Chattanooga gunman who killed four marines was amateur MMA fighter

The man responsible for the murderous rampage and killing of four marines in Chattanooga, Tenn., also had a past in combative sports.

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.

Several news outlets were able to confirm, through multiple pictures and video, that Abdulazeez competed in MMA. Following graduation from Red Bank High School in Hamilton County, he debuted in the Tennessee fight promotion Chattanooga XFS against Timmy Hall, who he defeated in the video here. He also took silver in the North American Grappling Championships.

Abdulazeez was described, in reports, as a "quiet" kid, who was a "devout Muslim and a good athlete."

In April, he was arrested for driving under the influence.

In a post obtained by The Daily Beast, via Daily Mail, Abdulazeez wrote on his blog, "If you make the intention to follow Allah's way 100 per cent and put your desires to the side, Allah will guide you to what is right."

The vicious attack came on the eve of the last day of the holy Muslim holiday Ramadan. Local law enforcement agencies around the country, like the NYPD, have since beefed up security around recruitment centers and landmarks.
