Police say Reynella woman Rachael Moritz has contacted them and is no longer considered missing.
The 20-year-old was last seen several weeks ago when she left her home.
It is believed she may be interstate.
Police say her car was used in the shooting murder of Jason De Ieso at his Pooraka workshop in November.
The car was later found burnt-out at Kangarilla but police say Ms Moritz was not at the murder scene.
