At a tourist site no less.

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 last 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.

The now-defunct Fast and Furious program began in 2009 and was run by the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF). Agents allowed low-level weapons purchasers to cross the Mexican border in an attempt to expose trafficking routes used by Mexican cartels. But the agency ultimately lost track of some weapons, including two found at the scene of the killing of a border patrol agent in 2010.

The ATF acknowledged that weapons from the operation would likely continue to turn up at crime scenes.
