In 1978, Peppino Impastato stood as a candidate in the Cinisi council elections for
Proletarian Democracy (Democrazia proletaria). He was killed during the election campaign on the night of May 8–9, by a charge of TNT placed under his body, which had been stretched over the local railway line
[1] – a sinister twist of fate to the car-bomb that had killed his uncle and initiated Peppino's revolt against the Mafia. The same day, Christian-Democrat Prime Minister
Aldo Moro's corpse was discovered on via
Caetani in Rome. Two days later voters in Cinisi elected him as a councillor.
