WOOD RIVER, Neb. (AP) — Officials say sheriff’s deputies checking on a dump truck stopped on railroads tracks in central Nebraska found the driver dead inside the cab.

The discovery was made about 6:25 a.m. Friday. Officials say 64-year-old Gary Rouse, of Gibbon, died of a medical condition while driving a Mack dump truck in Wood River.

Investigators say Rouse was eastbound on Highway 30 when he had a medical issue that caused him to leave the roadway and come to rest on the railroad tracks.

He was pronounced dead at the scene.

No other vehicles were involved.
