Sean Ryan, 23, disappeared from the Big Island of Hawaii after a visit to friends in the Fern Acres subdivision in upper Puna. He was last seen on August 12, 2007, at a friend’s residence. At the time he was not wearing a shirt and was reported to be in either white shorts or blue flannel pajama bottoms; he normally wore eyeglasses but did not have them when last seen. He is 5 feet 10 inches and about 160 pounds with short, curly blond hair.

Ryan had been living on Oahu for four years and had previously spent a year in the Kona area. He was in the process of moving to Colorado when he went to Puna. He reportedly had a medical condition requiring medication that he had recently stopped taking, and was experiencing paranoia, delusions and hallucinations. Investigators and family have raised the possibility he became lost or was avoiding contact; suggestions mentioned he might have gone toward Drum Circle Beach, Volcano, or back to Kona. No confirmed sightings or contact have been reported.

Does anyone who knew Sean or who was in Puna on or after August 12, 2007 remember seeing someone matching his description?
