The estranged mother of conservative talk-radio host Dr. Laura Schlessinger was found murdered Dec. 16 in her Beverly Hills condo. According to police, Yolanda Schlessinger, 77, had been dead for weeks. "I am horrified by the tragic circumstances of my mother's death," Schlessinger said Friday in a statement, "and so sad to learn that she died as she chose to live — alone and isolated."
