County Coroner Pam Wells told the Fort Smith Times Record the shooting suspect, James Ray Palmer, 48, died at a Fort Smith hospital about 2 hours after the Tuesday afternoon episode.
Van Buren police Lt. Brent Grill told the newspaper Vickie Jones, the secretary to Circuit Judge Gary Cottrell, was recovering from a gunshot wound to the leg.
A Van Buren police officer, David Passen, was injured when the windows of his patrol unit were shattered as he pulled up to the courthouse, the Crawford County Press Argus-Courier reported.
Grill said Palmer had inquired about seeing the judge and pulled out a gun when told Cottrell wasn't in.
The receptionist and Jones fled toward the judge's chambers, where the secretary was wounded. Palmer then engaged in a shootout with officers outside the courthouse, Grill said.
"I believe as many rounds as [the suspect] was popping off, he was trying to shoot anything and everything," Grill said.
He said Palmer had an assault-style rifle and two handguns and was wearing a military-style vest but not body armor, the Times Record said.
