RedactedNarrative: On the evening of July 2, 2016 I, Ranger First Class (Rfc.) with the Georgia Department of Natural Resources Critical Incident Reconstruction Team (CIRT), was notified by Lieutenant (Lt.) (CIRT) of a boating incident involving a serious injury on Lake Lanier in Forsyth County.  I was contacted by Corporal (Cpl.) (CIRT) and she agreed to assist me with the case.  I then contacted Cpl. who initially responded to the incident.  Cpl. told me a man had suffered severe propeller cuts to his legs, and the man was likely have both legs amputated.  
  
  Cpl. told me the vessel was inventoried, and the vessel would be stored at the Aqua Land DNR facility in Hall County.  I was also informed the operator had been arrested by Rfc. for operating a vessel under the influence.  I contacted Cpl. and we agreed to meet the following morning at the Aqua Land facility.
  
  On July 3, 2016 Cpl. obtained a search warrant in Hall County for the vessel involved in the incident.  The vessel was an Ebbtide ski boat with registration GA 6680 SB, and hull identification number ETC00581B303.  When Cpl.1 arrived we read the witness statements that were obtained at the scene. 
  
  When we finished reading the statements, we pulled the vessel out of the storage building.  After pulling the vessel out, we measured and photographed the vessel.  I observed a large amount of blood on the transom of the vessel.  There were numerous alcoholic beverages located in the vessel including empty containers of beer, champagne, and rum.  Additionally, there was a nearly empty 1.75 liter bottle of Jameson Irish Whiskey in the vessel.  I located a metal drink container in the driver's cup holder containing a liquid with a very strong odor consistent to that of an alcoholic beverage.  I also located two sections of a blue ski rope that appeared to have been severed.  
  
  While examining the propeller, I noticed one of the blades had been damaged and bent at an approximate 90 degree angle.   Additionally, I noticed there were only three wearable personal flotation devices (pfds) and two type four throwable pfds.  Two of the pfds were for children, and one was for a small adult.  After photographing the vessel, one of the occupants of the vessel, Subject1 arrived to pick up a set of car keys from the vessel.  Cpl.1 and I interviewed Subject1 inside an office at the facility.  Subject1 said Victim had been wake boarding.  He said Victim was in the water near the motor, when the operator Operator apparently put the vessel in reverse.  Subject1 said they immediately pulled Victim from the water, but he had already been severely injured.  Subject1 said bystanders on a nearby dock assisted and they used a belt as a tourniquet.  After interviewing Subject1, Cpl.1 and I secured the vessel back inside the storage building and left Aqua Land. 
  
  On July 11, 2016 I returned the search warrant for the vessel to the Hall County Magistrate Court.
  
  On July 24, 2016 I obtained the incident report from Rfc. regarding Operator's arrest.  In Rfc. report it stated Operator did not submit to a full battery of field sobriety exercises.  In reference to not performing field sobriety exercises, Operator made the comment, "No, no I'm not doing fields, I'm smoked man".  According to Rfc. report, Operator submitted to a sample of his blood under Georgia Implied Consent and it was sent to a Georgia Bureau of Investigation crime laboratory in Panthersville, Georgia.
