AURORA, Colo. — Movie theater chain Cinemark, the owner of the Aurora theater where a shooting killed 12 people and injured 70 others, said in court documents Wednesday that it has reached an agreement with several victims over cost claims.

Dozens of victims sued the chain in state and federal court after James Holmes opened fire inside Theater 9 of the Century Aurora 16 movie theater during a midnight showing of the Batman film “The Dark Knight Rises” on July 20, 2012.

The families claimed there was not enough security to stop the gunman from carrying out the shooting.

In May, an Arapahoe County civil jury ruled  Cinemark was not liable for the shooting. After the state court verdict, U.S. District Judge R. Brooke Jackson ruled in favor of the theater chain. Both cases were appealed.

Lawyers for Cinemark sought under Colorado law to retrieve legal costs after it was found not liable in the state case, filing a bill of costs for $699,187.13 in June in Arapahoe County court.

In court documents filed Wednesday, Cinemark said it had reached a deal with all but four of the plaintiffs to drop the cost request if the victims drop their appeal.

The four remaining plaintiffs in the state case as well as the four plaintiffs who are appealing to the 10th U.S. Circuit Court of Appeals on Jackson’s ruling could be ordered to pay Cinemark’s legal bills if they don’t win their appeals.

Cinemark has not placed a value on its costs in the federal case.
