Turns out the campus cop was ambushed by the shooter when the cop stopped another individual for a traffic violation. Cop never even got out of his car. Apparently the shooter (a Radford University student) came out of nowhere & unloaded on the cop.
Tragic - 39 yrs. old, leaves behind a wife & 5 kids.
No motive has been released. The shooter had apparently stolen a car from a real estate agency earlier that day at gunpoint.
Never underestimate the power of small minds in large groups.
