Taylor Swift was welcomed to Brazil on Thursday by a projection that made the world-famous Christ the Redeemer statue in Rio de Janeiro appear as if it were clad in a T-shirt similar to the one she wore in her “You Belong to Me” music video and was decorated with symbols from her songs.
But tragedy and trouble have followed that warm welcome.
A fan died in the sweltering heat at Friday night’s show in Rio de Janeiro. At the 11th hour, Ms. Swift postponed her Saturday show until Monday, to the dismay of thousands of fans who had already started filling the stadium. The military police said a fan who was in Rio de Janeiro for the regularly scheduled concert on Sunday was stabbed to death earlier that morning.
The fatality and other problems were a departure from the triumphant first leg of Ms. Swift’s Eras Tour, a career-spanning production that broke records in North America. As the tour’s second show in Rio de Janeiro approached on Sunday night, fans grappled with ruined travel plans, extreme heat and disappointment.
Anne Di Motta, 30, a psychologist in São Paulo, Brazil, was supposed to attend the Saturday night show and said she would be returning home before the rescheduled concert on Monday because she had to work.
“I spent the last 17 years waiting for the opportunity to go, to fulfill my teenage dream of meeting someone I’ve known since her first single,” Ms. Di Motta said. “And to be sitting three hours in a chair, completely wet with sweat, having to overcome several personal challenges to be there completely alone, to receive the news that it was canceled — it was completely devastating.”
The Saturday night show was postponed because of the extreme temperatures, Ms. Swift said in an Instagram post hours before the concert was supposed to begin at an open-air soccer stadium. “The safety and well-being of my fans, fellow performers and crew has to and always will come first,” she said.
At that point, thousands of fans had traveled to see Ms. Swift, enduring the peak of the day’s heat, which reached 93 degrees Fahrenheit, or 33 degrees Celsius, before they were asked to leave the venue.
A representative for Ms. Swift did not immediately respond to emailed questions about the postponement of the Saturday show.
“I bought water, I bought a fan, everyone is crying, screaming, so you show up on this stage!” Ms. Alvarenga said.
As crowds left the stadium, there were reports of unrest linked to gang activity near the site, a military police official said on Saturday night.
After Matheus Duarte, 24, a warehouse worker, left the stadium and went to a shopping mall nearby, he saw people yelling that there was a raid.
“I don’t really know if it really happened, but I saw desperate people running,” Mr. Duarte said. “And as soon as I saw it, I started running along and hid in a car park.”
On Sunday, the military police said there had been no reports of robberies or muggings the night before. But before the concert on Sunday, a fan in Rio de Janeiro for the concert was stabbed to death after an attempted robbery in Copacabana, the famous beachside strip, the military police said. Two men had been arrested, they said.
During Friday’s show, Ana Clara Benevides, 23, died after losing consciousness, officials said. She was pronounced dead of cardiac arrest after being taken to a hospital, according to city officials and the Brazilian company that organized Ms. Swift’s show, Time for Fun.
Ms. Benevides, a psychology student, had traveled from Rondonópolis, which is about 880 miles northwest of Rio de Janeiro, for the concert, O Globo reported. Her friend Emiliane Félix, 22, told O Globo that Ms. Benevides had been sending her friends photos of her outfits for the concert “for over a month.”
On X, the social media platform formerly known as Twitter, Ms. Benevides shared her excitement about the concert, writing on Nov. 7, “I don’t know what my purpose in life will be after I see Taylor.”
Fans at the concert on Friday complained about a lack of water and extreme heat. The heat index, a measure of how hot the air feels because of humidity, reached 139 degrees Fahrenheit, a record for Rio.
In an online post, Ms. Swift said she was “devastated” by her fan’s death. “I’m not going to be able to speak about this from stage because I feel overwhelmed by grief when I even try to talk about it,” she said.
Luiza Guimarães, 33, an economist said that she was disappointed it took so long for Saturday’s show to be canceled because some fans were already unsure if it would go on after Ms. Benevides’s death and were worried about the heat. “Really, the production of the show was very reckless and everything was very poorly managed,” she said.
Ms. Guimarães said that she doesn’t blame Ms. Swift for the problems and that she thought the musician must be “very, very discouraged.”
