Good luck! My brother had his bike stolen when he was in high school.. I was telling my best friend about how it'd been taken the night before, and she told me "Hmm, that's strange, my older brother came home with a bike last night."
So we went over there.. sure enough, my best friend's older brother had stolen MY older brother's bike! xD
Seriously, though, I hope you catch him. That is so messed up. =\\
