The search for Daylenn Pua is continuing Thursday, exactly one week since he failed to return from a hike, seemingly swallowed up by the Koolau mountains.

On Wednesday, a Navy helicopter, three drone operators, about a dozen spotters and roughly 20 to 30 hikers, including strangers who were moved to help the family of the Kona man, searched in the mountains between Haiku and Moanalua.

Meanwhile, family members on Hawaii island remotely pored over the high-resolution photos taken by a drone operator to see if they could spot some sign of the missing 18-year-old.

Others brought food, including plate lunches, poke and pizza, and drinks for the family and volunteers.

The Honolulu Fire Department concluded a four-day search for Pua, which included the use of a helicopter and rescue personnel, at 2 p.m. Tuesday.
