In April 2002, an Italian court convicted him of the 1978 murder of activist radio broadcaster Peppino Impastato and sentenced him to life imprisonment. Impastato used humor and satire as his weapon against the Mafia. In his popular daily radio programme "Onda pazza" (Crazy Wave) he mocked politicians and mafiosi alike. On a daily basis he exposed the crimes and dealings of mafiosi in "Mafiopoli" (Cinisi) and the activities of "Tano Seduto" (Sitting Tano), a thinly disguised pseudonym of Don Tano Badalamenti, the capomafia of Cinisi.
