RedactedNarrative: On 6/19/14 at approximately 5:00pm, a boating incident resulting in a fatality, drowning, occurred on lake twitty 1/4 mile southeast of the lake twitty public boat ramp. The vessel was an 18 ft generation iii aluminum bass boat with a 40 hp outboard motor. The vessel was owned and operated at the time of the incident. There was only one passenger, 18 year old operator’s grandson, on board the vessel. While fishing with his grandfather in a local bass tournament, occupant fell overboard and did not resurface. 
  
  According to operator, he and his grandson, occupant, participated in this bass tournament on a regular basis. After launching their boat, they traveled 1/4 of a mile down the southeast side of the lake to a favorite point. This is where they started fishing in approximately 9 feet of water. Operator stated he was fishing off the front, bow of the boat, which is contradictory to a statement that is included by another agency in this report. This may have been due to stress as the incident had just happened minutes earlier. Occupant was on the back/stern. Subject stated after making one or two casts, he heard a splash in the water and turned to see what it was. He then realized occupant was no longer in the boat, so he jumped in to try to retrieve him. Operator was unsuccessful in locating occupant so he called 911. Occupant was not found until 6/21/14 at 9:00am he still had his fishing reel in his hand. Operator stated that occupant had seizures weekly, sometimes daily. He said, he was sure that this is what happened as occupant was a good swimmer. 
  
  In conclusion, it appears occupant had a seizure causing him to tense up and lose his balance. This resulted in occupant falling overboard and drowning due to his medical condition.
