I dont know that LE's silence indicates inaction. We know that these folks had electronic items in pretty good supply, GPS, cell phones, computers, highly placed postions with stable well known employers. We have computers at work, what kind of cell phones which may be like small computers etc....there is a lot to process here. We have one side of the story , ie: DH's, which has to be coroberated or refuted by evidence...it is not a 48 process, more's the pity. We have friends and family on both sides with divergent opinions. We know that the close bio family members of each side are likely to defend their loved ones...using that lens, how do you prove which side is more accurate.
It is a big job, there is a big area to search IF it is determined her disappearance is not voluntary.
JMO.
Just to let you know...
Hearing that from someone with as many posts as you have really is reassuring...it seems like so many days have gone by...we have thought exactly this, but then it seems like they should have some results by now!
That you seem to have "been around" enough to able to say that it's not such an un-usual LE silence-time, helps a great deal
