CCTV released in bid to find Sydney student's shooter

Police have released new vision as they ramp up a search for the gunman who shot dead a 24-year-old in south-west Sydney. 

Barber and university student Marvin Oraiha was killed outside his home in Elizabeth Hills in May. 

Police believe the shooters used a white Audi as a getaway car, before dumping it in Green Valley.

They then got into a Toyota Prado before setting it on fire in Bonnyrigg Heights. 

Police are now looking for a third getaway car, believed to be a Honda Accord.

Criminal Groups Squad detectives released CCTV overnight showing two thin men dressed in dark clothing and balaclavas running down Cordelia Crescent in Green Valley before getting in the Prado and driving away.

The Prado was found burned out in Lewis Street in Bonnyrigg Heights while the Audi was found in Cave Close in Green Valley.

Anyone with information or dash cam vision was urged to come forward. 

CCTV released earlier in the investigation showed Oraiha's girlfriend, mother and sister walking inside after school pick-up before he was gunned down in the driver's seat of his car.

The shooting left him slumped over in the car and riddled with bullet wounds.

"I think it is as bad as it gets, it is an awful crime," detective acting superintendent Virginia Gorman said.

"It is shocking for the family, for the people who live in that street, for his girlfriend and generally the community."

Gorman said Oraiha's girlfriend was not in the car but had been with him shortly before the shooting.
