For more than 40 years, Pam and her daughter Jodie have carried their own theory about what happened to Des Carr that he never simply wandered away, and that his disappearance may have involved foul play.

They share memories of Des, the days after he vanished, and why they believe the answer could still lie somewhere along the remote roads of the Kimberley.

Then, just as Jodie hopes someone might hear the podcast and finally break their silence, a message arrives.

A man named Robert says he knew Des and claims he saw him again after he disappeared.
