Clifford Culloden, a 59-year-old man from California, traveled to Kauai and arrived on January 16, 2006, reportedly for a temporary stay. He is described as a white male, 5 feet 9 inches, about 150 pounds, with white hair, blue eyes, a short beard and mustache, and a receding hairline.

Culloden remained in some contact with family for a few months, but the last known contact came in April 2006 when he mailed a package and a letter to his wife that implied he was feeling suicidal. After that communication, all contact stopped and he has not been seen or heard from. The Kauai Police Department lists him as an endangered missing person; few details about his whereabouts after the April letter have emerged.

Does anyone on Kauai or who knew Clifford in 2006 have information about his stay or where he might have gone after April?
