RedactedNarrative: On Saturday, 6/27/2020 at 1735 hrs, OFC. and I received a call in the area of Battle Creek, Patuxent River for a person who had jumped off of a boat onto the propeller. While enroute, Calvert Control Center advised that the injured subject was going to be transported to University of Maryland Medical Center in Baltimore by MSP Trooper. We arrived on scene at 1755 hrs and located the vessel involved, bearing Virginia registration VA 8535 BS, which was unoccupied. Photographs of the vessel were taken at this time.
  
  Several minutes later, a female waded out towards our patrol vessel, indicating that she had been a passenger on the vessel. 
  
  I made contact with Operator, who indicated that he had consumed one beer prior to the accident. At 1846 hrs, I performed the Horizontal Gaze Nystagmus test on Operator, distinct and sustained nystagmus at maximum deviation was observed in both eyes. Operator indicated that he had previously burned his corneas, and occasionally had issues with his eyes. Although no other indicators of impaired were present, Operator requested to submit to a Preliminary Breath Test. PBT was administered at 1853 hrs, resulting in .000 BAC.
  
  Operator was transported back to his vessel, where a safety equipment inspection was conducted and Operator provided a written statement. Operator was then  released from the scene. 
  
  OFC made contact with the victim at UMMC. Victim refused to provide a statement.
  
  At 2244 hrs, I met with Dickson at the Solomons Volunteer Rescue Squad Fire Department, where she provided a written statement. 
  
  Based on the statements obtained, it was determined that the following occurred. Operator, and three others departed Solomons Landings and headed to the sand bar at Battle Creek. Operator was operating his 1990, Searay, 190L, white and yellow in color. The passengers had consumed an unknown amount of alcohol prior to departing on the vessel. Operator stated that he consumed one beer on the way to Battle Creek and the passengers continued to consume alcohol. Operator stated that prior to the accident Victim was noticeably impaired, but not "sloppy drunk".  
  
  They arrived at Battle Creek at approximately 1628 hrs. Due to the number of boats in the area and on the sand bar, there was no room for Operator to beach the boat. He decided to anchor the boat approximately 25 yards from the shore. Operator stated that he trimmed up his outdrive due to the shallow water and was having trouble maneuvering the vessel due to the wakes from high amounts of boat traffic. Subject1 was at the bow of the boat and deployed the anchor. Operator asked Victim to assist with positioning the stern of the boat. Before Operator could turn the ignition off, Victim jumped off the back of the boat, directly onto the propeller. Operator stated that the boat was not moving, but he is unsure if the vessel was in neutral or forward, due to a sloppy shift linkage. 
  
  As a result of contact with the propeller, Victim had lacerations to both legs. Victim's left leg had the most severe injuries. Operator and subject1 are both certified EMTs, and rendered immediate first aid. They applied a pressure dressing to the left leg which was unsuccessful at stopping the bleeding, so a makeshift tourniquet was applied. They contacted 911 and transported Victim to the shoreline with assistance from other people at the sand bar. EMS arrived on scene, began treating Victim and transported him to UMMC.
    
  All events occurred in Calvert County, MD.
