Police have made a major breakthough in the case of a woman who was stabbed to death 32 years ago. Four people have now been arrested in connection with the death of 64-year-old Doreen Morris, who was found dead in her burned-out bungalow on the outskirts of Holyhead in March 1994.

Mrs Morris was stabbed to death with a fork after disturbing a burglary at her Anglesey home, Penrhyn Uchaf, a 2023 inquest found. North Wales Police said forensic developments and a detailed review of witness evidence had led to the arrests of a man and three women from North Wales on Wednesday morning (September 2). All four were arrested on suspicion of perverting the course of justice as part of an ongoing review of the case. Mrs Morris’ family have been informed of the latest development. Joseph Carl Westbury was found not guilty of murdering Mrs Morris in 1995. He also denied breaking into her property on Mill Lane. Mr Westbury took his own life in May 2016.

The North Wales Police Major Crime Review Team began a fresh review of the case in 2024, three decades after Mrs Morris’ death.

Police said the team’s work, including new forensic results and a detailed examination of witness evidence, had provided grounds for officers to interview the four people arrested.

Mark Pierce, Senior Review Officer, 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 as part of the ongoing review of the case.

“Throughout the review our thoughts have been with Mrs. Morris’ family, and I hope that this case shows that it doesn’t matter how much time has passed we will always seek out new opportunities to get justice for victims and their families.”

North Wales Police is continuing to appeal for information about the case.

Anyone with information has been asked to contact police on 101 or Crimestoppers, quoting Operation Epose, North Wales Police.
