A MUM and her four autistic children are among seven people found shot dead in the worst mass shooting in Australia in 22 years.
But who were the victims, where did the attack take place, and what have the police said?
Who was shooting victim Katrina Miles?
Katrina Miles was found dead alongside her three sons and daughter, aged eight to 13, in a "horrific" suspected murder-suicide at a farm.
Cops swooped on the rural home in Osmington, Western Australia, after a man "connected to the property" raised concerns about the occupants.
Once inside they discovered five bodies inside the property, and another two outside. All had died from gunshot wounds.
In a Facebook post last month, Katrina wrote: "My ex does not stop stalking me," the website reported.
Who were the victims?
The victims of the atrocity have been named were Katrina Miles and her four kids - three sons and a daughter in what is thought to be a murder-suicide.
Cops are now focusing their attention on the grandfather Peter Miles, husband of Cynda Miles.

Police are also probing a phone call a man made to cops at 5am on May 11.
The children are thought to be aged eight to 13.
In a Facebook post last month, Katrina wrote: "My ex does not stop stalking me," the website reported.
And news.com.au reported a social media post from someone who knew the family stated: "Lovely people, but crazy ex-husband."
What did Katrina's friends say?
Neighbour Felicity Haynes said Katrina's parents moved to the region to build the sustainable farm for their daughter and her grandchildren. It is not yet known who the two other victims are.
Katrina's friends told The Australian she was a devoted mum who "worked tirelessly to provide them (her kids) with everything they need."
One said: I always admired her for her strength. The kids were kind, gentle, smart and beautiful children."
Western Australia police commissioner Chris Dawson: "I can only say at this point in time, we have no information to raise concern about wider public safety issues.
