A Chinese man has allegedly killed his mother, father and brother with a hammer and knives inside their Sydney home.
Jacky Amazing Feng, 32, was arrested at the scene in Rosemeadow on Sunday afternoon and later charged with three counts of murder, and one count of attempted murder.
The only survivor of the alleged attack, another one of Feng’s brothers, 30, called police at about 1.30am, and emergency services arrived at the property to find him and Feng’s mother, 65, and father, 64, badly injured, and a third brother, Justin Feng, 25, dead inside a granny flat.
The mother died at the scene, and the father was rushed to hospital with serious blunt force head injuries, but could not be saved. The injured brother has since been released after being treated at Liverpool Hospital.
Feng arrived back at the home in a silver Subaru SUV at about 2.30am and was taken to hospital for forensic and mental health checks before being charged on Sunday night.
He was filmed leaving the crime scene in handcuffs, and in the back of a police van wearing a forensic suit.
NSW Police Superintendent Grant Healey said the crime scene was “extensive” and “very grisly” when speaking about the investigation, and that police suspect more than one style of weapon was used.
“Police were confronted with a very bloody scene. Blunt force trauma is always horrendous for people to confront, and any edged weapon attack is horrendous to confront,” he said.
“So police and ambulance did a fantastic job in very trying circumstances.”
A neighbour told 7News he didn’t know much about the family except that there were three brothers, and one was “troubled”.
Feng was refused bail and will face Campbelltown Local Court on Monday.
The investigation is ongoing and a crime scene remained in place on Sunday night.
