ATLANTA (AP) — Investigators identified a 30-year-old man from suburban Atlanta on Saturday as the person who opened fire on the U.S. Centers for Disease Control and Prevention, killing a police officer and spreading panic through the health agency and nearby Emory University.

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.

NEW YORK (Reuters) -Grappling with the aftermath of a shooting that killed a police officer and left nearly 100 shattered windows, leaders at the Centers for Disease Control and Prevention held virtual meetings with employees on Tuesday to rebuild trust at the agency's Atlanta headquarters.
