Probably Mongolian.
..or from Kiribati
You know every time I read something like this (did not/would not/could not specify countries of origin, my antennae goes up and I get so furious at these PC A*holes who refuse to share any information with us (as if that fact rises anywhere near the level of being classified) less, we learn that some or many, may actually be from countries that wish to do us harm. Then, we would really get p*ssed and that is probably why someone (of importance no doubt /sarc) made this "command" decision to withhold this information.
As an aside, why does there NEVER seem to be any "leakers" who will provide "us" with the type and kind of information we could benefit from (such as where these illegals are from) such as that which is being fed to the NY Slimes?
