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.

On June 10, the 22-year-old YouTube sensation and competitor on The Voice, was shot and killed by 27-year-old Kevin James Loibl as she was signing autographs. Loibl was tackled by Grimmie's brother Marcus, but broke free and then killed himself.

"By doing only superficial bag checks with no body pat downs or the use of metal detectors to safeguard against concert goers bring weapons into the theater, Christina's assailant was permitted to enter the Plaza Live theater facility with two 9mm Glock handguns, two full magazines and a large hunting knife," the lawsuit said.
Grimmie's relatives are seeking a jury trial and damages for their mental pain and suffering as a result of the singer's death.

In a statement to CNN, a spokesman for the theater said that the company's thoughts were with the Grimmie family and that it would "not be speaking about this matter and allow it to be addressed through the proper legal channels."
