Did Anton go back and kill the trailer park lady?

The one who wouldn't give Anton info as to where Llewelyn worked. I can't recall what I heard said, while Tommy Lee was discussing the case and some of the random shootings going on, I thought he said something about a "desk clerk" or something like that being shot. I wasn't sure who he was referring to.
Did that mean he returned to kill her for snootily telling Anton she wouldn't help him? Who was the clerk mentioned being killed?
