Police have released CCTV vision detailing the moments before the shooting death of Mahmoud Hamzy in Sydney's south-west last October and possible vision of one of the gunmen afterwards.
The vision from October 29 shows three people getting out of a white Nissan Tida on Bardo Circuit in Revesby Heights before they are seen creeping along the street in dark hooded jumpers and pants.
The three then run into a driveway and out of sight of the camera, which is installed in another home.
Police say that, at that point, a number of people were sitting in a garage at the end of the driveway, including Mr Hamzy, 25, and a 24-year-old man who was later treated for serious gunshot wounds to his leg and stomach.
“The three gunman have fired bullets at the people inside the garage; two of them have been hit,” a NSW Police pokesman said.
The vision shows a fourth person driving the car down Bardo Circuit before the three gunman jump back in.
“The three gunman then run out of the garage and have got into the car and the CCTV depicts what appears to be a gun being fired from the car, like a passing shot back towards the garage,” the spokesman said.
Emergency services were called about 12.30am.
Both injured men were taken to Liverpool Hospital where Mr Hamzy was pronounced dead.
Shortly before 1am, CCTV shows a person walking into a deserted Hurstville railway station wearing a dark hooded jumper and tracksuit pants, white shoes and carrying a small plastic bag.
NSW Police say they believe this person can help with inquiries and that “they may be one of the people involved in the shooting”.
Commander of the Homicide Squad, Detective Superintendent Mick Willing, said members of the public had already provided some important information to detectives from Strike Force Roxana, which was formed to investigate the case.
“We want to thank the community for the support they have provided on this case to date, and ask them to contact us again - either via the anonymous Operation Talon phone and SMS lines or through Crime Stoppers,” Detective Superintendent Willing said.
“The community play a crucial role in helping us investigate serious crimes and we need their continued assistance to ensure we track down the people responsible for this cold-blooded murder.”
The Nissan Tida was found burnt out in Jamison Park in Penrith a few hours after the shooting, and investigators have also have two firearms that have been forensically linked to the incident.
A third gun is yet to be recovered.
Police ask anyone with information to call Crime Stoppers (1800 333 000), the anonymous Operation Talon phone (1800 802 980) or SMS (0448 990 101).
