Authorities say Prescott firefighters rescued an injured hiker after her 7-year-old grandson went for help at her direction and reached other hikers who called 911.
The Prescott Fire Department said the woman didn't have cell service where she fell and broke her leg Thursday. She dispatched her grandson and he approached two other hikers at the trailhead parking lot about a half-mile away.
The boy then led the first responding firefighters to the grandmother and they began providing medical assistance.
Another fire engine with a wheeled rescue basket arrived, and firefighters used it to take the woman to an ambulance that took her to a hospital.
Identities weren't released but the department said the grandson was "a capable, self-assured fellow who remained calm throughout the event."
