The suspected gunman who attacked the Centers for Disease Control and Prevention's campus on Friday may have fired many hundred rounds, law enforcement said on Tuesday.

Investigators released new details on the shooting targeting the Centers for Disease Control. Officials say Patrick Joseph White had expressed "discontent" with the Covid-19 vaccine and fired hundreds of rounds at CDC headquarters before he died by suicide.

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.
