OKLAHOMA CITY (AP) -- A University of Oklahoma student has died after a snowboarding accident in Colorado.
Swedish Medical Center spokeswoman Julie Lonborg says William "Billy" Khourie III, wasn't wearing a helmet when the accident happened Tuesday afternoon at Breckenridge. Lonborg says the 22-year-old Khourie received a massive head injury.
The Elk City native died Wednesday night.
Authorities say the Breckenridge ski patrol was called to the accident on an advanced-intermediate trail at about 1 p.m. Tuesday.
The patrol took Khourie to Breckenridge Medical Center and was later transferred to Swedish Medical Center in Englewood, Colorado.
