Sebastiano Nirta was sentenced to life in prison on a definitive basis for the charge of six murders and possession and ports of common firearms in competition in the context of the Duisburg massacre, which marked, as claimed by the investigators, the apex of the San Luca feud between the opposing factions of Nirta-Strangio and Pelle-Vottari.

The second criminal section of the Court of Cassation rejected the appeal presented by the defenders of Sebastiano Nirta (cl. 1971).
