Heat exhaustion is the cause of death of a Brazilian fan who attended a concert of singer Taylor Swift in November, a forensics report obtained by The Associated Press on Wednesday shows. 23-year-old Ana Clara Benevides passed out during Swift's second song in the Nov. 17 concert in Rio de Janeiro, “Cruel Summer,” and died hours later at a local hospital. Fans lined up for hours before the show, and many accused organizers of failing to deliver enough water supplies for the more than 60,000 attending the concert at the Nilton Santos Stadium.
