ATLANTA (AP) — Investigators may never know what motivated a FedEx employee to shoot six co-workers at a suburban Atlanta sorting center before fatally shooting himself, a police spokesman said Thursday.
A note left behind by the gunman, Geddy Kramer, doesn't shed light on his motive, Cobb County police Sgt. Dana Pierce said.
"There is no rhyme or reason that anyone could pull out from that suicide note," Pierce said.
Statements from some of Kramer's co-workers initially led police to believe he might have been retaliating against co-workers or the company, but the investigation hasn't turned up evidence to back that up, Pierce said. Investigators are still reviewing evidence, he added.
Three of those shot have already been treated and released. Doctors on Thursday upgraded the condition of Christopher Sparkman, the 28-year-old security guard who was the first person shot and who suffered the most serious injuries, from critical to serious after several surgeries. Two others also remained hospitalized: a 52-year-old woman in stable condition and a 22-year-old man in good condition.
Sparkman's wife, Jamie Lynn Sparkman, thanked the community for well wishes and prayers and asked for privacy.
"My husband, Christopher Sparkman, is out of surgery and by the grace of God on the road to recovery," she said in a statement. "The recovery process will be a long one, but he will have the love and support of his family each step of the way."
Kramer, 19, showed up early Tuesday morning with a shotgun at the FedEx package-sorting center where he worked. He shot a security guard, identified as Sparkman, then fired on those working in a large warehouse before killing himself, authorities have said. The assault sent workers running, ducking and hiding as they tried to escape the gunman.
Kramer's father, Scott Kramer, on Wednesday told reporters outside the house where his son lived with him that he can't offer any explanation for his son's actions. Geddy Kramer left for work at the same time as he usually did and gave no indication that anything was wrong or different, his father said.
The family doesn't keep guns in the house, and Scott Kramer said he didn't know where his son got the gun used in the assault. Police have said Geddy Kramer bought the shotgun and that investigators found the box it was sold in, but police declined to say where the gun was purchased.
