Two things to add - evidently these were not all folks from Mexico. Also it was reported that someone - maybe the coyotes themselves - were offering to sell these folks cans of soda for $10.00 a can.
Living in this area, I can tell you that it is some kind of miracle that any human being could exist under these conditions for 3 days.
These Coyotes should be stopped.
You're right, not all were from Mexico, and the desert area where they were found is far from the border.
This was reported on the news. My daughter heard about the coyote trying to sell a can of soda for $10. She started giggling. I didn't understand at first, then realized she didn't know what a coyote in that context was. She thought a four legged coyote was selling sodas.
