Victim and Subject were both in a canoe in the Sunflower Rover behind North Circle.  The water was too swift causing the two men to collide into tree limbs.  The limbs knocked both men out of the boat.  Subject made it to the bank to call for help.  Subject stated that he left Victim hanging onto one of the tree limbs.  Once Subject made it to the bank he looked back and Victim was gone. 
It was determined by the investigating officer that alcohol use in dangerous waters caused the accident.  MS law states that vessel must be motorized for operator to be charges with Operating under the influence.
