OMG, I didn't know he bought the fire starting supplies there! I didn't know what he bought or how they were linking him for sure to the fire. I guess at first I wanted to block out some of the horrifying details.

I don't think you were blocking out any details, I believe the identification of the supplies he bought is newly released information. I assumed they had good reason to identify this specific guy as the person of interest, but I've been reading everything I can about these crimes, and that was news to me. Makes perfect sense now as to why LE was so sure that this is who they're looking for.
