According to Houston Fire Department records, indicators of disaster were visible hours before the tragic crowd surge at the Astroworld Music Festival a week ago.

Records acquired by USA Today show that firemen arrived to NPG Park shortly before 7 a.m. last Friday to speak with police in advance of the event.

By 10:02 a.m., firemen had reported broken barriers and “no control of participants” at the event.

According to the records, 3,000 to 5,000 concertgoers who were “not scanned” were entering the arena by 5:05 p.m.

According to the 11-page report, four concertgoers were injured during the initial rush through the gates. The mob would storm the gates at least nine more times, according to fire authorities.

The throng at a music event organized by Travis Scott, a beloved local rapper turned megastar, may be tough to regulate, concert organizers and Houston city officials understood. That’s what occurred the last time Mr. Scott conducted his Astroworld Festival, two years ago.

Nine people died as a result of the overcrowding at the popular event, which resulted in scores of lawsuits and a bevy of unsolved questions about what went wrong.

When Scott’s set eventually came to a close 12 hours later, eight people had died in the audience. After sustaining major head injuries, another female, 22-year-old Bharti Shahani, was pronounced dead several days later.

At 11:33 a.m., officials sought aid for a lady who was experiencing a seizure. As the day progressed, additional people were brought to the hospital. By 8 p.m., a hand injury had been reported to a Houston police officer.

Mr. Scott’s concert that day drew a large number of ardent followers, according to the chief, Troy Finner.

Fans had been lured to see Mr. Scott because of the ambiance and the excitement of watching music live again after the epidemic halt for months. They drove in from Dallas and San Antonio after flying in from California and Colorado. Hundreds of dollars were spent on tickets. Among the 50,000 spectators were elementary school students.

Jesse Dahl, who traveled from Denver with his 9-year-old son for the event, stated, “We literally flew down just for Astroworld. I’ve had the tickets for months.”

The records portray a terrible picture of an out-of-control scenario that was becoming worse by the hour. A number of concertgoers were taken to the hospital in ambulances that morning and afternoon.

At one point, just before 5 p.m., the Houston Police Department reported “dangerous crowd conditions.”

Hundreds of individuals would be treated by ParaDocs Worldwide, the venue’s private medical service, throughout the course of the 12 hours.

Concertgoers began demolishing barriers as early as 11 a.m., according to the records.

Several hours later, concertgoers were seen using bolt cutters to gain access to one of the parking places. Ten minutes after the bolt cutters were discovered, a third group was presumably scaling the fence of a separate lot.

The performance concluded 30 minutes sooner than planned, but almost 40 minutes after municipal officials declared a “mass casualty event.” One concern raised in the aftermath of the disaster was whether the concert should have been halted sooner; officials said that doing so would have had its own set of risks, including provoking a riot.

More than 260 individuals had been treated eight minutes before headliner and event organizer Travis Scott took the stage at 9 p.m., according to the records, which did not identify the sort of treatment. A “crush injury” was mentioned in a 9:18 p.m. entry.

“This is when it all got real,” the log says, little than half an hour into Scott’s performance.

At 9:33 p.m., police reported “multiple people trampled, passed out in front of stage.” A police operator recorded five 911 calls concerning “unconscious persons in crowd” minutes later. “Report of possible CPR.”

According to the data, a “Level One MCI” – mass casualty incident – was recorded at 9:52 p.m.

When Scott noticed someone unconscious in the crowd at 9:42 p.m., he temporarily paused his performance. It’s unclear whether he was aware of the seriousness of the crowd sinkholes.

Mr. Scott and the organizers could have intervened and halted the event, according to Fire Chief Samuel Pea.

“The one person who can really call for and get a tactical pause when something goes wrong is that performer. They have that bully pulpit and they have a responsibility,” Chief Peña said in a telephone interview on Sunday. “If somebody would have said, ‘Hey, shut this thing down and turn on the lights until this thing gets corrected’ — and that coming from the person with the mic — I think could have been very helpful.”

Mr. Scott and Live Nation have declined to answer specific questions, but have stated that they will assist the inquiry.
