No one has ever been convicted for the killing of Scaglione and his driver. In January 1991, the suspects
Gaetano Fidanzati, Pietro D’Accardio,
Gerlando Alberti and his son, Francesco Russo,
Salvatore Riina,
Luciano Leggio and
Giuseppe Calò were not brought before the court by the prosecution for lack of sufficient proof. During his long career in the judiciary Scaglione was involved in some of the unsolved political mysteries that tainted post-war Italy. He was the last one to have interrogated
Gaspare Pisciotta, the right-hand man of the Sicilian
bandit Salvatore Giuliano, held responsible for the
Portella della Ginestra massacre on
May Day 1947 to impede the advance of communist and peasant movement. He was also the last one to have seen the journalist
Mauro De Mauro, who disappeared in September 1970 following his investigations on the mysterious death of
Enrico Mattei and on the
Golpe Borghese, a right wing coup attempt. De Mauro was allegedly murdered by the Mafia to cover up these events and possible political connections. Some observers claim Scaglione had been involved to keep these mysteries under wraps. Recent historical research, however, describes Scaglione as an honest judge. ==Mafia involvement==
