Graziers from neighbor properties in remote north Queensland had agreed to meet up at the boundary line where gunfire left three dead and one having to flee with bullet wounds to the stomach.
Police were examining several crime scenes on Friday. The only surviving victim had managed to provide his account and the man he accused of the shooting was one of three locals in custody.
On Thursday morning, emergency services were called to Bogie, near Collinsville, where a man was found with a gunshot wound and reported an attack on his family.
The bodies of two men and a woman were later discovered while police scoured a vast exclusion zone, not knowing if the killer or killers were still active and armed.
Nine News reported that the victims were graziers Merv and Maree Schwartz, and Maree’s adult son, Graham Tighe.
Maree’s other son, Ross Tighe, was the survivor who fled the scene in a ute to get help.
Three people were in police custody, while two others had been assisting police with their inquiries.
Acting Police Superintendent Tom Armitt told Nine News that, acting on the information provided by the survivor, police believed they had the shooter in custody.
“We believe one of those people [in custody] is responsible for this matter,” he said, adding that no charges had been laid.
