Charles "Carl" Panzram was an American serial killer, rapist, arsonist, robber and burglar. In prison confessions and in his autobiography, Panzram claimed to have committed 21 murders and more than 1,000 acts of sodomy of boys and men.
One of Panzram’s most brutal murders involved hiring six men to work on a boat with him, shooting them, and then feeding them to crocodiles. In his autobiography, he wrote, “For all of these things, I am not the least bit sorry.”
