You just got a steal at the art gallery or taken a car from the lot at an unbelievable price now these items have been taken from you, who could or would commit such a crime? Maybe the same place you brought them from. For these “businesses” know where you live (credit application, Motor Vehicle report, paperwork etc) and they know the great deal that you received as well as what they could receive if it was suddenly put back in their arms. Now all they need to know is some skilled individuals who would happen to return to them without permission. Wild conspiracy theory could be but it also could be the truth or a great idea for a movie.
