The smiling parents, the respectable groom, the helpful official... all with evil inside. Britain's Most Evil Killers explores the crimes of Britain's most brutal killers.
In March 2011, four adults who lived in a cul-de-sac in the Welsh town of Kidwelly were convicted of multiple sex offences against children and young adults. The group led by Colin Batley was described by the media as a "Satanic sex cult", a "quasi-religious sex cult" and a "paedophile cult." Episode from crime-series "Nightmare in Suburbia".
25 years after he first reported on it, Sir Trevor re-visits the case of Beverley Allitt, one of Britain's most prolific serial killers.
