Muriel McKay’s son has joined police teams at the site of a new search for his mother’s remains.
Ian McKay, 82, flew from his home in Australia to visit the Hertfordshire farm where his mother’s killer says he buried her 55 years ago.
The recent confession from convicted murderer Nizamodeen Hosein – after years of silence – persuaded detectives to begin a new dig.
As he walked up the footpath to the farm Mr McKay said: “I never came to the farm and I always found it difficult to talk about my mother’s disappearance.
“But it was important to be here now to make sure the police are acting on the information provided by Nizam.”
Mr McKay was 27 when his mother was kidnapped from her London home and held for ransom at the farm just after Christmas in 1969.
Nizam and his brother Arthur had planned to kidnap the wife of media mogul Rupert Murdoch, who had just bought The Sun newspaper, but bungled the crime.
Muriel, who was 55, was the wife of Murdoch’s deputy Alick McKay.
Ian McKay and his nephew Mark Dyer, who has led the campaign for a new search, were met by detectives and led to the excavation site.
Mr McKay said: “I’m not sure how I feel. I really hope that my mother is here and we can take her away for a proper burial.”
The Metropolitan Police expect to spend five days at the site using specialist search teams, archaeologists and forensic analysts.
They searched a patch of land on the farm near the current excavation site two years ago, but found nothing.
