Police said there was a history of domestic violence allegations, however, there were no reports in the past few years.

Residents told 9News that the family have been living at the home for more than 40 years.

“[It is] a quiet street, you would never think something like this would occur here,” a resident said.

“There were no indications that something like this would occur up there.”

“I can’t say I would have expected something like this.”
