Murder detectives are investigating the site in Hertfordshire, where one of Muriel McKay’s abductors confessed to burying her body. Officers have been visiting the farm near Royston since February and work has now begun in an effort to find answers. Chief Inspector Detective Mark Cranwell said: “We are very grateful to the landowners for allowing us to carry out this work and we are keeping the Muriel family fully informed. “While two men have been previously convicted of murder, the family has lived for more than 50 years without knowing where Muriel’s remains are. “At this stage we do not know how long the excavation will take or what we will find, but it would be a huge relief and a sense of closure for everyone if Muriel’s remains were discovered.” Read more: Muriel McKay – the woman who disappeared Picture: Muriel McKay with her husband Alick The police will initially focus on clearing various areas and then will use ground penetration radar to detect any irregularities under the ground. Mrs. McKay was abducted from her London home in 1969 by brothers Arthur and Nizamondin Hussein. They had confused her with Rupert Murdoch’s wife and demanded a ransom of 1 1 million for her return. After a bad police operation, the brothers were arrested and convicted of Muriel’s murder, but her body was never found and her captors did not reveal what had happened to her. However, new hopes emerged last year when surviving brother Nizamodeen finally told the family’s lawyer that Muriel had died of a heart attack and had buried her near the farmhouse.
