Man’s puzzling disappearance in national park triggers frantic 24-hour search involving K-9

A 70-year-old man was found after spending more than 24 hours missing in Hawaii Volcanoes National Park. The search involved police, park staff, a helicopter and a specially trained dog, and ended with the man receiving medical care for dehydration and exposure.

David Arai was last seen in the Volcano area on 19 October, and police reported him missing at about 12.16 pm. His rental car was found in the park; at about 7.30 pm, K-9 Trina located him on a trail roughly two miles away. Arai’s son said he knew the area’s trails and often hiked alone. Trina, a three-year-old Labrador, had also helped find an endangered teenager the previous month.
