Germany has extradited back to Sweden a convicted killer known as “the laser man” for using a precision-scope rifle to target immigrants.

John Ausonius, 65, a Swedish far-right extremist, has been found guilty of murder in both countries, most recently receiving a life term in Germany in February last year that was upheld on appeal in November.

He previously received a life sentence in Sweden for a six-month shooting spree in 1991-92. Using the laser-scoped rifle, he killed a 34-year-old Iranian man and wounded 10 other people from countries including Brazil, Greece, Syria and Zimbabwe.

In a sign of Ausonius’s notoriety, the Norwegian white supremacist mass murderer Anders Behring Breivik mentioned the “laser man” as a figure who shared the same goals during his own trial.

Ausonius was extradited to Germany in late 2016, and in February 2018 he was found guilty of the 1992 murder of a 68-year-old Jewish Holocaust survivor, Blanka Zmigrod, in Frankfurt.

Having now received life terms in two countries, Ausonius is considered almost certain to spend the rest of his life locked up without parole.
