Carl Panzram — a tattooed, 6-foot-tall giant of a man with cold gray eyes — stowed away on a ship bound for Angola around 1920 to work as a merchant seaman. After arriving in Lobito Bay, he hired a half-dozen local guides for a crocodile-hunting expedition. But Panzram had other prey on his mind. As their canoe wended its way down the river, he shot each crew member dead before feeding their corpses to the hungry crocodiles lurking below.
That was just one of many crimes, including 21 murders and more than 1,000 rapes of young boys and men, Panzram admitted to committing. Unlike charming and cunning serial killers Ted Bundy or Rodney Alcala, Panzram remained brutally honest. “For all of these things, I am not the least bit sorry,” he seethed in his autobiography, penned from his prison cell. “I hate the whole damned human race including myself.”
