Three years after Stephanie Stewart disappeared from a Hinton-area watchtower, investigators are no closer to knowing why.

“So far, we’ve followed up on everything we have and we’re looking for more,” said Sgt. Patrick Webb. “Our last tip was a couple of months ago.”

Stewart went missing from the Athabasca Lookout Tower where she worked on Aug. 26, 2006.

Like any lone fire-spotter, she was required to phone to base three times each day to file reports.

When she didn’t respond to a call on Aug. 26, a supervisor went to the site to check on her.

Not only was Stewart nowhere to be found, but several items were missing from her house.

After an extensive search-and-rescue effort involving hundreds of volunteers, police ruled out the possibility that Stewart was simply lost or that she had been the victim of animal attack.

Police are continuing the investigation, actively seeking public assistance with any information that could prove helpful.

The police currently have no leads to pursue, Webb said, adding they hold out hope for answers.
