More details have come to light about the trio behind the Queensland police shooting.

Brothers Nathaniel and Gareth Train were accompanied by Gareth's wife Stacey Train, who was previously married to Nathaniel, in their mission to kill these police officers.

The trio were all involved in the Queensland education sector before they left their jobs and were all following online conspiracy theories. Nathaniel was the victim of a heart attack and Stacey resigned over a disagreement about Covid-19 vaccination requirements.

Australian correspondent Murray Olds says the motive behind their execution plan is still unknown.
