The alligator dragged the boy into the lake on Tuesday night while he was playing on the waters edge of a 'no swimming' area. After more than 15 hours of searching, his body was recovered ‘in tact’.
Witnesses described the alligator as being between 1.2 and 2.1 metres long.
During the search it was reported that five alligators were captured and euthanised.
Orlando Sheriff Demings said 'this type of thing' had never happened before.
