Ep. 147: Conan uncovers Keizo's elaborate murder scheme involving a fishing line and a hidden knife.

147

Conan pieces together the evidence surrounding Keizo, the prime suspect in his wife Kayo's stabbing death. The officers reveal that Keizo rigged a fishing line to Kayo's exercise bike and a knife concealed in a bookshelf. When Kayo pedaled, the mechanism pulled the knife down, killing her instantly. Keizo then manipulated the investigation by directing officers away from the crime scene while he destroyed evidence. He pricked his finger to create a blood trail as proof of his presence. Keizo confessed that he orchestrated a robbery at his own bank to fund Kayo's lavish lifestyle. However, she was held hostage during the heist and identified one of the culprits, exposing Keizo as the mastermind. Two hours later, the robbers and Keizo were arrested.
