The pdf didn't open right for me. However, I once read that something like 60% of all children killed before the age of twelve were killed by a family member. When friends of the family were included, the numbers jumped up into the 90% range. I lost that link when my computer crashed a few months' back, but I remember it distinctly. I agree that it makes the likelihood of the murderers being Damien, Jason and Jessie remote. Of course, that doesn't prove their innocence, but, IMO, it's another brick in the wall of reasonable doubt.
