Florida authorities have found a body believed to be that of a 2-year-old boy who was dragged off by an alligator Tuesday night at Disney resort.

The Nebraska toddler was playing in the water on a beach area near Disney's Grand Floridian Resort & Spa at around 9:16 p.m. Tuesday when the alligator snatched him and pulled him underwater in front of his horrified parents, authorities said. The father tried to get his son back, but wasn't able to, Orange County Sheriff Jerry Demings said.

Demings said the boy's body was spotted at about 1:45 p.m. ET Wednesday, and fully recovered at about 3:30 p.m.

He identified the parents as Matt and Melissa Graves from Elkhorn, Nebraska, and said the young boy was named Lane Graves. The Graves also have a 4-year-old daughter who was with them at the Seven Seas Lagoon when Lane was snatched, he said.

While an autopsy has not yet been done, "there's no reason to believe" the body recovered isn't Lane, Demings said.

The tragic discovery brought to a close a search that involved more than 50 law enforcement officials, including Marine units who relied on sonar equipment to scour the lake. Initially a search-and-rescue operation, Demings said at a noon press conference there was "no question" the boy was dead after so many hours underwater and that the hunt had turned into a recovery effort.

But he had vowed to continue searching until the boy's body was found.

"I just happen to have a 2-year-old grandson, so for me, this is a very human experience that we are talking about, where we are dealing with this family now who there's no question will lose a 2-year-old child," he said at the earlier press conference.

In announcing Lane's remains had been found, Demings revealed that his body was "completely intact," and said while his parents were devastated, they were "also somewhat relieved" that his body was found.
