A man found Sunday in the Yellowstone River by rescue crews was pronounced dead at a Billings hospital that day, according to Yellowstone County Coroner Cliff Mahoney. The Billings Fire Department and Yellowstone County Sheriff's Office had worked together to get the man out of the water where he was found unconscious sometime after they were called for a rescue at about 8:13 a.m. The rescue took place along an area of the river about a mile down Old Blue Creek Road. Officials were still gathering information Sunday after the rescue. It appeared that prior to the rescue the man and a child were fishing in a boat when a medical emergency occurred, Cpl. Adam Lauwers of the sheriff's office said Sunday. When responders arrived the juvenile was in a passerby's car, Battalion Chief Kevin Johnson said Sunday. Johnson said that CPR was performed on the man found in the water and that he was given to American Medical Response. He was taken by ambulance to an area hospital.
