stolen 2009 Trek Alpha 1.1

I parked my bike around Canal and Church by the post office. it was stolen while I was getting a pizza. It was a 54cm Trek Road Bike with a back rack and blue milk crate. I thought I attached it to the main scaffolding but it looks like the smaller bar was removed indicating that i attached it to that. they cut through the kyroptyite tire chain and left my helmet.
