Ver en Cuevana. The true story of lifelong criminal and serial killer, Carl Panzram who wrote his autobiography for a jail guard in 1928. Carl Panzram was a lifelong prisoner and a hate-filled serial killer. Brutalized in and out of various U.S. state prisons during 20th century America, Panzram unleashed a rampage of revenge that resulted in over 20 murders and countless acts of violent sodomy. A single act of kindness, by prison guard Henry Lesser, sparked a friendship that eventually influenced Panzram to write his autobiography. In 1930, Panzram was hanged for killing a laundry foreman at Leavenworth prison.
