The more pictures I see, the more convinced I am of it not being an accident (not that I ever thought is was). There’s simply not that much damaged by fire. Sure some wooden beams are burned but the walls are mostly just smoke damage and there are large sections not damaged at all. Is that a rubber maid type container on the right side? As in rubber... as in it’s gonna be the first thing burned and melted?
Seems to me the neighbors (has who called been confirmed?) called 911 too early and the fire department got there too quickly, if you know what I mean, and “they” are sticking to the story line as planned.
