The Georgia Bureau of Investigation identified the gunman as 30-year-old Patrick Joseph White, of Kennesaw, Georgia.

CDC security guards stopped White from driving into the campus on Friday before he parked near a pharmacy across the street and opened fire from a sidewalk. The bullets pierced “blast-resistant” windows across the campus, pinning employees down during the barrage. More than 500 shell casings were recovered, the GBI said.

ATLANTA — Law enforcement have released the photo of the gunman who fired hundreds of rounds at the CDC last Friday and killed a DeKalb County Police Department officer. The photo of the shooter, 30-year-old Patrick Joseph White, was put out by the Georgia Bureau of Investigation.
