The bulletin, issued May 24 by the Nebraska Information and Analysis Center and later obtained by The World-Herald, said Al-Kazahg told another Marine that he would “shoot up the battalion, starting at the barracks,” if he were disciplined for certain misconduct. According to the bulletin, he also mentioned specific Marines he wanted to target.

The bulletin quoted NCIS as reporting that Al-Kazahg had previously made “suspicious statements” and been reported for “suspicious activity.” It said he had previously “shown various people large amounts of cash” and an online order he had placed for body armor, magazines, weapons parts, holsters and medical supplies, all to be shipped to a Nebraska address.

The bulletin also cited a caution about Al-Kazahg issued by the Lincoln Police Department in 2016 (before he enlisted in the Marine Corps) alleging that he was “dangerous, has an infatuation with guns and violent acts, and has a dislike for law enforcement.”

Al-Kazahg had made no threats specific to Nebraska, the bulletin said.

Al-Kazahg’s vehicle was stopped at the StratCom Gate, on Capehart Road, at 6:39 p.m. May 31. Law enforcement authorities haven’t said why he showed up at Offutt that Friday evening.
