stolen Giant Escape 2

Bike was locked but the lock was running through the front tire instead of the bike itself. Bike frame and back tire stolen while front tire removed and still locked to bike rack. We don’t have a serial #. It had been serviced before by our local bike shop, will find out if they recorded the serial #. The chain was a bit rusty from being outside. Not sure if the model is a 2 or 3. I found the serial #, from when bike was last serviced it’s C12C2748.
