DENVER (AP) – Authorities have identified a man killed while skiing in Colorado as a 19-year-old Kansas State student.

The Mineral County Sheriff’s Department has identified the victim as Garrett Spencer of Hesston, Kansas. He was skiing with friends when he hit a tree at the Wolf Creek Ski Area in southwestern Colorado.

Resort owner Davey Pitcher told The Denver Post that the accident happened Saturday on a green run. He said the victim was skiing without a helmet.

Mineral County Sheriff Fred Hosselkus said Spencer received almost immediate attention, with a nurse happening by the scene. The ski patrol was alerted and arrived shortly. Attempts at CPR all the way down the slope failed.

An autopsy was planned for Monday.
