The death toll rose to two today following a stampede at a rap concert in Rochester, New York, that authorities said may have been triggered by unfounded fears of gunfire.

The Memphis rap stars GloRilla and Finesse2tymes had finished performing Sunday night at Rochester’s Main Street Armory when something prompted people to surge dangerously toward the exits just after 11 p.m., Police Chief David M. Smith said at a news briefing Monday.

“We do not have any evidence of gunshots being fired or of anyone being shot or stabbed at the scene,” Smith said.

Concertgoer Ikea Hayes returned to the venue today to retrieve belongings she left behind.

“I was watching my life flash before my eyes, and I still didn’t even know what was going on,” she told Rochester television station WHEC. She described being “on the ground, just scared, praying, like, you got to get up, you got to move. If you stay here, they’re going to keep running you over. So, you got to get up. You got to move.”

Police found three badly injured women in the auditorium. One, Rhondesia Belton, of Buffalo, died at a hospital. Belton, 33, worked for Buffalo’s Traffic Violations Agency, Buffalo Mayor Byron Brown tweeted Monday evening.

“Her family, friends, and colleagues are devastated and left to mourn this tragic loss,” Brown said. “Please keep her family in your thoughts and prayers.”

Rochester Police announced the death of a 35-year-old woman late today. Her name was not released. Another woman remained in critical condition, police said. Seven additional people were treated at hospitals for injuries that were not life-threatening.

Security guard Anthony Rouse told WHEC he signed up to work when he learned his daughter was going to the concert. She was hurt in the rush to the exits and spent part today in the hospital, he said.

“The whole reason I signed on was to protect her,” he said. “And I failed.”

Rouse said he was near the stage when his daughter went down near the entrance of the crowded hall.

“What began last night as a night of live music and fun for the performer GloRilla ended in tragedy,” said Smith, the police chief.

While there is no evidence of gunfire, Smith said, police are investigating several possible causes of the fatal surge, including “possibly crowd size, shots fired, pepper spray and other contributing factors.”

Mayor Malik Evans called the fatal stampede “totally unacceptable” and promised a thorough investigation into whether venue operators had the necessary safety measures in place for a large crowd.

“We are going to hold people accountable for what happened last night, period,” Evans said, though he cautioned that it was too early in the investigation to assign blame. “I intend to get to the bottom of this.”

There was no response to emails requesting comment sent Monday to the Main Street Armory.

GloRilla, whose 2022 song “F.N.F. (Let’s Go)” with Hitkidd was nominated for a Grammy for best rap performance, tweeted that she was “praying everybody is ok.”

Fatal crowd surges have been a recurring disaster at concerts and other large events in the U.S. and around the world, including one at a 2021 concert by rapper Travis Scott in which 10 people died.

Built from 1905 to 1907 and initially used by the U.S. Army, the armory hosted sporting events throughout the 20th century before being shut down for several years starting in the late 1990s, partly because it lacked a fire suppression system at the time.

It reopened after extensive renovations and began hosting concerts and other events in 2005. Smith said its main arena is meant to have a capacity of about 5,000 people, and the city fire marshal will work with police to determine whether that capacity was exceeded Sunday.

City officials said the facility underwent a physical fire safety inspection in December and was compliant with fire codes.

The venue’s next scheduled show, a Saturday performance by the rapper A Boogie Wit Da Hoodie, has been canceled.

“If you go to a concert, you do not expect to be trampled,” Evans said. “Your loved ones expect you to be able to come home and talk about the experience that you had at that great concert.”
