ITV has expanded its content library with the addition of a gripping true crime documentary series titled 'When Death Comes Knocking.' Originally aired on the True Crime channel in 2025, this series examines several murder and crime cases where critical evidence was obtained from home security cameras. This unique angle provides viewers with a chilling look at how technology can play a significant role in solving violent crimes.

The latest episode, 'Dressed To Kill,' delves into the tragic murder of Nicki Collingbourne in Hertfordshire, which has captivated the audience with its suspenseful storytelling and the visual elements of real surveillance footage. The episode presents the investigation surrounding Nicki's murder, primarily focusing on the prime suspect, a man conspicuously dressed in a high-visibility jacket. The combination of real-life events and engaging dramatization has made this series particularly popular among true crime enthusiasts.

Available for streaming on ITVX, all ten episodes of 'When Death Comes Knocking' can now be accessed for free, highlighting ITV's initiative to provide compelling content that resonates with a growing audience interested in the true crime genre. By showcasing real criminal investigations and the often-harrowing evidence that can surface, this series not only entertains but also raises important questions about safety, surveillance, and the often-grim realities of crime in both the UK and the US.
