Any ideas what this poor kinked snake is?

[Bluebonnet Herp]

OP, I highly suggest getting that animal away from that owner and finding an interested breeder in CA, the last thing we need is someone to find that burm in a shipping box across the border, in the hands of a child, or in a backyard.

I don't see why anyone has to buy it. If this fool's arrested, by all means he deserves it. We don't buy from petco or bad breeders, why buy from stupid craigslist sellers? He doesn't deserve anybody's money.
The only exception is if you can rescue it for free or dirt cheap. ($10) If not, spam his/her email for being an idiot.
