LAKE BUENO VISTA, Fla. – Walt Disney World resorts will place alligator warning signs near all of the waterways on their property, a source tells CNN. The signs are expected to go up as soon as possible.
On Thursday Disney was reviewing the number of signs on its property as well as sign placement and wording on signage and warnings, according to a statement.
"All of our beaches are currently closed, and we are conducting a swift and thorough review of all of our processes and protocols," the company said in a statement.
Orange County Sheriff Jerry Demings said the body of Lane Graves was found Wednesday afternoon.
The incident happened about 9:30 p.m. Tuesday in a sandy waterfront area outside the Grand Floridian Resort & Spa near the Seven Seas Lagoon on hotel property near Magic Kingdom, prompting Disney to close all of its resort beaches "out of an abundance of caution."
Authorities said the Graves family, who are from Nebraska, were on the beach for movie night at the resort.
Witnesses said Lane's 4-year-old sister was in a playpen about 20 or 30 yards from the water on the sand, and Lane was playing along the edge of the lake with his father when he was dragged into the water by the gator.
An army of first responders searched for Lane, but after 15 hours, it turned into a recovery mission. A diver found the toddler's body just 15 yards from where his father tried to save him.
"The body was intact. There is no question in my mind that the child was drowned by the alligator," Demings said.
Demings said a Catholic priest accompanied him to deliver the news about the boy's body being found to his parents. He said the family was "distraught but somewhat relieved" that authorities were able to find their son with his body intact.
"Words cannot describe the shock and grief our family is experiencing over the loss of our son," the family said in a statement to ABC News. "We are devastated and ask for privacy during this extremely difficult time. To all of the local authorities and staff who worked tirelessly these past 24 hours, we express our deepest gratitude."
Officers said there are signs stating "No swimming allowed," but nothing warning guests about alligators, which tourists have previously captured on camera in the area.
"There are no words to convey the profound sorrow we feel for the family and their unimaginable loss," Disney World Resort President George A. Kalogridis said in a statement. "We are devastated and heartbroken by this tragic accident and are doing what we can to help the family during this difficult time. On behalf of everyone at Disney, we offer our deepest sympathies."
Nick Wiley with the Florida Fish and Wildlife Conservation Commission said five alligators were taken from the water during the search.
