The confessed Colorado cannibal Alfred Packer is released from prison on parole after serving 18 years.

One of the ragged legions of gold and silver prospectors who combed the Rocky Mountains searching for fortune in the 1860s, Alfred Packer also supplemented his meager income from mining by serving as a guide in the Utah and Colorado wilderness. In early November 1873, Packer left Bingham Canyon, Utah, to lead a party of 21 men bound for the gold fields near Breckenridge, Colorado. The winter of 1873-74 was unusually harsh. After three months of difficult travel, the party staggered into the camp of the Ute Indian Chief Ouray, near present-day Montrose, Colorado. The Utes graciously provided the hungry and exhausted men with food and shelter. Chief Ouray advised the men to stay in the camp until a break came in the severe winter weather, but with their strength rekindled by food and rest, Packer and five other men decided to continue the journey.

Two months later, Packer arrived alone at the Los Piños Indian Agency, looking surprisingly fit for a man who had just completed an arduous winter trek through the Rockies. Packer first claimed he had become separated from his five companions during a blizzard and survived on rabbits and rosebuds. Suspicions grew, though, when it was discovered that Packer had an unusual amount of money and many items belonging to the missing men. Under questioning, Packer confessed that the real story was far more gruesome: Four of the men, he claimed, had died naturally from the extreme winter conditions and the starving survivors ate them. When only Packer and one other man, Shannon Bell, remained alive, Bell went insane and threatened to kill Packer. Packer said he shot Bell in self-defense and eventually ate his corpse.

Though shocking, Packer’s grisly story would probably have been accepted as an unfortunate tragedy had not searchers later found the remains of the five men at a single campsite—not strung out along the trail as Packer had claimed. Packer was arrested and charged with murder, but he escaped from jail and remained at large for nine years.

Recaptured in 1883 near Fort Fetterman, Wyoming, Packer once again changed his story. He claimed that all six men had made camp alive, but lost and starving, they were too weak to go on. One day Packer went in search of the trail. Upon returning several hours later, he discovered to his horror that Bell had gone mad, killed the other four with a hatchet, and was boiling the flesh of one of them for his meal. When Bell spotted Packer, he charged with his hatchet raised, and Packer shot him twice in the belly. Lost and trapped alone in a camp of dead men, Packer said he only resorted to cannibalism after several more days, when it was his only means of survival.

Having twice changed his story, Packer undermined his own credibility, and a jury convicted him of manslaughter. He remained imprisoned in the Canon City penitentiary until 1901 when the Denver Post published a series of articles and editorials questioning his guilt. Eventually, the state freed Packer on parole. Packer went to work as a guard for the Post and lived quietly in and around Littleton, Colorado, maintaining his innocence until the day he died in 1907.

Though we will never know exactly what happened on the so-called “Cannibal Plateau” near present-day Lake City, Colorado, recent forensic studies of the remains of the men who died have tended to support the details of Packer’s second confession.
