Natalie Wood's Sister: Robert Wagner Withheld Information
11/18/2011 6:05 AM PST BY TMZ STAFF
Lana Wood, Natalie Wood's sister, says she never believed Robert Wagner's version of the events that led to Natalie's death.
Lana tells TMZ ... she believes Robert wasn't honest with cops when they interviewed him about Natalie's death.
Lana also says she's not buying the story that Natalie was trying to secure a dinghy and fell overboard because she was deathly afraid of water -- to the point she wouldn't even go in her pool.
Lana says Sheriff's detectives have interviewed her about the case and they specifically wanted to know if the relationship between Natalie and Robert was "volatile."
And, Lana says, if someone was responsible for Natalie's death, they should be punished, despite the fact it's 30 years later.
