The gunman who opened fire Friday at the US Centers for Disease Control and Prevention broke into his father’s safe to get the five firearms recovered at the scene, state investigators said Tuesday, as some CDC workers seeking answers and reassurance from leadership were left dissatisfied by a short agency-wide meeting about the shooting.

The Georgia Bureau of Investigation identified the gunman as 30-year-old Patrick Joseph White, of Kennesaw, Georgia.

The man who attacked the CDC headquarters in Atlanta on Friday fired more than 180 shots into the campus and broke about 150 windows

Documents from the shooter’s home showed his discontent with coronavirus vaccines, authorities said. CDC workers want RFK Jr. to denounce vaccine misinformation.

Four CDC workers, who were not authorized to speak publicly, told CBS News under the condition of anonymity that they were "deeply disappointed and frustrated" by an apparent lack of leadership following Friday's shooting​.
