Sadar was the eldest of five children and a refugee who grew up in Afghanistan, coming to Australia by boat in search of a safer life.

“We are in shock, we are (going through) a deep pain,” his sister Meena told 9News.

“We cannot explain our pain.”

Masoud and Meena Sadar described their brother as hardworking, saying he would take care of his friends, family and community.

His siblings told 9News their parents are still in Afghanistan and have been hospitalised since hearing the news.

The NSW government is reviewing security at Cumberland Hospital following reports that two men, including the alleged offender, Setefano Mooniai Leaaetoa, had absconded from a mental health facility 10 days earlier.

He has since been charged with one count of murder and two counts of causing wounding or grievous bodily harm with intent to murder over the alleged attack.

The second patient, Luke Francis, allegedly absconded from the same facility within days of Leaaetoa’s escape.

He allegedly attacked a nurse before escaping Cumberland Hospital.

Francis then allegedly stole a car before leading police on a pursuit that ended after colliding with another vehicle in Camden, killing two women.

The Nurses Union has revealed that despite Cumberland Hospital being set to become one of the largest mental health facilities in the country, it only has three security guards on staff at any time to manage the entire facility.
