Police have begun a new search for the remains of Muriel McKay, who was murdered in a kidnap-for-ransom case more than 54 years ago.
Nizamodeen Hosein and his brother, Arthur, mistook McKay, 55, for Anna Murdoch, the then-wife of the newspaper magnate Rupert Murdoch, when they kidnapped her in 1969. The pair held McKay at a farm in Hertfordshire and demanded a £1m ransom.
