We know they were supposedly there.. but declaring it not a crime scene for the beginning and sticking with that all along is compelling! Especially in view of the outcome!
There was no crime, no foul play and they never once moved from that position. They could have camped out for a week there, taken cartons of prints, photos and more bodies even..
The reason we are here still is because....
it was NOT a crime scene, never was going to be no matter what they had to do to insure it wasn’t.
sure we can at least can reasonably assume so, from the time spent in the room
