A new true crime documentary series, 'When Death Comes Knocking', is now available to stream for free on ITVX. The 10-part series explores murder cases where crucial evidence was captured on home security footage, including doorbell cameras and CCTV.
The series, originally released on the True Crime channel in 2025, covers both UK and American cases. One episode, 'Dressed To Kill', investigates the murder of Nicki Collingbourne in Hertfordshire, where the prime suspect was a man in a high-vis jacket.
Other cases include the murder of tech CEO Fahim Saleh, who was found dismembered in his Manhattan home, with lift footage revealing his killer, and the killing of a 16-year-old with a ninja sword, where CCTV uncovered a chilling tale of teenage revenge.
ITVX warns viewers of 'distressing scenes, real crime, graphic descriptions of murder'. The series has been praised by true crime fans on social media, with one calling it a 'must watch' and another describing episode three as 'crazy'.
