Jack Unterweger was an evil man whose lust for violence was insatiable. His first known murder victim was Margret Schafer, an 18-year-old German girl. Unterweger would tell a jury that, at the moment of her killing, he had seen his mother reflected in her face and he acted out of a lifetime of rage. He was sentenced to life imprisonment. But in jail, Unterweger read voraciously and he began to write poetry, short stories, plays, and an autobiography.
