Shouldn't Frank be fleeing town at the end of the film? (spoilers)

Yes, I know, suspension of disbelief, but to anyone who can't see ghosts, he's incredibly suspicious in terms of his connections to the heart attack deaths. First Ray, a man he saw right before his death and argued with, dies, then a man in the exact same bathroom as him, and then the newspaper woman--who he seemingly "threatened" in a crowded museum, assaulted, kidnapped, and then got into a fatal crash with! And there's nothing at the end to suggest that the general public knows about Johnny committing the murders (though the sheriff seems to believe Frank), so unless the police found some way to convince the public that Patricia was behind it all or something, Frank should probably look out for an angry mob coming his way.
