U.S. officials told ABC News an AWOL serviceman, identified by an FBI official as a Private First Class Naser Jason Abdo, was arrested Wednesday after making a purchase at Guns Galore in Killeen, Texas, the same ammunition store where Maj. Nidal Hasan purchased the weapons he allegedly used to gun down 13 people and wound 30 others on Nov. 5, 2009…

When he was arrested, Abdo was in possession of large quantities of ammunition, weapons and what appeared to be the makings of a bomb, according to early accounts from law enforcement. He had also apparently purchased an Army uniform with Fort Hood patches from a local surplus store.

Abdo told ABC News in 2010 he was Muslim and should not have to participate in what he called an “unjust war” in the Middle East.
