stolen Specialized Hotrock 20 Boys

I bought this bike from a Craigslist person. The seller was not friendly, and he did not give me his name. Moreover, there were 150-200 bikes in his back yard, stacked in rows and covered over with tarps. I froze. I failed to ask the proper questions and bought the bike despite my screaming instincts. If the bike's proper owner can be found, I want to get this bike back to them, and see if the other 200 bikes can be recovered as well.
