[OT] Fraudster shows up at someone's door and refuses to leave without money

This is one of the weirder crime stories I've heard in a while.

What were these people THINKING? Why on earth would they fork over $4500 to some guy who insisted he was owed money? There's nothing in the story that implies he used force or the threat of force to get the money but it appears the homeowners knew his demands were bogus.
I can only assume they were incredibly stupid, incredibly gullible or that he had some kind of blackmail that he could apply against them. But the fact that they'd called the police afterwards, suggest that they know they were being scammed and had no fear of what the police might find out about them if they responded to their call.
As usual, the crime reporting in this area is abysmal and gives virtually no information that would make this make sense, including the answers to obvious questions.
