Paying off a gambling debt really isn't so far fetched. Without a body or any DNA anywhere I think the assumption should be that she is alive some place. In which case, then why would someone take her? To pay off a debt could be a possibility. jmo
Well that is my point too...where's the body? It seems that one of these ass****s would have talked...and they haven't.
Other possibilities? Kidnapped.
Then again...this might be bigger than we all think.
