I meant to post this a few weeks back, but finally remembered to do so...
Perhaps I'm misremembering, but I believe there is a discrepancy between reporting on the SV podcast and what was said on the Unsolved Mysteries episode about the last people who allegedly saw Josh the night he disappeared. If I'm remembering correctly, Josh saw someone he knew on campus after he left the poker game? Or was this earlier in the day/evening? Based on what the Unsolved Mysteries episode said, the couple saw someone matching Josh's description (clothing) and not that either of the two knew him or positively/definitively identified Josh. Anyone else have thoughts or insight here?
