According to the lawsuit, the defendants failed to take adequate security measures to ensure the safety of the performers and attendees at the concert, pointing out that security involved superficial bag checks instead of pat downs or metal detectors.

Investigators say the man who killed Grimmie was able to get into the show with two handguns, bullets and a hunting knife.
