A Scottsbluff woman was killed in a one-vehicle accident late Saturday night in Wyoming, about 6 miles south of Glendo.

Wyoming Highway Patrol Sgt. Stephen Townsend says 36-year old Gabriell Palmer was northbound on I-25 about 11 pm when she lost control of her vehicle on black ice.

Townsend says the vehicle rotated clockwise, going off the right side of the roadway, down a steep embankment, and overturning when it struck a ditch at the bottom. Palmer was killed despite wearing a seatbelt.

Troopers investigating the accident attribute the accident to going too fast for the existing conditions, with very worn tires a contributing factor along with very worn tires.
