Do you know how far the tunnel in the wall goes? I know someone suggested this earlier, but maybe try alerting your neighbors and asking if they've heard any scrabbling in the walls. Hope she comes out soon, try checking in any and all openings around your house. Anywhere you know or think there's a hole, leave some of her bedding right outside it with food. Good luck, don't lose hope yet! I've heard stories of hams disappearing for months only to one day return back to their cages, in fact, I've heard a story where a fire ravaged a house and the family later found their hamster that had been missing for over a month and she was only minimally impacted by the smoke. Be as vigilant as possible
