Joseph Quartieri is a man who investigators believe is connected to the infamous Gambino crime family. Back in 1979, cops say, Quartieri botched a jewelry store robbery on New York's Long Island, nearly killing a police officer in the process. He was arrested, but broke out of jail before his trial and vanished. Now police wonder if a mysterious man they spotted attending recent mob funerals might be the long-lost fugitive.

For AMW's Jon Leiberman, this case was his first real exposure to the world of organized crime. Jon sat down with investigators for a briefing on the ins and outs of the mob, and after chatting with police, the possible sightings of Quartieri become even more interesting. "I learned that cops usually know who everyone is at mob funerals," Jon says. "The fact that they caught a guy on tape who they can't ID is bizarre." After 30 years of dead-end leads, this may finally be the break police have been waiting for.
