PINE BLUFFS, Wyo. (AP) — Authorities say a woman is dead after she rear-ended a commercial truck on Interstate 80 west of Pine Bluffs.

Sgt. David Wagener says 32-year-old Randi Amen, of Scottsbluff, Nebraska, crashed into the truck early Sunday morning and died later at a hospital.

Investigators say Amen was traveling at a high rate of speed before the crash, and alcohol might have played a role.

The two people in the commercial truck, which was pulling a trailer, were not injured.

The crash marked the second highway fatality in Wyoming this year. There were seven fatalities by this time last year.
