RedactedNarrative: Family group was going for a pontoon ride. The operator pushed away from the dock and tried to start the motor. There was a mechanical issue and he could not get it started. He jumped in the water to bring the boat back to shore. He started to struggle, and others from the boat attempted to assist him, but were unsuccessful. After a 911 call was placed, they got him back to shore with the aid of an innertube. The rescue squad arrived and started CPR. CPR continued, although the victim was unresponsive. Life jackets were on board, but were only used by the two children (8 years and 5 years old) on board. A Type IV throwable was readily available on the floor of the boat, but was not used. A wind was blowing out (NW) causing the boat to drift (along with victim) out from shore. The boat was retrieved by a third party on the opposite side of the lake, with three people still on board.
