The same link you posted also states (and I do believe) is that 90% of child abusers are family members or family friends. Only about 10% are strangers. Astounding!

Pretty much the same as the murder statistics, huh?

Strangers who are interesting in children sexually do not often have access to children so they either take a job that gives them access (making them not strangers) or become friends with families with children (making them a "family friend")

Most likely to abuse the kid, mommy's boyfriend, (not family), second most likely to abuse the kid daddy's girl friend (also not family)

Even those who kidnap their victims often are known at least casually by the child. Makes it easier.
