Dozens more weapons recovered at crime scenes across Mexico, including a brutal 2010 massacre of teenagers, have been linked to the botched Operation Fast and Furious.
While some Mexican authorities estimate 300 of their citizens have been injured or killed by Fast and Furious guns, little has been known about those weapons south of the U.S. border until now.
Through the Mexican Freedom of Information Act, Spanish-language network Univision and Fox News obtained a list of 100,000 weapons recovered in Mexico in 2009 and 2010. The guns were then compared with the serial numbers of the 2,000 guns sold in Fast and Furious.
Univision identified a total of 57 more previously unreported firearms that were bought by straw purchasers monitored by ATF during Operation Fast and Furious, and then recovered in Mexico in sites related to murders, kidnappings and other actions by Mexican hit men and drug cartels.
