POLICE conducted further searches this weekend to find a missing woman who has been off the radar for more than a year.
Tweed Heads South woman Carol Anderson disappeared without a trace on November 11, 2011.
Senior Constable Duncan King, who now heads the investigation, said police divers searched near Fraser Dr with no luck.
"We conducted a search to make sure," he said.
"Nothing was found."
On Tuesday, November 27, SES crews conducted a ground search as well.
Snr Con King said all avenues of the search had now been exhausted and without fresh information they were at a loss.
Ms Anderson would be 71-years-old.
The Alzheimer's sufferer went missing from the Palms Caravan Park on Dry Dock Rd.
Last year Inspector Darren Steel said Ms Anderson could be on private property, underneath a house or in a shed.
He said it was possible she had become disorientated and taken shelter somewhere and he urged all Tweed Heads residents to check their properties in case Ms Anderson had taken shelter.
Exhaustive land and river searches were conducted with the assistance of the SES, Rural Fire Service (RFS), Volunteer Rescue Association (VRS) and the RACQ Careflight helicopter however the search had to be scaled back when no trace of Ms Anderson was found.
Ms Anderson is described as Caucasian, 160cm tall with a medium build and brown/grey collar-length hair.
She was captured leaving the park on CCTV footage around 1.40pm (NSW) on Friday, November 11 wearing a white dress with shoestring straps.
Police are still appealing for information, if you know anything please contact Crime Stoppers on 1800 333 000.
