Pictured: The smirking face of evil cop killer Stacey Train
The 45-year-old female cop killer of the Doomsday cult trio was shot dead 'running from the house carrying a rifle'.
Daily Mail Australia can exclusively reveal the three firearms used by Stacey Train, her husband Gareth Train, 47, and her ex-husband, Nathaniel Train, 46, were a shotgun, and a pair of rifles, a .22LR and a 30-06.
The firearms used by the Trains before they stole two police-issue Glock pistols from the bodies of slain constables Rachel McCrow, 29, and Matthew Arnold, 26, were described by one cop as 'farm guns ... not the sort of weapon you'd use to win a shoot out and escape'.
Chilling new details have also emerged about Ms Train's involvement in the shootout at the remote Wieambilla property three hours west of Brisbane which also claimed the life of Good Samaritan neighbour Alan Dare, 58.
Police originally considered whether she was forced into opening fire on police by the two brothers.
It's been revealed Ms Train, alongside her husband and brother-in-law stood over Mr Arnold and Ms McCrow lying on the ground and shot them dead from point-blank range. The trio were shot dead by tactical police six hours later.
The three rifles used by Stacey Train, her husband Gareth Train, 47, and her ex-husband, Nathaniel Train, 46, used in the murders and the deadly gun battle were a shotgun, a .22LR and a 30-06 rifle (scene at the Wieambilla property is pictured)

'There was a thought that Stacey may have been an unwilling participant but she was shooting at police with the best of them,' a police source told The Australian.
'She got shot and went down and was still shooting at police as she was laying on the ground. She was then shot and killed.'
Police are now investigating whether the Trains were preparing to ambush officers.
The trio had planted cruel obstacles like scraps of metal and large tree trunks to trick the unsuspecting officers into running towards planned 'kill zones' where they could be shot at in the open.
One of the trio was wearing a ghillie suit.
A network infra-red motion sensors, not reliant on centrally connected electricity were designed to sound alarms and alert the Trains of anyone entering the property.
Police are also investigating an eerie detail about the Train trio who vanished from the property just weeks before Monday's siege and shootout.
Following one of two fires at the 43ha property on Wains Road at Wieambilla, three hours west of Brisbane, firefighters arrived to discover the wooden house occupied by Stacey and the two Train brothers empty and the grounds abandoned.

The police heroes who who put their lives on the line to rescue a fellow officer from certain death, and bravely retrieved the bodies of two slain colleagues, were not from the crack special operations team but country town coppers.
Awaiting the 12 brave officers at the remote Wieambilla property in Queensland was a network of booby traps rigged with secret cameras and motion sensors all leading to 'kill zones' - with police now all but certain the attack was premeditated.
Stacey Train, her husband Gareth and brother-in-law Nathaniel Train, had been holed up in the Wains Road house armed with an array of weapons.
The paranoid, conspiracy-driven trio had a stockpile of ammunition, rifles and a shotgun, with one even wearing a ghillie suit to sneak up on officers.
Hidden cameras had been installed in trees surrounding the homestead while infra-red motion sensors alerted the main house if anyone had entered the booby-trapped fortress.
The Trains had planted cruel obstacles like scraps of metal and large tree trunks to trick the unsuspecting officers into running towards planned 'kill zones' where they could be shot at in the open.
When the cold-blooded family fatally gunned down two young constables at their remote Queensland property on Monday, the call went out for police from around the Darling Downs area to urgently provide back-up while the Special Emergency Response Team (SERT) was being readied to deploy.
They arrived to see the bodies of two officers lying in the driveway of the home, and another terrified young officer hiding somewhere out in the bush where a fire had been lit to flush her out, as she desperately texted loved ones in the expectation she too would be killed.
SERT members - who eventually killed the brothers and wife who were holed up in the house - have been quick to praise the efforts of the country officers, whose day-to-day duties are more usually along the lines of traffic infringements and petty crime, not deadly gunfights like the one they encountered on Monday.
A local resident told Daily Mail Australia that a former Wains Road neighbour had made at least seven reports about suspicious fires on the property over a six-month period, alarmed by the possibility of the blazes igniting major bushfires.
The same former neighbour also reported the sound of gunshots coming from the Train property or nearby.
Mrs Train was a respected school principal before falling under the spell of conspiracy theories before being shot dead alongside husband Gareth and her brother-in-law, ex-husband Nathaniel at their property in Wieambilla, about 10.30pm on Monday.
The firefight came after the camouflage-clad trio killed Ms McCrow and Mr Arnold, who'd arrived at the remote home looking for Nathaniel, who was reported missing a year ago.
Gareth and Stacey Train had religiously stayed off the grid after the paranoid pair become obsessed with extreme conspiracy theories - including anti-vax beliefs that saw her quit her job as head of curriculum at nearby Tara Shire State College.

Almost no photos exist of the killer couple but Daily Mail Australia has obtained an image of Mrs Train posing with students when she was the principal at Quinalow P-10 State School, north-west of Brisbane, at an awards night in 2010.
Wearing a pearl necklace and patterned beige dress, she smiled awkwardly for the camera in the rare picture.
Quinalow is one of a long list of primary schools in Queensland where 'Mrs Train' had stints as principal.
All three killers who were locked in a bizarre love triangle had worked for Queensland Department of Education in the last 15 years, but all had quit by the time of the savage ambush on Monday.
Mrs Train was also principal at Herberton, Mitchell and Proston State Schools and others in far north Queensland around Mount Isa, before taking up a post as head of curriculum and a teacher's aide at Tara Shire State College in 2019.
But the staunch anti-vaxxer quit that job in December rather than take a Covid jab.

Gareth Train also resigned from the department in May 2016, where he had reportedly worked as a school groundsman.
His brother, Nathaniel Train, resigned from the department in March 2020, a spokesperson for the Queensland Government said.
None of them were subject to any Departmental disciplinary proceedings at the time of their departures, and Nathaniel Train went on to work in the school system in NSW's central west.
A former student at Tara Shire State College, told Daily Mail Australia that Stacey felt as if she had to quit her job due to the school's mandatory immunisation policy.
Like her husband and brother-in-law, Mrs Train believed in a range of false conspiracy theories - hers centring around concerns about Covid vaccines.

The former student said Mrs Train was 'her own person, but nice' and lived as something of a recluse - only ever travelling into town in Tara, about 45 minutes from her property, to go to work.
Like many people in the Wieambilla area, the former student heard gunshots on Monday evening and was shocked to learn the shoot-out happened so close to her home.
She said it was 'unsettling' and she felt rattled, but was even more shocked to learn her old teacher was caught up in the incident.
Before the murderous trio moved to Wieambilla, the three of them owned a four-bedroom home together in Millstream, about 150km south-west of Cairns in far North Queensland, which they sold in 2009.
A neighbour from their Millstream days paints a very different picture from the Trains' reputation at school, describing them as 'paranoid' and aggressive' people, who didn't want any attention.
The property, owned by Gareth, who spoke of prepping his home for an apocalypse, and his wife Stacey was well off the grid, had extensive solar panels and water tanks
'They just weren't nice people and showed the potential for just this sort of thing even way back then,' he told Daily Mail Australia.
'They had barbed wire and gates and fences around the property too - that's normal on rural properties like these, but they had surveillance cameras and spotlights and things like that which was a bit out of the ordinary back then.'
He said Stacey and Gareth lived on the property full time, and Nathaniel would stay there on the weekends.
'They had children who would be in the 20s now - they obviously don't live with their parents any more though,' the former neighbour added.
After they sold the Millstream property in 2009, the trio formally changed their home address to the address of Proston State School - where Mrs Train worked as the principal for a short time.
