RedactedNarrative: A witness at a home on Windigo Lake observed a small fishing boat making circles under power on Windigo Lake.  The witness thought he saw a person in the water, so he and his wife took their pontoon boat out to the unoccupied boat.  
  They found the male victim in the water approximately 15 yards from the boat.  He was unresponsive.  The witness jumped into the water and held the man up as the witness's wife towed them both to shore with the pontoon.
  First responders did find weak vital signs but were unable to revive the victim.  There were no signs of injury on the victim's body. The victim was found to have a history of heart disease, and had an implanted pacemaker.
  The boat was found with the tiller turned all the way for a starboard turn.  A clamp-on boat seat was found dislodged from the metal bench seat and tipped back on top of a gas tank located at the stern of the boat.  There was a wooden dowel for a small flag attached to the starboard stern of the boat.  This dowel was broken off toward the outside of the boat.  Based on the position of the seat and the broken dowel, it appeared as though the victim had fallen from the boat at the starboard stern.
  
  Coroner felt the death was natural causes and no autopsy was performed.
