A federal magistrate announced Thursday that claims of negligence and wrongful death against the Aurora, Colo. theater where a masked gunman opened fire in July should be tossed out, NBC News reported. The shooting, which left 12 people dead and 58 injured, resulted in at least 10 lawsuits against Cinemark on grounds that poor security at the theater enabled the gunman's attack, according to The Denver Post. However, Thursday's decision by U.S. Magistrate Judge Michael Hegarty applies to only seven lawsuits filed in federal court last year. Hegarty stated that under Colorado law, people wounded or families of individuals killed in the shooting are not allowed to make claims of negligence and wrongful death against the theater. The theater opened its doors last week after it closed on July 20 following the mass shooting. The suspected gunman, James Holmes, is charged with 24 counts of first-degree murder and is currently in prison awaiting trial.
