Four people have been arrested 32 years after a pensioner was stabbed to death with a fork before her body was burned in her own home. Farmer's widow Doreen Morris, 64, was found dead in her burned-out bungalow on the outskirts of Holyhead, Anglesey, in March 1994.A post-mortem revealed the mother-of-four had suffered horrific burns to her body after her death, with detectives believing a blaze was started in her home following a bungled burglary. Police found a silver eating fork on the floor beneath the body, while property from the bungalow had been removed. A bloodstained hi-fi tape deck and amplifier were later recovered in nearby gorse bushes.The case has remained unsolved for more than three decades, but forensic developments and a detailed review of witness evidence resulted in a new breakthrough for investigators. On Wednesday, the North Wales Police Major Crime Review Team revealed a man and three women, all from North Wales, had been arrested in connection with the case.Mrs Morris' family has been informed. Four people have been arrested 32 years after pensioner Doreen Morris, 64, was stabbed to death with a fork before her body was burned in her own home in 1994 The silver eating fork (pictured) was found on the floor beneath Mrs Morris' bodyMark 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.'Previously, suspect Stuart Queen, who attended Holyhead police station in May 1994, claimed that on the day of the killing Joseph Carl Westbury had visited his home and handed him a bracelet. It was found to have belonged to Mrs Morris.Mr Queen, who claimed he had thrown the bracelet away, was charged with handling stolen goods. Upon his release from police custody, he made a statement claiming Mr Westbury had confessed to the murder and to stabbing Mrs Morris with a kitchen fork. At that stage the police had not known a fork might have been involved as the murder weapon.In his statement, Mr Queen said Mr Westbury had set fire to bedding to cover his tracks.Mr Westbury, then aged 22, was subsequently charged with murder – but later cleared by a jury at Chester Crown Court in 1995. He also denied breaking into Mrs Morris' property on Mill Lane. Mr Westbury took his own life in May 2016. An inquest originally recorded Mrs Morris's death as 'not ascertained', but her daughter Audrey Fraser battled for it to be changed to unlawful killing. A man and three women, all from North Wales, have been arrested in connection with the caseAt a reopened inquest in 2023, North West Wales senior coroner Katie Sutherland said: 'I find that Carl Westbury and Stuart Queen went to the bungalow with the intent to burgle it having been told it was empty. 'Mr Queen went up on the roof whilst Mr Westbury broke in through the back door, smashing the glass.'Once inside the property Mr Westbury had a confrontation with Mrs Morris where he bit her ear, stabbed her in the neck with a fork. Together, they removed property and set the bungalow ablaze.'Mrs Sutherland remarked: 'I heard evidence that Mr Westbury had a propensity for using gratuitous and extreme violence.'His violence towards his wife had included dousing her with turpentine and threatening to set her alight. 'This propensity evidence mirrors that he bit Mrs Morris which is an unusual type of violence (according to a former detective inspector), stabbed her with a fork and used an accelerant to set her bungalow on fire.'I find that he would lose self-control and react extremely violently,' the coroner said.Mrs Sutherland added: 'The evidence is indicative of murder. I am satisfied that the appropriate conclusion of the inquest into the death of Doreen Morris is unlawful killing.'She recorded Mrs Morris had died from a stab wound to the neck.Anyone with any information is asked to contact police on 101 or via Crimestoppers, anonymously, quoting Operation Epose, North Wales Police, on 0800 555 111.
