When a haggard Alfred Packer stumbled from the Colorado wilderness in 1874, he at first said he'd been abandoned by five traveling companions who'd left him to fend for himself. But his already-shaky story quickly changed once a search party uncovered the remains of five mutilated men. Packer -- sometimes referred to by the first name "Alferd" thanks to a misspelled tattoo -- went down in history as the so-called Colorado Cannibal, but debate lingers to this day over whether he'd committed premeditated murder or simply found a way to survive horrifying circumstances.
