Two teen girls from Scottsbluff, Neb. are dead after a crash just over the Wyoming border.

The Wyoming Highway Patrol identified the victims as 18-year-old Alexis B. Wheeler and 19-year-old Hallie J. Anderson. They were among six people riding in a Sierra pickup that crashed just before midnight Wednesday on Wyoming Highway 92, one mile west of the Nebraska state line.

The patrol said the 22-year-old driver, Ethan Kaufman of Cheyenne, was trying to negotiate a slight left hand curve when the pickup drifted off the right side of the highway and went into a drainage ditch. It collided with a driveway and flipped end-over-end.

Investigators are looking at whether speeding and alcohol use played a role in the crash.
