(TUCSON, Ariz) – Closing arguments are expected Tuesday morning for one of the seven men indicted for the 2010 murder of Border Patrol Agent Brian Terry.
Heraclio Osorio-Arellanes will appear in Tucson federal court.
Osorio-Arellanes was arrested in Mexico in April 2017.
Osorio-Arellanes is accused of pulling the trigger on the gun that killed 40-year-old U.S. Border Patrol Agent Brian Terry during a firefight on the Arizona side of the U.S.-Mexico border in December 2010.
Osorio-Arellanes is believed to have been part of an armed “rip-off” crew that was robbing drug smugglers along the border at the time.
Terry’s elite Border Patrol unit attempted to arrest the men when the gunfight broke out, leading to Terry’s death.
The investigation into Terry’s killing exposed the “Fast and Furious” operation, which was a U.S. Bureau of Alcohol, Tobacco and Firearms’ operation to allow known traffickers to buy guns in order to track the illegal flow of the weapons.
ATF agents lost track of about 1,400 of the more than 2,000 weapons involved in the operation, including two that were discovered at the scene of Terry’s shooting.
Seven men were indicted on charges in connection to Terry’s death.
Rosario Rafael Burboa-Alvarez is serving a 27-year sentence for first-degree murder. Officials say he was not at the scene, but assembled the rip crew.
Manuel Osorio-Arellanes pleaded guilty in 2014. He is serving a 30-year sentence in connection to the murder.
Jesus Leonel Sanchez Meza was convicted by jury in 2015 and is serving a life sentence.
Ivan Soto-Barraza was convicted by jury in 2015 and is serving a life sentence.
Jesus Rosario Favela Astorga is charged in connection to the murder and is awaiting extradition to the U.S., from Mexico.
Rito Osorio-Arellanes pleaded guilty to conspiracy. Officials say he was not at the scene. He is serving eight year sentence.
