A 70-year-old Canadian man apparently drowned Wednesday at Kahaluu Beach Park near Kailua-Kona.

Authorities identified the victim as Ian Michael Gordon of Alberta, Canada.

Kona police said a witness saw the man snorkeling at 3:40 p.m. when he became motionless about 40 feet from shore. A lifeguard brought the man ashore and began cardiopulmonary resuscitation. The victim was taken to Kona Community Hospital, where he was pronounced dead at 4:13 p.m.

An autopsy will be conducted to determine the cause of death.
