 Huber was assassinated shortly before he was due to testify before Magistrate Hernán Correa de la Cerda in a case concerning the illegal export of weapons to the Croatian army.That enterprise involved 370 tons of weapons sold to the Croatian government by Chile on 7 December 1991, when Croatia was under a United Nations embargo arising from the war in Yugoslavia.In January 1992, Magistrate Correa sought testimony from Huber on the deal.
