RedactedNarrative: Witnesses report that Vessel 1 Operator/Victim was anchored off of the point for several hours on Otter Lake. Witness reported that he drifted past the boat several times while drift fishing and observed Operator/Victim as the only person on board the boat for several hours.  Witness reported that he did not hear cries for help or the splash of Victim hitting the water.  Witness reports that he was one of the first people on scene and observed Victim in the water floating next to the boat that was now adrift with the anchor sitting on the boat's bow.  
  
  Witness reports that he last saw Victim standing in the boat approximately 15 minutes before the time of incident.  LE Supervisor informed Investigator that the boat engine was off and the boat was in neutral upon inspection.  Pending autopsy results for additional information. At this time details for most of the incident are unknown. Chippewa County SO drove the boat back to the other boat landing where the truck and trailer were stored.
  
  Final report is the same as the initial report with one main update to the cause of death.  Chippewa County Coroner reports death was due to freshwater drowning.  There may have been a fainting issue due to less than perfect blood flow in Victim’s heart from a defective heart valve.  Circumstances of how the Victim ended up in the waters of Otter Lake remain unknown.
