NEARLY three months on, police are still working to unlock the mystery of what happened to Tina Greer.
With the last confirmed sighting of the 32-year-old mother on January 18, those in charge of the investigation admit the prospects of finding her alive grow dimmer each day.
But Ipswich Acting Detective Gary Dixon said police still hoped to find Ms Greer alive.
Police used cadaver dogs, horses and helicopters to search bushland between Spicer's Peak and Moogerah Dam.
They are still unable to explain how Ms Greer's maroon Commodore ended up at the car park near Governor's Chair lookout, off Spicer's Gap Rd. It was found locked on January 22.
Ms Greer lived at Beechmont but was known to have a boyfriend with a property in the Fassifern area. Police searched the property and questioned the man, who is a member of the Finks motorcycle club.
Phone Crime Stoppers on 1800 333 000.
