DEVELOPING: Two U.S. Border Patrol agents were shot, one fatally, Tuesday morning in an area in south Arizona known as a major drug-smuggling corridor, authorities said.
The identities of the agents were not immediately released, but the shooting occurred at the Brian Terry Station near Naco, Ariz., which is just south of Tucson. The station was named after an agent who was killed in the line of duty in December 2010. The area is considered a remote part of the state and sources tell Fox News that the shooting occurred about 8 miles from the border.
The injured agent was airlifted to a hospital with nonlife-threatening injuries.
The search for the killer is being led by the Federal Bureau of Investigation and the Cochise County Sheriff's Office.
Two weeks ago, the station was named after Brian Terry, who died in a shootout in December 2010 not far from Tuesday's shooting.
Two guns found at the scene were bought by a member of a gun-smuggling ring that was being monitored in the Fast and Furious investigation. Critics have knocked U.S. federal authorities for allowing informants to walk away from Phoenix-area gun shops with weapons, rather than immediately arresting suspects.
