The Honolulu Medical Examiner’s Office has identified a man whose body was found just before noon Sunday in the Hilton Hawaiian Village lagoon as Eduardo Gabriel, 50, of Los Angeles.

The cause of death was deferred Monday pending further investigation including toxicology and microscopic testing, which could take up to eight weeks.

Deputy Medical Examiner Masahiko Kobayashi said there were conflicting reports on what Gabriel had been doing, possibly paddleboarding or snorkeling, but he had waved his hands for help.

Police said the man had been snorkeling with his family.

He was taken in critical condition to Straub Medical Center, where he later died.
