Attorney Alex Hilliard, speaking at a news conference alongside victims and Crump, said festival “organizers, risk directors and security personnel” failed to protect the thousands of concertgoers.
It is unclear what Scott saw from the stage and whether he was aware of the crowd conditions, but he continued to perform until about 10:10 p.m.
First responders began to hear of crowd injuries around 9:30 p.m., and the show continued for another 40 minutes, authorities said.
Firefighters who were stationed outside the venue were not in radio communications with the emergency medical providers hired by the concert organizers as the situation unfolded, said Patrick M.
The plan identifies the role of the executive producer as well as the festival director as the only people with the authority to stop the concert.
