Orange County Sheriff Jerry Demings says Walt Disney World has been providing “amazing” support as they search for the body of a 2-year-old boy who was snatched by an alligator.

Experienced alligator trappers, sheriff’s department divers and sonar equipment are being used to search a network of man-made canals, ponds and lakes where the gator may have taken the boy.

The sheriff says that after 15 hours of searching, the attack is “certainly not survivable at this point.”

Demings says Disney has never had anything like this happen in 45 years of operations. He says the theme parks’ wildlife management system works diligently to keep guests safe from dangerous Florida creatures, removing or killing any alligators they find.

Disney is closing all beach areas in its Lake Buena Vista resorts after an alligator dragged away a 2-year-old boy at the Grand Floridian Resort & Spa.

The company announced Wednesday that it’s closing the beaches in “an abundance of caution.”

Officials say the little boy was wading at the edge of the Seven Seas Lagoon around nightfall Tuesday when an alligator estimated to be between 4 feet and 7 feet long dragged him under.

Orange County Sheriff Jerry Demings said the family of four from Nebraska arrived on Sunday in Orlando, where only hours earlier, a gunman’s attack on a gay nightclub left 49 people dead. Two days before that, 22-year-old Christina Grimmie, a contestant on season six of “The Voice,” was killed in Orlando while signing autographs after a show.

The Orange County sheriff says the boy was wading in the Seven Seas Lagoon at Walt Disney World on Tuesday evening when an alligator dragged the child into the water. Authorities are still searching for the child.
