Was legendary DJ Casey Kasem murdered? His daughter Kerri, who is embroiled in a long-running feud with his widow, Jean, spoke out to “48 Hours” on CBS, claiming her stepmother killed her father. “What she did led to his death,” Kerri says in the upcoming episode. Jean claims just the opposite is true. “They killed my husband,” Jean told Inside Edition last year. The children have filed a wrongful death lawsuit against their stepmother, while Jean has counter-sued for the same reasons.
