Giovanni Falcone had planned to create a "bank of voices" already known by the affiliates of Cosa Nostra, to be used on occasion to compare them with anonymous talkers who were intercepted from time to time.
29 years after the Capaci massacre, in which the mafia killed the magistrate, his wife Francesca Morvillo and the men of the escort, reveals Professor Ugo Cesari, otolaryngologist and phoniatrist, professor at the Federico II University of Naples, consultant to the judge.
Those reports, accompanied by spectrographic tracings, were little used in the Eighties: "Only later - observes Cesari - did the prosecutors of Naples also understand their usefulness for telephone and environmental wiretapping and involved me in their investigations as a consultant" .
After May 23, 1992, Cesari never returned to Palermo for sound assessments.
"That judge who assigned me the appraisals - he says -, the genius who wanted to set up the database of items, was gone".
