S1·E875 The Mysterious Prophetic Buddha!

Kogoro, bringing along Ran and Conan, is requested to investigate a Buddha statue rumored to have moved on its own. He meets Eikyo Fukuhara, his family (wife Masako, daughter Yuka, and son Eizen) and Buddhist trainee Junko Wakuda. After dinner, Eikyo displays uncaring behavior, leaves to go pray, and is later found dead with a knife in his neck. Kogoro, after finding clues thanks to Conan, declares Junko to be the killer after he attempted to scare Eikyo. Junko confesses but Conan isn’t satisfied. After finding rice powder near the victim, Kogoro is tranquilized and Conan reveals Masako to be the real killer. She discovered Junko’s scare tactic had failed, stabbed her husband to death, and framed Junko for the murder. Masako confesses stating Eikyo‘s rude and cruel treatment to his family as her motive and has a sense of relief now that he is dead. She maniacally laughs over her actions as she is arrested.
