On Friday night in Houston, eight people were killed during a crowd surge as Travis Scott performed at the festival he headlined. Shortly after 9 p.m. Friday, the crowd began to rush the stage, yet it was over an hour from the time concertgoers began to compress towards the stage and when the performance was finally stopped.

The end result was a profound tragedy that played out in real time over social media, through deeply disturbing first-hand accounts that will surely become evidence in a spate of lawsuits.
