TUCSON, Ariz. (AP) — A man charged with killing a U.S. Border Patrol agent during a 2010 firefight near the Arizona-Mexico border is scheduled to change his plea in federal court.
Manuel Osorio-Arellanes, a Mexican national, had previously pleaded not guilty to murder and other charges in the December 2010 death of Border Patrol Agent Brian Terry.
Two rifles bought by a gun smuggling ring that was being monitored by the government's botched investigation known as "Operation Fast and Furious" were found at the shooting scene.
But authorities have declined to say whether the murder weapon was linked to an Operation Fast and Furious purchase.
Authorities say Terry and other agents came under attack by Osorio-Arellanes and four other men who had come to the U.S. from Mexico in order to rob marijuana smugglers.
