Seifeddine Rezgui, the young man who killed 38 people at a Tunisian beach resort on June 26, didn't show any signs of extremism until he joined an extremist group at his university in the historic city of Kairouan, NBC News reported. Rezgui's friends from his hometown said he "dressed normally," had a girlfriend and drank alcohol, and that his violent act came as "a shock." But fellow students at Kairouan said that once he fell in with the extremist group, he "wouldn't listen to other viewpoints," even threatening a female professor and a female student. Rezgui ultimately snuck into war-torn Libya in January, where he attended a militant training camp before launching his June attack.
