FLOWERY BRANCH, Ga. -- State agencies are now investigating and one suspect is dead after a trooper-involved shooting in Hall County late Saturday.

It happened during Operation Thunder in the county - a multiple agency road check seeking drunk drivers ahead of a major summer holiday.

That's when the suspects fled the checkpoint near the intersection of Winder Highway and Sloan Mill Road officials said.

Two troopers then began to pursue the suspect's Ford Explorer which then fled up Interstate 985 to Queen City Parkway where the driver turned north toward Gainesville.

As the driver got closer to Industrial Blvd., officials said he began to drive aggressively, striking a trooper's vehicle and ultimately causing a wreck. At this point, two people exited the vehicle.

Now on foot, at least one suspect continued to run from officers for nearly a mile before they were able to catch up with him.

That's when the situation took a violent turn as he continued to fight the troopers attempting to subdue him. Soon, officials said the officer was forced to fire on - and ultimately kill - the suspect.

At this point, it's unclear why the suspect fled. Officials don't believe that the troopers involved in the pursuit suffered life-threatening injuries.

The Georgia Bureau of Investigation and the Georgia Department of Public Safety's Office of Professional Standards have been called in to investigate.
