Discovery Cove: Cardiff girl drowned at Florida theme park – inquest

But despite doctors’ efforts, she died at 17:22 on 31 May.

A post-mortem examination was carried out at the hospital, with the cause of death given as drowning, followed by seizure disorder, the inquest was told.

Area Coroner Patricia Morgan said she was opening a formal investigation because she had “reason to believe the death was unnatural”.

Ms Morgan said the investigation would focus on Anna’s “past medical history and the circumstances leading to her sad passing”.

She said it would require further information to be obtained from Florida and adjourned the inquest.

“I wish to express my condolences to the family of Anna Beaumont at this sad time,” she said.

Anna, a pupil at Radyr Comprehensive School, was previously described by her family as “a beautiful soul”.
