Season 5

George McPhee, sentenced to life imprisonment for murder and assault when in 1984 a woman, Elizabeth "Totsie" Sutherland, was strangled and then stabbed during the burglary of her cottage in the Scottish Highlands. McPhee was a getaway driver in a series of burglaries, but he had an alibi to show he was committing crimes many miles away at the time of the killing.
