Robert Wagner jealous over Natalie Wood and Christopher Walken, 'credible' witness says

Was Natalie Wood's husband, Robert Wagner, jealous over her friendship with "Brainstorm" co-star Christopher Walken?

According to People, a couple of "very credible" new witnesses in the case of actress Natalie Wood's 1981 death indicate that an argument onboard the boat she disappeared from proves that he was indeed jealous. It's just one bit of new information that has led authorities to believe that her drowning might not have been an accident, as it was originally ruled nearly 40 years ago.

Wood, Wagner and Walken were all aboard Wagner's yacht Splendour on the night of November 28, 1981, and the two new witnesses reportedly corroborated Captain Dennis Davern's account from that evening, which differs from Wagner's. 

In Davern's account, which he gave when the case was reopened after authorities received "additional information" about Wood's alleged drowning back in 2011, he remembered feeling growing tensions between Wagner and Wood, who were married at the time. When Davern opened a bottle of wine, Wagner smashed it in front of Wood and Walken.

"And he yells at Walken, 'What are you trying to do, [expletive] my wife?'," People reports that Los Angeles County Sheriff's Lieutenant recounts Davern saying of Wagner on an upcoming "48 Hours" special.

The gravesite of actress Natalie Wood is seen in the Westwood Village Memorial Park in Los Angeles, on August 18, 2009. The burial spot located just above the final resting place of Marilyn Monroe is going on sale for a cool 500,000 dollars on auction website eBay. The tomb in the Westwood Village Memorial Park in Los Angeles is currently occupied by one Richard Poncher, who died 23 years ago aged 81. But his widow is having his body moved over one spot and auctioning the site above Monroe's, hoping to earn enough to pay off her 1.6-million-dollar Beverly Hills home. The cemetery is also the final resting place for celebrities as Natalie Wood, Truman Capote, Frank Zappa, Dean Martin, Jack Lemmon, Burt Lancaster, Billy Wilder, and more recently Farrah Fawcett.

LONDON, ENGLAND: Legendary US singer Frank Sinatra in a picture taken 08 December 1951 in London with his bride of a month US actress Ava Gardner forming a piano and vocal duet at Washington Hotel before 'Midnight Matinee' show at the London Coliseum. Frank Sinatra, born 12 December 1915, was a playboy who married four times, twice to famous actress, Ava Gardner and Mia Farrow. But he was deeply attracted to the actress; his biographer Kitty Kelley wrote that Gardner was the only woman he respected because he knew he could not dominate her. Sinatra got married for the last time in 1976 to Barbara Marx, widow of comedian Zeppo Marx of the four Marx brothers. Sinatra number his conquests, according to Kelley, among Hollywood's greatest beauties, including Marlene Dietrich, Judy Garland, Natalie Wood, Elizabeth Taylor and Victoria Principal.

Wagner's account of the argument alleges that Wood wasn't there for the wine smashing, which he says happened during a conversation about Wood's career. He says that his wife had already gone "belowdecks," and he had last seen her alive "fixing her hair at a little vanity in the bathroom."

And, despite Davern remembering the argument differently, that doesn't mean that he necessarily thinks Wagner was responsible for his wife's death.

"The only thing I know is what happened on the boat that night, I really can't say that I would think [Wagner] is responsible," Davern told People back in 2011.

Several witnesses also remember hearing a male and a female voice involved in an argument on the back of a boat that night, according to new information cited in the upcoming "48 Hours" special airing on Saturday.

Davern says that Wood disappeared after the argument, which was around 11 p.m. that night on the boat. 

"Get off my f-cking boat!" he remembers shouting at her at one point in the night.

Later on, Davern recalled a distraught Wagner telling him that "Natalie is missing," but said, "We're not going to do that," when Davern suggested radioing for help. "We will wait to and see if she returns," Davern recalled Wagner telling him.

Of course, she never returned and was found floating, lifeless in the water hours later the next morning.

Wagner, who was married to Wood on two separate occasions, is now 87 and refuses to comment on the case. Walken is similarly silent about it.
