2:01

Investigative journalist Mark Williams-Thomas interviews the step-grandfather of Tia Sharp, Stuart Hazell, who claims to have no idea what has happened to Tia. Her body was found the next day and police immediately moved to arrest Stuart and Tia's grandmother. Britain’s Darkest Taboos tells the stories of some of the most shocking and disturbing crimes within families and relationships. Every family’s worst nightmares are relived and re-told in unflinching detail by those left behind – by the families and friends, and by others whose lives have been touched - like the police officers and reporters involved in the cases.
