On Aug. 9, at approximately 2 p.m., the Grand Canyon Regional Communications Center received a call from a park volunteer who was with an unconscious male hiker on the North Kaibab Trail approximately half of a mile below the trailhead.
The volunteer started CPR and when park rangers arrived on scene, they continued CPR and resuscitation efforts including the use of an AED (Automated External Defibrillator).
Their efforts to resuscitate Brice Henri Patricot, 63, of Precy-Sur-Oise, France, were unsuccessful.
Investigators learned Patricot was with five other people that had hiked to the Eye of the Needle approximately two miles below the rim. Three of the individuals in the group continued on past Eye of the Needle, while Patricot and his wife decided to return to the trailhead after breaking for lunch.
The temperature along the rim was approximately 73 degrees and the inner canyon temperature was approximately 83 degrees at the scene of the incident.
An investigation into the incident is being conducted by the National Park Service in coordination with the Coconino County Medical Examiner and an autopsy is being performed to determine the cause of death.
No further information is available at this time.
