Karen discovers Burt’s corpse near her apartment in his condominium and his time of death is exactly 7:30PM. The police suspect Karen because she has a motive, but also an alibi. She was with Amy at her office watching the TV show Masked Yaiba at that time. While visiting her apartment, Conan realizes the illusion used and accuses Karen as the murderer.

To incriminate Karen, Amy placed the Masked Yaiba card from the office deck into the condo deck.

Karen turns herself in without resistance.
