Hawaii island firefighters resumed searching today for a male who went missing Saturday in a pond above Rainbow Falls along Wailuku River in Hilo.

Firefighters responded to the incident about 12:40 p.m. Saturday after witnesses reported a male and a female having difficulty swimming in a pond above the falls. Witnesses saw the two go underwater and not resurface, Big Island firefighters said.

Firefighters found the female unconscious in the water below the falls. She was taken by helicopter to an awaiting medical unit that took her to Hilo Medical Center while performing CPR. Police said she later died. Her identity was not immediately released.

Firefighters searched underwater and from the air and ground for the male in the pond and downstream areas. They suspended their search at nightfall and planned to resume searching this morning.

Police said the search was still ongoing this afternoon.
