The Chaffee County Sheriff’s Office says Sgt. Collin J. Zak of North Royalton was found unresponsive Saturday morning on the expert-rated Mirage run at the Monarch Ski Area. Ski patrollers performed CPR, but Zak was pronounced dead at the scene.

He was wearing a helmet at the time of the crash.

Zak was a rifleman who was stationed at Colorado’s Fort Carson. Officials there say Zak had been in the Army for five years.
