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.
Moyasta
On 13 March 1921 a Moyasta farmer and Sinn Féin magistrate named Tom Shannon was murdered in his home by unknown assailants. According to the Irish Times on 7 April 1921, which based its article on a report from British government, the killing was done by other Sinn Féin supporters. The government report claimed that Shannon, a magistrate in the Sinn Féin courts, was trying to distance himself from the courts and had refused to pay local Sinn Féin taxes.
In fact, it was clear that the assailants spoke with a strange accent, something the English Court Of Inquiry was not told by the Royal Irish Constabulary. Due to the lack of information, the Court could only conclude that the murder was committed by "persons unknown". This gave the government the opportunity to use the event for some anti-Irish propaganda.
According to more recent research, the murder of Tom Shannon was part of a "secret murder campaign". This campaign was directed at prominent people, often elected representatives and magistrates. As a magistrate, Shannon fell victim of this campaign.
