20. Natalie Wood

Natalie Wood's lifeless body was found floating off the coast of the Catalina Islands almost a mile away from her yacht on November 29, 1981. Authorities concluded that the intoxicated former co-star of Rebel Without A Cause and West Side Story had slipped while attempting to access the yacht's dingy and that her heavy wool coat pulled her down to her watery demise. But reports of Wood arguing with her husband Robert Wagner, and flirting with their guest Christopher Walken, have clouded the investigation from the beginning. Wagner's people deny any foul play and both Wagner and Walken refuse to talk about the incident to this day. However, questions remain. Did Wood slip or was she pushed? Why would a woman who was frightened of water and could not swim want to hop on a dinghy?
