I googled A. True Ott and there appears to be a lot of information about him. I looked at very little of it but I believe his credentials are, to put it mildly, questionable. Here is an excerpt from the only Web site I opened:

Satanic Child Sacrificing Rituals First Reported At Vatican And Now At LDS Temple In Salt Lake City

A.True Ott, excommunicated by the Mormon Church for his controversial research, says he experienced death threats trying to get at the truth behind deep-seeded corruption in U.S. government and LDS hierarchy. Satanic influences abound and corruption must stop in order to avert World War III, claims Ott in his upcoming book 'Free At Last.'
