The medical examiner identified a 44-year-old man who died Sunday while participating  in the Windward Oahu biathlon at Kailua Beach as a Navy officer and husband of the commander of the Pearl Harbor-based destroyer USS Halsey.

Lt. Cmdr. Erik Sweet drowned while participating in the Kailua Dash & Splash Biathlon with his wife Cmdr. Linda Seymour, a Pearl Harbor spokesman said. 

Sweet was found unresponsive when he was brought to shore at 7:45 a.m.

Emergency Medical Services took Sweet to a hospital, where he later died.

A police report said there are no signs of foul play. 

The medical examiner classified the case as an accidental drowning.

The Navy said Sweet was assigned to the Naval Shipyard in Bremerton, Wash. and was visiting with his wife. He listed his home as Port Orchard, Wash. He was planning to retire from the Navy this month.

 The Kailua Dash & Splash Biathlon is a 2.8-mile run around Lanikai Loop and an 800-meter swim through Kailua Beach which ends at Kalapawai.

 Seymour relieved Cmdr. Gary L. Cave as commanding officer of the destroyer USS Halsey on April 18, 2014.
