Building a secret apartment in the mall

Eight artists built themselves a one room studio in the mall parking garage and kept it a secret for FOUR YEARS!  It's one of those interesting crimes that makes you wonder how you could do it and not get caught.  (Unless you are homeless or want to make a statement, there's probably no real reason to create a one room studio in a parking garage.) You can read more about it in the Rhode Island news: 1 room, no view.
