Santino Di Matteo, also known as Mezzanasca, is an Italian former member of the Sicilian Mafia from the town of Altofonte in the province of Palermo, Sicily, Italy. Di Matteo took part in the killing of Antimafia judge Giovanni Falcone on May 23, 1992, near Capaci. After his arrest on June 4, 1993, he became the first of Falcone's assassins to become a government witness – a pentito. He revealed all the details of the assassination: who tunnelled beneath the motorway, who packed the 13 drums with TNT and Semtex, who hauled them into place on a skateboard, and who pressed the button.
Killing of son
In retaliation for Di Matteo becoming an informant, the Mafia kidnapped his 11-year-old son, Giuseppe Di Matteo, on November 23, 1993, on the orders of Giovanni Brusca and Leoluca Bagarella. According to a later confession by one of the kidnappers, Gaspare Spatuzza, they dressed as police officers and told the boy he was being taken to see his father, who was at that time being kept in police protection on the Italian mainland. Di Matteo made a desperate trip to Sicily to try to negotiate his son's release but on January 11, 1996, after 779 days, the boy, who by now had also become physically ill due to mistreatment, was finally strangled, and the body was subsequently dissolved in a barrel of acid — a practice known colloquially as the lupara bianca. The executors were Enzo Brusca, brother of Giovanni, Vincenzo Chiodo and Salvatore Monticciolo on the orders of Giovanni Brusca. In 1997, Di Matteo and Brusca met face to face during court proceedings. Bursting into tears Di Matteo told the judge: "I guarantee my collaboration, but to this animal I guarantee nothing. If you leave me alone with him for two minutes I'll cut off his head." The confrontation threatened to become violent, but court security guards restrained Di Matteo. Brusca had also asked Giuseppe Di Matteo's family for forgiveness. In October 1997, the pentito Di Matteo was rearrested. Although a key witness in several important trials underway, he had returned home to recommence his criminal activities and avenge atrocities carried out on family members.
Release
In March 2002 Di Matteo was released early, along with four others, in return for cooperating with magistrates, outraging relatives of Falcone, who stated that the system of pentiti safeguarded killers from prosecution for murder. Despite no police protection, he decided not to go into hiding but returned to his family in Altofonte, protected by an iron gate and two dogs. He tried to live a normal life in the town but was shunned by the townspeople. Before his arrest, Di Matteo had already become hesitant about the violent strategy of the Corleonesi. In their testimonies Di Matteo and another pentito, Salvatore Cancemi described the victory celebration that followed the Capaci bombing. Totò Riina ordered French champagne and while the others toasted, Cancemi and Santo Di Matteo looked at one another and exchanged a gloomy assessment of Riina and their future: "This cuckold will be the ruin of us all."
