HOUSTON (NewsNation Now) — Authorities said they would watch video, interview witnesses and review concert protocols to determine how eight people died at a Houston music festival when fans suddenly surged toward the stage to watch rapper Travis Scott.

City officials said Saturday they were in the early stages of investigating the pandemonium that unfolded Friday evening at Astroworld, a sold-out, two-day event in NRG Park with an estimated 50,000 people in attendance. One attendee said that as a timer clicked down to the start of Scott’s performance, the crowd pushed forward.

The crowd at the event suddenly surged toward the stage during a performance by Scott, squeezing fans so tightly together that they could not breathe or move their arms, witnesses said Saturday, hours after at least eight people died in the chaos.

“As soon as he jumped out on the stage, it was like an energy took over and everything went haywire,” concertgoer Niaara Goods said. “All of a sudden, your ribs are being crushed. You have someone’s arm in your neck. You’re trying to breathe, but you can’t.”

Goods said she was so desperate to get out that she bit a man on the shoulder to get him to move.

The dead ranged in age from 14 to 27, and 13 people were still hospitalized, Mayor Sylvester Turner said. He called the disaster “a tragedy on many different levels” and said it was too early to draw conclusions about what went wrong.

“It may well be that this tragedy is the result of unpredictable events, of circumstances coming together that couldn’t possibly have been avoided,” said Judge Lina Hidalgo, Harris County’s top elected official. “But until we determine that, I will ask the tough questions.”

Experts who have studied deaths caused by crowd surges say they are often a result of density — too many people packed into a small space. The crowd is often running either away from a perceived threat or toward something they want, such as a performer, before hitting a barrier.

Ernest Carter, another Astroworld attendee, said it’s common for a concert crowd to push forward as an act takes the stage, but he’d never seen anything like what happened.

“As many times I’ve been to concerts, as soon as the music starts people from the back push to get to the front. And that forces the people in the front who’ve been there for hours … it bends them over the barricades and that was the issue,” said Carter.

Carter said he was also surprised by the limited space for a two-stage event.

“I’ve never been to a festival where it was that crowded only for two stages. You have the large venue area, and then you have the VIP area — which is where I was located at the time. It was very hectic, and a lot of people kept trying to rush into the VIP section to get into the more spacious areas,” said Carter.

G. Keith Still, a visiting professor of crowd science at the United Kingdom’s University of Suffolk, has testified as an expert witness in court cases involving crowds. He said he usually does not look at eyewitness reports when in the early stages of analyzing an incident because emotions can cloud the picture, and witnesses can see only what’s immediately around them.

Based on fire codes, the venue could have held 200,000 people, but city officials limited the attendance to 50,000, Houston Fire Chief Samuel Peña said.

“It was the crowd control at the point of the stage that was the issue, especially as the crowd began to surge toward the stage,” Peña said.

The deaths called to mind a 1979 concert by The Who where 11 people died as thousands of fans tried to get into Cincinnati’s Riverfront Coliseum. Other past crowd catastrophes include the deaths of 97 people in an overcrowded Hillsborough Stadium in 1989 in Sheffield, England, and numerous disasters connected with the annual hajj in Saudi Arabia.

People in the Houston crowd reported lots of pushing and shoving during the performances leading up to Scott’s set.

Then when Scott took the stage, the crowd seemed to rush to the front, trying to get closer to the stage, said Nick Johnson, a high school senior from the Houston suburb of Friendswood who was at the concert with friends.

“Everyone was passing out around you, and everyone was trying to help each other. But you just couldn’t move. You couldn’t do anything. You can’t even pick your arms up,” Johnson said. “It just got worse and worse.”

Johnson said fans started to crush each other, and people started screaming. He said it felt like 100 degrees in the crowd.

Scott seemed to be aware that something was going on in the crowd, but he might not have understood the severity of the situation, Johnson said.

On video posted to social media, Scott could be seen stopping the concert at one point and asking for aid for someone in the audience: “Security, somebody help real quick.”

In a tweet posted Saturday, Scott said he was “absolutely devastated by what took place last night.” He pledged to work “together with the Houston community to heal and support the families in need.”

Amy Harris, a freelance photographer for The Associated Press, described an “aggressive” crowd atmosphere throughout the day because of the way fans were behaving — pushing and rushing the stage barricades and prohibited VIP and admission areas.

“It was definitely the most chaotic festival environment that I’ve been in,” Harris said. “I felt uneasy all day.”

She got trapped behind a barricade while photographing performer Don Toliver because about 300 fans rushed the area. They ended up behind the security barricade with her.

She encountered a similar scene at a different stage for the main act. She left the media pit after three songs because of the disorder, which resulted in people being pulled over the security barricade to receive medical attention.

At one point, Gerardo Abad-Garcia was pressed so tightly into the crowd that he could not move his arms off his chest. During Toliver’s performance, which came before Scott’s appearance, he started getting concerned for his safety.

“I just couldn’t breathe. I was being compressed,” he said. A security guard helped him and others climb a fence and get out.

He described the crowd during Scott’s set as a wave that was “going forward and backward.”

Some people lost their shoes, and the ground was littered with clothing and trash. He said some people tried to help those who were passed out on the ground, while other concertgoers seemed to ignore them and continued watching the show.

After Scott’s concert, Abad-Garcia saw medical personnel performing CPR on someone who appeared to be unconscious as the person was taken away on a golf cart.

Authorities did not disclose the causes of death, and the dead were not immediately identified.

Houston Police Chief Troy Finner said authorities were investigating reports of suspicious activity in the crowd, including a security officer who told police that he felt a sharp poke in his neck during the chaos and lost consciousness while being examined by first responders.

He was revived by the opioid antidote Narcan, Finner said.

Scott, one of music’s biggest young stars, founded the Astroworld Festival in 2018. The 29-year-old Houston native has been nominated for eight Grammy Awards. He has a 3-year-old daughter with Kylie Jenner, who announced in September that she’s pregnant with their second child.

Drake joined Scott on stage at the concert, which was livestreamed by Apple Music.
