I am really surprised that more hasn't come out about him. No family, no friends, no real co-worker interviews that I have read. No one stepping up to say he is innocent or he couldn't be involved or he was "such a quiet guy," etc.... Usually, you'll at least see something in comments on news articles and such that say I knew him or I went to school with him, etc..., but I have seen nothing outside of the girlfriend's bil and one co-worker that said he was nice, but a little off. Wonder if he has family in the area?
ETA: I did read comments about the arson at the parent's house. Are they still around? Does he have other family? Friends?
