Thanks for all the info! I will be rooting the phone tonight and hopefully retrieving the picture. Once I get the picture I plan on pulling the metadata out of the picture. With any luck, there will be a time, date, and GPS coordinates embedded in it.
I know it's the guy because I was trying to help this punk with his newspaper subscription. Yes, insert the "I'm an idiot" comments HERE. He walked out with my phone so I know exactly what he looks like.
Yes, might be difficult to prove he stole it, and I don't expect charges to be pressed and him to be captured, but in the meantime, scaring the absolute crap out of him (and everyone he called - yes, I pulled my call logs and I plan on calling each person on the list) is almost as satisfactory as catching him.
