A teenager shopping at a New York boutique clothing store ended up trapped inside a dressing room that used to be a bank vault. Giavanna Diesso, 14, was trying on clothes when her little brother, Vincent, decided to pull a prank and close the door. The store owner said the lock on the vault-turned-dressing room had been disabled, but because it was 100 years old, it somehow malfunctioned and locked her inside. Firefighters used hammer drills and chisels to cut through the 1-foot thick vault wall. #InsideEdition
