The Georgia Bureau of Investigation identified the man who opened fire at the Centers for Disease Control and Prevention as Patrick Joseph White. White died and a police officer was shot and killed.

"Kennedy is directly responsible for the villainization of CDC's workforce through his continuous lies about science and vaccine safety, which have fueled a climate of hostility and mistrust," one ex-employee wrote, according to the Associated Press news agency.

Patrick Joseph White has been identified as the gunman who killed a policeman before being found dead at the scene.
