Very good possibility, but him hanging around to continue shooting others leaves questions in my mind. Heard that someone who heard the shots said they believed they heard up to 20-30 shots fired. Unless he used a AR-10 type 308, that's a few reloadings. Anyone with an ounce of sanity who wanted this particular trooper dead, would have fired and GTF outta there. Not this boy, he fired at EMS folks which means he hung around.
