Carlo Digilio

Carlo Digilio, also known as Zio Otto (7 May 1937 – 12 December 2005), was an Italian terrorist, soldier, and self-styled secret agent. He belonged to the neo-fascist group Ordine Nuovo and later became a collaborator. At the end of the first-degree process, he was convicted for the Piazza Fontana bombing, but the reliefs of law extinguished his guilt. He was also involved in the Piazza della Loggia bombing.

In fall 1992, he was arrested under an international warrant and returned to Italy, where he was sentenced to 10 years. Digilio became the first collaborator of so-called black extremism. He testified to have worked with Franco Freda, Delfo Zorzi (who was absolved), and Carlo Maria Maggi (a member of the Venetian section). In 1994, Digilio and Martino Siciliano asserted that Delfo Zorzi -and not the anarchist Pietro Valpreda- had been the material executor who had placed a bomb in front of the Banca Nazionale dell'Agricoltura, in Milan. They also declared that, in doing so, Zorzi had been helped by the son of a banking director. Subsequently, Valpreda was processed and absolved of these charges. In 1995, his deposition against Zorzi was declared to be unreliable due to a stroke that had caused memory loss.

Thanks to the reliefs of law, Digilio's actions around the Piazza Fontana bombing were not chargeable, and his lawyers didn't appeal. The judges also ascertained his involvement in the Piazza Della Loggia bombing.

Digilio spent his last years within the protection program under the name of Mario Rossi. He died in a rest home in Bergamo on 12 December 2005, the 36th anniversary of the Piazza Fontana massacre.
