stolen 2016 Other Women's mixte

This happened in the locked bike cage of my apartment at any time in between Saturday 9/17 and today at 4pm 9/27. When I went to look at it today, the bike cage was propped open for some reason so it might have been really easy for someone who didn't live there to get to the bikes inside. Mine was completely gone but there were 4 or so tires with locks still attached left, so a lot have been stolen from the same area. The bike cage is locked but it's in a parking garage that isn't so if it was left open, all the bikes were available to anyone.
