From Hawaii Police Department:
A Canadian man apparently drowned Wednesday morning (April 11) in waters off Kailua-Kona.
The victim has been identified as 49-year-old William Savage of Okotoks in the Canadian province of Alberta.
At 11:20 a.m., Kona patrol officers responded to Kona Community Hospital, where they learned that Savage had been part of a scuba diving tour in waters north of Honokohau.
A large surge reportedly knocked him off some rocks and into the water. When he failed to surface, tour members pulled him onto the boat, began CPR and took him to Honokohau Harbor. From there, fire/rescue personnel took him to the hospital, where he was pronounced dead at 10:23 a.m.
An autopsy has been ordered to determine the exact cause of death.
