I'm sitting pat with my theories.
To me, the fact that LE has clammed up and not releasing any information is a red flag.
a) They have a suspect or big clue and they are following it and/or watching.
b) They know he walked away and are not letting that out.
c) They are chasing their tails.
Without any further additional information, we are chasing our tails.
Unless a bit of information is posted on FB or media and is verified by family or LE, I'm not going to get too excited about it.
When he is located, it will be interesting to see which theories were correct and what gut feelings led to them, and for those theories that were incorrect, where we went off track.
