"48 Hours" investigates Casey Kasem's death: Family battle goes nuclear

Radio icon Casey Kasem died more than four years ago, leading to a bitter dispute over his final resting place and the estate, estimated to be between $80 and $100 million. His three adult children filed a wrongful death suit against his second wife, Jeannie Kasem. She later filed a countersuit. Both parties reported claims of cruelty and neglect. Peter Van Sant spoke to Kasem’s wife and his daughters for Saturday’s “48 Hours.”
