There were just as many people all over that thread that attempted to rationalize the unusual circumstances of this death by pointing to how quickly fire can spread, why someone would be awake or in the basement or difficult to reach by firefighters at 3am with zero evidence as well.
Point is, I found it just as baffling as to why so many felt compelled to explain away the strange elements of the initial story as I would if someone said something totally outlandish with no evidence as well.
