In November, 1873, 21 men headed for the gold field in Breckenridge, Colorado. Their guide, Alferd Packer, ended up being terrible with directions. The weather was awful and the men ran out of provisions pretty fast. They began splitting the group up and Alferd was in charge of guiding 5 men through the mountains. Unfortunately, Alferd was the only one of his group to make it out alive. He told many stories about his journey and people began noticing the inconsistencies. Alferd finally admitted that the other men had been killed and even though his story kept changing, there was cannibalism involved.
