(AURORA, Colo.) -- The first lawsuit stemming from last week's shooting spree at an Aurora, Colo., movie theater that left 12 dead and 58 wounded was filed Tuesday by a friend of one of those killed.
According to Torrence Brown. Jr., he was left with "extreme trauma" by the incident although he was not physically injured. Brown's friend, A. J. Boik, died in the shooting-spree, which police blame on 24-year-old former doctoral student James Holmes.
The lawsuit states that doctors treating Holmes for an undisclosed illness were negligent for failing to properly supervise him.
Brown is also suing the Century 16 movie theater where the shooting took place for failing to equip the emergency exits with alarms or manning them with security guards. Witnesses said that Holmes entered through an exit door he had initially jimmied open before the movie started.
Furthermore, the lawsuit names Warner Bros., producer of The Dark Knight Rises, for excessive violence in the film, which allegedly allowed Holmes to fool people into thinking that he was part of the movie.
