Mall Attacker was Recent College Student and Security Guard 20 Sep 16

ST. CLOUD, Minn. (AP) — He was a recent college student and had worked part time as a security guard. He was said to be a high school honors student. He had nothing more than a minor traffic citation on his record.

But on Saturday, for reasons still unclear, authorities say Dahir Ahmed Adan went to a central Minnesota mall and cut or stabbed 10 people before he was shot and killed by an off-duty police officer.

Little new information was released Monday about the 20-year-old Adan. But authorities are investigating the attacks as a potential act of terrorism.

A Somali community advocate who spoke with Adan’s parents said he was going to the mall to pick up an iPhone.

Those who know Adan say he was a calm, cool guy, and they are trying to figure out what pushed him to violence.
