stolen 2012 Cannondale Synapse

My bike was stolen from my porch in the middle of the night, it is almost brand new and was a hefty investment, the most expensive thing i own and my only mode of transportation. Whoever stole it also left their own crappy bike in my yard along with some articles of clothing. They also broke into a neighbor's car the same night. I am really torn up about this and presume they may try and sell it with no paper trail. I don't know but i am trying everything to retrieve it. :(
