About Carl Panzram
Charles "Carl" Panzram 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. By his early teens Panzram exhibited alcoholism and had a lengthy criminal record, mostly for burglary and robbery offenses. This event marked Panzram's first known involvement in a murder, as an accessory before the fact. In his prison record, which noted his two aliases, "Jefferson Davis" and "Jeff Rhodes", Panzram falsely gave his age as 30, and his place of birth as Alabama.
