RedactedNarrative: On August 1, 2014 at 1920 hours I was called to the scene of a jet ski accident at El Dorado Reservoir by Butler County Dispatch. I arrived at the scene which was by Bluestem area 4 campground at 1957 hours to talk with officers about what happened. They explained one person V2 was on the way to the hospital and the other V1 was in the campground area. I observed the vessels and noted heavy damage on the front of V2 and a small area of damage on the front of V1. I found from talking with the officers that V2 had sustained the damage on the right side of his body. I talked with V1 about what happened and V1 explained he was following V2 on the lake when V2 turned in front of him and he didn''t have enough time to avoid striking the vessel. I collected the vessel information and told them I would talk with him later. On August 2, 2014 I made contact with subject who owned the PWCs and whose son was involved. I found out the extent of the injuries that his son had. I inquired around the campgrounds if anyone witnessed the accident and one man stated he saw it occur. I asked subject2 to explain what he saw and he described V2 driving on the left side of V1. Subject2 stated V1 started turning to the right and "just ran over" V2. I asked if Subject2 knew either of the riders and Subject2 stated he didn''t and he just happened to be looking at the water when it happened. 
  On August 8, 2014 I spoke with V2 about what happened from his point of view. V2 said they both took off at the same time with V2 ahead of V1. V2 said he noticed V1 jumping his wake so he stopped so he could talk with V1 about it. V2 stated he was almost stationary and had turned to the right when he saw V1 coming at him. V2 stated he didn''t have time to do anything but brace for impact. 
  After reviewing all the information and damage, I have filed a charge of negligent operation against V1 with the county attorney in Butler county.
