"We haven't brought you justice... No-one's been called to account." This is the unflinching judgement of Gary Jubelin, one of the nation's leading murder investigators. He's reflecting upon the search for the killer of three Aboriginal children whose murders have haunted the small NSW town of Bowraville and left families torn apart. "Should the murders have been solved? Yes, they should have. Could the murders have been solved? Yes, they could have." Jubelin's verdict calls into question the actions of NSW police involved in the initial hunt for the killer. Reporter Debbie Whitmont takes several of the police officers involved back through the investigation to try and uncover why no-one has been convicted of the murder of 16-year-old Colleen Walker, 4-year-old Evelyn Greenup & 16-year-old Clinton Speedy in 1990 and 1991.
