Quoted from pezpunk:considering they grabbed an old bed, some random tools, and some crappy chain link fencing i think it sounds like random thieves who likely have no idea what they have. his best hope is that they go online to check if its worth anything before they smash it for the scrap metal.
Another horrible thought, assuming they know nothing about pinball machines they probably have no idea how to move a pin properly without damaging it. So, I want to add I hope they did not destroy the BBB because I want to stay positive and wish ya best of luck that you WILL get it back.
