The deadly siege that led to the murders of Queensland Constables Rachel McCrow and Matthew Arnold and Wieambilla local Alan Dare in December last year has been deemed a “religiously-motivated terrorist attack” by investigators. Queensland Police Deputy Commissioner Tracy Linford yesterday said attackers Nathaniel, Gareth and Stacey Train had developed Christian extremist and anti-government beliefs, including that there would be an “end of days” before Christ brought peace to Earth. She said there didn’t appear to be a defining “catalyst event”, but the pandemic and other global events were factors. The Trains are believed to have acted alone, but Linford said a similar ideology was behind the 1993 Waco massacre in the US, and police are working with the FBI to better understand their actions. The coroner will make the final determinations on the motivation for the attack.
