Mr Hutchings had recently been released from prison but family said he was working hard to get his life back on track, looking at work in the gardening or fitness industries.
«He was a beautiful person and looked after his mum and his family and cared about his children and just wanted to progress to a better life,» said his cousin, Sharni Hutchings.
Police executed search warrants in Doncaster and Park Orchards on Sunday afternoon.
Four men were arrested late on Sunday.
A 56-year-old man from Doncaster East was charged with murder and aggravated home invasion.
Three others — a 22-year-old and 18-year-old both from Doncaster East and a 24-year-old Park Orchards man — were each charged with aggravated home invasion and assault.
They will face Melbourne Magistrates Court on Monday morning.
Paramedics said they treated Mr Hutchings for an upper-body injury on Saturday morning. He was rushed to The Alfred hospital, but later died.
The shooting was across the road from the Corpus Christi Aged Care centre, where people had to move behind police tape to visit their relatives on Saturday.
It was also close to a children’s park in Carlson Reserve, where a group of young people spent the morning training at the sports oval.
Al Wong said he played cricket at the reserve most Saturdays. «It’s very, very different from what you’d normally expect in this area,» he said.
«This area is a very family-orientated place. There’s a playground, the tennis club [and] a lot of university students live around here as well.»
Police spent most of Saturday at the scene, combing the apartment for clues.
Police are still appealing to for witnesses. Anyone with information can call Crime Stoppers on 1800 333 000.
