Peter McKean, alias William McDonald, bunked with William ‘Yorkie’ Marriott at a shepherd’s hut near Kojonup, both working for the same local farmer. Marriott was known for quietly saving his wages, and in June 1872 he vanished. His body was found slumped behind a cart more than a week later, the head so badly gnawed by dogs that he could only be identified by a missing finger on his right hand.
McKean was arrested on circumstantial evidence and convicted at the Albany Circuit Court of robbing and killing Marriott with an axe. After his arrest, McKean claimed Marriott had been killed by ‘a vicious horse’. He never offered proof, and the excuse died with him on the scaffold.
He was hanged at Albany on 12 October 1872, the rope worked by a fellow convict before a crowd that included schoolchildren.
