subject was driving IA4514BJ, with 7 passengers.  The boat started out at 10:00 pm and traveled around the lake, went to a bar and then went out to the bridge and out beyond the buoys in East Okoboji.  Around 1:00am two people wanted to go swimming.  Occupant1 put a life jacket on, Occupant2 refused a life jacket and the two jumped into the water.  They swam for 10 minutes, Occupant2 again refused a life jacket and they continued swimming. Around 1:47am Occupant1 asked where Occupant2 was.  Nobody heard a cry for help, scream or any other indication that Occupant2 was in trouble.  The boat immediately called 911 and started searching the water with flashlights for Occupant2.  The boat was advised to drop anchor, which they did to give rescue teams a starting place.  Occupant2's body was found by the Spirit Lake Fire Department Rescue Dive Team at 6:58am.
