The daughter of two of the Queensland cop killers has broken her silence in an astonishing interview about her parents and uncle.
Nathaniel, Stacey and Gareth Train shot dead Constables Matthew Arnold, 26, and Rachel McCrow, 29, as well as innocent neighbour Alan Dare, in a siege at a property in Wieambilla in December.
They also shot two other police officers who were able to flee with their lives.
Specialist officers then shot the three Trains dead.
Nathaniel and Stacey Train had two children together before Stacey left him for his brother Gareth.
One of those children spoke to 9 News about her “normal” upbringing her life was turned upside-down by the horrific massacre.
“Grieving three of your family members is hard enough and then finding out what they did,” she said.
The first section of the two-part interview airs on Sunday.
Stacey’s family previously revealed how the former teacher became entwined with the Train brothers.
She grew up in a churchgoing family before branching off on her own to the independent church run by the brothers’ father, Ronald Train.
One of Stacey’s relatives, who wished to remain anonymous, told The Guardian she was a quiet girl and often the odd one out.
They revealed that they “wish she never” attended the Train church, claiming “this would have never happened”.
It was in this church that she met Nathaniel Train, who she married in her late teens and had two children with.
She later left him for his brother Gareth.
“I knew Gareth was an a**ehole when he took over his brother’s wife,” the relative told the publication, adding it was “all downhill from there”.
“Now she is dead because of them,” they said.
Stacey became estranged from her family, but the relative claimed her mother would still call her every year for her birthday – but would quickly hang up if Gareth answered the phone.
The split and relationship with Gareth caused a rift in the Train family – particularly between the brothers and their father, who was a pastor for 27 years at a church which has strict views on marriage.
Nathaniel and his father had not spoken for 23 years.
But Ronald told A Current Affair he had “absolutely no idea” Gareth and Stacey had struck up a relationship and were married.
“My second son Gareth is on the Asperger’s line. Very difficult to control, very overpowering,” he said.
“I just think he took over that relationship that Nathaniel and Stacey had.”
Police had previously considered whether Stacey had been forced into opening fire on police by the Train brothers, but it soon became clear that was not the case.
“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.”
