A woman from Mills died in a highway crash Friday night. Wyoming Highway Patrol Sgt. Stephen Townsend said the crash happened on U.S. Highway 16 near Osage and identified the woman as 78-year-old Velma M. Thorne.

Friday night crash near Osage:

"This was on U.S. 16, about four miles northwest of Osage, which is in Weston County, about 8:20 pm, it involved two vehicles that were westbound on U.S. 16."

Sgt. Townsend said that Thorne was a passenger in a vehicle hit from behind by a pickup driven by Dwane Canfield of Upton, and that the setting sun might have been a factor in the crash.

Drivers blinded by setting sun:

"The roadway in that area is uphill and at a hill-crest, so the setting sun was making for very poor visibility, apparently, and the rear vehicle didn't see the vehicle in front of him, which was traveling at a slower speed and he rear-ended that vehicle."

The crash is still under investigation.
