Lana adds, 'I think it escalated to a point where she was either struck or pushed. I don’t believe that it was planned. I don’t believe in any of those bizarre stories, but I do know she would not have ended up somewhere where she would completely never, ever go in a million years or certainly not go out not dressed.
'There’s just too much that doesn’t add up to who Natalie is.
Wagner and Natalie wed in 1957 and divorced in 1962. The two reconciled and remarried in 1972. They were together until her death in 1981.
The couple welcomed a daughter, Courtney Wagner, in 1974. Natalie also had an older daughter Natasha Gregson Wagner from her marriage to British producer Richard Gregson from 1969 to 1971.
Earlier this year, Wagner was named a person of interest in the case after it was reopened in 2011.
Los Angeles County Sheriff’s Department Lieutenant John Corina said in an interview with CBS' 48 Hours, 'As we’ve investigated the case over the last six years, I think he’s more of a person of interest now.
'I mean, we now know that he was the last person to be with Natalie before she disappeared.'
Wagner has refused to speak with investigators since they began to look into the circumstances surrounding Wood’s death again.
Corina said of Wagner, 'I haven’t seen him tell the details that match all the other witnesses in this case,' adding, 'I think he’s constantly changed his story a little bit. And his version of events just don’t add up.'
In Wagner’s 2008 memoir, Pieces of My Heart, he wrote that after a night of drinking, he got into an argument with Walken over Wood’s career.
The now 87-year-old actor wrote, 'I picked up a wine bottle, slammed it on the table and broke it into pieces.'
When reflecting on how Wood fell off the boat, Wagner wrote it was 'all conjecture' and that 'nobody knows.'
He wrote: 'There are only two possibilities: either she was trying to get away from the argument, or she was trying to tie the dinghy. But the bottom line is that nobody knows exactly what happened.'
