I'm also curious about this. One option would be to lure the troll to a site & pull down the location info from his browser - I'm not sure how readily the troll would authorize that, but maybe with some clever social engineering it could be done. His father did mention he was on his mobile a ton, so it's possible he got pretty accurate data, instead of just his local ISP. (Related - I'm on Clear right now, and apparently I'm in Portland. I'm actually up near Canada.)
