RedactedNarrative: According to the three males interviewed at the Auquaramp Marina who were traveling southeast on the Ohio River heading for the Riverbend Music Center to see if any boats were anchoring for the Jimmy Buffet concert which was held the next evening. Shortly before they got to the I-275 bridge in Ft. Thomas, the boat hit a wake and tossed all four occupants into the river.  The vessel was submerged and floating upside down.  The lone female passenger swam to the Ohio bank immediately and walked to a business to call 911.  The three males stayed with the boat and did not notice that Female had swam to shore.  Injured victim1 made attempts to swim under the boat to look for Female.  Eventually, the three men swam to the Ohio bank at the Cincinnati water pump station and were picked up by emergency vessels.  All three males refused medical treatment at the scene but Injured victim1 complained of pain in his side.  Two days later Injured victim1 drove himself to Wellington Sports Medicine in Cincinnati and learned he had four broken ribs.  Female was transported that night to a hospital in Cincinnati and apparently received stitches to her forehead.  I have been unable to contact Female but she was interviewed by Cincinnati Police Officer.  Female drew a diagram of where everyone was seated in the vessel and according to the diagram she claimed Injured victim1 was operating the vessel.  I made several calls to Female and left messages but have been unable to talk with her.  I conducted field sobriety tests on oeprator.  Evidence showed him to be under the influence of alcohol.
