Queensland police had “no red flags” associated with the Train family ahead of last week’s fatal shootout in Wieambilla. 

Deputy Commissioner Tracy Linford this morning told a media briefing the agency had “very little history” with the group when four officers were sent to the rural property.

She said Nathaniel Train was subject to an outstanding warrant for a border breach from NSW in December last year.

Police had already tried unsuccessfully to reach him about the matter at the address in August.

Prior to that, Train only had a 2014 driving offence in the state.

Meanwhile, Gareth Train had only previously been subject to a decades-old offence for possessing a firearm with an expired licence.

“In terms of Stacey Train, we have no criminal history or intelligence holdings on her,” Deputy Commissioner Linford said. “We knew very little about the Trains.

“There was nothing that could have caused a particular flag for our members who attended on that day last Monday, that would have raised any particular concerns about those individuals.”

NSW Police will help their Queensland counterparts in collating information on the group, including email exchanges and phone calls.

Thousands of colleagues and dignitaries yesterday gathered to farewell slain constables Matthew Arnold and Rachel McCrow at a memorial in Brisbane.

Neighbour Alan Dare, who was also killed when he arrived to investigate smoke and gunshots at the property, will be farewelled at a service held tomorrow.
