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.

The first witness was 12 year-old Lolorrbra (known as Lala) who testified in detail that he saw Arkirkra, Padygar and Marungali kill Brooks. He also testified that all the Aboriginal people that had helped them were now dead. Constable Murray took the stand next, his evidence becoming so involved in justifying his own actions in killing suspects that Justice Mallen reminded him that he himself was not on trial and to avoid facts not relevant to the guilt of the accused. The court then adjourned for lunch. The verdict was a foregone conclusion as all that remained was the reading of the confessions made by the accused in Alice Springs. Despite lunch for the jurors being provided by the local hotel, two of the jurors went home to eat. A furious Justice Mallen dismissed the jury, ordered a new jury be empanelled and a new trial to be convened the following day. The new trial began with Lolorrbra being asked to repeat his evidence. This time his evidence, although still maintaining that the accused were the murderers, was completely contradictory. Under cross examination it became apparent within minutes that he had been coached on what to say. When the prosecution tried to introduce the written confessions of the accused, Justice Mallen pointed out that as the accused had been charged by a South Australian rather than Central Australian magistrate he would disallow the statements. The prosecution declined to call the accused to testify. Murray took the stand next, angering Justice Mallen when he repeated his justifications for killing suspects. The judge remarked "It appears impossible for all those bands of natives to be associated with the murder of Brooks. It looks as if they were shot down at different places just to teach them and other aborigines a lesson." With no evidence of guilt presented, Justice Mallen ordered the jury to acquit the accused.
