ORLANDO - The medical examiner's office in Orlando says a 2-year-old Nebraska boy died from drowning and traumatic injuries after being grabbed by an alligator at Walt Disney World.

The District 9 Medical Examiner's Office finished the autopsy of Lane Graves on Thursday and issued the cause of death.

Authorities recovered the boy's body intact Wednesday afternoon, less than 24 hours after he was snatched from the shore of a lake.

His family was vacationing at the Grand Floridian Resort and Spa at Walt Disney World.

It's an unwritten rule for Florida residents: Keep your kids away from ponds and lakes because alligators are everywhere.

But now, attention has turned to tourists.

Now people are asking: In a state with an estimated 1 million alligators, how should theme parks and other attractions warn visitors, and did Disney do enough?

Disney beaches remained closed Thursday after the death of Lane Graves. The company says it is reviewing policies that do not currently include posting alligator warnings around park waters.

Local law enforcement and state wildlife officials have publicly praised the company for spotting and removing nuisance gators from park waters.
