Oscar Wallace, known also by the aliases James and Hasker, had only been free for six weeks when he committed a brutal armed assault on Mary Cook at her isolated farmhouse near Mount Beckworth, outside Clunes, on 4 August 1873. Her husband was away, and Wallace, disguised with a bran bag over his head and a sack about his body, entered the property, seized a double-barrelled gun, locked the children in an adjoining room, and attacked the homeowner at knifepoint. He then fled through the district, robbing several men, firing at a Mr Prentice near Beaufort, and reportedly heading toward a hotel to settle an old score. He had served two years in Pentridge for larceny and had openly threatened the life of a witness from that trial.
Senior Constable Woods disguised himself as a digger and tracked Wallace to a store near Beaufort, where he overpowered him before Wallace could use the butcher’s knife he still carried. Wallace was tried, convicted, and hanged at Ballarat on 11 August 1873. He reportedly showed complete indifference to his fate from the moment of his capture.
