I completely agree! I live near a substance abuse treatment facility, and there have been many instances where people have left in the middle of the night and the helicopter has been out searching for them, and also I have had several appear on my porch at my door. I no longer open my door in the middle of the night without checking, and now since this case has unfolded I have installed a RING doorbell so I can check without being close to the door. However before we moved to our present home, we lived in a town similar to Barron, and I would have to say that if someone knocked on my door in the middle of the night I may have answered it, I know for a fact I would have had to walk to the door to see who was there, so I'm curious if the Closs's would have had to walk up to the door to see who was outside. I still feel it was someone that they knew and thats what brought them to the door. IMO
