On the night of December 14, 2010, a firefight in a remote Arizona canyon near Rio Rico left 40-year-old U.S. Border Patrol Agent Brian A. Terry dead. Terry was part of a four-man tactical team assigned to intercept armed rip crews that target drug smugglers. Terry was struck in the back by a round that severed his spinal cord and aorta and his injuries proved fatal despite efforts by colleagues who remained under fire.

Two AK-47-style rifles recovered at the scene were traced to the Bureau of Alcohol, Tobacco, Firearms and Explosives Operation Fast and Furious, a finding that drew intense scrutiny and became central to subsequent investigations. One suspect, Manuel Osorio-Arellanes, was wounded and taken at the scene while the others fled across the border. Over time, additional arrests and prosecutions followed; family members and colleagues described the death as a turning point in scrutiny of cross-border smuggling and weapons-tracing programs.

Does anyone have firsthand information about that night in the canyon or about the suspects who fled back to Mexico?
