1. Wood, an actress best known for her roles in "Miracle on 34th Street," "Rebel Without a Cause" and "West Side Story," drowned in 1981. Her death was initially ruled an accident, but detectives reopened the investigation into her drowning in 2011.

    "As we've investigated the case over the last six years, I think (Wagner is) more of a person of interest now," John Corina, a lieutenant with the Los Angeles County Sheriff's Department, told producers for "48 Hours," according to CBS News.
  2. Wood went overboard in November 1981, while on her family's yacht as it was docked near Catalina Island, California. Wagner -- who was Wood's husband at the time -- was on the yacht, along with actor and friend Christopher Walken and boat Capt. Dennis Davern.

    Weeks before her death, she told a reporter that she was afraid of dark water, according to Vanity Fair.

    Investigators initially called the death an accident, but reopened the investigation in 2011, after Davern told reporters that he lied to police during their initial investigation. In an interview that year with NBC News, Davern said he believed Wagner was responsible for Wood's death.

    "We didn't take any steps to see if we could locate her," Davern told NBC News. "I think it was a matter of, 'We're not going to look too hard, we're not going to turn on the searchlight, we're not going to notify anybody right now.'"

    "Natalie Wood: Death in Dark Water" will air at 10 p.m. EST Saturday on CBS.
