8 dead, numerous injured at Astroworld Festival in Houston

Officials declared a "mass casualty incident" just after 9 pm Friday during the festival where an estimated 50,000 people were in attendance, Houston Fire Chief Samuel Peña told reporters at a news conference.

"The crowd began to compress towards the front of the stage, and that caused some panic, and it started causing some injuries," the fire chief said. "People began to fall out, become unconscious, and it created additional panic." The show was called off shortly thereafter. The fire chief said "scores of individuals" were injured.

Officials transported 17 people to hospitals, including 11 who were in cardiac arrest, Peña said. It wasn't clear whether all eight who died were among the 17 that had been transported to hospitals. Many people were also treated at the scene at NRG Park, where a field hospital had been set up. About 300 people were examined at that site throughout the day, he said.

Astroworld is a two-day music festival that was scheduled to take place Friday and Saturday in Houston. The event was sold out, according to the Astroworld website. Saturday's performances have been canceled.

The deaths called to mind a 1979 concert for The Who where 11 people died and about two dozen were injured as thousands of fans tried to get into Cincinnati's riverfront coliseum.

Scott, one of music's biggest young stars, released two new songs earlier Friday, "Mafia" and "Escape Plan." The 29-year-old Houston native has been nominated for eight Grammy Awards. He has a 3-year-old daughter, Stormi, 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 - and posted photos to Instagram after the performance.

Event promoters had arranged for medical units to be on scene at the festival, however once the crowd surge began, those units were "quickly overwhelmed," Peña said.

In a 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." Houston Police Executive Assistant Chief Larry Satterwhite was near the front of the crowd and said it seemed the surge "happened all at once." "Suddenly we had several people down on the ground, experiencing some type of cardiac arrest or some type of medical episode," Satterwhite said. "And so we immediately started doing CPR, and moving people right then, and that's when I went and met with the promoters, and Live Nation, and they agreed to end early in the interest of public safety." Peña said officials did not immediately know the causes of death for the eight people who died. A medical examiner would investigate. The deceased had not been identified as of early Saturday.

Officials set up a reunification center at a hotel for family members who had not been able to reach relatives who had been in attendance at the event. Authorities were looking to connect families with festivalgoers who were transported to the hospital, "some as young as 10" years old, Harris County Judge Lina Hidalgo said.

Houston Police Chief Troy Finner called for calm and urged people not to jump to conclusions as to what caused the surge.

"I think it's very important that none of us speculate. Nobody has all the answers tonight," Finner said. He added that there have been several rumors surrounding the event that authorities would look into.

"We're going to do an investigation and find out because it's not fair to the producers, to anybody else involved, until we determine what happened, what caused the surge," he said. "We don't know, but we will find out." The Associated Press reached out to a representative for Scott but did not immediately hear back.

Finner told reporters that Scott and the event promoters cooperated with police.

Scott founded Astroworld Festival in 2018 and it has taken place at the former site of Six Flags AstroWorld each year since, except for in 2020 because of the coronavirus pandemic.

Other music events where there have been multiple fatalities in recent years include the Las Vegas massacre in 2017 when 58 people were killed at the Route 91 Harvest Festival, the so-called Ghost Ship fire in 2016 that killed 36 people in California and the 2003 Station nightclub fire that killed 100 people in Rhode Island.
