UPDATE: (CNN) -- Three of the six people treated at a hospital after today's shooting at a Georgia FedEx facility are in critical condition, a doctor told reporters.
Two of those have life-threatening injuries, said the emergency room doctor at Wellstar Kennestone Hospital.
The doctor released no names, but identified the patients as: A man, 28, in critical condition and in surgery Tuesday morning; a woman, 52, in critical condition and in surgery Tuesday morning; a man, 22, in critical condition; a man, 38, in stable condition; a woman, 42, who was treated and released; and a man, 19, who was treated and whose release was pending.
ATLANTA, Georgia (CNN) -- A FedEx package handler went on a shooting rampage early Tuesday at his workplace in suburban Atlanta, wounding six people -- one of them critically -- before turning the gun on himself, police said.
"That individual is deceased here at the scene," Cobb County Police Department Sgt. Dana Pierce told reporters. Police were sweeping the area with search dogs to ensure no secondary devices had been planted.
Pierce would not release the name of the employee, who was found with a shotgun. "That was the only weapon that he had at that time," Pierce said. "As far as I know, he worked at this location."
The facility is a large warehouse located in Kennesaw, Georgia, about 21 miles northwest of downtown Atlanta.
Earlier, FedEx spokesman Scott Fielder told CNN that the situation had stabilized "and we are focused on the needs of our team members and cooperating with the law enforcement investigation of this tragedy."
The victims were taken to Wellstar Kennestone Hospital, where at least one person was undergoing surgery, hospital spokesman Tyler Pearson said.
"Numerous" 911 calls from inside the half-million-square-foot package and delivery facility alerted police to the shooting at 5:54 a.m., Pierce said.
