RedactedNarrative: 7/10/2021:  At approximately 5:49 PM, I (CPO) responded to a personal injury boat accident near Grafton Harbor. On arrival at Grafton Harbor, the victim was being prepped for transport by the Jersey Community Hospital Ambulance. Victim was soon transported by helicopter to Mercy Hospital in St. Louis with a head injury.  I made contact with acquaintance who advised both his and Victims'' PWCs were still drifting down the river. 
  
  I relocated to my patrol boat and recovered both PWCs southeast of Island 526. The steering wheel of Victim''s PWC was broken and hanging from the vessel. Upon returning to Grafton Marina, I interviewed Subject1 on the incident. Subject1 advised he did not see the incident. He was operating upstream between Mason Island and Island 526 on his PWC when he observed Victim in the water near his PWC. Subject1 entered the water to render aid. Victim was face down in the water. Victim was initially unconscious but regained consciousness. A passer-by stopped, assisted in getting Victim into the boat and transported them to Grafton Harbor. 
  
  Subject1 admitted to consuming alcohol, but was not under the influence of alcohol. He claimed Victim too consumed alcohol, but was not under the influence of alcohol. 
  
  Officers were able to speak with him briefly. He had suffered injury to the front, left quadrant of his head. He was unable to recall how the incident occurred. CPOs observed no indicators of alcohol impairment.
  
  I maintained possession of Victim''s PWC pending investigation. On July 10, 2021, I utilized my Department issued boat lift to lift the PWC off the water. I inspected the hull, but observed no indication Victim had struck an object. I was successful in starting the engine. I discovered no indication the vessel was not working properly. The PWC contained all required safety equipment. See attached photographs. 
  
  At approximately 3:20 PM, I made phone contact with Victim''s girlfriend. Subject2 advised Victim suffered a traumatic brain injury. He had a skull fracture and subdural bleed. He had been discharged from the hospital on this morning and was recovering at home. Subject2 explained Victim described seeing debris in the river and attempted to "shift away" from the debris. He was unable to recall any other details of the incident. When asked, Subject2 confirmed Victim had recently had the PWC dewinterized and repaired at St. Charles Motorsports. Victim had operated the PWC twice since the repairs and described the PWC not performing properly. He suspected bad gas. 
   
  Upon completing my inspection of the PWC, I informed Subject2 of the opportunity to return to vessel to Victim''s possession. The return of property is forthcoming. The investigation is pending an interview with Victim upon recovery.
  
  07/19/2021 Update:  I made arrangements to return the PWC to Subject2 on July 11, 2021 at Grafton Harbor. On July 11, 2021, I discovered Subject1 had taken possession of the PWC without authorization. I discovered this occurred in an attempt to assist Subject2. I met with Subject2 and Subject1 at Yacht Club on the Missouri side of the Mississippi River.  The PWC had been trailered. While trailering the PWC, Subject2 advised she observed damage to the hull. She photographed the damage before securing the PWC on the trailer. I attempted to inspect the damage. I observed rub marks on the hull I suspected were consistent with normal wear. I could not observe additional described damage. Subject2 described the other markings were obstructed by the trailer boards. She provided me with photographs of observed damage. See attached photographs. Whether the damage was accrued from during the incident is unknown. I informed Subject1 of the legal concerns with him taking posses...
