McKay

The family of Muriel McKay – who was held hostage and murdered 56 years ago – have offered a £1m reward for information that leads to the discovery of her remains.

Mrs McKay's grandson, Mark Dyer, told the BBC the family was inspired by the Mel Gibson movie Ransom to make a last-ditch attempt to solve the mystery.

Mrs McKay's body has not been found since she was kidnapped in 1969, taken to a farm in Hertfordshire and killed.

The reward mirrors the original ransom demand of £1m to return Mrs McKay to her family.

Her husband, Alick McKay – Murdoch's deputy - returned home to find her missing.
