RedactedNarrative: On July 26, 2020 at approximately 1730 hours; I, Ofc. and Cpl., Maryland Natural Resources Police, were on boat patrol in the Potomac River in the area of the Big Slackwater Boat Ramp when we were flagged down by a vessel displaying State of Pennsylvania registration 9506 BP. The operator of the vessel stated they had an injured occupant aboard. The injured occupant was suffering from a dislocated shoulder. I asked Victim if he needed an ambulance which he stated he did. Cpl. and I told Operator1, the operator of the vessel, to proceed to the boat ramp so that Victim could wait on land for EMS.
  
       While waiting for the ambulance to arrive Cpl. and I gathered information from the occupants of the vessel and began to inquire how the injury to Victim occurred. Victim stated that he and another occupant were being pulled behind the vessel on a tube when the vessel and tube struck a large wake throwing Victim and Subject1 into the air and off of the tube. With Victim being ejected from the tube and subsequently impacting with the water, he dislocated his left shoulder. The injury was apparent to Victim and he was in a lot of pain while waiting for EMS to arrive. 
  
       An ambulance from Halfway EMS arrived on-scene to evaluate Victim. (EMS run number 2016056). The paramedic did confirm Victim had a dislocated shoulder. The EMS crew asked Victim if he wanted to go to the hospital with them, but Victim decided he would go on his own. Subject1 drove Victim to an Urgent Care for medical attention. A safety check of the vessel was completed and all required safety equipment was present. No alcohol was involved or onboard the vessel.
  
  All events did happen and occur in Washington County, Maryland.
