Oscar-winning actress Patty Duke, who hit the trifecta of stardom with her turns on TV, in the movies, and on Broadway, is dead. Duke, who was 69, died due to sepsis from a ruptured intestine, her managers said. "I love you Mom," one of her actor sons, Sean Astin, said in a statement confirming his mother's death. The Queens-born daughter of a troubled cashier and alcoholic cab driver, Duke overcame a dark childhood to become one of the Hollywood's most respected actresses and president of the Screen Actors Guild from 1985 to 1988.
