Robert Richens has had his minimum prison term increased for the murder of Rachael Vaughan following a hearing at the Court of Appeal.

Richens, 35, of Luther Street, Oxford, pleaded guilty to one count of murder at Oxford Crown Court on 12 December 2025.

He was originally sentenced on 6 February 2026 to life imprisonment with a minimum term of 16 years and one month.

Following a referral by the Attorney General, Ellie Reeves KC MP, the Court of Appeal found the sentence was unduly lenient and increased the minimum term to 19 years and six months on Thursday 23 July.

The Attorney General’s Office said Ms Vaughan was killed following a prolonged controlling and abusive relationship.

The court heard that Richens fatally assaulted Ms Vaughan at her home in Abingdon, where nearby residents reported hearing screams during the attack.

Ms Vaughan sustained multiple serious injuries as a result of what was described as a violent and prolonged assault.

After her death, Richens remained at the property for several hours, attempted to clean the scene, left, later returned and called police.

Thames Valley Police said the case followed the murder of Ms Vaughan, aged 40, at a property in Abingdon on 30 May 2025.

Attorney General welcomes increased sentence

The case was referred to the Court of Appeal under the Unduly Lenient Sentence scheme.

The scheme allows certain Crown Court sentences to be reviewed by the Attorney General’s Office if they are considered to be too low. If the Law Officers believe a sentence appears unduly lenient, they can ask the Court of Appeal to review it.

Ellie Reeves KC MP said Richens had murdered Ms Vaughan in the place where she “should have been safest”.

She added: “Domestic murder destroys lives and sentences must reflect the horror of such crimes.”

Police say sentence now reflects the offence

Thames Valley Police’s Major Crime Unit led the investigation.

Senior investigating officer Detective Chief Inspector Stuart May said the investigation team welcomed the Court of Appeal’s decision.

He said the increased sentence “recognises the full nature and circumstances of this offence”.

DCI May added: “Richens’ actions were heartless. He left Rachael alone in her house, made no attempt to help her or seek medical attention and he only contacted police when he had nowhere else to turn.”

He said the force’s thoughts remained with Ms Vaughan’s family and friends.

What the sentence means

Richens remains subject to a life sentence.

The minimum term is the period he must serve in prison before he can be considered for release by the Parole Board. It does not mean he will automatically be released at that point.

If he is ever released, he will remain on licence for the rest of his life and could be recalled to prison if he breaches licence conditions.
