Jack Unterweger — The Journalist Killer

Jack Unterweger was an Austrian serial killer who murdered a young woman in 1974 and was sentenced to life imprisonment, but was released in 1990 after becoming a celebrated author and prison reformist championed by the Vienna intelligentsia. Within months of his release he began murdering sex workers in Austria, Czechoslovakia, and the United States, killing at least 11 women. He was convicted of nine murders in 1994 after investigators across three countries linked victims by the identical knots used to bind them. Unterweger hanged himself in his cell on the night of his conviction.
