Alcohol use is being investigated as the contributing factor in a fatal crash early Friday `morning. The single vehicle crash happened at 2:40 a.m. on US Highway 310 approximately 4 miles south of Lovell, Wyoming.

39 year old Louis L. Muckley of Basin, Wyoming, was driving a large pickup truck southbound on US 310 before the truck left the road to the west in a slight left hand curve. After reentering the highway, it began to spin across all lanes of US 310 to the east. After leaving the highway for a second time, the truck tripped and rolled several times.

Mr. Muckley was not wearing his seat belt and was thrown from the truck and died at the scene.
