After missing for over a day in Hawaii Volcanoes National Park, 70-year-old David Arai was successfully located by Trina, a skilled police dog, who led the search team through dense foliage. Found two miles from his rental car and suffering from dehydration, Arai expressed immense gratitude to his rescuers and is now contemplating adopting Trina, who has proven her tracking abilities with two recent rescues.
