John Wolfgang Alexander Ausonius (born Wolfgang Alexander Zaugg, 12 July 1953), known in the media as Lasermannen ("the Laser Man"), is a Swedish far-right extremist convicted of serial murder and 10 bank robberies. Between August 1991 to January 1992, he shot eleven people in the Stockholm and Uppsala area, most of whom were immigrants, killing one and seriously injuring the others. He first used a rifle equipped with a laser sight (hence his nickname), and later switched to a revolver. He was arrested in June 1992 and sentenced to life imprisonment in January 1994.
