A surveillance photo of a man suspected in the beating of a 60-year-old National Park Service employee Wednesday was released by Cochise County Sheriff's officials.

Karen Gonzales, a uniformed maintenance worker with the Park Service and a longtime seasonal employee, was found unconscious Wednesday afternoon in a picnic area restroom at Chiricahua National Monument.

Gonzales suffered head trauma and was airlifted to a Tucson hospital, where she remained in critical but stable condition, Park Service spokeswoman Michelle Fidler said.

Gonzales’ government vehicle was found several hours later about 40 miles away in Douglas by tracking the worker’s cellphone, which was still inside.

Anyone with information on the case or who can identify the man is asked to call sheriff's authorities at 1-520-432-9500, said Carol Capas, spokeswoman for the Cochise County Sheriff's Department, on Friday.
