Authorities say a 63-year-old man has died while boating at Lake Red Rock in southern Iowa.
The Marion County Sheriff's Office says emergency personnel were sent to Whitebreast Bay at the lake around 3 p.m. Sunday. They met other boaters who had stopped to help the man and his wife.
The Sheriff's Office says Michael Nicholson likely had a heart attack that caused him to capsize the boat. His wife held onto his body until the other boaters arrived. Nicholson, of Bondurant, was pronounced dead at the scene.
