RedactedNarrative: ON MAY 22, 2021, AT OR ABOUT 7:31 P.M., I, INDIANA CONSERVATION OFFICER 1, WAS NOTIFIED BY SULLIVAN COUNTY DISPATCH THAT THEY HAD RECEIVED REPORTS OF A WOMAN SUFFERING A HEAD INJURY BECAUSE OF A BOATING ACCIDENT. I ARRIVED AT THE MAIN BOAT RAMP OF SULLIVAN LAKE AND LOCATED THE INDIVIDUALS INVOLVED. SULLIVAN COUNTY AMBULANCE TEAM, SCAT 1, BEGAN TREATING THE FEMALE, INJURED, WHO ALLEGEDLY LOST CONSCIOUSNESS AFTER BEING THROWN FROM AN INNER TUBE THAT SHE AND HER BROTHER, BRETT MATHENA, WERE RIDING.    
      WHILE INJURED WAS BEING EVALUATED BY SCAT 1, I BEGAN INTERVIEWING AND COLLECTING INFORMATION FROM THE WITNESSES ON THE BOAT. OPERATOR WAS THE OWNER AND OPERATOR OF THE BOAT. OPERATOR STATED THAT HE WAS PULLING THE TUBE APPROXIMATELY 15-20 MILES PER HOUR, AND AS HE TURNED THE BOAT AT THE NORTH END OF THE LAKE, THE INNER TUBE CROSSED THE WAKE AND THREW THE OCCUPANTS OFF IT. OPERATOR STATED THAT HE DID NOT BELIEVE THAT HE STRUCK ANYTHING IN THE WATER WHICH COULD HAVE CONTRIBUTED TO THE INCIDENT. OPERATOR INFORMED ME THAT HE HAD NOT BEEN DRINKING, AND I DID NOT DETECT ANY SIGNS OF IMPAIRMENT WHILE SPEAKING WITH HIM. I INSPECTED AND PHOTOGRAPHED THE BOAT AND INNER TUBE THAT WAS PULLED DURING THE INCIDENT.   
      WITNESS WHO WAS ONE OF THE OBSERVERS ON THE BOAT, INFORMED ME THAT HE HAD BEEN RECORDING THE INCIDENT AND PROVIDED ME WITH A COPY OF IT. WITNESS'S VIDEO WAS CONSISTENT WITH THE INFORMATION BEING PROVIDED BY THE PASSENGERS OF THE BOAT. THE VIDEO DETAILS INDICATE THAT THE INCIDENT OCCURRED AT 6:37 P.M.  
       TUBER 2, WHO WAS ON THE INNER TUBE WITH INJURED, STATED THAT HE DID NOT KNOW WHAT SHE HIT HER HEAD ON. TUBER 2 STATED THAT HE SWAM UP TO HIS SISTER AFTER THE INCIDENT, WHO WAS FLOATING ON HER BACK, AND HE SAID SHE APPEARED TO BE OUT OF IT. HE WAS NOT SURE IF SHE LOST CONSCIOUSNESS, BUT SHE APPEARED DAZED AND SOMEWHAT INCOHERENT. BOTH TUBER 2 AND INJURED WERE WEARING PERSONAL FLOTATION DEVICES WHEN THE INCIDENT OCCURRED.    
      INJURED'S HUSBAND, PASSENGER 2, WAS A PASSENGER ON THE BOAT AS WELL. PASSENGER 2 STATED THAT HIS WIFE HAD CONSUMED TWO OR THREE SMIRNOFF RED WHITE AND BLUE ALCOHOLIC BEVERAGES PRIOR TO THE INCIDENT OCCURRING. I INFORMED HIM THAT I WOULD FOLLOW UP WITH HIM AND HIS WIFE AT SULLIVAN COUNTY COMMUNITY HOSPITAL LATER THAT EVENING.    
       I FOLLOWED UP WITH THE INJURED'S FAMILY AT SULLIVAN COUNTY COMMUNITY HOSPITAL. I WAS INFORMED BY MEDICAL PERSONNEL THAT THERE WERE NO DOCUMENTED INJURIES ON HER CT SCAN OR EVALUATION. INJURED WAS TREATED FOR A CONCUSSION AND WOULD LIKELY BE RELEASED THAT EVENING.
