Jeff Williams, CDC director of security, showed Channel 2's Michael Doudna the shattered windows and glass that went flying as employees took cover Aug. 8.

There is still damage, reminders left from the day nearly two weeks ago. The shooter was at the nearby CVS when he aimed at the CDC and fired hundreds of rounds.

"He found a location where he had a good visual of CDC facilities and potentially CDC staff," Williams said.

The blast-resistant glass, installed after the Oklahoma City bombings, helped prevent more extensive damage.

First responders went floor by floor, marking doors as clear to ensure everyone was safe. People can see what they did in the aftermath of the shooting, busting down the doors, going room to room.

Mona Patel, who has since returned to the office, noted the difficulty of seeing broken glass on colleagues' desks.

"I think we're resilient. I believe we're here to support one another," Patel expressed, highlighting the community's strength.

Repairs are currently underway at the guard house, with similar repairs expected for all six buildings that were hit.

DeKalb County Police Officer David Rose was killed when he responded to the active shooter call. His public memorial service is scheduled for Friday.
