Six people have been injured after a shooter opened fire at a FedEx center near Atlanta. At least one of the injuries is said to be critical.

USA Today reports:

The victims -- including one in critical condition -- were taken to Wellstar Kennestone Hospital. Police found the suspect dead of an apparent self-inflicted gunshot wound while sweeping the area, according to Cobb County police spokesman Dana Pierce. One witness identified the suspect as a baggage handler, WXIA-TV reports. He is believed to have been armed with a shotgun and a pistol.

The gunman reportedly went through the normal security checks on arrival at the facility Tuesday morning, the Atlanta TV station reports.
