The Honolulu medical examiner’s office on Sunday identified a 55-year-old swimmer who died this weekend after being pulled from the ocean at Malaekahana State Recreation Area as Ben Fung of Honolulu.

An autopsy will be done tomorrow.

Police said Fung had been swimming when he became unresponsive at about 2:15 p.m. Saturday. A good Samaritan found Fung in choppy water with 2- to 3-foot waves and brought him to shore, an Emergency Medical Services report said. Lifeguards and firefighters performed CPR until paramedics arrived and took over treatment.

Police said Fung was taken to a hospital where he died. An unattended death case has been opened.
