Several police cars were blocking off streets, and first responders could be seen rushing victims into ambulances.

In the immediate aftermath, debris could be seen on the sidewalk and the street outside the club with clothing and shoes strewn about. Early Thursday morning, a rolled-up red carpet was on the sidewalk, alongside an event poster.

Outside hospitals where victims were being treated, emotional family and friends could be seen waiting.

No one was in custody, and detectives were investigating.
