the tape and two mixed cleaners were found near the body. Mindy, the prime suspect, is seen hysterically laughing over her sister's death while alone in a room. Everyone is convinced that Maya committed suicide, however, Conan believes that a vicious murder took place, and Mindy Garrett was the cold-blooded killer.
While on the way to a Yoko Okino concert Kogoro loses his ticket. Luck seems to be on his side when a young lady named Masayo Aoshima has an extra ticket, but the concert ends up being the last thing on their minds when they walk into her sister Mina's house and comes upon an apparent suicide. Conan has his own suspicions though, since he has caught Masayo laughing hard, but can he find enough evidence to prove contrary when the victim is found in a sealed room?
