Police allege that after the shooting the killer drove off in Sabeckis' vehicle, which was then crashed into bushes and a fence further along Tuit Rd.

He was then seen running from the vehicle across paddocks.
Police found a sawn-off shotgun and jacket in the area.
They believe the gun was used to kill Sabeckis and the jacket belonged to the killer.
The shotgun and another firearm, were stolen during a break-in at a house at Aldinga Beach south of Adelaide on New Year's Eve - just days before Sabeckis was murdered. The house was then burned down, destroying potential forensic evidence.
DNA believed to belong to the killer was taken from several items.
It was never matched to anyone until a change in New Zealand legislation allowed overseas law enforcement agencies to apply for access.
