His name is Agent Moriarty. It's like a Sherlock Holmes crossover. Remember in one of the season finales the guy who said "Red John is a friend of a friend of mine." The one Jane had to break out of jail that got away in the end and fled to Mexico only to wind up dead with a hooker in the bathtub. He wrote on the wall "He is MOR–" MOR are the first three letters for Moriarty.
