Investigators are appealing for information as a homicide investigation is launched following a fatal crash on the state's north coast earlier this year.
Shortly after 5.45am on Saturday 24 February 2024, emergency services were called to Back Channel Road, Wardell, following reports of crash.
Officers attached to Richmond Police District attended and located a blue Mazda BT50 utility that had left the roadway and crashed.
All occupants of the vehicle died at the scene and have since been identified as driver Mark Dodds (36), and passengers Sophie-Lee Fullagar (33), Benjamin Watego (50), and James Doherty (42).
Detectives from Richmond Police District and the Crash Investigation Unit commenced inquiries into the incident under Strike Force Land.
Following extensive inquiries, detectives determined a second vehicle is believed to have been involved in the incident.
Richmond Police District Commander, Superintendent Scott Tanner, said investigators need those in the second vehicle to come forward.
"Information provided to police indicates that the vehicle involved is an early 2000s-model silver Toyota Corolla sedan bearing stolen number plates," Supt Tanner said.
"We believe the occupants of that vehicle would have information crucial to this investigation, and it is essential that they come forward and speak with detectives.
"I appeal for those in that car to contact Lismore Police or Crime Stoppers, and callers can remain anonymous if they wish.
"My detectives are working to provide answers for the grieving families of these people, and we know there will be people in our community that have information which will assist investigators," he said.
Anyone able to identify the occupants of the Toyota is urged to contact Lismore Detectives on 02 6626 0599 or Crime Stoppers on 1800 333 000.
