CBS 48 Hours says a sheriff’s officer has called actor Robert Wagner, 87, a “person of interest” in the “suspicious” 1981 drowning death of his then-wife, actress Natalie Wood. It is very unclear just what this might mean coming so long after the death and many investigations into what happened. Wood was a star from childhood. She appeared in “West Side Story,” “Miracle on 34th Street” and “Rebel Without a Cause.” She was traveling on her family’s yacht, Splendour, with Wagner, the ship’s captain Dennis Davern and her friend, actor Christopher Walken. Wagner and Wood are said to have argued and Wood took off in a dinghy. The authorities say they have re-investigated the case over the last six years and now think of Wagner’s as a person of interest.
