Officials have located the body of a 17-year-old boy who was reported as missing Saturday in the waters off Sand Island.

First responders on Saturday searched for a boater who went missing at around 11:30 a.m., the Honolulu Fire Department said. A male, described as being 17 or 18 years old, may have fallen off a moving, 21-foot boat near 4 Sand Island Access Road, the Honolulu Emergency Services Department said in a news release.

The teenager didn’t surface, and others on the boat could not find him, the fire department said.

HFD, Honolulu Ocean Safety, the state Department of Transportation and the U.S. Coast Guard coordinated a search for the 17-year-old via air and water. At around noon, HFD divers began searching underwater because of low-visibility conditions.

At around 4:15 p.m. the teenager was found unresponsive and brought to shore, where Honolulu Emergency Medical Services personnel pronounced his death. His identity was not immediately released.
