SHE left work and after going home to get changed she was supposed to be meeting friends for a drink later that night.
But after saying goodbye to her husband and her sister, who said she seemed disorientated at the time, Maryellen McMillin never arrived.
And although she was legally declared dead in 2004, a friend of the family revealed that until they get full proof the doubts will always linger.
They said: "There's always that lingering doubt, until something or someone comes up, you always wonder what may have happened."
When the physician's assistant described as "hardworking and conscientious" at the Carlson Center in Fairbanks, AK, didn't show up for work and the hunt was on, after she was supposed to be meeting her pals.But despite a huge search, neither the 37-year-old or her dark green Subaru Loyale, with Alaska License number CSY-207 was ever seen again.
At first it was feared that she may have driven into a ditch, but searches turned up nothing.
There have also been a few possible sightings, once in Anchorage and at one point authorities thought she might be working in Wasilla.
There was also a suspicious phone call to her work in April 1999 asking if she was still alive, but with little to go on, cops can't act.
