In the summer of 2015, 20-year-old Tristan Postadan was reported missing from the Captain Cook area on the Big Island of Hawaii after he stopped making contact with family. Tristan is described as a Caucasian male, 6 feet 2 inches, about 180 pounds, with brown hair and brown eyes. The last known location associated with him was the Kaawaloa Trailhead, where his 1998 white Toyota Camry was found parked and abandoned.

Hawaii Police and Fire Departments conducted an extensive search of the trail and the rugged coastline down to the ocean but found no sign of Tristan. The department issued a public appeal for information about anyone who saw him or his vehicle around the time he disappeared. No further details about his movements after his car was found are provided.

Does anyone have information about Tristan, his vehicle, or sightings in the Captain Cook area that summer?
