Cambridgeshire shootings: Man killed a father and son

Gary and Josh Dunmore died of gunshot wounds at two separate properties in Cambridgeshire in March

A man who shot a father and son dead had a "shortlist of people" he intended to murder, a court has heard.

Gary Dunmore, 57, and Josh Dunmore, 32, died at separate properties in two Cambridgeshire villages in March.

When arrested hours later, Stephen Alderton told police "sometimes you have to do what you have to do even if it's wrong in the eyes of the law".

The sentencing of the 67-year-old - who admitted to the murders - has been adjourned until Monday.

Cambridge Crown Court was told the killings came two days after a family court hearing.

Josh Dunmore, the former partner of Alderton's daughter, was found dead at his home in Bluntisham, while six miles away his father was found dead at his home in Sutton on 29 March.

The court heard Alderton, of no fixed address, had written in a telephone message last year: "I've a shortlist of people I intend to murder."

Prosecutor Peter Gair said Alderton had a shotgun licence and lawfully held a Beretta shotgun which was used in both killings.

Alderton's wife died in 2020 and at the time he was living in a motorhome on a site in Willingham, the court was told.

Police said Josh Dunmore was shot at 21:09 BST and Gary Dunmore was shot 31 minutes later.

The prosecutor said it was likely Alderton knocked on Josh Dunmore's door and shot him "twice at close range" when he opened it, in the left chest and the right side of his head, which would have been "rapidly fatal".

Soon after the first shooting was reported in Bluntisham, the body of Gary Dunmore, 57, was found in The Row, Sutton

Gary Dunmore was also shot at close range, with three of four shots hitting him, the prosecutor said.

"The defendant had to reload as two shots can be fired from the shotgun," he said.

Mr Gair said Alderton was "rapidly identified" as a suspect.

His motorhome was picked out on automatic number plate recognition cameras and he was stopped by armed officers on the M5 near Worcester at about 01:30 that same night.

'Calm manner'

Alderton was the only occupant and "he volunteered that the shotgun was in the motorhome which it was", Mr Gair said.

Some family members who packed into the courtroom wept as details of the case were read, while more listened remotely from another room within the building.

Earlier, judge Mark Bishop asked for the case to be dealt with in a "calm manner" and stated: "I don't want any hard staring of the defendant by the family members."

In a victim impact statement, Gary Dunmore's mother Jane Phillips said: "Both were killed in the most vicious, cowardly way with no opportunity for self-defence."

Mitigating for Alderton, Adrian Langdale KC, said the defendant wrote in a letter to the court: "If I could turn back time I would.

"I regret there are not enough words of remorse I can offer to the families affected by this crime."

In the letter, Alderton wrote he was "not the person that this conflict and the family courts have driven me to become".

He added: "I've never been a violent person, I do not have a criminal record. I've been a respectable, law-abiding citizen all my life.

"What happened to me on 29 March, I do not know."

Mr Langdale said Alderton was "realistic enough to know... he will never be released from prison".
