The only ones I can think of would be the following:
- Running out of the house to escape an attacker
- Altered mental status, i.e., psychotic episode, delusional, etc.
- Staged disappearance
Aside from those three scenarios, if a person then comes up missing after having made a distress call,
the only logical explanation would be that the person went involuntarily missing.
Given that LE says they found signs of foul play at the cabin and that AQ remains missing, my main man William of Occam says that the overwhelming likelihood is that she's involuntarily missing.
What's more, William says that the reason LE found signs of foul play is because there was foul play.
