I have been out of town for four days on business and come back to a "just-in-time-for-halloween" story. Wow.
I haven't read much on this story, but what I have gives me the impression that this Zachary Bowen guy was wacko long before what he did to Addie. What a selfish sick little boy in a man's body he was. Why couldn't he have just killed himself and rid the world of one more 'tormented' soul.
Just my opinion.
