I think you and others posted this a couple times over the last week or so. Why it's being questioned and doubted now I don't know. It was eventually confirmed by the very person who started the fire, although in his first interview with investigators he never mentioned a fire, just made it sound like he ate dinner, watched some TV, went to bed. Think there might have been a reason Avery never mentioned the bonfire to investigators?
Yes I agree, has SA since come back and denied the fire was that night? If not I don't know why anyone can doubt it. It doesn't matter who didn't mention it, perhaps they didn't think of it. SA himself said there was a fire that night. BDs pants had bleach stains on them, he certainly helped SA out with something that night. I agree that he perhaps didn't mention it right away for a good reason.
