One of the articles at the above linked site said that the Ramseys had mentioned this guy to authorities bafore he was an official suspect or person of interest, whatever.
Which seems to indicate there was some kinda of contact, and that takes the matter out of the realm of speculation, into the realm of real possibility, even probability.
Who knows? Maybe the creep was hangin out at her pageants or something.
That whole kid beauty pageant thing is, IMHO, kinda on the sick side...
Do they have a DNA match?
