Yesterday, we reported on a brutal hate crime that took place in Philadelphia. The beating by a “well-dressed” mob left two men in their late twenties with their jaws wired shut.

The story was covered by many news outlets and went viral on Twitter fairly quickly. By the end of the evening, however, a Philadelphia-area sports fan had managed to identify most of the suspects in the video footage, and passed the information on to the police. Three cheers for Philly-sports-Twitter! Here’s how it went down. (By the way, the police have thanked this user already and several suspects have already lawyered up. Learn more on Gawker.)
