Four people have been arrested on suspicion of perverting the course of justice in connection with the murder of Doreen Morris, who was killed at her home 32 years ago.

North Wales Police confirmed that a man and three women, all from north Wales, were taken into custody on Wednesday morning.

The arrests follow a cold-case review into the death of 64-year-old Mrs Morris, who was killed in 1994 after disturbing a burglary at her bungalow, Penrhyn Uchaf, on Anglesey.

A 2023 inquest heard that Mrs Morris was stabbed to death with a fork when intruders broke into the property.

A man named Joseph Carl Westbury denied breaking into the bungalow and was acquitted of her murder following a trial in 1995. Mr Westbury died by suicide in May 2016.

According to North Wales Police, the latest arrests were made possible by advances in forensic science alongside a fresh review of witness evidence. The force confirmed that Mrs Morris's family has been informed of the developments.

Mark Pierce, senior review officer for North Wales Police, said: "Forensic results, combined with a detailed review of witness evidence, have provided grounds to interview four people on suspicion of perverting the course of justice."

Mr Pierce also appealed for anyone with information about the case to contact the police.

The identities of the four people in custody have not been released, and police have not disclosed the specific details of the forensic evidence that prompted the arrests.

I will continue to follow the investigation and provide updates as further details are released by North Wales Police.
