RedactedNarrative: Occupant advised me that they had been out on their Jet Ski (DL 815 AH) when they ran aground just west of South Shore Marina.  She advised me that both her and her husband got off the Jet Ski and attempted to push it off the sandbar then pull it off by a rope. They thought they were in enough deep water to get on and leave the area.  The Jet Ski started to kick out mud so V1 turned off Jet Ski to get to deeper water.   She stated that during this process the victim started to have chest pain.  She then advised her husband to take a seat in the water at which point he lose consciousness and went into cardiac arrest.  She advised me that at his point she held his head above water called 911 and waved down a passing boat.
    On June 06, 2014 after conducting several interviews with witnesses and the Wife of the victim, I came to conclusion that V1 was deceased from cardiac arrest.  V1 had open heart surgery and triple by-pass in the year 2010.  The Jet Ski had no damage except for some small scratches and dings on outside of Jet Ski DL 815 AH. It was ultimately both inattentive operation and an unseen hazard.  The operator was unfamiliar with the inland waterway and ran aground on a sandbar in shallow water.
