Police are seeking public assistance to locate a vehicle of interest in the investigation into the murder of Chris Robertson.
The vehicle, a grey Mitsubishi Triton utility XTF976, was seen at the Lonsdale premises on Sunday 28 September – the day after Chris was last seen alive while celebrating with friends.
Major Crime detectives have spoken to the registered owner of the vehicle, who is not believed to be involved in the murder, and they are assisting with the investigation.
Major Crime Investigation Branch officer-in-charge Detective Superintendent Darren Fielke said the vehicle has not been seen since Chris was located on Tuesday 30 September.
"We are seeking information from anyone who knows who may have been using the vehicle at the time of Chris' death and the current location of this vehicle,'' he said.
"We believe it is likely the vehicle was used to transport Chris to 55 O'Sullivan's Beach Road at Lonsdale on the morning of Sunday 28 September.
"Locating the vehicle is crucial to the investigation as it could provide valuable forensic evidence that will assist the investigation.''
A post-mortem examination has revealed Chris Robertson died as a result of injuries received after being severely assaulted.
Det. Supt. Fielke said the murder investigation was following several significant lines of inquiry.
"As a result of investigations since Chris was found and information received via Crime Stoppers we have spoken to a number of witnesses and this has helped us piece together his movements between 27 September and 30 September,'' he said.
''We are confident there will be a resolution in this investigation, and I would urge anyone in a position to assist us to do so.''
Police urge anyone with any information on the vehicle or any information about Mr Robertson's murder to contact Crime Stoppers immediately on 1800 333 000 or report online at www.crimestopperssa.com.au
