An American serviceman and his British wife are among three suspects arrested for double shooting in Cambridgeshire

A recent US serviceman was one of three people arrested in connection with the murder of a father and son at separate addresses in rural Cambridgeshire.

The three had been arrested in an operation by armed police after the discovery on Wednesday night of the bodies of Gary Dunmore, 57, and his son Joshua, 32, at their homes six miles apart.

The serviceman, 27, originally from Ohio, is said to have been a member of the US Air Force stationed in the UK.

The police continued the questioning of the three Friday.

Joshua Dunmore’s body was found just after 9pm on Wednesday at an address in the quiet village of Bluntisham, while his father was found dead at a home in Sutton around 9:37pm.

It is clear that Joshua Dunmore was involved in a custody dispute with his former partner, which was only very recently resolved in his favor.

Police described the attack on the pair as “targeted”.

A 27-year-old man and his 33-year-old girlfriend were arrested at a hotel outside Cambridge shortly after the death, according to Cambridgeshire Constabulary.

A 66-year-old man was arrested behind the wheel of a vehicle, which was stopped by West Mercia Police as it was driving along the motorway in Worcestershire. Officers used a stinger to stop a white Peugeot 208.

Officers found a shotgun and the driver was then transported to Cambridgeshire for questioning.

All three individuals were initially held on suspicion of conspiracy to commit murder.
