On Wednesday, the Yavapai County Sheriff's Office announced that their days-long search for 74-year-old hiker Donald Hayes from Prescott Valley — who had last been seen on a Mingus Mountain trailhead on May 13 — had ended. His body was "found in a rugged area that had been difficult for searchers to reach," police wrote in a statement. "Mr. Hayes' dog Ranger who was with him on the hike, was found alive having remained with the victim," they wrote, noting that the dog was transported to a local animal hospital for treatment. Authorities found Hayes' body on Mingus Mountain about six miles from the distance of the trailhead, sheriff's spokesperson Kristin Greene told CBS News and the Associated Press. However, due to terrain, Greene told the outlet that the distance would take twice that time to hike. "He was definitely far, far away from civilization," the spokesperson said.
