Wagner was onboard his yacht
Splendour with Natalie and actor Christopher Walken when
she vanished from the boat on the night of Nov. 29, 1981. Corina told The ENQUIRER that he believes Wagner is being uncooperative because “he probably feels like we’re looking at him as a suspect,” and said to CBS: "I think he's more of a person of interest now. I mean, we know now that he was the last person to be with Natalie before she disappeared."
