(Newser) – The thing about elevator doors is that they open and close, a point to keep in mind if you're planning to rob someone in an elevator. Deputies in Florida's Broward County say surveillance video shows a man armed with a knife entering an elevator and taking the purse of a 77-year-old woman, reports CBS12. Then he tries to leave and walks smack into the closing doors. He eventually gets out and is still at large, but now that his image is circulating nationwide as the object of ridicule, that might not last long.
