“Liam was trying to help him,” Anderson said.
“He was such a decent human being.”
Mr Flame, 20, is alleged to have punched and stomped 26-year-old Liam Anderson to death in northern Sydney early on Sunday while under the influence of MDMA, marijuana and alcohol.
Emergency services had been called to the park on the corner of Pavilion Street and Bridge Road about 6am following reports of an assault.
“It was quite a bloody scene,” Detective Inspector Michael Boutouridis said on Sunday.
The Anderson family were told Liam’s injuries were so severe they should not request to see his body.
Mr Flame has been charged with murder and is in custody, due to next face court on January 29.
