Man to be Arraigned in Arizona in Border Agent’s 2010 Slaying

U.S. officials say that a man sought in the slaying of a Border Patrol agent in Arizona eight years ago has been extradited to the U.S. from Mexico.

Federal authorities said Tuesday that Heraclio Osorio-Arellanes will be arraigned in U.S. District Court in Tucson on Wednesday. Osorio-Arellanes had been in custody awaiting extradition since being arrested by Mexican authorities on April 12, 2017.

Osorio-Arellanes is charged in the death of Border Patrol Agent Brian Terry, who was shot and killed Dec. 14, 2010 when he and other agents encountered a gang preying on smugglers north of Nogales, Arizona.

Three of six other defendants charged in the case have pleaded guilty and two were convicted following a jury trial. Another defendant has not yet been tried.

Osorio-Arellanes will be charged with first-degree murder in the December 2010 killing.

The killing of Terry revealed the "Fast and Furious" operation, in which U.S. federal agents allowed criminals to buy firearms with the intention of tracking them to criminal organizations. But the U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives lost track of most of the guns, including two that were found at the scene of Terry's death.

The operation set off a political backlash against the Obama administration and led the agent's family to sue.
