investigation by the program, there have been reports of at least one instance of ATF agents being directly involved in the transfer of weapons. On April 13, 2010, ATF Agent John Dodson, with assistance from Agents Casa and Alt, directed a cooperating straw purchaser to give three guns to Isaiah Fernandez, a suspected gun trafficker, and had taped the conversations without prosecutor approval. After being instructed by his superiors to obtain approval from prosecutors (albeit retroactively), Dodson's proposal was later rejected by his immediate superior David Voth, although he later received permission from Voth's supervisor after submitting a written proposal for the program. On June 1, 2010, Dodson used $2,500 of ATF funds to purchase six AK Draco pistols from local gun dealers, which he then gave to Mr. Fernandez, who reimbursed him for the expense of the guns, plus $700 for his assistance. Two days later, Agent Dodson went on a scheduled vacation without interdicting the weapons. As a result, the weapons were never recovered, no arrests were ever made, and the case was closed without charges being filed. According to the DOJ OIG report, Agent Dodson, as the undercover posing as a straw buyer, was not expected to surveil the weapons after hand-off to Fernandez. Other ATF agents followed the weapons to a storage facility; then surveillance was terminated without interdiction. The Fernandez case was dropped from Fast and Furious after it was determined that Fernandez was not connected to Mexican cartels and had ceased buying guns for resale. Aftermath and reaction Fate of walked guns Since the end of Operation Fast and Furious, related firearms have continued to be discovered in criminal hands. As reported in September 2011, the Mexican government stated that an undisclosed number of guns found at about 170 crime scenes were linked to Fast and Furious. Reflecting on the operation, Attorney General Eric Holder said that the United States government is "...losing the battle to stop the flow of illegal guns to Mexico," and that the effects of Operation Fast and Furious will most likely continue to be felt for years, as more walked guns appear at Mexican crime scenes. In April 2011, a large cache of weapons, 40 traced to Fast and Furious but also including military-grade weapons difficult to obtain legally in the US such as an anti-aircraft machine gun and grenade launcher, was found in the home of Jose Antonio
