Franz Fuchs

Franz Fuchs (12 December 1949 – 26 February 2000) was an Austrian domestic terrorist who killed four people and injured 15, some seriously, using three improvised explosive devices and 24 mail bombs, which he sent in five waves between 1993 and 1997.

Criminal psychologists characterized Fuchs as a highly intelligent but socially inept loner. He targeted people he considered to be foreigners, or organizations and individuals who he believed were "friendly to foreigners".

According to a study, Franz Fuchs inspired Pekka Eric-Auvinen to kill 8 of his classmates during the Jokela school shooting in Finland in 2007. Provided by Wikipedia
