National Border Patrol Council president George McCubbin said Sunday that the two sets of agents approached an area where a sensor had been activated. He says they arrived from different directions early Tuesday when Agent Nicholas Ivie opened fire.
Acting Cochise County Sheriff Rod Rothrock confirmed the scenario but would not say if Ivie was the first to shoot.
The shooting happened a few miles north of the border with Mexico, in a well-known smuggling area.
The FBI announced Friday that the shooting appeared to be a case of friendly fire.
