Veteran TV news producer Leroy Sievers, who spent ten years with CBS News before becoming executive producer of ABC's Nightline, died Saturday in Maryland at age 53 after chronicling his seven-year battle with cancer on NPR and developing a blog for cancer sufferers called "My Cancer." In a statement, former Nightline anchor Ted Koppel said, "Cancer was not in Leroy's plans. But he turned his battle with cancer into the most dramatic, the most moving and the most important story of his life."
