Not a white guy? No gun?
Eh, nothing to see here, folks.
More info. A freshman girl witnessed it and avoided giving ethnic description. Said the suspect was walking quietly and calmly with backpack. Appeared he stabbed randomly during the lunch hour by a food truck. One victim slumped over an outside table. Suspect walked up behind another student and stabbed him.
