When I saw the headline about the fire - my first thought was someone intentionally started that fire. Perhaps even at the direction/request of the defendants. What better way to destroy uncovered evidence? IMO, LE was going to return to that house of terror at some point for additional evidence searches.
Even worse, they rigged trip wires to explosive devices around the property. It's assumed they wanted to kill or severely injure any fire fighters and law enforcement officers who came to put out the fire.
I hope LE installs some cameras out there.
