The video shows a blue car stopped perpendicular on the exit ramp, and slightly off the roadway.
A Highway Patrol trooper can be seen standing outside that car's driver side door, while shielding himself behind his cruiser.
Two other unknown men are standing in front of the blue car when suddenly, the driver of the blue car reverses the vehicle, pulls forward and then drives away.
The trooper then runs and gets back into his cruiser and continues to pursue the vehicle.
WSOC notified the SBI and State Highway Patrol of the video and investigators with both departments expressed interest in viewing it.
Preliminary investigations showed Harris failed to stop his car when Saunders tried to pull him over for speeding on I-485.
An initial release from the Highway Patrol said Harris led the trooper on a nearly 8-mile pursuit that began on I-485 near mile marker 30, and ended outside Harris's home on Seven Oaks Drive in northeast Charlotte.
The release said Harris exited his car, and that that's when an encounter took place, leading up to the fatal shot.
The SBI has not yet clarified what that encounter was.
Harris was laid to rest Tuesday. His family has called for change, including a deaf alert that appears when police check or run a license plate.
The North Carolina Highway Patrol's manual shows that all troopers are trained in how to recognize that someone is deaf, as well as ways to communicate with them. In it is a warning saying, in part, "Keep your eyes on the person's hands. Deaf people have been stopped by an officer and then shot and killed because the deaf person made a quick move."
It's unknown if that's what happened in this case.
The SBI has yet to confirm the fact that Harris being deaf had anything to do with the pursuit and shooting. The only update, provided Wednesday, was that officials were still gathering video footage of the pursuit and shooting.
Records obtained by the Associated Press show that Harris previously faced a charge of obstructing a peace officer and a charge of resisting an officer. Both of those charges were dropped.
The AP also reports that Harris pleaded guilty to interfering with or resisting police in Connecticut.
Trooper Saunders remains on leave as part of standard procedure.
