Ok. I just read another story that leads me to believe he was bi-polar or somewhat autistic.
If this is indeed the case, then all of these off the wall theories flying around are just that.
Long hikes by himself doesn’t seem odd now. Changing his mind about Jacskon vs Jackson Hole doesn’t seem odd. Acting strange doesn’t seem odd. Indecision, mood swings, none of this seems odd.
Not to mention that the guy told Gabby he was hearing voices. That’s schizophrenia.
