In the Sydney Morning Herald - according to a link on exjwreddit it seems that there is a jw connection to this dreadful tragedy.
It is a long article and I quote a couple of sentences and the headline.
Headline
'Peter didn't snap. He thought this through': Father of shooting victims speaks'
First paragraph
The grief-stricken father of four children shot dead in their beds on a West Australian farm says their grandfather, who pulled the trigger, "did not snap" but had been "thinking this through for a long time".
Part way down
The bodies of Mr Miles and his wife Cynda, his daughter Katrina, and his four grandchildren Taye, Rylan, Ayre and Kayden Cockman, all of whom had autism, were found shot dead on a 30-acre property in Osmington on Friday.
Further down (statement by father of dead children - and ex son in law of believed killer)
While Mr Cockman believes the Miles family's own struggles were the catalyst for the murder-suicide, he said he had experienced his own battles with the family, including over the custody of his children since his divorce from Ms Miles.
"I've had so much anger ... ever since I was cut off from my kids for six months. That was due to Peter and Cynda," he said.
Twenty something paragraph (26?)
Mr Cockman said he had been supported by his family and his faith.
"I've got an awesome, powerful strong family,'' he said. ''They get their strength from Jehovah and so do I."

It does seem on the face of it that there may be a jw/exjw situation - does anyone on here know any more?
