Natalie Wood's death 36 years ago has been one of Hollywood’s biggest mysteries, but the Los Angeles Sheriff's department has restarted its investigation as new evidence came to light in recent years. It was ruled an accidental drowning soon after the actress’s body was found floating along a Catalina Island beach on November 29, 1981, but the death certificate was recently changed to “undetermined” base on the revelations in Marti Rulli’s book, Goodbye Natalie, Goodbye Splendour. Rulli, Natalie's sister Lana Wood and Cold Case Research Institute director Sheryl McCollum join Nancy Grace for an in depth look at the case in this Crime Stories episode.
