Disney Alligator Attack: Guest Sounded Warning Before Attack

EXCLUSIVE

A guest at Disney's Grand Floridian Resort saw an alligator looming in the area where 2-year-old Lane Graves was playing ... and she even sounded the alarm to someone at the hotel.

The Florida Fish and Wildlife Conservation Commission and the Orange County Sheriff's Office released a final report -- obtained by TMZ -- about the circumstances surrounding Lane's death.

According to the report, Shawna Giacomini, a North Carolina tourist, told investigators she was on the beach at 8:15 PM with her 2 daughters, and the girls saw an alligator about 5 feet from the shore, near the marsh. The older daughter told the Walt Disney World AV/Movie Coordinator about the gator.

The trio went to the store, and when they returned at around 9 PM the attack had already occurred.

The report details the attack, explaining Lane went toward the water with his dad and a pail. The dad saw a splash, looked over and saw the gator had locked onto Lane's head. He tried pulling the gator's mouth open, to no avail, and the gator dragged Lane into deep water.

The cause of death was cranio-cervical trauma and drowning.

The report is damning because of the lack of signs warning of gators, which the authors call "predatory."
