A 46-year-old Kahului man who apparently was trying to pick opihi was found floating face down in waters off of Hana Thursday, Maui firefighters said.

The man was last seen around 11 a.m. Thursday and was overheard saying that he was going to pick opihi, firefighters said. A tourist who later saw the man yelling and waving his arms ran to the nearest home to call for help.

Ten minutes later the victim was found floating face down, firefighters said.

Emergency responders arrived at 1:51 p.m. and found the man floating face down about 50 feet from shore. The Maui Fire Department’s Air-1 helicopter brought the man to Nahiku Landing at 2:30 p.m. where he was pronounced dead at the scene.
