A 24-year-old man has been charged with five counts of murder after three little girls, their mother and grandmother were found dead in a Perth home.
The bodies of Mara Quinn, aged in her 40s, her three-year-old daughter Charlotte, two-year-old twins Alice and Beatrix, and their grandmother were found at a Bedford home, in Perth's east, on Sunday.
The Bedford man turned himself in at Karratha police station, some 1500 kilometres north of Perth, prompting police to visit the Coode Street home where they discovered the bodies about midday.
It is believed the man also lived at the home.
He will appear in Perth Magistrates Court via videolink from Karratha Magistrates Court later on Monday.
A bouquet of red roses with a card saying "rest in peace, neighbours" has been placed against a light pole near the house.
According to her Facebook page, Mara Quinn became engaged in August 2014 and had her first child in March 2015.
Records show she bought the family's home in 2008.
It comes after the shooting deaths of three adults and four children, all from the same family, in Osmington in regional WA in May, and the murder of a mother and her 15-year-old daughter and eight-year-old son at Ellenbrook, in Perth's northeast, in July.

Deputy Premier and Heath Minister Roger Cook said it was not yet known whether there was a common cause between the three tragedies, but added that mental health was his most challenging portfolio and the situation seemed to be getting worse.
"We have limited resources, we are constantly looking at new ways that we can apply those resources to provide the appropriate level of support," Mr Cook told reporters.
"I want everyone just to hug their kids, hug their family today. This is a horrible event and it's very upsetting."
