In the winter of 1874, Alfred Packer led a group of prospectors into the San Juan Mountains of Colorado. After returning alone, he confessed to eating the remains of his travel companions, and was convicted of murder despite claiming self-defense. The conviction sealed his place in history as the "Colorado Cannibal." After almost 150 years, Noel and Tyler look back at Packer's story and discover there's much more to it than simple questions of guilt or innocence.
