 Most of the guns went to the Sinaloa Cartel, while others made their way to El Teo and La Familia.Although most weapons were purchased by suspects under 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.
