Muriel Freda McKay, a 55-year-old Australian-born woman, was abducted from her home in Wimbledon, south-west London, on the evening of 29 December 1969. She was married to Alick McKay, a senior newspaper executive who was then a deputy to the media proprietor Rupert Murdoch. The abduction was the result of mistaken identity: the perpetrators had intended to kidnap Murdoch's wife, Anna, and were misled after following a Rolls-Royce that Murdoch had lent to Alick McKay, wrongly concluding that the McKay residence was the Murdoch family home.
When Alick McKay returned home that evening he found his wife gone and the house disturbed, and he reported her missing. Within hours a caller identifying himself as "M3" telephoned the family and demanded a ransom of one million pounds. Over the following weeks the caller made numerous further telephone calls and sent letters, and police mounted a lengthy operation built around attempts to deliver a ransom. Ransom drops were arranged in early February 1970, which failed. Evidence gathered during the operation led investigators to Rooks Farm at Stocking Pelham, Hertfordshire, which was owned by Arthur Hosein, a tailor. The farm was raided on 7 February 1970 and Arthur Hosein and his younger brother Nizamodeen Hosein were arrested.
Muriel McKay's body was never recovered. Despite an extensive search of the farm, no trace of her remains was found, and the case became one of the earliest murder convictions in the United Kingdom secured without a body. At trial at the Old Bailey the brothers were charged with murder, kidnapping and blackmail. On 6 October 1970 both men were convicted. The trial judge, Mr Justice Shaw, imposed life sentences, describing their conduct as cold-blooded and abominable, and added determinate terms for the kidnapping and blackmail offences.
Arthur Hosein remained in custody until his death in 2009. Nizamodeen Hosein served about twenty years before being released and deported to Trinidad. In later years Nizamodeen made statements indicating where Muriel McKay might be buried, prompting renewed interest in the case. Members of the McKay family travelled to Trinidad to speak with him, and the Metropolitan Police reviewed the new information. A fresh search of the farm, by then renamed Stocking Farm, was carried out in July 2024 but ended without her remains being found; police cited concerns about the reliability of the information provided. The family continued to press for further action, later offering a substantial reward, and in November 2025 a court formally declared Muriel McKay dead. The recovery of her remains has never been achieved, and efforts by her relatives to locate them have continued.
