A driver who died in a single-vehicle rollover crash east of Rock Springs Tuesday morning may have fallen asleep at the wheel, the Wyoming Highway Patrol says.

The crash happened around 6:30 a.m. near milepost 9.1 on the Interstate 80 Service Road.

The patrol says 29-year-old Salt Lake City, Utah resident Samuel S. Roberts was headed west when he failed to negotiate a left-hand curve, went off the road, and rolled his SUV approximately four times.
