The film star drowned at age 43 in the waters off Southern California’s Catalina Island over the Thanksgiving weekend in 1981. She had been yachting with her husband, actor Robert Wagner, and then co-star, actor Christopher Walken at the time of her death.

Continuing, he says, “We have unearthed critical pieces of evidence that were overlooked at the time. And this all paints a very disturbing portrait about the police investigation.”

Initially ruled an accident by the Los Angeles County coroner, the investigation into Natalie Wood’s death was re-opened in 2011, and the cause of death changed from "accidental" to “undetermined.”

Robert Wagner has been named as a “person of interest” in the investigation. Wagner categorically denies any involvement in Wood’s death, and no charges have ever been brought against him.
