Both were aboard the Sapphire Princess on a cruise that originated in Sydney, Australia.

According to a Honolulu police report, Clark died Sunday and Letkeman yesterday.

Clark was experiencing health problems on the cruise and had gone to the infirmary for medical attention, police said. On Sunday, she began experiencing breathing difficulties.

Letkeman had fallen a couple times during the cruise, police said, and complained of dizziness while in the bathroom yesterday. He lost his balance while in the bathroom and fell.

The medical examiner's office plans an examination tomorrow to determine cause and manner of death.

Police have tentatively classified the cases as unattended deaths. There was no evidence of foul play, police said.
