Chilling footage of two of the shooters responsible for killing a pair of Queensland police constables has been labelled a "vile murder confession" that highlights the duo's extremist, conspiracy-laden views.
Killer couple Gareth and Stacey Train uploaded their message in a grainy video to a now-deleted YouTube account about 7.40pm on Monday, hours after three people had been shot dead.
The sound of a police helicopter can be heard in the background, while the couple appears to be crouched inside the rural Western Downs farmhouse where they and Gareth's brother Nathaniel Train staged their ambush.
