The two brothers, along with their spouses and kids, were at home. The Maglianese opened fire as soon as they saw them, killing Maurizio and leaving Mario standing but escaping. Not only did the families of the two Proietti get alarmed, but so did all the residents of the street, and the police quickly came on the scene. Colafigli and Mancini started a firefight and sought safety inside the apartment of another family when they heard the sirens arriving, but they were both taken into custody. Colafigli was spared prison time due to his mental illness, but Mancini received a 28-year prison sentence.
Prosecutors were led to believe that Colafigli was the one who carried out the attack, according to a dream in which a cat resembling Giuseppucci gave him the order to murder the Proietti. Mancini’s sentence was lowered and he was sent to many jails because to De Pedis’s assistance and connections. Fernando Proietti was slain on June 30, 1982, by Edoardo Toscano and Roberto Fittirillo, bringing an end to the Proietti war. In the meantime, Mario Proietti escaped two attempts on his life.
Giuseppucci’s death left the Banda della Magliana without a true leader, despite the fact that his original intention was to establish an organization without bosses. Nicolino Selis regarded this as his chance to take charge of the group. Due to his close relationship with Cutolo, Selis was vocal about his desire to take the gang leadership at the end of 1980 while he was incarcerated. Then, in the beginning of 1981, Selis got a cargo of 3 kilograms of cocaine from the Sicilians; however, he chose to divide it unfairly, taking 2 kg rather than 1.5 kg. When Toscano learned what Selis was up to, he could take it no more and concluded that Selis ought to be slain.
Toscano made the decision to gather the other associates for a meeting. The meeting was held in front of the Fiera di Roma on February 3, 1981, and Colafigli, De Pedis, Mancini, Abbruciati, Abbatino, and Pernasetti were there. Since Selis intended to speak with Mancone, who had stayed at home, he did not attend the meeting. Following the meeting, Toscano and Abbatino proceeded to Mancone’s residence, where they fatally murdered Selis. It is reported that in order to hasten the decomposition process, Selis’s body was placed into a pit at the edge of the Tiber and smeared with caustic acid. His remains have never been located.
Despite Selis’s strong association with the Camorra, the Neapolitan mafia chose not to exact revenge on his killing in order to prevent a conflict with the Banda della Magliana and to minimize the possibility of future reprisals.
