Natalie Wood's mysterious 1981 drowning now labeled "suspicious death"

On November 29, 1981, Natalie Wood drowned off Catalina Island near Los Angeles. She had been partying hard on a yacht with her husband Robert Wagner and Christopher Walken. The only other person on the boat was its captain. Wood's death was initially ruled an accident but in 2011, Los Angeles County police reopened the case. Now, stories from witnesses "portray a new sequence of events on the boat that night" according to police. From the Associated Press:

One of the witnesses described hearing yelling and crashing sounds coming from the couple's stateroom, she said. Shortly after that, separate witnesses heard a man and a woman arguing on the back of the boat and believe the voices were those of Ms. Wood and Mr. Wagner, (police spokesperson Nicole) Nishida said…

The statements differed from the original version of events provided by witnesses, including those who were on the boat, she said.

Wagner, who has always denied any knowledge of how his wife died, is now a "person of interest" in the case. Apparently he's refused to talk to investigators.
