A Chestermere woman has been missing for nine days, and Calgary police are asking anyone who may have seen her at a Forest Lawn supermarket to come forward.
Thi, 30, was last seen at Lucky Supermarket, at 4527 8 Avenue S.E., on Monday, Sept. 28. Her family dropped her off there at about 8:45 a.m.
She hasn't been seen since.
"It is unusual for Thi to be out of contact with her family for this long," Calgary police said when they asked for the public's help on Oct. 6.
Police say there's nothing to suggest foul play, but her family and police are concerned for her well-being.

Were you at Lucky Supermarket that morning?
Police know where Thi was at about 8:45 a.m. on Sept. 28. They haven't said what she planned to do after she was dropped off, or where she went next.
Thi lives in Chestermere, just east of Calgary, but her last known location was in southeast Calgary.
If you were shopping at Lucky Supermarket, working nearby, or passing through that part of Forest Lawn that Monday morning, think back. If you remember seeing a woman matching her description, or know where she went next, call police, even if you're not sure it matters.
