Quoting MunchkinWrangler:" Oh god that poor kid. Did the man say why he took him? At least they know where they are and that he is okay. They just need to set perimeter and find a way in. Can they not dig?"
there was a rumor he said he just wanted media attention so i believe thats one reason they arent giving this situation much, and giving many details out just incase he has access down there to see whats going on above ground. the boy is okay though they communicate through the pipe, and also sent down crayons and his medicine through it. and im sure they could dig but obviously the guy would hear, and they dont want to chance setting him off to maybe harm the child
