RedactedNarrative: On July 13, 2018, at 1951 hours, I, Officer, of the Maryland Natural Resources Police was on boat patrol in the area of Rolphs Wharf on the Chester River when I received a call from DNR communications in regards to several individuals in distress in the area of the Corsica River and Conquest beach. Using my NRP patrol vessel, I responded to that location. When I arrived at 2001 hours, I observed an overturned sailboat with several occupants in the water, and standing on the hull. 
  
  These individuals told me that there was a white female wearing a white tank top and dark colored shorts who got trapped underneath the sails when the vessel overturned. She had not returned to the surface of the water. They stated that there were 17 people on board at the time of the incident and only 16 accounted for, including 1 individual whom had already been taken to shore. The vessel capsized between their current location of N39 degrees 05.541/ W076 degrees 09.155 and the Red/Green"CR" channel marker at the mouth of the Corsica River. These individuals stated that were okay and would be attempting to "right" the sailboat. 
  
  I relayed this information to Kent & Queen Anne's County Fire Board and then began rendering assistance and conducting a shoreline and surface search of the area. Kent County Fire Board, Queen Anne's County Fire Board, United States Coast Guard, Maryland State Police and several NRP units conducted a search of the general area until approximately 0530 hours on July 14, 2018. We were unable to locate the missing person. Corporal from NRP assumed responsibility for the investigation. All events occurred in Queen Anne's County.
  
  The on scene lead for Queen Annes DES, declared the scene a Mass Casualty Incident (MCI), and established the command post at Roberts Farm Lane as the triage point. Victim was last seen wearing dark colored denim shorts and a light grey graphic tee shirt. She was described as a petite blonde with tattoos on her right forearm, and left bicep. She was not wearing a lifejacket, and was reported as a competent swimmer. Units from NRP, Queen Annes Fire, and the USCG, began a surface search. The USCG and MarylandState Police aviation units began observation flights. All search grids for marine and air units were coordinated through USCG Lt.  at Station Curtis Bay, Maryland National Capital Region. These patterns and report are included in the attachments.
  
   The weather was clear with a light wind, less than 5knts from the south. Waves were flat, and the water and air temperatures were in the low 80's. There was low vessel traffic on the river.
  
  Crew on board the sailboat indicated the vessel overturned while making a turn, when the sails caught a gust of wind. Crew members indicated this is not uncommon in these types of racing hulls. Victim was believed to have become tangled under the sail or underneath the hull of the boat. The crew performed safety measures, checks, and searched for the victim in the overturned vessel and sails, without success. Queen Annes County EMS established a triage center at Richards Farm Lane, Centreville, MD, and transported the 16 crew to shore. Sgt. of the Maryland Natural Resources Police obtained written statements from the crew, after they were evaluated by EMS. 
  
  One crew member was seated behind the victim and wearing a GoPro brand camera. He was identified as the victim's boyfriend. He told me this was the victim's first time sailing and that he had been trying to convince her to try it for almost a year. This camera recorded the vessel operation leading up to and including capsizing and search efforts. In the video, the victim can be seen jumping into the water, with the majority of the crew, as the vessel heels comes to rest on its port side. The video does not show her resurface when it pans back to the area where she entered the water, and she is not observed in any of the underwater footage from the search of the hull and sails/rigging. A copy of this video was transferred to my state issued MDT, and a copy was made onto a flash drive, which will remain in the physical case file. After triage and accounting for all crew members, apart from the one reported missing, one occupant of the vessel "Mystery" was believed by EMS to have a fractured foot, however, he refused transport. 
  
  Queen Annes DES returned their units to service after exchanging information with me at approximately 2200. Queen Annes Fire vessels remained on scene and participated in the search. The vessel owner has owned and sailed the vessel "Mystery" since 1972. He reported that he is also the owner and was the operator of the chase boat, with two other adults and three children, when "Mystery" capsized. Owner identified the operator of "Mystery" that evening. This was confirmed by Operator in his written statement. 
  
  
  The victim’s family advised me other the following: Victim lived in Easton with her sister, and was dating occupant, who lived in the adjacent apartment. They were in good standing together, and had been planning on becoming engaged in the near future. Both Victim and Occupant were in recovery together, and had both been sober for sometime. Victim was able to swim, but was new to sailing. Occupant has about 12 years of experience sailing on the "Mystery", and was Victim's safety partner. Victim has no known medical conditions or medications, and has two scars: one on the lower abdomen from a childhood surgery, and a second on the right bicep from an abscess that was removed. She had many tattoos, some of which were visible in screenshots taken from the GoPro footage. These screenshots of Victim were disseminated to marine units assigned to the surface search to aid in identification. Units from NRP and USCG will remain on scene overnight, and continue surface searches through the morning. NRP marine assets would perform a shift change at 0600 on 14 July, and SOD Sgt. was coordinating NRP dive unit to respond the next morning as well. I updated USCG Lt. of the above information, and coordinated overnight search patterns from USCG Station Annapolis vessels and Air Station Cape May's aviation units. Sgt. coordinated further with Maryland State Police Aviation Command, and arranged fo
