The body of the missing 2-year-old boy has finally been located after an exhaustive search ... and after analyzing the remains, cops believe the alligator drowned the child.
The name of the boy was also released ... 2-year-old Lane Graves from Elkhorn, Nebraska -- and his parents, Matt and Melissa.
The Orange County sheriff said Lane's body was located 10-15 yards from where he was pulled under water ... in about 6 feet of water. They said the body is still intact.
A rep for Fish and Wildlife said they will run forensics on the 5 gators they've pulled out of the Seven Seas Lagoon to determine if one of them is responsible for the child's death. They said if they can't find a match ... they'll continue searching for the culprit.
As we previously reported ... there were no signs warning of alligators in the water at the Disney Resort.
