An estimated crowd of 50-thousand attended the concert, which was organized and headlined by Travis Scott. According to Houston Fire Department Chief Samuel Peña, “The crowd began to compress toward the front of the stage and that caused some panic and started causing some injuries. People began to fall out and become unconscious and that created additional panic.” Peña said that a “mass casualty” incident was triggered at 9:38pm. His team transported 17 people to the hospital – 11 of whom were in cardiac arrest at the time. While there was a medical tent on site, the festival staff was quickly overwhelmed by the situation, which led his team to dispatch as many 50 units. Eight people have died from this event.
