Footage capturing the final moments before the execution-style killing of an underworld crime figure could hold the clue to finding all of those responsible for the murder.
Ferenc "David" Stemler was gunned down on a suburban street at Canterbury, in Sydney's inner southwest, on July 27.
The 28-year-old died at the scene from multiple gunshot wounds in an attack police said had all the hallmarks of an underworld hit.
He was the fifth person to be shot on a Sydney street in as many days.
The shootings prompted NSW Police to set up Task Force Magnus to examine the killings, which were believed to be linked to organised crime networks feuding over the city's lucrative illicit drug trade.
Police on Monday released CCTV footage capturing the moment Mr Stemler approached a white Commodore outside his address on Broughton St before he was fatally shot.
Detectives believe the meeting was pre-arranged.
A white Lexus and a dark hatchback are then seen in convoy in Casula on their way to burn out the Lexus, which was used in the shooting.
In the days before the shooting, CCTV also captured a white Lexus - which police say was stolen earlier in the month - arriving at the Casula Central car park on July 18.
The same car was seen being "checked on" by a black hatchback and a dark-coloured hatchback on July 20 and again on July 24.
The Lexus' lights were seen flashing as the keys appeared to be tested.
Just before 9.50pm on July 26, a white Commodore - which police said was likely stolen seven years earlier - entered the car park before leaving in convoy with the white Lexus.
Both cars travelled to the car park of a townhouse a short distance away on Pine Rd, where they waited for about three hours.
Shortly after 1am on July 27, the cars were seen exiting the M5 motorway at Bexley Rd in Kingsgrove, a few kilometres from where Mr Stemler was killed.
A 23-year-old woman and a 27-year-old man have already been charged with murder and remain before the courts.
Homicide Squad commander Virginia Gorman previously said the woman was "most likely a lackey doing tasks" and not the mastermind of the operation.
