Paedo Black died in jail last year - when cops were just weeks away from charging him with Genette's murder.
Now, recordings from a 1990 counselling session Black had with counsellor Ray Wyre reveals the sick depths of the murderer's depravity, and are set to be broadcast for the first time on CBS Reality series Voice Of A Serial Killer.
Despite not yet being charged with any murders at the time of the recording, Black was serving life for attempting to abduct a six-year-old in Scotland - and cops suspected he had killed Genette and many others.
