RedactedNarrative: Agent was notified of a boating accident involving one boat with two passengers. Agent was also informed that there was one injured passenger that was being transported to the hospital. Agent responded to the scene, while Sergeant assisted by responding to the hospital (where both involved subjects were). Upon further investigation, Operator (age 12) was found to be the driver of the vessel. Operator was asked by his grandfather, Grandfather, to drive the boat while he took the drain plug out to show him how to drain a boat on water while underway. After Grandfather pulled the plug he told Operator to make a sharp right turn, upon doing so grandfather lost his balance and fell from the vessel on the starboard stern side. Operator turned the boat around and attempted to aid his grandfather who was having trouble staying afloat in the water (not wearing a PFD). While trying to aid his grandfather, Grandfather told him to leave him and go get help. Operator left the subject in the water and rode back to a row of camps on the canal to get help from other family members, as well as other bystanders. Grandfather was pulled from the water and CPR was started immediately, upon obtaining a weak pulse he was transported to the hospital. While at hospital, Grandfather passed away. Cause of death was determined to be heart attack. There was no damage to the vessel.
