Officials say Allen allegedly sent a written manifesto to family minutes before the event and that investigators believe he intended to target administration members. Acting Attorney General Todd Blanche indicated investigators are still probing motive and note the suspect is not cooperating.
Media reports link Allen to part-time teaching at C2 Education and list degrees in engineering and computer science on his LinkedIn. Family members told authorities he made radical statements, practiced at shooting ranges, and owned firearms stored at his parents’ home. He faces federal counts including use of a firearm during a crime of violence and assault on federal officers.
