TUCSON, Ariz. -- A suspect in the 2010 killing of a U.S. Border Patrol agent has been extradited from Mexico and is scheduled to be arraigned Friday in Tucson.
Federal prosecutors say 34-year-old Ivan Soto-Barraza has been indicted on first-degree murder and other charges.
The slaying is at the center of the scandal over the botched U.S. gun-smuggling probe known as Operation Fast and Furious.
Prosecutors say Soto-Barraza is among five men charged in the Dec. 14, 2010 death of Agent Brian Terry near the Arizona border city of Nogales.
Terry allegedly was killed when armed robbers targeting marijuana smugglers opened fire on agents.
The death brought to light the federal government's botched gun smuggling investigation in which they planned to track guns sold to criminals who were buying them for weapon smugglers.
