RedactedNarrative: On 8/21/15 at approximately 20:00 hours the above parties went for a boat ride on the Ohio river.  At appoximately 22:00 hours state EOC Dispatcher received a call that a boat had capsized on the Ohio river near the I-24 bridge.  The boat was occupied by the 6 above people, 2 survivors survived the accident. Three others were recovered soon after the accident. The other bodies were recovered sunday 8/23/15 down river from the accident site.  Survivor statements indicate they were boating after dark using a small light to navigate and got to close to the dam and did not realize it until the boat started to be swept over the dam and capsized.  I was notified around 01:00 hours 8/22/15 and went to Baptist Hospital in Paducah to assist McCracken County Sheriffs Office.  While crews were searching the river no boat has been located at this time and nothing was found by dispatch as to what type of boat they were in.  According to statements by family the boat was between 14 and 18 feet in length and fiberglass construction and that is all that is known at this time.  Also there were 4 PFD,s recovered from the river and 1 child PFD recovered by McCracken county Sheriffs Office in the vehicle located at the ramp.  While talking to family members at the hospital the description of the boat varied greatly.  McCracken county detectives performed the interviews of the two survivors at the hospital and it was determined that no one was wearing PFD's at the time of the accident.  When I arrived the survivors had already gone.
