That's the problem with people having snakes like this as pets. They get too big to handle and they turn them loose in areas like the warm South where these things can survive.
Unfortunately it's becoming a real big problem concerning venomous snakes in that area. People get all kinds of venomous snake via the internet from other countries and now they turn them loose or they escape here in the US.
Some nasty critters crawling around now that we never had before.
