Detectives hope the latest round of renewed interest in the mysterious 1981 death of actress Natalie Wood will bring forward new witnesses, but this may otherwise be the end of the investigation, a Los Angeles County sheriff's official said Monday, Feb. 5, 2018. Wood was found floating in the ocean during a Thanksgiving weekend yachting trip to Catalina Island with her husband, actor Robert Wagner, actor Christopher Walken and the boat captain. Her death was initially classified as a drowning. (AP Photo, File)
