The dead bodies of two sisters aged six and 10 were reportedly discovered by their own dad when he arrived home from work.
The dad found his two deceased daughters inside his Bogdanich Way home in Madeley, north of Perth, about 5.50pm (local time) on Friday, according to The West Australian.
A woman thought to be the mum of the two children was found at the car park of nearby Mullaloo Beach with self-inflicted wounds about three hours later, according to WA Police Assistant Commissioner Paul Steel.
A neighbour detailed the dad’s grim discovery after speaking to the grandfather of the young sisters.
“He (the grandfather) told me his son came home from work to find his little girl dead on the floor. When he called police they told him not to touch her, but by that time he'd found the other little girl in the laundry,” she told the publication.
The neighbour said the family were originally from Bosnia and had lived in Australia for more than 20 years, with the mum working as a nurse and the dad an engineer.
Yahoo News Australia has contacted Western Australia police for comment on the matter.
Earlier police confirmed the dad was assisting in their investigation and the woman, believed to be the girls’ mother, was under police guard in hospital receiving medical treatment.
“As a result, she is not able to be interviewed at this time,” Asst Comm Steel said.
“This is a tragic event and our heartfelt condolences go out to the friends and family of the children.
“Tragically for first responders, finding the bodies of two young children would have been a terrible thing to have to go through.”
Asst Comm Steel said the cause of the girls’ death and factors leading up to it would be investigated as part of a meticulous forensic investigation.
He said there was no information to indicate there was any ongoing threat to the public.
