Karla Cardno's father Gary John Duffin
The name and image of Karla Cardno is etched into the memory of so many of us.
Her 13-year-old body found in a shallow grave, after she had been raped and murdered.
Now it is her father that is creating headlines. He has just been convicted of the rape of a young girl - not much younger than his own daughter back then.
In a rare move, his girlfriend was charged and found guilty of rape too.
But 60 Minutes has discovered there is much more to this story of abuse of underage girls.
