Murphy and Arabella leave Murphy's friend's cabin (right before he's murdered by Joan Freeman) and that very evening, Arabella sees a newspaper with the heading "Escaped Cop Kills Again". The newspaper even writes that Arabella is his accomplice. However, there's no reason for the police to assume that the murderer was Murphy. Joan Freeman shoots the victim with his own rifle, not Murphy's gun. Moreover, it's highly implausible that the police could even know about a murder in a very remote cabin in the woods, make inquiries and somehow mark Murphy as a suspect, and get the story into the evening papers, all in the space of a few hours.
