Decades after Natalie Wood’s tragic death, the late actress’ sister Lana Wood is speaking out about the star’s November 1981 disappearance and her belief that Natalie’s husband Robert Wagner was involved in her passing. 

In a preview video exclusively obtained by In Touch of Lana’s upcoming appearance on the Dr. Phil show alongside Fatal Voyage: The Mysterious Death of Natalie Wood podcast host Dylan Howard, Lana can be seen alleging that Robert has “something to hide” regarding Natalie’s death. Watch the Dr. Phil preview clip below!

“Police now believe this was foul play,” podcast host Howard told Dr. Phil in the clip. Then the TV star asked Lana, 72, “Why do you think [Robert is] not talking to the police?” to which she replied, “He has something to hide.”

“Are you suggesting that he knocked her out and threw her in the water?” Dr. Phil later asked Lana, which prompted her to say, “Something like that, absolutely.”
