Fioravanti was doing military service when the first killing occurred , it is believed to have been committed by either Cristiano or Alibrandi in September 1977 ; a leftist militant was shot dead . The victims of Armed Revolutionary Nuclei that followed included several policemen ( this was justified on the grounds of them being ' thugs and torturers ' ) , comrades suspected of treachery , and investigating magistrates including Mario Amato . Fioravanti was 23 , and Mambro 21 , when warrants charged them with the Bologna massacre bombing of 2 August 1980 , which killed 85 people . Both Fioravanti and Mambro were convicted of the Bologna massacre
