Coniston massacre
On 24 August, Murray captured an Aboriginal person named Arkirkra and returned to Coniston, where he collected Padygar (Woolingar had died that night still chained to the tree) and then marched the two to Alice Springs. Arriving on 1 September, Arkirkra and Padygar were charged with the murder of Brooks while Murray was hailed as a hero. On 3 September, Murray set off for Pine Hill station to investigate complaints of cattle spearing. Nothing has been recorded about this patrol, but he returned on 13 September with two prisoners. On 16 September, Henry Tilmouth of Napperby station shot and killed an Aboriginal he was chasing away from the homestead; this incident was included in the later enquiry. On the 19th, Murray again departed, this time under orders to investigate a non-fatal attack on the person of a settler, William "Nuggett" Morton, at Broadmeadows Station, by what Morton described as a group of 15 Myall Warlpiri people who were also in the same area.
Sir Henry Wilson, 1st Baronet
However, this claim has been challenged. Any order to assassinate Wilson would have had to have been relayed to them by Rory O'Connor (then in charge of British IRA operations) and the last assassination attempt contrived against Wilson had been set to be executed in 1921, not 1922. Coogan has suggested that Reginald Dunne, who had the confidence of both Michael Collins and Rory O'Connor, undertook the shooting as a last-ditch effort to provoke the British Government into retaliating, thereby uniting both sides of the Nationalists. Hart believes the assassins "acted alone in the (grossly mistaken) belief that Wilson was responsible for Catholic deaths in Belfast". The killers had only decided to attack the previous evening, and even on the day Sullivan had been at work until 1pm; the killers had no getaway plan.
