They move to different places like they're bulletproof!

This was one of the most irritating aspects of the film. Yeah, they make a big point that two of the girls are bumming around the country and no one knows where to expect them. But these folks kill an awful lot of people, and this is the sixth place they've lived! That there aren't cops looking for them in multiple cities, all the time, is pretty far-fetched. I can't imagine stuffing dead bodies in my basement, then blithely moving away the day after a missing girl's relatives come to talk with me about her, and simply changing my name to Thompson. Feh.
