Calgary police need the public’s help in finding a woman who hasn’t been seen since October.

Lisa Mitchell, 29, was last seen in Longview leaving for Calgary on October 29, 2011.

Police say she may have been seen near her home in the community of Ogden, but her family has not seen or heard from her and has declared her missing.

The investigation has led police to believe she may have travelled to the Edmonton or the Fort McMurray area.

At this point police have no reason to suspect foul play but say she suffers from a medical condition that could worsen if not treated.

She wears glasses and has a tattoo of a large phoenix on her upper, left arm.
