ORLANDO, Fla. (AP) - Authorities say a 7-year-old Massachusetts boy who died at a hospital after spending the day at SeaWorld Orlando had a heart condition.

The park said in a statement: "Our thoughts and prayers are with the family in this most difficult time."

The boy was visiting SeaWorld's Aquatica water park Thursday afternoon when he was taken to Dr. P. Phillips Hospital by Orange County Fire Rescue. Park paramedics had also treated the child.

Orange County Sheriff's Office spokesman Jim Solomons says the child was from Taunton, Mass.
