He was not accounted for when a commercial tour group dive ended Monday in the Waialae-Kahala area. The group had been diving at a sunken wreck called “Baby Barge.”

While the Coast Guard has called off its search, Honolulu firefighters kept searching Wednesday from the air and underwater for the missing diver.

Firefighters are also walking along the coastline because the strong swell could have pushed Curley to shore.
