I have just been searching and searching for reasons as to why he would slip away so easily and unnoticed. I feel that TH the step mom set it up to have the grandfather lure him out the back door next to his classroom and they (the GF and Kyron) went "for a ride" -
Now I came to this theory after I read the Grandfathers website (Northwest tales) and his stories - some of which relate to Terri and children and animals and hideaways - and a particular hideaway named "Rolf's Hideout". I was also reading abother website the other day where a psychic kept hearing "wf" "woof" but could not discern what it meant - well - put two and two together - "Rolf" = "Woof", "Wf"
He had a straight shot up I-5N about a 5-6 hour drive. Plenty of time to get away. I have a feeling that he is alive and that someone is being "punished" for this be it Terri or Kaine - who knows. In his stories, he really didnt take to kindly to the squirrel and made references for her to "go away".
I feel he is safe and alive. Its my theory and only my opinion.
