RedactedNarrative: Update 11/16/18 Information from a go pro video on board at time of accident.  4 adults and 1 child were on an inflatable non powered vessel drifting when 1 adult male jumped in for a swim and the another male adult dove into the water pushing the vessel away in the process.  Neither appeared to be capable swimmers.  The 3rd male on board appeared to be trying to paddle towards the parties in the water but gave up and threw a seat cushion toward the two.  The surviving male was able to reach the cushion but the victim was further from the raft.  The video ended at that point in time.  Due to a language barrier interviews of the persons on board were not able to be conducted.  Victim was recovered the next day via dive team at 10:28 am.  
  Several variables were the cause of this accident.  There was an inadequate number of life jackets on board as well as the victim not being a strong swimmer.  The victim was too far away from the raft for anything buoyant to reach him.  The remaining parties on board due to inexperience, unfamiliarity with the water and the raft were unable to paddle the raft to the victim.
