RedactedNarrative: On 4/4/18 at approximately 0845 hours, a single vessel accident occurred on Trout Lake, in Osceola County Florida.  An open motorboat occupied by two adults, one male (69 years old) and one female (71 years old), was engaged in cruising activities while under power, when the female occupant fell overboard for reasons yet undetermined.  After falling overboard, the victim was struck by the motor and her clothing became entangled in the propeller.  The male operator jumped into the water and attempted to free the victim but was unsuccessful.  A nearby good Samaritan heard the calls for help and assisted the operator to free the victim enough to keep her head above water while transiting to shore.  The unconscious victim was transported to the Osceola Regional Medical Center where she later died. This investigation is ongoing and information may change due to new details. "Other" used as "Unknown" for the contributor at this time. The victim fell overboard while underway and was run over by the vessel.  She was struck by the prop and her clothes became entangled.  She suffered trauma to the back from the prop strike and was held under water.
