Dahir Adan was a quiet and studious 20-year-old who came from a humble and well-known Somali family in Minnesota. Saturday night, in an unexplained fit of rage, he put on a private security uniform, headed to the Crossroads Center mall in St. Cloud, and pulled a knife, slashing, stabbing and injuring 10 people before he was fatally shot by an off-duty police officer, the Minneapolis Star Tribune reports. The stunning attack, in which Adan — a Somali refugee who moved to the U.S. with his family when he was 3 months old — reportedly referred to Allah and asked at least one victim whether they were Muslim, is being investigated as an act of terrorism.
Federal and local authorities are scrambling to find out whether Adan acted alone and whether he had any connection to foreign terrorist groups. On Sunday, a media agency for the Islamic State in Iraq and the Levant (ISIL) took to Twitter to claim credit for the assaults. St. Cloud Police Chief William Blair Anderson said investigators have yet to find evidence that Adan was radicalized or communicated with a terrorist group or acted with others. Adan’s family and those in the Somali community who knew him struggled to make sense of Saturday night. “We are in deep shock as everyone else is in the state of Minnesota,” the family said.
