Robert Durst married Kathleen McCormack in 1973 when he was 27 and she only 19. Nine years later, Kathie, as she was known by those close to her, disappeared. Durst told police he last saw his wife when he dropped her off at a Westchester County train station. Friends say she complained of problems in her marriage. Durst has never been charged in connection with her disappearance, and the 1982 case remains unsolved.
