Matthew Curley, a 28-year-old doctor from New York City, vanished during a scuba dive off Oahu on August 29, 2011. He entered the water with a commercial tour group at the Baby Barge wreck site, a half-mile off Waialae-Kahala, where dives reach 60 to 80 feet. Curley was certified and trained; he was last seen entering the water wearing a black diving suit and did not surface with the rest of the group.

An immediate multi-agency search followed. The U.S. Coast Guard and Honolulu Fire Department conducted aerial, surface and underwater searches, while teams walked the shoreline because of strong swells. A scuba fin found in the water was identified as the same type and size Matthew had been using. After days of searching with no further trace, the Coast Guard suspended active search efforts; Honolulu firefighters continued for a time.

The disappearance remains unresolved. Did anyone on that dive or in the Waialae-Kahala area that week see Matthew or notice anything unusual that day?
