A senior officer would have been alerted to a family of killers "fixated" on police if he had access to interstate reports ahead of a fatal ambush of uniformed colleagues, a coroner has been told.
Brothers Nathaniel, 46, and Gareth Train, 47, opened fire on four junior constables as they walked up the driveway of a remote property at Wieambilla, west of Brisbane, late in the afternoon of December 12, 2022.
