It was a quiet spring morning in Idyllwild, California - April 7, 2017 - when 25 year old David O’Sullivan put on his backpack, stepped onto the Pacific Crest Trail, and vanished.
The Irish hiker had come to America chasing a dream: to walk from Mexico to Canada, alone, through some of the country’s wildest landscapes. The day before, he’d sent a brief email from the town’s small library - his last known communication.
Since then, there’s been nothing. No calls. No confirmed sightings. No trace of him.
How does someone disappear on one of the most traveled trails in the US?
What happened to David O’Sullivan? And where is he now?
Listen as we dive into the Pacific Crest Trail, the case of David O'Sullivan, and how to stay alive on vacation.
