The family of a woman who was murdered 53 years ago have called for police to carry out a fresh search of the farm where they believe she is buried.
Muriel McKay, 55, died following a bungled kidnap plot by two brothers who mistook her for the wife of Rupert Murdoch.
Nizamodeen and Arthur Hosein, then 22 and 34, were jailed for life for Muriel’s 1969 murder but her body has never been found.
Nizamodeen, 75, allegedly told her family’s lawyer last year that he buried her on the Hertfordshire farm where they held her captive but a search of the area in April found nothing.
Now Muriel’s daughter, Dianne, 82, has written to Met Commissioner Sir Mark Rowley claiming his officers were looking in the wrong place.
She wrote: “Grudgingly, the land owner permitted a controlled search of a restricted area, dictated by his terms with many rules and regulations.
“As we were desperate, we agreed to them. We just wanted to locate my mother’s remains since she disappeared 53 years ago.
“During my visit, I met with the team who showed me the isolated areas they had searched. I was surprised to note that there was no ground-penetrating radar scanner present. When I asked about this, I was advised that a scanner had only been used for one day.”
She added: “We now know that the Met had only used and relied on Getty images of the farm which the family had provided them with. They did not use any of the original information or data from the search in 1970.”
She also accused a police officer of shouting at her after the site visit.
She wrote: “I was speechless. I could not believe what was going on. The [officer] was accusing me of things that were untrue just minutes after I had just lost all hope of finally finding my mother’s remains.”
A letter written by her son to the landowner said: “I have had numerous conversations with Nizamodeen, who insists that my grandmother is in that specific location in which the police never checked.
"Before we obtain the search warrant, I wanted to see whether you would consider allowing for an accurate and non-invasive scan in the original area of interest. With your help, we can instruct a third-party company ... to carry out this scan.”
The brothers had followed Murdoch’s chauffeur-driven Rolls- Royce in December 1969, unaware he had lent it to Alick McKay, his UK deputy.
They demanded a £1million ransom after taking Muriel from her home in Wimbledon, South West London.
It had been suspected that she was fed to pigs on the 11-acre farm in Stocking Pelham, Herts, owned by Trinidad-born Arthur.
Hosein is said to have now told her family that she collapsed and died while watching the news.
The brothers were given life at the Old Bailey for her kidnap and murder.
The conviction in 1970 is thought to be the first obtained without a body.
Documentary-makers last year tracked Hosein to Trinidad, where he was deported after spending 20 years in jail. Arthur died in prison in 2009.
Hosein is said to have told a barrister hired by the McKay family he wanted “closure” before he died and “met his maker”.
