Life imprisonment for the Casalesi boss Francesco Schiavone alias 'Sandokan' and Giovanni Diana for the murder of the traffic policeman Antonio Diana. The agent was killed in 1989 in San Cipriano d'Aversa . This was decided by the Court of Cassation which confirmed the verdict issued in 2019 by the Court of Appeal of Naples , putting an end to a proceeding in which the protagonists were the collaborators of justice, including the former fugitive boss Antonio Iovine, Carmine Schiavone, Giuseppe Quadrano, whose declarations have allowed the District Anti-Mafia Directorate of Naples to reconstruct after almost 30 years the roles of the various members of the clan in the planning and execution of the crime.
In total there were 9 defendants, but seven, including Iovine himself, chose the shortened procedure (all already convicted) while Sandokan and Diana went to the trial. From the trial it emerged that Francesco Schiavone was the instigator while Diana the mirror maker who had the task of locating the victim and also keeping the weapons.
The traffic policeman Antonio Diana was killed in the feud that at the end of the 1980s contrasted the groups led by Francesco Schiavone and Francesco Bidognetti with that of the founder of the clan Antonio Bardellino. In particular, the murder of Diana was a response to the murder of Michele Russo, near Sandokan and killed by the Bardellino killers. Francesco Schiavone believed that the traffic policeman had acted as a mirror during the Russo's crime, and so he gave the order of death.
