RedactedNarrative: On July 16, 2017, at approximately 1115 hours, I Ofc. Maryland Natural Resources Police responded to the report of a head injury victim on a vessel near the Harry Nice Bridge. While responding to the bridge I received notification that the victim had made contact with EMS at Aqualand Marina, and EMS was taking the victim to Charles County Regional Hospital. After receiving notification of the victims status I change my response to meet the victim at the hospital. 
  
   Once I arrived at the hospital I received information from the emergency room staff that it was a 10 y/o female, and the EMS unit was en route. Shortly after my arrival, the victim who was later identified, arrived to the emergency room with her father. 
  
   Father explained to me that Victim, and two other children were on a tube being pulled on the Potomac River just south of the Harry Nice Bridge when they heard a piece of debris/ wood hit the bottom of the vessel. Upon hearing this sound they noticed a piece of wood fly up behind the vessel and strike Victim in the face and knock her off of the tube. Father said that it appeared to be a 2x10 board that was lying under the water and when the vessel hit it, it broke and the broken piece is what flew up behind the vessel. Victim and the two other children on the vessel were all wearing life jackets. Victim at no point loss consciousness per family on the vessel. At this point, the vessel owner/ operator quickly turned the vessel around, Father jumped into the water to get Victim and bring her onto the vessel. They immediately noticed a large gash/ injury to Victim's forehead and called 911. EMS responded and met the vessel at Aqualand Marina where the patient was taken to the hospital. 
  
  Another subject stated that it was a calm day, with no wake and at no time was he able to see the piece of wood. 
  
   I obtained all information on everyone who was onboard the vessel. All children including the ones on the vessel were wearing life jackets. 
  
   Victim after being evaluated at Charles County Regional, was determined to have a skull fracture, and bleeding behind the fracture. Doctors advised she was going to be flown out to Children's in District of Columbia. I made contact with family on July 17, 2017, who stated she was stable, and had a metal plate surgically placed in her skull due to the fracture. 
  
   All events occured in Charles County, Maryland.
