With limited information to work with it's very difficult to decide how and where to search for Katelyn.
I try and figure out the “why” someone is missing and then work from there. In this case there is no clear reason as to why she's missing so speculation based on the little bit of information and known evidence is all we have.
I go back to the last known communications..ie; the texts. I have to believe based on the timing of the texts and lack of supporting video evidence inside the mall, at the metro, and the airport that they must have both been lies not sent by Katelyn herself.
The luggage being discarded in the manner that it was further supports my original theory that this was an abduction. Imo.
But the peculiar staging is contradictory imo. Texts to look like a voluntary disappearance vs luggage to look like a kidnapping. This is all very strange imo.
Hopefully I'm wrong but for the purpose of searching all we can do is follow the evidence.
I hope that folks continue to look for Katelyn alive and well hiding out somewhere and getting it all together.
I would also continue looking for evidence in the area of the luggage discard and work from there.
This location should probably be checked;
