former u.s. marshal service. it's one of the situations that you don't want to speculate about motive but we do know that the two targets in this specific case involve the united states military which raises a lot of suspicions. could be a crazy guy who hates the u.s. military or it could be something sin terister. >> that's correct. when you talk about the military it sounds like they had a motive. when you talk about maximum terror effect with all of the stuff going on with the military isis overseas threats, the concerns raising the threat level, if someone wanted to have maximum impact on the military and scared by it that's what they would do go to the military and do what this terrorist did. >> we don't know who this individual is or what the motive is if there was a conspiracy or anything like that. we'll get a lot more information at the top of the hour. we'll stay on top of this story.
