Italicus train massacre: 51 years later, no convictions.

It is 1:23 a.m. on the night of Sunday, August 4, 1974. Near San Benedetto Val di Sambro, in the Bologna Apennines, a high-explosive bomb explodes in carriage number 5 of the Italicus train 1486, departing from Rome and bound for Munich. The attack kills 12 people and injures 48. Among the victims is Forlì railway worker Silver Sirotti, a gold medalist for civil valor, who was not even supposed to be on duty that night. He was among the first to assist passengers in the stricken carriage and died overcome by fire and smoke. The legal proceedings have not led to the explicit conviction of those responsible, but the Italicus massacre, too often forgotten, is part of the bloody chain of far-right Italian mass killings—as underscored by the ruling of the Court of Cassation and the conclusions of the Parliamentary Commission of Inquiry into the P2 lodge.
