Troubling new details about the love triangle between cop killer brothers and their lover have emerged – as a police officer who miraculously survived the shooting pays tribute to her fallen colleagues.
Stacey, Gareth and Nathaniel Train were killed by a specialist police team in Wieambilla, about 300km west of Brisbane, on Monday after they shot dead two officers performing a missing persons search, as well as a neighbour.
The Train trio’s bizarre love triangle was formed after Gareth ‘took over’ his younger brother’s marriage, according to their father, Ronald.
The brothers became estranged from their conservative Christian pastor father following the breakdown of Stacey’s relationship with Nathaniel.
The siblings and Stacey then became increasingly obsessed with anti-authority conspiracy theories.
One of Stacey’s family members claimed Nathaniel – an ex-school principal – was a ‘quiet’ man who would still be alive if he hadn’t become entangled with ‘control freak’ Gareth.

‘I knew Gareth was an a***hole when he took over his brother’s wife,’ the family member told The Guardian.
‘It was all downhill from there. Now she is dead because of them.’
Troubling details about their relationship have emerged, including claims from a local that they saw Gareth dragging Stacey up a flight of stairs by her hair.
Stacey’s parents are understood to have lost contact with their daughter years ago, with one family member blaming the rift on Gareth’s ‘controlling’ behaviour.
Her mother attempted to make contact with her daughter every year on her birthday, but would swiftly hang up if Gareth answered the phone.
It comes as a visibly emotional Constable Keely Brough, 28, paid respects to her fallen colleagues at a vigil in Illoura Village in Chinchilla on Friday night.
The constable had on Monday texted her family and police her goodbyes after desperately escaping into surrounding bushland to evade the killer Train trio.

The trio fired bullets and lit fires in an attempt to flush her out after her colleagues Matthew Arnold, 26, and Rachel McCrow, 29, were shot dead execution-style.
A fourth officer, Randall Kirk, was shot in the leg but managed to escape the Wieambilla fortress while innocent neighbour Alan Dare was not so lucky and was shot in the back after he and another neighbour went to investigate.
On Friday, more than 400 people gathered to pay respects to the four victims of the suspected ambush as locals in Chinchilla laid flowers and lit candles.

Assistant Commissioner Charysse Pond pulled the young officer into a tight embrace at the vigil as similar tributes were seen in the nearby town of Tara.
It has been discovered Stacey and Gareth had transformed their isolated rural property into a violent playground of secret cameras, ‘kill zones’ and barricades designed to help the trio ambush the unsuspecting officers.
NSW Police issued a missing person alert for Nathaniel on December 4 and received a tip saying he was staying at the Wieambilla property.
Police are now considering if that tip call come from Nathaniel, Stacey and Gareth as a way of luring officers into their trap.

Investigators found two foxholes concealed by scrub complete with living quarters and a campfire that had been dug into the ground ahead of time.
Forensic officers have only just started to comb the property for evidence after the bomb squad cleared the home of any further booby traps.
The Trains had been prepared with a stash of weapons and ammunition, later stealing two Glock pistols from the bodies of constable Arnold and McCrow.
Shortly after the constables were shot dead, Gareth and Stacey ranted about ‘devils’ and ‘demons’ in a now-deleted video on their YouTube channel.
Just hours after their deaths, the couple recorded themselves huddling in the darkness and boasting about the cold-blooded killings.
In the clip, seen and verified by Daily Mail Australia, Gareth said: ‘They came to kill us and we killed them’. He also refers to the cops as ‘devils and demons’.
Stacey Train finishes the video by saying ‘we’ll see you when you get home’ and ‘love you, Don’. It is unclear who precisely they are referring to.
Nathaniel Train does not feature in the clip. About three hours after the video was published, the three Train family members were shot dead by tactical police.

In a video uploaded to YouTube the day before the fatal shooting which was re-posted on Friday, Stacey revealed she has become recently estranged from her two adult children
On the deleted YouTube channel, Gareth and Stacey Train use the names Daniel and Jane – their middle names. Their channel only had six subscribers and 10 videos.
Just one of the clips had been viewed more than 50 times.
In a video uploaded to YouTube the day before the fatal shooting, Stacey revealed she has become recently estranged from her two adult children.
She narrated a letter in the video that she wrote to a fellow conspiracy theorist.
‘I know the pain of losing children. Recently, my husband and I lost both our adult children when they chose the world, rejecting us and the narrow path to take the wider road that their partners and friends are on,’ she said.
‘This is a pain that will only be healed in heaven.’
Another bizarre clip titled Bullyman shared a day before the siege features a robotic voice believed to be Gareth reading out a missing person’s report for Nathaniel.
It opens with the title screen from the TV program Cops before showing a photo of Nathaniel shared when he was reported missing by NSW Police a week prior.

The voice then reads out the police missing persons report before making a bizarre rant with references to the younger Train brother.
‘I see there was no mention of this missing man being a whistleblower on high level corruption within the New South Wales education department,’ the voice said.
The video refers to ‘connections to the NSW Police organised crime syndicate and the fixated persons branch’ and an ASIO officer.
He also had a message for police as called out several individual officers from NSW and Queensland. Daily Mail Australia has sought comment from police.
The disturbing videos emerged as Queensland Police announced the two slain constables will receive full police honours at a funeral service on Wednesday.
A GoFundMe for the good Samaritan, Mr Dare, has raised more than $70,000 for his widow, Kerry.
