Muhammad Youssef Abdulazeez, a 24-year-old Kuwait native, fired shots from an automatic rifle on a recruitment center and then a United States Naval Reserve Base. He also injured three others before he was killed by a local police officer.
Law enforcement officials were able to track a pattern of questionable behavior by the former high school wrestler and amateur mixed martial arts (MMA) competitor on both his personal blog and in his travel history.
