DeKalb County Police Officer David Rose was fatally shot Friday. The suspect, who a neighbor said had expressed anti-vaccine sentiments, was also shot and died from his injuries.

Officials are still investigating a shooting at the Centers for Disease Control and Prevention headquarters in Atlanta, Georgia, that killed a police officer on Aug. 8. The suspect, Patrick Joseph White, 30, may have been disgruntled over vaccine side effects before perpetrating the shooting, according to multiple reports.
