Civil-rights attorney Ben Crump and attorney Alex Hilliard plan to file lawsuits on behalf of more than 100 victims of the mass-casualty event that occurred at the AstroWorld Music Festival last week.

The lawyers plan to announce the lawsuits on Friday morning, according to a statement provided to Insider by a representative for Crump.

At least nine people died and more than 300 were injured as a result of a crowd surge during Travis Scott’s performance at AstroWorld in Houston, Texas, on November 6. The Houston Police Department and FBI are investigating the incident.
