A .50-caliber rifle recovered from the hideout of drug lord Joaquín "El Chapo" Guzmán is reportedly one of the firearms lost by the U.S. government's gun-smuggling operation Fast and Furious.
Agents from the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) checked serial numbers of weapons recovered after the raid earlier this month on the Los Mochis house where Guzman was staying. They traced one of two rifles back to the ATF program, according to Fox News.
Thirty-four of the weapons sold through Fast and Furious were .50-caliber rifles, sources told the news outlet, which reported that Guzman placed guards on hilltops to shoot down helicopters.
The notorious drug lord escaped from a Mexican prison last year. Mexican authorities raided his safe house on Jan. 8, and he was recaptured later that day. Video of the raid showed a volley of gunfire as marines searched for the fugitive.
The botched Fast and Furious operation was intended to track straw purchasers of firearms, but ATF officials lost track of the guns. One of the guns was later tied to the shooting death of a Border Patrol agent in Arizona and multiple other weapons were linked to crimes.
The program sparked a major fight between congressional Republicans and the administration during President Obama's first term.
