Carl Panzram is sent to Leavenworth Prison for burglary. While there, he is brutally beaten by a guard. Neophyte guard Henry Lesser feels sympathy for Panzram, befriends him, and gets him to write his life story. Lesser learns that Panzram's past is much more violent than he thought, but also that he's capable of being a much better person than the rest of the prison staff believes - or so Lesser thinks.
Killer: A Journal of Murder (1995) is an American drama film written and directed by Tim Metcalfe. It is loosely adapted from a book of the same title, on the life of American serial killer Carl Panzram, who was active in the early 20th century and executed in 1930. It uses some passages drawn from his own writings near the end of his life.
