...and that's the last time we'll hear from EvBitcoinFan

Im not so sure about that. If OP has his real identity, he could charge him for internet fraud (or however you call it in the US), here where i live you can get even upto 2yrs jailtime for that.
Why exactly were you willing to send him so much money without using escrow? Everyone else he dealt with involved escrow being used.
Even if someone trades honestly for a few short months, chances are that if you sent them a large amount at once without escrow that they are going to end up running away with your money
He did it because he trusted all the positive feedback that user had to that point. I often find myself also sending first to such persons, without escrow, but not in such large amounts, mostly <1

@op i would contact him, and later on his family with a few phone calls, explaining what happened. Maybe they are more interested in sorting this out than him. Really hope you get your money back.
