GOODYEAR, Ariz. -- Coconino County sheriff's deputies and detectives are investigating the death of a Goodyear man who apparently was trying to run/hike to the summit of Humphreys Peak in Flagstaff on Saturday when he collapsed.

According to the sheriff's office, two hikers found John Greer, 53, unconscious and not breathing about a quarter mile beneath the summit at the 12,000-foot level. They called 911 and performed CPR for more than 30 minutes but were unable to revive Greer.

The county's Search and Rescue coordinator and volunteers hiked to the location of the victim and confirmed he was dead.

Due to the extreme elevation and rugged terrain, the Arizona Department of Public Safety Air Rescue helicopter was not able to land. Instead, a long-line rescue was performed.

The victim's body was transported to the Coconino County Medical Examiner's Office.

Greer's family said he was an avid runner and hiker and was high-altitude training in the Flagstaff area in preparation for an upcoming race.
