After reviewing all the physical evidence including statements from survivor, Fire Department personnel, and DNR Rangers, it is my opinion that subject was fishing with survivor by vessel on the Chattahoochee River below Jones Bridge Park on August 29, 2013.  At approximately 11:11 hours, the boat was drifting sideways; moving downstream with the motor off, it hit a downed tree in the river.  subject fell overboard into the river and drowned.  subject was not wearing a personal floatation device.
