O.K. It just does not ring true to me at all. I get the impression of a screen play for a really bad slasher film and not a manifesto. I don’t doubt the guy killed those people and himself but I think this was a red herring so no one would bother finding out the real motive beyond him being a nut case.
I agree. I don’t have the papers to qualify as some sort of expert. A nut case is a good an explanation as any other.
