New Natalie Wood Murder Charges

The National ENQUIRER caught Robert Wagner out with his son Michael in L.A. — just weeks after a former employee said the star “deserves to be arrested” for the death of Natalie Wood! Dennis Davern, skipper on the yacht where Natalie spent her mysterious final night, has written an open letter to police saying: “I know what [he] did to Natalie!"

The damning statements in the April 12 letter, obtained by The ENQUIRER, include this chilling passage: “I know what RJ [Wagner’s nickname] did to Natalie. There’s plenty of evidence, but the higher-ups are stalling in seeking justice for a woman who deserves it.”

Dennis told The ENQUIRER that he decided to speak out after Natalie’s eldest daughter, 45-year-old Natasha Gregson Wagner, implied that people who think Wagner murdered the actress are “conspiracy theorists.” Dennis was one of only four people aboard the Splendour [pictured] on the night of Nov. 29, 1981, and wants Natasha to realize her beloved 86-year-old stepfather isn’t as innocent as he claims.

“I always wonder if [Natalie’s] girls know I passed the polygraph — that I’m not just saying these things,” Dennis told The ENQUIRER. He's seen here on the Splendour with three investigators from the Los Angeles County Sheriff's Department Homicide Bureau. The ENQUIRER had the bombshell exclusive on how police had flown the former skipper to Hawaii last year so he could walk them through Wood's final minutes.

Natasha — whose father is film producer Richard Gregson — discussed her mother’s death while recently promoting a new fragrance called "Natalie." The showbiz scion said that the facts behind Natalie’s fatal plunge “don’t concern me,” and blasted allegations against Wagner as “preposterous.”

Many close to the late actress are furious that Natasha is cashing in on her dead mother’s name while defending the actor — who police still call “a person of interest” in the case. “It’s disgusting that Natasha evokes her mom’s memory, but protects Robert Wagner despite all the evidence against him,” an insider told The ENQUIRER.

But The ENQUIRER was there with exclusive video when Natalie's heartbroken sister Lana Wood confronted Wagner at a hotel in Palm Springs, Calif.! The former “Hart to Hart” star didn’t know he was being secretly taped when Lana hit him with the bombshell challenge: “Why won’t you speak to the detectives?”

Dennis has directly implicated Wagner in Natalie’s death, saying the actor flew into a violent rage aboard the Splendour as he accused Natalie of having an affair with her “Brainstorm” co-star, Christopher Walken — who was also on board that night. “The last expression I saw on her face was pure humiliation as she stormed off to her stateroom,” Dennis revealed to The ENQUIRER.

Natalie's death was ruled an “accidental drowning,” but the case was reopened in 2011. The cause of death was changed to “drowning and other undetermined factors” due to bruises on her body. In his letter to authorities, Dennis wrote that when Natalie’s lifeless body was discovered in the water: “I saw the bruises" — but the skipper claims that Wagner convinced him to stay quiet.

“That was the worst mistake I ever made," Dennis told The ENQUIRER. "The detectives never questioned my credibility. It’s only been questioned by the fans that the Wagner family continue to dupe!”
