Traini said the attack was revenge for the murder of Pamela Mastropietro, an 18-year-old local girl whose dismembered body had been found a few days earlier, stuffed into two suitcases and dumped in the countryside. For this, Innocent Oseghale, a 29-year-old Nigerian national and failed asylum seeker, had been arrested and charged.[4][5]
Aftermath
Traini was a member and former local candidate of Lega Nord (LN), and many political commentators, intellectuals, and politicians criticized the LN's leader Matteo Salvini, accusing him of having spread hate and racism in the country. Anti-mafia writer Roberto Saviano labeled Salvini as the moral instigator of the attack.[6] Salvini responded to critics by accusing the centre-left coalition government of responsibility for Mastropietro's death for allowing migrants to stay in the country and having "blood on their hands", asserting the blame lies with those who "fill us with illegal immigrants".[7]Marco Minniti, then Italian Minister of the Interior, condemned the attack, saying that no political party must "ride the hate".[8]
During the 2019 Christchurch mosque shootings at Al Noor Mosque and Linwood Islamic Centre in Christchurch, New Zealand, Traini's name was written on one of the weapon magazines of the perpetrator, Australian Brenton Harrison Tarrant, alongside other far-right mass murderers and killers in addition to historical figures and battles. Tarrant also named Traini as among the shooters and killers that he supported because they "take a stand against ethnic and cultural genocide".[9] Traini dissociated himself from the event, declaring himself to be regretful about what happened in Macerata.[10]
The Prosecutor's Office of Macerata formulated against Traini the accusation of massacre aggravated by the purpose of racism, in addition to other crimes, including unlawful carrying of firearms.[11] On 3 October 2018, Traini was sentenced to 12 years in prison with a summary judgment.[12]
