This is not a theory of mine but wanted to throw this out there to maybe reinforce the fact that we are still missing many pieces and it is impossible to "make sense" of it all without all the details.
Some are assuming Zenya worked until 7:00 PM and returned home a short time later. At first glance, the reports COULD indicate a short time frame BUT what IF Zenya worked until 3:00 PM and did not "get home" until 7 PM or so and What IF her time was unaccounted for or there are questions surrounding that?? That COULD leave a 4 hour or so window of time. That is IF you believe that there are not other details/communication regarding AH prior to the Official First report by Zenya.
If the reports gave specifics to the above, it could point to many theories and possible outcomes. In addition, it could also explain why the FBI is/remained involved. Investigators follow the leads and facts until they are documented and run down. If a piece is not validated/confirmed, it is pursued further.
What IF they believed the initial report is not 100% factual and they can't confirm yet?? COULD they be investigating other theories? COULD they believe AH IS/WAS outside NH for some reason?
Some of the recent posts/links point to the FBI update where they state they are making progress and have pursued Social media leads but they have not produced significant info etc.. That COULD indicate a stranger abduction, an accident, "opportunist" type or other dispositions not connected to anyone she communicated with routinely. It COULD also indicate involvement of someone close to her that would not require constant social media contact because they have personal contact/communication. That part of an investigation would rely on facts, timelines and accountability for persons that fit that criteria.
COULD the changes on the facts about being at home first, then not being at home etc have something to do with investigating/confirming information. If a piece of information becomes contradicted by factual information....
Same with the 6:30 PM Phone call(s), later changed. Reports were out there that the phone was used hours after AH wast last seen...COULD that have been explained at first and then disproved later?
