Bicycle detail

I left my bike in my apartment's "secure", locked bike room (it's only accessible by residents with a FOB key) and it was also locked to the hanging rack it was on. I locked it up at 8:30am Tuesday August 16th after I got home and when I went down this morning (6:30am Thursday August 18th) it was gone. I had locked it to my husband's bike which was on the rack next to mine so they were locked together. My bike, the lock, and both our helmets were stolen. His bike was left. There were other bikes in the room that weren't locked up yet mine was still stolen even though it was locked.
