Disclaimer - This idea is a bit out in left field:
Does anyone out there think that there may have been a ransom-type letter sent to the family and that's why they are convinced she was abducted? Perhaps it included something (ie: her wedding ring) as proof that they have her. LE could be withholding this info from the general public.
There is just something nagging at me about this reward that is being offered up - people just don't offer up that type of $$ without some sort of reassurance that she could be alive.

I am beginning to think along those lines as
well. Or perhaps something was revealed in her phone records that suggested she was meeting with someone from her past who they now know abducted her and may be in contact with the family in some way ??
