Overview
- 24 Hours in Police Custody: A Family Vendetta airs over two nights on Channel 4 at 9pm on December 8 and 9.
- Previously unseen custody-suite and interview footage shows Stephen Alderton largely refusing to answer detectives’ questions.
- Investigators describe evidence that a Beretta shotgun was fired multiple times and reloaded during the attacks.
- Police recount the timeline: Joshua Dunmore was shot at his Bluntisham home, then his father Gary was killed 31 minutes later in Sutton; armed officers arrested Alderton on the M5 the next morning.
- Alderton admitted two counts of murder and, after an appeal, is serving a life sentence with a minimum term of 30 years, with texts and post‑arrest remarks tied to a family court dispute.
