Coniston massacre
On 15 August, dingo trapper Bruce Chapman arrived at Coniston and Murray sent Chapman, Paddy and Alex Wilson and three aboriginal trackers to the soak to find out what happened. The three buried Brooks on the bank of the soak. In the afternoon two Warlpiri, Padygar and Woolingar arrived at Coniston to trade dingo scalps. Believing them to be involved with the murder Paddy arrested them but Woolingar slipped his chains and attempted to escape. Murray fired at Woolingar and he fell with a bullet wound to the head. Stafford then kicked him in the chest breaking a rib. Woolingaar was then chained to a tree for the next 18 hours. The next morning the posse, with Padygar and Woolingar following on foot in chains, set out for the Lander River where they found a camp of 23 Warlpiri at Ngundaru. With the posse encircling the camp, Murray rode in and was surrounded by Aboriginal people yelling, Brisco started shooting with Saxby and Murray joining in. Three men and a woman, Bullfrog's wife Marungali, were killed on the encounter, with another woman dying from her wounds an hour later. A subsequent search of the camp turned up articles belonging to Brooks. Stafford was furious with Murray over the shooting and the next morning returned to Coniston alone.
Coniston massacre
During his testimony, Murray said that the group had "shot to kill": Justice Mallen: Constable Murray, was it really necessary to shoot to kill in every case? Could you not have occasionally shot to wound?
Murray: No your honour, what is the use of a wounded blackfellow hundreds of miles from civilization?
Justice Mallen: How many did you kill?
Murray: Seventeen your honour.
Justice Mallen: You mean you mowed them down wholesale!
—"The Northern Territory Times", 9 November 1928 In the courtroom to hear this and other evidence of massacre was Athol McGregor, a Central Australian missionary. He passed on his concern to church leaders, and eventually to William Morley, outspoken and influential advocate of the Association for the Protection of Native Races, who did the most to secure a judicial enquiry. The Federal government was also under considerable pressure to act. The British media had been reporting on Australia's treatment of Aboriginal people (Australia was in financial difficulties at the time and an economic mission from London was considering financial assistance), a federal election was due on 17 November and the League of Nations had publicly criticized the case.
