Stolen Bike! Please Help me find it-- it's my only transportation!

Lock up your bikes with a U-Lock! I learned the hard way and I couldn't be more sad.

I live near the streets of 18th and Spruce and my dear K2 Attack Mountain bike was stolen on January 14th in the middle of the night. I have a pretty hefty lock (steel cable with rubberized outside). I locked my bike to my porch (RIGHT NEAR MY WINDOW AND NOT EASILY ACCESSIBLE FROM THE STREET). The next day it was gone and the lock was sawed off and laying there.

I'm extremely distraught and desperately need my transportation back!If anyone has any information about the incident I would be superbly appreciative!
Many thanks for your help!
