Taylor Swift Fan Died From Heat Exhaustion At Brazil Concert

Heat exhaustion was the cause of death of a Brazilian fan at Taylor Swift‘s concert … a forensic report confirms.

Ana Clara Benevides Machado passed out during Taylor’s Rio de Janeiro concert Nov. 17 amid the city’s oppressive heat — 105 degrees — and was pronounced dead hours later at the hospital.

Rio’s Forensic Medical Institute now reveals heat exposure led to a “serious compromise of her lungs and sudden death” — basically, in medical terms, she suffered a cardiorespiratory arrest.

The report notes she didn’t have any preexisting conditions or substance abuse issues that could have contributed to her death.

Rio’s public prosecutor has now opened a criminal investigation of her death … saying in a statement Wednesday representatives of the concert’s organizers, Time4Fun, will be called to testify following an in-depth analysis of the report.

Soon after the tragic incident unfolded at Estádio Olímpico Nilton Santos … fans demanded the organizers supply more water at the following shows because they weren’t allowed to take any into the venue themselves.

The company execs acknowledged their mistake shortly after … saying they “did not economize in our efforts or resources to follow the best global practices in our industry to guarantee the comfort and safety of all.”
