Detectives from the Homicide Squad are today releasing CCTV and appealing for further information following the fatal shooting of a 21-year-old man in Wollert in July.
Police received information to suggest that Athan Boursinos' murder was sanctioned by a New South Wales based organised crime syndicate, with the offenders travelling to Melbourne from NSW in the days prior.
Police believe that the two males and the white Volkswagen SUV depicted in the CCTV footage are linked to the murder.
The complex police investigation is ongoing, including inquiries into the deceased's alleged organised crime connections.
Boursinos was approached by unknown males in a laneway behind a Champions Parade residential address shortly before 9am on Thursday 31, July. He was then shot several times.
He was declared deceased at the scene.
The offenders fled the scene in a waiting Nissan Patrol, which was later found burnt out on Amery Street in Reservoir around 9.15am.
The Patrol had been stolen from a Reservoir address in June.
The group of men then got into a grey Volkswagen Golf, previously stolen from a Hampton East address in March.
The Golf was located burnt out on Rosehill Boulevard in Mickleham around two hours later. Detectives believe the men then got into a waiting silver BMW sedan.
Investigators are today releasing CCTV of two men and a vehicle that investigators are seeking to identify in relation to the murder.
Police believe the incident was targeted but are still to determine the motivation behind the attack.
Anyone with information that could assist investigators is urged to contact Crime Stoppers on 1800 333 000 or submit a confidential report online at www.crimestoppersvic.com.au
Quotes attributable to Detective Acting Superintendent Mark Hatt:
"Intelligence leads us to believe these men travelled down from New South Wales prior to Athan's murder, which suggests this is a murder linked to organised crime entities based in that state.
"We are still working to establish the possible motive, although we have several lines of enquiry underway. Athan's various connections to organised crime add a greater level of complexity to the investigation.
"If you have any information regarding the movements of the vehicles prior to and after the shooting, including those who may have been driving them, now is the time to come forward.
"If you believe you have any information relating to the men who may have travelled down from New South Wales to carry out this murder, now is the time to speak up."
