This is a human trafficking case if you read the article. Many were school age children. I think it is obvious many were mexicans but we will see as this progresses. Remember folks, this is happening within* Trumps rule and the republican's brightest 4 years. If u read the article you will discover the only reason they got  caught is because Wal Mart called the police. P.S. If it is a human trafficking case, *more than likely* some American or rich immigrant within the U.S. is buying them. P.S. If you go on my news feed you will also see the do wild horse slaughter B.S. Maybe they need the meat to feed the human trafficking victims!? (the rich fat cats)
