RedactedNarrative: I Officer of the Maryland Natural Resources Police was on routine patrol in Back River when I received a call for a boat fire near the Key Bridge.
  
  Coast Guard, Baltimore City Marine and Fire and EMS were on scene by the time Officer and I had arrived at 8:05. Coast Guard had rescued all 6 people that were on the boat.  Fire and Ems had the fire under control once we arrived. There were no injuries and all occupants were accounted for.
  
  I, Officer made contact with the owner of the vessel. I proceeded to fill out a NRP-412 Watercraft Accident Report. While speaking with Subject, I asked her what happened and she began to explain to me, they took the boat out of the boat ramp in Fort Armistead Park and while her husband was operating the boat Subject heard a noise and her Husband put the boat in neutral to listen to the noise. They tried to return back to the dock when the boat caught fire. They and their four children made the decision to jump into the water.
  
  Subject also informed me they just purchased the boat three days ago and did not have boaters insurance yet.
  
  While speaking to Subject we noticed their vessel (MD reg, 4680 AR) caught fire again after Fire and EMS had already extinguished the flames. Ems continued to put out the boat fire until the boat eventually sank to the bottom of the Patapsco River.
  
  All events occurred in Baltimore Country Maryland.
  
  It is unknown if the occupants attempted to vent the vessel.
