(CNN) -- A guest at SeaWorld's water park Aquatica in Orlando, Florida, was pulled from a pool and later pronounced dead over the weekend, park officials said.
A lifeguard found a 68-year-old international visitor unresponsive Saturday morning in the park's Roa's Rapids, a SeaWorld spokesman said.
"The park's lifeguards responded quickly and performed CPR until paramedics arrived," Nick Gollattscheck of SeaWorld Orlando said in a written statement.
The guest, whose name is being withheld temporarily, was taken to Dr. Phillips Hospital, were he was pronounced dead, Orange County Sheriff Jeff Williamson said. The Sheriff's Office is investigating the death by interviewing witnesses and the victim's family.
The guest's body was taken to the Orange County Coroner's Office for an autopsy, as is standard procedure during a death investigation, Williams said.
"Our thoughts are with the family during this difficult time," Gollattscheck said.
