Northern Territory Police have released images of two vehicles believed to have been travelling in the vicinity of Angie Fuller when she went missing north-west of Alice Springs on July 9.
The police investigation into the disappearance of Ms Fuller, a 30-year-old mother-of-two, is being treated as a suspected homicide. A search and rescue mission for Ms Fuller was suspended after two weeks.
Northern Territory Police have requested information from the public on the movements of a 1986 camouflaged Daihatsu Rocky without registration plates and its rear canopy removed and a 1998 Silver Nissan Pulsar sedan with Northern Territory registration plates.
Police said they are interested in the movements of the vehicles between January 9 and January 12 this year.
The vehicles, during this time, were travelling on the Stuart Highway north of Alice Springs and the Tanami Road, near the Stuart Highway turn-off to the Tanami Road, and possibly on dirt tracks in the area, police said.
Detectives know where the vehicles are, police said, and are only interested in the movements of the vehicles during this time frame.
Ms Fuller was last seen on the Tanami Road. The search operation in January focused on an area 15 kilometres west of the Tanami Road's junction with the Stuart Highway.
Five weeks after Ms Fuller's disappearance police said they had seized a number of items as part of their investigation.
