Natalie Wood death: Investigator calls new witnesses "very credible"

[This story previously aired on July 4, 2020.] Charles Osgood |CBS News report: Actress Natalie Wood is dead at 43 the apparent victim of a drowning accident of Santa Catalina Island in California. Lt. John Corina [to reporters in 2011]: It was already determined to be an accidental drowning, but the information we received made us want to take another look at the case. Natalie Wood: [From "Biography"]:  I've always been terrified, still am, of water, dark water, sea water. Lt. John Corina [to reporters in 2011]: We have received information, which we thought was substantial… Robert Wagner [audio book]: Doug pulled up and got out of his boat.  "Where is she?" I asked him.  Doug looked at me.  "She's dead, R.J..."  My knees went out; everything went away from me." Robert Wagner [audio book]: Walken and I got into an argument. …At one point, I picked up a wine bottle, slammed it on the table and broke it into pieces. Natalie was already below decks at that point. Robert Wagner [audio book]: Natalie was in the master cabin and heard the dinghy banging against the side. She got up to retie it. She slipped on the swim step on the stern … and was either stunned or knocked unconscious and rolled in the water. The loose dinghy floated away. My theory fits the few facts we have.

In 2018, "48 Hours" first reported that the Los Angeles County Sheriff's Department had talked for the first time about their investigation into the drowning death of iconic actress Natalie Wood 36 years ago, calling her husband, actor Robert Wagner, a person of interest.

"As we've investigated the case over the last six years, I think he's more of a person of interest now," Los Angeles County Sheriff's Department Lieutenant John Corina says of Wagner in an interview with "48 Hours" correspondent Erin Moriarty. "I mean, we know now that he was the last person to be with Natalie before she disappeared."
