I'm one of those posters who is inclined to think ET did (at least initially) go with TC willingly. I also think her willingness might play a very important part in why they haven't been located yet. In other words, her mindset matters, imo. That said, she is 15 years old. That is still a child in the eyes of the law. 15 year olds don't just get to decide when they will leave home. And there's a damned good reason for that law being put in place. 15 year olds don't know jack about life (I could have said this more eloquently, but that's really what it boils down to in my opinion).
In terms of who is responsible for this whole mess, the blame gets put squarely on the adult's shoulders, imo. THAT is what makes ET the victim and TC the perpetrator.
Mr. Tad Cummins is the 50 year-old criminal wanted by the TBI. Ms. Elizabeth Thomas is the 15 year-old victim who needs to be rescued.
1 --- What could determine TCs capture? Knowing the nature of their relationship, as they see it!
2 --- Does TC need to have total control? If TC has to exercise total control at all time, they have to be always together otherwise the victim escapes. The pictures of them together help.
3 --- Do they help each other while in the run? If ET could go by herself fetch food and water, people need to start watching a woman instead of a couple. Yes, ET is the victim
but if she went into this willingly, then they are more agile and will evade surveillance longer.
4 --- Why does it take so long? They are on the run for over 3 weeks. It is time to think differently.
5 --- Could it be the case that they move separately? May be it is time to look for a couple, albeit odd; look of a single man, perhaps looking much slimmer now; look for a single woman, perhaps looking much older now.
6 --- Could it be the case that they get help from a third person? A WS member suggested that such helper is probably a woman. In my view, it could be either gender. Assuming that a woman helps them, may be we should look for two women, one of which is the victim; perhaps, looking for a couple, the man being TC; or may be three persons moving around as an older couple with a grown daughter, perhaps at a Walmart store, again!
Let us see if our (TBI, sleuths, family members, etc.) collective mind is smarter than the combination of their two minds to resolve their mystifying disappearance.
