 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 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 and to suspect a Texas-based operation similar to Fast and Furious.
