If you've killed Frog Morton for Sheriff Marion in Redding, then you'll most likely come across this encounter at some point during the game. You'll typically be assaulted by four thugs and one of the following brothers: Toad Morton, Newt Morton, or Snake Morton.

All of the ruffians and each of the Morton brothers carries some decent weaponry. You can even grab yourself a rare H&K G11E off of Snake Morton, if you end up facing him.
