The gunman suspected of targeting U.S. military service members during a mass shooting Friday in Tennessee was a 24-year-old electrical engineer who had grown up in Chattanooga as part of a conservative Muslim family.
Mohammad Youssef Abdulazeez was born in Kuwait but moved with his family to the United States as an infant after the start of the Persian Gulf War and became a U.S. citizen, according to accounts given by friends and one of his sisters.
He attended Red Bank High School, just outside Chattanooga, north of the Tennessee River. His senior yearbook entry featured two photographs of him - clean-shaven with close-cropped hair - alongside a prophetic quotation: "My name causes national security alerts. What does yours do?"
In high school, Abdulazeez was active as a wrestler, competing in the 189-pound weight class. He later fought briefly on the mixed martial-arts circuit, training at the Chattanooga Fight Factory, a local gym. A video of one cage fight from 2009 shows him pummeling a middleweight from Shelbyville, Tenn., winning in the second round on a technical knockout.
After graduating from high school, Abdulazeez remained in the area, earning his engineering degree from the University of Tennessee at Chattanooga in 2012.
