ATLANTA (AP) — A Georgia man who opened fire on the U.S. Centers for Disease Control and Prevention headquarters, shooting dozens of rounds into the sprawling complex and killing a police officer, had blamed the COVID-19 vaccine for making him depressed and suicidal, a law enforcement official told The Associated Press on Saturday.

The Georgia Bureau of Investigation has identified the man in the deadly shooting at the U.S. Centers for Disease Control and Prevention as a 30-year-old from suburban Atlanta. A neighbor said he often spoke of his distrust of vaccines.

Police in Atlanta say the suspect is dead after a shooting near Emory University and the Centers for Disease Control and Prevention headquarters.
