“It’s a very extensive crime scene, so we haven’t recovered a weapon at the moment, but we’re systematically working through the granny flat out the back and then we’ll go through the house.”

Police believe the 32-year-old who was arrested at about 2.30am after arriving at the home is the son of the man and woman aged in their 60s and the brother of the two younger men in the family.
Healey said the family were not well known to police and have never interacted with police in relation to domestic violence.
He was not willing to give any information regarding what police believe happened in the home before the deaths.
“It’s very early in the investigation, so I can’t speculate,” he said.
Healey was unwilling to confirm reports the attack was carried out using a hammer as investigators are yet to recover the weapon.
“Whilst we can say it’s a hammer, we’ve got to be 100% sure. We’ll take our time and investigate it properly,” he said.

He did confirm no firearms were used but said they believed multiple weapons may have been used based on the injuries.
“…Looking at some of the injuries, we suspect there may be more than one style of weapon,” he said.
“We think that there’s a bladed weapon involved, as well.”
A third son in his 20s has been confirmed as the fourth person injured in the assault.
He was taken to Liverpool Hospital but has since been released.
The 61-year-old woman was located first by police who took her into the yard and tried to administer first aid.
They then went back inside the house and found a 64-year-old man who was still alive but had serious head injuries.
A 37-year-old man was later found dead in a granny flat at the back of the property.
The critically injured 64-year-old man died after being taken to Liverpool Hospital.

The 32-year-old man arrested at the scene was taken to Campbelltown police station.
He is yet to be charged.
