After Italy's liberation from the German occupation, Caruso was tried for his numerous crimes, sentenced to death on 21 September 1944 and executed by a firing squad of Polizia di Stato in the courtyard of the Fort Bravetta in Rome. The high court of justice also condemned Roberto Occhietto, Caruso’s secretary and co-defendant, to 30 years’ imprisonment on the same collaboration charge. The eight-man high court, presided over by judge Lorenzo Maroni, heard prosecutor Mario Berlinguer characterize the two defendants as “wild beasts” and the verdicts were delivered after two hours’ deliberation.
