On 15 August, dingo trapper Bruce Chapman arrived at Coniston and William George 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.
