Hmm its a sad story and I do quite like the way that a pizza seems to be a key piece of evidence. On the whole it seems strange case to me and I would suspect foul play personally. All we can do is hope, but it having been 6 days already I don't hold out much hope at all really (I can't remember the statistics but after 24hours the chances of finding someone alive who has been abducted are very very low).
