Justin Shetler, 35, an American survivalist and travel blogger from Oregon, vanished in the Parvati Valley of the Indian Himalayas after setting out on a spiritual pilgrimage in late August 2016. He was last seen on September 3, 2016, by other hikers returning from the trek; they said he had separated from the sadhu who accompanied him and hadn’t eaten in a couple of days but seemed determined to press on.

Indian authorities located and arrested the sadhu; the man reportedly said Shetler walked on ahead and that he lost sight of him after dark. The sadhu died by suicide while in police custody before providing substantive information. Extensive searches turned up no trace of Shetler; his motorcycle and the belongings he had left behind before the trek remained untouched.

The circumstances — the final blog message, the sadhu’s death, and the lack of physical evidence — leave major questions about what happened. If anyone had contact with Justin in or around the Parvati Valley in August or September 2016, or saw him on the trail on September 3, please come forward with information.
