A 34-year-old woman is dead after becoming unresponsive in waters 100 yards off Makua Beach Wednesday morning.

Lifeguards responded by paddleboard and rescue watercraft and boarded the tour boat the patient was with.

Boat staff and lifeguards performed cardio pulmonary resuscitation (CPR) on the vessel, then lifeguards brought the patient to shore at Makua Beach where CPR continued.

She died at the hospital about two hours later.

It is unknown at this time what type of snorkel the woman was using.
