call the local police in his area and register a complaint. maybe tell him you are pressing charges first and see what he says.
it went beyond a civil matter with his antics and he turned it into a felony.
This is common little bit of misinformation. Unless you actually go to Chicago or retain a lawyer there to do it for you it's pretty unlikely that you could even get a cop to take a complaint and write the Rico a ticket. If they did agree to seek out the Rico for your accusation of a $500 theft and write him a ticket the city attorney would need to pursue this as a criminal matter, so any charges would have to be "pressed" or filed by a city attorney who would likely tell you that this is a small claims court matter. I would think that in this particular situation, if you were going to take the legal route you have better luck and a little more leverage going after the person that actually picked up the cue at your door. or.....
