Shep Smith said the Feds are working on five possible scenarios. From what we do know, he probably had a student visa but has not been confirmed as a student which is a big RED FLAG. Terrorism uses diversions. It may have been the plan to occupy the forces on the initial shooting. It has been reported that police were sent to an elementary school. The person of interest may have someone who helped plant disinformation.
I think when the cops interviewed witnesses, at the site of the first shooting, they interviewed the shooter (thinking he was only another witness) and HE supplied the misinformation himself. He had two hours to kill, why not give himself some additional cover? That pretty much seems to be the way this “investigation” is going.
