On 6 April 1993, Mafia turncoat Tommaso Buscetta told Palermo prosecutors that he had learnt from his boss Gaetano Badalamenti that Pecorelli's murder had been carried out in the interest of Andreotti. The Salvo cousins, two powerful Sicilian politicians with deep ties to local Mafia families, were also involved in the murder. Buscetta testified that Gaetano Badalamenti told him that the murder had been commissioned by the Salvo cousins as a favor to Andreotti. Andreotti was allegedly afraid that Pecorelli was about to publish information that could have destroyed his political career. Among the information was the complete memorial of Aldo Moro, which would be published only in 1990 and which Pecorelli had shown to General Carlo Alberto Dalla Chiesa before his death. Dalla Chiesa was also assassinated by Mafia in September 1982.
