Occam's Razor

The body was positioned so that the train would neatly obliterate its head and hands. Dressed in a homeless man's clothes with empty pockets, it might easily be passed off as an unfortunate John Doe. But Joe Gunther has a knack for knowing when things don't quite add up, and the math in this case is all kinds of wrong. A toxic waste dumping scheme, a stabbing, and a whole lot of state politics quickly complicate matters further. If Occam's razor were applied to Gunther's caseload, how many incisions would it make?
