Calgary police have renewed their plea for the public's help as the two-year anniversary of Lisa Michelle Mitchell's disappearance approaches.

The 31-year-old Calgary woman was last seen leaving the home she shared with her common-law partnerin Ogden, heading to a convenience storeon Oct. 29, 2012.

The day before, Mitchell had been with her family in the Longview area.

Police want to hear from anyone who has information on her movements around that time. Sgt.John Hebert,with the missing persons team, saidthere are no indicationsMitchell led ahigh-risk lifestyle but they still don't know if she met with violence.

"It's something that we haven't eliminated and we're open to all possibilities, but we just haven't been able to have any conclusive evidence that would lead us down that path," said Hebert.

Mitchell's family reported her missing and a call-out for the public's help was initially made in January 2013.

Investigators are concerned that Mitchell suffers from a medical condition and may not be getting the treatment she needs.

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