A swimmer who died Monday while participating in the annual Waikiki Roughwater Swim has been identified by the Honolulu Medical Examiner as 48-year-old Daniel Mindich, an English instructor and director of the summer school at Punahou. He ran into trouble halfway through the race. It was the first death for that annual Labor Day race. Mindich was pulled unresponsive from the water at Kaimana Beach just before 10 a.m. and transported in critical condition to a hospital, where he later died. Event organizers say safety is paramount. They hired 15 lifeguards and about 60 water safety volunteers to closely monitor swimmers during the race. Nearly 1,000 swimmers participated in this year's event. The 2.4 mile ocean swimming race starts at the New Otani Kaimana Beach Hotel and ends at the Hilton Hawaiian Village.
