There are two bullet holes in the glass doors at the CVS Pharmacy across the street from the Centers for Disease Control headquarters in Atlanta. Law enforcement sources tell CBS News that one motive investigators are exploring is the gunman's belief in a COVID-19 vaccine conspiracy theory.

The officer who was injured in the shooting on Emory University's campus in Atlanta is dead, Interim Chief Greg Padrick of DeKalb County Police Department said. He died of his injuries from a gunshot wound, Padrick said.
