I was on the BBC News website and it's got some samples of the comments left on the daughter's facebook. The spelling, etc amused me a bit.
I especially liked:
"An I hope they dont find any mor an your just havin a week somewer with your dad or sumink."
"Please be okay, otherwise I dunno wat ill doo."
"Plz b ok kirstie. We r all thinkin bowt u."
I think I've just got that Monday feeling.
