FLORIDA, United States (AFP) — One US family’s Disney vacation has turned to tragedy: The body of a two-year-old boy snatched by an alligator at the shore of a resort lake and dragged underwater has been recovered, authorities said yesterday.

The nightmare at the Disney World complex is the latest horror to hit the central Florida vacation town already reeling from Sunday’s massacre at a gay nightclub in which 49 people were killed — the deadliest mass shooting in American history.

Walt Disney World said it has shut down all of its Florida resort beaches and marinas out of precaution after the incident — the first such death in its 45-year history.

The boy’s father tried frantically to save him during the attack Tuesday night at a lakeside beach at the Grand Floridian Resort and Spa, but could not pry the toddler from the gator’s grasp. His body has now been recovered.

“His body was completely intact… The body has now been turned over to the Orange County medical office for an autopsy,” County Sheriff Jerry Demings told reporters.

The two-year-old victim was identified as Lane Graves of Elkhorn, Nebraska, a suburb of Omaha. His parents are Matt and Melissa Graves, Demings said.

“Of course the family was distraught, but also, I believe, somewhat relieved that we were able to find their son with his body intact,” Demings said.

The gator struck around 9:00 pm Tuesday as the child was playing in roughly a foot of water at the Seven Seas Lagoon outside the Grand Floridian, which is right across the lake from the Magic Kingdom.

The lagoon is man-made but connected to a natural lake. And alligators — common to Florida — can travel over land. Both help explain why there were gators in the body of water.

The boy’s father fought the alligator — estimated to be between four and seven feet (1.2-2.1 metres) long, according to reports — but the animal and child disappeared underwater, officials said.

Rescuers used sonar and floodlights to pursue their search overnight as a helicopter hovered overhead. Firefighters stood on the water’s edge with infrared cameras scanning the water for the child.

At least five gators have been captured and are being analysed, authorities said, adding that one of them may have been the one to attack Lane.

“Remember, it is Florida. And alligators are indigenous to this region of the country,” Demings said.

“Disney has a wildlife management system that is in place and they have worked diligently to ensure that their guests are not unduly exposed to the wildlife here in this area,” he added.

Alligators are common in Florida, but it is very rare for them to attack humans, Nick Wiley from the Florida fish and wildlife service told reporters.

Before this incident, there had only been 22 deaths from unprovoked alligator bites documented in Florida since 1948, according to the service’s website.

There was a no swimming sign at the lake, but no warning about alligators, he added.
