Stephen Alderton was jailed for life following the shootings of two people in Cambridgeshire in 2023
A TV documentary that follows the work of a police force will show the investigation into the murder of a father and son who were shot at their homes.
Stephen Alderton, 67, was jailed for life in October 2023 after admitting killing Gary Dunmore, 57, and Josh Dunmore, 32, in two Cambridgeshire villages.
The case will feature on 24 Hours in Police Custody on Monday and Tuesday, under the title “A Family Vendetta” on Channel 4.
Det Ch Insp Katie Dounias, from Cambridgeshire Police, said: “This programme will show how a family conflict playing itself out through the courts turned into a double tragedy through Stephen Alderton’s rash and brutal actions.”

Gary Dunmore and his son Josh Dunmore were shot within 31 minutes of each other
Josh Dunmore, the former partner of Alderton’s daughter, was shot twice in the hallway of his home in Meridian Close, Bluntisham, on the evening of 29 March 2023.
Police said that 31 minutes later Alderton shot Gary Dunmore three times at his home in The Row, Sutton, near Ely.
During the court case in the June of the same year, the prosecution said that it was “clear that the events were triggered by an ongoing family court case”.
It was also heard that Alderton had a shotgun licence and lawfully held a Beretta shotgun which was used in both killings.

Police said Alderton was arrested on the M5 the following morning
The documentary will follow the case from the first emergency call to the shootings, and then the arrest of Alderton by firearms officers on the M5 near Worcester the following day.
Det Ch Insp Dounias said: “My thoughts remain with the family and friends of Gary and Josh, some of whom bravely shared their experience with 24 Hours and bring to life the devastating impact of the shootings.
“Alderton’s sentence was raised on appeal to a minimum of 30 years, but no sentence is sufficient to make amends for the irreparable damage he caused to so many lives.”
