"What we saw from the video and what we know now is that we heard the one shot and it startled the officer. He retreated for cover and returned fire."
The subject, whose identity has not been released, was pronounced dead at the scene. Harrison says the incident unfolded quickly.
"When he arrived around the other side of the car, the subject was on the driver's side on the ground. So, it was very fast."
He says a firearm was found next to the subject's body. Officer Carter, who was not injured, will be reassigned pending the outcome of the investigation. Harrison says it's unclear why the subject fired at the officer as the traffic stop seemed to be routine.
"You can hear him mentioning the license plate as he was giving commands to the suspect. So, apparently it was for some type of license plate violation that we think, right now."
