Carl Panzram

Charles "Carl" Panzram (June 28, 1892 – September 5, 1930) was an American rapist, serial killer, and habitual offender. In prison confessions and in his autobiography, Panzram confessed to having murdered twenty-one boys and men, only five of which could be corroborated. He is suspected of having killed more than a hundred boys and men in the United States alone, and several more in Portuguese Angola.

Panzram also confessed to having committed more than a thousand acts of rape against males of all ages. After a lifetime of crime, during which he served many prison terms and escaped from many prisons, Panzram was executed by hanging in 1930 for the murder of a prison employee at the United States Penitentiary in Leavenworth, Kansas.
