Etymology of 'coyotes' - ppl smugglers

Why are persons who work in the human trafficking industry referred to as coyotes?

I am just guessing, but the popular perception of coyotes is that they are sneaky. somewhat cowardly animals who kill livestock and pets at night when the owners are asleep. Most people have a negative perception of coyotes (the animal). Since coyotes are plentiful in Texas and other border regions, it seems like a natural fit (people smugglers have a reputation for being sneaky con men who would let people die for a few bucks- definitely a negative image). The people smugglers are also called “polleros” (chicken wranglers).

neat, thanks! I tried reading a bit about the animals before posting but couldn’t quite make the connection.

Possibly it’s because they keep falling off cliffs.

If you’re trying to sneak across the border, never hire the coyote with the ACME products. That’s just asking for disaster.
