• Pellegrino remains in stable condition in an Italian hospital, where surgeons closed his neck wound with nine stitches after he lost more than a liter of blood during the July 15 attack
• Italian police arrested four North African men from Tunisia and Morocco within hours of the assault and charged them with stabbing and related robberies
• Investigators say the suspects are linked to earlier attacks on an elderly man and a cabdriver before they boarded the train from Melegnano to Milan Bovisa
• The attack has intensified scrutiny of Italy’s record migrant arrivals by sea, prompting calls for stronger public safety measures
• Pellegrino’s colleagues and former students at Archbishop Riordan High School have raised over $38,000 through GoFundMe to cover his medical expenses and replace stolen items
