An Upton woman is dead following a head-on crash 16 miles north of Laramie early Sunday morning.

The Wyoming Highway Patrol says 25-year-old Stephanie Strong was traveling south on U.S. Highway 30 when a pickup driven by 18-year-old Aaron Clifford of Casper crossed the center line and hit her head-on.

It's unknown if Strong, who was ejected from her car, was wearing her seat belt.

Clifford was wearing his seat belt and was AirLifed to Cheyenne Regional Medical Center. His condition is unknown at this time.

Speed and improper lane use are being investigated as contributing factors in the crash. Charges against Clifford are pending.
