RedactedNarrative: On 07/14/2018 i, indiana conservation officer was patrolling lake shafer in a marked patrol boat and in boating class c uniform.  At 8:57 pm, white county dispatch advised me over the radio there was a boat incident with injury toward the area of buffalo bridge north of the sandbar.  I was at the north end of the dredge zone and activated the emergency lights.  There was very little boat traffic and i arrived on scene within minutes of the 911 call.
  I was waved over to a boat that was beached on the east side of lake shafer.  I observed a male on the back of the boat and he told me there was an accident and there was 2 victims inside the boat.  A female  walked around the back of their motorboat and held onto my patrol boat.  I asked subject1 how many victims were injured and she told me only 2.  A person in the motorboat asked me for my medical bag so i gave them my medical bag with limited supplies in it.  I asked subject1 what had happened and she told me the driver of the boat ward struck a tree branch and was knocked out, she grabbed the steering wheel because she was the sitting next to him in the passenger seat and turned towards shore and put the throttle in the neutral position and ended up on the shore of the east side of the lake where the boat was at when i arrived.
  First responders from buffalo vfd arrived on the other side of the river and i transported 3 of them to the boat with the victims in it.  The first of 3 ambulances arrived and i was getting ready to transport the medics and backboards to the boat when subject2 operated the boat with the victims and medical personnel to the other side where the ambulance was parked.  Monticello fire department arrived on scene and started to take care of the 2 victims that were in the boat.  I separated the passengers to get their names and information when cpl arrived on scene and assisted getting statements and the information from all of them.  The two victims that had the most injuries (operator and subject3) were transported to white county memorial hospital and eventually taken to methodist hospital in indianapolis by helicopter.  A third person also went to white county memorial because he said that he was knocked unconscious but was released later that night.
  After all the passenger names and information was obtained, ico received permission in writing from subject2 the boat owner to release the boat to the idnr law enforcement to complete the incident investigation.  Ico transported subject2 and another passenger to get the trailer for the boat.
  Cpl and i took pictures of the initial impact tree and the final spot where the boat was at when i arrived on the other side of the river.  We secured the boat in a side-tow and i towed the boat to the ramp downstream from the sandbar restaurant where it was loaded onto the trailer.  Ico transported the boat and trailer to prophetstown state park and placed inside a locked facility.  
  On 7/15/18, i went back to the accident scene and took measurements from the initial impact to where the boat was located on the other side of the river which was 277 yards.  The measurement from the shore to the initial impact area was 7 feet from shore.  
  On 7/16/18, i secured a search warrant to remove any and all electronic information from the motorboat to assist in the boating incident investigation.  Cpl assisted me in searching the boat and logged information about the contents of the boat.  There was 3 wearable life jackets on board and a throwable cushion.  All the beer cans were counted and there was 41 (miller high life, miller lite and coors light) empty beer cans and 3 full beer cans all over the bottom of the boat.  The docking light switch was in the forward position as well as the accessory light switch.  Both fill bags in the rear of the boat were empty and the hour reading on the boat was 110.9.  I took more pictures of the inside and outside of the boat from different angles.
  On 7/17/18, i transported the mondo moomba to mid-indiana marina and requested them to remove information from the motor and he advised that he was only able to get the last codes of the motor which would not be pertinent to the investigation.  I transported the boat back to prophetstown state park and placed it back inside the locked facility.  
  On 7/18/18, isp detectives came to prophetstown state park and performed a 3d scan of the boat and took more pictures of inside and outside of the boat.
  On 7/20/18, i met with subjects and received written statements from them about what had happened prior to and during the accident which are attached to this report.  I stopped and met with subject3 and asked him about the accident and he stated he couldn't remember anything about what had happened.
  On 7/21/18, i performed a function check on land of the throttle cable and steering of the mondo moomba and both functioned correctly.  I transported the boat per request of subject2.  I was not able to place the boat and trailer into the barn because of the damage to the ski rack placed it outside in front of the barn and advised subject2 where it was.
  On 8/13/18, i received the requested medical paperwork from the white county prosecutors' office.  This information was subpoenaed by the prosecutors' office from methodist hospital for operator, the operator.  I observed the reading of .207 from the lab results performed on 7/14/18 at 22:57.  I also observed that there was a positive result of benzodiazepines in the drugs of abuse urine screen.
