You are right teddy - I am emotional on the subject, for my own reasons other than those of basic humanity. It was an apology of sorts (to you for misunderstanding my comments) but I stand by my thoughts on everything.
Unfortunately doc, I think you are right - it is a desperately sad, more than likely lost, cause. But as a mother of such a missing child, I don't suppose you would ever give up hope until someone found a body - alive or otherwise.
