The Georgia Bureau of Investigation revealed new details during a Tuesday morning press conference about the suspect in the CDC shooting last week. FOX 5 Atlanta has also obtained a 911 call made by the suspect's father after the shooting.

GBI Director Chris Hosey told reporters the shooter, 30-year-old Patrick Joseph White, was armed with five firearms that belonged to his father. The shooter had no known prior criminal history.

Law enforcement officers collected more than 500 shell casings and five firearms from the scene of Friday's shooting that killed DeKalb County police officer David Rose near the CDC's Clifton Road headquarters and Emory University.
