It seems pretty certain that things do not take place in a vacuum.
That LE has allegedly stated they have a theory (think they know what happened)
tells me they might know some things that have never been made public.
We, not having access to that info, think we see only a blank wall
when we look for clues to unravel this case.

Swanson said police think they know what happened to her after
leaving school, but he declined to say what that was.
"We've got a fairly good idea of what transpired from the time she left the
school for at least the following few hours," he said. . . .'

If Kara was abducted the possibiliities are finite & I hope would/will be
investigated as much as possible.
If she were a runaway she might well have planned the move or she might not have
but either way you look for different types of evidence based on the
possibility being checked.
Whatever happened, the evidence or indication is/or was there to be seen &
interpreted. I just wish we all had access to that info.
side note:
I wish I knew someone that had known her well. I have a couple of simple questions.
