Story summary

On October 21, 2026, 70-year-old David Arai was found safe after more than 24 hours of searching by police and National Park personnel in Hawaii Volcanoes National Park. Arai had been reported missing around 12:16 p.m. on Monday, October 19, with his empty rental car discovered inside the park later during the search. A three-year-old Labrador named Trina located him at about 7:30 p.m., two miles from where his vehicle was found.

Arai is now considering adopting Trina after her successful rescue mission.
