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

Authorities said Patrick Joseph White is the suspected shooter who carried out the deadly attack near the CDC headquarters and Emory University in Atlanta on Aug. 8, when police officer David Rose was killed.

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.
