Three guns found at a rural West Australian property, where seven relatives - including four children were killed in a suspected murder-suicide, belonged to the grandfather.
Police on Saturday said they believed property owners Peter and Cynda Miles, aged 61 and 58, were among the dead at the Forever Dreaming Farm in Osmington, northeast of the popular tourist hub of Margaret River.
The others are believed to be their 35-year-old daughter Katrina Miles and her four children - daughter Taye, 13, and sons Rylan, 12, Arye, 10, and Kadyn Cockman, eight.
All of the deceased, who are yet to be formally identified, suffered gunshot wounds.
WA Police Commissioner Chris Dawson would not say whether all three guns were discharged, but did reveal the firearms were licensed to Mr Miles.
"Police do not believe any other person is involved with these crimes," he told reporters.
"Police are not searching for any other suspect."
Asked if the two-minute emergency call made from the property at 5.15am on Friday was the reason police were so quickly able to rule out a gunman was on the loose, Mr Dawson said: "That's not for me to expand on now."
He said police knew whose phone the call was made from but would not confirm whether it was Mr Miles.
Mr Dawson clarified only one body was found outside the property's buildings.
One woman was located dead inside the main house, while another woman and four children were discovered inside a converted shed.
The commissioner was also quick to defend the actions of the two local police officers who arrived first at the scene just after 6am on Friday.
"I'm very confident as I stand here that the call and response that they made was exactly the same as what I would have done."
Mr Dawson said police were "some way" from completing their investigation and the examination of the crime scene would still take several days.
The family on Saturday released a statement saying they were devastated.
"We are stunned and still trying to understand how this could happen," the statement said.
"We respectfully ask that the community refrain from speculating on the circumstances surrounding this tragic incident.
"We thank the community for their support and ask that our privacy is respected as we grieve."
The extended family is fully co-operating with police, while the children's father is also getting the support he needs.
"Many people who know the family are deeply feeling the loss and the community, understandably, do want answers," Mr Dawson said.
Flowers, tributes and cards can be left at the Margaret River Community Resource Centre.
"This is a strong, connected community and I know that we'll all support each other and we'll get through this together," Augusta-Margaret River shire president Pamela Townshend said.
