After pleading guilty to first-degree murder, Manuel Osorio-Arellanes of Mexico has been sentenced to 30 years in prison over the death of US border agent Brian Terry. Osorio-Arellanes, 37, said that he was part of a group of five people trying to steal marijuana from drug traffickers on Dec. 14, 2010. That group clashed with the US Border Patrol, and Terry was killed in the ensuing gunfight.
Osorio-Arellanes didn't identify Terry's shooter, but he acknowledged it was someone in his group, CNN reports. In a plea deal, US officials agreed not to seek the death penalty, though Osorio-Arellanes could have been sentenced to life in prison, the Los Angeles Times notes. Two others have also been detained in connection with the killing, which has been linked to the US "Fast and Furious" operation. Two guns from that operation were discovered on the scene.
