The man accused of the Batman movie massacre in Colorado last month had conversations with a classmate about wanting to kill people four months before the fateful midnight screening, according to court documents.

James Holmes, who has been charged over the shooting spree during the showing of The Dark Knight Rises that left 12 dead and 58 wounded, is alleged to have made the threat in March.

The court document also said Holmes was denied access to the University of Colorado Anschutz Medical Campus, where he was a PhD student, after making threats to a professor.
