ernest is right, thieves are pretty much stupid! maybe they mite sell it out of that area? if i was you, i would check the serial number on every one you see, if possible! if they arent stupid and keep it in that same area, they mite try to make it look different than it does now, like put an older cover on it or dog out the paint to make it look older? who knows? good luck!!
Did you make a police report and provide the serial number and any unusual markings on it? They do recover a few. I wish you luck .
