Vincenzo Vinciguerra (born 1949) is an Italian neo-fascist activist, a former member of the Avanguardia Nazionale ("National Vanguard") and Ordine Nuovo ("New Order"). He is currently serving a life-sentence for the murder of three Carabinieri by a car bomb in Peteano in 1972. The investigation in this previously unsolved affair by prosecutor Felice Casson led to the revelation of "Gladio" networks around Western Europe.
Following juridical investigations, it has been discovered that the C4 explosive (the most powerful explosive available at the time) used in the 1972 bombing came from a Gladio arms dump located beneath a cemetery near Verona, whose existence was revealed to judges Felice Casson and Carlo Mastelloni by Giulio Andreotti, former Prime minister of Italy. Judge Casson's investigations revealed that Marco Morin, an explosives expert who worked for the Italian police and a member of Ordine Nuovo far-right group, had deliberately provided a fake expertise, claiming that the explosives used were the same that the Red Brigades used. However, Casson demonstrated that the explosives were in fact C4, which was used by NATO. A group of Carabinieri had accidentally discovered on February 24, 1972, an arms dump near Trieste, containing arms, munitions and C4 identical to the one used in Peteano the same year. According to historian Daniele Ganser:
Casson's investigation revealed that the right-wing organization Ordine Nuovo had collaborated very closely with the Italian Military Secret Service, SID (Servizio Informazioni Difesa). Together, they had engineered the Peteano terror and then wrongly blamed the militant extreme Italian left, the Red Brigades. Judge Casson identified Ordine Nuovo member Vincenzo Vinciguerra as the man who had planted the Peteano bomb... He confessed and testified that he had been covered by an entire network of sympathizers in Italy and abroad who had ensured that after the attack he could escape. 'A whole mechanism came into action', Vinciguerra recalled, 'that is, the Carabinieri, the Minister of the Interior, the customs services and the military and civilian intelligence services accepted the ideological reasoning behind the attack.'
