"It was him"
During the trial at the Old Bailey on 14th September 1970, the Hosein brothers blamed each other, but neither confessed. Arthur Hosein was sentenced to life imprisonment and 25 years for kidnapping, 14 years for blackmail and 10 years for sending threatening letters. Nissan Hosein received the same sentencing, except for 10 years less on the kidnap charge.
To this day, no one knows what happened to Muriel McKay, except her killers.
