I bet there's an interesting story there. Judging by the sheetrock in the receptionist area of the building there was an attempt made at a business startup of some kind. Looks like they ran out of money because the new sheetrock didn't make it to the point where it got painted.

All the CRT's out back in the warehouse could have been related to that somehow.

It would be pretty hard to handle that many CRT's & TVs without leaving any fingerprints. That might be a starting point.

Maybe set up a couple of game cameras and check on them every so often to see if they turn up anything ?
