Max McIntyre, who died last week age 89, claimed to know what happened to the siblings who went missing at Glenelg beach in 1966.
“I know a lot about the Beaumont killings,” McIntyre says in the video which was taken two years ago.
“At the moment I’m researching the death of the Beaumont’s because the only person that’s going to clear my name is me,” he said.
However, McIntyre's son Andrew believes his father is lying and that he did play a part in their disappearance.
“My father was involved in the abduction and murder of the Beaumont children,” Andrew says in the interview with 7 News.
Andrew believes his father and friend Anthony Munro (who abused Andrew when he was a child) were both involved and is certain that Jane, Arnna and Grant Beaumont are buried in a filled sink hole on his father's property.
“Both my father and Anthony Munro were involved with other people," Andrew claims.
