John Wolfgang Alexander Ausonius (born Wolfgang Alexander Zaugg, 12 July 1953), known in the media as Lasermannen ("the Laser Man"), is a Swedish convicted murderer, bank robber, and attempted serial killer.
From 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.
Additionally, in February 2018 he was sentenced to life imprisonment in Germany for the 1992 murder of Blanka Zmigrod.
