Three teens have been charged with murdering a Melbourne man found dead in a designer suit, with more people expected to be prosecuted by police.
A passer-by found Paul Costa, 43, at a Brunswick West park on July 3 wearing a Zegna suit and shoes and on Thursday detectives arrested two males, aged 17 and 18, at Thomastown.
The 17-year-old appeared before a Children's Court on Thursday charged with murder.
A short time later an 18-year-old man, who cannot be named for legal reasons, faced the Melbourne Magistrates' Court, also charged with Mr Costa's murder.
Prosecutors say Mr Costa was murdered on July 2, a day before his body was discovered.
Both teens have been remanded into custody to return to court for a committal mention on January 15.
Prosecutor Ashleigh Harrold says other co-accused are yet to be charged.
Police are still analysing CCTV footage and some mobile phones have been seized which could yield more clues, she said.
"It was a very complex scene, I'm instructed," she told a Children's Court.
Another teenager, 16, was arrested at Newcastle in NSW and is expected to be extradited to Victoria on Friday on one count of murder.
The victim's family say Mr Costa was a gentle man and thought he may have been on a date on the night he was killed.
"He had a heart of gold, I don't know anyone who'd want to hurt him," his sister Sandra Di Giorgio told reporters previously.
The teens were supported in court by family members.
The victim's family was also in court for the brief filing hearings.
