I'm wondering if the length of time the perp/s seem to have been in the Closs house is because they were looking for something (NOT Jayme). For example, were there things missing that they might have taken to sell, such as TV or other electronics, jewelry, etc.? If course we don't know, but it seems to me that if there are obviously missing items, it might be good if LE put the word out on those things to alert pawn shops as well as the general public in case they show up pawned or for sale somewhere.
And not just stolen items ... could they have gone there to get something they felt the Closs family should not have? Not sure what types of things, but for example suppose the Closs parents bought something that someone else had not wanted sold, and refused to sell it back to the previous owner. Like a family heirloom that meant a lot to someone. Inability to get it back in what would feel like a normal way (Gee, I explained why I felt it needed to stay in my family.) could drive some otherwise stable (or not) individuals to rage.
This is just a line of speculation, not my theory, but any thoughts on this?
