At least seven of the 10 dead after the Astroworld Festival were clustered in a small area enclosed on three sides by metal barriers that became dangerously crowded, according to a Washington Post investigation. wapo.st/3FKUslm

Using exclusive video, interviews with witnesses and expert crowd analysis, The Post reconstructed the chaos in one section of the audience at rapper Travis Scott’s music festival. wapo.st/3FKUslm

Ten fans at the Nov. 5 concert in Houston died and dozens more were injured, making it one of the most deadly concerts in the nation’s history.

The Post found that most of those who died were close to each other in the viewing area’s south quadrant. wapo.st/3FKUslm

Three concertgoers who died appeared unconscious in a pile of other fallen fans in the south quadrant only 16 minutes into the show, according to a video reviewed by The Post.

The concert continued for nearly another hour. wapo.st/3FKUslm

Around 8:30 p.m., a concert by SZA at the secondary stage ended and the audience from that show began to stream toward the main stage area, witnesses said.

As the crowd pressure increased, some concertgoers became caught in the current. wapo.st/3FKUslm

Crowd experts said the influx into the packed quadrant, with its rigid barriers, would have compressed people, increasing the crowd density and giving fans inside the section little ability to exit. The experts also faulted the layout of the barriers. wapo.st/3FKUslm

The show ended around 10:12 p.m. with Scott closing it out, running about 72 minutes in all and continuing about 42 minutes after police first reported that multiple people had been trampled. wapo.st/3FKUslm

A criminal investigation is ongoing, and the causes of the deaths have not been made public.
