RedactedNarrative: On 10-24-2015 at approximately 11:00 PM, I, Sgt. was notified of a possible boat accident on the Mississippi RIver (Pool 16).  Responding to Sunet Park (Rock Island, IL.), I met with Rock Island County Sheriff''s Police and the occupants of the involved watercraft (single boat accident).  I was advised by the occupants of the watercraft that as they were traveling up stream from the I-280 bridge, they realized that victim was missing (from the boat).  Though there were no witnesses, it is believed that victim fell from the watercraft.  Victim was last seen on the boat between river mile #476 and #477.  The occupants realized Victim was missing between river mile #478.5 and #480.
   
      Victim''s body was recovered on 11-04-2015 (downstream from the last known location).  An autopsy was conducted on Victim that indicated drowning as the cause of death.  All toxicology tests conducted on Victim indicated that he had an elevated ethanol level.
