UK Metropolitan Police officers have travelled to Trinidad to speak to the convicted killer of Muriel McKay who was murdered in 1969, in a bid to find her body.

BBC News reports that her body is yet to be found but one of her killers recently admitted to burying her body behind a barn in Hertfordshire.

Ms McKay was mistaken for the wife of business magnate Rupert Murdoch and was abducted and held for ransom – brothers Arthur and Nizamodeen Hosein were convicted for her kidnapping and murder.

Arthur died in prison in 2009 while Nizamodeen now lives in Trinidad as he was deported after serving his sentence.

Mark Randolph Dyer, the grandson of Ms McKay, said the Met Police told him they had taken Hosein “into custody for interviews” over the past two days.

He said the sessions were described as “productive”.

Hosein has denied murdering Ms McKay, but told her family he was in the room when she died.
