Three people wounded in the July mass shooting at a Colorado multiplex are suing the theater owner, claiming that security was lax the night a gunman opened fire and killed 12 people. Two lawsuits filed Friday against Cinemark USA Inc., owner of Century Aurora 16, allege negligence on the part of the corporation because the theater lacked adequate security or sufficient alarm systems. "Although the theater was showing a midnight premier of the movie and was expecting large crowds of people to attend the midnight showing, no security personnel were present for that showing," according to both lawsuits, which were filed by the same law firm.
