Carl Panzram was an American serial killer, rapist, arsonist, and burglar. In prison confessions and his autobiography, he claimed to have committed 21 murders, most of which could not be corroborated, and over 1,000 sodomies of boys and men. After a series of imprisonments and escapes, he was executed in 1930 for the murder of a prison employee at Leavenworth Federal Penitentiary.
Panzram was hanged on September 5, 1930. As guards attempted to place a black hood over his head, he allegedly spat in the executioner's face. When asked for any last words, he responded, "Yes, hurry it up, you Hoosier bastard! I could kill a dozen men while you're screwing around!" His grave, at the Leavenworth Penitentiary Cemetery, is marked only with his prison number, 31614.
