At 8.00am on Monday 18th June 2001, Danielle Jones left home dressed in her schoolgirl uniform-and promptly vanished. The 15-year old's body was never recovered, but Danielle's parents soon learned that her 'Uncle Stuart', a close family friend, had concealed a decades-long history of sexual violence against teenage girls. Despite the absence of a body, Stuart Campbell was jailed in 2002 for Danielle's abduction and murder, and sentenced to life in prison. But how did Stuart Campbell become a violent sexual predator? What set him on a path of lies, abduction, treachery and murder? And how do you come to terms with his actions if he's your own flesh and blood?
