RedactedNarrative: Operator was known to fish for catfish at night. He left his residence on 09/24/2020 at approximately 15:30 hours. A passerby called 911 reporting a male slumped over the steering wheel of his boat on Lake Ninevah at approximately 0700 hours on 09/25/2020. Emergency responders responded and located his drifting boat with the operator submerged in the water, yet still hanging on to the side of his boat. The operator was deceased. The accident was unwitnessed, however it is believed he entered the water wearing hip waders, was unable to get back into his boat and died as a result of cold water submersion/drowning. The operator was not a good swimmer and would not likely have entered the water wearing hip waders voluntarily. Therefore it is believed that he slipped and fell into the water, hung onto the side of the boat where he dies as a result of cold water immersion/drowning.
