The woman, believed to be in her 80s, was picked up by a driver in Mooloolah Valley on Sept. 6 and dropped outside Nambour Hospital.
Her identity remained a mystery for weeks, with police initially unable to ask the woman who she was because she was suffering a “challenging health situation.”
Police said on Sunday the woman recently began talking and declined to disclose her identity for personal reasons.
“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,” a police spokesperson 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.
