Funny you say that since it turned out from surveillance footage from another building that the burglars where dressed as movers and loaded all the items into a small moving van that was double parked.
Forget about stealing safes from apartments, I wouldn't be shocked if you could rob an actual bank vault by dressing as a construction crew.
University I went to had this happen in the summer. Showed up in coveralls and had a paper for the RA to sign. Cleared out all the furniture and appliances. Told the RA that the new stuff was a bit late but would be there in an hour. They were not caught but I question the target’s value.
