Fourth murder charge likely over Vic death

A fourth person is expected to be charged with murdering Melbourne man Paul Costa, found dead in a designer suit at a suburban park.

A 20-year-old Cranbourne North man is due to appear via video link in the Melbourne Magistrates Court on Friday to be charged with murder, police say.

Three teens - aged 16, 17 and 18 - have already faced court charged with murdering the 43-year-old, who was found wearing a Zegna suit and shoes at Dunstan Reserve at Brunswick West in July.
