Teenager arrested after woman and two children killed at Perth home

A mother and two children are the victims of a horrific triple-murder in Perth.

Officers uncovered the gruesome scene in the North-East suburb of Ellenbrook yesterday afternoon.

The mother and her son were found dead inside the home, her teenage daughter was critically injured in the backyard and died on the way to hospital.

A 19-year-old man who is believed to also live at the home has been charged by WA Police.

“A senior homicide squad investigating officer said to me today it is potentially the most horrific crime scene he has ever been called to,” assistant commissioner Paul Steel told reporters in Perth on Sunday afternoon.

A pair of scissors were found in a bush close to the home and they have been sent away for examination.
