RedactedNarrative: VESSEL 1 WAS LEAVING EUFAULA COVE AFTER FILLING UP AT THE GAS DOCK AT EUFAULA COVE. VESSEL 1 HAD TRAVELED APPROXIMATELY 400 YARDS NORTHEAST  AND WAS STILL IN THE NO WAKE ZONE WHEN FOR UNKNOWN REASON IT EXPLODED. AFTER THE VESSEL EXPLODED, IT CAUGHT FIRE, BOTH THE OPERATOR AND PASSENGER JUMPED OUT OF THE VESSEL AND SWAM AWAY FROM THE VESSEL. WITNESS 1 WHO WORKS WITH TOW BOAT U.S. WAS NEAR BY AND DROVE TO BOTH OF THE INDIVIDUALS IN THE WATER AND PLACED THEM IN HIS BOAT. I ARRIVED MINTUES LATER AND TOLD WITNESS 1 TO DRIVE TO THE FRONT OF THE MARINA, BECAUSE I HAD ALREADY CALLED FOR A AMBULANCE. ONCE AT THE FRONT OF THE MARINA, FIRST AID WAS GIVEN TO PASSENGER 1 UNTIL THE AMBULANCE ARRIVED. PASSENGER 1 WAS LIFE FLIGHTED TO HILLCREST BURN CENTER IN TULSA. THE OPERATOR REFUSED TREATMENT AT THE SCENE. THE LOCATION OF THE EXPLOSION WAS APPROXIMATLEY 185 YARDS SOUTH OF THE SOUTH END OF THE ROCK JETTY AT EUFAULA COVE AND APPROXIMATLEY 606 YARDS EAST OF THE PRIVATE BOAT RAMP AT EUFAULA COVE AND 283 YARDS NORTH OF THE NORTH EDGE OF COUNTY ROAD SEQUYAH DRIVE IN EUFAULA. THE VESSEL BURNED TO THE WATER LEVEL AND SANK. CAUSE OF EXPLOSION IS UNABLE TO BE DETERMINED DUE TO THE BURNED REMANANTS OF VESSEL SINKING.
