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.
