Is he an immigrant? His family left a scribbled note on their door and it seemed like it was written in a way that wasn’t English as a first language.
He intended to kill more people and was prevented by her brother.
So it sounds like his motivation was to kill many Christians. I’m wondering if he was radicalized (and schizo).
I don’t think that was his family necessarily. I read it and thought he lived with roommates. I would credit our lovely public education system for the words and spellings that were used.
