RedactedNarrative: On Sunday October 5, 2014 at approximately 1814 I Officer with the Florida Fish and Wildlife Conservation Commission was on routine water patrol in my marked police vessel. I was in the vicinity of Palm Valley when I heard the Coast Guard announce a Pan-Pan over the VHF radio; the message was in regards to a vessel that had beached in Hannah Park. The vessel was reported as unmanned with the engines still running. At this time I called Coast Guard Sector Jacksonville identified myself as a police officer with FWC and asked if they had any additional information regarding the Pan-Pan and if they needed additional assets to help with the call. Coast Guard Sector Jacksonville stated they had little information to go on but did request FWC‘s help in patrolling the Mayport Jetties and the shoreline for any possible persons in the water. 
  
  At this point I contacted FWC Dispatch Officers and informed them of the situation. I proceeded to the location using my police lights and siren to go through the slow speed zones; I arrived on scene at 1840. Upon arriving on scene I observed a Coast Guard vessel and approached them to see if they had any additional information. The Coast Guard crew stated that there was no additional information and they were awaiting orders from there chain of command. At this point we had not located the beached vessel. The Coast Guard Vessel and I proceeded south of the Mayport jetties and followed the shoreline until I observed a vessel that appeared to be completely out of the water on the shore of Hannah Park. Due to the ocean conditions I was unable to get close to the vessel to make out any registration numbers, l could observe several JSO Officers standing by the vessel. I asked FWC Duty Officers to contact JSO and pass my cell phone number along to the Officers on scene. 
  
  I received a call shortly after from a JSO Officer on scene he informed me that they had been able to run the documentation numbers of the Vessel (DO1245104) and determined the owner was the only vessel occupant by locating a float plan on the vessel. The JSO Officer also stated Officers were on scene with family at his home and they provided the same information. The JSO Officer then informed me that good Samaritans had watched the vessel drift up to the beach with no one onboard and the engines still running. 
  
  I began searching the south jetties and followed the shoreline south down Mayport. I did not observe anything in the water during this time. I continued this search pattern until visibility was zero and headed back inshore at 1953. When I arrived back at the boat ramp I then headed to Hannah Park. I was met at the Hannah Park gates by several JSO Officers who informed me on all the information they had received, JSO had been able photograph the GPS track of the vessel and made contact with operator’s girl friend who was currently on scene. I was introduced to Girlfriend briefly; she stated that she had received several text messages from Operator throughout the day with the last one being at 1315. She stated that Operator had taken his boat out because he had recently had work done on the fuel gauge. He planned to only be out a short time and wanted to be home by 1300 to “catch the Jags game”. In the last series of text messages between Operator and Girlfriend, Operator stated that the vessels VHF antenna had gotten lose. The last text message from Operator stated “I rig it”. There was no contact between Operator and anyone else after that point. 
  
  I proceeded down to the vessel to conduct a preliminary investigation; the vessel appeared to have sustained no damage from the beaching and was in very good condition. The vessel had all required safety equipment in plain view a lifejacket was even hanging next to the captain’s chair. There was no alcohol on the vessel.
