GILA BEND - Authorities say four bodies have been found in the desert near Gila Bend, but there's no immediate word on their identities or nationalities.
The bodies were discovered Thursday morning along Interstate 8.
Sheriff's officials said they didn't know yet if the bodies are those of illegal immigrants who didn't survive the desert's brutal heat. Authorities say the Gila Bend area has been a pathway for traffickers headed to Phoenix.
A report this month showed deaths of migrants entering the country illegally along the Southwest border have averaged 150 a year since 2002.
