The family of rising pop star Christina Grimmie has filed a wrongful death suit against a concert promoter, a security company, and the Orlando theater where she was gunned down, alleging that they failed to take adequate security measures to ensure her safety.

The suit, filed in the 9th Judicial Circuit Court of Florida on Tuesday, named AEG Live, the promoter; the Orlando Philharmonic Orchestra Plaza Foundation, which owns the theater where the Marlton native was killed; and ABC Corp., the security company.
