Before driving the guy crazy or doing other things you may later regret...it has only been a couple weeks, right?
Do you know if the guy is a known scammer to other enthusiasts? .
Maybe he's really just a good guy who's out of town or wrapped up in a personal or family situation? .
I'd consider checking deeper into who you're really dealing with and try futher attempts at contact before the conviction and sentencing stuff? .
