Peter Riggs, the Nebraska man charged with first-degree murder in Iowa County for the shooting death of a maintenance worker at an Interstate 80 rest stop, also faces a weapons charge in Johnson County.

Riggs, 32, of Columbus, Neb., is scheduled to stand trial on the weapons charge Aug. 30 in Johnson County District Court. His pre-trial conference is set for Aug. 18.

Riggs is charged in the May 29 shooting death of Jeffrey McAdam, 46, of Victor, in the men’s rest stop restroom near Victor. McAdam died at the scene from a single gunshot wound.

A Johnson County sheriff’s deputy arrested Riggs about three hours after the shooting.

Court records show that the Johnson County deputy found a loaded 9 mm Ruger handgun inside a cooler in the front passenger area of Riggs’ vehicle and found a second 9 mm handgun in the trunk. A stun gun also was in the car’s passenger area.

Riggs told deputies he didn’t have a permit to carry the guns, a criminal complaint states.
