RedactedNarrative: On 7/20/14 at approximately 1333 I responded to a call from ISP District 21 regarding a boat accident on the Kankakee River involving a skier who sustained personal injury. I arrived on scene at Beckman harbor at approximately 1345 shortly after Kankakee EMS transported the skier to St Mary''s hospital. CPO went directly to St. Mary''s hospital to gather information from Victim. The operator of the ski boat (IL 7742 KL) was Operator1 and her son V1 lookout was acting as the observer watching his uncle Victim slalom skiing. 
   
  The operator of the fishing boat was Operator2 and his wife and step-daughter were seated directly next to him facing the bow. Both the ski boat and the fishing boat were traveling eastbound on the Kankakee River towards the I-57 bridge. The fishing boat was nearest to the south bank of the river and was being overtaken by the ski boat on the port side. The ski boat had one skier (Victim) in tow and was travelling at 33 mph according to a statement made by Victim to CPO while at the hospital. The fishing boat was travelling at an estimated 30 mph according to Operator2. Operator2 stated that he believed his speed to be around 30 mph which was just enough to keep his boat on plane. 
   
  According to Operator2 and the occupants on his boat, the ski boat was overtaking them on their left side and was making turns to the left and to the right while maintaining a general eastbound heading. Operator2 said he saw the ski boat make a left turn heading towards the center of the Kankakee River as both boats were approaching the danger buoys on the west side of the I-57 bridge. Operator2 said he maintained his speed and course as he was being overtaken by the ski boat. Operator2 stated that the ski boat after making the left turn towards the center of the river made a right hand turn followed by a left hand turn placing the ski boat in front of the fishing boat. 
   
  According to Operator2, on the last left hand turn made by the ski boat the skier jumped the wake behind the ski boat and collided with the port side bow of his fishing boat. Operator2 said when he saw the skier cutting across the wake towards him he immediately pulled the lanyard kill switch to his motor. Operator2 and the occupants on his boat said the skier (Victim) impacted the boat and landed on the fishing platform towards the bow. Operator2''s step-daughter and wife immediately attended to Victim on the front of the boat according to statements. Operator2’s wife and step-daughter both said it was apparent Victim had broken his leg and they told him to lie still and continued talking to him to keep him calm. Operator2 said he transported Victim back to Beckman harbor while one of the occupants of the ski boat called 911. The ski boat followed the fishing boat to Beckman harbor where paramedics arrived to transport Victim. Victim was admitted to St. Mary''s where he was being treated for a broken femur. 
   
  Due to Victim''s condition and being administered morphine at the hospital CPO was unable to conduct a full interview with him. A more thorough interview will be conducted when Victim''s recovery allows. Both Operator1 and her son V1 lookout provided verbal and written statements (attached) as well. V1 lookout''s statement differed slightly from other witness accounts. In V1 lookout’s written statement he said that when the ski boat he was on passed the fishing boat that the fishing boat was not moving. I asked Operator2 if he was sitting still in the water and he informed me he had maintained his speed and course up until the point right before impact when he pulled his lanyard kill switch.
