The DeKalb County Police Department identified the officer killed Friday while responding to a gunman near the Centers for Disease Control and Prevention (CDC) headquarters in Atlanta, Georgia, 

Officer David Rose, 33, was shot and killed while responding to the shooting at the CDC campus, which prompted a shelter-in-place order for nearby Emory University. The suspected gunman, who has not yet been identified, was also killed.

Rose was rushed to Emory University Hospital on Clifton Road, where he died from his injuries.

He began working for the police department last September, the agency said, and is survived by his pregnant wife and two children.

CDC Director Susan Monarez said the agency was “heartbroken” over Friday’s deadly events.

“A courageous local law enforcement officer gave their life, and another was injured, after a gunman opened fire on at least four CDC buildings,” she said in a statement. “DeKalb County police, CDC security, and Emory University responded immediately and decisively, helping to prevent further harm to our staff and community.”

Federal and state officials said they were horrified by the shooting and expressed appreciation for law enforcement’s swift response. Among those sharing statements about the tragic incident was U.S. Sen. Raphael Warnock, D-Ga.

“I am mourning the tragic death of the officer who was killed in the line of duty today, and I am praying for the officer’s family and friends. Atlanta law enforcement saved countless lives, and we are grateful for their service,” Warnock said.

The Georgia Bureau of Investigations (GBI) is leading the investigation into the shooting and the FBI’s Atlanta office said it will assist.
