If you can come out of this with a few mites and perhaps a minor RI, it will be a blessing. Thank goodness the reptile community is so tight knit and take care of our own. Personally, I am not surprised by their stupidity at all. These days stupidity runs rampant and common sense doesn't exist. I hope with all my heart the last two snakes are quickly accounted for and your babies are returned to the person who loves them dearly.
I certainly hope these people are punished severely, although my gut says not likely. Perhaps at the very least, they'll think twice about doing something this stupid again. Yeah, I don't really buy that either.
