Did Robert Wagner pull an O.J.?
The County Sheriff's office in Los Angeles is now calling the 87-year-old actor a "person of interest" in the 1981 drowning death of his wife, Natalie Wood.
"As we've investigated the case over the last six years, I think he's more of a person of interest now," Lt. John Corina tells CBS News' "48 Hours" in an episode airing Saturday at 10 p.m. ET/PT. "I mean, we know now that he was the last person to be with Natalie before she disappeared."
"Do you believe Natalie Wood was murdered?" asks correspondent Erin Moriarity.
"I think it's suspicious enough to make us think that something happened," Corina says.
Details have been as murky as the water off California's Catalina Island on November 29, 1981, the night Wood disappeared from her family's yacht, Splendour.
But here's what is known:
Wood was 43 when she boarded the yacht with Wagner, her "Brainstorm" co-star Christopher Walken and the boat's captain. She was notoriously fearful of dark water.
Her death was initially ruled an accident, but the investigation was reopened in 2011 by the Los Angeles County Sheriff's Department. A year later, the coroner's office reclassified the cause of death as "drowning and other undetermined factors." The autopsy report notes there were a number of fresh bruises on Wood's body.
Wagner's account of the night's events has shifted over the years, and he has refused to speak with investigators since the case was reopened. Walken has reportedly cooperated.
"I think he's constantly changed his story a little bit," says Corina. "And his version of events just doesn't add up."
