Noah Pomaikai Montemayor was 16 when he disappeared from his Hawaii Kai home on the night of September 29, 2015. His parents last saw him go to bed; sometime during the night he packed a bag, slipped out a bedroom window, and left the house. At first thought to be a runaway, he was soon classified as an endangered missing person after information suggested he may have been emotionally distressed.

Noah was a student at Punahou School, active in junior ROTC, cross-country and the school symphony. His backpack was later found abandoned on the Makapu u Lighthouse Trail; it contained his cellphone, a charger, sunscreen and flashlights. Island-wide searches, including Coast Guard searches of surrounding waters and ground parties on difficult terrain, produced no confirmed trace. A secret file on his computer, found by his mother, contained writings expressing loneliness and despair, which deepened concerns for his welfare. A few potential sightings were reported but none were verified.

The circumstances — leaving at night, possessions left at a coastal trailhead and troubling personal writings — leave the case unresolved. Does anyone who knew Noah or was on the Makapu u Lighthouse Trail that night have information to share?
