BENTON, Ill. (AP) - An Army veteran who authorities say threatened to go on a shooting rampage at a Veterans Affairs hospital in southern Illinois has been indicted on a gun charge.

A federal grand jury in Benton indicted 29-year-old Mark Harmon on one count of attempted possession of a firearm on federal property with the intent to commit a crime.

Tuesday's indictment replaces a criminal complaint that accused him of having a handgun last month outside the VA hospital in Marion after calling a nurse and saying he planned to "fill that place with lead."

Authorities say they found a loaded Glock 23 semiautomatic handgun and a magazine filled with 13 bullets in Harmon's truck.

Harmon, who had been stationed at Fort Campbell on the Kentucky-Tennessee state line before being discharged, is jailed without bond. 1 of his public defenders declined to comment Wednesday.
