Mystery of frail woman in her 80s who was dumped at a hospital because she didn't know who she was deepens as she admits she knows her identity but REFUSES to tell doctors

Police have officially closed the case of a mystery woman who was left at a hospital in the Sunshine Coast. 

The woman, believed to be in her 80s, was the subject of a nationwide police appeal as she was unable to tell doctors at Nambour Hospital who she was, due to a 'challenging health situation'. 

It has now been revealed that the woman will stay in the care of Queensland Health after she managed to communicate to doctors that she was aware of who she was but did not want to share her identity with the authorities.  

Cops have dropped the case after a month-long search for the woman's relatives. 

'The woman recently began speaking with police and has clearly indicated she is aware of her identity,' Queensland Police said in a statement on Sunday. 

A mystery elderly woman , believed to be in her 80s, who was picked up on the side of the road and taken to hospital has refused to reveal her identity to police 

Police said the woman faced a 'challenging health situation' when she arrived at hospital and struggled to identify her as she was non-verbal and needed medical care  

Police said she did not wish to share her identity with them 'for personal reasons'.  

The woman was initially 'challenging' to identify because she was non-verbal and in need of medical attention when she arrived at hospital.  

Police said public assistance was now no longer required and asked that 'the public and the media respect the woman’s privacy as per her request.'

'As no criminality has been detected, police have ceased involvement in this matter and the woman will be left in the care of Queensland Health,' the statement said.    

Investigators issued a number of alerts in a bid to reunite the woman with her family after she was found, saying the situation was unique and almost like a reverse missing person's case.

She started talking with people after she was transferred to Sunshine Coast University Hospital and her health improved.   

Police released an image of the woman's ring in the hopes it might help someone identity her

Police Inspector Matt Robertson says the woman had been in a vulnerable situation and 'very frail', requiring medical treatment. 

The man who found the woman took her to hospital and told staff he didn't know her and had no reason to think he was doing anything except helping her.  

'He came in, he stated exactly what occurred and at this stage the evidence suggests what he said occurred,' Inspector Robertson said, according to the ABC.

'He does believe he might have seen her in the area before.'  

They do think there may be a story to tell however and the missing piece was a 'puzzle'. 

Police also released an image of the woman's ring in the hopes it would help someone identity her. 

'Our primary investigation is just to locate who this lady is to reunite her with her family,' Inspector Robertson said. 

'It's not something where we've been able to go charging in very quickly with and we're taking it one step at a time and exploring those avenues as she's capable.' 

The woman, believed to be in her 80s, was picked up by a driver on Brandenburg Road in Mooloolah Valley on September 6 and dropped outside Nambour Hospital
