PHOENIX — A 7-year-old boy hiking with his grandmother in northern Arizona found help on his own after the woman fell and broke her leg.

Firefighters said the boy and the 59-year-old had been walking the Constellation trail in Prescott National Forest on Thursday before the accident. There was no cell service on that part of the trail, she convinced the boy to go.

He walked a half-mile before he got to the trailhead parking lot, where he found two hikers, who called 911.

The boy then led the first responders firefighters to his grandmother.

A Prescott Fire Department press released praised the child’s determination.

“He was a capable, self-assured fellow who remained calm throughout the event and helped lighten the mood of everyone present,” according to department spokesman Conrad Jackson.

Another fire engine arrived with a wheeled rescue basket that firefighters used to take the woman to an ambulance for transport to a hospital.

The woman and child were not identified.

The woman was taken to Yavapai Regional Medical Center.
