KENNESAW, Ga. -- Police continue to investigate after an employee at a FedEx facility in Kennesaw shot six people this morning.
Cobb County Police Sgt. Dana Pierce said the man, who has not been identified yet, started shooting just before 6 a.m. and was found about three hours later, dead of a self-inflicted gunshot wound.
Pierce says the man was a package handler and sorter. Officers found his body in a loading bay with a shotgun.
Six victims were taken to WellStar Kennestone Hospital. Hospital officials said at a press conference that three of the victims are in critical condition: a 28-year-old man, a 22-year-old man and a 52-year-old woman.
A 38-year-old man is in stable condition, while a 19-year-old man, is pending release The sixth victim, a 42-year-old woman, has been released from Kennestone.
A seventh victim was taken to the hospital for an injury suffered while trying to escape the gunman. Pierce said that person was not shot.
Liza Aiken, who works at the facility, said she saw the suspect drop a knife shortly before he began shooting. She said he was dressed all in black with a camouflage vest, was carrying a weapon and "had bullets strapped to his chest like Rambo."
11Alive's Paul Crawley reported from the scene that FedEx employees were being turned away as they tried to arrive at work. Those who were already at work were held in a warehouse on the property. The facility was on lockdown and police closed several nearby roads, including Old Highway 41 between McCollum and Cobb parkways. All roads have since reopened.
Cobb County Police Officer Mike Bowman said investigators searched the area for secondary devices as protocol. Police used search dogs to go through the entire warehouse; that sweep uncovered no explosive devices.
Sgt. Pierce says police are also searching the suspect's car in the parking lot and it will take hours to process the entire crime scene.
Pierce says there is a security checkpoint at the FedEx facility, which is a half-million square foot sorting and distribution warehouse. It's not clear if the suspect started shooting before the checkpoint, or somehow got the gun through it.
Pierce says more than 100 officers responded from the Georgia State Patrol, GBI, FBI, ATF, Homeland Security, Atlanta Police, Gwinnett Sheriff's Dept., Fayette County officers, Acworth Police, Marietta Police and Kennesaw Police.
FedEx spokesman Scott Fiedler released a statement at around 7:20 a.m., saying, "FedEx is aware of the situation. Our primary concern is the safety and well-being of our team members, first responders and others affected. FedEx is cooperating with authorities."
At 9 :20 a.m. Fiedler issued a new statement saying: "We can confirm that an incident occurred early Tuesday morning at a FedEx Ground facility in Kennesaw, Georgia. Our thoughts and prayers are with those affected, and with their families and friends. We are grateful for the assistance of law enforcement. The situation is now stabilized and we are focused on the needs of our team members and cooperating with the law enforcement investigation of this tragedy."
