As investigators probe what compelled Muhammad Youssef Abdulazeez's rampage that killed four Marines, RadarOnline.com takes an in-depth look at the mysterious 24-year-old.
Here's a shot of Muhammad Youssef Abdulazeez during his time at Red Bank High School, where he competed on the wrestling team.
Abdulazeez, a devout Muslim who was born in Kuwait, made a snarky reference to terrorism in his yearbook, writing, "My name causes national security alerts. What does yours do?"
Former classmates such as Kagan Wagner remained stunned at shocking turn of Abdulazeez, seen here in a boxing stance. "He was friendly, funny, kind ... I never thought in a million years that it would be this guy," she told the Times Free Press.
The Hixson, Tenn. native poses here with relatives; his father Youssuf is a soil engineering specialist for the city's Public Works Department, the paper reported.
Abdulazeez had dabbled in mixed martial arts -- competing and winning in a July 2009 match at an event called Chattanooga XFN II, according to mixedmartialarts.com.

The then-19-year-old beat an opponent via knockout.
The seemingly-normal and relatively-trouble-free upbringing of Abdulazeez, a college graduate at the University of Tennessee at Chattanooga, has officials and the public confused about his horrific actions in killing four military men.
In what would be his only arrest, Abdulazeez was taken into custody April 20 in connection with DUI, as arresting officers said he reeked of booze and marijuana, and had mysterious white powder by his nose. He was subsequently released on $2,000 bond.
Among the victims of the shooting were Gunnery Sgt. Thomas Sullivan, a veteran who fought in the Iraq War and was awarded the vaunted Purple Heart.
Officers survey the damage in the aftermath of the massacre. Federal officials said Abdulazeez's name had never surfaced in reports on suspicious individuals.
According to Fox News, a number of Twitter accounts affiliated with ISIS made light of the ghastly attack, which came ahead of the end of Ramadan.
