By 40 years of age Jack Unterweger was a man of many talents and skills. He was an actor, an author, a batterer, a burglar, a car thief, a celebrity convict, a children’s storybook teller, a crime scene analyst, a director, a fraudster, a humorist, a journalist, a lawyer, a liar, a ligaturist, a malignant narcissist, a novelist, a pimp, a playwright, a poet, a rehabilitated poster-boy, a reporter, a robber, a screenwriter, a serial sexual killer, a signaturist, a thief, a torturer, and a womanizer. As a way of telling you more about the “real” and “fantasy” life of Jack Unterweger, let me provide a brief overview and theoretical context of the two key criminological-psychological concepts that are relevant to The Infernal Comedy: Confessions of a Serial Killer. First, I need to address a subset of serial murder. I am referring to serial murder that is sexual in nature. Second, I need to address a subset of narcissistic personality disorder called malignant narcissism.
