A pre-existing heart condition caused the death of a man who was stricken while riding a Walt Disney World roller coaster, the Orange County medical examiner's office said Wednesday.
Jeffery Reeb, 44, of Navarre, was unresponsive when removed from the Expedition Everest ride at Disney's Animal Kingdom on Tuesday.
He was pronounced dead at Celebration Hospital.
Everest debuted in 2006, simulating a runaway train ride through the Himalayas.
Following Reeb's death, the ride was reopened Tuesday afternoon after an inspection found it was operating properly.
Prior to Reeb's death, at least 15 people had died at Disney's theme parks in Florida and California since 1989, some with previous health conditions.
