The problem I have with statistical probabilities though, is there are always outliers. If 90% of criminals of a certain type fit within a strict profile, it means 10% do not, for example. We know that there are several characteristics of Jacob's abductor that defy the odds - he wore a mask, he left witnesses, he used the threat of a gun, he was waiting in an isolated area.
Remember also, that the Abbey implemented a sexual abuse policy in February of 1989. They wouldn't have brought this on without an underlying problem behind it. Could "talk" of this policy driven an offender off campus? Who knows. Furthermore, Wetterling investigators (FBI) did investigate the monks at the Abbey in the beginning of the investigation, and then again later (Stearns Co) when other allegations surfaced at SJU.
The other possibility that could link the abductor to the Abbey is that Jacob's abductor may himself been a victim of sexual abuse.
