Authorities ID man who died after Wisconsin Half Ironman triathlon

MADISON — Authorities say a Wisconsin man apparently accidentally drowned during the swimming portion of the Half Ironman 70.3 triathlon in Lake Monona.

The Dane County medical examiner's office on Monday identified the man as 61-year-old Michael McCulloch of Cottage Grove.

The medical examiner's office says preliminary autopsy results confirm that McCulloch's death "was consistent with an accidental drowning due in part to a medical event." Additional tests are underway.

McCulloch was taken out of the water Sunday. He was pronounced dead at a hospital. His death remains under investigation.

A second man also was taken out of the water about an hour later and was taken to a hospital in critical condition. Madison Fire Department spokeswoman Cynthia Schuster says he remained in the hospital Monday.
