A shooter described as being armed with an assault rifle and having bullets strapped across his chest opened fire Tuesday morning at a FedEx station outside Atlanta, wounding at least six people before police found the suspect dead from an apparent self-inflicted gunshot. "He had bullets strapped across his chest like Rambo, a huge assault rifle and he had a knife," Aiken said. (AP Photo/Atlanta Journal-Constitution, Brant Sanderlin) (The Associated Press)

The father of a gunman who wounded six colleagues in an Atlanta-area rampage says his son didn't seem enthusiastic about his job but never mentioned problems with co-workers.

Geddy Kramer showed up with a shotgun early Tuesday morning at the FedEx package-sorting center where he worked. He shot a security guard, then fired on those working in a large warehouse before killing himself.

Scott Kramer, who lived with his son, spoke to reporters on Wednesday. The father says Geddy Kramer didn't express a lot of enthusiasm about his job.

Cobb District Attorney Vic Reynolds said co-workers at the FedEx center reported Kramer to company management for shining a laser scanner at people's eyes. Reynolds didn't know if the conflict factored into the attack.
