RedactedNarrative: Cpl. was on boat patrol on the Elk River in the area of Hollywood beach at approx. 1910hrs.. I heard a call for Mayday on the VHF radio.  They stated there was a vessel on fire in the Bohemia river. I switched on my emergency lights and  headed in the direction going code. When I came around Town Point, I could see the vessel on fire. 
  
  Upon arrival on scene, a good Samaritan who was operating a PWC made contact with me and stated he had one victim on board and  that there was another victim still missing. He proceeded to take her to his dock which was approx. 200-300 yards away. I scanned the water looking for the other victim, at the same time, I called into DNR communication to let them know that one victim was being taken to shore and there was another still missing. I continued to scan the surface of the water but I only saw debris from the vessel. Another vessel that was searching pointed at the water and yelled there he is. I could not see him immediately due to the sun glare. Another good Samaritan rushed over jumped into the water and grabbed him as I pulled up to him. We tried to lift him into my patrol vessel. but he was too heavy.  
  
  Good Sam1 had returned on his PWC. He jumped into the water and help us get the second victim into the stern of my vessel. The second victim did not have a pulse and was not breathing. He had a compound fracture of his lower right leg.  At 1919hrs. I started performing CPR on the victim with chest compressions. I continued for a while until another good Samaritan who was an off duty nurse came over boarded my vessel and relieved me from doing chest compressions. I retrieved a pocket mask from my first aid kit. She started giving breathes while I performed chest compressions. Both good Samaritan's helped to get my vessel over to Good Sam1's dock where EMS was going to stage while the female good Samaritan continued to give breathes and me chest compressions; switching to give each other a break from chest compressions. 
  
  When we arrived at the dock  Victim still did not have a pulse. EMS and Hack's Point Volunteer fire co. arrived on scene and took over giving chest compressions. They also brought a thumper to continue giving chest compressions. They also checked for signs of any vitals with negative results.  At 1948hrs. they called it and the victim was pronounced deceased.  I notified DNR communications and asked them to contact NRP SOD to get an investigator on scene.  The victims wife was taken by EMS to  station 9 firehouse. I spoke to Good Sam1 briefly, who stated that he was in his home when he heard a loud explosion and could see the vessel on fire and immediately calling 911. 
  
  Later, the Medical Examiner and our criminal investigator (Cpl) arrived on scene. 
  
  The dock where we were located was approx. 5' from water level making extremely difficult to get the victim off of the vessel and into the ME's transport. Once Cpl arrived they decided to have me take the victim to Hack's Point marina were it would be easier to get the victim into the transport van. Once the transport arrived, with the assistance of the Hack's Point fire department, the victim was moved into the transport van where he was taken to the Medical Examiner's Office in Baltimore. All events occurred in Cecil County, MD.
  
   On Saturday, July 30, 2022, at approximately 2009 hours, I was requested by NRP SOD Sgt. to respond to the area of Veazey Cove in Cecil County to investigate a fatal boat explosion. While en route, I contacted Cpl. and Ofc. who advised me that a boat, later identified as a 33’ Sea Ray, had exploded then caught fire.  
  
      Historical weather data for 1910 hours on July 30, 2022, was accessed through ambientweather.net.  The weather station was privately owned and was located approximately 1.75 miles Northeast of the scene. The temperature was reported to be 85° Fahrenheit. The wind was approximately 1.6 miles per hour out of the West Southwest. The sky was clear. The water temperature displayed on the NRP Patrol Boat Garmin chart plotter was approximately 85°Fahrenheit.
  
       Upon my arrival, I met with good sam1 who escorted me to the dock where the NRP patrol vessels were. Also, already on scene was Forensic Investigator.  Cpl. told me a man was thrown from the stern of the boat by the force of an explosion, then the boat caught fire after the explosion. A woman was in the cabin at the time of the explosion. Occupant exited the cabin via a forward hatch and jumped into the water from the bow. Cpl1 rescued Victim onto his patrol boat and began CPR. Good samaritans boarded Cpl1’s patrol boat and assisted with lifesaving efforts until they met EMS at the private dock.  Cpl1 stated that one of the Good samaritans identified herself as a nurse.  EMS continued lifesaving efforts until Victim was pronounced deceased at 1948 hours. Occupant was uninjured and was transported by EMS to Hacks Point Fire House to wait for her daughter to pick her up.
  
        After inspecting and photographing \ body located on the NRP patrol boat. Cpl1 and Ofc. transported victim on the boat to Hacks Point Marina to meet the transport company.  Before leaving the private dock, FI and I briefly interviewed Good sam1.  Good sam1 stated that he was in the house and saw the explosion and called 911.  Good sam1 said, “the back of the boat exploded”. Good sam1 showed us his phone, which showed the call was placed at 1909 hours. Good sam1 stated that the call was placed a minute or two after the explosion. Good sam1 also stated that he was in the military and the explosion felt like a roadside bomb. Good sam1 said that the concussion rattled the windows on the house.  Good sam1 then told us that he got on a PWC and rescued the woman later identified as Occupant and transported her to the private dock.
  
      FI and I then went to the Hacks Point Marina, where we were met by NRP Sgt. and Investigator. After updating Ofc. and Sgt., I went to the Hacks Point Fire House where I met Occupant. When asked, Occupant said they were preparing dinner.  Occupant said that the grill was hot, and they were getting ready to put the food on the grill. Occupant stated that she was in the cabin heating food in the microwave, so the generator had to be running. Occupant said that the back of the boat exploded and when she looked out the open cabin door, she said the back deck where her husband had been, was gone. Occupant said when the boat exploded, the mirror in the cabin shattered and the ceiling fell in.  Occupant stated that the back of the boat was on fire, so she climbed out of the bow hatch and jumped off the front of the boat.  When asked, Occupant said the grill was a charcoal grill and it was on the port gunwale. I asked how deep the water was and Occupant said when they were swimming it was waist deep and she said three – four feet deep. When I asked about Victim’s medical history and swimming ability, Occupant stated that Victim just started a blood pressure medication, and he was a SCUBA diver and was trained in rescue diving. After meeting with Occupant, I met with her daughter and son
