Interesting article at Pajamas Media on the death of Jaime Zapata, the federal agent who was slain in Mexico. One of the guns recovered from the scene was a Draco AK pistol that could not be linked to Fast and Furious; because it came from an FFL in the Dallas Field area.

The same article also notes a large number of Houston area weapons turning up in South and Central Mexico. In light of knowledge that Houston-area Carter's Country shops were cooperating with the ATF by making sales to suspected straw purchasers, it does raise an interesting question to how many of those firearms "got away" or whether there was another deliberate decision to walk guns into Mexico at the Houston and Dallas offices as well.
Still too early to say; but definitely some interesting leads to investigate.
