On December 14, 2010, Border Patrol Agent Brian Terry was shot dead by a group of suspected drug cartel along the Mexican border in Peck Canyon, northwest of Nogales, Arizona. The guns used to kill Brian Terry were traced back to Operation Fast and Furious.
In September 2011 the Attorney General of Mexico confirmed 200 murders happened in Mexico as a direct result of Operation Fast and Furious.
In May 2012 another murder connected to Operation Fast and Furious surfaced. According to a congressional report released, Mario González Rodríguez, brother of the state attorney general of Chihuahua at the time, was also murdered by guns traced back to Operation Fast and Furious. The U.S. withheld this information from Mexican authorities for eight months.
The video below shows Mario González Rodríguez handcuffed and surrounded by masked men holding guns.
In July 2013 A high-powered rifle lost in the Fast and Furious program was used to kill a Mexican police chief in Jalisco state.
A gun from the failed U.S. operation known as “Fast and Furious” turned up at the scene of a shootout between Mexican authorities and alleged cartel gunmen earlier this month, according to CNN. U.S. officials told CNN at least one AK-47-style gun that could be traced back to the failed gun-walking scheme was found at the scene. The shootout on Dec. 18 left five alleged cartel members dead in Puerto Penasco, a popular tourist site in Mexico.
