A neighbor who knew the man suspected of opening fire at a FedEx warehouse says that the 19-year-old had often joked about shooting up his workplace.

Authorities say the suspected shooter, identified as Geddy Kramer, was found dead inside the building with a self-inflicted gunshot wound.

Hundreds of law enforcement swarmed the scene Tuesday after police say Kramer opened fire at the Atlanta-area warehouse just before 6 a.m. EST. According to the Associated Press, a witness said that the gunman was carrying an assault rifle, knife and had bullets strapped across his chest "like Rambo."

Police also found several homemade explosives around the facility, but none had been detonated.

At least six people were injured, with injuries ranging from minor to requiring surgery.

One of the injured, a 28-year-old man, remains in critical condition after surgery. A 52-year-old woman also had surgery, but officials say she is stable. Among the others hurt: a 42-year-old woman and two men ages 38 and 19.

Some who knew Kramer told CBS Atlanta that after news of the shooting broke, it wasn't hard to put two and two together.

"I remember Geddy would always joke around about shooting up his workplace," Lucas Dziedzic told CBS Atlanta. "I know he joked about it, and when I saw what happened on the news it added up it was him."

Dziedzic told CBS Atlanta that he was the one who helped get Kramer the job at FedEx.

Kramer's girlfriend told CBS Atlanta that he struggled with depression.

CBS Atlanta published a statement from the Kramer family. Full text below:
