Authorities make final arrest in border agent's killing

PHOENIX (AP) - The U.S. Attorney's Office says authorities in Mexico have arrested the final of several defendants accused in the killing of a U.S. Border Patrol agent whose death exposed a bungled federal gun operation.

Jesus Rosario Favela-Astorga faces first-degree murder and other charges in the December 2010 killing of 40-year-old Brian Terry in Arizona.

Favela-Astorga was a member of a crew that planned on robbing marijuana smugglers when it encountered Terry and other agents who were on a stakeout in the southern Arizona desert.

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