The U.S. Coast Guard joined the search for a 44-year-old diver who vanished in the waters off Hawaii’s island of Kauai. 

Bryson Higashi was last seen around 4:30 p.m. local time Tuesday near Hanalei, a town on the island’s northern coastline, according to the Coast Guard. 

“Coast Guard Sector Honolulu command center watchstanders received a notification at 7:36 p.m. Wednesday from Kauai Fire Department personnel of a possible person in the water near Hanalei Bay,” the agency said. 

“Watchstanders issued an urgent marine information broadcast and coordinated the diversion of a Coast Guard Station Kauai 45-foot Response Boat-Medium crew, an MH-65 Dolphin helicopter crew and an HC-130 Hercules airplane crew from Coast Guard Air Station Barbers Point,” it added. “The Coast Guard Cutter William Hart (WPC 1134) crew also diverted for the search.”
