At about noon, a lifeguard spotted a woman face down and not moving about 75 yards offshore, said Jim Howe, chief of operations for the city's Ocean Safety Division. She was brought to shore but did not have a pulse and was not breathing, Howe said.

The lifeguard was able to resuscitate the woman, identified as a 72-year-old visitor from Japan at Hanauma Bay with her husband. She was taken to Straub Hospital, where a spokeswoman said she has been cleared for release today.

While emergency crews were working on the woman, someone ran to them and said lifeguards had found an unconscious 52-year-old man from Washington about 200 yards down the beach.

Howe said another visitor identified as a physician was attempting to revive the man, described as "completely unresponsive." He was taken to The Queen's Medical Center in critical condition and later died. Medical examiners had not identified him this morning.

Howe said it was not known whether the man ran into trouble in the water or if he had collapsed on shore. He said the area where the man was found is not known for swimming or snorkeling.
