BISBEE, Ariz. (AP) — A 60-year-old National Park Service employee was critically injured in an apparent assault in southeastern Arizona and her government-owned truck was later found in a border town about 40 miles away, authorities said.
A Park Service interpretive worker was found unconscious Wednesday afternoon in a picnic area restroom at Chiricahua National Monument, apparently suffering from a head injury, the Cochise County Sheriff's office said.
The woman was flown to a Tucson hospital where she was in critical but stable condition, but further information on her injuries was not immediately available, sheriff's spokeswoman Carol Capas said.
The woman's government vehicle was found several hours later in the city of Douglas by tracking the worker's cellphone, which was still inside.
No suspects have been arrested or identified, she said.
Capas said the worker's pickup was found in the middle of Douglas and there was no immediate evidence that whoever abandoned it had crossed the border into Mexico.
Douglas is about 40 miles south of the monument, which is in mountains and desert on the east side of a broad valley that runs north from the U.S.-Mexico border.
The region is used by drug smugglers as well as people entering the United States illegally.
"We do have significant foot traffic and vehicle traffic that's attributed to illegal activity," Capas said.
Deputies were working closely with federal and state law officers to " identify the suspect(s) who apparently seriously injured a federal employee," Cochise County Sheriff Mark Dannels said in a statement released by his office.
