Over the past two days, law enforcement has intensified its efforts to gather new evidence regarding the disappearance of a 41-year-old individual last December.

Authorities have focused their investigation on 315 specific sites within Andamooka, an isolated opal mining town situated in the South Australian outback.

The search operations extended to include mine shafts and abandoned dig sites; however, no new evidence has come to light.

In a development yesterday, a vehicle of particular interest was confiscated and is currently undergoing forensic analysis.

Police remain open to the possibility of revisiting the area as they persist in their search for the missing mother.

In previous efforts, they have investigated surrounding bushland and even examined a septic tank at a home in Andamooka for potential clues.

That search had to be abandoned due to weather conditions, but police continue to hunt for clues about Graf’s disappearance.

Graf was last seen in the early hours of Friday, December 12.

She left the Roxby Downs hotel with a friend just after 12.20am and drove towards Andamooka in her white 2012 Ford Territory, SA registration S254BCX.

Graf collided with a kangaroo a short distance from the Andamooka Township, but continued on to visit a home in the town’s north-west.

She left just before 2am to drive the short distance home, but never arrived.

She was last seen driving along Dunstan Drive, Andamooka.

Her partner and a friend found Graf’s Ford Territory was found perched on a dirt mound near the Blue Dam east of Andamooka just after midday on December 12.
