There have been questions raised over a possible connection between Fast and Furious and the death of U.S. Immigration and Customs Enforcement agent Jaime Zapata on February 15, 2011. The gun used to kill Jaime Zapata was purchased by Otilio Osorio in the Dallas/Fort Worth Metroplex, Texas (outside the area of responsibility for the ATF Phoenix field division which conducted Fast and Furious), and then smuggled into Mexico. Congressional investigators have stated that Osorio was known by the ATF to be a straw purchaser months before he purchased the gun used to kill Zapata, leading them to question ATF surveillance tactics.
In addition to Otilio Osorio, a Texas-based drug and gun trafficker, Manuel Barba, was involved in trafficking another of the guns recovered in the Zapata shooting. The timeline of this case, called "Baytown Crew", shows guns were allowed to walk during surveillance that began 7 Jun 2010. On 20 Aug 2010 Barba received a rifle later recovered in the Zapata ambush and sent it with nine others to Mexico. The warrant for Barba's arrest was issued 14 Feb 2011, the day before Zapata was shot. On 30 Jan 2012, Barba, who claimed to be working with [[Los Zetas]] in illegally exporting at least 44 weapons purchased through straw buyers, was sentenced to 100 months in prison.
