Pure speculation. :*)
LOL! Oh yeah,MUCH flimsier evidence than "I don't like the look in his eye",or "I think the father may have been involving the girl in the swapping". Let's see,"who should I listen to,John Walsh who has a national reputation and contacts with the police chief,or the professionally-paranoid who see Satan hiding behind every tree?". Gee,a REALLY tough decision,but I'll have to go with Walsh.
