A Mexican national claims to be the man who shot and killed U.S. Border Patrol Agent Brian Terry, whose death is tied to the “Fast and Furious” gun-walking scandal.
Gustavo Cruz-Lozano, who says he killed Terry, turned himself in on Wednesday on charges related to a separate incident: threatening to kill  Hidalgo County, Texas Sheriff Lupe Treviño.
But before he surrendered himself, Cruz-Lozano said in an exclusive interview with Univision News’ daily news magazine show “Primer Impacto” that he murdered Terry during a firefight on Dec. 14, 2010, while the agent was on patrol near the U.S.-Mexico border in Arizona. Two AK-47 rifles found at the scene were linked to the botched Operation Fast and Furious , in which the U.S. government sought to track firearms sales to violent drug cartels. But it remains unclear whether those weapons were used to kill Terry.
Cruz-Lozano, 41, was not one of the several suspects arrested in the aftermath of Terry’s slaying. But in an interview with Univision News, he insisted he is the one who pulled the trigger on Terry.
