CENTENNIAL, Colo. -- The civil trial for the Aurora theater shooting began Monday in Arapahoe County.
Twenty-eight families of those killed and wounded in the July 20, 2012, shooting are suing Cinemark, the company that owns the Century 16 Theater in Aurora where the attack took place.
The families are suing the theater chain for a variety of security issues. They claim the theater did not hire extra security on the night of the debut of "The Dark Knight Rises" despite having extra officers on duty for previous Friday and Saturday nights.
They claim there were no alarms on the emergency exit of the theater where the shooter made his way in. The theater chain said it was not an emergency exit.
The families also claim a door was propped open and unchecked so the shooter could return to the theater. And they claim there was no surveillance in the back of the theater, and employees and security inside never intervened to stop the shooting.
The trial is expected to last three weeks.
